Selection of the surgical approach for reoperation of adult choledochal cysts.

BACKGROUND/PURPOSE: Our purpose was to evaluate the reasons for reoperations and outcomes in patients with choledochal cysts (CCs).

METHODS

The records of patients with CCs who underwent reoperations from 1995 to 2012 were retrospectively reviewed.

RESULTS

Of 165 patients with a mean age of 42.54 ± 14.05 years, 62 had Todani type I (37.6 %), 84 type IV-A (50.9 %), and 19 had unknown type CCs (11.5 %). Previous surgery was internal or external drainage alone in 66.1 % of patients with type I and 23.8 % of patients with type IV-A CCs. Partial cyst excision and Roux-en-Y cyst-jejunostomy or cyst excision and choledochoplasty by jejunal interposition were performed in 16.1 and 11.3 % of patients with type I and IV-A CCs, respectively. Reoperations at our hospital were maximal cyst excision and Roux-en-Y hepaticojejunostomy. Radical cyst excision was achieved in 93.5 % of patients with type I and 44.0 % of patients with type IV-A CCs. With an average follow-up of 48.23 ± 12.30 months, recurrent cholangitis and biliary-enteric anastomotic stenosis occurred in 18 (13.2 %) and 9 patients (6.6 %), respectively. Long-term biliary function was excellent or good in 83.8 % of patients.

CONCLUSIONS

Radical cyst excision and Roux-en-Y hepaticojejunostomy provide good outcomes in patients with CCs.
