It is reported in this paper that defect of chest wall of dogs were repaired by hetcrotransplantation of pig bone. The shape of original chest wail were achieved following operation. Histologic study showed that the grown between trabeculae with immersion that method is not only to have same function of other reparing materials,but there is no rejection.
Over a two year period, four patients of pectus carinatum received surgical correction at our hospital. All patients were followed up for 6 months to 1 year. The operative results were satisfactory but one required revision with additional resection of bilateral second cartilage for the persistent malformation. The clinical characteristics, operative techniques and indications for operative treatment were discussed.
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 To evaluate the application value of repairing the defects of the chest wall with the thoracico-abdominal skin flap and the muscle flap of the musculus rectus abdominis. Methods From January 2002 to June 2005, five patients with defects in the chest wall underwent the prothesis with the thoracico-abdominal skin flap and the muscle flap of the musculus rectus abdominis under general anesthesia. Focal cleaning was performed first; then, the skin flap was designed and taken (15 cm ×10 cm); and finally, the defects of the chest wall were repaired with the muscle flap of the musculus rectus abdominis. Results Of the 5patients, 4 had the flap healing by the first intention, and 1 had the delayed healing, with no complication. The skin flap had a good appearance, without edema orpigmentation. The X-ray examination showed that the shadow of the sternal sequestrum disappeared. There was no recurrence or complication during the follow-upfor 1-3 years (average, 18 mon). Conclusion The repairing of the defects in the chest wall with the thoracico-abdominal skin flap and the muscle flap of the musculus rectus abdominis is a simple and effective surgical treatment for defects of the chest wall around the sternum, and this kind of treatment is worth applying extensively in clinical practice.
Objective To investigate the current development status of chest wall surgery at all levels of hospitals in Sichuan Province, as well as to provide evidence for the promotion of chest wall surgery. Methods We conducted a questionnaire study to investigate chest wall surgery at all levels of hospitals in Sichuan Province and to collect suggestions for chest wall surgery development from thoracic surgeons attending the meeting of the Sichuan International Medical Exchange & Promotion Association from September 2021 to January 2022. Results A total of 128 questionnaires were issued, with 97 (75.8%) of them being valid. According to the survey results, hospitals with grade A secondary or higher in Sichuan Province performed chest wall surgery. Chest wall surgery accounted for 14.3% of thoracic surgery, with 70.4% being chest wall trauma surgeries, 11.6% being chest wall tumor surgeries, 10.5% being chest wall infection surgeries, and 7.5% being chest wall deformity surgeries. Chest wall surgery accounted for 9.3% of thoracic surgery in the grade A tertiary hospitals, primarily for chest wall trauma and tumor; 23.1% in grade B tertiary hospitals, primarily for chest wall trauma and tumor; and 50.7% in grade A secondary hospitals, primarily for chest wall trauma and infection. Totally 96.9% of hospitals supported the establishment of a subspecialty in chest wall surgery. Suggestions for advancing chest wall surgery included: enhancing communication and cooperation (e.g. holding academic conferences, training courses), the establishment of the chest wall surgery association or consortium, and the formulation of regulations and guidelines or consensus, etc. Conclusion Chest wall surgery has been performed at all levels of hospitals in Sichuan Province. The relevant guidelines can be made based on the related academic associations, thus boosting the development of chest wall surgery in the future.
Objective To investigate the surgical techniques and effectiveness for reconstruction of severe full-thickness chest wall defects. Methods Between January 2006 and December 2010, 14 patients with full-thickness chest wall defects were treated, including 12 cases caused by giant chest wall mal ignant tumor excision, 1 case by thermocompression injury, and 1 case by radiation necrosis. There were 8 males and 6 females with an average age of 42 years (range，23-65 years). The size of chest wall defects ranged from 8 cm × 5 cm to 26 cm × 14 cm. All patients compl icated by rib defect (1-5 ribs), and 3 cases by sternum defect. Thoracic skeleton reconstruction was performed with Vicryl mesh or polytetrafluroethylene mesh in 10 patients. Other 4 patients did not undergo thoracic skeleton reconstruction. The bilobed skin flaps, pectoral is major myocutaneous flap, latissimus dorsi myocutaneous flap, and rectus abdominis myocutaneous flap were util ized for repairing soft tissue defects. The size of the dissected flaps ranged from 10 cm × 7 cm to 25 cm × 13 cm. The donor sites were sutured directly or were repaired by free skin graft. Results Poor heal ing of incision occurred in 2 cases, which was cured after debridement, myocutaneous flap transfer, and skin graft. The other wounds healed by first intention. All patients were followed up 6-36 months (mean, 8 months). No tumor recurrence during follow-up, except 1 patient with osteosarcoma who died of l iver matastasis at 6 months after operation. Transient sl ight paradoxical respiration occurred in 1 patient who did not undergo thoracic skeleton reconstruction at 5 days after operation. Integrity of chest wall in other patients was restored without paradoxical respiration and dyspnea. Conclusion Depending on the cause, the size, and the location of defect, single or combination flaps could be used to repair soft tissue defect, and thoracic skeleton reconstruction should be performed when defect is severe by means of syntheticmaterials.
ObjectiveTo explore the surgical treatment of deep chest wall infection, improve the cure rate and reduce the recurrence rate.MethodsThe clinical data of 655 patients with deep chest wall infection treated in Yanda Hospital and Beijing Royal Integrative Medicine Hospital from June 2015 to June 2020 were retrospectively analyzed. There were 450 males and 205 females, aged 55.6±12.8 years. There were 8 patients with chest wall infection after tumor necrosis, 15 patients after radiotherapy and 632 patients after thoracotomy (612 patients after cardiovascular surgery and 20 patients after general thoracic surgery). Among them, 649 patients underwent debridement and reconstruction of chest wall defect with muscle flap.ResultsThe average operation time was 95±65 min, the average intraoperative blood loss was 180±100 mL, and the average postoperative hospital stay was 13±6 d. Of the 649 patients who underwent muscle flap reconstruction after debridement, 597 patients recovered within 2 weeks, and the primary wound healing rate was 94.4%. Twenty-three (3.5%) patients died. The median follow-up time was 25 (2-40) months. Among the remaining 632 patients, 20 recurred, with a recurrence rate of 3.1% (20/632).ConclusionPedicled muscle flap after thorough debridement of deep chest wall infection is one of the best methods to repair chest wall defect with pedicled muscle flap.
Objective To explore the effectiveness of lobulated pedicled rectus abdominis myocutaneous flap to repair huge chest wall defect. Methods Between June 2021 and June 2022, 14 patients with huge chest wall defects were treated with radical resection of the lesion and lobulated pedicled rectus abdominis myocutaneous flap transplantation for reconstruction of chest wall defects. The patients included 5 males and 9 females with an average age of 44.2 years (range, 32-57 years). The size of skin and soft tissue defect ranged from 20 cm×16 cm to 22 cm×22 cm. The bilateral pedicled rectus abdominis myocutaneous flaps in size of 26 cm×8 cm to 35 cm×14 cm were prepaired and cut into two skin paddles with basically equal area according to the actual defect size of the chest wall. After the lobulated pedicled rectus abdominis myocutaneous flap was transferred to the defect, there were two reshaping methods. The first method was that the skin paddle at the lower position and opposite side was unchanged, and the skin paddle at the effected side was rotated by 90° (7 cases). The second method was that the two skin paddles were rotated 90° respectively (7 cases). The donor site was sutured directly. Results All 14 flaps survived successfully and the wound healed by first intention. The incisions at donor site healed by first intention. All patients were followed up 6-12 months (mean, 8.7 months). The appearance and texture of the flaps were satisfactory. Only linear scar was left at the donor site, and the appearance and activity of the abdominal wall were not affected. No local recurrence was found in all tumor patients, and distant metastasis occurred in 2 breast cancer patients (1 liver metastasis and 1 lung metastasis). Conclusion The lobulated pedicled rectus abdominis myocutaneous flap in repair of huge chest wall defect can ensure the safety of blood supply of the flap to the greatest extent, ensure the effective and full use of the flap tissue, and reduce postoperative complications.
