Gallstones and Gallbladder

One year back during Ultrasound I was found to have two small gallstones of 3mm dia while the common bile duct is said to be 4mm in dia. I have no problems except for two minor episodes of pain in right rib area. Pain has been tolerable. I also have type II diabetes. Doctors want that I should have the gallbladder removed. What is the harm if I do not remove the gallbladder? Could the stones pass thru the duct opening since the stones are smaller than bile duct dia?

I always had elevated bilirubin and was told it is Gilbert's syndrome. Will taking the gallbladder cause bilirubin level to go even higher? I was thinking that since the stones have not been bothering much - why go for a surgery.

If your gallbladder was to worsen it would effect the pancreas, i dont think that would happen anytime soon but its still a worry. My mom waited 10 yrs to have hers out and now shes had probs with her pancreas flaring up. I wouldnt worry right now about surgery but if  you started getting more attacks and more frequently then i would consider it.
