BMC Gastroenterology

Table 3 Patient satisfaction when the procedure was performed by an expert or non-expert endoscopist

	Expert endoscopist n = 25	Non-expert endoscopist n = 120	*P-value
Patient satisfaction	22 (88.0%)	103 (85.8%)	0.53
Pain score	2 (0–6)	3 (0–7)	0.04
Physician satisfaction	19 (76.0%)	92 (80.0%)	1.00
Willing to repeat peroral endoscopy with an UT-EGD	24 (96.0%)	115 (95.8%)	0.69

Data are presented as median (range) or number (percentage)
Abbreviations: UT-EGD, ultrathin esophagogastroduodenoscopy
Expert endoscopists are defined as those who have been certified by the Japan Gastroenterological Endoscopy Society as endoscopy specialists
*P-value was calculated using the chi-square test or Fisher’s exact test for categorical data and the
t-test or the Mann–Whitney U test for continuous data
The pain score, patient satisfaction rate, or patient willingness to undergo repeat endoscopy were not significantly different between patients who underwent EGD using the EG-740 N or GIF-XP290N endoscope (Table 4)
