“…S AMI ET AL. 13 REPORTED that in 94.0% of patients (95% confidence interval [CI]: 91.9-95.8%), endoscopy with an ultrathin endoscope was successfully completed through the nasal route and in 97.8% (95% CI: 95.6-98.9%) through the oral route. Failure in endoscopy using the nasal route is often attributable to difficult passage because of the narrow lumen, but the success rate of transnasal endoscopy with an endoscope measuring ≤5.9 mm diameter was comparable to that of standard transoral endoscopy.…”

“…[14][15][16][17] Success rate of transoral endoscopy differed between Western countries (95.9%; 95% CI: 92.6-97.8%) and Japan (99.5%; 95% CI: 98.5-99.8%), suggesting that the skill of the physicians carrying out the endoscopy is higher in Japan, where endoscopy is routinely carried out more often than in other countries. 13…”

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.

“…The technical success rate of unsedated transnasal endoscopy (TNE) is comparable to C-EGD and the former was more preferred by patients4. However, the conventional TNE devices still require dedicated endoscopy suites with specialized equipment and decontamination facilities, hence, they have limited potential for widespread use in population screening 5.…”

“…The acceptability rate of TNE was 85.2 % in a recent meta-analysis including 1597 patients; furthermore, 63 – 80 % of individuals preferred TNE to EGD for future procedures 6 7 8. Technical success rates of TNE and EGD were comparable (particularly when TNE scope diameter was < 5.9 mm) 8. TNE has also been shown to be sensitive for detecting Barrett’s Esophagus (BE) in subjects with known or highly suspected BE 9 10 11.…”

Comparative quality assessment of esophageal examination with transnasal and sedated endoscopy

Background Unsedated transnasal esophagoscopy (TNE) may offer a less expensive, mobile alternative to sedated esophagogastroduodenoscopy (EGD) for evaluations of reflux related complications. Comparisons of imaging quality by these methods are lacking. Methods Two reviewers evaluated videos of TNE and EGD procedures, performed during a community randomized study comparing endoscopic techniques. Subjects were randomized to EGD, TNE in endoscopy suite, or TNE in mobile research unit. Endoscopic quality was assessed using a validated scoring tool. Results In total, 115 videos (58 EGD, 28 endoscopy suite TNE, and 29 mobile TNE) were reviewed. Overall quality scores for TNE and EGD were excellent without a statistically significant difference (P = 0.30). There were no differences in gastroesophageal junction (GEJ) visualization scores, though EGD scored higher in esophageal passage (P < 0.05) and TNE scored higher in esophageal intubation (P < 0.05). There was no significant difference in any quality score between mobile TNE and gastrointestinal suite TNE. Conclusion Esophageal assessment with TNE or EGD was comparable in overall quality and GEJ visualization. TNE quality was not affected by procedure location. TNE is a feasible option for endoscopic assessment of reflux complications.
