How To Treat Minimal Functioning Of Gall Bladder?

SO my gallbladder Is only working 13% out of 30% my doctor told me but that was a little over 7 months ago. He also diagnosed me with IBS (irritable bowl syndrome.) and a hole in my liver. My pains haven t gone away with the meds he s requested me to take. nothing he gives me seems to work. I was wondering what could happen if I don t get my gallbladder removed?
