Acute appendicitis following abdominal trauma.

Acute appendicitis (AA) is generally considered to be a consequence of lumenal obstruction and inflammation of the appendix. At the beginning of the 20th century, trauma was considered to be one of the possible causes of AA but this relationship has not been examined much since then. Our experience with three cases of AA following blunt abdominal trauma led to an extensive review of the world literature on the subject. We believe that abdominal trauma might be causative of AA. The potential for this hazardous and easily missed diagnostic entity should be appreciated in cases of blunt abdominal trauma both for sound clinical decision making and for its potential medical and legal implications.
