New Imaging Technique May Enhance Accuracy of Cancer Surgery

Use of a chemofluorescence technique may allow surgeons to visualize, in real time, cancerous tissue, thereby increasing the precision of their resections, according to animal study findings presented Tuesday at the National Meeting of the American Chemical Society in Philadelphia.

New Risk Factors for Cardiovascular Problems After Joint Surgery Identified

In addition to confirming previously identified risk factors for cardiovascular complications after total joint replacement (TJR) surgery, researchers have shown that bilateral and revision operations are associated with increased risk. "Revision joint replacement and bilateral surgery are much more prolonged operations than primary unilateral joint replacement," Dr. Jeffrey N. Katz, from Brigham and Women's Hospital […]

Plasma DNA More Reliable Than CEA for Detecting Recurrent Esophageal Cancer

Elevated free plasma DNA is a reliable indicator of recurrent esophageal cancer, more so than carcinoembryonic antigen (CEA), and is able to detect recurrent disease in most patients before clinical evidence emerges. These findings come from a study by researchers at the University of Southern California, published in the July issue of the Journal of […]

Video Games Enhance Skills of Laparoscopic Surgeons

Laparoscopic surgeons who play video games requiring spatial skills and dexterity are faster and less prone to error when performing advanced surgical procedures, researchers reported on Sunday at the Annual Convention of the American Psychological Association in Boston.
