Gall bladder surgery is a tairly simple procedure. I have known a few folks that have had it done, but I have not.
Barring any complications, you should get to go home the same day.
I, however, had open heart surgery...they sawed my breastbone in half and put me on a heart/lung machine while they sewed veins harvested from my leg into my heart to bypass the clogged ones.
I spent 11 days in the hospital. ..and about 4 weeks after being sent home, I am still in some pain, feel weak and am not supposed to lift anything that weighs 10 to 15 pounds.
I am pretty sure that your recovery time will be much swifter than mine will be.
I hope all went well!
