The use of lumen-apposing metal stents is expanding to include many gastrointestinal benign and malignant causes in selected cases. They may provide an additional treatment option for post-bypass strictures.<\/jats:p>\n          <\/jats:sec>\n          <jats:sec>\n            <jats:title>Methods<\/jats:title>\n            <jats:p>A single centre, retrospective outcomes analysis was performed over a 3-year period of patients with gastrojejunal anastomotic stricture following metabolic bariatric surgery that was treated with a lumen-apposing metal stent. Primary outcomes assessed were clinical success and perforation. Multiple secondary outcomes were assessed regarding safety and endoscopy use.<\/jats:p>\n          <\/jats:sec>\n          <jats:sec>\n            <jats:title>Results<\/jats:title>\n            <jats:p>Of 88 patients that had lumen-apposing metal stents placed, 20 satisfied selection criteria. Eleven patients (55%) had at least one balloon dilatation prior to stent placement. All patients achieved clinical success 20 (100%) with zero perforations. Technical success was achieved in 19 patients (95%). There were four (20%) recurrent strictures, two stent migrations (10%) (with no associated complication), and one in-stent food bolus obstruction (5%). One patient ultimately required surgical revision (5%). Three patients had endoscopy within 30 days of stent removal (15%), and five patients required unplanned endoscopy with the stent in situ (25%).<\/jats:p>\n          <\/jats:sec>\n          <jats:sec>\n            <jats:title>Conclusion<\/jats:title>\n            <jats:p>Lumen-apposing metal stents within our study show potential as another treatment option for gastrojejunal anastomotic stricture following gastric bypass.<\/jats:p>\n          <\/jats:sec>\n          <jats:sec>\n            <jats:title>Graphical Abstract<\/jats:title>\n          <\/jats:sec>","DOI":"10.1007\/s11695-025-07891-9","type":"journal-article","created":{"date-parts":[[2025,6,10]],"date-time":"2025-06-10T06:33:35Z","timestamp":1749537215000},"page":"2755-2761","update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":5,"title":["Lumen Apposing Metal Stents for Gastrojejunal Anastomotic Stricture Following Metabolic Bariatric Surgery"],"prefix":"10.1007","volume":"35","author":[{"given":"Preekesh Suresh","family":"Patel","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Samuel","family":"Reddish","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Andrew","family":"Maurice","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jason","family":"Robertson","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Michael","family":"Booth","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Marius","family":"van Rijnsoever","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"297","published-online":{"date-parts":[[2025,6,10]]},"reference":[{"key":"7891_CR1","doi-asserted-by":"publisher","first-page":"172","DOI":"10.1007\/s11695-018-3500-9","volume":"29","author":"K Almby","year":"2019","unstructured":"Almby K, Edholm D.
