However, postponing ERCP for 1–2 weeks to reduce the risk of lumen-apposing metal stent (LAMS) migration may not be practical in urgent cases such as cholangitis, leading to increased procedural burden. This study aimed to assess the feasibility and safety of a single-session EDGE utilizing a dedicated over-the-scope fixation device.</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> Methods</h3>\u0000 \u0000 <p>A retrospective analysis of prospectively collected data from three referral centers was performed, including consecutive single-session EDGE procedures with the Stentfix device, utilizing only 20 × 10 mm LAMS.

No LAMS migration occurred, and technical success was achieved in 95.0%. Over a median follow-up of 102 days (interquartile range [IQR] 24.8–182), two adverse events were reported (10.0%), comprising postprocedural pain (grade I) and post-ERCP pancreatitis (grade II).</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> Conclusion</h3>\u0000 \u0000 <p>While acknowledging potential contributions from LAMS orientation and stent caliber, our data suggest that utilizing a dedicated over-the-scope stent fixation device may effectively prevent LAMS migration during single-session EDGE without the need for endoscopic suturing.</p>\u0000 </section>\u0000 </div>","PeriodicalId":159,"journal":{"name":"Digestive Endoscopy","volume":"37 2","pages":"176-182"},"PeriodicalIF":5.0,"publicationDate":"2024-07-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141790194","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
