Surgical management of choledochal cysts in adults.
OBJECTIVE
Choledochal cysts are congenital malformations of the pancreatico-biliary system. Some aspects of optimal surgical management of choledochal cysts remain controversial. The purpose of this paper is to present our series of 14 patients with choledochal cysts, analyzing surgical management and long-term results.


METHODS
Between January 1975 and December 2001, 15 adult patients with choledochal cysts were treated at our Department. Sex, age, clinical symptoms, associated diseases, surgical management and postoperative morbidity and mortality were reviewed. Choledochal cysts were classified according to the Alonso-Lej classification with Todani et al.'s, modification, based on radiographic and operative findings.


RESULTS
There were 15 patients, 6 males and 9 females, with an age ranging from 28 to 82 years and a mean age at the time of surgery 58.3 years. Seven patients had a solitary fusiform extrahepatic cyst (Type I), five patients had an extrahepatic supraduodenal diverticulum (Type II), one patient had a choledochocele (Type III), while two patients had a Type IVB cyst. Symptoms were vague and intermittent. Recurrent upper abdominal pain, jaundice, fever, nausea and vomiting were the most common findings, usually occurring in combination. Two patients presented with cholestatic cirrhosis. Five patients had laboratory evidence of hepatocellular dysfunction and two patients had hyperamylasemia. A variety of operations was performed such as cystoduodenostomy, cyst excision and hepaticojejunostomy, cyst excision and choledochoduodenostomy. Postoperative follow-up ranged from 30 months to 12 years in all patients except of two patients who were lost to follow-up.


CONCLUSIONS
Total or partial excision of the choledochal cysts is the optimal treatment because of the lower incidence of postoperative complications and the better survival rate after the operation.
