This business has me going back and forth as to the efficacy of gall bladder removal.
For example
I had two cholesteral gallstones and a third that passed through while I was in the hospital. The literature says that one or two gall stones may not merit a gall bladder removal.
(The doctors did say that my gall was completely black)
I discovered something huge. That is that cholesteral lowering drugs can cause gall stones. So I went off of them. I was taking colchesine, crestor and ezitimbe to reduce my stroke risk. But cholesteral lowering drugs also contribute to gallstones.
I think that the better strategy now is just to cut the last 10 pounds of fat around my guts. I’m on the way to doing that.
My stomach seems to have change. Coffee now disagrees with me. I’ve never had that before.
Cholesterol stones. These are usually yellow-green because they're mostly made of undissolved cholesterol. But they can have other stuff in them, such as bilirubin or bile salts. They're the most common, making up about 80% of gallstones.
Pigment stones. These are brown or black stones made mostly of bilirubin. People who get them usually have liver disease or a blood disorder such as sickle cell anemia or leukemia.

If your bile, and likely stones, are black, you may have a different issue than cholesterol stones.
Something to consider, if you go forward with the surgery:
