Robotic surgeon successful in first prostate snip

Igor Stravinsky

We've been doing these surgeries in the rather backward area I live in the US for about 2 years, although the million dollar robot is used. The operations are substantially longer than the version using a large incision, although the post-op pain is better and recovery faster. The robotic version also requires the patient to be placed in an extreme head-down position during surgery, leading to fluid accumulation around the face, tongue swelling, and increased risk of breathing problems after anesthesia.

Ignore the poster who says prostate CA is nothing to worry about. True, most elderly men have evidence of the beginnings prostate CA. The problem is that it is difficult to determine whether abnormal prostate cell growth will spread or not. Death by prostate CA is rather unpleasant (it likes bone, and can cause terrible back pain and fractures).

Case Control Study

This seems to be a case-control study. In medicine, such studies are easier to do than randomized controlled trials, but they are also fraught with shortcomings, namely they only detect correlation, not causation.

To prove their thesis, the authors should perform a randomized controlled trial. Enroll 1000 people, randomly give 500 guns, and see what happens. (If they wanted they could then do a crossover - switch the guns from the 500 who have them to the 500 who don't, and record again what happens).
