Abstract

The management of ampullary adenomas in familial adenomatous polyposis (FAP) is challenging due to multiple adenomas in the duodenum, history of previous major abdominal surgery, and desmoid lesions. In this study, we aim to define the optimum management for ampullary adenomas, particularly in FAP. This is a retrospective study of all patients with pathology-confirmed ampullary adenomas in M.D. Anderson Cancer Center from 2002 to 2018. Relevant data were extracted, including patient demographics, treatments, outcomes, and adverse events. There were 137 patients with ampullary adenomas who underwent 159 procedures; 95 of the 137 patients had FAP and were placed under close observation, 29 underwent endoscopic ampullectomy, 4 underwent surgical ampullectomy, and 31 underwent panreaticoduodenectomy (PD). In the close observation group, 12.6% progressed to advanced adenoma and subsequently underwent resection. There was no ampullary cancer detected in this group. The endoscopic ampullectomy group had a postprocedure adverse event rate of 10.2%. Eleven patients had residual/recurrent disease after endoscopic ampullectomy, 3 of whom needed surgery. Four patients underwent initial surgical ampullectomy and 2 subsequently needed PD. Pa...Continue Reading
