Abstract:
ObjectiveTo analyze the risk factors of stone recurrence in patients with common bile duct stone after endoscopic retrograde cholangiopancreatography(ERCP).
MethodsA total of 256 patients with common bile duct stone treated with ERCP were selected, and all patients were followed up for more than 6 months.The 17 patients with recurrence and 239 patients without recurrence were divided into the recurrence group and non-recurrence group, respectively.The general conditions, biliary tract conditions, calculus conditions, laboratory tests and surgery method in two groups were retrospectively analyzed.
ResultsThe differences of the age, history of cholecystectomy, diameter of common bile duct, stone size and number of stones between two groups were statistically significant(P < 0.05 to P < 0.01).The results of logistic regression analysis showed that the history of cholecystectomy, large stone diameter and stone number ≥2 were the independent risk factors of stone recurrence after ERCP(P < 0.05 to P < 0.01).
ConclusionsFor patients with older age, history of cholecystectomy, wide diameter of common bile duct, large stone diameter and large number, the preoperative evaluation, intraoperative specification, postoperative prevention and enhanced follow-up must be done to reduce the recurrence of stones.
