In this paper we aimed to present our experiences on the cases of diaphragmatic ruptures which were seen generally with associated injuries. Hospital records of 75 patients were analyzed retrospectively in order to evaluate preoperative and intraoperative findings, and the results of their management. Eighty-seven percent of patients were male with a mean age of 32 years. Sixty-three percent of diaphragmatic injuries were secondary to penetrating trauma. The rate pfpreoperative diagnosis was found as 28 %, and of delayed diagnosis and treatment as 9 fo. lacerations were localized in the left hemidiaphragm in 50 (67 %) patients. The left hemidiaphragm harbored 82 % of blunt and 57 % of penetrating injuries (p=0.031). Associated injuries were determined in 84 % of our cases. Seventy-nine percent of the cases have grade 2 and 3 diaphragmatic lacerations. All ruptures, but one, have been repaired successfully with primary suture. The overall perioperative mortality was 9 %, and all of them were related to associated injuries. The mortality was 14 % after blunt, and 6 % after penetrating trauma (p=0.23). Preoperative diagnosis of traumatic diaphragmatic injuries is usually difficult. However the results of surgical repair of diaphragmatic lacerations is satisfactory. The death generally occurs secondary to associated injuries. To take into account diaphragmatic injuries after blunt or penetrating trauma of the thorax and the abdomen, and careful surgical exploration is essential for proper and successful management.
