MRCP assessment of bile stone recurrence after endoscopic choledocholithotomy / 中华普通外科杂志

ABSTRACT

Objective To analyze the related risk factors of choledocholithiasis recurrence after endoscopic sphecterotomy (EST) and choledocholithotomy.Methods A retrospective analysis was made on 734 patients who underwent EST + endoscopic papillary balloon dilation and stones restraction (EPBD) operation with preoperative MRCP imaging and follow-up data from Jan 2012 to Jan 2015.The distribution of MRCP-related signs in patients with and without recurrence of stones was statistically analyzed.Results Preoperative or intraoperative cholecystectomy,peripapillary diverticulum,multiple choledocholithiasis and common bile duct angle were independent risk factors for recurrence of cholelithiasis.Conclusion Small incision EST + EPBD may preserve the function of Oddi sphincter and minimize the trauma to the patient,but there are still some preoperative factors that may affect the recurrence of stones.
