Laparoscope-assisted minimally invasive treatment for choledochal cyst

Abstract

The principle of treatment of choledochal cysts is total cyst excision with hepaticojejunostomy because of the high rate of associated malignancy of the biliary system. The authors used a minimally invasive laparoscopic procedure to treat a patient with nonmalignant choledochal cyst. Although a large median laparotomy is usually used for cyst excision and hepaticoenterostomy, laparoscope-assisted total cystectomy and hepaticojejunostomy were performed with minimal skin incision. To avoid gas embolism during dissection around the hepatic hilus the surgical procedure was divided into two stages: CO2 insufflation and abdominal lifting without pneumoperitoneum. This combination of procedures was as safe and technically adequate as conventional surgery. No abnormalities were observed in liver function, and the patient could sit up in bed the first day postoperatively. Thirteen days after surgery, he was discharged from the hospital uneventfully.
