Percutaneous transjejunal approaches to the biliary system.

The authors report 10 cases in which various retrograde manipulations in the biliary tract were performed via percutaneous access from the jejunum in patients who had previously undergone Roux-Y biliary surgery. The first cases involved attempted retrograde cholangiography through the jejunal limb in children who had undergone Roux-Y portoenterostomies, followed by cases of percutaneous placement of U tubes and an attempt at percutaneous creation of an hepaticojejunostomy. When a limb from the Roux-Y has been brought to the skin and marked with clips, jejunal puncture is easily performed, is well tolerated by patients, and may be repeated frequently. It also appears that after Roux-Y choledochojejunostomy, the Roux-Y limb is fixed and may be punctured with relative safety. Since access from below is more favorable for intrabiliary manipulations, the transjejunal approach expands the armamentarium of the interventional radiologist in the combined radiologic and surgical management of complex biliary disease.
