Abstract： Objective To summarize the application experience of Gore-Tex patch in clinical chest wall reconstruction. Methods A retrospective analysis was performed in 33 patients who underwent chest wall reconstruction using Gore-Tex patch from January 2001 to December 2010 in Shanghai Changhai Hospital, Second Military Medical University. There were 19 men and 14 women, ranging in age from 20 to 73 years with a median age of 45.7 years. The surgical strategies included choosing different incisions according to tumor location and size, and preserving normal chest wall soft tissue as much as possible during surgery. Gore-Tex patch was used to reconstruct the huge chest wall defect, and covered by transferred muscle flaps. Results All the 33 patients underwent surgical reconstruction successfully and there was no perioperative death. Complete tumor resection was performed in all the patients, including 25 patients with malignant tumor and 8 patients with benign tumor. The diameter of the resected tumors ranged from 8 to 20 cm. All the patients were followed up from 5 to 60 months, except that 3 patients （9.09%） were lost during follow-up. There was no rejection response, abnormal breathing and foreign body sensation during follow-up. The infection incidence was 3%（1/33）. Conclusion Gore-Tex patch is a safe and effective material for chest wall reconstruction due to its excellent biocompatibility. Appropriate selection of muscle flap for covering Gore-Tex patch can reduce postoperative complications.
OBJECTIVE: A rare huge desmoplastic fibroma on thoracic wall in 1 female case of 25 years old was resected, and the accompanying huge thoracic wall defect, ribs and soft tissues were repaired by tissue engineered bone and pedicled flap. The paper aims to explore the clinical results of early stage after operation. METHODS: Autogeneic bone marrow stromal cells (MSC) were obtained from bone marrow puncture of iliac bone and isolated and cultured according to the Houghton’s methods, MSC were directively induced and differentiated to osteoblasts. Allogeneic ribs were made to the bio-derived bone scaffold materials after treatment of decell, deantigen, decalcification and dry freezing. 5 x 10(6)/ml MSC were cocultured with the bio-derived bone for 6 days in vitro. After intact resection of tumor, the diaphragm flap was applied to repair pleural cavity, the three defect ribs were repaired by tissue engineered bone and the soft tissue defect was repaired by transfer of pedicled ipsilateral abdominal flaps. RESULTS: The patient recovered well with first intention. Followed up for 3 months, tissue engineered ribs were matured in vitro and the heart and pulmonary functions were improved markedly. CONCLUSION: The tissue engineered bone constructed by autogeneic MSC is advantageous in individual treatment.
Mediastinal and chest wall tumors contain various benign and malignant tumors. In order to further standardize the whole-course diagnosis and treatment of mediastinal and chest wall tumors, the consensus was formulated through discussion by the expert group. Based on the clinical diagnosis and treatment experience and various prospective and retrospective studies, the consensus was formed.
