We introduced robotic ultrasonic shears (longitudinal clustered shears [LCS]); however, the lack of an articulating joint limits operative angles. To overcome this, we implemented strategic surgical maneuvers. This study aimed to evaluate the liver transection efficiency of the robotic ultrasonic shears in RLR.MethodsFifty-three patients who underwent RLR concurrently between 2023 and 2025 were retrospectively analyzed (LCS group, n = 23; conventional [CONV] group using Maryland bipolar forceps, n = 30). We compared liver transection speed, total ischemia time, and short-term outcomes.ResultsDespite a lower proportion of low-difficulty cases in the LCS group, it demonstrated significantly higher transection speed (median: 0.71 vs 0.38 cm²/min, <i>P</i> < .001) and shorter total ischemia time (63 vs 78 min, <i>P</i> = .011). Postoperative albumin levels on days 3 and 5 were significantly higher (<i>P</i> = .004), and the complication rate (Clavien-Dindo grade ≥ II) was significantly lower (8.7% vs 30.0%, <i>P</i> = .049) in the LCS group. Multivariate analysis identified the use of LCS (<i>P</i> = .003) as an independent predictor of higher transection speed. Exploratory subgroup analyses confirmed that the LCS group had significantly higher transection speed in non-anatomical resections (<i>P</i> < .001) and significantly shorter ischemia time in anatomical resections (<i>P</i> = .021), although the higher transection speed in anatomical resections did not reach statistical significance.ConclusionsRobotic ultrasonic shears with optimized maneuvers significantly improve transection speed and reduce ischemia time, enhancing the efficiency of RLR.</p>","PeriodicalId":22095,"journal":{"name":"Surgical Innovation","volume":" ","pages":"15533506261477024"},"PeriodicalIF":2.2,"publicationDate":"2026-08-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148713634","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}

This study aimed to identify preoperative, intraoperative, and novel predictors of CVS quality using intraoperative doublet photography.MethodsThis prospective, single-centre observational study (March 2024-January 2025) evaluated CVS achievement in patients undergoing elective LC. Experienced surgeons assessed anterior and posterior view photographs.

Traditional risk scores, such as the Society of Thoracic Surgery (STS) and EuroSCORE II, have limitations in predicting outcomes, particularly in high-risk patients. Machine learning (ML) models may address these issues by detecting nuanced data patterns not captured by conventional methods. This systematic review and meta-analysis compared the efficacy of ML models with traditional risk scores in predicting outcomes after CABG.MethodsA comprehensive literature search of records up to August 14^th 2025, was conducted using PubMed, Embase, Web of Science, and the Cochrane Library. Studies included used ML algorithms and traditional risk scores to predict all-cause mortality (in-hospital, 30-day, or longer term as reported by each study) following CABG. Data extraction and quality assessment were independently performed by two reviewers. Meta-analyses were conducted using a linear mixed-effects model, with C-statistics as the primary measure of discrimination.ResultsTwenty-six studies, comprising 565 063 participants, met the inclusion criteria. The pooled C-statistic for ML models was 0.82 (95% CI 0.79-0.85), significantly higher than the 0.73 (95% CI 0.71-0.76) for traditional risk scores (<i>P</i> < 0.0001). The top-performing ML model achieved a C-statistic of 0.98 (CI 0.95-1.00). Calibration was reported inconsistently across studies and was synthesised narratively rather than quantitatively. Where reported, ML calibration was generally adequate but a robust head-to-head comparison with traditional risk scores was not possible. Subgroup analyses revealed consistent superior performance of ML models across various algorithms and covariate sets.ConclusionsIn this meta-analysis of predominantly internally-validated models, ML approaches showed higher pooled discrimination than traditional risk scores for mortality after CABG. However, given the small number of pooled studies, very high between-study heterogeneity (I² = 98%), the predominance of high risk-of-bias studies, and the scarcity of external validation, these findings should be interpreted as supporting the promise of ML rather than establishing proof of clinical superiority. Confirmatory prospective, externally validated studies are required before ML can be recommended for routine pre-operative risk stratification.</p>","PeriodicalId":22095,"journal":{"name":"Surgical Innovation","volume":" ","pages":"15533506261468192"},"PeriodicalIF":2.2,"publicationDate":"2026-08-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148680037","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}
