Open tube versus flexible esophagoscopy in adult head and neck endoscopy.

Open tube esophagoscopy is the mainstay of otolaryngic esophageal examination. Over the last 30 years flexible endoscopes have become popular and are challenging the open tube esophagoscope for use in otolaryngic practice. This study examines all open tube esophagoscopies performed on adult patients at the University of Pennsylvania over an 8-year period for the diagnosis and treatment of foreign bodies, strictures, functional disorders, and carcinoma. Open tube esophagoscopy is most useful for foreign body extraction, examination of the cervical esophagus, and dilation of pliable strictures. For most other indications flexible esophagoscopy provides improved visualization with lower morbidity. For patients with squamous cell carcinoma of the head and neck we found a 1.4% incidence of secondary esophageal malignancies and a 28% incidence of false-negative barium swallow studies. We recommend esophagoscopy for all patients with carcinoma of the upper aerodigestive tract. The otolaryngologist should be adept at both flexible and open tube esophagoscopy in order to allow optimal examination of and therapeutic intervention in the upper aerodigestive tract.
