Gastrointestinal bleeding originating from the small bowel is difficult to diagnose and treat because the small bowel is difficult to see and reach. Balloon assisted enteroscopy (BAE) is a new enteroscopy methods that allow examination of the small bowel and allows for diagnosis and treatment of bleeding originating from this part of the intestine. Unfortunately, BAE is unsuccessful in identifying the cause of bleeding in 40-50% of patients. This may be due to limited visualization of the small bowel lining during conventional endoscopy. One way to improve visualization of the small bowel lining is by adding a transparent plastic cap to the end of the endoscope (camera), which allows the endoscope to see around sharp turned and behind folds in the small bowel.
