RESUMO
Objective To evaluate the effect of mini-abdominal 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 mini-abdominal incision with choledochoscopy via cystic duct for exploration of the CBD is safe and feasible.
