Omentum in the management of thoracic surgery: especially its application to tracheobronchial surgery

Omentum is now not only policeman of the abdomen but also of the thorax. We applied omental pedicle flap in the management of 14 patients with thoracic surgery including chest wall reconstruction, empyema, thoracic skeletal infection and tracheobronchial problems. Especially, tracheobronchial reconstruction using omental pedicle flap for the patient combined with lung cancer (T4N2M0 STAGE IIIB) and asthma under steroid therapy was reported. The case was 71-year-old man with complaint of hemosputum. He had 5-6 year history of bronchial asthma with disturbed pulmonary function of % VC 44%, FVC1.0% 37%. Bronchoscopic study revealed the tumor invading the right side of trachea originating from right upper bronchus with histological diagnosis of moderately differentiated squamous cell carcinoma. Preoperatively, he experienced a heavy asthma attack which was controlled by steroid administration. Following extended right sleeve upper lobectomy, we applied omental pedicle flap around the reconstructed portion for the protection of infection, impaired wound healing due to postoperative steroid therapy and strong tension at anastomoses. Postoperative course was satisfactory. We suggest omental pedicle flap is an effective surgical armamentarium in the management of tracheobronchial surgery for the patient with strong anastomotic tension, immunocompromised condition, preoperative irradiation at bronchial stump and use of drug causing delayed wound healing (steroid, anticancerous drug etc).
