Reconstruction of large full thickness chest wall defects following resection of malignant tumors.

BACKGROUND/AIM: Full-thickness chest wall resection is the well-established treatment for primary or metastatic chest wall tumors. Adequate surgery with large resections is always needed to achieve a radical resection in healthy tissues, leading to optimal local control of the disease. The purpose of this study is to present our experience in chest wall reconstruction after major tumor resection.

PATIENTS AND METHODS

Between January 2006 and January 2010, 18 consecutive patients who underwent major chest wall resections for primary or metastatic chest wall tumors were studied. All had resection of at least three ribs and immediate reconstruction. Surgical procedures, extent of the resection, resulting defects and postoperative morbidity and mortality were discussed.

RESULTS

Surgical indications included primary, recurrent and metastatic chest wall neoplasms, sarcoma and recurrent breast cancer were the most frequent diagnoses. Resection of 3 ribs was performed in 8 patients, while resection of more than 3 ribs was performed in 10 patients. Resection of sternum and adjacent costal cartilages was performed in one patient, right chest wall resections were performed in 7 patients while left chest wall resections were performed in 10 patients. Immediate repair of the defects was performed in all cases, all patient had placement of prosthesis either polypropylene or polytetrafluroethylene, 3 patients had methylacrylate in addition to the prosthesis. Coverage was achieved using myocutaneous flaps in 7 patients. Mechanical ventilation was needed in 11 patients with a mean duration of ventilation 2.2±1.8 days (range between 1- 6 days). No 30-days mortality was recorded. Four patients 22.2% developed complications, 2 patients need prolonged mechanical ventilation for respiratory insufficiency and 2 patients had partial flap necrosis and wound infection. Mean hospital stay was 10.1±3.2 days.

CONCLUSION

Immediate reconstruction of large full thickness chest wall defects following resection of malignant tumors should be performed in all cases. Our series proved that reconstruction can be performed safely with no recorded mortality and low morbidity. Polypropylene mesh or polytetrafluroethylene (PTFE) were used with equal results, myocutaneous flaps were used efficiently for soft tissue coverage if needed.
