Abstract
Introduction: The purpose of this study was to describe the postoperative changes in lung function after pure open lobectomy for lung carcinoma. Methods: 30 patients (mean age 64 ± 7 years old, 16 men and 14 women) underwent a left or right lobectomy. They underwent spirometric pulmonary tests preoperatively, and at 1 and 6 months after the operation. Results: The average preoperative forced expiratory volume in 1 second (FEV1) was 2.55±0.62lt and the mean postoperative FEV1 at 1 and 6 months was 1.97 ± 0.59 L and 2.15±0.66 L respectively. The percentage losses for FEV1 were 22.7% and 15.4% after 1 and 6 months respectively. An average percentage increase of 9.4% for FEV1 was estimated at the time of 6 months in comparison with this of 1 month after the operation. The average preoperative forced vital capacity (FVC) was 3.17 ± 0.81 L and the mean postoperative FVC at 1 and 6 months after the operation was 2.50 ± 0.63 L and 2.72 ± 0.67 L respectively. The percentage losses for FVC were 21.1% and 14.2% after 1 and 6 months respectively. An average percentage increase of 8.7% was observed at the time period of 6 months in comparison with this of 1 month after the operation. Conclusion: Although, we observed a significant decrease in FEV1 and FVC after the operation, all patients were in excellent clinical status. FEV1 and FVC of 6 months were increased in comparison with the respective values of 1 month after the operation, but did not reach the preoperative values in any patient.

Summary
The purpose of this study was to describe the postoperative changes in lung function after pure open lobectomy for lung carcinoma. Methods: 30 patients (mean age 64 ± 7 years old, 16 men and 14 women) underwent a left or right lobectomy They underwent spirometric pulmonary tests preoperatively, and at 1 and 6 months after the operation. FEV1 and FVC of 6 months were increased in comparison with the respective values of 1 month after the operation, but did not reach the preoperative values in any patient. Lung resection offers the best prospective for long-term survival in patients with nonmetastatic bronchogenic carcinoma.[1] the removal of lung parenchyma from patients with lung carcinoma, who are usually smokers with an already compromised pulmonary status, may lead to respiratory failure For these reasons, it is imperative to determine the operability of these patients in order to predict residual respiratory function after surgery. With the present study we aimed at to describing the postoperative changes in lung function after pure open lobectomy for lung carcinoma
