[POSTRESUSCITATION CICATRICIAL TRACHEAL STENOSIS. CURRENT STATE OF THE PROBLEM - THE SUCCESSES, THE HOPES AND DISAPPOINTMENTS.]

BACKGROUND Currently, the trend continues to increase the number ofpatients with cicatricial tracheal stenosis (CTS). Therefore, prevention and treatment ofthis disease remains topical. The main cause ofcicatricial tracheal stenosis is damaging the trachea during mechanical ventilation. The scheme ofprevention of this disease in Russia hasn't brought the desired results. THE AIM to clarify the modern etiology of cicatricial tracheal stenosis, to identify the trend in incidence rates, to determine whether there is an optimal safe alternative to tracheostomy including the use of minimally invasive techniques, to improve diagnostic and therapeutic algorithm at various stages of assistance, and also to study the results of innovative operations and new ways of maintaining gas exchange. MATERIALS AND METHODS 1128 patients with cicatricial tracheal stenosis was treated from 1963 to 2015 in Petrovsky National Research Centre of Surgery and IMSechenov First Moscow State Medical University. Over time methods of di- agnosis, methods of anesthesia and operations have been varied. In this regard all patients were divided into two groups depending on the period of time from 1963 to 2000 (297 patients) andfrom 2001 to 2015 (831 patients). In recent decades there is a steady increase in the number of treated patients. So, if in the first group during the year operational treatment about the CTS 8,0 patients were underwent, in the second - to 55.4. Cicatricial tracheal stenosis appeared after lung mechanical ventilation at 1025 (for 90.9%) patients. They have undergone both radical one-stage treatment and multi-stage and sequential intraluminal procedures. In general there is a clear trend towards more aggressive surgical tactics. So, if in thefirst group, the tracheal resection with anastomosis was performedin 59 patients only, the second-330. Thefrequency ofpostoperative complications and mortality in the second group ofpatients was 12.9 and 0.7 %, respectively. RESULTS Only a reasonable combination of all treatment methods, the principle of "every patient his own version of operation" allows to minimize the risk oftreatment and to get a good lasting result. Proof of such provision may be the fact that the frequency of complications and postoperative mortality at our patients have had a tendency to decrease and currently stands at 12.9 and 0.7 %, respectively for many years. It is 2.3 and 9.6 times less, respectively, than in the periodfrom 1963 to 2000. It appears that further reduction of these indicators will be at a slower pace, afurther solution of the CTS problem will be based on the prevention of disease. CONCLUSION Prevention of cicatricial tracheal stenosis in the departments of reanimation and intensive care is currently inadequate. It requires fundamentally new approaches, but reform still has not brought the desired results. Diagnosis of the CTS at an early stage allows early treatment and to avoid complex and risky operations. Increasingly important, apart tracheoscopy for diagnosis of tracheomalacia purchase dynamic computed tomography and magnetic resonance - tomography. Treatment ofpatients with CTS requires a multidisciplinary approach, individual selection operations for a particular patient. The general trend of the further development of tracheal surgery is associated with an increase in the number of simultaneous resections, including at the long, two-level stenosis, as well as at relapse. The patients who had refused treatment or have elected him palliative options made possible surgery. The frequency of postoperative comnlications and mortality decreased significantiv, including after extensive and traumatic operations on the trachea.
