Jejunal interposition hepaticoduodenostomy for congenital dilatation of the bile duct (choledochal cyst).

In eight cases of congenital dilatation of the bile duct encountered in our institution during the past 3 years, jejunal interposition hepaticoduodenostomy was performed following resection of the involved bile duct. This procedure has no serious technical difficulties but appears to have some advantages over conventional techniques. The postoperative course of the patients has been favorable for a mean period of 1 year and 5 months up to the present. A further follow-up study is necessary before definite conclusions can be drawn.
