To emphasize the utility of office-based transnasal esophagoscopy (TNE) in the evaluation of patients with swallowing complaints, we present 2 case reports and a review of the literature. The 2 patients both presented with complaints of chronic dysphagia, globus sensation, and a sensation of "food sticking" with swallowing. The patients were counseled to undergo esophagoscopy. Informed consent was obtained. The nasal cavities and pharynx were anesthetized with topical 4% lidocaine hydrochloride solution. Transnasal esophagoscopy was performed. The procedure was well tolerated by the patients. Esophagoscopy revealed diverticuli in various segments of the esophagus, including the midesophageal and distal areas. The cause of the patients' complaints could be well attributed to the endoscopic findings. No morbidity was associated with the TNE examination. A review of the literature concerning office-based TNE was performed. We found no published reports of middle or distal esophageal diverticuli detected on routine office TNE. We conclude that transnasal esophagoscopy is a relatively safe and efficient tool that can be used in the office setting for evaluation of swallowing complaints.
