Palliation of Tracheobronchial Carcinoma: The Role of Cryosurgery

Bronchoscopy is a common day case procedure that can aid in the diagnosis and treatment of tracheobronchial disorders. The controlled application of extreme cold through a bronchoscope to endobronchial lesions (malignant and benign) is known as endobronchial cryosurgery. This procedure improves respiratory function and reduces shortness of breath and is performed in a cycle of three treatments. This article describes the instrumentation required, how cryosurgery is performed and how endobronchial cryosurgery can improve the patient's functional status and survival.
