I also had high liver enzymes. Mine wasn't my gallbladder, though. Well, that's not quite right; it was my gallbladder, but by doing some specific things, I cleared up my pain and whatever was "ailing" my gallbladder and didn't have to do surgery.
What did I discover? I went to a naturopathic doctor and had him run lab tests. It was discovered that I had Severe Heavy Metal Toxicity that was making my liver work overtime, resulting in the high liver enzymes. Because the liver and the gallbladder work together, anything affecting the liver is also going to affect the gallbladder. I did 3 or 4 detoxes, flushed out the toxins and my liver, and my liver enzymes went down and my gallbladder was okay again (because the gallbladder got flushed out as well).
If you'd like to keep your gallbladder (because there is a reason it's in your body) and avoid surgery, I suggest contacting a Naturopathic doctor and finding out from him/her what could be causing the elevated/fluctuating liver enzymes and take the necessary steps to "cure" yourself.
One thing the allopathic doctors won't tell you is that, after you have your gallbladder removed, you SHOULD be taking enzymes for the rest of your life (you might even need to take enzymes now, if your body is deficient in some). Your gallbladder is there to help digest your food; without it, your body doesn't have certain enzymes it needs to digest your food properly. Therefore, things like cabbage or lettuce or beans or greasy/fried foods will be hard on your body, because your body doesn't have the necessary ingredients it needs (enzymes) to break the food down for your body to use. (In the case of my mom and dad, if they eat any of those foods it's an almost instanteous trip to the bathroom.)
You can heal yourself without surgery. Please look into alternatives.
