Modern guidelines have identified thoracoscopic thymectomy as a preferable option for myasthenia gravis and non-invasive thymoma. In the era of the new coronavirus infection, it is relevant to develop protocols for anesthetic and perioperative support of patients undergoing thymectomy for myasthenia gravis after COVID-associated pneumonia (CAP). We present the results of thoracoscopic thymectomies in patients after CAP. Multidisciplinary team should determine therapeutic support, the need for plasmapheresis and thymectomy. Plasmapheresis and glucocorticosteroids are effective in addition to anticholinesterase therapy at the stages of perioperative support for correction of neurological status in patients with myasthenia combined with chronic obstructive pulmonary disease and pulmonary hypertension. Outpatient direct anticoagulants are advisable considering the need for prolonged postoperative prevention of thrombotic events.

Objective: To evaluate the quality of life before and after video-assisted thoracoscopic plication of relaxed dome of diaphragm., Material and Methods: The study included 17 patients operated on for unilateral relaxation of diaphragm. We analyzed quality of life in preoperative period, 1, 3, 6 and 12 months after surgery using the SF-36 and EuroQ-5D-5L questionnaires. To assess the impact of abnormality on respiratory function, we estimated diaphragm position, spirometry data and SGRQ scores., Results: FVC increased by 16.5% after 1 month, 19.5% after 6 months and 20.1% after 12 months. In addition, FEV1 significantly increased (by 12.6% after 1 month, 10.1% after 6 months and 12.7% after 12 months). Mean values of diaphragm elevation in postoperative period decreased by 25.5-25.6%. According to the SF-36 and EuroQ-5D-5L questionnaires, physical and psychological health components significantly increased within a month after surgical treatment. According to the SGRQ questionnaire, influence of disease on overall status decreased a month after surgery as evidences by lower total score ( p <0.05)., Conclusion: Objective and survey data revealed significant improvement in quality of life after surgery. A trend towards higher quality of life was demonstrated by all questionnaires in a month after surgery.

Objective: To present treatment outcomes in elderly and senile patients with cicatricial tracheal stenosis (CTS) and features of their perioperative management., Material and Methods: The study included 46 elderly and senile patients with CTS. We analyzed their gender and age, body mass index, etiology, extent and degree of stenosis, comorbidity index and ASA grade, postoperative complications according to TMM grading system., Results: Age of patients varied from 61 to 95 years (mean 66.38±8.65). Post-intubation stenosis was detected in 7 (15.2%) patients, post-tracheostomy CTS - in 39 (84.8%) patients (2 (4.3%) ones with tracheoesophageal fistula and 18 (39.1%) ones with tracheomalacia). CTS length ranged from 8 to 65 mm. The causes of invasive mechanical ventilation were traumatic brain and spinal trauma in 6 cases, emergency surgery in 11 cases and therapeutic diseases in 29 cases. CTS of cervical trachea was found in 21 patients, subglottic larynx and cervical trachea - 8 patients, cervical and upper thoracic trachea - 12 patients, thoracic segment - 3 patients, multifocal lesions - 2 patients. The Charlson index ranged from 5 to 12 points. ASA grade II was observed in 8 (17.4%) patients, III - 28 (60.9%), IV - in other ones. Circular resection was performed in 5 patients, laryngotracheoplasty - in 37 patients. CTS repair and tracheoesophageal fistula closure with laryngotracheoplasty were carried out in 2 patients. Postoperative complications occurred in 18 (39.1%) patients, mortality was 2.17%. In 21.7% of cases, complications were associated with tracheal suture. Endoscopic procedures, cryosurgery and hyperbaric oxygenation were used for correction. Good and satisfactory treatment outcomes were achieved in 86.5% of patients., Conclusion: Surgical treatment of CTS in elderly and senile patients requires participation of interdisciplinary team with special experience. Laryngotracheoplasty is safe and effective in these patients, and indications for circular resection are still limited.
