Excisional surgery for pulmonary tuberculosis was evaluated from the standpoint of work rehabilitation on almost 400 patients operated on during the period 1953 through 1957. The selection and preoperative preparation of patients is explained and the ancillary diagnostic benefits of thoracotomy are mentioned. This study revealed that in 97% of the patients followed tuberculosis has remained inactive, and that 370 of 378 patients whose tuberculosis has remained inactive were capable of employment. The salvage of military manpower for return to duty was significant, resulting in monetary savings by avoidance of pensions. There were three operative deaths within 30 days of surgery, one patient was never cured of her disease, two patients have died of tuberculosis, and there have been two other recurrences.
