What are common complications of appendectomy?

Infection: Appendicitiis is, by definition, an infection. Some patients may develop superficial skin infections following surgery. A deep infection or abscess may develop less frequently, especially following ruptured appendicitis. This requires abscess drainage, which may often be accomplished non-surgically.

And others: Less common problems can include bleeding, anesthesia related problems, and leak at the colon site where the appendix was removed. These are much less likely than infection after appendectomy. The earlier that appendicitis is diagnosed and treated the less likely you are to have complications from surgery.
