Abstract:Objective:To evaluate the effect of miniabdominal incision for choledochoscopy via cystic duct in exploration of the common bile duct (CBD). Methods :The right subcostal incision was 4-6 cm in length. Choledochoscopy via cystic duct stump for exploration and extraction of CBD stones was done in 135 cases. Results:The CBD stone was removed in 109 of 135 patients (80.7%). The CBD exploration was negative in 26 cases (19.3%) and retained CBD stones occurred in 4 cases (3.0%). One case （0.7%）had intraoperative injury of common bile duct, 2 cases (1.5%) had tear of cystic duct stump, and 2 cases (1.5%) had biliary leakage, all the 5 cases were recovered after treatment. Conclusions:The miniabdominal incision with choledochoscopy via cystic duct for exploration of the CBD is safe and feasible.
