The modified laparoscopic transcystic biliary drainage which we developed in the treatment of cholecystocholedocholithiasis has some advantages over conventional techniques.
Here, a 7-Fr triple-lumen 30-cm central venous catheter was adopted to replace conventional 5-Fr ureteral catheter, which extended the function of the C-tube.
Then we developed a continued suture and circling manner by the V-Loc closure device, which simultaneously covered and anchored the C-tube.
Theoretically, this modified laparoscopic transcystic drainage not only provide safe and effective bile duct drainage, but also provide a convenient access of treatment for postoperatively retained bile duct stones, which may expand the indication of initially laparoscopic operation in the management of cholecysto-choledocholithiasis.
