Perforation of the colon after blunt trauma.

Blunt rupture of the colon follows a direct blow to the abdomen. Physical findings suggesting peritoneal irritation are usually present early in the postinjury period and lead to further evaluation and operation. In unresponsive patients, physical findings may be masked, diagnosis delayed, and outcome compromised. Perioperative antibiotics and early celiotomy with complete intra-abdominal exploration and primary repair of the colon injury usually provide excellent results.
