Incomplete upper esophageal sphincter (UES) relaxation is not well understood. We compared clinical and manometric characteristics of patients with normal and abnormal UES relaxation. Consecutive patients (n = 208) underwent manometric evaluation of the lower esophageal sphincter (LES), esophageal body, and UES/pharynx. The patients were divided into those with abnormal UES relaxation (residual pressure >6.7 mmHg) (n = 21) and normal relaxation (n = 187). Clinical and manometric profiles were… CONTINUE READING
