Juxtapapillary duodenal diverticula: association with biliary stone disease

Abstract

In order to explore the relationship between duodenal diverticula and biliary stone disease, we reviewed 2231 endoscopic retrograde cholangio-pancreatography procedures. We found at least one juxtapapillary diverticulum per 239 patients (10.8%). The occurrence of duodenal diverticula increases with age. Patients with duodenal diverticula were older, had more gallbladder stones, more common bile duct stones, had undergone cholecystectomy more frequently, and experienced more frequently common bile duct stone recurrence after cholecystectomy. We thus confirm an association between the presence of diverticula of the second part of the duodenum, and biliary stone pathology, including gallbladder stones, common bile duct stones, and recurrent stones after cholecystectomy. We discuss the aetiopathogeny of this affection.
