      Transnasal endoscopy with an ultrathin endoscope has been reported to be highly acceptable even without any sedative measures. Poor image quality and complex manipulation have been reported as shortcomings of this type of endoscopy compared with standard transoral endoscopy. However, image quality has improved markedly with the latest ultrathin endoscopes. To investigate the status of clinical use of endoscopes, we recently conducted a questionnaire survey involving 149 facilities (98 in Japan and 51 overseas). In Japan, transnasal endoscopes were being used primarily in clinics (34% in clinics and 9% in hospitals). Overseas, however, transnasal endoscopes were seldom used (1% in hospitals and 0% in clinics). This may be attributable to the complex pretreatment and more challenging manipulation required for transnasal endoscopes. However, it is evident that transnasal endoscopes are highly acceptable for patients. If the pretreatment required is simplified and healthcare physicians improve their skills and understanding, this type of endoscopy will have high potential for common use.
