A gallbladder removal surgery is called a cholecystectomy and it can be performed in two ways. If your surgeon has performed it by laparoscopy, then recovery is quite fast. You will be sent home from hospital once you can eat and drink without feeling pain, and able to walk comfortably.
If gallbladder is removed by an open surgery, you will require hospitalisation for a few days, and some days to rest at home before you can resume all your normal activities.
