A Case of Tracheocarinal Stenosis due to Metastatic Mediastinal Lymph-node Carcinoma of Unknown Origin Treated with Electrosurgery and Dynamic Stent

Abstract

A 57-year-old man with metastatic mediastinal lymph-node carcinoma of unknown origin invading the trachea complained of bloody sputum and dyspnea. Bronchoscopic examination revealed tracheocarinal stenosis caused by the malignant tumor. Transbronchoscopic electrosurgery was performed four times to eliminate the dyspnea. A dynamic stent was inserted under general anesthesia. The electric scalpel and forceps designed for the flexible bronchoscope were useful for treating the neoplastic stenosis. The dynamic stent was useful for improving the quality of life in this case.
