No dependable test exists for diagnosis of diaphragmatic injury in asymptomatic patients with thoraco-abdominal stab wounds. Forty-one consecutive patients with anterior stab wounds of the lower left chest were treated in a 30-month period. In the 21 patients seen during the first 15 months, operations were reserved for those with peritoneal signs or continuing blood loss. ⋯ The true incidence of occult diaphragm injuries may be underestimated. In the prospectively studied group, the policy of routine celiotomy for anterior stab wounds of the lower left chest resulted in recognition and repair of a fivefold greater number of isolated diaphragm injuries. In the absence of a reliable, noninvasive test to diagnose penetration of the diaphragm, celiotomy should be considered in light of the risks of late strangulation.
