- Abstract: Since it was first described nearly three decades ago, endoscopic papillectomy (EP) has been utilized as a less invasive, alternative therapy for adenoma of the major duodenal papilla. In this article, we review the recent advances in EP, especially those pertaining to endoscopic ultrasonography (EUS), intraductal ultrasonography (IDUS), and pancreatic stent placement for the prevention of postpapillectomy pancreatitis. Because EUS and IDUS have similar diagnostic accuracies, either modality can be used for the preprocedural evaluation of ampullary tumors. Nevertheless, further technical refinements are required for a more precise evaluation. Given the paucity of data on the usefulness of EUS and/or IDUS during follow-up after EP, a well-designed study is warranted. Furthermore, pancreatic stent placement appears to have a protective effect against postpapillectomy pancreatitis; however, a prospective, randomized, controlled study with a larger number of patients is needed to assess this finding. Moreover, since pancreatic stent placement after EP is not always successful, various novel techniques have been developed to ensure reliable stent placement. Despite the recent advances in EP, further technical refinements and studies are needed to confirm their efficacy.
