Diagnosis and surgical treatment of adult congenital choledochal cyst / 中华普通外科杂志

ABSTRACT

Objective To evaluate the diagnosis and surgical treatment of adult congenital choledochal cyst(ACCC). Methods Clinical data of 345 ACCC cases from 1974 to 2007 were analyzed retrospectively. Results There were only 110 patients (31.9%) with typical triad (abdominal pain, palpable mass and jaundice). B-ultrasound, CT, ERCP, PTC and MRCP were methods for diagnosis. Cancer arising from choledochal cysts was found in 19 cases who had undergone internal drainage and its incidence of cholangiocarcinoma is much higher than in the general population. All cases underwent surgical treatment, in which total excision of choledochal cyst and Roux-en-Y hepaticojejunostomy was main operation, 337 cases recovered well and 8 (2. 3%) died. C..ondusions Accurate diagnosis of ACCC was difficult depending on clinical symptoms only. B-ultrasound was the choice of atraumatic diagnosis. All patients with an established diagnosis of ACCC should undergo exploratory laparotomy. Total excision of eholedochal cyst and Roux-en-Y hepaticojejunostomy is most effective treatment for ACCC.
