Objective To investigate the diagnosis and treatment of congenital choledochal cystic dilatation in children. Methods A retrospective review of the clinical features of 26 cases of congenital choledochal cystadentesis admitted in 10 years from 1990 to 1999 in children and the curative effects of different treatment methods were retrospectively summarized. Results 26 cases were diagnosed by B ultrasound and CT. Surgical treatment of 18 cases accounted for 69.2%, cure rate was 100%, conservative treatment of 8 cases accounted for 30.8%, relief of 3 cases accounted for 37.5%, ineffective 4 cases accounted for 50%, death 1 Cases accounted for 12.5%. Conclusions The most effective method to diagnose cystic dilatation in children with congenital choledocholithiasis is abdominal B-mode ultrasound or CT. The most effective treatment is cholecystectomy, jejunal Roux-en-Y anastomosis.
