RESUMO

This patient presented with a stage IIIB advanced lung cancer with chest wall invasion. She was treated with neoadjuvant chemoradiation therapy and had an excellent treatment response. The management of T3N2 disease is controversial, but given her treatment response and age, she was discussed by the multidisciplinary tumour board and referred for surgical evaluation. She was offered a robotic en bloc lobectomy and chest wall dissection.

RESUMO

BACKGROUND: Intrathoracic neurogenic tumors arise from sympathetic nerve trunks and intercostal nerves; more than 90% are benign. Schwannomas are the most common histological variety, but fatalities due to giant schwannomas are rare. CASE PRESENTATION: We report a case of a 65-year-old woman who presented with chest pain and cough. Computed tomography (CT) revealed a large left chest wall mass of 130-mm in size, and the patient was referred to our department. Tumor biopsy was performed under local anesthesia, and a diagnosis of schwannoma was made. Ten years previously, a 30-mm tumor had been noted in the left third intercostal space by a previous doctor, but follow-up had been interrupted owing to depressive disorder. Although we planned to perform intercostal artery embolization followed by chest wall tumor resection, the patient did not consent to surgery due to uncontrolled depression. After four months, she developed respiratory failure caused by compression due to an enlarged tumor and died. Autopsy also revealed a benign schwannoma with no malignant findings. CONCLUSIONS: Although schwannomas are benign tumors, there are some very rare cases in which they can become huge and life-threatening. Therefore, a benign tumor should not be neglected, and if surgery is not possible at the time of diagnosis, a regular follow up is necessary, in order not to miss the right timing for surgery.

RESUMO

STUDY DESIGN: Retrospective review. OBJECTIVE: To evaluate the effectiveness of halo-pelvic traction and thoracoplasty for pulmonary artery pressure (PAP) and cardiopulmonary function in patients with severe spinal deformity. SUMMARY OF BACKGROUND DATA: The effect of severe spinal deformity on pulmonary arterial hypertension, cardiac structure, and function has received little attention before. PATIENTS AND METHODS: A total of 21 patients with severe spinal deformity were included in our study; all patients were examined by echocardiography and pulmonary function test before and after treatment. The correlations between PAP and pulmonary function were examined using Pearson correlation analysis. RESULTS: The PAP decreased from 58.67 ± 20.24 to 39.00 ± 12.51 mm Hg, and the PAP of 42.86% of the patients returned to normal after treatment. Right cardiac enlargement, left ventricular diastolic function, and pulmonary function were improved at the same time. The ratio of left ventricular to right ventricular diameter returned to normal. Moderate correlations (correlation coefficient: -0.513 to -0.559) between PAP and forced vital capacity and forced expiratory volume in the first second were identified. CONCLUSIONS: Pulmonary arterial hypertension, ventricular diastolic function, and pulmonary function were improved after halo-pelvic traction and thoracoplasty. A moderate negative correlation was identified between PAP and pulmonary function: the more pulmonary function improved, the more PAP decreased.

RESUMO

Introducción: La toracoplastia percutánea videoasistida implica un acceso quirúrgico complejo y con riesgo de dañar estructuras vitales durante el procedimiento. Históricamente se han aplicado distintos sistemas de tracción y elevación esternal durante la intervención con el fin de minimizar el riesgo asociado al paso del instrumental entre el esternón y el pericardio. Métodos: Se presenta mediante una descripción ilustrada un nuevo sistema de tracción esternal. Se extrajeron los datos clínicos y sociodemográficos de los 36 pacientes intervenidos en nuestro centro de Pectus Excavatum entre julio 2017 y agosto 2021. Todos los pacientes fueron intervenidos por el mismo cirujano. Se clasificó a los pacientes en función de si se había empleado el sistema de tracción esternal (TE) o no (ST). La asignación a uno u otro grupo de intervención se hizo siguiendo un criterio cronológico, sin aplicar el índice de Haller u otro índice. El análisis estadístico de los datos recogidos se realizó con STATA, versión 15.0 (StataCorp). Resultados: La distribución de las variables sociodemográficas muestra que no había diferencias significativas entre los grupos. En 25 de los pacientes se empleó el sistema TE y en 11 no se utilizó ningún ST. El Índice de Haller fue de 4,19±0,7 para el grupo TE y de 3,79±0,3 para el ST. El tiempo quirúrgico medio en minutos fue 88,13±18,1 para el grupo TE y 97,73±46,2 para el grupo ST (p=0,87). La media de días de ingreso fue 7,67±0,8 y 7,73±1,3 para el grupo TE y ST respectivamente. La media de días de PCA intravenosa fue 6,08±0,7 para el grupo TE y 5,89±1,5 para el ST. La media de días de PCA epidural fue 3,79±0,5 y de 3,36±0,5 para el grupo TE y ST respectivamente (p=0,01). Todos los pacientes presentaron una evolución postoperatoria favorable. Ninguno de los pacientes presentó molestias a nivel de las heridas esternales durante el ingreso en hospitalización. La evolución cosmética fue favorable en todos los pacientes. (AU)


Introduction: Video-assisted percutaneous thoracoplasty involves a complex surgical access with risk of damaging vital structures during the procedure. Historically, different traction and sternal elevation systems have been applied during the intervention to minimize the risk associated with the passage of the instruments between the sternum and the pericardium. Methods: A new sternal traction system is presented by means of an illustrated description. Clinical and sociodemographic data were extracted from the 36 patients operated in our center for Pectus Excavatum between July 2017 and August 2021. The Haller index was not applied as a criterion to determine the use or not of the sternal traction system. Patients were classified according to whether the sternal traction system (TE) or not (ST) had been employed. Statistical analysis of the data collected was performed with STATA, version 15.0 (StataCorp). Results: Both groups were comparable. In 25 of the patients the described traction system was used, and in 11 no traction system was used. Haller's index was 4.19±0.7 for the TE group and 3.79±0.3 for the ST group. All patients were operated on by the same surgeon. The mean operative time in minutes was 97.73±46.2 for the ST group and 88.13±18.1 for the TE group (P=.87). The mean total days of admission was 7.67±0.82 (TE) and 7.73±1.35 (ST). Mean days of intravenous PCA was 6.08±0.72 (TE) and 5.89±1.45 (ST). The mean number of epidural PCA days was 3.79±0.5 (TE) and 3.36±0.5 (ST) (P=.01). All patients presented a favorable postoperative evolution. None of the patients presented discomfort at the level of the sternal wounds during hospitalization. Cosmetic evolution was favorable in all patients. (AU)

RESUMO

PURPOSE: Malignant chest wall tumors are rare in pediatrics. They require multimodal oncological treatment and local surgical control. Resections are extensive; therefore, thoracoplasty should be planned to protect intrathoracic organs, prevent herniation, future deformities, preserve ventilatory dynamics, and enable radiotherapy. METHODS: We present a case series of children with malignant chest wall tumors and our surgical experience with thoracoplasty using absorbable rib substitutes (BioBridge®), after local surgical control. BioBridge® is a copolymer made of a polylactide acid blend (70% L-lactic acid y 30% DL-lactide). RESULTS: In 2 years, we had three patients with malignant chest wall tumors. Resection margins were negative, without recurrence at follow-up. We achieved good cosmetic and functional results, and no postoperative complications. CONCLUSION: Alternative reconstruction techniques such as absorbable rib substitutes provide protection, guarantee a flexible chest wall, and do not interfere with adjuvant radiotherapy. Currently, there are no management protocols in thoracoplasty. This option represents an excellent alternative for patients with chest wall tumors. Knowledge of different approaches and reconstructive principles is essential to offer children the best onco-surgical option.

RESUMO

BACKGROUND/PURPOSE: Quantification of the severity of pectus excavatum deformities is currently performed using the Haller index (HI) and the Correction index (CI), amongst others. However, most indexes characterize the severity at the point of maximum excavation. We present a new index, the Titanic index (TI), aimed at the appraisal of the cephalocaudal extent of the excavation and its potential clinical use. MATERIALS AND METHODS: Retrospective analysis of a cohort of patients who underwent a minimally invasive repair of pectus excavatum (MIRPE) between July 2020 and April 2022 at a single center. We defined TI as the percentage of the sternum that lied behind the anterior costal line observed in the CT. Demographics, HI, CI, and TI calculated based on computed tomography images (CT) were analyzed. Also, we compared the severity indexes of two groups of patients divided by the number of implants introduced per patient (group A: two implants, and group B: more than two). RESULTS: Seventy-eight patients (92% male) were included, with a mean age of 17.2 ± 4.8 years. The mean TI was 37%. Albeit weak, we identified significant correlations between the TI and the HI and, more closely, to the CI. Two implants were introduced in 37 (47%) patients, and more than two in 41 (53%) patients. Compared to patients with two implants, the group of patients who received more than two implants were older and showed worse thoracic indexes. Using receiver operating characteristic curve analysis, we identified the TI as a better predictor of the need for more than two implants than HI and CI. In this regard, a TI larger than 66.5% had a sensitivity of 93% and a specificity of 92%. CONCLUSION: We propose a novel index for the categorization of the severity of pectus excavatum. This index might be useful in planning the number of implants required for complete thoracic remodeling during MIRPE. LEVEL OF EVIDENCE: Level III. TYPE OF STUDY: Retrospective Comparative Study.

RESUMO

PURPOSE: To provide better evidence of the efficacy and safety of preoperative halo-pelvic traction on the improvements of deformity and pulmonary functions in patients with severe scoliosis. METHODS: Electronic database searches were conducted including the Cochrane Library, PubMed, Web of Science and Embase. All studies of halo-pelvic traction for the management of severe spinal deformity were included. We referred to a list of four criteria developed by the Agency for Healthcare Research and Quality (AHRQ) to assess the quality of included studies. The meta-analysis was performed using RevMan 5.4 software. RESULTS: Based on the study selection criteria, a total of eight articles consisting of a total of 210 patients were included. Statistically significant differences were found in coronal Cobb angle (P < 0.001), sagittal Cobb angle (P < 0.001) and height (P < 0.001) between pre- and post-traction. Sensitivity analysis was conducted, and there were substantial changes in heterogeneity with preoperative thoracoplasty subgroup in coronal Cobb angle (P < 0.001). Three trials including 74 subjects reported FVC and FEV1 predicted value between pre- and post-traction. There were statistically significant differences in FVC, FVC%, FEV1 and FEV1% (P < 0.001). The complication rate was 6.6-26.7%, and symptoms disappeared after reasonable traction strategy and intensive care. CONCLUSIONS: Preoperative halo-pelvic traction achieved significant improvements in spinal deformity and pulmonary functions, with minor and curable complications. Thus, it is an effective and safe solution before surgery and may be the optimal choice for severe scoliosis. In light of the heterogeneity and limitations, future researches are needed to better determine the long-term efficacy on comprehensive assessment and to explore the appropriate traction system.

RESUMO

BACKGROUND: Chest wall reconstruction can be a challenge. The perfect material does not exist to restore chest wall stability. Synthetic materials have been the mainstay for reconstruction. Biological material use has increased. Recently, we initiated the use of a biosynthetic material for chest wall reconstruction that is composed of ovine-derived extracellular tissue matrix and monofilament polypropylene suture. METHODS: We respectively reviewed all patients who underwent chest wall reconstruction with a biosynthetic material from January 2020 to June 2021. RESULTS: Twenty-five patients underwent chest wall reconstruction. Median age was 35 years (range, 18 to 68); 64% were men. Indication for reconstruction was tumor resection in 10, chest wall defect after pectus repair in 7, radiation necrosis in 5, chest wall infection in 2, and lung herniation in 1. Infection was present in 28%. Median chest wall defect was 7 × 10 cm (range, 3.5 to 22.5 cm). Bioabsorbable bars were used in combination with the biosynthetic material patch in 15 patients (60%) and biosynthetic material alone in 10; 5 patients underwent myocutaneous advancement flaps. There were no operative deaths. Postoperative complications occurred in 6 patients (24%). Median hospital stay was 5 days (range, 3 to 14). Late complications occurred in 4 patients (16%). No patient had paradoxical motion, chest wall instability, or required biosynthetic material removal at a median follow-up of 12 months (range, 1 to 18). CONCLUSIONS: This novel biosynthetic material combines the benefits of biologic material and polymer reinforcement to provide a more natural chest wall reconstruction compared with mesh products made of synthetic material alone. Early results are promising in this first series in the literature.

Statistical analysis of the data collected was performed with STATA, version 15.0 (StataCorp). RESULTS: Both groups were comparable. Haller's Index was 4.19 ± 0.7 for the sternal traction (TE) group and 3.79 ± 0.3 for the no sternal traction (ST) group. In 25 of the patients the described traction system was used, and in 11 no traction system was used. All patients were operated on by the same surgeon. The mean operative time in minutes was 97.73 ± 46.2 for the ST group and 88.13 ± 18.1 for the TE group (p = 0.87). The mean total days of admission was 7.67 ± 0.82 (TE) and 7.73 ± 1.35 (ST). Mean days of intravenous PCA was 6.08 ± 0.72 (TE) and 5.89 ± 1.45 (ST). The mean number of epidural PCA days was 3.79 ± 0.5 (TE) and 3.36 ± 0.5 (ST) (p = 0.01). All patients presented a favorable postoperative evolution. None of the patients presented discomfort at the level of the sternal wounds during hospitalization. Cosmetic evolution was favorable in all patients. CONCLUSIONS: The sternal traction system presented provides safety when performing retrosternal dissection and placement of the thoracoplasty bar, leading to a decrease in surgical time in cases with a Haller Index higher than 3.5. There have been no complications associated with its use, nor has there been an increase in the number of days of hospitalization or analgesic requirements. There are no aesthetic sequelae for the patients.

RESUMO

OBJECTIVE: To present the results of reconstruction of post-resection chest wall defects with nickel-titanium (TiNi) implants in patients with invasive NSCLC and to analyze the features of perioperative management. MATERIAL AND METHODS: We enrolled 9 patients with NSCLC involving the ribs after lobectomy or pneumonectomy with chest wall reconstruction. Defects were closed used TiNi mesh and rib prostheses. We selected the shape and dimensions of artificial ribs individually before surgery according to CT data and 3D models of reinforcing elements. RESULTS: There were male smokers aged 64.6±4.6 years among patients (range 58-73). T3N0M0 was diagnosed in 6 patients, T3N1M0 - 2, T3N2M0 - 1. Squamous cell carcinoma was verified in 4 (44.4%) patients, adenocarcinoma - in 5 (55.6%) patients. All patients had comorbidities. Mean Charlson's comorbidity index was 6.56±4.6. Dimension of chest wall defect varied from 78 to 100 cm2. Postoperative period was uneventful without signs of respiratory failure. There were no lethal outcomes. Complications occurred in 33.3% of patients (prolonged air discharge through the drains, pleuritis and atrial fibrillation). CONCLUSION: Surgical treatment of NSCLC spreading to the chest wall is a complex task requiring further improvement. Bioadaptive TiNi implants are a promising reinforcing material that allows successful reconstruction of post-resection chest wall defects with good anatomical, functional and cosmetic results. «Sandwich¼ technology is advisable for extensive defects. This approach includes 2 layers of knitted mesh and rib prostheses between these layers.

RESUMO

OBJECTIVES: The reconstruction of the chest wall defect after tumour resection presents a challenge. Titanium rib plates were presented as a reconstruction option due to its biocompatibility, flexibility and pliability. The aim of this study was to evaluate the outcome of single-centre cohort treated with chest wall reconstruction after tumour resections, with a focus on the titanium rib plates reconstruction. METHODS: We retrospectively reviewed the data of 26 patients who underwent wide resection for malignancies of the chest wall, where reconstruction was performed using polypropylene mesh, porcine dermal collagen mesh with or without titanium rib plates, operated on between 2012 and 2019. Events being associated with the surgery requiring revision were rated as complications. RESULTS: Most of the patients had primary tumours (n = 19; 73%). A mean of 3.7 ribs (range: 1-7) was resected. Reconstruction was performed with titanium rib plates (13 patients, 50%), of these 11 were performed with additional mesh grafts. The remaining 13 patients (50%) underwent reconstruction with mesh grafts only. Fourteen patients (54%) developed a complication requiring surgical revision, after a median of 5.5 months. The most common complication was wound healing deficit (n = 4), plate fracture (n = 2), mesh rupture (n = 2), infection (n = 2) and local recurrence (n = 2). The only factor being associated with the development of complications was the usage of a plate (P = 0.015), irrespective of defect size (P = 0.29). CONCLUSIONS: The high complication rate is found when using titanium plates for chest wall reconstruction after tumour resection. A high caution is recommended in choosing the chest wall reconstruction method.

RESUMO

PURPOSE: Thoracoplasty is a procedure which involves rib resection from the costovertebral junction to the apex of the rib hump deformity to address the cosmetic concerns of patients of scoliosis. There is conflicting literature on its effect on pulmonary function. The present meta-analysis was conducted to review and analyze the available literature and ascertain the effect of thoracoplasty on pulmonary function. METHODS: Search was conducted according to PRISMA guidelines on three databases. After analysis of all the search results by title, abstracts and full texts-10 studies were identified for inclusion in the review. We included studies which had analyzed preoperative and postoperative pulmonary function tests (PFTs) after thoracoplasty. Pooled estimates were calculated for pulmonary function, and effect of other factors was analyzed by subgroup analysis and meta-regression. RESULTS: The included studies were published between 1998 and 2019. A total of 385 patients were included in these studies, with a mean age of 15.01 years, with a female preponderance. Apprehension over appearance of rib hump was the most common indication for thoracoplasty. Percent-predicted forced vital capacity (FVC) and forced expiratory volume in 1 s (FEV-1) were significantly decreased on follow-up. Anterior approach to corrective surgery and lower age were found to be associated with worse pulmonary function. Preoperative Cobb's angle was found to have significant impact on decrease in FEV-1 only, but not on other PFT parameters. CONCLUSION: Overall decrease in pulmonary function after thoracoplasty necessitates the need of adequate preoperative pulmonary function to mitigate its effect on patient well-being. Use of a posterior approach for corrective surgery when thoracoplasty is planned might lead to better outcomes. More research is needed to study effect of preoperative Cobb's angle on pulmonary function.

RESUMO

PURPOSE: Chest wall resections for lung cancer treatment remain difficult to plan using standard 2-dimensional computed tomography. Although virtual reality headsets have been used in many medical contexts, they have not been used in chest wall resection planning. DESCRIPTION: We compared preoperative planning of a chest wall surgical resection for lung cancer treatment between senior and resident surgeons who used an immersive virtual reality device and a 2-dimensional computed tomography. EVALUATION: Chest wall resection planning was more accurate when surgeons used virtual reality vs computed tomography analysis (28.6% vs 18.3%, P = .018), and this was particularly true in the resident surgeon group (27.4% vs 8.3%, P = .0025). Predictions regarding the need for chest wall substitutes were also more accurate when they were made using virtual reality vs computed tomography analysis in all groups (96% vs 68.5%, P < .0001). Other studied parameters were not affected by the use of the virtual reality tool. CONCLUSIONS: Virtual reality may offer enhanced accuracy for chest wall resection and reconstruction planning for lung cancer treatment.

RESUMO

Owing to the advent of effective drugs for tuberculosis in the mid-twentieth century, few cases require surgery for active tuberculosis in the present day in areas where effective drugs are available. However, surgical techniques developed to combat tuberculosis in the predrug era are still useful to manage the challenging chest pathology of our time surgically, such as destroyed lung or postresectional empyema. Thoracoplasty and open window thoracostomy are representative procedures and discussed in detail in this review.

RESUMO

PURPOSE: To perform a study to investigate the influence of posterior scoliosis surgery and thoracoplasty on pulmonary function. METHODS: This was a retrospective observational study of 37 patients with AIS who underwent posterior instrumented surgical correction with thoracoplasty. There was a minimum of 2 years follow-up. Clinical outcomes were measured using the SRS-22 questionnaires. Radiological outcomes were evaluated using standing posteroanterior and lateral radiographs. All patients had pulmonary function tests to evaluate pulmonary volume and flow (forced expiratory volume in the first second (FEV1) and forced vital capacity (FVC)) both before surgery and at the final follow-up. RESULTS: There were three males and 34 females. The mean age of patients was 14.6 years (range 11-21 years). The mean length of follow was 58 months (range 24-124 months). The average main thoracic Cobb angle in the coronal plane was corrected from 50.0° ± 12.4° preoperatively to 16.6° ± 6.3° postoperatively. The average thoracolumbar Cobb angle in the coronal plane was corrected from 28.2° ± 10.6° preoperatively to 10.1° ± 7.2°. The average thoracic kyphosis angle was corrected from 17.4° ± 11.0° preoperatively to 21.8° ± 10.5°. In terms of the Quality of life Outcomes (QoL), there was a significant increase (p < 0.001) in the mean SRS 22 scores from 3.8 preoperatively to 4.3 postoperatively. A statistically significant increase in the absolute forced expiratory volume in one second (FEV1) from pre-operative values with a p value < 0.001 was seen. There was a statistically significant increase in percentage predicted forced expiratory volume in one second from preoperative values with a p value of 0.008. There was also a statistically significant increase in the absolute forced vital capacity (FVC) from preoperative values with a p value < 0.001. The average percentage predicted forced vital capacity did increase on final follow-up from before surgery, but the increase was not statistically significant. CONCLUSIONS: We have demonstrated that pulmonary function post-thoracoplasty not only reaches pre-operative levels, but significantly surpasses it with regards to the majority of the pulmonary parameters measured in this study.

RESUMO

Pectus excavatum is the most common congenital chest malformation characterized by symmetrical or asymmetric depression of the chest with deformation of the sternocostal complex. Pectus excavatum is often associated with other dysplastic diseases of connective tissue. Ravitch thoracoplasty and Nuss minimally invasive correction are the most common today. The authors report surgical correction of PE in a 50-years-old male who underwent Ravitch modified thoracoplasty with implantation of shape memory plate. Long-term treatment outcomes and technical properties of the plate after removing are analyzed.
