Endoscopic techniques used in obturation of the bronchus by metastasis of leiomyosarcoma of the retrocecal space. Clinical observation

Obturation of the bronchial tree in oncological patients leading to labored breathing, tachypnea and asphyxiation is more frequent in primary malignant lesions of the airways: trachea, primary and lobar bronchi. In case of contraindications for surgical treatment, endoscopic techniques of recanalization of airways can be used. The most common are physical techniques such as argon plasma coagulation and cryodestruction. However, in this clinical observation of primary bronchus obturation by leiomyosarcoma metastasis we used endoloop resection.
