The influence of stone size on spontaneous passage of common bile duct stones in patients with acute cholangitis: A retrospective cohort study.

ABSTRACT: Background:The common bile duct (CBD) stones passage in patients with cholangitis was unclear.This study aimed to evaluate the effect on CBD stone sizes and predicting factors on spontaneous passage in patients with cholangitis. Method:The medical records of cholangitis at Her Royal Highness Princess Maha Chakri Sirindhorn Medical Center, Srinakharinwirot University from January 2014 to December 2019 were retrospectively reviewed. Patients with acute cholangitis from CBD stones underwent ERCP in the same admission were enrolled. Result:Of the 96 patients, The rate of spontaneous passage of CBD stones was 19.8%. By univariate analysis, factors significantly associated with a predictor of spontaneous CBD stone passage in patient with cholangitis were single CBD stone (p = 0.001), CBD stone diameter < 5 mm (p < 0.001), and clinical symptom improved before ERCP procedure (p = 0.004). Multivariate logistic regression analyses also revealed that these three factors were significantly associated with spontaneous passage. From ROC curve analysis, stone size of less than 4.85 mm was more likely to pass spontaneously with acceptable sensitivity (81.8%) and specificity (78.9%). Conclusions:CBD stone diameter < 5 mm, single CBD stone and improved clinical symptom before ERCP procedure are key predictors of spontaneous CBD stone passage in cholangitis.
