TI  - A pilot study of Spring Stopper Stents: Novel partially covered self-expandable 
      metallic stents with anti-migration properties for EUS-guided 
      hepaticogastrostomy.

AB  - BACKGROUND AND OBJECTIVES: EUS-guided hepaticogastrostomy (EUS-HGS) is an 
      effective salvage procedure when conventional endoscopic transpapillary biliary 
      drainage is difficult or fails. However, the risk of stent migration into the 
      abdominal cavity has not been resolved completely. In this study, we evaluated a 
      newly developed partially covered self-expandable metallic stent (PC-SEMS) that 
      has a spring-like anchoring function on the gastric side. METHODS: This 
      retrospective pilot study took place at four referral centers in Japan between 
      October 2019 and November 2020. We enrolled 37 cases consecutively who underwent 
      EUS-HGS for unresectable malignant biliary obstruction. RESULTS: The rates of 
      technical and clinical success were 97.3% and 89.2%, respectively. Technical 
      failures included one case in which the stent was dislocated during the removal 
      of the delivery system, requiring additional EUS-HGS on another branch. Early 
      adverse events (AEs) were observed in four patients (10.8%): two with mild 
      peritonitis (5.4%) and one each (2.7%) with fever and bleeding. No late AEs were 
      observed during the mean follow-up period of 5.1 months. All recurrent biliary 
      obstructions (RBOs) were stent occlusions (29.7%). The median cumulative time to 
      RBO was 7.1 months (95% confidence interval, 4.3 to not available). Although 
      stent migration in which the stopper was in contact with the gastric wall on 
      follow-up computed tomography was observed in six patients (16.2%), no migration 
      was observed. CONCLUSIONS: The newly developed PC-SEMS is feasible and safe for 
      the EUS-HGS procedure. The spring-like anchoring function on the gastric side is 
      an effective anchor preventing migration.
