The da Vinci robotic system offers stable 3D vision, near\u2010infrared fluorescence imaging, and articulating wrist movements, making it suitable for performing reduced\u2010ports robotic pylorus\u2010preserving gastrectomy (RP\u2010RPPG).

Electronic medical records were retrospectively reviewed for operative time, estimated blood loss (EBL), retrieved number of lymph nodes, postoperative hospital course, and early complications. Learning curve using operation time was analyzed through cumulative sum (CUSUM) and segmental analysis methods.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Among the 79 patients included, the median operation time was 175.0 (66.0) minutes, and estimated blood loss was 10.0 (25.0) mL. Early complications occurred in 6 patients (7.6%), but all were managed conservatively without needing invasive intervention. Among them, delayed gastric emptying was observed in 3 patients (3.8%). The learning curve analysis indicated a proficiency threshold after the 38th procedure, aligning with a subsequent decrease in operative times as the surgeon\u2019s experience progressed.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>RP\u2010RPPG is feasible and can be performed safely by an experienced surgeon without increasing early postoperative morbidity.<\/jats:p><\/jats:sec>","DOI":"10.1002\/wjs.12543","type":"journal-article","created":{"date-parts":[[2025,3,12]],"date-time":"2025-03-12T03:05:49Z","timestamp":1741748749000},"page":"1110-1114","source":"Crossref","is-referenced-by-count":3,"title":["Reduced\u2010Ports Robotic Pylorus\u2010Preserving Gastrectomy for Gastric Cancer"],"prefix":"10.1002","volume":"49","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-8248-9043","authenticated-orcid":false,"given":"So Hyun","family":"Kang","sequence":"first","affiliation":[{"name":"Department of Surgery Seoul National University Bundang Hospital  Seongnam Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Nehal","family":"Jambi","sequence":"additional","affiliation":[{"name":"Department of Surgery Seoul National University Bundang Hospital  Seongnam Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Eunju","family":"Lee","sequence":"additional","affiliation":[{"name":"Department of Surgery Chung\u2010Ang University Gwangmyeong Hospital  Gwangmyeong Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Young Suk","family":"Park","sequence":"additional","affiliation":[{"name":"Department of Surgery Seoul National University Bundang Hospital  Seongnam Korea"},{"name":"Department of Surgery Seoul National University College of Medicine  Seoul Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sang\u2010Hoon","family":"Ahn","sequence":"additional","affiliation":[{"name":"Department of Surgery Seoul National University Bundang Hospital  Seongnam Korea"},{"name":"Department of Surgery Seoul National University College of Medicine  Seoul Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yun\u2010Suhk","family":"Suh","sequence":"additional","affiliation":[{"name":"Department of Surgery Seoul National University Bundang Hospital  Seongnam Korea"},{"name":"Department of Surgery Seoul National University College of Medicine  Seoul Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hyung\u2010Ho","family":"Kim","sequence":"additional","affiliation":[{"name":"Department of Surgery Chung\u2010Ang University Gwangmyeong Hospital  Gwangmyeong Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2025,3,11]]},"reference":[{"key":"e_1_2_10_2_1","doi-asserted-by":"publisher","DOI":"10.1093\/bjs\/znab295"},{"key":"e_1_2_10_3_1","doi-asserted-by":"publisher","DOI":"10.1097\/sla.0000000000006503"},{"key":"e_1_2_10_4_1","doi-asserted-by":"publisher","DOI":"10.1007\/s00423\u2010022\u201002575\u20109"},{"key":"e_1_2_10_5_1","doi-asserted-by":"publisher","DOI":"10.1007\/s11605\u2010013\u20102419\u20107"},{"key":"e_1_2_10_6_1","doi-asserted-by":"publisher","DOI":"10.5230\/jgc.2022.22.e16"},{"key":"e_1_2_10_7_1","doi-asserted-by":"publisher","DOI":"10.5230\/jgc.2023.23.e33"},{"key":"e_1_2_10_8_1","doi-asserted-by":"publisher","DOI":"10.4240\/wjgs.v14.i10.1107"},{"key":"e_1_2_10_9_1","doi-asserted-by":"publisher","DOI":"10.3748\/wjg.v25.i36.5494"},{"key":"e_1_2_10_10_1","doi-asserted-by":"publisher","DOI":"10.1097\/sla.0b013e318294d142"},{"key":"e_1_2_10_11_1","doi-asserted-by":"publisher","DOI":"10.1097\/sla.0000000000003583"}],"container-title":["World Journal of Surgery"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/pdf\/10.1002\/wjs.12543","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,10,10]],"date-time":"2025-10-10T01:13:02Z","timestamp":1760058782000},"score":1,"resource":{"primary":{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/10.1002\/wjs.12543"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2025,3,11]]},"references-count":10,"journal-issue":{"issue":"4","published-print":{"date-parts":[[2025,4]]}},"alternative-id":["10.1002\/wjs.12543"],"URL":"https:\/\/doi.org\/10.1002\/wjs.12543","archive":["Portico"],"relation":{},"ISSN":["0364-2313","1432-2323"],"issn-type":[{"value":"0364-2313","type":"print"},{"value":"1432-2323","type":"electronic"}],"subject":[],"published":{"date-parts":[[2025,3,11]]}}}
