【 要旨 】 先天性総胆管嚢腫に対する治療は,肝外胆管の切除と胆道再建術が確立した治療法であるが,長期的な術後合併症として,胆管炎,吻合部狭窄,肝内胆管狭窄の遺残,肝内結石の発生,膵石・膵管内蛋白栓などによる膵炎,胆道系悪性腫瘍の発生などの問題点がある.術前術中の肝外胆管の造影と術中の内視鏡的検査を施行し,肝内胆管の狭窄の有無,胆管末端部における膵・胆管合流異常の状況など十分に精査し,初回手術時に,長い将来をもつ小児の術後に合併症を起こさないような手術を施行すべきである.とくに,肝内胆管の狭窄を遺残させないこと,胆管末端部の処置,術後にも癌発生を念頭においた追跡などが要点である.再建法では,肝管空腸Roux-Y吻合術が一般的である.

[ Summary ] Resection of extrahepatic bile ducts, including choledochal cysts and biliary bypasses has become the standard treatment for congenital choledochal cysts. Preoperative studies on the details of the biliary system and the pancreato-biliary junction, and operative cholangiography and endoscopic examinations are mandatory for prevention of late postoperative complications, such as anastomotic strictures, residual intrahepatic bile duct stenosis, intrahepatic cholelithiasis, intrapancreatic duct stones, or cancer of the biliary tract. Intrahepatic bile duct stricture near the hepatic hilum and intrapancreatic portion of the bile duct, and the pancreato-biliary junction, should be thoroughly examined at the time of surgery. Operative procedures to correct intrahepatic duct stenosis and intrapancreatic bile duct stenosis should be performed, dependent on the patient's status. Roux-Y hepatico-jejunostomy is the preferred method of biliary reconstruction. Postoperative follow ups are also important for early diagnosis of bile duct cancer even after the standard procedures for choledochal cysts.
