Esophagoscopy, flexible, transoral; with ablation of tumor(s), polyp(s), or other lesion(s) (includes pre- and post-dilation and guide wire passage, when performed)

Esophagoscopy is a medical procedure that involves the use of a flexible endoscope to visually examine the esophagus, which is the tube that connects the throat to the stomach. This procedure is performed transorally, meaning the endoscope is inserted through the mouth. During the esophagoscopy, the physician evaluates various anatomical structures, including the velopharyngeal closure, the base of the tongue, and the hypopharynx. The examination also includes observing vocal cord motion and assessing the pharyngeal musculature. The endoscope is advanced through the esophagus to the gastroesophageal junction, allowing for a thorough inspection of the esophageal lining for any abnormalities such as tumors, polyps, or other lesions. In cases where lesions are identified, the procedure includes the ablation of these growths. Ablation refers to the removal or destruction of tissue, which in this context is achieved using a laser device. Prior to the ablation, if necessary, the esophagus may be dilated to facilitate the procedure. This dilation can be accomplished through the insertion of a guidewire and the use of rigid tubes or a balloon catheter. The ablation process involves carefully targeting the lesions with the laser as the endoscope is retracted, ensuring complete destruction of the abnormal tissue. Following the ablation, the esophagus is re-examined to confirm that all lesions have been effectively treated and to check for any potential injuries resulting from the procedure. This comprehensive approach ensures that the esophagus is thoroughly evaluated and treated as needed.
