Esophagoscopy, flexible, transoral, is a medical procedure that involves the use of a flexible endoscope to visualize the esophagus. This procedure is specifically designed for the removal of tumors, polyps, or other lesions using a snare technique. The flexible endoscope is introduced through the mouth and carefully advanced into the esophagus, allowing for a thorough examination of the velopharyngeal closure, the base of the tongue, and the hypopharynx. During the procedure, the motion of the vocal cords is observed, and the pharyngeal musculature is evaluated to ensure proper function. As the endoscope reaches the cricopharyngeus, the patient may be instructed to burp or swallow, which aids in the smooth passage of the scope through the esophagus to the gastroesophageal junction. Any abnormalities encountered during this examination are meticulously noted. Following the identification of the tumor, polyp, or lesion, the procedure utilizes a wire snare loop, which is placed around the targeted lesion. This loop is then heated to effectively shave off and cauterize the lesion. The removal of lesions can be performed in one single placement of the snare, known as en bloc removal, or in a piecemeal fashion, which necessitates multiple applications of the snare technique. This procedure is critical for diagnosing and treating various esophageal conditions, ensuring that any abnormal growths are safely excised while minimizing potential complications.
