AbstractBetween 1983 and 1988, 33 (21 men, 12 women) patients were treated for blunt diaphragmatic injuries following motor-vehicle (90%) or auto-pedestrian (10%) accidents at the Presley Trauma Center. Thirteen patients (39%) were right sided and 19 (56%) were left sided. One patient sustained bilateral ruptures. The mean Injury Severity Score (ISS) in both those that lived and those that died was not significantly different when right- and left-sided injuries were compared. Admission chest films were abnormal in 28 patients and diagnostic in nine patients (27%). The chest x ray was abnormal in 10 (78%) of those with right-sided injury. Twenty-three patients had diagnostic peritoneal lavage (DPL); 19 were initially positive, two were initially negative but became positive on relavage. There were two false-negative lavages. CT scan (4 patients) and barium enema (1 patient) were nondiagnostic. Diagnosis was delayed in four patients, two were diagnosed by repeat chest x ray and two by repeat lavage. All patients had multiple associated injuries, with 82 per cent having concomitant intra-abdominal injuries. All patients were explored via the transabdominal route. Complications occurred in 55 per cent and there were eight deaths (24%), all unrelated to the diaphragmatic injury. There was no relationship to mortality and hemidiaphragm injured. Chest x ray remains the single most beneficial diagnostic test for diaphragmatic injury. DPL is an insensitive test for isolated diaphragm injuries; however, the combination of CXR and DPL will lead to the diagnosis in the majority of cases. Ancillary radiologic tests are not beneficial. An elevated or obscured right hemidiaphragm should raise suspicion for blunt rupture.(ABSTRACT TRUNCATED AT 250 WORDS)
