During endoscopic examinations of the laryngopharyngeal region, insertion of the scope induces the gag reflex, and examinations have tended to be inadequate because of the desire to minimize patient discomfort. The laryngopharyngeal region is of course under the aegis of the ear, nose, and throat (ENT) specialty, but even in the ENT field, early detection of cancers in this region has been considered extremely difficult. Detection of superficial esophageal cancers is also far from easy, requiring considerable experience.
