胆道镜结合气囊导管扩张治疗胆道良性狭窄

BALLOON CATHETER DILATATION COMBINED WITH CHOLEDOCHOSCOPY FOR BENIGN BILIARY STRICTURES

作者应用胆道镜结合气囊导管扩张胆道良性狭窄4例,其中2例经胆总管引流管窦道扩张,1例经皮经肝胆道扩张,1例经皮下空肠亩襻扩张。4例均有胆道手术史及反复发作的胆管炎,除1例拒绝再次扩张者外,其余3例的临床症状或X线表现好转.无扩张后胆道出血、胆管炎恶化或败血症等并发症。

Balloon catheter dilatation guided by flexible choledochoscope was used for intrahepaotic duct stenosis and bilio-enteric anastomostic stenosis in two eace.All the patients had previous operations on biliary tract and symptoms of recurrent cholangitis.The approach was through the drain tract in 2,by percutaneous transhepatic choledochoscopy(PTCS)in 1 and through subcutaneous blind jejunum loop in another.The strictures were dilatcd by filling the balloon with air.All patients except one who refused to repeat dilatation were improved clinically and radiologically,infection proximal to the stenosis was controlled and jaundice was alleviated or disappeared.Balloon catheter dilatation is a simple,safe and effective therapy,when combined with choledochoscopy it is possible to observe stricture,take biopsy and remove gallstones.
