Endoscopic ultrasound-guided hepaticogastrostomy (EUS-HGS) is associated with less technical success and more adverse events than other kinds of EUS-guided biliary drainage (EUS-BD) [1,2]. Therefore, EUS-HGS is challenging specially for less experienced operators. The major reasons for technical failure are loss of the endoscopic position, migration of guidewire and failure of needle tract dilatation. This article is protected by copyright.
