title: Choledochal duct cyst: resection with physiologic reconstruction.
abstract: BACKGROUND
  The accepted surgical treatment of choledochal duct cyst is complete excision and enteric drainage through an intestinal conduit. Peptic ulceration and fat malabsorption have been reported after Roux-en-Y reconstruction. Such long-term complications may be avoided by a technique that simulates normal physiology.
  
  
  METHODS
  Twenty-one patients have undergone resection of a choledochal duct cyst in the past 12 1/2 years. The pathologic duct is resected to the level of normal mucosa. A short segment of jejunum with a intussusception valve (1.5 to 2 cm) is interposed between the common hepatic duct and the duodenum. The medical records and all radiographs of each patient were reviewed. Eighteen children were reexamined or the parents were contacted by phone.
  
  
  RESULTS
  Twenty of 21 patients recovered without major perioperative complications. Twelve of them are well and have no symptoms at 3 to 12+ years (mean, 6 years) after operation. Four children are currently well 6 to 19 months after operation. Three children were well when lost to follow-up. Two patients have radiographic evidence of incompetence of the interposition valve. One of these, who initially underwent operation at 9 months of age, was reexplored at 10 months and at 10 years for a stricture at the hepaticojejunal anastomosis. The other, a 7-year-old girl who was admitted with jaundice and pancreatitis, has had episodic abdominal pain for 7 years after operation but is well.
  
  
  CONCLUSIONS
  The valved jejunal interposition hepaticoduodenostomy offers superior biliary reconstruction after excision of a choledochal duct cyst. Normal physiology is simulated, with bile draining directly into the duodenum. A short conduit prevents stasis, and biliary reflux is minimized with the addition of an intussusception valve.
