To study and analyze the related risk factors associated with stone recurrence after endoscopic retrograde cholangiopancreatography (ERCP) in patients with common bile duct stones (CBDS).

From March 2014 to March 2017 in the 6th People's Hospital of Shanghai, two hundred patients treated with cholangiopancreatography were divided into two groups, with postoperative CBDS recurrence in 86 patients as the observation group, no postoperative CBDS recurrence in 114 patients as the control group. Univariate analysis was performed for two groups, and multivariate logistic regression analysis was used to screen out the risk factors.

Age, duration, the diameter of the common bile duct, biliary surgery, biliary stricture, diverticula, stone size (≥10 mm), the number of stones (more than 2) in the observation group were significantly higher than that in the control group, respectively, the differences were statistically significant (all P<0.05). Multivariate analysis showed that age, history of biliary surgery, peripapillary diverticulum, the number of stones more than 2 pieces, common bile duct diameter, and stone size (diameter≥10 mm) were the independent risk factors of postoperative recurrence in CBDS patients (P<0.05).

Age, history of biliary tract surgery, combined diverticula, more than 2 pieces of stones, and common bile duct diameter more than 10 mm are the independent risk factors of the recurrence of post ERCP in CBDS.
