Endoscopic electroresection (ER) with a high-frequency cutting loop was used in 10 patients with recurrent or local extensive invading tumors. The procedures were exclusively palliative, Five patients had squamous cell carcinoma, four had adenoid-cystic carcinoma, and one adenocarcinoma. All patients had severe dyspnea and inspiratory stridor prior to ER. A total of 89 resections were performed, varying from 1 to 33 treatments for each patient. All patients experienced a significant improvement in respiratory function after ER. The complication rate was low. We consider ER to be a safe and efficient method in the palliation of patients with otherwise incurable tracheobronchial tumors.
