RESUMEN
Endoscopic approach with recanalization and stenting is one of the methods for cicatricial tracheal stenosis. Major complications may occur if service life of stents is not observed. However, there are currently no clear timing for stenting. In world practice, there are no indications on lifelong stenting for cicatricial tracheal stenosis. Restenosis is more common after stent removal and requires repeated stenting or another treatment. In case of prolonged stenting, silicone stent should be periodically replaced with a similar one due to destruction of silicone rubber. As a rule, this maneuver is necessary after 1-3 years. Currently, there is no information about maximum allowable duration of stent without replacement and possible complications. Condition of trachea after prolonged stenting is also unknown. We present long-term (27 years) tracheal stenting with a silicone stent. Stent fragmentation and dislocation throughout this period led to respiratory failure and emergency removal. Tracheal lumen was satisfactory immediately after procedure. However, restenosis appeared after 1.5 months and required endoscopic dilation with discussion of appropriate treatment option. However, the patient refused tracheal resection with anastomosis and underwent repeated stenting with similar stent and favorable immediate result.

Surgery for mediastinal tumors is still one of the most difficult in modern medicine. This is due to vital organs and various nature of tumors in this area. Teratomas are relatively rare among mediastinal tumors. However, they have certain features that is important for treatment strategy and management of possible complications. This can complicate diagnostic algorithm, exclude transthoracic biopsy and contribute to active surgical approach even for benign process. Oncogenesis of teratoma has its own characteristics. Tissues of different organs are always present in this tumor. Among these, pancreatic tissue inclusions are rare. A few data in the world literature on the treatment of such patients do not allow to develop a universally accepted algorithm of diagnosis and treatment. The authors present two patients with mediastinal teratoma. The second patient had teratoma with pancreatic tissue. The authors discuss the diagnostic algorithm for similar cases. A special attention is paid to description of possible complications throughout long-term follow-up period. Surgical aspects including the choice of access and local spread of process (adhesions in the area of surgical interest) are considered. The report on the treatment of two patients with rare mediastinal tumors containing pancreatic tissue will be useful for primary care physicians, thoracic surgeons, oncologists and morphologists.

Congenital anomalies of respiratory system are quite diverse and not all of them are subject to surgical treatment. One example is accessory lobe of the azygos vein. This anomaly usually has no clinical manifestations and requires only follow-up, as well as attention in surgery on the right half of the chest for some other disease. This situation changes when complications occur, for example, purulent-inflammatory process. Therapy is not always effective, and lung tissue destruction requires surgical treatment. Progressive destruction complicates diagnosis and choosing surgical tactics. We present a rare case of severe purulent-inflammatory complication with abscess in accessory lobe of v. azygos. Anatomical abnormalities following this congenital pulmonary anomaly can cause difficulties in surgeries for other intra-thoracic diseases. The situation is especially relevant for thoracoscopic access. This report will be useful for radiologists, pulmonologists and thoracic surgeons.

OBJECTIVE: To present modern aspects of improving surgical techniques in tracheal resection developed in recent years. MATERIAL AND METHODS: The authors have the most extensive experience in tracheal surgery (>2.000 patients over the past 50 years). Diagnostic capabilities, perioperative management and surgical techniques have changed over such a long period. This concerns the proposed classification of cicatricial tracheal stenosis, features of endoscopic and X-ray diagnostics, indications for various surgeries, choice of surgical approach, technique of tracheal tube mobilization and anastomosis after tracheal excision. Preventive measures for severe postoperative complications are described. CONCLUSION: Such an extensive experience allowed the authors to develop an algorithm for the treatment of patients with tracheal stenosis. This significantly reduced the incidence of postoperative complications and mortality. Replication of such equipment is associated with technical support of hospitals and professional level of specialists consisting of endoscopist, anesthesiologist, intensive care specialist and thoracic surgeon.

Modern approaches to intensive care and anesthesiology make it possible to save patients with various severe traumas. Prolonged mechanical ventilation allows stabilizing the patient's status, but can result severe complications including tracheoesophageal fistula. Our patient received severe combined injury after road accident, i.e. compression-comminuted fractures of DIV, DV, DVI vertebrae with spinal cord compression, ThIII compression fracture, compression-comminuted fracture of bodies and arches ThIV, V, VI with ThVI dislocation, lower paraplegia and pelvic organ dysfunction, left-sided laryngeal paresis, brain concussion and contusion of both lungs. Mechanical ventilation has been performed for 1.5 months. The patient suffered inflammatory complications: bilateral pneumonia complicated by right-sided pleural empyema, sepsis, tracheostomy suppuration followed by cervical soft tissue abscess. Pleural drainage and debridement, as well as drainage of abscess were performed. At the same time, we diagnosed external esophageal fistula at the CVII level. Tracheoesophageal fistula closure via cervical access was carried out at the first stage. Postoperative period was uneventful. After 20 days, we performed spondylosynthesis ThI-ThVII, and decompression laminectomy ThIV-ThVI. Spine stabilization by metal elements has a beneficial effect even without spinal cord recovery regarding better conditions for neurological and social rehabilitation. Thus, treatment was performed in a highly specialized multi-field hospital by thoracic surgeons and vertebrologists. We realized the treatment plan and obtained favorable results with minimal risk of postoperative complications.

Diagnostic and treatment algorithms for large mediastinal tumors are clear. However, long-term results are not always good. They largely depend on early diagnosis and morphological structure of tumor. Neoplasms may be asymptomatic for a long time, especially in case of slow growth. These tumors are usually diagnosed as soon as complications occur (for example, compression syndrome). Routine X-ray screening is rarer situation. Paraneoplastic syndromes are rare, and some ones are casuistic and unknown to surgical community. We describe the diagnosis and treatment of a patient with giant solitary mediastinal tumor complicated by hypoglycemic crises (Doege-Potter syndrome). This complication was life-threatening and required a multidisciplinary approach. Aggressive surgical approach cured the patient and returned her to normal lifestyle. The proposed algorithm for perioperative drug therapy was effective and deserves attention. This report will be useful for surgeons, oncologists, anesthesiologists, intensive care specialists and endocrinologists.

Laparoscopic surgery is now one of the main options for patients with surgical diseases of abdominal cavity, pelvis and retroperitoneal space. Postoperative complications are known, and methods for their prevention after such interventions are well developed. However, there are rare complications, and their management deserves a special attention. The authors present a patient with giant traumatic hernia in long-term period after laparoscopic liver surgery. Clinical manifestations of disease are retrospectively analyzed. The authors discuss surgical aspects of treatment, i.e. choice of access, repair of diaphragmatic defect and peculiarities of postoperative period associated with non-anatomic return of abdominal organs through the diaphragmatic defect. This report will be useful for radiologists, thoracic and abdominal surgeons, anesthesiologists and intensive care specialists.

OBJECTIVE: To describe treatment of cicatricial tracheal stenosis and tracheoesophageal fistula in patients with COVID-19 pneumonia. MATERIAL AND METHODS: There were 91 patients with cicatricial tracheal stenosis for the period from August 2020 to April 2022 (21 months). Of these, 32 (35.2%) patients had cicatricial tracheal stenosis, tracheoesophageal fistula and previous coronavirus infection with severe acute respiratory syndrome. Incidence of iatrogenic tracheal injury following ventilation for viral pneumonia in the pandemic increased by 5 times compared to pneumonia of other genesis. Majority of patients had pneumonia CT grade 4 (12 patients) and grade 3 (8 patients). Other ones had pulmonary parenchyma lesion grade 2-3 or mixed viral-bacterial pneumonia. Isolated tracheoesophageal fistula without severe cicatricial stenosis of trachea or esophagus was diagnosed in 4 patients. In other 2 patients, tracheal stenosis was combined with tracheoesophageal fistula. Eight (25%) patients had tracheostomy at the first admission. This rate was almost half that of patients treated for cicatricial tracheal stenosis in pre-pandemic period. RESULTS: Respiratory distress syndrome occurred in 1-7 months after discharge from COVID hospital. All patients underwent surgery. In 7 patients, we preferred palliative treatment with dilation and stenting until complete rehabilitation. In 5 patients, stent was removed after 6-9 months and these ones underwent surgery. There were 3 tracheal resections with anastomosis, and 2 patients underwent tracheoplasty. Resection was performed in 3 patients due to impossible stenting. Postoperative course in these patients was standard and did not differ from that in patients without viral pneumonia. In case of tracheoesophageal fistula, palliative interventions rarely allowed isolation of trachea. Four patients underwent surgery through cervical approach. There were difficult surgeries in 2 patients with tracheoesophageal fistula and cicatricial tracheal stenosis. One of them underwent separation of fistula and tracheal resection via cervical approach at primary admission. In another patient with thoracic fistula, we initially attempted to insert occluder. However, open surgery was required later due to dislocation of device. CONCLUSION: Absolute number of patients with tracheal stenosis, tracheoesophageal fistula and previous COVID-19 has increased by several times compared to pre-pandemic period. This is due to greater number of patients requiring ventilation with risk of tracheal injury, non-compliance with preventive protocol for tracheal injury including anti-ischemic measures during mechanical ventilation. The last fact was exacerbated by involvement of allied physicians with insufficient experience of safe ventilation in the «red zone¼, immunodeficiency in these patients aggravating purulent-inflammatory process in tracheal wall. The number of patients with tracheostomy was 2 times less that was associated with peculiarity of mechanical ventilation in SARS-CoV-2. Indeed, tracheostomy was a poor prognostic sign and physicians tried to avoid this procedure. Incidence of tracheoesophageal fistula in these patients increased by 2 times compared to pre-pandemic period. In subacute period of COVID-associated pneumonia, palliative measures for cicatricial tracheal stenosis and tracheoesophageal fistula should be preferred. Radical treatment should be performed after 3-6 months. Absolute indication for circular tracheal resection with anastomosis is impossible tracheal stenting and ensuring safe breathing by endoscopic methods, as well as combination of cicatricial tracheal stenosis with tracheoesophageal fistula and resistant aspiration syndrome. Incidence of postoperative complications in patients with cicatricial tracheal stenosis and previous mechanical ventilation for COVID-19 pneumonia and patients in pre-pandemic period is similar.

OBJECTIVE: To determine the optimal algorithm for tracheal anastomotic insufficiency and prevention of arterial bleeding. MATERIAL AND METHODS: We present 2 patients with defects of tracheal anastomosis after tracheal resection and divergence of tracheal edges. We primarily analyzed appropriate emergency care and prevention of subsequent severe complications such as arterial bleeding and respiratory insufficiency. CONCLUSION: Tracheostomy may be preferable for complete late tracheal anastomotic insufficiency to restore breathing. However, surgery should be accompanied by prevention of arterial bleeding. Isolation of damaged area, particularly tracheostomy tube, from the mediastinum by well-vascularized tissues can prevent bleeding from major vessels (for example, innominate artery). Follow-up is unreasonable due to worsening of clinical situation, risk of hemorrhagic complications and fatal outcomes. General satisfactory clinical status of the patient is not of matter. Repeated tracheal anastomosis is justified only for early insufficiency, i.e. within 2-3 days when postoperative inflammation is mild.

OBJECTIVE: To analyse safety and expediency of cardiac surgical technologies including cardiopulmonary bypass (CPB) in patients with locally advanced lung cancer and invasive tumors of the mediastinum. MATERIAL AND METHODS: Cardiac surgical techniques and CPB were used in 23 patients (group 1) with locally advanced thoracic tumors between 2005 and 2015. For the same period, there were 22 patients (group 2) who underwent combined surgeries and could have had similar techniques. However, these techniques were not used for various reasons. Mediastinal malignancies and non-small cell lung cancer were diagnosed in 26 (57.8%) and 19 (42.2%) patients, respectively. Invasion of superior vena cava (n=15), aorta (n=13) and pulmonary artery (n=12) was the most common. Lesion of innominate vein (n=8), left atrium (n=6) and innominate artery (n=4) was less common. A total of 21 pneumonectomies were performed (14 in the first group and 7 in the second group). Lobectomy was less common (one patient in each group). Sublobar lung resection was performed in 10 patients (2 patients in the first group and 8 ones in the second group). All resections were total in the first group (R0) that was confirmed by routine morphological examination of resection margins of different organs and vessels. The situation was worse in the second group (R1 in 19 (86.4%) patients, R2 in 3 (13.6%) patients). RESULTS: Total postoperative morbidity was 53.3%, mortality - 8.2%. These values are higher compared to patients undergoing surgical treatment for thoracic malignancies. Incidence of postoperative complications was higher in the first group (16 (69.6%) and 8 (36.4%), respectively). Four patients died in the first group. Sepsis (n=2), acute right ventricular failure (n=1) and acute myocardial infarction (n=1) caused death. There were no lethal outcomes in the second group. Various postoperative complications were diagnosed only in 8 (36.4%) patients. The long-term results were followed-up in 80% of patients. In the first group, 3- and 5-year survival rates were 30.5% and 25%, respectively (median 43.8 months). In the second group, these values were 25% and 2%, respectively (median 24.9 months). Long-term mortality in the second group was caused by progression of malignant process, including local recurrence, after palliative surgery (R1, R2 resection). CONCLUSION: Higher risk of postoperative complications and mortality in patients undergoing on-pump surgery is compensated by significantly better long-term results. Further progress is associated with higher safety of CPB, as well as solving some organizational and educational problems.

Tracheal and bronchial stenting is actively used for cancer and benign airway stenosis. This procedure is common in patients with advanced cancer. Stenting ensures breathing and availability of early chemo- and radiotherapy without the need for tracheostomy. This procedure is less common in patients with benign tracheal stenosis. In this case, isolated tracheal or bronchial stenting is performed. Complex tracheobronchial stenosis is extremely rare and creates significant difficulties. We present 3 cases of tracheobronchial stenting for cicatricial stenosis. In each case, stenosis was dilated with a rigid bronchoscope or balloon dilatation. Then, a silicone stent was installed. Resection with an appropriate anastomosis was contraindicated due to advanced pathological process. Thus stenting was regarded as a palliative operation. The follow-up periods were 9 months, 3 and 10 years. Each patient underwent inhalation therapy, endoscopy and repeated stenting if necessary.

OBJECTIVE: To determine the main forms of primary tracheal cancer (PTC), to specify the indications for various surgeries in these patients depending on extent and localization of lesion. MATERIAL AND METHODS: There were 263 PTC patients. Benign tumors were diagnosed in 68 (25.9%) patients, malignancies - in 195 (74.1%) cases. Tracheal cancer includes 3 basic morphological variants - adenocystic cancer (49.7%), carcinoid (18.7%) and squamous cell carcinoma (19.0%). Other forms of malignancies were much less common. We applied endoscopic intraluminal and open surgeries. In malignant PTC, open surgeries were performed in 165 (84.6%) out of 195 patients. Baseline palliative endoscopic treatment was performed in 30 patients. They underwent airway recanalization (with subsequent tracheal stenting in 19 patients). Endoscopic resection was preferred for benign tumors. RESULTS: Twenty (12.1%) patients died after open surgery, and 1 (3.3%) patient died after endoscopic procedure. Most lethal outcomes occurred in early years of development of tracheal surgery. The causes of mortality were tracheal anastomotic failure in 12 patients, pneumonia in 6 patients, and arterial bleeding in 2 patients. Severe postoperative period was observed in all 3 patients after tracheal replacement with a silicone prosthesis. Long-term treatment outcomes depended on morphological structure of PTC. Favorable results were observed in patients with neuroendocrine tumor (carcinoid), worse outcomes in adenocystic cancer and unfavorable results in squamous cell carcinoma (p<0.0013). Five-year survival rates were 75%, 65.6%, and 13.3%; 10-year survival rates were 75%, 56.2%, and 13.3%, respectively. These outcomes after combined treatment of primary tracheal cancer were significantly better compared to lung cancer (p<0.05 when compared to global data). CONCLUSION: Treatment of primary tracheal cancer should be based on classical principles of modern oncology (combined therapy, tumor resection with lymphadenectomy). Open and endoscopic interventions are justified. PTC is characterized by more favorable outcomes compared to lung cancer. It is difficult to analyze long-term results in tracheal cancer depending on various features of tumor process due to small number of observations. Accurate conclusions require multiple-center studies, preferably with international participation, which can convincingly prove certain concept.

Lung transplantations have been regularly performed in the Russian Federation since 2010. Therefore, the number of lung transplant recipients, as well as the number of patients with airway complications following lung transplantation has been increasing. Treatment of these patients takes place not only in transplantation centers, but also in other hospitals. This review is devoted to risk factors, clinical manifestations, treatment and prevention of airway complications after lung transplantation. We analyzed literature data over the last 15 years. It was confirmed that bronchoscopy is a «gold standard¼ for diagnosis of airway complications while bronchoscopic interventions are preferred for treatment. Balloon and rigid bronchodilation and endoscopic airway stenting are the most effective interventions. Silicone stents are the most optimal. Antimicrobial prophylaxis and timely use of antiproliferative immunosuppressive drugs are important factors in prevention and treatment of airway complications after lung transplantation.

OBJECTIVE: To analyze the long-term outcomes of local resections in patients with carcinoid tumors of bronchopulmonary system. MATERIAL AND METHODS: There were 52 patients with tracheal and bronchopulmonary carcinoid for the period 2013-2019. The sample included 21 men and 31 women. Age of patients ranged from 20 to 82 years (mean 62 years). Typical carcinoid was diagnosed in 34 cases, atypical carcinoid - in 18 cases. Central tumor was diagnosed in 26 patients. Tracheal neoplasm was found in 2 patients. Another patient had mediastinal tumor. Five patients underwent resection with broncho- or tracheobronchoplastic reconstruction. RESULTS: Surgical approach for carcinoid is determined by its differentiation, localization and lung tissue lesion following a long-standing tumor. These operations are quite safe. Complications occurred after 4 (7.7%) surgeries. Long-term results were followed-up for the period from 8 months to 7 years. There were no signs of recurrence and disease progression after organ-sparing bronchial resection. Local resection with bronchoplasty is advisable for typical carcinoid.

Postoperative drainage of pleural cavity is currently a common component of treatment of patients with surgical diseases of thoracic organs. Peculiarities of suctioning (aspiration parameters, passive drainage or active aspiration, the degree of discharge in the device-pleural cavity system, as well as the possibility of early patient activation, no need to «attach¼ him to the electric stationary suction) remain topical and continue to be discussed. New devices - aspirators, including mobile ones with digital control and rarefaction control component, appear in the market. MATERIAL AND METHODS: Between May and September 2021, 65 patients aged from 23 to 88 years with various oncological and non-oncological diseases of the thoracic cavity followed by drainage underwent resection operations with a volume less than pneumonectomy or lung decortication for empyema, parietal pleurectomy for recurrent pneumothorax. Six patients (4 after pneumonectomy and one with postoperative complications (1 after retoracotomy for hemothorax and 1 after laparoscopic cholecystectomy for acute destructive cholecystitis in the immediate postoperative period) were excluded from the study. The patients were divided into 2 groups. The first group consisted of 22 patients in whom in the early postoperative period we used continuous active pleural content aspiration with the help of high-tech mobile devices Atmos. The second group included 37 patients in whom we used drainage by means of medical suction of Lavrinovich or Visma-Planar design (Belarus). RESULTS AND CONCLUSION: Soft drainage by modern systems of pleural cavity content evacuation provides the best conditions for stopping air leakage from the lung tissue as well as for preventing pneumothorax when transporting a patient from the operating room and around the clinic for examination. The early activation of the patient with the connected mobile digital aspirator not only promotes the Fast-track surgery concept but also the ERAS program, i.e. accelerated rehabilitation, as recommended by the European Society of Thoracic Surgeons (ESTS). These designs also have advantages over stationary devices, such as subjective factors based on the relative ease of operation of mobile systems in their use, accessibility not only for medical staff, but also for the patient himself.

OBJECTIVE: To assess the tracheal elasticity and tracheal anastomosis tension for prevention of anastomosis-related complications and estimation of the maximum length of resection. MATERIAL AND METHODS: At the first stage, 20 patients with cicatricial tracheal stenosis underwent tracheoscopy in usual position, under maximum flexion and extension of the head for the period from September 2017 to December 2019. We measured the total length of trachea and length of stenotic segment. Tracheal extensibility was assessed considering the difference in measurements. At the second stage, anastomosis tension was intraoperatively measured using a dynamometer in normal head position, as well as at maximum flexion in 22 patients who underwent tracheal resection. Unlike multiple other studies, we studied tissue tension intraoperatively. RESULTS: Mean length of trachea was 12.8 cm, extensibility - 1.3 cm. Tracheal elasticity was greater in patients with a longer trachea and in patients under 40 years old. Mean length of resection was 3.9 cm (30% of mean length of trachea), anastomosis tension - 2.7 H or 270 g. Head flexion was followed by tension decrease by 0.7 H (26.9%), i.e. 70 g. This approach is less effective in case of resection of more than 30% of trachea length in a particular patient. CONCLUSION: Further experience in measurement of tracheal extensibility and anastomosis tension will make it possible to establish clinical significance of these indicators for prevention of complications.

OBJECTIVE: To analyze the long-term postoperative outcomes in patients with cicatricial tracheal stenosis and to determine the indications for various surgical strategies. MATERIAL AND METHODS: There were 976 patients with benign cicatricial tracheal stenosis for the period 2001-2017. Tracheal stenosis occurred after mechanical ventilation and tracheostomy in 910 (93.2%) patients. Other causes were neck trauma, burns, previous surgery or tuberculosis. Idiopathic stenosis was observed in 41 (4.2%) patients. Multiple-stage reconstructive treatment was possible due to benign nature of disease. There were 2.4 operations per a patient, and 976 patients underwent 2327 procedures. Circular tracheal resection was preferred (n=396). RESULTS: Surgical complications occurred in 107 (4.6%) cases, mortality rate - 0.3%. In long-term period, 42 patients died for various causes. In most cases (n=34, 80.9%), mortality was associated with concomitant diseases or consequences of trauma rather cicatricial tracheal stenosis or its treatment. Eight patients died from cicatricial tracheal stenosis or its treatment (7 patients after staged repair, 1 after circular tracheal resection). Four patients died due to asphyxia following T-tube obturation with a tracheobronchial secret or unjustified decannulation. For various reasons, 41 (6.2%) patients continued their treatment in other hospitals (4 patients died). Mortality rate in this group was 9.8%. Favorable long-term outcome was observed in 90.1% of patients, good and unsatisfactory results - in 7.2% and 1.8% of patients, respectively. Circular tracheal resection ensured better functional outcome. CONCLUSION: Surgical treatment of cicatricial tracheal stenosis is associated with low incidence of postoperative complications and mortality. However, further improvement in long-term results is associated with advanced rehabilitation programs for concomitant diseases. Treatment of cicatricial tracheal stenosis should be carried out at specialized hospitals.

Currently, a single classification of cicatricial tracheal stenosis is absent in national and world surgical practice. This issue is actual considering anatomical variability of tracheal structure in people with different constitutional features and previous complications. The proposed classification ensures individualized approach in surgical treatment of patients with cicatricial tracheal stenosis considering anatomical features in a particular patient.

OBJECTIVE: To analyze contamination of surgical wound during tracheal resection depending on the mode of mechanical ventilation. MATERIAL AND METHODS: There were 976 patients. Circular tracheal resection was made in 396 of these patients. RESULTS: Overall postoperative morbidity was 15.7%, mortality - 0.8%. Bacteriological examination of surgical wound was performed before tracheotomy and after formation of anastomosis depending on the method of mechanical ventilation. Surgical field was sterile before tracheotomy in all cases, contamination was confirmed after tracheotomy in all patients. Minimal contamination was observed in case of apneic oxygenation (100 times less than volumetric mechanical ventilation or high frequency mechanical ventilation). In all cases, several species of pathogenic microorganisms were identified. The number of species was also minimal in case of hypnotic mechanical ventilation. CONCLUSION: Contamination does not directly affect the development of local purulent-inflammatory process. However, this factor should not be ignored and compliance with all preventive measures is required.
