Choledochal cysts are congenital dilations of the biliary tree. The accepted mode of treatment is total excision with hepaticojejunostomy. In this retrospective study, we present our technique and results of laparoscopic choledochal cyst excision.


We retrospectively studied 35 patients who had undergone laparoscopic choledochal cyst excision in our institute from 1996 to 2008. Data about age, gender, type of choledochal cyst, symptoms, surgical technique, conversion rate, morbidity, and mortality were analyzed.


There were Type 1B choledochal cysts in 27 patients (77%) and Type IVA in 8 patients (23%). An anomalous pancreatobiliary junction was found in 40%. Mean operative time was 295 minutes. Total cyst excision could be done in 26 patients. The conversion rate in our series was 8.5%. The overall morbidity rate was 14.3%, the reoperation rate was 8.5%, the mortality rate was 0%, and the incidence of carcinoma was 8.5%.


To minimize the risk of malignancy, total excision of the cyst is ideal, but a small proximal cuff of cyst is retained for small-size ducts to aid in the hepaticojejunostomy anastomosis. A slit on one end of the small ducts will render the anastomosis in an oblique orientation, widening the lumen. Dissecting the posterior cyst wall from the underlying portal vein is the most crucial part of the procedure. Morbidity and mortality rates after laparoscopic management are comparable with published results of the open procedure. Laparoscopic surgery for choledochal cysts is feasible, safe, and even advantageous.
