“…Our data are particularly noteworthy by addressing, for the first time, patient anxiety concerning implementation of EGD and the most painful region associated with TN endoscopy. The mean VAS score was 3.4 ± 2.1 when an endoscope was [13] found median score of 30 for the severity of discomfort on a VAS ranging from 0 to 100 mm when passing an endoscope with 5.9-mm external diameter via the TN route.…”

“…Zaman et al [9] used a spray composed of 1% phenylephrine and 4% lidocaine solution. Dumortier et al [13] administered local anesthesia to the nasal cavity by impregnating cotton gauze with 5% lidocaine and 0.002% naphazoline. Further study is required to compare various pretreatment procedures in order to determine the most appropriate pretreatment for TN endoscopy.…”

We performed a randomized prospective trial to compare unsedated endoscopy via transnasal and transoral routes using a small-caliber endoscope. Two hundred patients referred for diagnostic esophagogastroduodenoscopy (EGD) were randomly allocated to two groups: those undergoing transnasal (TN) and transoral (TO) endoscopy. We examined the insertion rate, examination duration, nasal pain, pharyngeal pain, number of occurrences of pharyngeal reflex, severity of discomfort throughout the examination, and rate of adverse events. Patients were asked to rate the severity of their pain or discomfort on a 10-cm visual analog scale (VAS). We identified statistically significant differences between the TN and TO groups in rate of insertion (95% versus 100%, respectively, P < 0.05) and examination duration (9.7 +/- 3.0 min versus 8.4 +/- 2.7 min, respectively, P < 0.005). Severity of discomfort throughout the examination was comparable in the TN and TO groups (3.0 +/- 1.8 versus 2.9 +/- 2.3, NS). Nasal bleeding occurred as an adverse event in 4.1% of patients in the TN group. Patients in the TO group were more likely than those in the TN group to prefer the present method in the subsequent endoscopic examination (99.0% versus 82.1%, P < 0.00005). These results indicated that transoral insertion is superior to transnasal insertion in endoscopy procedures performed with small-caliber endoscope.

“…8,[14][15][16][17][18] According to previous studies, successful T-EGD may depend mainly on examinee factors such as differences in individual pain sensation, differences in nasal cavity size, anesthetic preparation, or technical factors such as the type of endoscopic procedure. 19 In our study, the major cause of failure of the transnasal approach was unsuccessful transnasal insertion.…”

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 (＜35 years) and female sex were significant predictive factors for failure of the procedure. Older age (≥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 (≥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.

“…3 Topical anesthesia of the nasal passage is achieved by applying 2% to 5% viscous lidocaine with a cotton applicator or catheter 10 minutes before the procedure. 1,4,5 A vasoconstricting agent such as 0.002% naphazoline or 0.05% oxymetazoline is also applied to facilitate decongestion. Additionally, the posterior pharynx should be anesthetized with xylocaine or benzocaine spray.…”
