Endoscopic Management of Ampullary Adenomas in Familial Adenomatous Polyposis Syndrome: A Systematic Review with Pooled Analysis.

Background: Endoscopic papillectomy is a viable therapy in ampullary lesions. Prior studies have reported on outcomes of sporadic ampullary lesions, and only small cohort studies have reported outcomes associated with familial adenomatous polyposis (FAP) syndrome.

Aims: We performed a systematic review with pooled analysis to assess the safety and efficacy of EP for treating ampullary adenomas in FAP.
