[Repeated tracheal resection for non-neoplastic restenosis].

Treatment of patients with recurrent cicatrical tracheal stenosis after previous circular tracheal resection is one of the most difficult problems in thoracic surgery at present time. In most cases repeated radical surgery as new resection is declined in favour of palliative treatment. It is often associated with lingering or perpetual preserving of T-shape or tracheostomy tube and respiratory tract stenting. Development of thoracic surgery last years permits to perform repeated tracheal resections with restoration of respiratory tract integrity by using of new tracheal anastomosis. For the last 4 years 6 such operations were performed with satisfactory immediate and remote results. Diagnostic algorithm before repeated surgery is similar to those before primary intervention. Special attention should be attended to state of remained parts of respiratory tract, degree and length of stenosis and tracheomalacia which may be result of divergence of edges of the primary anastomosis. Preserving of not less than 1/4 primary length of intact trachea with its satisfactory mobility is main condition for this surgery because it will permit to perform new anastomosis without high tension. Risk of postoperative complications after repeated operations is not higher than those after primary resection. But at present time these operations are in competence of small number of specialists and medical institutions with serious experience in thoracic surgery.

[Surgical approaches in surgery for cicatrical tracheal stenosis].

At present time several surgical approaches are being used for cicatrical tracheal stenosis including cervicotomy, longitudinal- circumferential sternotomy and thoracotomy. Besides location of stenosis an approach is being determined by constitutional and anatomical features of patient, surgeon's and anesthesiologist's experience, well-coordinated work of operating team. If pathological process is placed in cervico-laryngeal, cervical and upper thoracic segment cervicotomy is preferable. Partial longitudinal-circumferential sternotomy is believed to be adequate in case of lesion of thoracic trachea and its bifurcation. This approach provides all types of tracheal reconstructions. Technical difficulties appear if process is localized in membranous wall of suprabifurcational part, bifurcation and primary bronchus. In these cases we recommend thoracotomy through the bed of resected the 3rd or the 4th ribs and patient's position on his front. Interventions including pulmonary tissue resection and tracheal edges convergence are possible through thoracotomy.

[Surgery of the diaphragm in the planned thoracic surgery].

122 patients with different diseases of the diaphragm were operated on during 1963-2011 yy. The majority of patients - 76 (62.3%) - had hernias of the weak phrenic zones. 14 (11.5%) and 17 (14.0%) patients had posttraumatic hernia and phrenic relaxation, respectively. The majority of patients had no complaints and the disease was diagnosed on the X-ray examination. Rarely, the compression syndrome, caused by the translocation of the bowel into the thoracic cavity, was registered. That clinically emerged as short breath, heaviness sensation and cardiac rhythm disorders. The worked out reconstructive operations allow to cure such patients with minimal risk.

[Surgery for lung cancer in elderly].

The growth of malignant tumors of lungs among elderly patients together with overall increase of people older then 70, aroused new problems in surgery and anesthesiology. Nowadays, modern medicine succeeded minimal postoperative mortality and lethality among such patients, 19,7 and 6,4%, respectively. 3 and 5-year survival among operated patients was 68 and 42%. Actually, overall lethality rate was determined mainly by relative and conquering diseases. Lobectomy should be considered a method of choice, although sublobar resection is appropriate by lung tumors of stages 1 and 2.

[Surgical treatment of bronchiolo-alveolar cancer].

Bronchioloalveolar cancer (BAC) belongs to a high- grade differentiated lung adenocarcinoma, localizes in peripheral parts of the lung and demonstrates an intraalveolar growth. 21 patients with BAC has been operated during the period of 1968-2008yy. It comprised 0,5% of the whole amount of patients operated on lung cancer. Diagnostics of BAC, especially its pneumonia-like form, is considered to be challenging and often belated. Though it was retrospectively proven, that BAC is characterized by a slow growth and rare involvement of lymph nodes. Lobectomy is considered to be a method of choice for the surgical treatment. Long-term treatment results are somewhat better then of other forms of non-small cell carcinoma of lung: of 21 radically operated patients, 11 are alive.
