Background: A traumatic diaphragmatic hernia (TDH) is a type of hernia that occurs as a result of a traumatic injury to the diaphragm. The present study was conducted to assess cases of traumatic diaphragmatic hernia (TDH). Materials & Methods: 75 cases of traumatic diaphragmatic hernia (TDH) of both genders were selected and the injury severity score (ISS), admission, mechanism of trauma, side, intestines henia, surgical procedure and length of the hospital stay (LOS) etc. was recorded. Results: Out of 75 patients, males were 40 and females were 35. In acute and chronic form, sideinvolved was left in 28 and 17 and right in 20 and 10. Admission was emergency in 34and 22 and outpatient in 14 and 5 respectively. Mechanism of trauma was blunt in 35 and 21 and penetratingin 13 and 6. Intestines henia was present in 10 and 19 and absentin 38 and 8 respectively. Surgical approaches was thoraco-abdominal in 8 and 4 and thoracotomy in 21 and 15 and laparotomy in 19 and 8 respectively. The difference was significant (P< 0.05). The mean LOS (days) was 42.6 and 13.2, length of the rupture was 9.6cm and 5.8cm and ISS was 25.1 and 10.7 in acute and chronic respectively. The difference was significant (P< 0.05). Conclusion: Chronic TDH is more likely to occur from milder trauma.To prevent a delayed diagnosis of TDH, individuals with periphrenic injuries must undergo a thoraco-abdominal computed tomography scan.
