Background: Choledochal cyst (CDC) is a rare biliary disorder. Surgical treatment consists of CDC excision and biliary-enteric reconstruction. Recently, some institutions have reported successful CDC excision by using minimally invasive techniques. In this study, we report our experience with the laparoscopic management of CDC, with a focus on key operative maneuvers that enhance the likelihood of successful excision.

Methods: Following institutional review board approval, we performed a retrospective review of patients who underwent the laparoscopic excision of CDC and Roux-en-Y hepaticojejunostomy. Between October 2003 and November 2007, we performed laparoscopic CDC excision in 9 patients (8 female and 1 male). Median age was 4 years (range, 8 months to 16 years). There were 7 type I and 2 type IV cysts, according to Todani's classification. Average cyst size was 4.4 cm (range, 1.3–8.5 …
