[Surgical risk factors of complex polysegmental resections of lung for tuberculosis at multiple sites].

The results of 240 complex polysegmental resections of the lung for tuberculosis at multiple sites are analyzed. Surgical risk factors associated with additional surgical elements, such as expansion of an interventional area in the lung outside anatomic resection, traumatic elements of correction of volumetric ratios, and special procedures for isolating the lung from adhesions. Complex polysegmental resections as an anatomic variant without additional elements provide a high direct surgical effectiveness (95-100%) without deaths. The efficiency of complex polysegmental resections as a combined variant using additional elements reduces the effectiveness of treatment to 88% with 4.5-7.4% death rates in relation to the type of an operation. There is a high risk of postoperative complications in optional polysegmental and lobe + segment resections.
