A Case of Lower Esophageal Ring with Dysphagia / 대한소화기내시경학회지

Lower esophageal ring are uncommon. We experienced a case of lower esophageal ring in a 51-year-old man who had intermittent swallowing difficulty for 2 years. Endoscopy revealed a circumferential narrowing at 34 cm from the incisors and congested and eroded mucosa was noted proximal to the ring. Esophagography revealed an elevation of G-E junction above the diaphragm and a reflux of dye from the stomach into the esophagus with thickened and irregular esophageal wall.
