The RXi-SITS group saw uterosacral ligament suspension and ovarian vein ligation more commonly performed (both\n                      <jats:italic>p<\/jats:italic>\n                      \u2009&amp;lt;\u20090.05). A multivariable linear regression approach was employed to account for heterogeneity in procedural complexity. Following multivariable adjustment, estimated blood loss, hysterectomy time, and postoperative pain outcomes were comparable between the two surgical approaches. In contrast, multivariable linear regression accounting for concomitant procedures demonstrated that the RXi-SITS approach was independently associated with a significantly prolonged total operative time, with an adjusted mean increase of 21.8\u2005min compared with RSP-vNOTES (B\u2009=\u200921.83; 95% CI: 6.05-37.61;\n                      <jats:italic>p<\/jats:italic>\n                      \u2009=\u20090.007). This is despite unadjusted analyses showing a longer median operative time in the RSP-vNOTES group (160 [IQR 140-194] vs. 151 [120\u2013200] minutes;\n                      <jats:italic>p<\/jats:italic>\n                      \u2009=\u20090.02).\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Discussion<\/jats:title>\n                    <jats:p>Compared with RXi-SITS hysterectomy, RSP-vNOTES hysterectomy demonstrated comparable surgical outcomes, supporting its safety and feasibility across a range of gynecologic procedures. Despite greater procedural complexity in the RSP-vNOTES cohort, the RXi-SITS approach was independently associated with a longer total operative time, suggesting a potential efficiency advantage of RSP-vNOTES in appropriately selected patients.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.3389\/fsurg.2026.1820180","type":"journal-article","created":{"date-parts":[[2026,5,8]],"date-time":"2026-05-08T04:48:25Z","timestamp":1778215705000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":0,"title":["Comparative outcomes of robotic single-port vNOTES versus robotic-Xi assisted single-incision transumbilical surgery for hysterectomy"],"prefix":"10.3389","volume":"13","author":[{"given":"Qiannan","family":"Yang","sequence":"first","affiliation":[{"name":"Division of Minimally Invasive Gynecologic Surgery, Baylor College of Medicine","place":["Houston, TX, United States"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"David","family":"Pasternak","sequence":"additional","affiliation":[{"name":"Division of Minimally Invasive Gynecologic Surgery, Baylor College of Medicine","place":["Houston, TX, United States"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Chunhua","family":"Zhang","sequence":"additional","affiliation":[{"name":"Department of Obstetrics and Gynecology, The Second Affiliated Hospital of Nanjing Medical University","place":["Nanjing, Jiangsu, China"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Xiaoming","family":"Guan","sequence":"additional","affiliation":[{"name":"Division of Minimally Invasive Gynecologic Surgery, Baylor College of Medicine","place":["Houston, TX, United States"]}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1965","published-online":{"date-parts":[[2026,5,8]]},"reference":[{"key":"B1","doi-asserted-by":"publisher","first-page":"14","DOI":"10.1097\/01.sla.0000103020.19595.7d","article-title":"Robotic surgery: a current perspective","volume":"239","author":"Lanfranco","year":"2004","journal-title":"Ann Surg"},{"key":"B2","doi-asserted-by":"publisher","first-page":"1520","DOI":"10.1007\/s11605-022-05319-8","article-title":"Should all minimal access surgery be robot-assisted?
