Ten children with choledochal cysts were treated at Children's Memorial Hospital in Chicago between 1979 and 1980 and at Henrietta Egleston Hospital for Children or Grady Memorial Hospital in Atlanta between 1980 and 1987. Age at the time of operation ranged from one to 46 months. There were eight girls and two boys with Type I choledochal cysts. One child with a dilated but histologically normal common bile duct underwent a choledochoduodenostomy. The remaining nine patients had excision of the choledochal cyst. Continuity with the GI tract was then re-established with a valved isolated jejunal segment interposed between the common hepatic duct and the duodenum. The valve serves to prevent reflux of enteric contents up into the biliary tract. The short jejunal segment allows bile to drain into the duodenum with minimal stasis; this more closely approximates the natural physiologic state than does a Roux-en-Y reconstruction. There was no mortality, with follow up ranging from six months to over eight years. Two post-operative complications (one anastomotic stricture and one small bowel obstruction) occurred, both in the same patient. There were no anastomotic leaks and no episodes of post-operative cholangitis. All patients are currently free of jaundice and none have signs of portal hypertension. The treatment of choledochal cysts is excision. Biliary tract reconstruction with the valved common hepatico-jejuno-duodenostomy is safe, effective, and physiologically appealing.
