Warm humidified carbon dioxide insufflation (WHCI), delivered intraoperatively at 37°C and near-100% humidity, has emerged as a promising adjunct to preserve peritoneal physiology in open surgery. By maintaining normothermia, reducing tissue desiccation, attenuating systemic inflammation, and supporting tissue oxygenation, WHCI may directly address several mechanisms implicated in the pathogenesis of POI.PurposeTo outline the physiological rationale for WHCI in open abdominal surgery and introduce a multicentre randomised controlled trial designed to determine whether WHCI accelerates return of bowel function following open colorectal surgery.Research DesignPerspective article incorporating a narrative review of existing evidence and the protocol overview of a forthcoming multicentre, single-blinded randomised controlled trial.Study SampleThe proposed trial will enrol 264 adults (132 per arm) undergoing elective or emergency open colorectal surgery across three Monash Health hospitals (Dandenong, Monash Medical Centre, and Casey), with randomisation stratified by urgency.Data Collection and AnalysisThe primary outcome will be the proportion of patients regaining bowel function (passage of flatus or stool) within 72 hours postoperatively, assessed at 24-hour intervals. Secondary outcomes include length of stay, readmission, return to theatre, postoperative nausea and vomiting, and use of oral Gastrografin follow-through. Sample size calculations anticipate a reduction in POI from 30-35% to 15%, with α = 0.05 and 80% power, allowing for 10% attrition.ResultsExisting evidence from open colorectal, cardiac, and orthopaedic surgery demonstrates reductions in peritoneal mesothelial injury, lower postoperative C-reactive protein, improved wound and core temperature, and reduced intra-wound particulate contamination. However, no adequately powered trial has yet evaluated whether these physiological benefits translate into faster return of bowel function.ConclusionsWHCI is a physiologically grounded, low-risk, and low-cost intraoperative adjunct that may directly address several mechanisms implicated in the pathogenesis of POI. If validated by the proposed trial, WHCI could redefine perioperative best practice and extend the thermoregulatory standards of laparoscopy into open surgery.</p>","PeriodicalId":22095,"journal":{"name":"Surgical Innovation","volume":" ","pages":"15533506261451394"},"PeriodicalIF":1.6,"publicationDate":"2026-05-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147989040","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}

Conventional straight arthroscopic burs (SABs) offer limited mobility due to geometric and soft tissue restrictions, often necessitating portal adjustments or tissue releases. Articulating rotary burs (ARB) incorporate adjustable articulation angles to enhance mobility and minimize collateral damage. This study aimed to quantitatively evaluate the cutting surface area (CSA) of a SAB and an ARB to compare efficiency in bone resection.MethodsA 3D point cloud analysis was performed in SolidWorks (Dassault Systèmes, Vélizy-Villacoublay, France) to compare CSA of a 5.0 mm SAB and a 5.0 mm ARB (Articulator™ Arthroscopic Bur, Joint Preservation Innovations, Naperville, IL), both with ball bur heads. Analyses accounted for continuous rotation about the tool's long axis. The SAB was compared with the ARB at 0°, 15°, and 30° distal articulation. Surface areas are reported in in² with metric equivalents (mm²). An aggregate motion-envelope CSA (0°-30°) was calculated as the sum of articulated positions.ResultsThe CSA of the SAB was 0.081 in² (52.3 mm²). The ARB CSA was 0.081 in² (52.3 mm²) at 0°, 0.203 in² (131.0 mm²) at 15°, and 0.284 in² (183.2 mm²) at 30°, totaling 0.568 in² (366.5 mm²).

While triangulation and traction-countertraction are widely recognized as geometric principles for exposure and transection, the geometric conditions that enable the dynamic advancement of dissection along tissue interfaces have not been clearly articulated.MethodsWe performed a schematic geometric analysis of surgical dissection focusing on the relationships among traction direction, opposing tissue surfaces, and the dissecting edge. Based on this analysis, we introduce Cornering as a conceptual framework describing how dissection advances along the intersection of 2 tissue planes through the active formation and maintenance of a dissectable edge under tension. We further define <i>planarization</i> as the local geometric state in which tissue becomes suitable for controlled division, and <i>decornering</i> as the terminal transition where opposing planes resolve into a continuous surface.ResultsCornering highlights that effective dissection depends on maintaining an appropriate three-dimensional dihedral angle between opposing surfaces, allowing the dissecting edge to remain in a planarized state. Within this framework, inefficient or unsafe dissection is interpreted as insufficient traction, inappropriate angulation, or loss of effective depth. Two modes of Cornering are identified: surface-based Cornering between tissue planes and axis-based Cornering along cylindrical structures.ConclusionsCornering provides a geometric framework that formalizes surgical dissection as a reproducible process. By extending established principles such as triangulation and traction-countertraction, it offers a practical and visually interpretable model that may support surgical education, intraoperative assessment, and technique standardization in MIS.</p>","PeriodicalId":22095,"journal":{"name":"Surgical Innovation","volume":" ","pages":"15533506261451920"},"PeriodicalIF":1.6,"publicationDate":"2026-05-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147875789","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}

Patient CT or MRI data were imported to determine key dimensions. Draft 3D models were provided to sales representatives, who relayed them to manufacturers' engineers for assessment of manufacturability and refinement into production drawings.

This manuscript introduces a novel modular abdominal simulation environment (MASE) with the ability to insufflate under standard parameters to accommodate laparoscopic and robotic surgery training and assessment.Methodology and Device DescriptionCT scans of a deidentified patient pelvis and spine are processed, reconstructed, and modified into 3D printable files, then printed using a high-fidelity resin printer. Silicone skin is developed to cover the MASE and mechanically fixed to create an air-tight seal. Insufflation capability is tested by measuring the pre- and post-insufflation height of the model, as well as internal pressure.Preliminary ResultsMASE meets the following criteria: anatomical accuracy, scale-to-life, and re-usability. Its ability to be insufflated via a Veress needle at Palmer's point recreates a pneumoperitoneum (increasing in height by 108%), allowing for effective port placement and clear visualization with a laparoscope. The platform successfully supports fundamentals of laparoscopic surgery (FLS) tasks including intracorporeal knot tying and peg transfer both with laparoscopic tools and robotic system.Current StatusCurrent work includes a more efficient locking mechanism, incorporation of the retroperitoneal space, and addition of synthetic/explant organs for high-fidelity abdominal simulation.
