Hello and welcome to healthcare forum.
There is no option except surgery for complete cure of gall stone.
And as you are already diagnosed that you are having gall stones, you should go for surgery without any delay because if these stones enter the common bile
duct, you will develope obstructive laundice. And at that time will require emergency admission and an extra procedure known as E. R. C. P., alonge with surgery.
Best of luck.
