It was day surgery for me. I had stones and those caused a blockage. To wait was to threaten the pancreas. It was done laproscopically.
My only issue was that the bladder leaked or burst, or something while being removed, so I had to wear a tube that was stuck somewhere in my guts for a couple of weeks to make sure no infection was developing. The tube drained clear fluid, so there was no problem.
Taking out the tube was a sensation and a half. It felt like my scrotum was being pulled through my belly button.
I've been able to eat normally starting shortly after the healing. It's been about 3 years now. No issues.
