Endoscopic papillectomy: a multicenter, retrospective, nationwide study after the standardization of the technique

Aims Endoscopic papillectomy (EP) is the gold standard of treatment for ampullary adenomas. However, the data supporting EP outcomes derive from multiple retrospective studies, that included procedure mostly performed before 2015, when first guidelines on this technique were published. This is probably why among studies a large variability in patient selection and endoscopic techniques is present, resulting in heterogenous outcomes. Therefore, the aim of our study is to provide data on the efficacy and safety of this technique, by including consecutive patients treated after the standardization of this technique [1] [2] [3] [4] [5] [6].
