回顾性总结大连大学附属中山医院采取经皮肝穿刺胆道造影(PTC)途径渐进性及持续性球囊扩张(GPBD)治疗的7例损伤性胆管狭窄患者的临床资料.其中经PTC途径顺利置入球囊导管5例,2例置管失败者经ERCP辅助下成功放置球囊导管.PTCD及ERCP术后未出现出血、急性胰腺炎等并发症.治疗期间发生球囊损坏2支、球囊移位2次.扩张6个月后胆道造影见狭窄均解除,取出球囊表面无胆泥附着,胆道镜观察见胆管内无胆泥淤积,狭窄处胆管黏膜完整,无充血水肿及纤维素附着.随访5 ～ 27个月无狭窄复发.研究显示经PTC途径的GPBD是治疗损伤性胆管狭窄的一种简单、安全、有效的微创方法.

The clinical data of 7 patients who underwent the treatment of gradual and persistent balloon dilatation (GPBD) by percutaneous transhepatic cholangiography (PTC)for traumatic biliary stricture in Zhongshan Hospital Affiliated to Dalian University were analyzed retrospectively.Balloon catheters were successfully implanted in 5 cases by PTC,and with the help of ERCP in 2 PTC failed cases.There was no bleeding,acute pancreatitis and other complications.Two balloon catheters were damaged and displaced,respectively.All the biliary strictures were relieved.No biliary sludge was attached on the surface of the balloon and in the bile duct.Bile duct mucosa had congestion edema and cellulose attachment.There was no biliary stricture recurrence in the follow-up of 5 to 27 months.This study showed GPBD by PTC was a simple,safe and effective method for treating traumatic biliary strictures.
