Small-Bowel Diagnosis in Patients with Familial Adenomatous Polyposis: Comparison of Push Enteroscopy, Capsule Endoscopy, Ileoscopy, and Enteroclysis

BACKGROUND: Conventional upper endoscopy (EGD), EGD with side-view endoscope and ileoscopy are established procedures for endoscopic evaluation of patients with familial adenomatous polyposis (FAP). However, we still have little data on the frequency and relevance of adenomas in those parts of the small bowel which are not accessible to EGD and ileoscopy. Adenomas distal to the duodenum are found more often in FAP patients with known duodenal adenomas. The question is, whether these patients can benefit from additional endoscopic and/or radiographic examinations. METHODS: Between July 2001 and August 2006 we performed comparative small bowel studies with push enteroscopy (PE), capsule endos…
