Objectives
Narrative objectives1 Duodenal cancer is one of the extracolonic malignancies which cause death in patients with Familial adenomatous polyposis (FAP). However, the visualization of the ampulla of Vater is not always sufficient with a standard esophagogastroduodenoscopy (EGD) because of limited field of view. Full-spectrum endoscopy (FUSE) provides wide field of view up to 240-degree with double imagers on the front and left side of endoscope tip. The aim of this prospective study was to evaluate the improvement of visualization of the ampulla of Vater in FAP
