Patients with cholecystolithiasis secondary to common bile duct stones requiring surgical treatment during a 3-year period from 2022-6-1 to 2025-3-31 were enrolled in this non-randomized controlled clinical trial. Preoperative diameter of the middle common bile duct was determined by magnetic resonance cholangiography (MRCP) or B-ultrasound measurement. The actual treatment plan of the patients was recorded, including LERV treatment and ERCP+LC treatment. The baseline data and the success rate of stone removal, operation time, postoperative stone residual rate, complication rate, length of hospital stay and hospitalization cost were recorded for observation and follow-up. To determine whether modified LERV can be used as the preferred routine treatment for choledocholithiasis secondary to gallbladder stones.
This study intends to explore the success rate and clinical efficacy of modified LERV in the treatment of patients with non-dilated common bile duct (internal diameter ≤10mm) through a non-randomized controlled clinical trial, and to clarify whether modified LERV can be used as the preferred routine treatment for choledocholithiasis secondary to gallbladder stones.
