The Thoracic Department, Yarutsk Research Institute of Tuberculosis, has developed a new method for extrapleural plastic repair of the apex of the lung in destructive tuberculosis. The essence of the method is that pneumolysis of the apex of the lung and its bringing down is made by the well-known procedure described by L. K. Bogush after thoracoplasty. To prevent its expanding, the apex of the lung is fixed by a hammock mesh prepared before surgery. For this, No. 2 polysorb thresh is used and a 10 x 14-cm mesh is woven. The cells measure 2 x 2 cm. Then the mesh is placed in disinfectant solution. Surgery was performed in 41 patients with generalized fibrocavernous, disseminated, cavernous, and infiltrative pulmonary tuberculosis, by yielding 90.3% efficiency. The developed operation may be used during a non-stabilized tuberculous process, anterior and upper lung destructions and in the presence of a giant cavity in the lung tissue. The time course of changes in the indices of external respiratory function is indicative of a more rapid and qualitative recovery of the external respiratory apparatus and of a rapid adaptation of compensatory respiratory mechanisms in the postoperative period.
