After AI review, residents recorded an ordinal ImpactScore (0-3: no change to major change) describing the magnitude of plan modification and rated usefulness (1-5 Likert). Paired analyses compared pre- vs post-AI changes in plan structure and narrative length across domains; mixed-effects models evaluated associations with PGY level and subspecialty.ResultsAcross all 267 paired resident-case observations, AI altered operative plans in 91.0% (243/267; 95% CI, 87.2%-93.8%), with a mean ImpactScore of 1.32 ± 0.75 (median 1 [IQR 1-2]). Impact differed by PGY (H = 25.02; P = 1.53 × 10-5), with PGY2 and PGY3 showing lower ImpactScores than PGY1 in mixed-effects modeling. Subspecialty differences were observed (H = 11.95; P = 0.036), with higher impact in sleep surgery than laryngology. After AI review, operative step descriptions shortened (mean -192.2 characters; P < 10-40) and safety text shortened (-18.3 characters; P < 10-22), while complication text modestly increased (+8.1 characters; P = 0.0039). Mean usefulness was 2.90 ± 1.10 and increased with ImpactScore (β = 0.264; P = 0.003).ConclusionIn simulation-based operative planning, ChatGPT-5 frequently prompted residents to modify and reorganize operative plans, with effects varying by training level and case type. LLM assistance may function as a reflective structuring aid, but requires supervised use given occasional clinically concerning model suggestions.","PeriodicalId":22095,"journal":{"name":"Surgical Innovation","volume":" ","pages":"15533506261446833"},"PeriodicalIF":1.6,"publicationDate":"2026-04-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147781681","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}

Despite the increasing popularity of robot-assisted minimally invasive esophagectomy (RAMIE), its potential advantages over MIE are yet unknown.MethodsWe searched PubMed, Embase, and the Cochrane database for randomized controlled trials (RCTs) comparing RAMIE to MIE in patients with esophageal cancer that reported the outcomes of interest. Mean differences (MD) with 95% confidence intervals (CI) were collected. Statistical analysis was performed using Review Manager 5.4 (Cochrane Collaboration). Heterogeneity was assessed with I2 statistics.ResultsWe included three RCTs with 721 patients, of whom 364 (50,4%) underwent RAMIE. The number of dissected nodes increased in patients undergoing RAMIE (MD 3.72; 95% CI 1.07 to 6.37; P = 0.006).

Eighty geriatric patients (60 years old and older) were selected and compared (LC, n = 40; GSLC, n = 40). Stress biomarkers (norepinephrine, cortisol, and blood glucose) and inflammatory biomarkers (procalcitonin, C-reactive protein, and tumor necrosis factor-alpha) were evaluated before surgery and at 24 and 72 hours after surgery, as well as during the operative time, and related to estimated blood loss, postoperative complications, and length of stay. All in all, GSLC showed a steady reduction in postoperative increase in stress and inflammatory markers over time compared to LC, indicating a less intense physiologic perturbation during the initial phase of recovery. Results of the operation were more favorable to GSLC, with reduced operative time and less blood loss, and the postoperative endpoints showed fewer early complications and a shorter stay. These results indicate that gasless single-channel methods can be potentially helpful in physiologically vulnerable patients in the elderly, as they diminish the early postoperative stress and inflammatory processes; nevertheless, due to the retrospective study, standardized method of technique, and extended period of follow-up, prospective randomized trials are needed to confirm these relationships and to formulate clinical practice recommendations.","PeriodicalId":22095,"journal":{"name":"Surgical Innovation","volume":" ","pages":"15533506261434824"},"PeriodicalIF":1.6,"publicationDate":"2026-04-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147618773","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}

Safety was assessed based on postoperative and anastomotic complications, as well as endoscopic findings of colonic changes at the FDD fixation site. Effectiveness was evaluated by the rate of permanent stoma formation.ResultsAmong 91 patients, 8 (8.8%) required surgical re-intervention. Of these, five patients experienced anastomotic complications necessitating stoma formation: rectovaginal fistula (n = 2), delayed anastomotic leakage (n = 2), and rectourethral fistula (n = 1). One patient developed severe ileus requiring surgery, which also resulted in stoma formation. Overall, six patients (6.6%) underwent permanent stoma formation during a mean follow-up period of 24 months. Endoscopic follow-up identified colonic luminal deformities in 15 patients (16.5%), most of which were asymptomatic mucosal edema or erosion (n = 12).
