The relationship between juxtapapillary duodenal diverticula and biliary stone disease
Objective:
To assess the relationship between juxtapapillary duodenal diverticula (JDD) and common bile duct stones and biliary stone disease in general.
Design:
A retrospective study.
Methods:
We analysed 1115 patients who underwent consecutive endoscopic retrograde cholangiopancreatography examinations. The patients were subdivided into three groups: the first group (group I; n = 482) had no biliary stone disease, the second one (group II; n = 329) had common bile duct stones, and the third group (group III; n = 304) had biliary stone disease of the gallbladder but without evidence of common bile duct stones. Additionally, the patients were subdivided into age groups of < 50, 50-59, 60-69, 70-79, and > or = 80 years of age. Logistic regression was applied for statistical analysis.
Results:
Juxtapapillary duodenal diverticula were diagnosed in 111 (10.0%) patients. The incidence of JDD was 6.9% in group I, 14.3% in group II and 10.2% in group III. Age was the most dominant influence factor for JDD, common bile duct stones, and biliary stone disease (P < 0.0001). Sex was also a factor, female patients having a higher risk for common bile duct stones (P = 0.01) and biliary stone disease (P < 0.0001). After adjustment for age and sex, JDD was found to have a noticeable, but not statistically significant (P = 0.073), influence on common bile duct stones and no influence on biliary stone disease (P = 0.15).
Conclusion:
Our data support only moderately the existence of a relationship, which had been conjectured in a part of the literature, between JDD and common bile duct stones. No noticeable influence on biliary stone disease was found.
