Does surgery leave any air bubbles inside the body?

I was wondering, when they open the body and sew it back together, how do they get rid of the air that would be introduced inside the body? If they can't remove it, does that pose any risk to the health of the person?

Yes surgery regularly leave air bubbles, and that is perfectly safe. 

Regular room air usually takes about a week to dissolve back into the blood, while gas from laparoscopic procedures which is CO2 dissolves a lot faster usually disappearing after 48 hours or so.

That is why people who have abdominal surgery commonly experience bloating sensation, or pain the shoulders after surgery. The shoulder pain is caused by diaphragmatic irritation, which the brain interpret as shoulder pain because your brain is not used to feeling anything like this from the diaphragm.
