OBJECTIVE. The purposeof this investigationwasto determinethe prevalenceof lower esophagealmucosal rings and to correlate the relationship between these mucosal rings and thepresenceandanatomiclevel of symptomsevokedusinga marshmallowbolus. SUBJECTS AND METHODS. Our prospective studyincluded130 patientswho under went bariumexaminationof the esophagus. All patientscompleteda questionnaireregarding the anatomic location of their symptoms of dysphagia. In addition to a multiphasic examina tion of the esophagus, all patients also underwent fluoroscopic observation and videotaping while swallowing a marshmallow bolus; any symptoms that were provoked were recorded.RESULTS. Lower esophageal mucosalringswere shownin 26 (20%) of the 130 patients. The diameterof the ringswas 9â€"12 mm in six patients,13â€"20 mm in 18 patients,and larger than 20 mm in two patients. In 16 (62%) of the 26 patients, a marshmallow bolus became im pacted at the ring; the impaction caused dysphagia in 12 (75%) of the I6 patients. In these 12 patients, dysphagia was referred to the neck in seven,the sternal angle in two, the mid chest in two, and the lower chest in one patient. None of the 12 patients had a pharyngeal or cervical esophageal abnormality that would account for their symptoms.CONCLUSION. Becauseproximal referral of symptomsis common in patientswith loweresophageal mucosalrings,a thoroughradiographicexaminationof theentireesophagus and esophagogastricregion is required regardlessof the level of their swallowing complaints.

“…Effective detection by this method of esophageal narrowings, such as mucosal ring and peptic stricture, depends on obtaining maximal distention of the esophagogastric region, which is achieved by having the patient swallow barium rapidly and by performing various respiratory maneuvers (Fig. 2) [4].…”

“…However, optimal double-contrast films are not always obtained since gaseous distention is transient. This is a particular problem in the esophagogastric region, where double-contrast films may fail to evaluate the area adequately [4,8].…”

The radiographic examination of the esophagus to determine structural and/or functional causes of dysphagia is best performed with multiple techniques. These include full-column studies to produce distended films with or without the use of a solid bolus, mucosal relief films to identify mucosal defects such as esophagitis or the presence of varices, double-contrast films, and motion recording (fluoroscopy). The efficacy of each technique depends on the quality of the study and the specific disorder to be detected. Esophageal lesions producing dysphagia are classified into extrinsic structural lesions, intrinsic structural lesions, and esophageal motility disorders. Radiographic studies are the preferred screening techniques for patients with dysphagia. Although not as sensitive for the evaluation of mucosal lesions, radiographic studies are superior to endoscopy for the detection of abnormal motility, esophageal rings, and strictures.
