Balloon Enteroscopy, either double or single, is a specialised procedure designed to allow much deeper insertion of the enteroscope into the small intestine. This traditional “blind-spot” is now accessible, thanks to this new technology, which may be carried out through the mouth (antegrade approach) or through the anus (retrograde approach) in the same or separate settings. The special balloons on the scope and an over-tube enable the small intestinal wall to fold up like an accordion, thereby allowing much deeper insertion for diagnosis and therapy, including polyp removal and arresting bleeding. This procedure is commonly employed alongside with Video Capsule Endoscopy (VCE) in the investigation of obscure or mysterious bleeding from the gastrointestinal tract when routine gastroscopy (OGD) and colonoscopy fail to address the problem.
Balloon Enteroscopy is a procedure which requires lots of patience and attention. Depending on the location and nature of the condition, the duration of this procedure can vary quite significantly and is best done under moderate to deep sedation. Besides its routine diagnostic role, single or double balloon enteroscopy may be used to perform special procedures such as ERCP in a surgically altered anatomy which will be challenging when using an ordinary forward-viewing or side-viewing duodenoscope.
This procedure is usually carried out in positions very similar to routine gastroscopy (OGD) or colonoscopy, although you may be asked to change your position from time to time. Occasionally, real time X-rays may be used to allow better visualisation of the entire process. This procedure generally takes longer to perform and it is usually well tolerated. You may experience some bloating or cramps during the procedure which usually goes away shortly. Do discuss with your doctor if you need more information on the subject.
