The impact of periampullary diverticula on cannulation and adverse events in endoscopic retrograde cholangiopancreatography.

ABSTRACT:

Background

Periampullary diverticulum (PAD) is commonly encountered in endoscopic retrograde cholangiopancreatography (ERCP) procedures.

Objectives

We sought to determine whether PADs are associated with a lower success rate of cannulation and an increased risk of adverse events.

Design

A retrospective cohort study was conducted using prospectively gathered nationwide registry data.

Methods

Using the Swedish registry for gallstone surgery and ERCP, we analyzed a cohort of 66,974 prospectively registered ERCP procedures performed in 2006-2021. The presence of PAD was divided into two groups based on the PAD type: Boix type 1 (the papilla located inside the PAD) and Boix types 2-3 (the papilla located either at the edge of the PAD or immediately adjacent to the P
