Objective:To evaluate the etiology

elinic characteristics

diagnosis and treatments of spontaneous perforation of the bile duct in children. Methods:The clinical data of eight children with spontaneous perforation of the bile duct between 1998 -2006 were analyzed retrospectively. Results:5 of 8 cases were diagnosed bile duct perforativn before operation

all the patients recovered favorably after T-tube and pelvic drainage. 3 children complicated with choledochal cyst were cured afterⅡstage radical operation. Conclusions:the etiology of spontaneous perforation of the bile duct in children is unclear

panereaticobiliary confluence malfunction (PBCM) maybe the main reason. Peritoneocentesis is very important to the diagnosis

which is difficult in child preoperatively. The effective surgical treatments are T-tube and pelvic drainage. The children complicated with PBCM needⅡstage radical operation

and long term follow up are necessary for the children present with spontaneous perforation of the bile duct without PBCM.
