Impact of Juxta-ampullary Duodenal Diverticula on ERCP Complications

Abstract

Background: Juxta-ampullary diverticulum is an acquisitive disorder generally observed in patients over the age of forty years. The purpose of this study is to evaluate the relationship between this abnormality and the incidence of post-ERCP complications.

 Materials and Methods:This was a case-control cross-sectional study that compared post- ERCP complications between patients with juxta-ampullary diverticula and those with no juxta-ampullary diverticula. We classified diverticula based on anatomic locations with respect to the ampulla.

Results: A total of 718 patients referred to our endoscopic ward during one year for ERCP. From these cases, 685 patients underwent ERCP. A total of 47 (6.9%) patients had juxta-ampullary diverticuli, which consisted of type A (25.5%), type B (46.8%), type C (12.8%) and type D (14.9%). The frequency of CBD stones and cholangitis in the case group was significantly more than the control group (p‹0.001). The mean age of patients in the case group was ten years older than patients in the control group (68.04±15.02 vs. 58.25±17.48), which was significant (p‹0.001).

Conclusion: There is an association between juxta-ampullary diverticula and the frequency of CBD stones and post-ERCP complications
