The hypertensive lower esophageal sphincter is an infrequent primary esophageal motor disorder characterized by elevated mean lower esophageal sphincter pressure (greater than or equal to 3 SD from that of controls), sphincter relaxations greater than 75%, and normal peristaltic activity in the esophageal body. This disorder is frequently associated with the nutcracker esophagus. We report our clinical and manometric experience with the isolated hypertensive lower esophageal sphincter (i.e., unassociated with other motor disorders), which constituted 2.7% of all patients who complained of dysphagia or chest pain referred for manometry during the period from October 1982 to February 1991.
高血压性食管下括约肌是一种罕见的原发性食管运动障碍，其特征为食管下括约肌平均压力升高（比对照组高出或等于3个标准差）、括约肌松弛超过75%以及食管体部蠕动活动正常。这种疾病常与胡桃夹食管相关。我们报告了孤立性高血压性食管下括约肌（即与其他运动障碍无关）的临床和测压经验，在1982年10月至1991年2月期间因吞咽困难或胸痛而转诊进行测压的所有患者中，孤立性高血压性食管下括约肌患者占2.7%。
