Abstract
ABSTRACT
Endoscopic ultrasound‐guided hepaticogastrostomy (EUS‐HGS) has become an established, alternative biliary drainage technique for patients with failed or difficult endoscopic retrograde cholangiopancreatography. Stent migration is a particularly serious adverse event of this method. To minimize the risk of migration, preoperative computed tomography (CT) may be used to confirm the distance between the stomach and the liver. We herein report a rare case of stent migration that occurred despite the use of a long stent. Although preoperative CT demonstrated an acceptable hepaticogastric distance, pronounced gastroptosis involving an excessive, downward extension of the stomach during esophagogastroduodenoscopy on postoperative day 3 led to stent migration. This case highlights the importance of recognizing gastroptosis as a potential risk factor of stent migration following EUS‐HGS.
