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.

Frequently Asked Questions
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.
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.
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.
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.
