Screening examination of the larynx and pharynx during upper gastrointestinal panendoscopy.

With the flexible fiberoptic esophagogastroduodenoscopes now in use, the larynx and posterior pharynx can be easily viewed during routine upper gastrointestinal endoscopy. Screening laryngeal-pharyngeal examinations were carried out during 1120 upper gastrointestinal endoscopies. Mean additional examination time was 30 sec. Thirty-nine laryngeal lesions were detected, mostly variants of chronic laryngitis. Two patients had leukoplakia, one of whom on subsequent biopsy revealed squamous cell cancer. The brief additional endoscopic time may result in the detection of early curable neoplasms. Thus a screening laryngeal-pharyngeal examination should be part of each upper gastrointestinal endoscopic examination.
