title: Procedures for congenital choledochal cysts and curative effect analysis in adults.
abstract: OBJECTIVE
  To evaluate the procedures and timing of operation as well as long-term postoperative effect of congenital choledochal cysts (CCC) in adults.
  
  
  METHODS
  The procedures and timing of operation, effective rate, re-operation rate and incidence of carcinoma after operation for 70 adult patients with CCC from January 1980 to June 1999 were analyzed retrospectively.
  
  
  RESULTS
  The re-operation rate of external drainage was 86% (6/7). The effective rate of internal drainage was significantly lower than that of cyst resection (3/10 vs 45/49, chi2=20.94, P<0.001). The re-operation rate and incidence of carcinoma of internal drainage were higher than those of cyst resection (5/10 vs 3/49, chi2=13.64, P<0.001 and 3/10 vs 3/49, chi2=5.18, P<0.025). The reoperation rate of emergency surgery was higher than that of selective operation (8/10 vs 6/56, chi2=24.37, P<0.001).
  
  
  CONCLUSIONS
  External drainage should be the first-aid measure and the therapy of choice on emergency basis. Internal drainage should never be attempted. Cyst resection with Roux-en-Y hepaticojejunostomy is recommended as the treatment of choice in selective operation.
