Welcome to e health forum.
The chances for complications like incisional hernia, are very less likely, after a laparoscopic procedure, since, most of the abdominal supporting musculature and soft tissues are not cut, as in conventional open abdominal surgeries.
The swelling you feel are probably, signs of inflammation, associated with the slight tissue injury, that is common with laparoscopic surgeries. These changes usually are transient and would subside on their own, and do not need any specific treatments.
Application of ice packs, can help reduce the swelling and the discomfort if any.
In case, you have any doubts, consulting your operating surgeon, will help to provide more clear answers.
