Yes, but don't panic. It helps your surgeon see things as he works laparoscopically. I didn't know about it either and I Just wanted to make sure you knew.
I am on day 5 post op. Did you talk to your doctor about the gas? They fill up your belly with gas, and it took 3 days for me to expel it. There is very little pain from the surgery itself, but the gas was a different story for me. Very painful. Keep on the liquids, no matter what.
