Feasibility of pancreatic duct stent placement before endoscopic submucosal dissection for superficial duodenal neoplasms adjacent to the papilla.

ABSTRACT:

Background

Endoscopic submucosal dissection (ESD) for superficial non-ampullary duodenal epithelial tumors (SNADETs) is technically challenging and is associated with a risk of adverse events, particularly when lesions are located near the major papilla. Pancreatic duct (PD) stent may reduce the risk of post-ESD pancreatitis; however, no standard strategy has been established. This study aimed to evaluate the effectiveness and safety of PD stent placement combined with ESD for SNADETs near the major papilla.

Methods

This was a retrospective study of duodenal ESD after prophylactic PD stent placement in patients with SNADET near the major papilla at a university hospital between March 2014 and September 2023.

Results

Four lesions were located within 5 mm of the major p
