We present a case of sigmoid colon injury after blunt abdominal trauma. The patient was submitted to sigmoid resection with primary end-to-end colo-colic anastomosis. He died 22 days after operation with septic shock and acute respiratory failure. Post-mortem examination showed left lung generalized pneumonia with no signs of intra-abdominal pathology; colo-colic anastomosis was intact. We reviewed the literature about the management of this rare trauma.
