Should I have gall bladder surgery

I have biliary dyskinesia and my ejection rate of the gall bladder is 10%. I am contemplating gall bladder surgery. My diet consists mainly of low fat foods. However, I have a pain in the stomach area usually after every meal. I can have a small low fat food portion in the middle of the day and still get this pain. Since my symptoms are not classical for my condition, I am not sure whether gallbladder surgery will help with my symptoms. An interesting note is that the pain eases and sometimes goes away when I chew gum. So and ideas whether surgery will help.
