If you have small intestine problems, such as bleeding, narrowing of the intestine, abnormal tissue, polyps or tumors, your doctor may recommend deep enteroscopy.
What to Expect When You Have Deep Enteroscopy
Deep enteroscopy is also known as balloon-assisted enteroscopy. During the procedure, a long endoscopy (a flexible tube with a light and camera attached to it) is inserted into the mouth (antegrade) or rectum (retrograde) and moves through the body to the small intestine where it inflates and deflates to help view the gastrointestinal (GI) tract.
A deep enteroscopy may take several hours. Some patients may receive general anesthesia, while others may require moderate sedation. During the procedure, your doctor may also use an X-ray [link] to view your GI tract.
