A long-scope technique for difficult intrahepatic bile duct puncture during endoscopic ultrasound-guided hepaticogastrostomy

Takehiko Koga, Yusuke Ishida, Keisuke Matsumoto, Makoto Fukuyama et autres

During endoscopic ultrasound-guided hepaticogastrostomy (EUS-HGS), the intrahepatic bile duct is conventionally punctured from the upper gastric body.[ 1​ ] [ ​2​ ] However, puncture may be challenging because of anatomical conditions.[ 3​ ] [ 4​ ] [ ​5​ ] Herein, we report …

Comparison of EUS-guided treatment and balloon-enteroscopy-assisted endoscopic retrograde cholangiopancreatography for large bile duct stone removal in patients with surgically altered anatomy: A multicenter study

Ryota Sagami, Kiyoyuki Kobayashi, Makoto Hinokuchi, K Takahashi et autres

Background and Objectives: Large bile duct stone removal in patients with surgically altered anatomy (SAA) is technically challenging. Although balloon-enteroscopy-assisted endoscopic retrograde cholangiopancreatography (BE-ERCP) has been widely adopted, EUS-guided treatment (EUS-T) may achieve higher stone removal rates owing to improved device accessibility …

EUS ‐Guided Versus Percutaneous Transhepatic Drainage of Liver Abscesses: A Multicenter Endohepatology Study in Western Japan ( EPIC ‐ LA Study)

Takeshi Ogura, Taira Kuroda, Takanori Matsuura, Jun Kitadai et autres

OBJECTIVE: Percutaneous transhepatic liver abscess drainage (PTAD) and endoscopic ultrasound-guided liver abscess drainage (EUS-LAD) have several limitations. Recently, because of technical improvements in echoendoscope maneuvers, EUS-guided access for the right hepatic lobe has been reported. The aim of this multicenter, retrospective study …

Radial force and wire structure determine the onset of covered self‐expandable metal stent migration in endoscopic ultrasound‐guided hepaticogastrostomy: Measurement of sliding‐resistance force using a porcine model

Takehiko Koga, Hiroshi Yamada, Yusuke Ishida, Naoaki Tsuchiya et autres

BACKGROUND: Self-expandable metal stent (SEMS) migration after endoscopic ultrasound-guided hepaticogastrostomy (EUS-HGS) is a severe complication. The migration risk could be related to the surface friction of SEMS, assumed to be affected by the wire structure and mechanical properties, including radial force (RF); …
