[Chest wall reconstruction with a non-rigid synthetic rib prosthesis: a multicenter study]. / Rekonstruktsiya grudnoi stenki nerigidnym sinteticheskim protezom rebra: mul'titsentrovoe issledovanie.

Chest wall resection is performed for a variety of diseases, for primary rib and soft tissue tumors, metastatic lesions, or locally invasive growth of lung and mediastinal tumors being the most common indications. Following the resection phase, it is essential to determine the method of chest wall reconstruction that will restore the structural function, preserve pulmonary biomechanics, reduce the likelihood of residual pleural space, pulmonary hernia, and protect intrathoracic organs. The main objective of this study is to investigate the outcomes of chest wall resection with reconstruction using Codubix material. MATERIAL AND METHODS: This retrospective multicenter study included 22 patients who underwent chest wall tumor resection with subsequent Codubix rib endoprosthesis reconstruction from 2019 to 2023. Four medical institutions participated in the study: P.A. Herzen Moscow Cancer Research Institute, Sverdlovsk Regional Oncology Hospital, Morozov Children's City Clinical Hospital and Kaluga Regional Oncology Hospital. Inclusion criteria were the presence of chest wall tumors, both primary and secondary, removal of more than 2 ribs, resection of the rib arch and the sternum. RESULTS: The median age was 60 years (48-66), 11 (50%) patients were females and 11 (50%) males. Operations for chest wall sarcoma, metastatic lesions, and lung cancer were performed in 9 (40.9%), 4 (18.2%), and 3 (13.6%) patients, respectively. The median number of removed ribs was 3 (2-4), with a maximum of 7. Sternotomy was performed in 9 (40.9%) patients, and subtotal resection of the body or handle of the sternum was carried out in 77.7%. Combined resections were performed in 14 (63.6%) patients. Radical tumor removal (R0) was achieved in 21 (95.5%) patients. Complications were observed in 9 (40.9%) patients, with intermuscular seroma being the most common in three (33.3%), followed by hydrothorax in 2 (22.2%), bilateral pneumonia, acute respiratory failure, and postoperative delirium in 1 (11.1%) patient each. One patient had the Codubix plate removed due to postoperative wound infection. The median overall and recurrence-free survival was not reached, and the 1-year recurrence-free survival was 63.9%, with an overall survival of 86.8%. CONCLUSION: Reconstruction with Codubix material allows for satisfactory functional and cosmetic results, characterized by a low complication rate and good adaptive properties.

[Chest wall repair after extensive resections]. / Rezul'taty vosstanovleniya karkasa grudnoi stenki posle obshirnykh rezektsii.

OBJECTIVE: To analyze the outcomes after different methods of post-resection chest wall defect reconstruction. MATERIAL AND METHODS: The study included 41 patients aged 22-73 years who underwent chest wall repair with local tissues and synthetic materials. Twelve (29.3±7.1%) patients had sarcoma, 9 (21.9±5.9%) - non-small cell lung cancer (NSCLC) with invasion of the chest, 9 (21.9±5.9%) - metastatic lesions, 8 (19.5±6.2%) - benign tumors, 2 (4.8±3.4%) - breast cancer with invasion of the chest wall, 1 (2.4±2.4%) - desmoid tumor. Seven patients were diagnosed with T3N0M0, 1 - T3N2M0, 1 - T2N0M1b (oss). Among patients with NSCLC with invasion into the chest wall, squamous cell cancer was verified in 4 (44.4±16.6%) patients, adenocarcinoma - in 4 (44.4±16.6%), neuroendocrine tumor - in 1 (11.2±10.5%) patient. Stages of surgeries are presented. RESULTS: We analyzed treatment outcomes in 41 patients. Five (12.2%) patients had seroma, hemothorax, thoracopleural fistula, subcutaneous emphysema and fatal asystole. There were no postoperative complications associated with paradoxical breathing. CONCLUSION: Accurate morphological verification prior to treatment is valuable to determine the stages of combined treatment of chest wall tumors. Chest wall defect closure with own tissues and synthetic materials is necessary after extensive resections. A multidisciplinary approach involving thoracic and plastic surgeons is needed.

[Post-traumatic thoracic splenosis]. / Klinicheskii sluchai posttravmaticheskogo grudnogo splenoza.

Splenosis is a rare disease and defined as spleen tissue autotransplantation following spleen rupture and subsequent splenectomy in most cases. The authors report ectopic splenic tissue in pleural cavity diagnosed in 31 years after blunt thoracoabdominal trauma.
