Limited data exist on redo G-POEM safety and effectiveness. We describe outcomes of patients undergoing repeat G-POEM for refractory gastroparesis. <b><i>Methods:</i></b> A retrospective review of patients who underwent redo G-POEM at our center from 2008 to 2024. Data included demographics, gastroparesis etiology, previous treatments, Gastroparesis Cardinal Symptom Index (GCSI), gastric emptying studies (GES), and clinical outcomes. <b><i>Results:</i></b> Three patients (mean age at first G-POEM 52.3 ± 19 years) were identified. All procedures were technically successful, and all 3 patients survived to discharge without major complications. Patient A (sarcoidosis-induced gastroparesis) had transient symptomatic improvement after the first G-POEM, but symptoms deteriorated the following year. GES showed initial improvement (26% to 14% 4-hour retention) but returned to baseline (26%) after the second G-POEM. She ultimately required jejunostomy tube placement. Patient B (idiopathic gastroparesis) with a history of renal transplant showed no objective improvement in GES after either procedure (40% to 41% 4-hour retention) and remained noncompliant with dietary recommendations. He died at age 35 from cardiac arrhythmia 2 years after the second G-POEM. Patient C (postsurgical gastroparesis) had improvement in GES after the first G-POEM (88% to 53% 4-hour retention) but then deteriorated to 73% despite symptomatic improvement. After symptom recurrence, redo G-POEM provided an excellent symptomatic response, but she remained total parenteral nutrition-dependent until death 4 years later. <b><i>Conclusion:</i></b> While redo G-POEM is technically feasible and safe, our case series demonstrates poor long-term clinical outcomes across different gastroparesis etiologies. All 3 patients experienced treatment failure, with 2 requiring permanent nutritional support and 1 showing a lack of symptomatic response. These findings may suggest limited utility of redo G-POEM and highlight the need for careful patient selection.</p>","PeriodicalId":50166,"journal":{"name":"Journal of Laparoendoscopic & Advanced Surgical Techniques","volume":" ","pages":""},"PeriodicalIF":1.1,"publicationDate":"2025-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145202041","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
