Association between Examination Time and Discomfort in Unsedated Esophagogastroduodenoscopy: A Prospective Observational Study

This study revealed that in unsedated esophagogastroduodenoscopy, an increase in examination time is a significant factor contributing to increased discomfort, although the magnitude of this increase is quite small. Therefore, the clinical impact of heightened discomfort due to longer examination times is considered to be minimal. Endoscopists should prioritize adequate examination time to ensure the most accurate esophagogastroduodenoscopy.
