Abstract

Background: Choledocholithiasis is a commonly encountered disease that is associated with various clinical presentations ranging from mild form of biliary colic to severe life-threatening acute cholangitis. Recently, peri-ampullary diverticulum (PAD) has been linked to the development of biliary diseases; however, data regarding its association with the development of acute cholangitis in the setting of choledocholithiasis are scarce. Aims: We aimed to identify predictors, specifically PAD, for the development of acute cholangitis in patients with choledocholithiasis. Methods: We performed a retrospective cross-sectional study of all patients admitted to Galilee Medical Center from 1 January 2010 to 31 December 2019 with different clinical presentations of documented choledocholithiasis including cholangitis, biliary pancreatitis, and biliary colic with abnormal liver enzymes. Results: Overall, 651 patients were included in the final analysis. Among them, 88 patients (13.5%) had choledocholithiasis associated with acute cholangitis (group A), as compared to 563 patients (86.5%) without acute cholangitis (group B). The average ages in groups A and B were 77.8 ± 13.6 and 62.4 ± 20.4 years, respectively (P < 0.0001). The rate of PAD was significantly higher in group A as compared to group B (35.2% vs. 19%, P = 0.0002). However, the rate of smoking, chronic liver diseases, hemolytic anemia, and post-cholecystectomy status were not different between the groups (P = 0.3, P = 0.3, P = 0.2, and P = 0.3), respectively. On univariate analysis, age (OR 1.05, P < 0.0001) and PAD (OR 2.32, P = 0.0006) were significantly associated with acute cholangitis. On multivariate logistic regression analysis, the effects of age and PAD were preserved (OR 1.05, 95% CI 1.03–1.07, P < 0.0001 and OR 1.64, 95% CI 1.02–2.72, P = 0.049), respectively. Conclusion: PAD showed a significant association with the development of acute cholangitis among patients with choledocholithiasis. Identification of gallbladder and biliary stones in patients with PAD is of paramount importance since early diagnosis and treatment might prevent further life-threatening complications.
