gallbladder removed ?

Should I have my gallbladder removed? I’m a healthy woman, age 52, with absolutely no digestive problems: no pain, no heartburn, no symptoms whatsoever. My ordeal began when a CT scan ordered as a follow-up to a routine colonoscopy revealed “an irregular enhancing appearance to the gallbladder wall especially in the region of the gallbladder neck”. A subsequent ultrasound was inconclusive: a “shading contrast” was noted but there was no mention of stones. My blood work revealed a slightly elevated liver & pancreas enzyme. My gastro doctor thought there was enough evidence of abnormality to refer me to a surgeon. He scared the heck out of me, because he seemed to think the problem may be something other than stones, such as scar tissue from repeated infections (which I’ve never suspected of having), or tumor (a very low probability). My surgeon thinks the shading referred to in the scans may be caused by stones on the order of a hundred or more. Both doctors recommend removal of the gallbladder but I am agonizing over the decision. On one hand, I feel like “if it ain’t broke don’t fix it” but at other times I worry that I have a serious, if silent, disorder.
