Blunt injury to the diaphragm: an analysis of 44 patients

Forty-four patients sustaining blunt trauma with resultant diaphragmatic rupture during a 5 1/2-year period are presented. In 41 (93%), the diagnosis was established within 6 hours of admission. The correct diagnosis was made preoperatively in 19 patients operated on acutely (42%), in 22 (53%), ruptured diaphragm was an incidental finding at celiotomy or thoracotomy. The admission chest roentgenography, diagnostic peritoneal lavage, UGI contrast studies, and computed tomography were the most useful diagnostic aids. The transabdominal operative approach was utilized in 39 patients (89%). All patients had associated extra-abdominal injuries and 26 patients (59%) had associated intra-abdominal injuries. The mortality rate was 20.4%; early deaths were attributable to hemorrhage and severe head injury, late deaths to sepsis and progressive multiorgan failure.
