Conditions

Esophageal motility disorders(EMD)

Interventions

Onigiri esophagography The addition of onigiri esophagography to conventional barium esophagography requires an additional examination time of about 2 minutes and a radiation exposure of about 20 mGy

Design outcomes

Primary

Measure	Time frame
Increase in sensitivity of EMD screening by onigiri esophagography compared with conventional barium esophagography	—

Secondary

Measure	Time frame
-Sensitivity and specificity of onigiri esophagography for EMD screening -Interobserver agreement rate of onigiri esophagography -Diagnostic ability of onigiri esophagography using obstruction level (ROC analysis) -Diagnostic ability of onigiri esophagography for each EMD -Correlation between symptom scores and onigiri esophagography -Multivariate analysis of factors related to diagnostic ability -Increased diagnostic ability for EMD by the findings including wave appearance and weak peristalsis -Diagnostic ability for EMD by the length of dispersed onigiri in the esophagus	—
