Project description:The chest wall functions as a protective cage around the vital organs of the body, and significant disruption of its structure can have dire respiratory and circulatory consequences. The past several decades have seen a marked improvement in the management and reconstruction of complex chest wall defects. Widespread acceptance of muscle and musculocutaneous flaps such as the latissimus dorsi, pectoralis major, serratus anterior, and rectus abdominis has led to a sharp decrease in infections and mortality. Successful reconstructions are dependent upon a detailed knowledge of the functional anatomy and blood supply of the chest and the underlying pathophysiology of a particular disease process. This article will provide an overview of key principles and evidence-based approaches to chest wall reconstruction.

Project description:Chest wall tumors are a relatively uncommon disease in clinical practice. Most of the published studies about chest wall tumors are usually single-center retrospective studies, involving few patients. Therefore, evidences regarding clinical conclusions about chest wall tumors are lacking, and some controversial issues have still to be agreed upon. In January 2019, 73 experts in thoracic surgery, plastic surgery, science, and engineering jointly released the Chinese Expert Consensus on Chest Wall Tumor Resection and Chest Wall Reconstruction (2018 edition). After that, numerous experts put forward new perspectives on some academic issues in this version of the consensus, pointing out the necessity to further discuss the points of contention. Thus, we conducted a survey through the administration of a questionnaire among 85 experts in the world. Consensus has been reached on some major points as follows. (I) Wide excision should be performed for desmoid tumor (DT) of chest wall. After excluding the distant metastasis by multi-disciplinary team, solitary sternal plasmacytoma can be treated with extensive resection and adjuvant radiotherapy. (II) Wide excision with above 2 cm margin distance should be attempted to obtain R0 resection margin for chest wall tumor unless the tumor involves vital organs or structures, including the great vessels, heart, trachea, joints, and spine. (III) For patients with chest wall tumors undergoing unplanned excision (UE) for the first time, it is necessary to carry out wide excision as soon as possible within 1-3 months following the previous surgery. (IV) Current Tumor Node Metastasis staging criteria (American Joint Committee on Cancer) of bone tumor and soft tissue sarcoma are not suitable for chest wall sarcomas. (V) It is necessary to use rigid implants for chest wall reconstruction once the maximum diameter of the chest wall defect exceeds 5 cm in adults and adolescents. (VI) For non-small cell lung cancer (NSCLC) invading the chest wall, wide excision with neoadjuvant and/or adjuvant therapy are recommended for patients with stage T3-4N0-1M0. As clear guidelines are lacking, these consensus statements on controversial issues on chest wall tumors and resection could possibly serve as further guidance in clinical practice during the upcoming years.

Project description:Chondrosarcomas are common bone carcinomas; however, they are uncommon in the sternum, and giant sternal tumors have rarely been reported in advanced-age patients. This study aimed to describe the clinical presentation, method of preoperative planning and surgery, and perioperative management of a giant sternal chondrosarcoma in an advanced-age patient. We describe the case of an 80-year-old woman who presented with a rare giant sternal chondrosarcoma. The patient's symptoms included significant painful swelling and limited activity. The mass was firm and fixed, and the boundary was unclear. We first performed a simulated surgery on a three-dimensional (3D) model using the mimics system for preoperative planning. An extensive resection of the tumor was then performed. Due to the financial status of the patient, the huge chest wall defect was reconstructed with simple ordinary metal locking bone plates and polyester surgical mesh, and good results were achieved. The patient was discharged without any complications 12 days after surgery. The postoperative pathological examination confirmed the diagnosis of primary grade I-II chondrosarcoma. At the 12-month follow-up examination, the patient was completely rehabilitated, and there was no evidence of recurrence. Giant, low-grade sternal chondrosarcoma is an extremely rare disease in elderly women. 3D modeling and simulated surgery are effective approaches for the preoperative planning of surgery. Postoperative ventilators, antibiotics, and nutritional support are also necessary. Using our reconstructive techniques, chest wall reconstruction with polyester patches and orthopedic steel plates could be a safe, reliable and affordable surgery procedure. It may be an appropriate option for similar cases.

Project description:The omentum, external oblique musculocutaneous, and thoracoepigastric flaps are uncommonly used for chest wall reconstruction. Nevertheless, awareness and knowledge of these flaps is essential for reconstructive surgeons because they fill specific niche indications or serve as lifeboats when workhorse flaps are unavailable. The current report describes the anatomic basis, technical aspects of flap elevation, and indications for these unusual flaps.

Project description:Three-dimensional printed (3DP) implant offers a valid option with perfect anatomic fitting in individual and skeletal reconstruction of the chest wall. Herein, we present the case of a patient with a large chest wall tumor, where an extensive chest wall defect was repaired using 3DP polyether-ether-ketone (PEEK) implants. Surgical treatment planning was performed according to the computed tomography (CT) images in DICOM format. A 3DP implant was then design and fabricated. A wide excision of the chest wall tumor was performed, including the entire sternum, 2-6 costal cartilage and ribs, and parietal pleura. Furthermore, a skeletal reconstruction was carried out using a 3DP PEEK implant. The patient recovered well without surgical complications or tumor recurrence in the following year. In general, 3DP PEEK implant is an appropriate alternative for chest wall reconstruction. KEY POINTS: SIGNIFICANT FINDINGS OF THE STUDY: Skeletal reconstruction after wide excision of the chest wall remains a challenging problem for clinicians. WHAT THIS STUDY ADDS: 3DP PEEK implant is an appropriate alternative for chest wall reconstruction.

Project description:BackgroundImplant-based reconstruction represents the most common form of breast reconstruction after mastectomy. Although the complication rate has lowered owing to the current advances, various implant-related complications are still a problem. There have been few reports discussing chest wall deformation following implant insertion. The aim of this study was to quantify chest wall depression (CWD) after breast implant insertion and identify possible risk factors.MethodsPatients who underwent unilateral direct-to-implant reconstruction were included in the study. We measured the pre- and postoperative antero-posterior length of the chest wall and used a CWD ratio to measure the change in length. Multivariate analysis was performed with factors with P values of <0.2 in univariate analyses to identify factors associated with CWD.ResultsA total of 57 patients were included in this study. The pre- and postoperative difference of antero-posterior length was statistically significant using a paired t-test. Average depth of CWD was 4.16 mm (range, -2.16 to 13.82 mm). In multivariate analysis, capsular contracture and age were the independent prognostic factors correlated with CWD.ConclusionsThis study showed the possibility of CWD following implant insertion. Surgeons and specialists should be aware of the possibility and risk factors of CWD following implant insertion to better inform patients.

Project description:Defect reconstruction after radical oncologic resection of malignant chest wall tumors requires adequate soft tissue reconstruction with function, stability, integrity, and an aesthetically acceptable result of the chest wall. The purpose of this article is to describe possible reconstructive microsurgical pathways after full-thickness oncologic resections of the chest wall. Several reliable free flaps are described, and morbidity and mortality rates of patients are discussed.

Project description:A 5-year-old girl was referred to our department for a mass of sternum that was previously biopsied and diagnosed as hemangioma. Chest X-ray and CT scan confirmed a large sternal mass. We resected the sternum completely and reconstructed a large anterior chest wall defect by a cryopreserved sternal allograft. In the follow-up of the patient, there was no instability of the chest wall and acceptable cosmetic results.
