[Indication of the use of pedicled omentum in chest surgery]

The omentum has been known to have a remarkable power of repair through neovascularization and scavenger function. Nine patients have been treated with the pedicled omentum. In 4 patients the omentum was used to obtain healing in the presence of infection. Bronchial fistulas were successfully closed in 3 patients with lung cancer and bronchial anastomotic leakage was repaired in one patient who received carinal reconstruction. In 5 patients, all of them had simultaneous resection of thoracic esophagus, the preventive use of omentum made a good result in two tracheoplasties, one pneumonectomy and one terminal tracheostomy. But one patient with esophago-tracheofistula after irradiation to esophageal cancer developed tracheal necrosis postoperatively. The omentum is useful in the case of postoperative empyema with bronchial fistula especially in patient with lung cancer. In the case of tracheobronchial resection after radiation therapy or with resection of thoracic esophagus, the suture line should be wrapped by omentum to prevent anastomotic leakage.
