A study by Johns Hopkins researchers found that videotaping surgeries can improve outcomes in radical prostatectomy. The study, which involved 62 patients, showed that minor differences in surgical techniques can have a major impact on results. Surgeons who perform successful procedures should review the footage to identify key factors.
Research suggests that men with high HDL cholesterol levels after coronary bypass surgery live longer and experience fewer cardiac events. High levels of HDL cholesterol may be more significant than LDL in predicting long-term outcomes for patients undergoing heart surgery.
Researchers found that men with low HDL levels had nearly twice the mortality rate as those with higher levels after coronary bypass surgery. High HDL levels also helped clear bad cholesterol from the blood and protected against heart disease.
Lung cancer treatment disparities between blacks and whites are attributed to racial attitudes and biases, affecting surgical resection rates and survival outcomes.

Patients who received amiodarone experienced less discomfort, shorter hospital stays, and lower hospital costs compared to those who received a placebo.
A new study by Thomas Jefferson University finds that traditional criteria for stroke-preventing surgery may overestimate men's risk and underestimate women's risk due to smaller carotid arteries. The 70% blockage threshold may need to be adjusted to account for these differences.
Studies of over 25,000 Emory angioplasty and coronary bypass patients reveal significant improvements in patient outcomes, including shorter hospital stays and decreased mortality rates. Hospital costs also decreased by 30% between 1988 and 1996, with a notable reduction in the last two years.
A new study of over 1,000 prostate cancer patients found that those who underwent surgery had remarkably good outcomes, with few reporting dissatisfaction or problems with urinary or sexual function. Despite fears about complications, most men felt healthier and satisfied with their treatment after surgery.
The FDA has cleared Cook's low-profile GR II Coronary Stent, allowing cardiologists to treat blockages in hard-to-reach blood vessels without bypass surgery. This new stent could benefit thousands of U.S. heart disease patients who previously required heart bypass surgery.
The newly revised nomograms combine clinical stage, Gleason score, and PSA level information to identify men who can be cured by surgery alone. The use of these nomograms should improve our ability to predict surgical curability and help patients make informed treatment decisions.
Maintaining a surgical patient's normal body temperature has been shown to reduce infections, speed healing and shorten hospital stays. Results of a clinical trial suggest a 55% risk reduction in cardiac complications when near-normal body temperatures are maintained.
Research shows music can decrease cardiovascular stress and improve coping abilities for patients undergoing ambulatory surgery. Music-listening patients reported lower stress levels and better coping mechanisms than those who did not listen to music.
A recent study published in the New England Journal of Medicine found that blacks are less likely to undergo heart bypass surgery compared to whites. The research suggests that patient preferences and cultural factors contribute to this disparity in treatment.

The report's authors argue that closing the credibility gap between clinicians and public data is vital for improving quality.
A multi-institutional study found that surgery is effective for localized prostate cancer, with tumor grade being the best predictor of long-term survival.
