For patients with chronic sinusitis and nasal polyps, nasal endoscopic surgery can remove polyps in a shorter time, with less intraoperative blood loss compared with traditional open sinus surgery, according to a study published online April 18 in BMC Surgery.

The first study evaluating Medicare patients undergoing percutaneous coronary intervention (PCI) in ambulatory surgery centers (ASCs) demonstrated good safety outcomes, such as mortality and adverse event rates at 30 days, compared to outpatient hospital departments, but were less likely to use certain technologies. The late-breaking data were presented today at the Society for Cardiovascular Angiography & Interventions (SCAI) 2025 Scientific Sessions.

Roughly nine in 10 patients awaiting organ transplants in the United States are waiting for kidneys.

Doctors have had to remove the pig kidney implanted in an American woman after her body rejected it, but her four months living with the animal’s organ set a record, the hospital that performed the operation said Friday.

Gastric bypass is the most clinically and cost-effective form of interventional surgery for people living with severe obesity, reveals new research. Results of the By-Band-Sleeve trial are published in The Lancet Diabetes & Endocrinology. The trial was led by the University of Bristol (U.K.).

Professor Rupert Pearse, NIHR Professor of Intensive Care Medicine from Queen Mary’s William Harvey Research Institute, and an international group of colleagues examined the records of 22,000 patients undergoing inpatient surgery across 17 Latin American countries. Their study found that 1 in 7 people developed complications after surgery, with 1 in 7 of those dying without ever leaving the hospital.

Researchers from NYU Abu Dhabi’s Advanced Microfluidics and Microdevices Laboratory (AMMLab) have developed an innovative sensing system that restores the missing tactile feedback in minimally invasive surgery (MIS), enhancing precision, ease of use, and safety. The new “off-the-jaw” system integrates force and angle sensors into the handle of laparoscopic tools, providing surgeons with real-time measurements of grasping forces and insights into tissue stiffness and thickness.

Almost half of children who require surgery for complicated appendicitis can safely complete their recovery at home, according to a new study.

Scientists at the Wisconsin National Primate Research Center (WNPRC) and the Morgridge Institute for Research at the University of Wisconsin–Madison have been at the forefront of stem cell research and regenerative biology since James Thomson isolated the first human embryonic stem cell in 1998.

Laparoscopic surgery, a minimally invasive technique, has transformed surgical procedures in high-income countries. This method, which uses a laparoscope to perform surgeries through small incisions, offers significant benefits such as reduced infection rates and quicker recovery times. Despite its advantages, laparoscopic surgery remains largely inaccessible in low- and middle-income countries (LMICs) due to the high cost of equipment and other logistical challenges.
