The records of 14 patients with traumatic diaphragmatic rupture seen at Dongguk University Hospital from February 1992 through December 1995 were reviewed. Ten patients were male and four were female(M:F=2.5:1). The age distribution ranged from 17 to 73 years with the mean age of 41.7 years. The 14 patients included 12 who had blunt trauma(traffic accident 11, crushing injury 1) and 2 with penetrating diaphragmatic rupture(stab wound 2). Of those 12 blunt trauma, 7 patients(58.3%) were left sided and 5(41.7%) involved the right hemidiaphragm. The diagnosis was made preoperatively in 8 patients (57.1%) and during surgery in 6(42.9%). All right-sided injuries were repaired through a thoracotomy and left-sided defects were corrected through a laparotomy in 6, laparotomy and thoracotomy in 1. There were 2(14.3%) operative deaths that were caused by myocardial infarction and the sequelae of combined injuries.
