Cyctic duct dilation in bile duct exploration by laparoscope combined with choledochoscope

Objective To study the application of cyctic duct dilatiion in bile duct exploration through the cystic duct by laparoscope combined with choledochoscope.Methods LC + laparoscopic transcyctic common bile duct exploration were performed in gallstones combined choledocholithiasis in 70 cases.The dilation of cyctic duct was performed by gas-baloon or metal dilator in 39 cases.The dilation of cyctic duct was not performed in 31 cases.Results There was one case of bile leakage and one case of cystic duct damaging in cystic duct dilation group.One case was found bleeding in abdomen postoperation in non-dilation group.Abdominal drainage was(60 ±11)mL and(55 ±8)mL in dilation group and non-dilation group,respectively.Conclusions The dilation of cyctic duct is simple and safe to create the tunnel for common bile duct exploration through the cystic duct by choledochoscope.
