Roux-en-Y Gastric Bypass (RYGB) patients were more likely to have a 30-d readmission than SG (OR = 1.75 95% CI 1.03-2.96).

While robotic-assisted right hemi-hepatectomy (RRH) was associated with less blood loss and a lower intraoperative blood transfusion rate, but a longer operation time compared with open right hemi-hepatectomy.</div></div><div><h3>Conclusions</h3><div>RH is a safe and effective technique. In addition to less blood loss, robotic-assisted left hemi-hepatectomy had advantages in postoperative complications and postoperative stay, while RRH had advantages in intraoperative blood transfusions. However, operation time was longer for RRH than for open right hemi-hepatectomy.</div></div>","PeriodicalId":17030,"journal":{"name":"Journal of Surgical Research","volume":"303 ","pages":"Pages 261-267"},"PeriodicalIF":1.8,"publicationDate":"2024-10-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142400576","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
