Type IT, Gadelius Medical K. K., Tokyo, Japan), designed specifically for endoscopic ultrasound-guided hepaticogastrostomy (EUS-HGS), feature a pigtail shape on the gastric side, and migration into the abdominal cavity is particularly rare [1,2] . We experienced a case of intra-abdominal migration of a dedicated PS during EUS-HGS and successfully performed biliary drainage by returning the migrated PSto the stomach through emergency surgery.  \nThe patient was a 91-year-old man, who had previously undergone stomach-partitioning gastrojejunostomy ( ▶ Fig.1) [3] for duodenal cancer. EUS-HGS was performed to treat obstructive jaundice. Due to the suturing of lesser curvature, endoscopic visualization was not possible. Therefore, the PS was deployed under fluoroscopic guidance. The stent was not visible in the stomach, suggesting intraabdominal migration. Computed tomography confirmed that the tip remained in the bile duct, while the gastric side had entered the abdominal cavity. Emergency surgery was performed. The migrated stent was confirmed intraoperatively. The original puncture site had closed naturally, a new fistula site was thus created at the position where the PS was stretched straight. A purse-string suture (3–0 Vicryl, Ethicon, Inc. , New Jersey, USA) was placed, and the stomach was opened using mosquito forceps. The stent was stabilized at the hepatic side and repositioned into the stomach, ligated, and fixed. To promote fistula formation, the gastric serosal muscle and liver parenchyma were sutured. Surgery was completed within 60min, followed by intra-abdominal lavage and drain placement ( ▶Video 1) .  \nObstructive jaundice resolved, and the patient was discharged on postoperative day 11 . Although biliary obstruction  \n▶Fig. 1 Stomach-partitioning gastrojejunostomy. a Schematic illustration showing suturing of the lesser curvature of the gastric body (yellow arrowhead) . The tumor is causing narrowing of the duodenum (*) . b An endoscopic image demonstrating the same finding, with the lesser curvature of the gastric body sutured (yellow arrowhead) .  \nrecurred 49 days later, endoscopic stent exchange via the fistula was successful. In conclusion, when a PS migrates into the abdominal cavity during EUS-HGS and its tip remains in the bile duct, surgical repositioning could correct the migrationstent and allow for biliary drainage. Surgery was completed within 60 minutes. Obstructive jaundice resolved, and the patient was discharged on postoperative day 11 .  \nEndoscopy_UCTN_Code_CPL_ 1AL_ 2AD  \nContributors ʼ Statement  \nMasafumi Watanabe: Conceptualization, Data curation, Formal analysis, Investigation, Project administration, Resources, Validation, Writing – original draft, Writing – review & editing.
