Symptomatic Esophageal Mucosal Ring Treated by Endoscopic Balloon Dilatation

The esophageal mucosal ring, otherwise known as Schatzki’ ring or B ring is a thin, diaphragm like, circumferential mucosal fold that protrudes into the lumen of the gastroesophageal junction. Symptomatic esophageal mucosal ring is found in only 0.5% of patients who undergo an esophagogram. In Korea, symptomatic esophageal mucosal ring of adult is very rare. A 66-year-old man was admitted to the hospital with progressive dysphagia of five months standing. The endoscopy revealed a mucosal ring with a narrowed esophageal lumen of about 4mm. Herein, we report a case of endoscopic balloon dilatation using controlled radial expansion (CRE) balloon under fluoroscopic control.
