[Combined thoracoplasty using titanium mesh implant in patients with total sternal instability following postoperative sternomediastinitis]. / Kombinirovannaia torakoplastika setchatym titanovym éndoprotezom u patsientov s total'noi nestabil'nost'iu grudiny v iskhode khronicheskogo posleoperatsionnogo sternomediastinita.

OBJECTIVE: To analyze the results of chest wall reconstruction with titanium mesh implant in patients with total sternal instability following postoperative sternomediastinitis. MATERIAL AND METHODS: There were 100 patients with total sternal instability for the period from January 2016 to December 2018. Median of age was 62 (58; 68) years. Male/female ratio was 82/18. All patients were treated in accordance with standardized protocol. Postoperative complications were assessed using Clavien-Dindo scale. Staged surgical treatment including one or more debridement procedures before the final thoracoplasty was performed in 62 (62%) out of 100 patients. Aseptic sternal instability was observed in 38 patients. RESULTS: Follow-up period ranged from 3 weeks to 35 months after the final thoracoplasty. Complicated postoperative period occurred in 15 (15%) out of 100 patients (95% CI 9.3-23.3). One patient died in 9 days after surgery from acute heart failure. Complications without need for redo surgery, postoperative wound suppuration and seroma were noted in 3 patients. Redo surgery was required in 11 patients due to postoperative wound suppuration, eventration after thoracoomentoplasty, intermuscular hematoma and delayed divergence of major pectoral muscles. Removal of mesh implant was performed in 1 out of 100 patient (95% CI 0.2-5.5) in 7 days after surgery due to suppuration. There was no recurrent sternal instability within 30 days. CONCLUSION: Anterior chest wall reconstruction using titanium mesh implant is an effective and safe procedure in patients with postoperative sternal instability following postoperative sternomediastinitis.

[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.

[Fast-track rehabilitation after anatomical lung resection: prospective single-center non-randomized trial]. / Prospektivnoe odnotsentrovoe nerandomizirovannoe issledovanie uskorennoi reabilitatsii patsientov posle anatomicheskikh rezektsii legkikh.

AIM: To present the results of fast track rehabilitation after anatomical lung resection. MATERIAL AND METHODS: Single-center prospective non-randomized trial has included patients for the period December 2014 - December 2016. Conventional protocol was applied in 124 patients, 58 patients after atypical lung resections or pneumonectomy were excluded from the study. Thus, there were 66 patients aged 61 (51; 67) years. Men/women ratio was 37:29. Lobectomy (n=55) and segmentectomy (n=11) were performed for lung cancer, metastatic injury and various inflammatory diseases in 53 (80.3%), 8 (12.1%) and 5 (7.6 %) cases, respectively. ASA risk score was II (16), III (46), IV (4). Video-assisted/open procedures ratio was 42 (63.6%) / 24 (36.4%). RESULTS: 30-day postoperative morbidity was 7.6% (5 out of 66 patients, 95% CI 3.3- 16.5). Pleural drainage tube was removed within the 1st postoperative day in 49 (74.2%) out of 66 patients. Prolonged insufficient aerostasis was observed in 3 patients followed by effective conservative treatment. Overall mortality was 3% (n=2, 95% CI 0.8- 10.4) due to pulmonary embolism and sudden cardiac death. Median of postoperative hospital-stay was 7 (6; 9) days without significant differences between groups of lobectomy and segmentectomy (p>0.05). CONCLUSION: Fast track rehabilitation protocol in thoracic surgery is safe and effective. Further studies are needed to justify early rehabilitation in high risk patients.

[Laparoscopic-assisted harvesting of omental flap in chest wall reconstruction for deep sternal wound infection]. / Laparoskopicheski-assistirovannaia torakoomentoplastika v rekonstruktsii obshirnykh defektov perednei grudnoi stenki.

AIM: To present an experience of laparoscopic-assisted harvesting of omental flap in chest wall reconstruction for deep sternal wound infection. MATERIAL AND METHODS: It was made a prospective analysis of 14 patients aged 39-85 years after laparoscopic-assisted harvesting of omental flap in chest wall reconstruction for the period December 2014 - November 2016. Men/women ratio was 10/4. All patients had deep sternal wound infection grade IV (Oakley-Wright classification). RESULTS: Postoperative complications were observed in 2 (14.3%) of 14 (95% CI: 4.0-39.9%) cases that did not require re-operation. There were no 30-day postoperative mortality and significant complications as acute intestinal obstruction, postoperative ventral herniation and transplant rejection. Mean postoperative hospital-stay was 10.5 (9; 13) days. CONCLUSION: Laparoscopic-assisted harvesting of omental flap is safe method for chest wall reconstruction in patients with severe sternal wound infection associated with soft tissue deficiency and high risk of local complications (bleeding, etc.). Laparoscopy significantly reduces incidence of postoperative complications after omental flap transposition and is feasible in majority of patients.

[Differential approach for chest wall reconstruction for pectus excavatum in adults]. / Vybor metoda korrektsii voronkoobraznoi deformatsii grudnoi kletki u patsientov starshego vozrasta.

AIM: To perform the prospective non-randomized single-center trial of pectus excavatum correction in adults. MATERIAL AND METHODS: For the period March 2012 - March 2016 64 patients aged 18-44 years were treated. Median age was 23 years. Male/female ratio was 41/23. All patients were included into standard survey protocol: chest MDCT, MRI of thoracic spine, pulmonary function test, echocardiography. Quality of life and complications rate after the Nuss procedure (n=50, 78.1%, group 1) and radical thoracoplasty using nikelid-titanium bar (n=14, group 2) were evaluated. RESULTS: There was earlier recovery in the 1st group: 3 (2; 4) and 6 (5; 7) days after minimally invasive and radical thoracoplasty, respectively. Postoperative Dindo-Clavien I-IIIa complications developed in 46 (71.8%) patients. Most of them did not require additional procedures. CONCLUSION: Nuss procedure is safe method and can be performed with good results in adults.
