Surgery represents one of the most dynamic frontiers in modern medicine, where precision, innovation, and human care converge to treat conditions that often defy other therapies. This field encompasses everything from minimally invasive procedures and robotic assistance to complex organ transplants and trauma care, constantly evolving as new technologies emerge to improve patient outcomes and recovery times.

On Gist.Science, we track every new preprint in this category as it appears on medRxiv, ensuring you stay ahead of the curve before formal publication. We process each submission to provide both plain-language explanations for broader understanding and detailed technical summaries for researchers, bridging the gap between raw data and actionable insight. Below are the latest papers in surgery, curated and summarized for clarity and depth.

Cognitive Outcomes After Stenting and Endarterectomy: A Systematic-Review and Meta-Analysis

This systematic review and meta-analysis of 68 studies indicates that carotid revascularization (both endarterectomy and stenting) is associated with cognitive improvement, particularly on MoCA tests at long-term follow-up, while finding no significant difference in cognitive outcomes between the two procedures despite limited comparative evidence.

Chyme reinfusion using the Insides System to reduce parenteral nutrition dependence in Type 2 intestinal failure: multicentre randomised controlled trial (REINFUSE)

This multicentre randomised controlled trial demonstrates that device-assisted chyme reinfusion using the Insides System significantly reduces parenteral nutrition dependence and achieves complete cessation in a substantial proportion of patients with Type 2 intestinal failure due to double enterostomy or enterocutaneous fistula, while maintaining an acceptable safety profile.

Thoracostomy Tube Infections: Prevalence and Associated Clinical Characteristics at a Tertiary Hospital in Northern Tanzania

A prospective cohort study at KCMC Zonal Referral Hospital in Northern Tanzania revealed a 26.2% prevalence of thoracostomy tube infections, primarily caused by *Pseudomonas aeruginosa* and *Staphylococcus aureus*, with prolonged tube duration and non-surgical ward admission identified as key risk factors.

Variation in Haemostasis and VTE Prophylaxis in Elective Adult Cranial Neurosurgery: A Global Survey of Perioperative Practice

This global survey of 456 neurosurgeons reveals substantial worldwide variation in perioperative haemostasis and venous thromboembolism prophylaxis practices for elective adult cranial surgery, driven by a mix of geographical socioeconomic factors and true clinical equipoise, thereby establishing an empirical foundation for future guideline development and trial design.

A Tale of Two Countries: Comparison of Rectal Cancer Characteristics Between Pakistani Americans and Native Pakistanis

This retrospective study reveals that native Pakistanis with rectal cancer are diagnosed at a significantly younger age and present with more aggressive tumor characteristics compared to Pakistani Americans, whose clinical profile appears intermediate between native Pakistanis and non-Hispanic Whites.

AENEAS Project: First real-time intraoperative application of machine vision-based anatomical guidance in neurosurgery

The AENEAS project demonstrates the first successful intraoperative deployment of a real-time, machine vision-based anatomical guidance system in neurosurgery, achieving reliable landmark detection with low latency to enhance surgical orientation and training.

Associations between Exposure to Perfluoroalkyl Substances with Subsequent Body Composition and Glycemic Responses to Bariatric Surgery

This prospective pilot study suggests that while higher baseline levels of specific perfluoroalkyl substances (PFNA and PFOS) are associated with reduced lean mass in bariatric surgery candidates, only PFNA burden appears to modestly correlate with attenuated postoperative metabolic and body composition recovery, though larger studies are needed to confirm these findings.

Peak Alpha Frequency as a Neural Marker of Postoperative Pain Outcomes in Spinal Fusion Surgery

This study demonstrates that faster preoperative peak alpha frequency (PAF) serves as a stable, trait-like neural marker capable of predicting meaningful long-term pain reduction and identifying treatment responders three months after spinal fusion surgery, suggesting its potential utility for preoperative risk profiling and personalized pain management.

Impact of Left Common Carotid Cannula Design on Flow Distribution and Cerebral Perfusion Pressure During Bilateral Selective Antegrade Cerebral Perfusion: An Experimental and Computational Study

This experimental and computational study demonstrates that variations in left common carotid cannula design significantly alter cerebral perfusion pressure and flow distribution during bilateral selective antegrade cerebral perfusion, posing potential risks for patients with limited collateral circulation.
