Hepaticodochojejunostomy with afferent limb: CT anatomy.

Hepaticodochojejunostomy with an afferent limb constructed to provide a permanent access route for retrograde biliary dilation has been described. The computed tomographic (CT) scans of 12 patients who had undergone this procedure were reviewed. The appearance of the afferent limb from its position within the subcutaneous tissues to its anastomosis with the biliary tree is described and illustrated. Recognition of the limb as a surgical pathway is important because familiarity with its anatomy will avoid errors in CT interpretation and aid in successful transjejunal catheterization of the bile ducts.
