Hello karenolac,
I have had laparoscopic surgery for endometriosis (had to remove an ovary). They will make about 4 small incisions on your abdomen. The naval slit is usually for the light. They will pump carbon dioxide in your abdomen to help push the other organs aside. When the surgery is over, they will try to get rid of excess carbon dioxide out of you, but they won't be able to get it all. So for a few days, the remaining carbon dioxide will cause pressure. That is best relieved by lying down, but some gentle movement (walking) is good to remove it too.
Depending on how much is done, expect soreness. And depending on how you respond, you may be able to go home the same day, I did. If you cough, sneeze,etc. place a pillow over your abdomen and press firmly but gently to help prevent too much sudden pressure on the surgical sites.
Good Luck!
