RESUMO
Lobectomy is the operation of choice for many diseases of pulmonary pathology, lung cancer being the most frequent indication to it. Smoking, as a common etiological factor, leads to a frequent combination of chronic obstructive disease of the lungs (CODL) and lung cancer. The expected disturbance of lung function after operation in such patients can make it not necessary. However, the functional results of lobectomy in CODL patients still remain not studied. The aim of this prospective investigation was to study effects of lobectomy in patients with diseases of the lung parenchyma without hypoventilation or partial atelectasis. 76 patients were divided into 2 groups: 35 patients with CODL and 41 patients without CODL. In patients with CODL after lobectomy the external ventilation function was less affected than in patients without it. The generally accepted formula for the calculation of the postoperative VFE 1 reliably increased the prognosed reduction of this index. Reduction of the indices of the external ventilation function after lobectomy was less pronounced in patients with the medium and severe degree of CODL.
