All lesions were located in anatomically challenging areas and ranged in size from\u2009&lt;\u20091\u00a0cm to 5.5\u00a0cm. Four patients underwent submucosal dissection, and one required full-thickness resection. Operative times ranged from 66 to 134\u00a0min. Median console time was 38\u00a0min. No bleeding, conversion, tumor rupture, or spillage occurred. Patients were discharged between postoperative day (POD)-3 and POD-7, with no reoperations, morbidity, or 30-day mortality. Histopathology confirmed R0 resection of one GIST and both melanoma metastases; the NET G2 had positive margins but very low proliferative activity (Ki-67\u2009&lt;\u20090.1%).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>Da Vinci SP robot-assisted transgastric resection is a feasible and safe organ-preserving technique for GEJ and gastric tumors. The platform offers great exposure, stable endoluminal access, and three arms for dissection. This technique complements established endoscopic and laparoscopic procedures. The presented method could also be combined with extraluminal lymphadenectomy. Larger studies with long-term follow-up will define optimal indications and the role of this innovative approach within minimally invasive gastric surgery.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1007\/s00464-026-12829-y","type":"journal-article","created":{"date-parts":[[2026,5,7]],"date-time":"2026-05-07T19:35:09Z","timestamp":1778182509000},"page":"5406-5418","update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["New access to intraluminal gastric pathologies: the SP da Vinci transgastric approach"],"prefix":"10.1007","volume":"40","author":[{"given":"Franziska","family":"Renger","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Alessandro Francesco","family":"Armienti","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yulia","family":"Brecht","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Vladimir J.","family":"Lozanovski","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Edin","family":"Hadzijusufovic","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hauke","family":"Lang","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1859-9213","authenticated-orcid":false,"given":"Peter Philipp","family":"Grimminger","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"297","published-online":{"date-parts":[[2026,5,7]]},"reference":[{"key":"12829_CR1","doi-asserted-by":"publisher","first-page":"1401","DOI":"10.1007\/s00595-023-02694-w","volume":"53","author":"JH Law","year":"2023","unstructured":"Law JH, Han NX, So JBY, Kim G, Shabbir A (2023) Single-incision transgastric resection for gastric gastrointestinal stromal tumors in anatomically challenging locations.
