Abstract

Acute obstructive cholangitis due to the migration of necrotized tumor fragment(s) has been rarely reported after transarterial chemoembolization (TACE). We report an unusual case of it, which was demonstrated by computed tomography (CT) and endoscopic retrograde cholangiography. We suggest that in the setting of acute biliary obstruction after TACE with a CT-demonstrated new intraductal soft tissue lesion with or without a radi- opaque portion, along with no or less visualization of a previous tumor located inside or near the duct, the possibility of intraductal migration of a necrotic tumor fragment should be considered. Both clinicians and radiologists should become familiar with this condition because it may be ignored or misinterpreted as biliary calculi.

坏死性肝细胞癌导管内转移：化疗栓塞后梗阻性胆管炎的可能原因

经动脉化疗栓塞（TACE）后，坏死肿瘤碎片迁移引起的急性梗阻性胆管炎很少报道。我们报告了一个不寻常的病例，通过计算机断层扫描（CT）和内窥镜逆行胆管造影证实了这一点。我们建议，在TACE后急性胆道梗阻的情况下，CT显示新的导管内软组织病变，有或没有放射不透明部分，并且没有或很少看到以前位于导管内或附近的肿瘤，应考虑坏死肿瘤碎片在导管内移行的可能性。临床医生和放射科医生都应该熟悉这种情况，因为它可能被忽视或误解为胆道结石。

期刊介绍： IJGII (pISSN 2636-0004, eISSN 2636-0012) was published four times a year on the last day of January, April, July, and October, which has effected from January 1 in 2019. This Journal was first published biannually on June and December, beginning in December 2012 under the title ‘Gastrointestinal Intervention’ (former pISSN 2213-1795, eISSN 2213-1809) and was changed to be published three times a year from 2016. Commencing with the January 2019 issue, the Journal was renamed ‘International Journal of Gastrointestinal Intervention’. As the official journal of the Society of Gastrointestinal Intervention (SGI), International Journal of Gastrointestinal Intervention (IJGII) delivers original, peer-reviewed articles for gastroenterologists, interventional radiologists, surgeons, gastrointestinal oncologists, nurses and technicians who need current and reliable information on the interventional treatment of gastrointestinal and hepatopancreaticobiliary diseases. Regular features also include ‘state-of-the-art’ review articles by leading authorities throughout the world. IJGII will become an international forum for the description and discussion of the various aspects of interventional radiology, endoscopy and minimally invasive surgery.
