Although biliary bypass technique which used jejunum as a conduit is a common procedure in open
technique of hepatobiliary tract surgery, its complicated technique made it is not feasible for laparoscopic
surgery. Before 1960, stomach was used vastly for biliary drainage but late stricture which resulted from too
much tension along suture line made it not much acceptable. The authors report surgical technique of
laparoscopic gastric tube flap for biliary bypass in order to made it practicable for laparoscopic surgery.
