[Late results of multistage polysegmental lung resection for tuberculosis at many sites].

The late outcomes of surgical treatment of 124 patients operated on for pulmonary tuberculosis at many sites were analyzed. Surgery was made in the anatomic variant of typical polysegmental resections involving 3 to 7 bronchopulmonary segments in combination with a number of additional elements. The stable cure rates were 77.7, 71.2, and 64.3% at 3-, 5- and 10-year follow-ups, respectively. The maximum relapse rates at 2- and 3-year follow-up were 9.5 and 9.2%, respectively with variations in some subgroups according to the type of resection, the clinical forms of tuberculosis, the bacteriological activity of the process by surgery and the drug resistance of Mycobacteria. The cumulative adjusted survival rates in the same periods were 92.1, 85.1, and 70%, respectively, with the maximum mortality rate (6.8%) at 3-year follow-up, they being ranged under the influence of the above risk factors. No systematic controlled preventive chemotherapy regimens are a cause of relapses and death in the late periods of follow-ups.
