Evaluation of Transnasal Esophagogastroduodenoscopy as a Surveillance Endoscopy in a General Medical Checkup

ABSTRACT

BACKGROUND/AIMS: Transnasal esophagogastroduodenoscopy (T-EGD) has been reported to be well tolerated and is known to reduce patient discomfort that occurs with conventional EGD (C-EGD) performed via an oral route. We aimed to evaluate factors that influence preferences for T-EGD as a surveillance EGD in a general medical checkup. MATERIALS AND METHODS: A total of 658 subjects (median age, 49 years; 45% men) underwent T-EGD procedures by 8 endoscopists using a 5.2-mm diameter endoscope. All examinees and endoscopists were asked to assess the T-EGD examinations using the post-endoscopy questionnaire. The post-endoscopy questionnaire included a 10-point visual analogue scale, which asked the patient to place a cross on the line according to examinee's or endoscopist's experience of the endoscopy procedure. Zero represented the worst experience and 10 the best experience. RESULTS: T-EGD was feasible in 96.6% of the subjects. Younger age ( or =35 years) or male examines preferred T-EGD as the modality for the next examination. The endoscopist's overall discomfort level was higher in the beginner group than in the expert group. CONCLUSIONS: The T-EGD may be better tolerated than C-EGD and offers a more comfortable surveillance endoscopic procedure to older (> or =35 years), male, or sedated C-EGD-experienced examinees in a general medical checkup. More experience with and education about T-EGD may help to improve the tolerance of the beginner group of endoscopists.
