Major bowel and diaphragmatic injuries associated with blunt spleen or liver rupture.

The incidence of major bowel and diaphragm injuries occurring in association with blunt spleen and liver ruptures in adults was studied. Of 142 patients with splenic injuries, five had major bowel injuries and 12 had diaphragmatic ruptures. Of 102 patients with blunt hepatic injury, 13 had either bowel or diaphragm ruptures or both. Six bowel and diaphragm injuries occurred in 42 patients with blunt ruptures of both the liver and spleen. Anatomically minor spleen injuries were associated with a 4.8% risk of bowel or diaphragm rupture. Anatomically major splenic lacerations had associated bowel or diaphragm wounds in 16.4% of cases (p = 0.024). A 20% incidence of partial-thickness bowel wounds was found in patients with hepatic or splenic injury, but the natural history of these wounds is unknown.
