What happens during an Percutaneous Cholangioscopy procedure?

经皮胆管镜检查是通过在皮肤上做一个小切口来进行的, and advancing a needle into the bile ducts or gallbladder. 将碘化造影剂注入胆管以定位可能引起阻塞的胆结石. 在短时间内(几周)增加引流导管的尺寸后, 然后可以通过经皮胆管镜检查来治疗结石.

为了检查较大的结石，一些患者需要重复经皮胆道镜检查.

较大的结石可以在胆道镜引导下用精确定向激光破碎.

平均需要两次镜检查才能清除推荐十大正规网赌平台的结石. After the stones are removed, 导管将在原位放置几周，以确保胆囊/胆汁系统完好无损，然后取出.

经皮胆道镜检查有哪些风险?

活动性胆管炎(即胆管炎症或感染)患者不应进行经皮胆管镜检查, 因为邻近感染扩散的风险增加，以及血液中细菌引起的全身性疾病.

潜在的并发症包括胆道出血(胆道出血), infection of the biliary track (cholangitis), bacteria in the blood (bacteremia), biliary drainage catheter migration or blockage, and ductal injuries like perforation and bleeding.
