MD here. A lot of misinformation in these responses. Red blood is not only from close to the anus. Bright red blood (hematochezia) is generally associated with lower GI origin, which includes all of the colon. And it is definitely one of the presenting symptoms of colon cancer.

Yes, it is also associated with hemorrhoids. And in a 20 year old, that it a higher on the differential. But it should still be checked out. Which means a visit where someone actual does an exam and confirms you have hemorrhoids, or an additional workup (e.g. colonoscopy) if no hemorrhoids are detected. There are other explanations for bleeding that may be common in younger people, and also associated with irregular bowel habits, such as inflammatory bowel disease (Crohn's and ulcerative colitis). And if I saw a 20 year old with irregular bowel habits, bleeding and abdominal pain, that would be my working diagnosis. A colonoscopy will work to evaluate for that, as well.

Bottom line: If you are having bleeding associated with bowel movements, do not write it off.

With large floor buffer and a mastic removal wheel.

If you're question is "Can I remove this stuff and get to 'nice' floors with no additional steps?", then the answer is most likely "No". Once you get that stuff up, the floors are going to need to be refinished.

Are you going to have someone else refinish them? If so, I'd just have them handle it. If you're going to refinish them yourself, you'll end up having to rent a machine to do it anyway. Call around to local tool rental places. Your local big box might have them, but the independent/dedicated rental outfits are often more helpful if you tell them what you're trying to do and they can get you the right stuff.

It's certainly a game changer for Intuitive's stock price.

I'm a surgeon, and I use the DaVinci. Yes, it's cool. But there remains a narrow range of things where it offers benefit (we can argue about how that's defined) over straight stick laparoscopy. You can basically break it down into:

  • Procedures where laparoscopy has a steep learning curve, but robotics offer a potentially shorter learning curve making it more realistic for broad dissemination.
  • Procedures where laparoscopy may be possible, but more complex cases are still challenging except for the most technically proficient. In these cases, robotic approaches may facilitate a minimally invasive approach.

There are harder to measure benefits related to ergonomics and surgeon perception of how the robot makes some things easier. But this doesn't always translate into a measurable patient benefit, while still carrying cost. The application of remote operation could eventually be interesting.
