Sensitivity analyses by underlying respiratory disease, neoadjuvant chemoradiotherapy or high-volume centers confirmed above findings.</p><p><strong>Conclusion: </strong>This study provides real-world data that TMIE was associated with lower 90-day PPC than OE and HE approaches, especially in patients with underlying respiratory disease or receiving neoadjuvant chemoradiotherapy. These warrant a further review into causes and mechanisms in selected patients, and that quality assurance in delivery of TMIE is probably of major importance. The ideal surgical approach remains unclear, and ongoing trials will provide more evidence within a few years that may clarify the optimum approach to locally advanced esophageal cancers.</p>","PeriodicalId":49229,"journal":{"name":"BMC Surgery","volume":"25 1","pages":"225"},"PeriodicalIF":1.6,"publicationDate":"2025-05-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12096545/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144210049","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
