Abstract:
Objective To investigate the risk factors for recurrence of common bile duct(CBD) stones after treatment with ERCP.Methods Data of patients who underwent ERCP from July 2007 to Decem-ber 2011 for CBD stones were collected.The risk factors for recurrence including gender,age,history of chole-cystectomy,diameter of CBD,number of stones,gallstones,papillary diverticulum,lithotripsy and endoscopic nasobiliary drainage were assessed by univariate analysis and multivariate logistic regression analysis.Follow-up was conducted to retrospectively investigate stone recurrence rate.Results A total of 1 699 patients were fol-lowed up with a mean duration of 55.6 months.There were 134(7.9%)patients with stone recurrence over a mean duration of 24 months.The univariate analysis showed that diameter of CBD≥13 mm,history of cholecys-tectomy,number of stones≥2,lithotripsy were related to CBD stone recurrence.Multivariate analysis showed di-ameter of CBD≥13 mm(OR =1.607,95%CI:1.051-2.456,P =0.028),history of cholecystectomy(OR =7.101,95%CI:4.539-11.108,P =0.001),gallstones(OR =2.441,95%CI:1.417-4.206,P =0.001)were in-dependent risk factors for recurrence of CBD stones.Conclusion Diameter of CBD≥13 mm,history of chole-cystectomy,gallstones are independent risk factors for recurrence of CBD stones.
