Abstract

BACKGROUND/AIMS
Some people have difficulty tolerating upper endoscopy. The cause of and risk factors for this are not well known. The aim of this study was to investigate the factors involved in poor cooperation during screening upper endoscopy.
METHODS
A total of 4,422 subjects who underwent a health inspection with upper endoscopy carried out by a single experienced endoscopist were included. We retrospectively investigated subjects' self-reporting questionnaires and medical records, including endoscopic and histologic findings. The examinees' cooperation and the completeness of endoscopic examination were evaluated based on the operator's subjective judgment.
RESULTS
Examinee cooperation during the endoscopic procedure was poor in 358 out of 4,422 subjects (8.1%). Of the subjects with poor cooperation, the endoscopic examination was incomplete in 36 subjects (10.1%). Multivariate analysis revealed that young age (< 40 years), female sex, high body mass index (â‰¥ 25), hiatal hernia, and procedural sedation using midazolam were independent risk factors for poor cooperation.
CONCLUSIONS
Cooperation during screening upper endoscopy was poor in a considerable number of examinees. Endoscopists must keep in mind that examinee cooperation is more likely to be poor in the young, obese people, women, patients with hiatal hernias, and those who receive procedural sedation.
