This study evaluated whether selected endoscopic and histopathologic findings were associated with 30-day outcomes after sleeve gastrectomy, with specific attention to reflux-related events and severity-stratified staple-line leak.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods:<\/jats:title>\n                    <jats:p>We retrospectively analyzed 315 adults who underwent laparoscopic sleeve gastrectomy at a tertiary referral center between June 2016 and December 2019. All patients underwent preoperative esophagogastroduodenoscopy with Sydney-protocol biopsies. Postoperative outcomes were assessed within 30 days. The leak was classified as limited\/minimal when managed with antibiotics alone and as major when invasive intervention or death occurred.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results:<\/jats:title>\n                    <jats:p>Postoperative reflux symptoms occurred in 47 patients (14.9%). Staple-line leak was diagnosed in 13 patients (4.1%) after oral intake using clinical findings, inflammatory markers, and contrast-enhanced computed tomography; routine postoperative day 1 upper gastrointestinal contrast passage studies were normal in all leak patients. Ten leaks were limited\/minimal and resolved with antibiotics alone, whereas 3 patients (0.95%) had major leaks requiring percutaneous\/endoscopic or surgical intervention. Hiatal hernia was associated with postoperative reflux symptoms, and previous upper abdominal surgery was associated with leak. Associations involving endoscopic bile reflux\/possible pyloric dysfunction were exploratory because objective motility testing was unavailable.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions:<\/jats:title>\n                    <jats:p>Preoperative endoscopy may identify selected foregut abnormalities relevant to early outcomes after sleeve gastrectomy, particularly reflux-related anatomy. Leak-related findings should be interpreted cautiously because event numbers were small; severity-stratified reporting provides a more clinically meaningful interpretation than an undifferentiated leak rate.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1177\/10926429261486299","type":"journal-article","created":{"date-parts":[[2026,9,7]],"date-time":"2026-09-07T16:02:10Z","timestamp":1788796930000},"update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":0,"title":["Clinical Relevance of Preoperative Upper Gastrointestinal Endoscopy before Sleeve Gastrectomy: A Retrospective Cohort Study of 30-Day Outcomes"],"prefix":"10.1177","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-5042-6670","authenticated-orcid":false,"given":"Hasan","family":"Ero\u011flu","sequence":"first","affiliation":[{"name":"Department of General Surgery, Izmir City Hospital, University of Health Sciences, Izmir, Turkiye."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ahmed","family":"Taha","sequence":"additional","affiliation":[{"name":"Department of General Surgery, Bursa Yuksek Ihtisas Training and Research Hospital, University of Health Sciences, Bursa, Turkiye."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"\u0130skender Eren","family":"Demirba\u015f","sequence":"additional","affiliation":[{"name":"Kestel State Hospital, Bursa, Turkiye."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"\u00d6zg\u00fcr","family":"\u0130bi\u015f","sequence":"additional","affiliation":[{"name":"Department of General Surgery, Izmir City Hospital, University of Health Sciences, Izmir, Turkiye."}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2026,9,7]]},"reference":[{"key":"e_1_3_7_2_1","unstructured":"1.World Health Organization.
