While theroetically possible, intraperitoneal penetration by a liposuction cannula is a very rare occurrence. It is not a problem that I have seen or have heard of a specfic case but it undoubtably has happened somewhere. In experienced and qualified hands, this is a vert remote possibilily.
Then chances are low but disastrous if the cannula were to puncture any abdominal organs. This is why you always have your cosmetic procedures performed by an experienced board certified plastic surgeon!
