Clipping closure length is a crucial factor for delayed bleeding after endoscopic papillectomy: a retrospective multicenter cohort study.

ABSTRACT:

Background

Bleeding is a serious and frequent adverse event that occurs during and after endoscopic papillectomy (EP). Previous studies have highlighted the effectiveness of preventive clipping closure of the resection site in preventing post-EP bleeding. However, the optimal length of closure remained unclear.

Objectives

We aimed to clarify the optimal clipping length at the post-EP resection site to prevent delayed bleeding.

Design

This study was a multicenter retrospective cohort study.

Methods

We retrospectively analyzed patients who were consecutively admitted to nine high-volume centers for EP between November 2003 and October 2023. The primary outcome was the frequency of delayed bleeding based on the closure length. The optimal closure length rate of th
