Endoscopic sleeve gastroplasty (ESG) has been shown to produce effective weight loss and improvement in obesity-related disease. The cost effectiveness of ESG is currently unclear in patients with obesity with and without type 2 diabetes (T2DM).</p></div><div><h3>METHODS</h3><p>A decision analytic model with time horizon of 5 years and lifetime, from a health system's perspective was constructed to compare ESG to no weight loss intervention (no ESG) in patients with obesity aged 35-45 years with a body mass index of ≥30 kg/m² with or without T2DM. Parameters were obtained based on peer-reviewed data. One-way and 2-way sensitivity analyses were performed for variations in T2DM resolution and ESG costs.</p></div><div><h3>RESULTS</h3><p>For the 5-year time horizon in patients with T2DM, ESG produced 4.28 quality-adjusted life years (QALYs) and cost $77,874, compared with 3.99 QALYs and a cost of $73,738 for no ESG, resulting in an incremental cost-effectiveness ratio (ICER) of $13,922 per QALY. For the lifetime horizon, ESG produced 29.57 QALYs and a lifetime cost of $451,261, compared with 26.69 QALYs and a lifetime cost of $493,806 for no ESG, resulting in a negative ICER (ie, cost saving). The 5-year time horizon in patients without T2DM demonstrated that ESG produced 4.42 QALYs, compared with 4.08 QALYs with no ESG, resulting in an ICER of $39,116 per QALY gained. For the lifetime horizon ESG produced 34.21 QALYs, compared with 31.60 QALYs for no ESG, resulting ICER of $4752.</p></div><div><h3>CONCLUSION</h3><p>This cost-effectiveness analysis suggests that ESG is cost effective in 5 years and cost saving over a lifetime for patients with obesity and type 2 diabetes.

In this paper, we propose a framework for assessing a new colonoscopy technology utilizing quality improvement principles applied in procedural and integration assessments. After defining key quality indicators in colonoscopy, we follow the arc of innovation across preprocedural, intraprocedural, and postprocedural advancements in colonoscopy to highlight the process and outcome measures that constitute the procedural assessment. This discussion is followed by case studies in key structure and balance measures that serve to assess the feasibility of integrating novel technology into the endoscopy suite. At both assessment levels, we explore the advent of artificial intelligence in colonoscopy, citing relevant examples in computer-aided detection and computer-aided diagnosis. We highlight innovations that have been successfully adopted into clinical practice alongside technologies that had limited uptake or were otherwise retired from standard of care. In doing so, we illustrate the iterative nature of this process of innovation and technological development.</p></div>","PeriodicalId":36169,"journal":{"name":"Techniques and Innovations in Gastrointestinal Endoscopy","volume":"26 2","pages":"Pages 177-192"},"PeriodicalIF":2.4,"publicationDate":"2024-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2590030724000151/pdfft?md5=71fd0181c3155ca30ac9f8dfa195781a&pid=1-s2.0-S2590030724000151-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140270971","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
