Totally laparoscopic management of choledochal cysts using a four-hole method

Background: Choledochal cyst is a rare benign disease of the biliary tract. However, once diagnosed, it must be excised with the gallbladder because of the risk for cancer developing in the biliary tree, including the gallbladder. This report introduces a new surgical technique for totally laparoscopic excision of choledochal cyst and hepaticojejunostomy using a four-hole method. Methods: Between October 2003 and May 2005, the authors performed totally laparoscopic choledochal cyst excision for 12 patients. All the patients except one were women, and the mean age was 37.3 years (range, 17-62 years). According to the Todani classification, there were five type la cases, four type Ic cases, and three type IV cases. Choledochal cyst excision and Roux-en-Y hepaticojejunostomy were performed laparoscopically using the four-port technique. Results: The mean operation time was 228 min (range, 150-330 min). No operative or postoperative transfusion was required. An oral diet was started on postoperative day 3. The average length of hospital stay was 5.8 days. There was no major complication associated with anastomosis leakage or obstruction. No patient had an adverse response, as determined by clinical or laboratory evaluation during a 2- to 19-month follow-up period. Conclusions: Considering that choledochal cyst is common among young women, who are especially interested in cosmetic results in addition to complete resolution of medical problems, the laparoscopic management of choledochal cyst may be an attractive treatment option.
