Identification of the ampulla of Vater during oesophageal capsule endoscopy: two heads and viewing speed make a difference.

摘要

We read with great interest the recent study of Selby and Prakoso [1], investigating the abilities of capsule endo-scopy (CE; Pillcam, Given Imaging, Yoqneam, Israel) in the identification of the ampulla of Vater (AoV). AoV identification is considered, by most GE readers, a good surrogate marker of detection of small bowel polyps. This is particularly relevant in the investigations of patients with familial adenomatous polyposis syndromes, which present an increased frequency of periampullary lesions.
