Hypertensive lower esophageal sphincter

Hypertensive lower esophageal sphincter is a manometric curosity where the lower esophageal sphincter has a higher than normal resting pressure. The sphincter usually relaxes normally. A hypertensive lower esophageal sphincter may be associated with hypertensive esophageal peristalsis which is termed the nutcracker esophagus.
