Patients using mobile apps had a lower risk of serious complications, emergency room visits and readmissions after surgery, but the benefits depended on physician or other clinician involvement, rather than the technology alone, according to research presented at the Anesthesiology 2026 annual meeting. https://medicalxpress.com/news/2026-10-mobile-app-complications-surgery.html Sat, 17 Oct 2026 07:00:02 EDT news711287043 A research team from the Faculty of Dentistry at The University of Hong Kong (HKU), working in collaboration with Su Ryon Shin's group at Brigham and Women's Hospital, Harvard Medical School, has advanced and preclinically validated a shape-adaptive hydrogel designed for challenging clinical trauma scenarios involving severe bleeding, irregular bone defects and comminuted fractures. https://medicalxpress.com/news/2026-10-moldable-gel-bone-preclinical.html Thu, 15 Oct 2026 19:20:01 EDT news711296221 When replacing the aortic valve, a small aortic root can limit the size of the prosthetic valve that can be implanted. If the new valve is too small in relation to the patient's body, the heart must continue to work against increased resistance—a so-called patient-prosthesis mismatch, which is associated with poorer clinical outcomes. https://medicalxpress.com/news/2026-10-aortic-root-enlargement-technique-surgeons.html Thu, 15 Oct 2026 12:00:08 EDT news711283849 A donor heart recovery technique developed at Vanderbilt Health has been successfully adapted for children by pediatric heart transplant surgeons at Monroe Carell Jr. Children's Hospital at Vanderbilt, potentially expanding access to lifesaving heart transplants for children. https://medicalxpress.com/news/2026-10-heart-recovery-technique-pediatric-transplants.html Wed, 07 Oct 2026 17:00:01 EDT news710602501 Surgery to remove lymph nodes in the neck may interfere with cerebrospinal fluid (CSF) drainage from the brain, contributing to cognitive impairment, according to new multicenter research led by Weill Cornell Medicine scientists. https://medicalxpress.com/news/2026-09-neck-lymph-node-linked-cognitive.html Tue, 29 Sep 2026 11:00:17 EDT news709888708 A new AI-based model can predict where glioblastoma is most likely to return after initial surgery, potentially giving doctors a chance to treat it before it becomes visible on MRI. https://medicalxpress.com/news/2026-09-ai-tool-glioblastoma-surgery.html Mon, 28 Sep 2026 10:20:14 EDT news709808402 Underweight patients are more likely to die after emergency general surgery than patients who are normal weight or overweight, and patients who are both frail and underweight face an even higher risk of death and other adverse clinical outcomes, according to new research findings. https://medicalxpress.com/news/2026-09-underweight-patients-higher-odds-death.html Fri, 25 Sep 2026 11:00:28 EDT news709546382 A new global study into appendicitis has found major inequalities in care, with some countries having little access to CT imaging or minimally invasive surgery—resulting in poorer patient outcomes. https://medicalxpress.com/news/2026-09-appendicitis-patients-hours-rupture-global.html Wed, 23 Sep 2026 18:30:05 EDT news709359129 Personalized nutrition may play a vital role in helping critically ill patients recover more quickly and with fewer complications after major surgery, trauma, burns and other life-threatening conditions. https://medicalxpress.com/news/2026-09-tailored-nutrition-critically-ill-patients.html Mon, 21 Sep 2026 09:20:01 EDT news709199339 Minimally invasive surgery is a promising approach that allows doctors to intervene inside the body through small incisions, typically using advanced instruments. These can include small robotic instruments controlled by a surgeon, cameras or devices that measure specific signals. https://medicalxpress.com/news/2026-09-tiny-tactile-sensor-distinguish-tissues.html Fri, 18 Sep 2026 09:20:06 EDT news708683719 Researchers have created a new technique that accurately and rapidly matches X-rays captured during surgery with a patient's preoperative 3D medical scan. This method could make it easier for clinicians to precisely guide minimally invasive surgical tools, leading to faster and safer procedures. https://medicalxpress.com/news/2026-09-patient-specific-ai-technique-minimally.html Wed, 16 Sep 2026 15:20:04 EDT news708788281 During transplantation, blood flow to the donor liver must stop as it's moved to the recipient. Once transplanted, oxygen-rich blood is restored, yet doing so can cause what is called ischemia-reperfusion injury. To protect transplanted livers from this tissue damage, researchers at The Hospital for Sick Children (SickKids) have discovered a way to protect dying cells from rupturing and affecting the surrounding area. https://medicalxpress.com/news/2026-09-dying-cells-rupturing-donor-livers.html Tue, 15 Sep 2026 13:00:03 EDT news708692102 More than three-quarters of donated lungs offered for transplantation are not used, according to the UK's National Institute for Health and Care Excellence, contributing to a chronic shortage of organs for patients with end-stage lung disease. https://medicalxpress.com/news/2026-09-metabolic-tech-donor-lungs-transplantation.html Thu, 10 Sep 2026 10:40:06 EDT news708253105 A study titled "Liposuction versus conservative therapy for patients with lipoedema: A randomized controlled multi-center clinical trial" published in The Lancet, provides the first large-scale, multicenter evidence base for the surgical treatment of lipedema. https://medicalxpress.com/news/2026-09-liposuction-lipedema-pain-treatment.html Fri, 04 Sep 2026 12:00:03 EDT news707740382 Researchers at NYU Abu Dhabi have developed BRIDGE (Biodegradable aRchitected Internal DrainaGE), a biodegradable, 3D-printed gastric stent that could improve treatment for gastric leaks, a serious complication following weight-loss surgery. By combining an advanced internal lattice design with biodegradable materials, the new device more than doubles drainage performance while potentially eliminating the need for a second procedure to remove the stent after healing. https://medicalxpress.com/news/2026-08-biodegradable-3d-gastric-stent-lattice.html Tue, 25 Aug 2026 11:00:01 EDT news706859767 A new treatment for earlier-stage rectal cancer could transform how patients are treated for the disease, according to a landmark clinical trial. https://medicalxpress.com/news/2026-08-clinical-trial-rectal-cancer-major.html Mon, 24 Aug 2026 14:40:08 EDT news706800141
