A postoperative follow-up study, through the subcutaneouslyplaced afferent loop of a choledocho-jejunostomy by retrograde cholangiography and/or choledochoscopy in 116 patients with intrahepatic lithiasis, was made. The retained stones, worms, ductal strictures, or suppurative cholangitis were found in 41 cases over a period of one month to six years postoperatively. All these conditions required further management and some even emergency intervention. The patients were all treated successfully by a Dormia basket or other instruments through this conduit with exception of four failures, the overall success rate was 90%. It is suggested that this type of Roux-en-y choledocho-jejunostomy is recommended in the cases with intrahepatic lithiasis which can provide a permanent access from outside to thebiliary tree and appropriate instruments can be passed through this route for diagnostic and therapeutic interventions such as postoperative cholangiography, retained stones removal, and biliary drainage. We believe this route has some advantages over the T-tube tract for non- operative management of intrahepatic residual lesions.
