Penetrating chest injuries are a challenge to the thoracic or trauma surgeon. Penetrating thoracic trauma, especially that due to high-velocity gunshot wounds, is increasing at an alarming rate in our region. We report our experience with penetrating chest injuries mainly due to high-velocity gunshot wounds. During a period of 6 years we retrospectively reviewed the hospital records of 755 patients admitted to the Department of Thoracic and Cardiovascular Surgery, Dicle University School of Medicine, with the diagnosis of penetrating thoracic trauma. The mean age was 27.48 years, and 89-8% were male. The causes of penetrating injury were stab wounds in 45.3% and gunshot wounds in 54.7%. About 30% of the wounds were due to high-velocity gunshots; and among the gunshot wounds 56.2% were due to high-velocity shots. The most common thoracic injury was hemothorax (n = 190) followed by hemopneumothorax (n = 184). Isolated thoracic injuries were found in 53% of the patients. Nonoperative management was sufficient in 92% of the patients. Thoracotomy was performed in 8.1%. The mean duration of hospitalization was 11.2 days. The mean injury severity score (ISS) was 20.17 +/- 13.87. The morbidity was 23.3% and the mortality 5.6%. Fifty percent of all deaths were due to adult respiratory distress syndrome. Altogether 17% of patients with an ISS > 25 died, whereas only 0.9% of those with a score < 16 died. The mortality due to firearms was 8.95%. We concluded that in civilian practice chest tube thoracostomy remains by far the most common method of treating penetrating injury to the chest. The easy availability of high-velocity guns will continue to increase the number of civilians injured by these weapons.
