Wait and see.
The presence of gallstones
in the absence of symptoms does not warrant gallbladder surgery.
In fact, most people with "silent" gallstones will never develop symptoms, as high as 75% of the time. I advise my patients to be familiar with the symptoms of gallbladder disease and return if these develop. While surgery is safe and easy, it is not risk-free; in this situation , doing nothing is safest.
