[Endoscopy-assisted dilatational tracheostomy in patients with COVID-19]. / Opyt endoskopicheski assistirovannykh dilatatsionnykh trakheostomii pri lechenii bol'nykh s COVID-19.

OBJECTIVE: To summarize an experience of endoscopy-assisted dilatational tracheostomies in patients with COVID-19. MATERIAL AND METHODS: There were 31 endoscopy-assisted dilatational tracheostomies in patients with COVID-19 for the period from April 17 to June 10, 2020 (11 women and 19 men). Mean age of patients was 66.7 years (range 48-87). Tracheostomy was performed using Ciaglia (22) and Griggs (9) techniques. All procedures were carried out at the intensive care unit in elective fashion. RESULTS: Tracheostomy was performed in 19.8% of ICU patients or 36.9% of all patients on mechanical ventilation within 6.5±2.5 days [min 3, max 11]. There were 22 survivors with tracheostomy (70.9%) that is comparable with survival of patients without mechanical ventilation (79.7%) and slightly higher than in patients on ventilation without tracheostomy (65.4%). No complications during the procedure were noted. CONCLUSION: Endoscopy-assisted dilatational tracheostomy is preferred for prolonged mechanical ventilation, including patients with COVID-19. The undeniable advantages of this operation are fewer intraoperative complications due to endoscopic control, and lower risk of tracheal strictures.

[Circular tracheal resection for acquired tracheal stenosis: evaluation of early and long-term outcomes]. / Tsirkuliarnaia rezektsiia pri rubtsovom stenoze trakhei: analiz neposredstvennykh i otdalennykh rezul'tatov.

AIM: To present single-center experience and results of surgical treatment of acquired tracheal stenosis. MATERIAL AND METHODS: There were 99 patients with acquired tracheal stenosis for the period from January 2008 to December 2017. Median age was 39 (28; 55) years (range 19-79 years), male/female ratio - 64/35. There were 59 patients with tracheostomy-related stenosis, 31 - post-intubation injury, 6 - posttraumatic stenosis, malignant and idiopathic stenosis was observed in 2 and 1 patients, respectively. Single-stage circular tracheal resection or staged surgical approach were preferred depending on localization and severity of stenosis, respiratory function at admission, severity of concomitant diseases and possibility of prolonged head adduction, presence of tracheostomy and cervical tissues inflammation, functional state of laryngeal structures. RESULTS: Single-stage circular tracheal resection was applied in 44 (44.4 %) out of 99 cases. In 55 (55.6%) patients staged approach was preferred: Montgomery T-tube placement followed by tracheoplasty after 6-12 months - 27 patients; tracheoplasty on prefabricated endotracheal stent - 8 patients; staged endotracheal treatment (including Dumon prosthesis deployment) - 12 patients. In 11 cases circular resection was done as a final stage of treatment. There was no in-hospital mortality after circular tracheal resection. Morbidity included anastomotic dehiscence - 2 (3.6%), recurrent stenosis in 6 months after surgery - 1 (1.8%), granulation tissue growth followed by stenosis - 4 (7.3%), wound infection - 3 (5.5%) cases), postoperative pneumonia - 2 (3.6%) patients, respectively. CONCLUSION: Tracheal resection is preferred for tracheal stenosis management. Alternative techniques are life-saving procedures, but could potentially extent the length of stenosis and delay recovery of the patient.

[Diagnosis and surgical treatment of adrenocortical cancer with invasion into great veins]. / Diagnostika i khirurgicheskoe lechenie adrenokortikal'nogo raka s invaziei v magistral'nye venoznye sosudy.

AIM: To estimate immediate and remote resaults of treatment of adrenocortical cancer with invasion into great veins. MATERIAL AND METHODS: It was analyzed survey and treatment results in 3 patients with adrenocortical cancer and invasion into renal veins and inferior vena cava. RESULTS: Radical surgery with tumoral thrombi removal from great vessels was performed in all cases. There were no complications and deaths in early postoperative period. Life expectancy after surgery was 6, 13 and over 58 months. CONCLUSION: At present time surgical intervention for adrenocortical cancer with invasion into great veins is single method to prolong patients' life.
