Abstract

Malignant hilar biliary obstruction (MHBO) is a malignant tumor that causes biliary stenosis and bile drainage problems, which can lead to elevated liver enzymes and jaundice. Endoscopic biliary drainage performed to treat MHBO is essential to improve treatment, survival rate, and patients’ quality of life. However, the biliary drainage in MHBO is technically challenging because of its anatomical complexity, and the successful palliation of cholestasis is less frequent in MHBO than in distal biliary obstruction. In this article, we report a case of proximal stent migration of fully covered self-expandable metal stent following side-by-side deployment in the patient with Klatskin tumor. It is expected that it will be of great help if various preventive methods to reduce stent migration are developed in the future.
