| Summary: | Objective. To determine the optimal regimes of application of a low-temperature electric welding of soft living tissues in formation of suture in pulmonary parenchyma, the pulmonary hilum preparation, and its lymph nodes ablation, basing on microbiological estimation of action of various regimes on the tuberculosis mycobacteria and densitometric indices of pulmonary parenchyma and to estimate its efficacy in far remote postoperative period.
Materials and methods. The work is based on the results of postoperative investigations in 275 patients with the aim to determine the impact of a low-temperature electric welding of soft living tissues on pulmonary parenchyma and mediastinal lymph nodes.
Results. There was established, that application of minimal automatic regime of a low-temperature electric welding of soft living tissues in phthisiosurgery guarantees effective elimination of microflora in 98.3% of patients. The revealed emphysematous processes and fibrous changes are occurring in parallel and essentially impacts the development of pulmonary-pleural complications. Conventional density of pulmonary parenchyma was noted in 57.5% of patients in the investigation group and in 49.7% patients of the control group. In both groups, the enhanced superdensity of pulmonary parenchyma in far remote postoperative period was not observed. Density of mediastinal lymph nodes was compared, and statistically significant difference between densitometric indices of mediastinal lymph nodes was absent. While application of a low-temperature electric welding of soft living tissues in minimal power regime of the complex there was noted essential characteristic as well: lesser rate of fibrous transformation of pulmonary parenchyma, than in the control group – in 13.3 and 15.5%, accordingly.
Conclusion. Application of a low-temperature electric welding of soft living tissues in phthisiosurgical interventions for the lymph nodes ablation have shown the presence of effective bactericidal regimes with preservation of lymphatic circulation, and low rigidity of pulmonary parenchyma in postoperative period. While a low-temperature electric welding of soft living tissues applied, the signs of lymphostasis, the lymphatic outflow disorders and pulmonary-pleural complications in postoperative period after phthisiosurgical interventions with the lymph node ablation procedure do not occur, as well as the risk of iatrogenic damages while performing dissection and excision of mediastinal lymph nodes. |
