INTRODUCTION: The incidence of common bile duct (CBD) stones on intraoperative cholangiography (IOC) during laparoscopic cholecystectomy (LC) after preoperative ERCP and successful stone extraction as documented on completion endoscopic cholangiography is approximately 17%. The purpose of this study is to determine the incidence of symptomatic CBD stones after preoperative ERCP and a negative completion endoscopic cholangiogram and an interval LC without an IOC.
METHODS: All patients who underwent preoperative ERCP and interval LC without an IOC from 5/96-12/05 were reviewed under an IRB-approved protocol. Data collected included all radiographic imaging, laboratory values, clinical and pathologic diagnosis and results of preoperative and/or postoperative ERCP and LC without IOC. Follow-up was obtained from inpatient and outpatient medical records and a telephone questionnaire. Statistical significance (p
