Objective: To investigate the reasons and prevention of reoperation on congenital choledochal cyst (CCC).
Methods: The sex, age, cyst type, timing and method of operation were analyzed 22 reoperated (CCC) patients who underwent reoperation.
Results: The reoperation rate was 24.4% (22/90). The gender age and cyst type were not related to reoperation rate (P > 0.05). Reoperation rate was correlated with the timing the modality and the manoeuvre of the surgery. The previous emergent surgery incurred higher reoperation rate than that of selective operation (P < 0.01). The reoperation rate was 88.9% in patients previously undergoing CCC extracorporeal drainage, it was 52.4% in group of internal drainage and 5.0% in group previously undergoing CCC resection (P < 0.01).
Conclusions: Congenital choledochal cyst should be treated by surgery in its early stage. Pradent policy should be adopted on the use of PTC and ERCP. Outer drainage was used as the first-aid measure; internal drainage should be abandoned; resection of the cyst with Roux-Y hepaticojejunostomy should be the therapy of choice.
