Nutcracker esophagus (NE) is a primary esophageal motility disorder characterized by high-wave amplitude at the distal esophagus. The aim of this study was to analyze patients with NE and determine the relationship between distal esophageal contraction amplitude and lower esophageal sphincter (LES) pressure. Esophageal manometry tracings of patients with NE, defined as the presence of distal contraction amplitude of more than 182 mmHg after wet swallow, were analyzed.

Background: The nutcracker esophagus, a primary motor disorder, is frequently associated with noncardiac chest pain.
Aim: To study the clinical, endoscopic, manometric, and pathological features and 24 h acid reflux in patients with nutcracker esophagus.
Patients And Methods: Eighty patients (63 females, aged 26 to 70 years) with nutcracker esophagus, defined as the presence of contraction waves of more than 180 mmHg in the esophageal manometry, were studied.

The nutcracker esophagus, a primary motor disorder, is frequently associated with noncardiac chest pain. However, there are no data on whether its diagnosis, as in other esophageal motility disorders, is delayed. Since the disorder is frequently heralded by alarming symptoms such as chest pain and dysphagia, diagnosis should be made as soon as possible.

A review of our 402 motility records of patients undergoing evaluation of noncardiac chest pain identified 40 patients with the diagnosis of nutcracker esophagus. Gastroesophageal reflux was found in 13 of 20 patients (65%) who underwent pH studies, and endoscopy detected one patient with erosive esophagitis. Thus, at least 14 (35%) of our nutcracker esophagus patients had evidence of reflux.
