Abstract

It is often difficult to diagnose cases of globus pharyngeus or a foreign body in the pharynx because no abnormal findings are found when observing the pharynx and larynx. In such cases, it is effective to observe the esophagus using a conventional rhinolaryngoscope. <br>Method: After ordinary laryngoscopy, the tip of the endoscope is inserted into the esophagus. The inside of the esophagus is observed while the esophageal lumen is expanded by swallowing saliva or a small amount of water. <br>Results: Esophageal cancer, esophageal foreign bodies and steakhouse syndrome are observed. <br>Discussion: Although this method is uncomplicated, it is an effective examination because it allows immediate diagnosis when abnormal findings are observed. However, observation of the esophagus using a laryngeal endoscope has limitations in range and accuracy, so prudence is required in evaluating and making decisions when no abnormal findings are observed.
