Hi if there is no upper abdominal pain / post meal fullness / discomfort / upper back pain , then you don't require surgery. This is asymptomatic gall bladder. In case you develop any of above symptoms them you require surgery. You can read my article on Practo- Gall bladder stone.feel free to ask any further quary.
Next Steps
Gall bladder polyp more than 1.5 cms require removal as chances of cancer increases by 2 fold.
