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.</p>","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}

As previous studies have primarily utilised VR systems without haptic feedback, there remains limited evidence on the impact of more immersive, tactilely responsive platforms. This study aimed to assess if haptic-enabled VR technology could accelerate the acquisition of hip arthroplasty skills.MethodsTwenty undergraduate medical students (12 Female, 8 Male; age = 20 ± 2 years) were randomly allocated to either a 60-minute haptic VR training session or a traditional mentor teaching session on hip arthroplasty. After training, all participants performed a SawBone simulated hemiarthroplasty procedure in a physical environment. Outcomes measured included implant depth error, which determined procedural success, operative time, and an objective evaluation of technical skills by a blinded Consultant Orthopaedic Surgeon.ResultsWe observed no difference in levels of implant depth error (<i>P</i> = .705), rated technical skill (<i>P</i> = .704), or operative time (for successful implant insertions; <i>P</i> = .551) between traditional and VR-trained groups.ConclusionsThese results indicate that VR may, at least, serve as a valuable adjunct to traditional early-stage training in complex open procedures like joint arthroplasty.

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.

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.

All participants performed a supervised diagnostic arthroscopy. Performance parameters (completion time, lookdowns, instrument loss, triangulation time, interventions) and Arthroscopic Surgery Skill Evaluation Tool (ASSET) scores were analyzed.

The objective of this study was to determine if ultrasound (US) is a feasible alternative to MRI in preoperative PSD mapping.MethodsA prospective, proof of concept study was conducted on patients treated with laser ablation in 2 Belgian hospitals between Jan 2023 and Dec 2024. The patients underwent a preoperative US and MRI. Sinus characteristics were described according to a predefined protocol. The agreement between US and MRI was quantified using the intraclass correlation coefficient (ICC) for the measurement of 3 sinus dimensions (length, depth and width) and Cohen's kappa coefficient (k) for the detection of side branches.Results30 patients were included with a median age of 27 years (IQR 20-35).
