Double Balloon Enteroscopy
Double balloon enteroscopy (DBE), also known as "push-pull enteroscopy" or the "double-bubble", is a new endoscopic technique that allows pan-enteric (complete) examination of the small bowel. DBE is a complimentary technique to small bowel capsule endoscopy. Often abnormalities found at capsule endoscopy are investigated by DBE since DBE can take biopsies or perform treatment which capsule endoscopy cannot do. DBE and capsule endoscopy in combination are two of the most powerful, non-invasive and easy ways to investigate the small bowel. Both tests are associated with minimal discomfort and a very low complication rate.
Double balloon enteroscopy takes between 45 minutes to 2 hours depending on the indication and can be performed under sedation or short acting general anaesthesia for maximum comfort. The procedure is performed through the mouth or the rectum depending on which part of the small bowel needs to be assessed.
During the procedure carbon dioxide is used to insufflate the small bowel which minimizes bloating and tissue biopsies are taken. Following the procedure, patients recover in the Procedural Care Unit and are generally discharged to home the same day.
DBE is very safe and serious side-effects or complications are very rare.
Common side-effects after a DBE may include sore throat, abdominal bloating, nausea, and minor bleeding. These are usually mild and resolve within 12 to 24 hours.
