Percutaneous transhepatic cholangiography (PTHC los yog PTC) los yog percutaneous cholangiography yog siv los ua kom pom lub cev ntawm lub plab biliary siv cov tswv yim radiographic. Tus neeg sawv cev sib txawv yog txhaj rau hauv cov kua tsib ntawm lub siab thiab X-rays raug coj mus.
Yog tias endoscopic retrograde cholangiopancreatography (ERCP) ua tsis tiav, tsob ntoo biliary tuaj yeem nkag mus. Qhov kev zov me nyuam tau tshaj tawm thawj zaug hauv 1937 thiab tau nrov hauv xyoo 1952.

Tsis tas li ntawd, tus kheej-dilating hlau stents yuav muab tso rau hauv malignant biliary strictures rau palliative kua. Percutaneous qhov chaw ntawm cov hlau stents tso cai rau xaiv ntau qhov chaw ntawm cov hlau stents thaum kho ERCP tsis ua tiav thiab lub cev hloov pauv los tiv thaiv kev sib cais endoscopic ntawm ib feem ntawm cov kua tsib uas nkag mus rau hauv duodenum lossis lub siab los ntawm cov kua dej.
Biliary angiography hauv cov kua dej hauv biliary yog hu ua perioperative lossis thawj cholangiography, thiab thaum ua tiav tom qab hauv tib lub kua dej, theem nrab cholangiography.
