AbstractNo 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. Ten of these 21 patients (48%) required celiotomy; 2 patients (10%) had isolated diaphragm injuries and there was one negative celiotomy. Of the eleven patients who were not explored, 2 (18%) returned within 18 months after injury with an incarcerated diaphragmatic hernia. During the subsequent 15 months, the next 20 patients were managed by routine celiotomy in a prospective study. The admission systolic blood pressure and incidence of pneumothorax, celiotomy, diaphragm injury, isolated diaphragm injury, and unnecessary celiotomy in these two groups were compared. Ten patients in the prospective group (50%) were found to have isolated diaphragm injuries (P less than 0.005) and 7 (35%) had negative celiotomies (P less than 0.02). 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.
