Multiple Stones In Gallbladder, Suggested Laproscopic Removal. Heartburn. No Pain Or Vomiting. Any Risk From Surgery?

Hi,
My wife is diagnosed with 3 gallstones in her gallbladder. 2 gallstones are of 4mm(millimeter) size and the 3rd one is of 8mm size. The doctor who diagnosed the scan report, says that the stones are at the neck of the gall bladder.
If the stone moves out of the gallbladder and blocks the bile duct, it will lead to severe pain and jaundice.
The doctor suggested removing the gallbladder laproscopically...

While I understand what the doctor said is right, I am still confused whether to go ahead with the surgery or not. My wife does not have any pain right now nor have felt any pain in the past in the abdomen or stomach or right side of the chest (below the ribcage) and no vomiting feeling. She does have heartburn (acidity) problems often which get well when takes antacid or pantaprazole... My wife also had a c-section surgery before 7 months during her pregnancy. Is it really good to remove the gallbladder with the current situation.. I am confused... please guide me... and let me know the post surgical risks if any....

Thanks,
Kasi
