Treatment of choledochal cyst by excision.
Since 1969 excision of choledochal cyst and establishment of bile drainage by Roux-en-Y hepaticojejunostomy has been performed in 7 children whose ages ranged from 10 mo to 11 yr. In 3 children, the cyst had been treated 5 yr, 4 wk, and 3 wk previously by cystduodenostomy, cystjejunostomy, and cholecystduodenostomy, respectively; further surgery was indicated for biliary obstruction and severe cholangitis. The other four children were not acutely ill. All cysts were located distal to the confluence of the right and left hepatic ducts. The volume of the smallest cyst was 25 ml and the largest 500 ml. In all children a small remnant of distal cyst was not excised to avoid injury to the duodenum and pancreas. In four children a remnant of proximal cyst was left attached to the hepatic duct to allow a large biliary intestinal anastomosis and minimize the possibility of stricture. No serious intraoperative problems were encountered. Prolonged drainage (2-3 wk) from Penrose drain sites in two children were the only postoperative complications. Liver function tests have remained normal in all and no episodes of cholangitis or jaundice have been noted during follow-up (median: 4.5 yr). This experience supports recent reports that indicate that cyst excision is associated with low mortality and morbidity. Cyst excision is preferred over traditional internal drainage procedures because it (A) eliminates a reservoir for bile stasis, (B) removes a mechanism which allows continuous reflux of pancreatic juice into the cyst, and (C) probably prevents the occurrence of bile duct carcinoma which has been noted in 3.0% of patients with choledochal cyst.
