Introduction:

In endoscopic retrograde cholangiopancreatography (ERCP), the prevalence of duodenal diverticulum (DD) is approximately 5-30%, associated with difficult cannulation and a greater number of complications.

Objective:

Describe the prevalence of DD in patients undergoing ERCP at Regional Hospital #1 Dr. Carlos MacGregor Sánchez Navarro. Secondary objectives: report the most common type of diverticulum, correlation between difficult, successful or failed cannulation and diverticulum, as well as associated complications.

Method:

An ambispective, cross-sectional study was carried out, including patients undergoing ERCP in the Endoscopy Department of Regional Hospital #1 Dr. Carlos MacGregor Sánchez Navarro, from the period from January 2022 to May 2024, when analyzing patients with periampullary diverticula, and the relationship with successful or failed ERCP and complications associated with it.

Results:

A total of 1,327 studies carried out in the previously described period were included, finding a DD prevalence of 8.6%; 62.3% were women, with a mean age of 71.1 years, the most frequent diverticulum was type III (38.6%). An association was found between failed ERCP and type IA diverticulum (p = 0.003), in the correlation analysis a coefficient r: 0.036 was obtained (p = 0.006), a strong association; however, for the type of diverticulum and difficult cannulation there was no association (p = 0.224) or correlation (p = 0.400).

Conclusions:

The prevalence of duodenal diverticulum agrees with that reported in the literature, a strong association was found between failed ERCP and type IA diverticulum, but no association or correlation between type of diverticulum and difficult cannulation or complications.
