Plastisch-chirurgische Rekonstruktion von Defekten der Thoraxwand nach Onkologischen Resektionen: Interdisziplinäre Strategien

In defect reconstruction following radical oncologic resection of malignant chest wall tumors, adequate soft-tissue reconstruction must be achieved along with function, stability, integrity, and aesthetics of the chest wall. The purpose of this retrospective analysis was to evaluate the oncoplastic concept following radical resection of malignant chest wall infiltration with an interdisciplinary approach. Between 1999 and 2005, 36 consecutive patients (nine males, 27 females, mean age 55 years, range 20-78) were treated with resection for malignant tumors of the chest wall. Indications were locally recurrent breast carcinoma (patient n=22), thymoma (n=1), and desmoid tumor (n=1). Primary lesions of the chest wall were spinalioma (n=1), sarcoma (n=7), and non-small-cell lung cancer (n=2). There were distant metastases of colon and cervical cancer in one patient each. Soft-tissue reconstruction was carried out using primary closure (n=1), external oblique flap (n=1), pectoralis major myocutaneous flap (n=3), latissimus dorsi myocutaneous flap (n=18), vertical or transversal rectus abdominis myocutaneous flap (n=9), free tensor fascia lata- flap (n=6), trapezius flap (n=1), serratus flap (n=1), and one filet flap. In 15 reconstructive procedures microvascular techniques were used. An average of 3.4 ribs were resected. Stability of the chest wall was obtained with synthetic meshes. The latissimus dorsi flap is considered the flap of choice in chest wall reconstruction. However, alternatives such as pectoralis major flap, VRAM/TRAM flap, free TFL flap, and serratus flap must also be considered. Low mortality and morbidity rates allow tumor resection and chest wall reconstruction even in a palliative setting.
