Frank G. J. Kallenberg et al. Cap-assisted forward-viewing endoscopy to visualize the ampulla of Vater and the duodenum in patients with familial adenomatous polyposis

This proof-of-concept study demonstrated that cap-assisted forward-viewing endoscopy can be used effectively and safely to visualize both the duodenum and the ampulla of Vater in patients with familial adenomatous polyposis, thus challenging the concept that side-viewing endoscopy is mandatory for surveillance in these patients. This practice might reduce the burden, time, risks, and costs of an additional side-viewing endoscopy.
