When they do DaVinci they pump CO2 into you to inflate the area to make moving around in there easier for them.. It has to process through the body to escape. It helps to walk a lot to get the gas passed out. They didn't want me to leave the hospital until I was passing gas and had several bowel movements. Hopefully, this is the case with you. If you did these things and they released you, then the best thing to do at this point is call your Dr., as has been said above. Good Luck.
