Hello. welcome to HCM.
Treatment of already formed gall stones
is nothing but surgery. You are taking note of instances where people are not treated by surgery but there are umpteenth number of cases where cholecystectomy
(gall stone surgery) has healed people. Laproscopic or open surgery is a safe option.
Long standing gall stones may complicate issues by causing superimposed infection, perforation and even malignancy. So please be wise and judgemental for your benefit.
