“…Based on the above observations, we believe that formation of the LEMR and progression from LEMR to stricture are associated with reflux esophagitis [7,[10][11][12][13][14]. The data from the 22 patients analyzed in the current study strongly support this view.…”

Among 390 patients with endoscopically verified lower esophageal mucosal ring (LEMR), 22 cases were identified with previous or subsequent radiologic examinations of the esophagogastric region. Among these, it was found that 2 cases of LEMR had developed from a normal esophagus. In 3 patients, there was increasing stenosis of the LEMR. In 8 cases, the LEMR was transformed into an esophageal stricture. In 10 of the 13 cases, esophagitis of varying degree was present endoscopically. In the 9 patients exhibiting no change in the LEMR, only 1 patient had esophagitis. The data suggest that there is a potential progression from normal esophagus to lower esophageal ring to esophageal stricture that occurs in association with reflux esophagitis.

“…Confusion exists because the terms "lower oesophag-eal webs" and "lower oesophageal rings" had been used synonymously, as pointed out by Tedesco and Morton (5). In contrast to lower oesophageal webs, the diagnosis of lower oesophageal rings (5)(6)(7)(8)(9) is based upon the following features: 1. Sharply demarcated circular constriction just above the diaphragm on X-ray examination and endoscopy, 2. resistence on endoscopy, and 3. squamous epithelium covering the oral and columnar epithelium the aboral side of the ring associated with submucosal fibrosis.…”

A 51-year-old male suffering from dysphagia due to a typical lower oesophageal web is described. The diagnosis was suspected upon Xray examination which revealed an asymmetrical stenosis of the oesophageal lumen 4 cm above the cardia. Endoscopy demonstrated a semilunar, pliable, opaque and partially translucent membrane which narrowed the oesophageal lumen. It was easily torn and removed by a biopsy forceps.Histological examination of the tissue revealed squamous epithelium of the oesophagus on both sides of the membrane with normal submucosa, thus confirming-the diagnosis of a lower oesophageal web.

“…Inflammation associated with the lower esophageal ring has been described by numerous investigators. 15,10,14,16,18,27 Barrett,' Johnston, 10 Mustard,14 and Postlethwait "6 believe the ring develops in response to reflux esophagitis.…”
