To review and summarize the current literature on transnasal esophagoscopy, and to compare information with conventional esophagoscopy.
Data Sources
Medline (Ovid), book chapters.
Review Methods
A thorough review of the literature using the Medline database was performed with the following search terms: esophagoscopy, transnasal esophagoscopy, ultrathin endoscopy, and esophagoscope.
Results
The literature seems to support the equivalence of transnasal esophagoscopy and conventional esophagoscopy in image quality and diagnostic capability. It also points to some potential advantages of transnasal esophagoscopy.
Conclusions
Transnasal esophagoscopy is a useful tool for accurate diagnosis and can be used in a variety of office procedures.
