Feasibility of endoscopic papillectomy in early stage ampulla of Vater cancer.

Background And Aim: Although endoscopic papillectomy has been attempted in early stage ampullary cancer (pTis, T1), its curative role and indications remain uncertain. The present study was designed to assess the factors that predict malignancy and lymph node metastasis and to suggest potential indications for endoscopic papillectomy by analyzing clinicopathological data.

Methods: We performed a retrospective analysis of clinical and histopathological data of 216 patients with ampullary cancer between 1991 and 2006.
