BACKGROUND/AIMS: Results of the surgical management of 60 adults with choledochal cysts at Chang Gung Memorial Hospital Taipei are presented. PATIENTS AND METHODS: All patients were diagnosed and surgically managed during the period between March 1979 and December 1992. There were 47 females and 13 males, with ages ranging from 16 to 81 years (mean age = 31.9 years). Of the total, there were 41 Type I, one Type II, 14 Type IV, and four Type V choledochal cysts classified according to Todani's classification system. The definite surgical procedures were cyst excision and hepatico-jejunostomy in 43 cases in type I and IV diseases, one cyst excision in type II disease, two hepatectomy for type V disease, cyst enterostomy in seven cases, and T-tube choledochocystostomy in seven cases. RESULTS: The operative mortality rate was 3.3% and the complication rate related to the surgical procedure was 20%. Early postoperative complications include wound infection, leakage of anastomosis, acute pancreatitis, septic shock, left pleural effusion, and intra-abdominal abscessing. Reoperations were needed in the early postoperative days in two cases due to hepatico-jejunostomy leakage and intraabdominal abscess formation. Long-term surgical outcome, concerning recurrence of symptoms, was related to the following factors, excluding the factors of surgery: presence of bile duct lithiasis, common channel less than 22 mm, presence of preoperative pancreatitis and acute angle type pancreaticobiliary unions. Only common channel less than 22 mm is statistically significant. The percentage of recurrence of the symptoms after resectional surgery was 32.5% in the long term follow-up period. Most of the cases responded well to an antibiotics treatment. Three of the cases required a second operation or PTCD as well as dilatation to treat the recurrent cholangitis. CONCLUSION: Although the recurrence of symptoms is not uncommon and satisfactory explanation of the analysed factors is still the treatment of choice for adult patients with choledochal cysts.
