Many of those livers, particularly from older or medically complex donors, require careful evaluation before transplantation, and current assessments often sample only a small region of the organ. https://medicalxpress.com/news/2026-07-portable-ps-oct-scanner-reveal.html Wed, 08 Jul 2026 18:00:07 EDT news702741466 A landmark Northwestern Medicine study published in JAMA suggests lung transplantation can significantly extend survival in select patients with advanced lung cancer. https://medicalxpress.com/news/2026-07-lung-transplant-survival-patients-terminal.html Wed, 08 Jul 2026 15:20:03 EDT news702737704 For the first time, two teleoperated humanoid robots have been used to complete two surgeries during a preclinical trial, researchers report in the July 8 issue of the journal Nature. The work is the result of a collaboration between a team of engineers and a team of surgeons at the University of California San Diego. https://medicalxpress.com/news/2026-07-surgeons-teleoperated-humanoid-robots-surgery.html Wed, 08 Jul 2026 14:40:04 EDT news702729363 Researchers from UC Davis Medical Center have identified significant socioeconomic disparities among patients seeking treatment for complications after aesthetic surgery, according to a new study published in JPRAS Open. https://medicalxpress.com/news/2026-07-highlights-health-equity-financial-burden.html Tue, 07 Jul 2026 21:40:01 EDT news702660301 Ann & Robert H. Lurie Children's Hospital of Chicago achieved more than a 13-fold improvement in surgical safety after implementing a series of interventions based on high-reliability principles across its operating rooms. The hospital went from experiencing a serious safety event about every 2,977 surgical cases to a stretch of 39,654 cases over 585 days without a single serious safety event, according to the study published in Pediatrics. https://medicalxpress.com/news/2026-07-safety-surgery-children.html Thu, 02 Jul 2026 07:20:01 EDT news702188462 Whether children receive an opioid prescription after surgery varies substantially by procedure type and hospital, according to a new national analysis published in the Journal of the American College of Surgeons. The study also found that overall, nearly one-third of children are prescribed opioids after surgery. https://medicalxpress.com/news/2026-07-children-opioids-surgery-varies-hospital.html Wed, 01 Jul 2026 15:40:01 EDT news702135541 Both Roux-en-Y gastric bypass (RYGB) and sleeve gastrectomy are cost-effective compared with no surgery for adolescents with severe obesity, according to a study published online June 15 in JAMA Network Open. https://medicalxpress.com/news/2026-06-roux-en-gastric-bypass-sleeve.html Tue, 30 Jun 2026 18:20:01 EDT news702053791 What do laparoscopic surgery and robotic lunar construction have in common? Plenty, as it turns out, for Shuai Li, Ph.D., associate professor in the University of Florida's Department of Civil & Coastal Engineering. https://medicalxpress.com/news/2026-06-robotic-surgical-cameras-mimic-human.html Tue, 30 Jun 2026 09:00:01 EDT news702021122 The liver is one of the few organs capable of regenerating after surgery—a remarkable ability that makes lifesaving procedures possible for thousands of patients each year. But not every liver regenerates as expected. Some patients develop post-hepatectomy liver failure, a serious complication that remains a leading cause of death after liver surgery. Now, a discovery by a Michigan State University researcher is challenging a long-held belief about how the liver repairs itself after surgery. https://medicalxpress.com/news/2026-06-plasminogen-spur-stronger-liver-surgery.html Thu, 25 Jun 2026 17:20:07 EDT news701619901 Taking a supplement before a hepatectomy, a surgery in which part of the liver is removed, may help the organ recover more quickly and become more resistant to further damage. This is the main finding of a study conducted by researchers at the State University of Campinas (UNICAMP) in the state of São Paulo, Brazil. The researchers investigated the effects of beta-hydroxy-beta-methylbutyrate (HMB) in an experimental model using mice. The results indicate that preoperative use of the supplement preserves the energy function of liver cells and improves the quality of regeneration following major injury. These results were published in March in the journal Acta Physiologica. https://medicalxpress.com/news/2026-06-supplement-surgery-liver-regeneration.html Thu, 25 Jun 2026 11:26:38 EDT news701605548 Researchers at the University of Massachusetts Amherst have analyzed nearly 86,500 surgeries at Baystate Medical Center to identify the top factors that influence inefficiencies in surgeon schedules. Having an efficiently organized surgical schedule has the potential to lower costs and reduce surgeon burnout, which would also improve patient outcomes. https://medicalxpress.com/news/2026-06-surgeons-factors-hospital-efficiency.html Wed, 24 Jun 2026 13:40:05 EDT news701525401 The Ross Procedure, a highly specialized option for aortic valve replacement, is associated with significant long-term durability and excellent outcomes in a wide range of adult patients with aortic valve disease. These are the results of a new study led by Mount Sinai heart surgeon Ismail El-Hamamsy, MD, Ph.D., the director of aortic surgery for Mount Sinai Health System, and published in the Journal of the American College of Cardiology (JACC). https://medicalxpress.com/news/2026-06-procedure-excellent-outcomes-durability-efficacy.html Tue, 23 Jun 2026 10:00:03 EDT news701335981 A liver cancer diagnosis frequently leads to surgery, with the goal of completely removing all malignant tissue. To ensure that no tumor remains in the organ, the resected tissue is subjected to frozen-section analysis during the procedure. This analysis takes time: Patients remain under general anesthesia throughout, operating room staff are occupied, and with every passing minute the risk of complications increases. https://medicalxpress.com/news/2026-06-ai-based-tissue-anomaly-duration.html Mon, 22 Jun 2026 15:20:03 EDT news701358601 Global health policymakers should focus on the way entire health care systems work together, argue researchers in new findings. Improving one element does not always create better outcomes if the wider system is not ready. https://medicalxpress.com/news/2026-06-patients-injury-intentioned-backfire.html Sun, 21 Jun 2026 18:30:01 EDT news701013787 A study led by researchers at Children's Hospital of Philadelphia (CHOP) demonstrates a new method of using decellularized cartilage with patient-specific cells to help enlarge pediatric airways narrowed as a result of severe subglottic stenosis. Researchers demonstrate that this new method is faster, more effective and able to overcome issues associated with the current standard grafts, such as donor site morbidity, insufficient tissue volume and a delayed timeline. The findings are published in the journal Nature Communications. https://medicalxpress.com/news/2026-06-scientists-personalized-cartilage-graft-infants.html Wed, 17 Jun 2026 05:00:05 EDT news700744261 Metabolic and bariatric surgery for teens with severe obesity was found to be cost-effective over 10 years, according to a new analysis from Ann & Robert H. Lurie Children's Hospital of Chicago published in JAMA Network Open. While long-term clinical benefits of weight-loss surgery for eligible teens have been well established, and it is recommended by the American Academy of Pediatrics, insurance coverage has been limited and few teens can take advantage of the surgery. https://medicalxpress.com/news/2026-06-economic-case-teen-weight-loss.html Mon, 15 Jun 2026 11:00:14 EDT news700730821 Skin is our protective barrier from the outside world, and it is highly susceptible to damage. To prevent infection, restore protective skin cells, and reduce scarring, it is essential to quickly and robustly close a wound. A new study, published in Advanced Science, shows that a multi-axis stretchable wound zipper (MSWZ) is effective in closing complex wounds quickly, improving wound healing. The MSWZ uses programmable force that can be personalized via mobile application, enhancing patient comfort and compliance. https://medicalxpress.com/news/2026-06-programmable-wound-zipper-complex-skin.html Thu, 11 Jun 2026 03:10:01 EDT news700299601 There is a stark gap in how often hospitals screen older adults for postoperative delirium, with verified geriatric surgery programs screening nearly every patient while nonaccredited programs screen just half, according to new findings published in the Journal of the American College of Surgeons. This disparity may mean thousands of cases are going undetected and unaddressed. https://medicalxpress.com/news/2026-06-acs-geriatric-surgery-verification-hospitals.html Wed, 10 Jun 2026 14:20:01 EDT news700314721 A landmark clinical trial published in the New England Journal of Medicine found that tranexamic acid reduced transfusions across major surgeries without increasing the risk of dangerous blood clots. The trial was coordinated by the University of Manitoba (UM) and co-led by researchers at UM and The Ottawa Hospital. https://medicalxpress.com/news/2026-06-inexpensive-drug-major-surgeries-blood.html Wed, 10 Jun 2026 08:30:01 EDT news700216081 Researchers from LSU's Pennington Biomedical Research Center and collaborating institutions have found that Americans with the highest levels of obesity are undergoing fewer surgical procedures overall. These procedures include common operations like knee or hip replacement, hernia surgery, and surgery of the breast, prostate and colon—operations that are frequently done for cancer. https://medicalxpress.com/news/2026-06-americans-severe-obesity-surgeries.html Tue, 09 Jun 2026 15:40:01 EDT news700228021 A Concordia-led research team has developed a planning tool that could help hospitals book their operating rooms more efficiently, shorten wait times and better cope with last‑minute emergencies. The researchers developed their model using artificial intelligence tools to plan which operating rooms to open on each day, when each surgery should start and which cases may need to be delayed, all in a single, integrated framework. Their model uses far fewer variables than a widely used previous approach, making it faster and more practical for real hospital conditions, especially when dealing with dozens or even hundreds of operations in a week. https://medicalxpress.com/news/2026-06-tool-hospitals-surgical.html Thu, 04 Jun 2026 17:40:03 EDT news699805081 More adults are surviving both the wait for an organ and transplant surgery, but the number of people who need transplants continues to exceed the number of organs available, especially for kidneys, according to a national analysis published in the Journal of the American College of Surgeons. https://medicalxpress.com/news/2026-06-transplant-survival-shortages-persist-limit.html Thu, 04 Jun 2026 11:20:08 EDT news699789181 A pioneering clinical trial has successfully enabled two patients with end-stage kidney disease to receive previously improbable kidney transplants. These individuals were considered among the most difficult in the nation to match with a compatible donor kidney due to harmful antibodies they had developed ("sensitized"). https://medicalxpress.com/news/2026-06-car-treatment-door-patients-kidney.html Wed, 03 Jun 2026 17:00:05 EDT news699715466 Each year, about 250,000 Americans undergo sleeve gastrectomy, one of the most common weight-loss operations in the United States. For most patients, recovery is uneventful. But for a small share—between 1% and 3% in routine cases, and as many as 1 in 10 in revision surgeries—the procedure can leave behind a gastric leak, in which fluid escapes from the stomach and forms an abscess. https://medicalxpress.com/news/2026-06-3d-stent-lily-recovery-weight.html Wed, 03 Jun 2026 13:00:07 EDT news699708962 Tissue expansion is a common technique used in reconstructive surgery. Surgeons slowly stretch nearby skin to grow extra tissue that can be used to rebuild areas such as the ear, breast, or nose. https://medicalxpress.com/news/2026-06-custom-4d-implants-painful-path.html Tue, 02 Jun 2026 11:40:05 EDT news699617641
