https://medicalxpress.com/surgery-news/ en-us Latest medical news and research in General surgery UPMC and University of Pittsburgh clinician-scientists have weaned and kept multiple liver transplantation patients off of all immunosuppressant drugs for more than three years through a first-in-human clinical trial of a unique "immune priming" therapy. https://medicalxpress.com/news/2026-04-human-trial-primes-immune-donor.html Fri, 17 Apr 2026 05:00:05 EDT news695548141 Researchers have developed a compact camera that captures ultraviolet, near-infrared, and visible images using a single chip. Inspired by the multiwavelength vision capability of the mantis shrimp, the camera could help surgeons identify lymph nodes connected to a tumor and assess whether cancer has spread to them, making cancer surgery safer and less invasive. https://medicalxpress.com/news/2026-04-shrimp-camera-hidden-cancer-surgeons.html Thu, 16 Apr 2026 10:00:04 EDT news695547541 Biomedical researchers have designed an injectable microgel to help reduce bleeding in infants who require surgical care. In an animal model, the engineered microgel reduced bleeding by at least 50%. The paper, "Hemostatic B-Knob Triggered MicroGels (BK-TriGs) to Address Bleeding in Neonates," is published in the journal Science Advances. https://medicalxpress.com/news/2026-04-particle-surgery-safer-infants.html Fri, 03 Apr 2026 14:00:02 EDT news694280882 It is safe for patients to receive a donor liver that has been intentionally preserved overnight using machine perfusion to enable a daytime transplant. This is shown by a study performed at the University Medical Center Groningen (UMCG) in the Netherlands, including transplants using all types of donor organs. The post-transplant outcomes are at least as good as those for livers that were not treated with machine perfusion, or were treated for only a short time, prior to transplantation. https://medicalxpress.com/news/2026-04-overnight-machine-perfusion-liver-transplants.html Fri, 03 Apr 2026 11:00:04 EDT news694350601 Researchers at the Icahn School of Medicine at Mount Sinai and the Mount Sinai Tisch Cancer Center have found that adults aged 80 and older with early-stage lung cancer can safely undergo surgery and achieve outcomes comparable to younger patients, challenging longstanding assumptions about age and cancer treatment. https://medicalxpress.com/news/2026-04-lung-cancer-surgery-safe-patients.html Thu, 02 Apr 2026 13:20:03 EDT news694353661 Deep cuts from accidents or surgeries require stitches, typically followed by oral anti-inflammatory medications like ibuprofen. While these medications help with pain, they don't act specifically on the wounds. Consequently, the site of the stitches can get inflamed, which could slow healing and lead to scarring. https://medicalxpress.com/news/2026-03-surgical-anti-inflammatory-drugs-wound.html Tue, 24 Mar 2026 05:00:02 EDT news693473461 Recent research provides robust evidence for the use of a digital visualization and decision support tool in colorectal (bowel) surgery. This is the first time that a digital decision support tool has been conclusively proven to significantly improve outcomes in this type of surgery. The study is published in The Lancet Gastroenterology & Hepatology. https://medicalxpress.com/news/2026-03-digital-decision-tool-proven-bowel.html Fri, 20 Mar 2026 19:30:01 EDT news693219001 Scientists from Great Ormond Street Hospital (GOSH) and University College London (UCL) have created the first lab‑grown esophagus—the food pipe—shown to safely replace a full section of the organ and restore normal function, including swallowing, in a growing animal without the need for immunosuppression. https://medicalxpress.com/news/2026-03-tissue-children-born-esophagus.html Fri, 20 Mar 2026 06:00:01 EDT news693131341 A widely used fracture risk calculator may help guide surgical decisions to treat patients with an endocrine disorder called primary hyperparathyroidism (PHPT) that causes progressive bone loss, according to a study led by UT Southwestern Medical Center researchers. The findings, published in JAMA Network Open, suggest the Fracture Risk Assessment Tool (FRAX) could be used to identify patients who may benefit from a parathyroidectomy to potentially prevent fractures. https://medicalxpress.com/news/2026-03-fracture-patients-benefit-parathyroid-surgery.html Thu, 19 Mar 2026 16:00:03 EDT news693150781 An international research team led by the Levenberg Laboratory in the Faculty of Biomedical Engineering at the Technion-Israel Institute of Technology has succeeded in developing a first-of-its-kind, three-dimensional implant that combines muscle and fat tissues, a lymphatic network, and a hierarchical blood vessel network. The researchers' findings are published in Cell Biomaterials. https://medicalxpress.com/news/2026-03-implant-treatment-significant-tissue-loss.html Tue, 17 Mar 2026 17:30:01 EDT news692985244 Researchers have unlocked the possibility of creating smart wound dressings that enable real-time monitoring while also being able to deliver healing agents in one simple, scalable platform. https://medicalxpress.com/news/2026-03-smart-bandage-wounds.html Tue, 17 Mar 2026 07:10:01 EDT news692949181 Biomaterials are specifically engineered to support tissue, nerve and muscle regeneration across the body, yet physicians and researchers have limited control over the size and connectivity of the internal pores that transfer oxygen and vital nutrients to where they are most needed. To solve this problem and better support tissue regeneration, a team at Penn State has designed a new class of tunable biomaterials. https://medicalxpress.com/news/2026-03-qa-gassing-bioengineered-materials-wound.html Sat, 14 Mar 2026 14:00:04 EDT news692373640 Resection of tumors in the caudate lobe (a deep, hard-to-reach part of the liver) is recognized as one of the most technically challenging procedures in hepatic surgery due to its unique anatomical position and complex vascular relationships. Researchers at Boston University Chobanian & Avedisian School of Medicine now show that it is possible to remove the caudate lobe safely using a surgical robot, even in an older patient, and still remove the cancer completely. https://medicalxpress.com/news/2026-03-robotic-surgery-hard-caudate-lobe.html Fri, 06 Mar 2026 14:40:02 EST news692024265 A new international study published in eClinicalMedicine has mapped global blood transfusion practices for life-threatening abdominal injuries, highlighting significant variation in care worldwide and opportunities for health systems to learn from one another. The work represents the first multicenter international study to report on blood transfusion strategies for patients undergoing emergency abdominal surgery following trauma (trauma laparotomy). https://medicalxpress.com/news/2026-03-international-trauma-analysis-big-transfusion.html Wed, 04 Mar 2026 18:30:03 EST news691835882 Mayo Clinic researchers have identified a hidden "movement map" deep within the brain—a discovery that could help surgeons reduce side effects from epilepsy procedures and guide future treatments for speech and movement disorders. In a study published in the Proceedings of the National Academy of Sciences, the team reports that a small, buried brain region called the insula contains its own organized map of the body. Distinct areas within the insula are linked to movement of the hands, feet, and tongue. https://medicalxpress.com/news/2026-03-hidden-brain-epilepsy.html Wed, 04 Mar 2026 15:40:01 EST news691856687 Lasers cut precisely and without contact—ideal for surgery. The problem is that in hard tissues such as bone, they are too slow and do not cut deep enough. Researchers at the University of Basel have now demonstrated a way to cut much deeper and faster with a surgical laser than with previous laser systems. https://medicalxpress.com/news/2026-02-laser-surgery-bone-deeper.html Sun, 01 Mar 2026 11:00:05 EST news691381480 Cold plasma devices are increasingly used across surgical procedures, including skin rejuvenation, scar remodeling, liposuction and diabetic wounds. A recent study from Thomas Jefferson University found that using an FDA-approved cold plasma device can enhance tissue healing after surgery by activating a wound-healing response. https://medicalxpress.com/news/2026-02-cold-plasma-surgery-recovery-faster.html Sat, 28 Feb 2026 07:00:01 EST news691482499
