Methods: Single-center retrospective review of all patients that underwent rectal resection for primary rectal adenocarcinoma between 2010 and2020. Divided into two groups based on preoperative body mass index (BMI): obese\u2014BMI \u2265 30 kg\/m2, non-obese\u2014BMI &lt; 30 kg\/m2. Results: Total of 513 patients included 100 in the obese group (mean BMI 33.5 kg\/m2, range 30\u201345.6) and 413 in the non-obese group (mean BMI 24.9 kg\/m2, range 15.6\u201329.9, p &lt; 0.001). The groups exhibited a similar age distribution (63.94 and 63.23, p = 0.59) or gender distribution (p = 0.83) between the groups. The obese group had higher conversion rates to open approach (22% versus 11.6%, p = 0.007), and longer surgeries (median 300 min, versus 260 min, p = 0.003), but similar overall postoperative complications (73% versus 64.4%, p = 0.1), 30-day readmission (19% versus 17.4%, p = 0.71), harvested lymph nodes (16 versus 14, p = 0.38), incidence of positive resection margins, 5-year overall survival (94.2% versus 88.7%, p = 0.97), and 5-year disease-free survival (70.4% versus 72%, p = 0.59). Conclusions: Obesity did not affect immediate overall surgical outcomes, surgical pathology quality indexes or long-term oncological outcomes.<\/jats:p>","DOI":"10.3390\/jcm15072693","type":"journal-article","created":{"date-parts":[[2026,4,2]],"date-time":"2026-04-02T11:51:03Z","timestamp":1775130663000},"page":"2693","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["The Impact of Obesity on Operative Outcomes and Long-Term Oncological Outcomes Following Rectal Cancer Surgery: A Retrospective Single-Center Study"],"prefix":"10.3390","volume":"15","author":[{"given":"Dan","family":"Assaf","sequence":"first","affiliation":[{"name":"Division of Surgery, The Chaim Sheba Medical Center, Tel-Hashomer, Ramat Gan 52621, Israel"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Nadav","family":"Elbaz","sequence":"additional","affiliation":[{"name":"Division of Surgery, The Chaim Sheba Medical Center, Tel-Hashomer, Ramat Gan 52621, Israel"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yasmin","family":"Anderson","sequence":"additional","affiliation":[{"name":"Gray Faculty of Medicine, Tel-Aviv University, Tel-Aviv 69978, Israel"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ofir","family":"Gruper","sequence":"additional","affiliation":[{"name":"Division of Surgery, The Chaim Sheba Medical Center, Tel-Hashomer, Ramat Gan 52621, Israel"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3235-2946","authenticated-orcid":false,"given":"Eyal","family":"Mor","sequence":"additional","affiliation":[{"name":"Division of Surgery, The Chaim Sheba Medical Center, Tel-Hashomer, Ramat Gan 52621, Israel"},{"name":"Gray Faculty of Medicine, Tel-Aviv University, Tel-Aviv 69978, Israel"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3701-2307","authenticated-orcid":false,"given":"Michael","family":"Goldenshluger","sequence":"additional","affiliation":[{"name":"Division of Surgery, The Chaim Sheba Medical Center, Tel-Hashomer, Ramat Gan 52621, Israel"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7972-9424","authenticated-orcid":false,"given":"Lior","family":"Segev","sequence":"additional","affiliation":[{"name":"Division of Surgery, The Chaim Sheba Medical Center, Tel-Hashomer, Ramat Gan 52621, Israel"},{"name":"Gray Faculty of Medicine, Tel-Aviv University, Tel-Aviv 69978, Israel"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2026,4,2]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"414","DOI":"10.1038\/s41575-020-0275-y","article-title":"The multidisciplinary management of rectal cancer","volume":"17","author":"Keller","year":"2020","journal-title":"Nat.
