A lower esophageal ring (LES) is a common anomaly of the esophagus in which a ring-shaped band of muscle fibers forms at the bottom of the esophagus. This abnormal process can contribute to obstruction of food passage, causing dysphagia, or difficulty swallowing, and regurgitation, or the backflow of food from the stomach or esophagus into the mouth. Although most people with LES experience no symptoms, some may have difficulty swallowing, especially when eating quickly.<\/p>\n
