Endoscopic ultrasound‐guided hepaticogastrostomy using a novel covered metallic stent with a fine‐diameter delivery system

Abstract

Endoscopic ultrasound‐guided hepaticogastrostomy (EUS‐HGS) is a useful bile drainage method for the treatment of malignant biliary obstruction^1,2. However, its complication rate is high, and therefore various improvements in both devices and techniques have been made to improve its safety^3‐5. One of the most frequent complications include bile peritonitis due to intraperitoneal bile leakage while exchanging devices during the procedure, and excessive fistula dilation when inserting the stent delivery system.
