ABSTRACT

Background: Periampullary diverticula (DP) are thought to be associated with bile duct stones; they may influence the index of success or failure at endoscopic retrograde cholangiopancreatography (CPE) and may increase the risk of its complications. Aim: Assess the association between DP with bile duct stones and its contribution with the technical success at CPE. Methods: Two hundred and forty five consecutive patients who were undergoing CPE between April 1st and September 23th were prospectively entered into a database. Patients with and without DP were identified and compared. DP prevalence, its association with bile duct stones and with the technical success at CPE, and immediate complications were determined. χ², Student t and Fisher exact test were used. Results: A total of 205 cases were included. DP prevalence was 10.7% (IC 95% 8.6-12.8) Mean age of patients with DP (68 vs. 52 years) (p = 0.001) and the incidence of choledocholithiasis (81% vs. 49%) (p = 0.004) were greater in DP group. There were no significant differences found between DP group and the control group in terms of successful duct cannulation (90% vs. 89%), satisfactory sphincterotomies (95% vs. 93%) or stone extraction (77% vs. 75%). There was an increased frequency of hemorrhage in the DP group (9% vs. 4%) however the difference was no significant. Conclusions: DP is associated with an increased incidence of choledocholithiasis. DP did not cause any major technical difficulties at CPE.
