Esophagoscopy, flexible, transoral, is a medical procedure that involves the use of a flexible endoscope to visualize and treat conditions affecting the esophagus, particularly esophageal varices. Esophageal varices are abnormally dilated blood vessels located within the esophageal wall, often resulting from portal hypertension, which is frequently associated with liver cirrhosis. During the procedure, the endoscope is inserted through the mouth and carefully advanced into the esophagus, allowing for a thorough examination of the upper digestive tract. The procedure includes evaluating critical areas such as the velopharyngeal closure, the base of the tongue, and the hypopharynx, as well as assessing vocal cord motion and pharyngeal musculature. As the endoscope reaches the cricopharyngeus, the patient may be instructed to swallow or burp to facilitate the passage of the scope. The endoscope is then advanced through the entire length of the esophagus to the gastroesophageal junction, where any abnormalities can be documented. Following the examination, the endoscope is withdrawn, allowing for a comprehensive review of the esophageal circumference. In the context of treating esophageal varices, two primary methods are utilized: injection sclerotherapy, which involves injecting a sclerosing solution to shrink the varices, and band ligation, where a snare is used to place an elastic band around each varix, effectively strangling the vein to prevent bleeding.
