A New Trend in the Management of Esophageal Foreign Body: Transnasal Esophagoscopy.

Abstract

(1) To analyze the outcomes of patients with esophageal foreign body managed by transnasal esophagoscopy. (2) To review the value of lateral neck X-ray. Case series with chart review. Tertiary referral center, Shin Kong Wu Ho-Su Memorial Hospital, Taipei, Taiwan. Lateral neck X-ray was used for initial screening in patients suspected of having an esophageal foreign body between 2007 and 2013. Rigid esophagoscopy was used as standard for further investigations before July 2010 and transnasal esophagoscopy after July 2010. From January 2007 to June 2010, 43 patients who were suspected of having an esophageal foreign body under lateral neck X-ray received rigid esophagoscopy, 31 of whom were found to have an esophageal foreign body. From July 2010 to December 2013, 302 patients underwent transnasal esophagoscopy, and an esophageal foreign body was noted in only 52 of these patients. In the 302 patients who underwent transnasal esophagoscopy, the sensitivity and specificity of having an esophageal foreign body by lateral neck X-ray were 59% and 83%, respectively. The introduction of transnasal esophagoscopy has changed the diagnosis and management for an esophageal foreign body. Transnasal esophagoscopy is a quick and safe procedure that can be performed under local anesthesia. Transnasal esophagoscopy could replace lateral neck X-ray to become the initial screening procedure and a useful treatment for patients with an esophageal foreign body.
