Abstract
Background/Aims: Interobserver variation by experience
was documented for the diagnosis of esophagitis using
the Los Angeles classification. The aim of this study was to
evaluate whether interobserver agreement can be improved
by higher levels of endoscopic experience in the diagnosis
of erosive esophagitis. Methods: Endoscopic images of
51 patients with gastroesophageal reflux disease (GERD)
symptoms were obtained with conventional endoscopy and
optimal band imaging (OBI). Endoscopists were divided into
an expert group (16 gastroenterologic endoscopic specialists
guaranteed by the Korean Society of Gastrointestinal
Endoscopy) and a trainee group (individuals with fellowships,
first year of specialty training in gastroenterology). All
endoscopists had no or minimal experience with OBI. GERD
was diagnosed using the Los Angeles classification with or
without OBI. Results: The mean weighted paired κ statistics
for interobserver agreement in grading erosive esophagitis
by conventional endoscopy in the expert group was better
than that in the trainee group (0.51 vs 0.42, p<0.05). The
mean weighted paired k statistics in the expert group and in
the trainee group based on conventional endoscopy with OBI
did not differ (0.42, 0.42). Conclusions: Interobserver agreement
in the expert group using conventional endoscopy was
better than that in the trainee group. Endoscopic experience
can improve the interobserver agreement in the grading of
esophagitis using the Los Angeles classification. (Gut Liver
