Objective: To explore the application and technical points of total laparoscopic surgery for congenital choledochal cyst. Methods: The clinical data of 7 patients undergoing laparoscopic surgery for choledochal cyst from August 2011 to December 2012 were retrospectively analyzed. Results: Cyst excision and Roux-en-Y hepato-enteric anastomosis were successfully performed by laparoscopic procedures in 5 patients, and the operative time was 310–400 min, intraoperative blood loss was 50–100 mL and length of postoperative hospital stay was 5–7 d. Follow-up ranged from 3 to 19 months, and no postoperative complications or death occurred. Two patients were converted to open surgery due to severe inflammation of the choledochal cyst or bleeding. Conclusion: Total laparoscopic choledochal cyst excision and Roux-en-Y hepaticojejunostomy is a safe and feasible procedure with the advantages of minimal invasiveness and fast recovery for most cases of choledochal cyst. Excellent laparoscopic skills and teamwork is crucial for surgical success.
