Avoiding unnecessary bleeding during neuroendoscopic surgeries is crucial. When blood vessel location in a tumor cannot be visually confirmed, unintentional damage to the vessel and subsequent bleeding may occur. We propose a method for tumor blood vessel detection using a surgical robot system equipped with a force sensor in the gripper. Using this method, pulsation of a simulated artery inside a simulated tumor was detected by the force sensor, displayed as a gripping force wave.
Researchers compared treatment and survival rates between African American and white women following early detection with mammography of triple-negative breast cancer. African-American women have a higher rate of death from breast cancer compared with white women, a disparity partly explained by a higher rate of this aggressive breast cancer.
Researchers compared long-term quality of life and patient satisfaction among those patients who were treated with antibiotics or who had their appendix removed for uncomplicated acute appendicitis. Evidence in recent years has indicated antibiotic treatment is a safe and efficient alternative to appendectomy.
Tailoring care for older patients who have had emergency surgery can reduce complications and deaths, decrease the length of hospital stays and cut down on the need for alternate care at discharge, according to a new study led a University of Alberta researcher.
Researchers have examined new geriatric-specific characteristics that appear to raise the risk of elderly surgical patients having an unplanned hospital readmission within a month of initially leaving the hospital.
Scientists at Tokyo Institute of Technology designed a new type of controller for the robotic arm used in robotic surgery. Their controller combines the two distinct types of gripping used in commercially available robotic systems to leverage the advantages of both, reducing the efforts of the surgeon and providing good precision.
These evidence-based recommendations support closer follow-up after colonoscopy screenings for some groups, less intense follow-up for others, and provide guidance for removing colorectal polyps.
The Swedish team responsible for uterine transplantation research has, for the first time, transplanted a uterus from a deceased donor. The operation proceeded without complications and the recipient is doing well.
Average employer-sponsored insurance (ESI) spending rose to $5,892 per person in 2018, according to the Health Care Cost Institute's annual Health Care Cost and Utilization Report, which analyzes 2.5 billion medical claims to inform the public about trends affecting approximately 160 million US individuals with employer-sponsored insurance. This spending growth outpaced 2017's growth due to continued price growth combined with an uptick in utilization.
Thousands of UK children undergo unnecessary appendix surgery each year in the NHS, a new study reveals.
