title: Endoscopic ampullectomy in a patient with a duodenal diverticulum. A challenging procedure.
abstract: A 65 year-old male was admitted to the University hospital with obstructive jaundice. Endoscopic examination revealed a grossly abnormal major ampulla, situated at the edge of a large duodenal diverticulum. Biopsy of the ampulla was positive for villous adenoma. We describe the technique utilized to successfully perform an end-bloc endoscopic resection of a major ampulla on a diverticulum.
