Purpose: Abdominal ultrasound (US) can visualize the esophagogastric junction (EGJ) as a hyperechoic area in the dorsal portion of the lateral segment of the liver. We prospectively evaluated the EGJ using US elastography (US-EG) in patients with reflux esophagitis (RE) to examine prediction of distal esophageal function. Methods: Of 108 patients undergoing US-EG and esophagogastroduodenoscopy, 102 in whom the EGJ was observed for ≥ 15 s were included. The subjects were divided into a RE group (n = 41, Grade M/A/B:24/13/4 according to modified Los Angeles Classification) and a non-RE group (n = 61). Direct strain elastography (LOGIQ E9, GE Healthcare), which gives a semi-quantitative elasticity index within a region of interest including the lateral segment, was used as a standard for measurement of the change in stiffness (CS) at the EGJ. Results: The number of CS as determined by US-EG was 6.0 (5.5–6.7) in the RE group and 8.6 (6.6–10.0) in the non-RE group (P < 0.0001). In ROC analysis, the AUC was 0.8415 for diagnosis of RE using the number of CS. At a cut-off of 7.7, the sensitivity, specificity, and accuracy for diagnosis were 92.7, 65.6, and 74.5%, respectively. Conclusion: The presence of RE can be predicted based on US-EG.
