Patients were classified into hinotori (n = 78) and da Vinci Xi (n = 126) groups. Propensity score matching (PSM) and inverse probability of treatment weighting (IPTW) were used to adjust for patient and tumor characteristics.Results: After adjustment, the baseline demographics were well-balanced between the groups. No significant intergroup differences were observed in operative time, console time, blood loss, or postoperative hospital stay. Both groups had comparable histopathological outcomes. The incidence of Clavien-Dindo grade ≥ II complications did not differ significantly between the two groups after PSM or IPTW adjustments.Conclusions: This study showed that robotic colorectal surgery using the hinotori system is as safe and feasible as surgery performed using the da Vinci Xi system.","PeriodicalId":22163,"journal":{"name":"Surgery Today","volume":" ","pages":"2513-2523"},"PeriodicalIF":2.3,"publicationDate":"2026-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148391757","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Among the 133 patients who underwent pancreatectomy for PDAC, 33 (24.8%) developed STM, 23 (69.7%) of which progressed to local recurrence. No significant predictive factors for STM occurrence were identified in the PDAC patients. However, among the PDAC patients with STM, those who had received neoadjuvant radiotherapy were significantly less likely to develop local recurrence than those who had not (P = 0.0259).Conclusion: STMs occurred after pancreatectomy only in patients with PDAC, and neoadjuvant radiotherapy may influence whether the STM progresses to local recurrence, although the sample size was limited.

This study aimed to evaluate whether these advantages provide clinical benefits for elderly patients who are vulnerable to surgical stress.Methods: This retrospective study included 656 patients with gastric or esophagogastric junction cancer who underwent R0 RG or LG. The patients were stratified into elderly (≥ 75 years, n = 300) and non-elderly (< 75 years, n = 356). Propensity score matching was performed within each group to adjust baseline differences, and the outcomes were compared.Results: In elderly patients, RG caused fewer postoperative complications (grade ≥ III) (3.0% vs. 11.0%, P = 0.03) and lower postoperative C-reactive protein (P = 0.03) and drain amylase levels (P = 0.02). In non-elderly patients, RG led to lower drain amylase levels (P = 0.002). However, the complication rates did not differ significantly (3.8% vs. 7.6%, P = 0.29). No significant differences in the recurrence-free survival or overall survival were observed.Conclusions: RG may reduce postoperative complications in elderly patients, thus supporting a potential benefit in this population.","PeriodicalId":22163,"journal":{"name":"Surgery Today","volume":" ","pages":"2340-2351"},"PeriodicalIF":2.3,"publicationDate":"2026-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148259606","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
