Laryngo-Broncho-Esophagoscopy (LBE) is a comprehensive endoscopic procedure that involves the simultaneous examination of the larynx, bronchi, and esophagus. This intricate diagnostic technique is commonly employed by otolaryngologists and pulmonologists to assess and diagnose various conditions affecting these interconnected structures. Utilizing a flexible or rigid endoscope, healthcare professionals can visualize the entire upper respiratory tract, including the vocal cords, trachea, bronchi, and the esophagus. LBE plays a crucial role in identifying abnormalities, such as tumors, strictures, or infections, as well as facilitating interventions like biopsies or foreign body removal. This procedure not only offers a holistic assessment of the upper airway but also allows for targeted treatments, making it a valuable tool in managing complex cases involving the larynx, bronchi, and esophagus.
