Endoscopic Mucosal Resection is a procedure that removes abnormal tissue or early-stage tumours from the lining of the digestive tract through an endoscope, without any cuts or open surgery. It’s used in the oesophagus, stomach, and colon, typically when a lesion is caught early enough that it hasn’t grown beyond the inner mucosal layer. The procedure combines diagnosis and treatment in a single sitting, which is what makes it clinically significant for patients where early-stage disease has been confirmed on prior imaging or endoscopy. According to Dr. Vipulroy Rathod, Gastroenterologist in Mumbai, “EMR has changed what we can offer patients with early GI cancers. A lesion that would have meant major surgery ten years ago can now be removed endoscopically in under an hour, with the patient going home the same day and margins checked on histology within the week.” What Conditions Is EMR Used For? The procedure isn’t limited to one site or one diagnosis. Several GI conditions across different organs meet the criteria for EMR when the lesion is appropriately sized and confined to the mucosa. Barrett’s oesophagus with dysplasia: When Barrett’s progresses to high-grade dysplasia or early adenocarcinoma, EMR removes the affected segment before it invades deeper layers, effectively treating the cancer before it becomes a surgical problem. Early oesophageal and stomach cancers: Lesions confined to the mucosal layer, without lymph node involvement, are suitable candidates. Accurate pre-procedure staging with EUS is what determines whether EMR is appropriate or whether deeper invasion requires a different approach. Large colorectal polyps: Polyps too large or flat for standard snare polypectomy get removed via EMR, often in a piecemeal technique where the tissue is taken out in sections over the lesion’s surface. Submucosal lesions with surface involvement: Certain GI tumours that arise just beneath the mucosa but involve the surface layer can also be addressed endoscopically depending on their characteristics and location. Whether EMR is the right option depends entirely on lesion size, depth, and location factors assessed during workup rather than assumed at the time of the procedure. An endoscopic resection specialist can evaluate the findings and advise whether EMR, ESD, or surgery makes more clinical sense for a given case. How Is EMR Performed and What Should Patients Expect? Most patients arrive with a prior endoscopy report or biopsy result. The procedure itself builds on that workup. Submucosal injection: A fluid solution is injected beneath the lesion to lift it away from the deeper muscle layer. That separation is what makes safe resection possible without perforating the gut wall. Snare resection: A wire loop passed through the endoscope is placed around the lifted tissue and closed. A brief electrical current cuts through the base while sealing blood vessels at the same time, removing the lesion cleanly. Piecemeal removal for larger lesions: Lesions wider than 2 cm are often taken in multiple sections rather than a single pass. Each piece goes to histology separately, and the margins are assessed on the combined specimen. Recovery and follow-up: Patients are monitored for a few hours after the procedure and discharged the same day in most cases. A follow-up endoscopy at 3 to 6 months checks the resection site to confirm complete removal and look for any recurrence at the edges. Understanding which symptoms or findings should prompt investigation in the first place matters as much as knowing the procedure itself.

Dr. Vipulroy Rathod has been performing advanced therapeutic endoscopy at Fortis Hospital Mulund for over 30 years, with EMR forming a core part of his GI cancer practice since the technique became established in India. His EUS experience since 1998 means lesions are staged accurately before any resection decision is made, so patients aren’t taken to EMR when surgery is actually what’s needed, or pushed to surgery when EMR would suffice. Physicians from 35 countries have trained under his endoscopic approach, and referred patients regularly arrive having been told surgery was their only option.

Book Appointment Call now Frequently Asked Questions What is EMR in gastroenterology?  EMR stands for Endoscopic Mucosal Resection, a procedure that removes abnormal tissue or early-stage tumours from the GI tract lining through an endoscope without open surgery. Is EMR a major procedure?  No. EMR is a minimally invasive endoscopic procedure performed under sedation. Most patients are discharged the same day or within 24 hours. What conditions is EMR used to treat?  EMR is used to remove early-stage oesophageal, stomach, and colorectal cancers, large polyps, and precancerous lesions such as Barrett’s oesophagus with dysplasia. What is the difference between EMR and ESD?  EMR removes lesions in pieces using a snare, while ESD cuts beneath the lesion to remove it in one piece, allowing more accurate margin assessment for larger or complex lesions.

Oesophageal cancer grows in the lining of the food pipe and is most commonly linked to chronic acid reflux, tobacco use, and heavy alcohol intake. It presents in two forms: squamous cell carcinoma, which arises in the upper and middle oesophagus, and adenocarcinoma near the lower end, a type that’s become more prevalent as rates of long-term GERD rise. Late diagnosis is the rule rather than the exception here, because early-stage disease rarely causes symptoms distinct enough to trigger investigation. Risk assessment and timely endoscopic evaluation are what close that gap. According to Dr. Vipulroy Rathod, Gastroenterologist in Mumbai, “Most patients assume persistent swallowing difficulty is just acidity acting up. By the time they come in, the window for minimally invasive treatment has often passed. Anyone with chronic reflux or known risk factors should get scoped rather than just medicated.” What Are the Risk Factors for Oesophageal Cancer? This cancer builds over years, not weeks. Certain conditions and habits cause repeated mucosal injury, and it’s that accumulated damage over time that eventually tips into malignancy. Untreated acid reflux: Prolonged GERD causes the lower oesophageal lining to undergo a cellular change called Barrett’s oesophagus. It’s precancerous, and patients who’ve had reflux for years without adequate treatment carry a meaningfully higher adenocarcinoma risk than those whose reflux was managed properly. All forms of tobacco: Squamous cell carcinoma of the upper oesophagus is strongly tied to tobacco use in any form. Cigarettes cause consistent damage, but gutka and pan masala are particularly relevant in India, where chewing tobacco is widespread and often not discussed as a GI cancer risk by treating physicians. Heavy alcohol consumption: Regular heavy drinking erodes the oesophageal mucosa directly. When tobacco and alcohol coexist in the same patient, the combined risk is considerably greater than either factor produces on its own. Obesity: Excess abdominal weight increases intra-abdominal pressure, pushes gastric contents upward, and worsens reflux even in patients who don’t experience classic heartburn. That chronic low-grade acid exposure raises adenocarcinoma risk without the patient ever connecting the two. Patients carrying two or more of these factors shouldn’t wait for a swallowing problem before seeking evaluation. A referral to an oesophageal cancer specialist can clarify whether surveillance endoscopy makes clinical sense before anything turns symptomatic. How Is Oesophageal Cancer Detected? Stage at diagnosis is what determines whether a patient has treatment options or is managing a disease that’s already past the point of cure. These are the investigations that actually make that difference. Upper GI endoscopy: A flexible camera passed through the mouth gives a direct view of the oesophageal lining. Any area that looks abnormal gets biopsied on the spot, in the same sitting. It’s the starting point for any diagnostic workup where oesophageal pathology is suspected. Endoscopic ultrasound (EUS): Unlike external imaging, the EUS probe is placed inside the oesophagus itself, right against the wall being examined. That proximity allows it to assess tumour depth and regional lymph node involvement with a level of accuracy that CT simply can’t match for local staging. NBI endoscopy: Narrow band imaging works by filtering light to highlight the mucosal vessel architecture. Early flat lesions that look completely unremarkable under white-light endoscopy often show clearly abnormal vascular patterns under NBI, which is why high-risk patients shouldn’t be cleared on a standard scope alone. CT and PET-CT scanning: Once a cancer is confirmed endoscopically, cross-sectional imaging establishes whether it has spread beyond the oesophagus to regional nodes, liver, or lungs. That staging information is what determines whether the patient goes to endoscopic resection, surgery, or systemic treatment. Knowing which symptoms warrant urgent investigation matters as much as the investigations themselves. Read more on cancer warning signs to understand which clinical presentations need scoping without delay. Why Choose Dr. Vipulroy Rathod for Oesophageal Cancer? Dr. Vipulroy Rathod has been working in advanced GI endoscopy at Fortis Hospital Mulund for over 30 years. He started performing EUS in 1998, long before the technique became widely available in India, so oesophageal tumours get accurately staged in the same sitting rather than through a separate referral weeks down the line. NBI endoscopy in his practice has identified early oesophageal lesions in patients who’d previously been scoped elsewhere and cleared. Over 35 countries have sent physicians to train under his approach, which reflects the kind of clinical reputation that takes decades to build and doesn’t come from credentials alone. Book your consultation today with one of India’s most experienced specialists for oesophageal endoscopic diagnosis. Book Appointment Call now Frequently Asked Questions What are the main risk factors for oesophageal cancer? Chronic acid reflux, smoking, heavy alcohol use, obesity, and Barrett’s oesophagus are the leading risk factors for oesophageal cancer. How is oesophageal cancer detected early? Upper GI endoscopy with biopsy is the primary detection method. EUS and NBI endoscopy improve accuracy for staging and identifying early flat lesions. Can GERD lead to oesophageal cancer? Yes. Long-standing untreated GERD can cause Barrett’s oesophagus, a precancerous change that raises the risk of adenocarcinoma over time. Is oesophageal cancer treatable if caught early? Yes. Early-stage oesophageal cancer confined to the inner lining is highly treatable through endoscopic procedures such as EMR or ESD without open surgery.

Stomach cancer often produces vague early symptoms that mimic ordinary indigestion, which is why most cases are diagnosed at an advanced stage. Persistent dyspepsia, unexplained weight loss, early satiety, iron deficiency anaemia, and progressive difficulty swallowing are the features that should prompt endoscopy rather than another course of acid suppression. Diagnosis is by upper GI endoscopy with biopsy. Staging adds CT, EUS, and sometimes PET imaging.  According to Dr. Vipulroy Rathod, Gastroenterologist in Mumbai, “Last month a patient came in with a year of indigestion. PPI for ten months. Eradication treatment for H. pylori twice. Nobody scoped him. By the time the diagnosis came, the cancer had grown through the wall. This is not an unusual case. It’s the typical case. In India, stomach cancer in the under-fifties is rising, and the threshold to scope persistent symptoms should be much lower than most doctors apply.” What are the early signs that should prompt evaluation? The early symptoms aren’t specific. Recognising when ordinary symptoms warrant investigation is what separates early-stage diagnosis from late presentation. Iron deficiency anaemia in adults: Men and post-menopausal women with low haemoglobin and low ferritin need both upper and lower endoscopy. Gastric cancer is a recognised cause of chronic occult bleeding in this group and the workup shouldn’t be delayed. Persistent dyspepsia that doesn’t settle on standard PPI treatment, particularly in patients over forty, with risk factors, or with family history of gastric cancer. Continuing empirical management beyond a few weeks delays diagnosis without changing outcomes. Unintentional weight loss: One of the strongest predictors on its own. Any patient losing weight without obvious cause, particularly with upper GI symptoms, needs imaging and endoscopy without delay. Early satiety and post-meal fullness can indicate a tumour reducing gastric capacity or causing obstruction at the antrum or pylorus. Often dismissed as functional dyspepsia in younger patients, which is part of why diagnosis gets delayed. The threshold to investigate should be low in higher-risk patients. Endoscopy services with NBI and chromoendoscopy capability detect early gastric cancers and precursor lesions that standard white-light examination can miss, particularly in patients with chronic atrophic gastritis or intestinal metaplasia. How is stomach cancer diagnosed and staged? Diagnosis is by endoscopy with biopsy. Staging adds imaging, EUS, and sometimes laparoscopy to decide whether the cancer is resectable. Endoscopy with biopsy: The definitive diagnostic test. Multiple biopsies from the lesion and the surrounding mucosa establish the histology, depth pattern, and the extent of mucosal involvement. EUS measures depth of invasion through the gastric wall and identifies regional lymph nodes. The information decides whether early lesions go to endoscopic resection or formal surgery. CT chest, abdomen, and pelvis: Standard staging investigation. Looks for liver metastases, peritoneal disease, and distant lymph nodes that change the treatment plan entirely. Staging laparoscopy in selected cases finds peritoneal metastases that CT missed. Particularly useful in linitis plastica and advanced presentations where occult peritoneal disease is common. Accurate staging changes the treatment plan completely. Read more on Role of endoscopy  for how stomach cancer detection fits into the broader screening strategy for high-risk patients. Why choose Dr. Vipulroy Rathod for stomach cancer assessment? Dr. Vipulroy Rathod has been performing upper GI endoscopy and EUS at Fortis Hospital Mulund since the late 1990s, with the volume of cases that builds pattern recognition for early gastric disease. Most patients arrive after months or years of PPI treatment for symptoms that should have triggered a scope earlier. Recognising the patterns that warrant endoscopy, and then identifying the subtle changes once the scope is in, separates early-stage diagnosis from advanced disease. The harder problem isn’t the diagnosis. It’s that no one suspected cancer in the first place. Indian patients with chronic dyspepsia get treated for years before anyone scopes them. Lowering the threshold to investigate in patients over forty with persistent symptoms, family history, or alarm features is what changes outcomes at scale. Book your consultation today with one of India’s most experienced specialists for stomach cancer assessment and endoscopic diagnosis. Book Appointment Call now Frequently Asked Questions At what age should I be concerned about stomach cancer? Over forty with persistent symptoms or family history. The threshold drops further with H. pylori infection or known chronic gastritis. Can stomach cancer be detected on blood tests? Not reliably enough to base a diagnosis on. Tumour markers like CEA and CA 19-9 lack the sensitivity, and endoscopy with biopsy remains the standard for confirmation. Does H. pylori cause stomach cancer? Yes, chronic H. pylori infection is a major risk factor for gastric adenocarcinoma, particularly the distal type. Eradication reduces but doesn’t eliminate the long-term risk in patients with established mucosal changes. Is stomach cancer curable if found early? Yes,stage one survival exceeds ninety percent with surgery or endoscopic resection, falling sharply with delayed diagnosis. Early endoscopy in symptomatic patients is what makes the difference.

GI tumours can be treated without surgery in selected cases using endoscopic resection, ablation, stenting, and targeted systemic therapy. The approach depends on tumour location, depth of invasion, histology, and whether the intent is curative or palliative. Early-stage cancers and many benign tumours are now managed entirely through the scope, with surgery reserved for cases where endoscopic options aren’t suitable. According to Dr. Vipulroy Rathod, Gastroenterologist in Mumbai, “Surgery used to be the answer for most GI tumours. Now it’s the answer for some. The shift came from accurate staging with EUS, advanced endoscopic resection techniques like ESD, and the ability to ablate or stent lesions through the scope. Patients who would have had gastrectomy or oesophagectomy a decade ago now go home the next day after endoscopic treatment. The trick is choosing the right patient for the right approach.” What endoscopic options exist for GI tumours? The toolkit has expanded considerably. Different techniques serve different tumour types and locations. Endoscopic mucosal resection: Removes small superficial polyps and early cancers by injecting under the lesion and snaring it. Standard for small colorectal polyps and selected early gastric lesions. Submucosal dissection takes larger lesions out in one intact piece using an electrosurgical knife. Used for early gastric cancer, Barrett’s neoplasia, and large colorectal lesions where en bloc removal is essential. Radiofrequency ablation: Burns away dysplastic mucosa in Barrett’s oesophagus and similar conditions. Preserves the underlying organ while eliminating the abnormal tissue layer. Stenting handles malignant obstruction. Self-expanding metal stents reopen blocked oesophagus, stomach outlet, bile duct, or colon in advanced cancer, allowing symptom relief and continued chemotherapy. The choice depends on staging accuracy. Advanced endoscopy services that combine EUS, NBI, and the full range of resection techniques in one centre avoid the gap where patients are sent to surgery because the original assessment didn’t identify them as candidates for endoscopic treatment. When is endoscopic treatment definitive and when is it palliative? The distinction between curative and palliative intent shapes the entire treatment plan. Curative endoscopic resection: Early-stage cancers confined to the mucosa or superficial submucosa, without lymph node involvement, can be cured by complete removal alone. Long-term outcomes match surgery in selected cases. Ablation works for dysplastic lesions in Barrett’s oesophagus and other premalignant conditions. RFA and cryotherapy eliminate abnormal tissue and prevent progression to invasive cancer. Palliative stenting and debulking: Advanced cancers blocking the GI lumen are relieved by stent placement, allowing the patient to eat, swallow, or pass stool while systemic treatment continues. Bridging treatment in patients waiting for surgery or chemotherapy. Endoscopic stenting or biliary drainage stabilises the patient until definitive treatment can be delivered, particularly useful in obstructive jaundice from pancreatic head cancer. Patient selection separates good outcomes from poor ones. Read more on cancer staging for one of the central techniques in modern endoscopic cancer management. Why choose Dr. Vipulroy Rathod for endoscopic tumour treatment? Dr. Vipulroy Rathod has been performing advanced endoscopic resection and ablation at Fortis Hospital Mulund since the late 1990s. EMR. ESD. RFA. Stenting. EUS-guided procedures. Volumes that few centres in India can match under one roof, alongside multidisciplinary input from surgery and oncology that complex cases require. The judgment in tumour management isn’t always about the procedure. It’s about staging accurately, choosing the right approach, and recognising the cases where surgery genuinely is the better option rather than pushing endoscopic treatment that won’t deliver cure. Getting that call right depends on volume, experience, and honest assessment. Book your consultation today with one of India’s most experienced specialists for endoscopic tumor assessment and treatment. Book Appointment Call now Frequently Asked Questions Can all GI cancers be treated endoscopically? No, only early-stage cancers confined to the mucosa or superficial submucosa, without lymph node involvement, are candidates for curative endoscopic resection. Advanced cancers need surgery or systemic treatment. How is staging done before treatment? EUS for depth assessment, CT or MRI for distant spread, biopsy for histology, and sometimes PET scan in selected cases. The staging determines whether endoscopic treatment is appropriate. What is the recovery after endoscopic tumour resection? Most patients go home within twenty-four to forty-eight hours and return to normal activity within a week. Will I need follow-up after endoscopic treatment? Yes, surveillance endoscopy at three to six months initially, then yearly, is standard after endoscopic resection of cancer to detect any recurrence or new lesions at the earliest stage.

Double balloon endoscopy (DBE) is a specialised endoscopic technique that uses two balloons to advance a long scope deep into the small intestine, reaching areas that standard upper GI endoscopy and colonoscopy cannot access. It allows both diagnosis and therapy in the small bowel, including biopsy, bleeding control, polyp removal, and stricture dilatation, in a region previously accessible only through surgery. According to Dr. Vipulroy Rathod, Gastroenterologist in Mumbai, “The small bowel used to be a blind spot. Standard scopes reach the duodenum and the terminal ileum, but the middle three to five metres in between were inaccessible without surgery. DBE changed that. Now we can scope the entire small bowel, take biopsies, treat bleeding, remove polyps, dilate strictures. Conditions that needed laparotomy a generation ago are managed through the scope alone.” What is double balloon endoscopy used for? DBE is used when small bowel pathology is suspected and other tests haven’t confirmed the diagnosis or location. Obscure GI bleeding. The commonest indication. Patients with recurrent bleeding where upper and lower endoscopy have been negative often have a small bowel source that DBE can find and treat in the same session. Small bowel Crohn’s disease for diagnosis, biopsy, and treatment of strictures with balloon dilatation. DBE allows direct visualisation and tissue sampling without surgical access. Small bowel tumours and polyps. Detection and removal of polyps in conditions like Peutz-Jeghers syndrome, neuroendocrine tumours, and isolated small bowel adenomas that capsule endoscopy has identified but couldn’t biopsy. Foreign body retrieval and complications of previous surgery. DBE handles cases involving retained surgical material, anastomotic strictures, and altered anatomy where other approaches have failed. The procedure is technically demanding and takes longer than standard endoscopy. Advanced endoscopy centres with DBE capability and the volume to maintain operator skill are still relatively limited in India, which means access depends on referral patterns and local availability. How is DBE performed and what is recovery like? The procedure uses a long enteroscope with an overtube, both fitted with inflatable balloons that grip the bowel wall during insertion. Antegrade or retrograde approach: DBE can be performed through the mouth to reach the proximal small bowel, or through the rectum to reach the distal small bowel, depending on the suspected lesion location. The scope and overtube are advanced alternately, with the balloons inflated and deflated in sequence to pull the bowel up over the scope rather than pushing the scope through the bowel. Therapeutic interventions during the same procedure: Biopsy, polypectomy, argon plasma coagulation for bleeding, balloon dilatation, and tattooing of lesions for surgical reference can all be performed without a second procedure. Recovery is similar to standard endoscopy, with patients usually going home the same day. Some abdominal discomfort and bloating for twenty-four to forty-eight hours is normal because of air insufflation during the procedure. DBE is one of the more demanding endoscopic procedures and the learning curve is significant. Read more on third space endoscopy for related advanced techniques that have expanded what endoscopy can achieve without surgery. Why choose Dr. Vipulroy Rathod for double balloon endoscopy? Dr. Vipulroy Rathod has been performing advanced enteroscopy and small bowel endoscopic procedures at Fortis Hospital Mulund for over three decades, including DBE for obscure GI bleeding, small bowel polyps, and Crohn’s disease assessment. The training and equipment requirements for DBE are significant, and the volume of small bowel cases handled in the unit allows for proper case selection and procedure planning. The judgment in small bowel endoscopy isn’t only about technical skill. It’s about deciding which patient genuinely needs DBE versus which patient is better served by capsule endoscopy first, surgery, or simply continued observation. Inappropriate use of DBE adds risk without changing management. Proper case selection is what makes the procedure worthwhile. Book your consultation today with one of India’s most experienced specialists for double balloon endoscopy and small bowel disease assessment. Book Appointment Call now Frequently Asked Questions How long does a DBE procedure take? Anywhere from one to three hours depending on the depth of insertion needed and whether therapy is performed. Antegrade approaches are usually faster than retrograde ones. Is DBE safer than surgery for small bowel disease? Yes in most cases. DBE avoids open or laparoscopic surgery and recovery is much faster, though complications like perforation, bleeding, and pancreatitis do occur in a small percentage of cases. What is the difference between DBE and capsule endoscopy? Capsule endoscopy is a diagnostic tool only and produces images but cannot biopsy or treat. DBE allows both visualisation and intervention, which is why it often follows a positive capsule study. Is DBE widely available in India? Limited. Only a small number of centres perform DBE at the volume needed to maintain operator expertise and offer the procedure as a routine service.

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.

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.
