Objective: To discuss the clinical value of modified laparoscopic lithotomy of common bile duct.
 Methods: Clinical data of 78 patients over the age of 60 with gallstone and choledocholithiasis who underwent modified laparoscopic lithotomy of common bile duct in the past four years were analysed.
 Results: All operations were successful. Ttubes were withdrawn 4 weeks after operation. Of the 78 cases, 77 cases hat no complications and only one case had a small incision infection. All patients recovered without complications after with drawal of Ttube.
