Narrow band imaging (NBI) is an advanced endoscopic technique that uses filtered blue and green light to highlight mucosal vessel and surface patterns, allowing detection of early cancers and precancerous lesions that standard white light endoscopy can miss. The technology is built into modern endoscopes and is switched on at the touch of a button during routine procedures. According to Dr. Vipulroy Rathod, Gastroenterologist in Mumbai, “NBI changed how we look at the GI tract. The same scope, the same patient, but the lesions that white light barely shows light up clearly under NBI. Subtle Barrett’s dysplasia. Early gastric cancer in a chronic gastritis background. Flat colonic adenomas that would have been missed. It doesn’t replace careful inspection, but it makes careful inspection much more productive.” What does NBI show and how does it work? NBI works on the principle that haemoglobin absorbs specific wavelengths of light, which makes blood vessels appear with high contrast against surrounding tissue. Mucosal vessel patterns. NBI highlights the superficial capillary network on the mucosal surface. Early cancers produce irregular, distorted, or dense vessel patterns that stand out clearly from normal background mucosa. The pit pattern of glandular structures becomes more visible under NBI, which helps distinguish neoplastic from non-neoplastic lesions in the colon and stomach. Classifications like the Kudo and NICE systems are based on these patterns. Demarcation lines around lesions. NBI shows sharp borders between abnormal and normal mucosa more clearly than white light, which helps in deciding where the lesion ends and where the resection margin should be placed. Subtle colour changes from normal pink mucosa to brownish or whitish areas are amplified under NBI, particularly in the oesophagus where Barrett’s dysplasia and squamous neoplasia present as colour shifts before forming a visible mass. NBI is most useful when combined with high-definition endoscopy and magnification. Endoscopy services using modern scopes with NBI capability allow careful targeted inspection of high-risk areas rather than relying on random biopsies alone, which is the older approach to screening for early disease. Where is NBI most useful clinically? NBI has the strongest evidence base in a few specific clinical situations where early cancer detection changes management. Barrett’s oesophagus surveillance. NBI improves detection of dysplasia in Barrett’s patients, allowing targeted biopsies of visible lesions rather than random four-quadrant biopsies of normal-looking mucosa. Early gastric cancer screening in patients with chronic atrophic gastritis or intestinal metaplasia. NBI with magnification picks up subtle lesions that look unremarkable under white light. Colorectal polyp characterisation. NBI helps distinguish hyperplastic from adenomatous polyps in real time, reducing unnecessary polypectomy and allowing optical diagnosis in selected cases. Squamous cell oesophageal cancer in high-risk patients, particularly heavy smokers and drinkers. NBI lights up flat brownish areas that suggest early squamous neoplasia. NBI improves detection but it doesn’t replace endoscopic experience and time spent inspecting. Read more on Colon cancer screening for how NBI fits into the broader screening strategy across different GI cancer types. Why choose Dr. Vipulroy Rathod for NBI endoscopy? Dr. Vipulroy Rathod has been performing advanced endoscopy at Fortis Hospital Mulund for over three decades, with modern NBI-capable systems and the volume of cases that builds the pattern recognition NBI requires to be useful. The technology only adds value when the operator knows what they’re looking for, which is why NBI training matters as much as equipment availability in any centre. The mistake some centres make is assuming NBI alone improves cancer detection. It doesn’t. NBI improves detection when used by experienced operators who do careful targeted inspection. In less experienced hands, the additional information gets overlooked or misinterpreted, which is part of why NBI uptake has been slower than expected in many countries despite the supporting evidence. Book your consultation today with one of India’s most experienced specialists for NBI endoscopy and early GI cancer detection. Book Appointment Call now Frequently Asked Questions Is NBI a separate procedure or part of regular endoscopy? Part of regular endoscopy. NBI is built into modern scopes and switched on during the procedure at the operator’s discretion. Does NBI involve any extra preparation? No. The preparation for NBI endoscopy is the same as for any standard upper GI endoscopy or colonoscopy. Can NBI replace biopsies? In selected cases yes, particularly for small colorectal polyps where optical diagnosis is supported by current guidelines. For most other situations, biopsy remains the standard for tissue confirmation. Is NBI available in most Indian hospitals? Increasingly available in larger centres and tertiary hospitals, though not yet universal. Patients should ask whether the centre uses NBI-capable scopes for surveillance and high-risk screening procedures.

Endoscopic submucosal dissection (ESD) is an advanced endoscopic technique that removes early-stage GI cancers, large polyps, and submucosal lesions in a single intact piece through the scope. The procedure uses a specialised electrosurgical knife passed through a standard endoscope, allowing en bloc resection of lesions up to several centimetres in size without open or laparoscopic surgery. According to Dr. Vipulroy Rathod, Gastroenterologist in Mumbai, “ESD is what changed the management of early GI cancer. Lesions that needed gastrectomy or oesophagectomy can now be removed through a scope, in one piece, with the patient going home the next day. The key is en bloc resection. That gives the pathologist a complete specimen and tells us whether the cancer was confined to the mucosa or has gone deeper, which decides whether anything else needs to follow.” What conditions are treated with ESD? ESD is reserved for lesions where en bloc resection is essential, mainly early cancers and large or complex polyps. Early gastric cancer. Tumours confined to the mucosa or superficial submucosa, without lymph node involvement, are the classic ESD indication. Cure rates match surgical resection in selected cases. Early oesophageal cancer including squamous cell carcinoma and Barrett’s adenocarcinoma in superficial stages. ESD provides definitive treatment while preserving the oesophagus completely. Large colorectal polyps and laterally spreading tumours. Lesions over 20 mm or those with features suggesting they can’t be safely removed by piecemeal EMR. ESD allows complete en bloc removal regardless of size. Submucosal tumours and certain neuroendocrine tumours in selected locations and sizes. ESD or tunnelling techniques remove these without breaching the muscle layer or needing surgery. The decision to do ESD depends on pre-procedure imaging assessment. Advanced endoscopy units with chromoendoscopy and EUS for accurate depth assessment select the right cases for ESD, distinguishing them from the lesions that need surgery instead. How is ESD performed and what is recovery like? The procedure uses a specialised electrosurgical knife and follows a structured sequence of marking, injection, incision, and dissection. Marking the margins. The borders of the lesion are marked with electrocautery dots, usually with a five-millimetre margin around visible disease. This defines the resection field. A submucosal injection lifts the lesion away from the muscle layer underneath, creating a working space. The solution is often mixed with dye to make the submucosal layer easier to see during dissection. Circumferential incision and dissection. The mucosa is incised along the marked margin, then the submucosal layer is dissected away from the muscle using the knife, freeing the lesion in one piece. Mucosal defect closure with clips at the end of the procedure. Most patients go home within twenty-four to forty-eight hours with normal activity resumed in a few days. ESD has a learning curve and complication rates fall sharply with operator experience. Read more on endoscopic procedures for related advanced submucosal techniques used in different clinical situations. Why choose Dr. Vipulroy Rathod for ESD? Dr. Vipulroy Rathod has been performing advanced endoscopic resection techniques at Fortis Hospital Mulund for over three decades, including ESD for early GI cancers and large lesions that would otherwise require surgical resection. The training and equipment requirements for ESD are significant, and the procedure is performed at only a small number of centres in India with the volume needed to do it safely. The reason ESD needs experienced hands is the dissection itself. The plane between the submucosa and muscle is narrow and the consequences of going wrong are serious. Perforation, bleeding, incomplete resection. The complication rate falls dramatically with operator experience, which is why ESD volume per operator matters more than equipment availability in any centre. Book your consultation today with one of India’s most experienced specialists for ESD and advanced endoscopic resection. Book Appointment Call now Frequently Asked Questions Is ESD as effective as surgery for early GI cancer? Yes, in appropriately selected cases. Cure rates match surgical resection when the lesion is correctly staged and the resection achieves clear margins. How long does an ESD procedure take? Anywhere from one to four hours depending on the size and location of the lesion. Large gastric ESDs and complex colorectal lesions take longer than smaller superficial cases. What are the main risks of ESD? Bleeding, perforation, and incomplete resection are the principal complications. All three are uncommon in experienced hands and most can be managed endoscopically when they occur. Is ESD available across India? Limited. Only a small number of centres offer ESD with the equipment and volume needed for safe practice. Most patients are referred to high-volume specialist units.

Third space endoscopy is a category of advanced endoscopic procedures that work in the submucosal layer of the GI tract, between the mucosa and the muscle wall, to treat conditions previously requiring surgery. It includes peroral endoscopic myotomy (POEM) for achalasia, submucosal tumour resection, and Zenker’s diverticulum repair. The approach uses the same scope used for routine endoscopy with specialised tools. According to Dr. Vipulroy Rathod, Gastroenterologist in Mumbai, “Third space endoscopy is one of the bigger shifts in GI procedural medicine over the last fifteen years. Conditions that needed open chest surgery or laparoscopy can now be treated through the scope alone. Achalasia. Submucosal tumours. Zenker’s diverticulum. Patients walk in the morning and walk out the same day. The recovery is dramatically shorter, the cosmetic result is invisible, and the outcomes match surgery in most published series.” What conditions are treated with third space endoscopy? The technique applies to a defined set of conditions where surgical access to the muscle layer is needed but the mucosa above can be preserved. Achalasia. Peroral endoscopic myotomy (POEM) cuts the lower oesophageal sphincter muscle through a submucosal tunnel. Replaces Heller myotomy in most appropriate cases, with similar long-term outcomes and faster recovery. Submucosal tumours like gastrointestinal stromal tumours (GISTs) and leiomyomas in the oesophagus, stomach, or duodenum. These can be respected through endoscopic submucosal dissection or tunnelling techniques without open surgery. Zenker’s diverticulum. A pharyngeal pouch causing dysphagia and regurgitation can be treated with Z-POEM, cutting the cricopharyngeal muscle endoscopically and avoiding open neck surgery. Gastroparesis with refractory symptoms. G-POEM (pyloromyotomy) cuts the pylorus muscle endoscopically, improving gastric emptying in patients who haven’t responded to medical management. The technique has expanded rapidly across centres in the last decade. Advanced endoscopy services with the equipment and training to perform third space procedures are still limited in India, which means access depends heavily on which centre a patient is referred to. How is third space endoscopy performed? The procedure uses a working channel and specialised electrosurgical knives passed through a standard endoscope. The anatomy of the submucosal space is what makes the technique possible. Submucosal injection. A solution is injected under the mucosa to create a working space between the mucosa and the muscle layer underneath. This separates the layers and reduces injury risk during cutting. A small mucosal incision is made several centimetres proximal to the target area, then a tunnel is dissected underneath through the submucosal space until the area of interest is reached. Targeted treatment. Depending on indication, the muscle layer is cut for myotomy, the tumour is dissected free, or the diverticular septum is divided. The treatment is precise and limited to the target structure. Mucosal closure at the entry point with endoscopic clips. This seals the submucosal tunnel from the lumen and allows healing without leak in the vast majority of cases. Recovery is short and the cosmetic result is invisible because there’s no incision through the skin. Read more on advanced GI procedures for related advanced endoscopic techniques used in complex GI conditions. Why choose Dr. Vipulroy Rathod for third space endoscopy? Dr. Vipulroy Rathod has been performing advanced endoscopic procedures at Fortis Hospital Mulund for over three decades, with experience in submucosal techniques, POEM, and the broader range of third space endoscopy procedures that few Indian centres can offer at volume. The training and equipment requirements are significant, which is part of why access to these procedures remains limited despite their proven benefits in the patient groups who need them. The decision to undergo a third space procedure isn’t only about which condition the patient has. It’s about whether the centre doing the procedure has the volume, the equipment, and the experience to handle the case safely and to manage complications if they arise. Patients should ask about case numbers before agreeing to any third space procedure. Book your consultation today with one of India’s most experienced specialists for advanced endoscopic procedure assessment and treatment. Book Appointment Call now Frequently Asked Questions Is third space endoscopy painful? The procedure itself is done under general anaesthesia or deep sedation and patients don’t feel it. Some chest or abdominal discomfort for a day or two afterwards is normal and settles on its own. How long is recovery? Most patients go home within twenty-four to forty-eight hours after the procedure, with normal activity resumed within a week. The recovery is significantly shorter than surgical alternatives for the same conditions. Is POEM as good as Heller myotomy for achalasia? Outcomes are similar in published series and meta-analyses, with comparable long-term symptom relief and slightly different side-effect profiles, particularly regarding post-procedure reflux which is more common after POEM. Are these procedures available across India? Limited. Only a small number of centres offer third space endoscopy with the volume and equipment needed to do it safely. Most patients are referred to high-volume centres for these specific procedures.

ERCP and surgery are two different approaches to bile duct disease. ERCP is a minimally invasive endoscopic procedure that accesses the bile duct through the mouth and duodenum, used for stone extraction, stricture dilatation, stent placement, and biliary drainage. Surgery is reserved for cases where ERCP has failed, where the underlying disease is surgically resectable, or where biliary reconstruction is required after major duct injury. Most bile duct problems are now managed endoscopically. Surgery becomes the answer only when endoscopy can’t reach or can’t fix what needs fixing. According to Dr. Vipulroy Rathod, Gastroenterologist in Mumbai, “Patients hear bile duct problems and assume surgery is next. For most conditions, that’s no longer true. ERCP handles stones, strictures, leaks, and drainage. Surgery still has a role, but it’s reserved for the cases ERCP can’t manage rather than the default. Getting that order right matters because surgery in this area carries real risk.” ERCP vs Surgery at a glance Factor ERCP Surgery Approach Through a scope Open or laparoscopic Recovery One to two days Two to four weeks Anaesthesia Sedation, short General, prolonged Use today First-line treatment Reserved for failed cases When is ERCP the right approach? ERCP handles most bile duct problems through endoscopic access alone, without any incision. Common bile duct stones: The classic indication for ERCP. Stones are removed using basket or balloon extraction after sphincterotomy, often in a single session, with success rates above ninety-five percent. Benign biliary strictures from chronic pancreatitis, primary sclerosing cholangitis, or post-surgical scarring. ERCP allows balloon dilatation and stent placement, often with repeated sessions over months until the duct stays open. Bile leaks after cholecystectomy: ERCP with sphincterotomy and stent placement closes most post-operative bile leaks without further surgery, with the stent removed once healing is confirmed. Malignant biliary obstruction from pancreatic cancer, cholangiocarcinoma, or other tumours. Stent placement relieves jaundice and prevents cholangitis, allowing chemotherapy to proceed in patients unfit for surgery. ERCP is the first-line approach for most bile duct problems today. Pancreatic and biliary stone extraction services that combine ERCP with EUS for difficult anatomy avoid the gap where patients are sent to surgery prematurely because standard ERCP access wasn’t possible. When is surgery still necessary? Surgery hasn’t been replaced by ERCP entirely. Specific indications still require operative management. Failed ERCP access: Altered surgical anatomy, large impacted stones, or technical failure of standard cannulation may require surgical exploration of the bile duct. EUS-guided rendezvous has reduced this group considerably but not eliminated it. Resectable bile duct cancer: Cholangiocarcinoma and gallbladder cancer with surgical cure intent need formal resection, not endoscopic palliation. The decision between resection and stenting depends on staging. Major bile duct injury after surgery: Significant disruption of the bile duct, usually after laparoscopic cholecystectomy, often needs surgical reconstruction with Roux-en-Y hepaticojejunostomy rather than endoscopic management. Complications of ERCP: Perforation, severe bleeding not controlled endoscopically, or recurrent strictures that have failed multiple dilatation attempts may require surgical revision in selected cases. The surgical group is smaller today than it was twenty years ago. Read more on how biliary stones are treated endoscopically for a closer look at one of the conditions where endoscopic management has largely replaced surgical reconstruction. Why choose Dr. Vipulroy Rathod for bile duct management? Dr. Vipulroy Rathod has been performing ERCP at Fortis Hospital Mulund since the late 1990s, with experience across stone extraction, stricture dilatation, leak management, biliary stenting, and the EUS-guided rendezvous procedures that get into ducts when standard ERCP can’t. The volume of biliary endoscopy in the unit is among the highest in India, which matters because complication rates fall sharply with operator experience in this field. The judgment that matters most in bile duct disease is knowing when ERCP can handle it and when surgery is the better option. Pushing ERCP in cases that genuinely need surgery wastes time and adds risk. Sending patients to surgery when ERCP would have worked exposes them to a much bigger operation than necessary. Getting that call right comes from doing both kinds of cases at volume. Book your consultation today with one of India’s most experienced specialists for bile duct assessment and ERCP management. Book Appointment Call now Frequently Asked Questions Is ERCP safer than surgery? Generally yes in terms of immediate complications and recovery, but ERCP has its own risks including pancreatitis, bleeding, and perforation that need experienced hands to manage. Can all bile duct stones be removed by ERCP? Yes in the large majority of cases. Very large or impacted stones may need cholangioscopy with electrohydraulic lithotripsy first, with surgery reserved for the rare cases that fail even advanced endoscopic techniques. How long is recovery after ERCP?  Most patients go home the same day or the following morning, with normal activity resumed within two to three days. Surgery in comparison requires two to four weeks of recovery depending on the procedure. When should I see a specialist for bile duct problems?  Any patient with jaundice, recurrent cholangitis, suspected stones, or imaging showing duct dilatation should be assessed by a specialist with experience in both ERCP and surgical referral.

Recurrent gallstone attacks happen when stones in the gallbladder repeatedly block the cystic duct or migrate into the common bile duct, causing episodes of biliary colic, cholecystitis, or cholangitis. The underlying cause is usually unchanged anatomy and physiology, the same gallbladder, the same stones forming for the same reasons, with each attack carrying its own risk of complications. Definitive treatment is cholecystectomy, because medical management of attacks doesn’t address why the stones formed in the first place. Patients with recurrent episodes shouldn’t wait for the next one to plan surgery. According to Dr. Vipulroy Rathod, Gastroenterologist in Mumbai, “Patients often manage one or two gallstone attacks and wait, hoping the next one won’t come. It usually does. Each attack carries its own risk. Pancreatitis. Cholangitis. Gangrenous gallbladder. The mistake isn’t having stones. It’s waiting for the third or fourth episode to do something definitive, when surgery after the first attack would have prevented all the ones that followed.” What conditions drive recurrent gallstone attacks? The cause is rarely random. Specific patient factors, stone characteristics, and behavioural patterns drive the cycle. Multiple small stones. Small stones are more likely to migrate from the gallbladder into the cystic or common bile duct, causing repeated obstruction. Large solitary stones tend to stay put, but small ones travel. Female sex, age above 40, obesity, rapid weight loss, and pregnancy all raise the underlying risk of stone formation and recurrence. These factors don’t go away between attacks, so the gallbladder keeps producing stones at the same rate. Cholesterol supersaturation in bile. Most gallstones are cholesterol-based, formed when bile becomes oversaturated with cholesterol relative to bile salts and lecithin. The supersaturation continues after each attack unless the gallbladder is removed. Conditions like haemolysis, cirrhosis, ileal disease, and certain medications produce pigment stones rather than cholesterol stones. The underlying disease keeps driving stone formation regardless of how many attacks have been managed. The cycle continues until the gallbladder is removed. Pancreatic and biliary stone extraction services that combine ERCP for common bile duct stones with planned cholecystectomy avoid the gap where patients are managed for each attack separately while the underlying problem remains untreated. How are recurrent gallstone attacks treated definitively? Definitive treatment means removing the source. Symptom management treats the attack but not the cause. Laparoscopic cholecystectomy. The standard treatment for recurrent symptomatic gallstones. Removes the gallbladder along with all stones inside, preventing future attacks completely in the large majority of patients. ERCP with stone extraction is needed alongside surgery when stones have migrated into the common bile duct. The combination of ERCP followed by cholecystectomy is the standard approach for patients presenting with choledocholithiasis. Timing of surgery matters. Cholecystectomy during the index admission for cholecystitis or pancreatitis is now preferred over delayed surgery, with better outcomes and shorter overall recovery in most patient groups. Patients unfit for surgery may need percutaneous cholecystostomy as a temporary measure, with later interval cholecystectomy when fitness allows or long-term tube management in patients who can’t safely undergo any operation. Surgery prevents future attacks reliably in most patients. Read more on gallstone pancreatitis for one of the more serious complications of recurrent gallstones that can develop without warning when a stone migrates at the wrong moment. Why choose Dr. Vipulroy Rathod for recurrent gallstone management? Dr. Vipulroy Rathod has been managing recurrent gallstone disease at Fortis Hospital Mulund since the late 1990s, with coordinated care across gastroenterology and surgical teams that makes timely cholecystectomy possible for patients who arrive mid-flare. Many patients arrive after multiple admissions for biliary colic, cholangitis, or pancreatitis, when earlier surgery would have prevented the cumulative damage that built up across episodes. The mistake patients usually make is treating each attack as an isolated event rather than part of a pattern. Definitive surgery isn’t a last resort. It’s the appropriate treatment for recurrent symptomatic gallstones, with low complication rates and a high success rate when done laparoscopically in experienced hands. Book your consultation today with one of India’s most experienced specialists for recurrent gallstone assessment and treatment planning. Book Appointment Call now Frequently Asked Questions Can gallstones be dissolved with medication? Ursodeoxycholic acid dissolves some small cholesterol stones over many months, but stones usually return after stopping treatment. Surgery is more reliable. Does diet alone prevent recurrent attacks? No. Diet may reduce attack frequency in some patients, but the underlying stone formation continues regardless of dietary changes. Can I live without a gallbladder? Yes. Bile flows directly from the liver into the intestine after cholecystectomy, and most patients have no long-term symptoms. A small minority develop mild diarrhoea or bile acid malabsorption that responds to treatment. How urgent is surgery after a gallstone attack? Increasingly urgent. Current guidelines favour cholecystectomy during the index admission for cholecystitis or pancreatitis rather than delayed surgery weeks later, because outcomes are better and the risk of further attacks during the waiting period is real.

Gallbladder polyps are growths on the inner wall of the gallbladder, mostly benign and usually found incidentally on ultrasound. The concern is the small minority that can turn malignant or already contain cancer at the time of detection. Risk depends on size, age, presence of gallstones, and underlying conditions. Polyps under 10 mm in a young patient without other features rarely need anything beyond follow-up scans. Larger polyps, rapidly growing ones, or polyps in higher-risk patients usually need cholecystectomy. The judgment is in distinguishing which is which. According to Dr. Vipulroy Rathod, Gastroenterologist in Mumbai, “Most gallbladder polyps are benign. Cholesterol polyps. Inflammatory polyps. Hyperplasia. None of those turn into cancer. So why do we still recommend follow-up for every polyp found on a routine scan? Because the small percentage that are adenomatous look identical on imaging, and the only way to know which group a patient is in is serial monitoring with surgical referral for the ones that show concerning features.” What types of gallbladder polyps exist and which are concerning? Polyps fall into a few categories. Most are non-neoplastic and stay benign throughout life. Cholesterol polyps. The commonest type. Around sixty percent of gallbladder polyps fall into this category, made of cholesterol-laden cells, small and often multiple. No malignant potential and rarely cause symptoms. Are inflammatory polyps dangerous? Almost never. These form after chronic gallbladder inflammation, usually alongside gallstones or recurrent cholecystitis, and have no cancer risk in themselves. Adenomatous polyps. True neoplastic lesions with malignant potential. Rare but the ones that drive surgical decisions. Risk of malignancy rises sharply with size, particularly above 10 mm. Adenomyomatosis is wall thickening that mimics a polyp on ultrasound. Not actually a polyp but often picked up the same way. Benign in itself, with imaging confirmation needed to distinguish it from a true polyp. The features that change the workup are well-defined. Endoscopic ultrasound gives better resolution than transabdominal ultrasound for assessing polyp characteristics, particularly in lesions where the type isn’t clear and the size sits close to the surgical threshold. When should a gallbladder polyp be removed? The decision rests on a combination of size, growth, patient factors, and concerning imaging features rather than any single criterion. Size above 10 mm. The single most important risk factor. Polyps at this size carry significantly higher malignancy risk and most guidelines recommend cholecystectomy regardless of other factors. Growth on serial scans matters even in smaller polyps. A 6 mm polyp growing to 9 mm over a year often warrants surgery even though neither size alone would trigger the recommendation. Age above 50. Polyps in older patients carry higher malignant potential than equivalent-sized polyps in younger patients. The combined size and age threshold drops in this group. Other concerning features. Solitary polyp with broad base. Sessile rather than pedunculated morphology. Primary sclerosing cholangitis. Indian or East Asian ethnicity. Coexisting gallstones. Any of these raise the threshold for intervention. Most patients don’t meet criteria and simply need follow-up scans. Read more on gallstone disease management for how gallbladder pathology fits into the broader picture, particularly when polyps and stones coexist. Why choose Dr. Vipulroy Rathod for gallbladder polyp assessment? Dr. Vipulroy Rathod has been managing biliary disease at Fortis Hospital Mulund since the late 1990s. Routine cholecystectomy cases. Complex polyp risk stratification. EUS-based assessment of indeterminate lesions. The patients who arrive after being told their polyp warrants urgent surgery without proper risk stratification. The patients who arrive having been told it’s nothing when family history and ethnicity put them in a higher-risk category. Both groups end up in the same clinic with very different management plans. The judgment in gallbladder polyp management sits between two errors. Over-treat a benign cholesterol polyp and the patient gets unnecessary surgery. Under-treat a small adenomatous polyp that turns malignant over the following year and the consequences are far worse. Volume and proper imaging assessment are what keep both errors rare. Book your consultation today with one of India’s most experienced specialists for gallbladder polyp assessment and surveillance. Book Appointment Call now Frequently Asked Questions Are gallbladder polyps cancerous? Rare cases of gallbladder polyps are cancerous. How often should small polyps be monitored?  Polyps under 6 mm need ultrasound every six to twelve months for two to three years. After that, less frequently if size and morphology stay stable, and the surveillance can be relaxed further or stopped completely in low-risk patients with consistently unchanged scans over a longer follow-up period. Does ethnicity affect polyp risk?  Yes, Indian and East Asian patients carry higher malignant potential for the same polyp size. What surgery is done for gallbladder polyps?  Laparoscopic cholecystectomy  is done for gallbladder polyps Disclaimer: This blog is intended for informational and educational purposes only and should not be considered medical advice.

Biliary strictures are narrowings of the bile duct that obstruct bile flow. They are treated endoscopically through ERCP using balloon dilatation, plastic or metal stent placement, and increasingly with EUS-guided drainage when ERCP can’t reach. The approach depends on whether the stricture is benign or malignant, where it sits, and how the patient has responded to previous interventions. Most cases are managed without surgery, though malignant strictures often need long-term stenting alongside chemotherapy, and benign post-surgical strictures may need months of progressive dilatation before the duct stays open. According to Dr. Vipulroy Rathod, Gastroenterologist in Mumbai, “Biliary strictures used to mean surgery. Now most cases are managed endoscopically. Balloon dilatation. Plastic stents. Fully covered metal stents. EUS-guided drainage when ERCP fails. Each option fits a specific clinical scenario, and choosing the right one upfront avoids the repeat procedures that come with the wrong choice.” What are the types of biliary strictures and what causes them? Strictures are classified as benign or malignant. The cause changes the approach and the duration of treatment. Benign post-surgical strictures. Most often follow cholecystectomy, liver transplant, or biliary surgery. Scar tissue develops at the anastomosis or injury site over months, causing progressive narrowing. Inflammatory strictures from chronic pancreatitis, primary sclerosing cholangitis, autoimmune cholangitis, and IgG4-related disease. These behave differently from post-surgical strictures and often need disease-specific treatment alongside endoscopy. Malignant strictures. Cholangiocarcinoma, pancreatic head cancer, gallbladder cancer, metastases compressing the bile duct. Often the first presentation is jaundice, and stenting relieves symptoms while allowing chemotherapy to start. Stones impacted in the bile duct cause functional strictures. These usually resolve once the stone is removed through ERCP, though long-standing impaction occasionally leaves residual narrowing that needs separate dilatation. The cause dictates the treatment plan. Pancreatic and biliary stone extraction services that combine stone removal with stricture assessment in the same ERCP session avoid repeat procedures and allow simultaneous management when both problems coexist, which they often do. How are biliary strictures treated endoscopically? Endoscopic management runs on a sequence of steps, starting with the least invasive option that controls the problem. Balloon dilatation. A balloon catheter passed through the scope to the stricture and inflated to a controlled diameter. First-line for many benign strictures, with multiple sessions over months sometimes needed before the duct stays open. Plastic stent placement keeps the duct open after dilatation. Standard for benign strictures, with multiple stents placed alongside each other to maximise lumen diameter. Exchanged every three to six months until response is stable. Fully covered self-expanding metal stents. Used in malignant strictures and increasingly in benign refractory cases. Stay in place longer than plastic stents and produce larger lumen diameter, though cost and removability considerations vary by case. EUS-guided biliary drainage. Reserved for cases where ERCP has failed, often due to altered surgical anatomy or duodenal obstruction. The duct is accessed directly through the stomach or duodenum under ultrasound guidance. Choosing between stent types and timing of exchanges is what separates successful from problematic outcomes. Read more on bile duct cancer for one of the more challenging causes of biliary stricture that often requires complex endoscopic management alongside oncology treatment. Why choose Dr. Vipulroy Rathod for biliary stricture management? Dr. Vipulroy Rathod has been doing biliary endoscopy at Fortis Hospital Mulund since the late 1990s. ERCP. EUS-guided drainage. Cholangioscopy. The difficult anatomy cases where standard approaches have already failed. Stricture management is one of the higher-volume areas of biliary endoscopy in the unit, with patients referred from across India and abroad for cases that haven’t responded to initial treatment elsewhere. The challenge in stricture management isn’t usually the first dilatation. It’s the longer-term plan. Choosing the right stent. Knowing when to exchange. Knowing when to escalate to metal stents or surgical referral. Getting that sequence right is what avoids years of repeat procedures and incomplete relief. Book your consultation today with one of India’s most experienced specialists for biliary stricture assessment and endoscopic management. Book Appointment Call now Frequently Asked Questions Are biliary strictures painful? Biliary strictures are often painful. The pain is typically a sharp or cramping ache in the upper right abdomen that can radiate to the back and right shoulder.  How long does endoscopic stricture treatment take? Most benign strictures need repeated procedures over six to twelve months. Malignant strictures are usually managed with longer-lasting metal stents, with exchanges every few months as needed. Can biliary stents stay in permanently? Plastic stents need exchange every three to six months because they block over time. Metal stents can stay longer, sometimes indefinitely in malignant cases where the patient’s overall trajectory means the stent is functionally a permanent fixture rather than a temporary measure, particularly in palliative cholangiocarcinoma and pancreatic cancer management. When is surgery needed for a biliary stricture? Surgery for a biliary stricture is typically reserved for cases where the narrowing is caused by a malignant tumor, the stricture is too severe to be managed by less invasive procedures, or non-surgical treatments have failed.  Disclaimer: This blog is intended for informational and educational purposes only and should not be considered medical advice.

Bile duct cancer, also called cholangiocarcinoma, is a rare and aggressive malignancy of the cells lining the bile ducts. It can arise anywhere along the biliary tree, from inside the liver down to where the duct enters the duodenum. The classification follows location, intrahepatic, perihilar, distal. Most patients present late because the early disease is silent. Jaundice. Weight loss. Itching that won’t go away. By the time these appear, treatment options have already narrowed. According to Dr. Vipulroy Rathod, Gastroenterologist in Mumbai, “Cholangiocarcinoma is hard to catch early. The ducts sit deep in the abdomen. Imaging shows duct dilatation. Often it doesn’t show the tumour itself. Patients arrive having been worked up for hepatitis or gallstones for weeks before anyone thinks of cancer. By then, resectability has often already gone.” What are the types of cholangiocarcinoma and how do they present? Classification follows location along the biliary tree. Location dictates symptoms, workup, and what treatment is possible. Intrahepatic cholangiocarcinoma. Inside the liver. Often a liver mass on imaging done for something else. Perihilar is the commonest type. Sits at the junction where the right and left hepatic ducts join, also called a Klatskin tumour. Presents as painless obstructive jaundice when the tumour blocks bile flow, and is often the hardest type to fully resect because of the proximity to major vascular structures and the need for extensive liver and bile duct resection together. Distal cholangiocarcinoma. Lower bile duct as it passes through the pancreas. Mimics pancreatic head cancer in presentation, gets worked up the same way, and the Whipple procedure is the operation when resectable. Risk factors matter but only in a minority. Primary sclerosing cholangitis. Choledochal cysts. Chronic biliary infection. Hepatitis B and C. Most cases occur in patients without any identifiable risk factor at all, which is part of what makes early detection so difficult and why surveillance is currently limited to high-risk groups rather than the general population. The workup needs both imaging and tissue. Endoscopic ultrasound with fine-needle aspiration is often the only way to obtain tissue from perihilar and distal lesions, while ERCP with brush cytology or cholangioscopy adds diagnostic yield in selected cases. How is cholangiocarcinoma treated? Treatment hinges entirely on resectability. Surgery offers the only realistic cure, though most patients aren’t surgical candidates by the time they present. Surgery. Liver resection for intrahepatic, extended liver and bile duct resection for perihilar, Whipple for distal. Five-year survival twenty to forty percent depending on type and stage. Neoadjuvant chemotherapy with capecitabine and gemcitabine improves outcomes in selected resectable cases, particularly perihilar tumours, and is increasingly used as part of multidisciplinary planning rather than reserved for relapse, which represents a real shift in how this disease is approached in major centres over the past decade. Liver transplant. Highly selected early perihilar cases. Strict criteria. Palliative biliary stenting for unresectable disease. ERCP or EUS-guided stent placement relieves jaundice, prevents cholangitis, and lets patients tolerate chemotherapy. The cornerstone of palliative care alongside systemic gemcitabine-cisplatin treatment, which remains the backbone of medical management in this group. Most cholangiocarcinoma patients need coordinated input from surgery, oncology, and interventional endoscopy from the start.

Dr. Vipulroy Rathod has been doing endoscopic assessment, biliary drainage, and tissue diagnosis of cholangiocarcinoma at Fortis Hospital Mulund since the late 1990s. EUS-guided biopsy. ERCP with brush cytology. Percutaneous drainage when endoscopic access fails. The volume of difficult biliary work that builds skill in unusual presentations is hard to acquire in centres that see one or two cases a year. The reason cholangiocarcinoma needs experienced hands isn’t only the diagnosis. It’s the staging, the biliary drainage strategy, and the question of resectability that often hinges on imaging and EUS findings together. Getting any of those wrong sends the patient down the wrong pathway from the start.

Book Appointment Call now Frequently Asked Questions What are the early signs of bile duct cancer? Painless jaundice. Itching. Dark urine. Pale stools. Unexplained weight loss. These are the commonest features at presentation, with the jaundice often being the trigger that finally brings the patient to medical attention after weeks of vaguer symptoms that had been attributed to something else. Is cholangiocarcinoma curable? Only with successful resection. How is bile duct cancer diagnosed? MRI cholangiopancreatography is the starting imaging investigation. EUS with biopsy gives tissue from perihilar and distal lesions. ERCP with brush cytology adds further yield, and CT staging completes the workup before any treatment decision is finalised. Can bile duct cancer be screened for?  Not generally. Disclaimer: This blog is intended for informational and educational purposes only and should not be considered medical advice.

Ulcerative Colitis While Pregnant: What You Need to Know A pregnancy diagnosis, planned or unplanned, changes the questions a person with ulcerative colitis is suddenly asking themselves. Will the disease flare again once hormones shift? Is it safe to keep taking the same medication? Can the pregnancy even be carried to term without complications? For the large majority of patients, the answer is reassuring: a healthy pregnancy is very much achievable, provided the disease is planned around rather than left to chance. Dr. Vipulroy Rathod, a globally acclaimed gastroenterologist in Mumbai, India, has spent more than three decades treating inflammatory bowel disease, including ulcerative colitis, and has walked many patients through this exact life stage. In his experience, the single biggest predictor of how a pregnancy unfolds is not the diagnosis itself but the state of the disease at the moment of conception. Patients who become pregnant while their disease is quiet tend to stay that way; patients who conceive mid-flare are more likely to see that flare persist or worsen. At his practice in Mumbai, Dr. Rathod pairs advanced endoscopic evaluation with close coordination alongside each patient’s obstetrician, so that ulcerative colitis management and pregnancy care are never working against each other. His approach to inflammatory bowel disease treatment in Mumbai is built around exactly this kind of long-term, life-stage planning rather than treating flares in isolation. Does Ulcerative Colitis Affect Fertility and Pregnancy? Ulcerative colitis on its own does not meaningfully lower a person’s chances of conceiving, particularly when the disease is inactive. Fertility during remission tends to run close to that of the general population. There is one notable exception: surgery that creates an internal pouch from the small intestine, sometimes needed in more severe or long-standing disease, can reduce fertility because of scarring around the pelvis. Anyone considering this type of surgery should raise fertility as part of that conversation, ideally before the procedure rather than after. Pregnancy development and progression is closely linked to the severity and extent of the disease after a positive conception takes place. A flare of the condition either at the time of conception or later during pregnancy A lot increases chances of an early delivery, birth of a baby with lower than normal weight, and even miscarriage according to the seriousness of the situation. However, interestingly that women with active ulcerative colitis who go on to conceive and carry baby to term have an increased risk of complications during pregnancy, but this does not appear to be a consequence of Really they are pregnant but rather results of continued inflammation. Planning a Pregnancy With Ulcerative Colitis Time conception around remission. A period of stable, medication-controlled remission lasting three to six months before trying to conceive gives the best odds of a settled pregnancy. Have your medications reviewed early. A few drugs, methotrexate being the clearest example, need to be stopped well ahead of conception, while most maintenance treatments can continue without interruption. Check nutritional status. Iron, folate, vitamin D, and vitamin B12 are worth testing and correcting beforehand, since bowel inflammation can interfere with how well these nutrients are absorbed. Bring your obstetrician and gastroenterologist together early. When both specialists are aligned from the outset, patients are far less likely to receive conflicting advice partway through pregnancy. Resist the urge to stop treatment out of caution. Quietly discontinuing medication for fear of harming the baby is, ironically, one of the more common triggers for a flare during pregnancy. Which Ulcerative Colitis Medications Are Considered Safe During Pregnancy? Few questions cause more anxiety among pregnant patients than this one, and unfortunately, a lot of outdated or overly cautious information still circulates. The broader clinical picture is worth holding onto: uncontrolled ulcerative colitis poses a greater risk to a pregnancy than most of the standard treatments used to control it. Aminosalicylate medications: These are widely regarded as safe to continue throughout pregnancy and while breastfeeding. Corticosteroids: Used when a flare needs to be brought under control quickly, generally at the lowest dose that works and for as short a period as possible. Biologic medications, including tumour necrosis factor inhibitors, vedolizumab, and ustekinumab: Data from large patient registries has not shown a meaningful rise in pregnancy complications or early childhood problems, so most specialists now continue these medications through pregnancy for patients who need them to stay in remission. Thiopurines such as azathioprine and mercaptopurine: Typically continued in patients who are already stable on them, since withdrawing the medication can bring the disease back. Methotrexate: Not used in pregnancy under any circumstance, and stopped several months before conception because of a clearly established risk of birth defects. Janus kinase inhibitors and other newer oral medications: Long-term pregnancy data for these is still limited, so specialists generally switch patients to a better-studied option before they try to conceive. One detail patients often miss: the timing of certain biologic doses in the final trimester can influence which vaccines a newborn should avoid in the first months of life. That’s a detail worth confirming directly with your treating specialist rather than piecing together from general reading. Not sure whether your current treatment plan is appropriate for pregnancy? Get in touch with Dr. Rathod’s team at Fortis Hospital, Mulund, before making any changes on your own. Book Appointment Call now What Happens If Ulcerative Colitis Flares During Pregnancy? Flares don’t pause for pregnancy, and when one happens, it needs proper treatment rather than being written off as a normal part of expecting. This can be tricky, since symptoms like more frequent bowel movements or tiredness overlap with ordinary pregnancy changes, which sometimes delays a proper diagnosis. Any new or worsening rectal bleeding, abdominal pain, or fever during pregnancy deserves prompt attention rather than a wait-and-see approach. Investigations are chosen with pregnancy in mind. A limited flexible sigmoidoscopy is generally considered low-risk when clinically necessary, while a full colonoscopy or scans involving radiation are reserved for situations where the information genuinely cannot be obtained another way.

Acid reflux is among the most common digestive complaints, typically experienced as a burning discomfort after meals. While occasional reflux is harmless, persistent and untreated reflux over several years is recognised as a contributing risk factor for esophageal cancer. Dr. Vipulroy Rathod explains, “Occasional heartburn is rarely a cause for concern. The risk arises from chronic acid reflux that remains unmanaged for years, as the resulting repeated damage to the esophageal lining can gradually lead to serious complications.” Dr. Vipulroy Rathod is a distinguished gastroenterologist in Mumbai, India, with over 30 years of experience and more than 80,000 endoscopic procedures to his credit. A pioneer of diagnostic and interventional endoscopic ultrasound in South Asia, he is widely recognised for detecting esophageal and digestive conditions early, often before symptoms turn serious. His deep expertise in upper GI endoscopy makes him a trusted authority for patients whose reflux needs more than just routine medication. So how does a common complaint like heartburn turn into something serious? Let’s explore the connection step by step. What Is Acid Reflux and How Does It Affect the Esophagus? Acid reflux happens when stomach acid flows backward into the esophagus, the tube that carries food from your mouth to your stomach. A muscular valve called the lower esophageal sphincter normally keeps acid where it belongs. When this valve weakens or relaxes at the wrong time, acid escapes upward and irritates the delicate esophageal lining. That irritation is what causes the familiar burning sensation known as heartburn. An occasional episode is harmless and clears on its own. But when reflux becomes frequent, it is classified as GERD, or gastroesophageal reflux disease. Unlike the stomach, the esophagus has no natural protective coating against acid, so repeated exposure gradually inflames and damages its lining over time. Wondering whether your reflux has crossed from normal to chronic? Let’s dive into what happens when it goes untreated for years. How Can Chronic Acid Reflux Lead to Esophageal Cancer? The link is not immediate, but it is real. When acid repeatedly washes over the esophageal lining for years, the body responds by trying to protect itself. The normal cells lining the esophagus start to change into a different, more acid-resistant type of cell. This adaptation may sound helpful, but it is the first step on a path that can turn dangerous. Over time, these altered cells can become abnormal, a condition doctors call dysplasia. In a small number of people, dysplasia progresses further and develops into esophageal cancer, specifically a type called adenocarcinoma. The key point is that this process unfolds slowly and silently, often over many years, which is exactly why long-standing GERD should never be ignored. The good news is that catching these changes early, before cancer develops, is entirely possible with the right monitoring. But what exactly are these cell changes called, and why do they matter so much? Let’s discuss the condition that sits right in the middle of this journey. What Is Barrett’s Esophagus and Why Does It Matter? Barrett’s esophagus is the name given to that change in the esophageal lining caused by long-term acid exposure. In this condition, the flat cells that normally line the esophagus are replaced by cells similar to those found in the intestine. It develops in a portion of people with chronic GERD and is considered the most significant risk factor for esophageal adenocarcinoma. Here is why it matters. Barrett’s esophagus itself usually causes no extra symptoms, so a person may feel their reflux is under control while the lining quietly continues to change. Most people with Barrett’s never develop cancer, but the condition does raise the risk, which makes regular monitoring essential. Detecting Barrett’s early allows doctors to track it closely and act long before any cancer has a chance to form. This is one of the strongest reasons why persistent reflux deserves a proper look inside with an endoscopy rather than years of guessing from symptoms alone. How do you know if your reflux is heading in this direction? Let’s look at the warning signs worth paying attention to Warning Signs That Acid Reflux May Be Turning Serious Most reflux is manageable, but certain symptoms signal that it is time to see a specialist without delay: Difficulty or pain when swallowing food or liquids A sensation of food getting stuck in the chest or throat Unexplained weight loss with no change in diet Persistent vomiting or vomiting blood Black or tarry stools, which can indicate bleeding A chronic cough, hoarse voice, or sore throat that won’t clear up Heartburn that no longer responds to usual medication Some of these overlap with silent GERD symptoms that don’t feel like typical heartburn at all, which is why they are so easily missed. Noticing any of these signs? Connect with a gastroenterologist before brushing it off as ordinary reflux. Book Appointment Call now Who Is at Higher Risk of Developing Esophageal Cancer? Some people carry a greater risk than others. Knowing where you stand helps you stay ahead of the disease. People with long-standing GERD lasting more than five years Those diagnosed with Barrett’s esophagus Men, who are affected more often than women Adults over the age of 50 Smokers and heavy alcohol users People who are overweight or obese, especially with belly fat Those with a family history of esophageal cancer or Barrett’s People with a diet low in fruits and vegetables How Is the Risk Diagnosed and Monitored? Catching changes early relies on looking directly at the esophagus rather than guessing from symptoms. Here are the main tools doctors use: Upper endoscopy  A thin, flexible tube with a camera is passed into the esophagus to view the lining in real time. It reveals inflammation, Barrett’s changes, and early cancer that symptoms alone cannot show. This is often the moment GERD needs endoscopy rather than just more medicines. Biopsy Small tissue samples are taken during the endoscopy and examined under a microscope. This confirms whether cell changes or dysplasia are present.
