Penetrating trauma of the lung.

Records of 373 patients with penetrating wounds of the lung seen at the Ben Taub General Hospital over a 1-year period were reviewed. Intercostal tube thoracostomy was the only therapy required in 282 patients. Thoracotomy was performed in 91 patients with repair of a pulmonary lesion in only 45 patients. Pneumonorrhaphy was performed in 33 patients, segmentectomy in six, and lobectomy in two. Four patients required repair of tracheal injuries. Fourteen patients initially treated with intercostal tube drainage required thoracotomy for complications of clotted hemothorax in eight and empyema in six. There were 29 deaths. Penetrating lung trauma in the majority of patients may be treated conservatively with a low incidence of infection or complication. Of the patients who require thoracotomy, associated injuries will frequently represent the major operative indication. Early thoracotomy for complication of clotted hemothorax or empyema is encouraged.
