Abstract
- Hypercontractile esophagus (HE), also known as jackhammer esophagus, is an esophageal motility disorder. Nowadays, high-resolution manometry (HRM) is used to diagnose the disorder. According to the latest iteration of the Chicago classification, HE is present when at least 2 out 10 liquid swallow-induced peristaltic waves have an abnormally high Distal Contractile Integral. In the era of conventional manometry, a similar condition, referred to as nutcracker esophagus, was diagnosed when the peristaltic contractions had an abnormally high mean amplitude. Although the HRM diagnosis of HE is relatively straight-forward, effective management of the disorder is challenging as the correlation with symptoms is variable and treatment effects are dubious. In this mini-review, we discuss the most troublesome uncertainties that still surround HE, in the light of new data on etiology and epidemiology published in this issue of Neurogastroenterology and Motility.<br /> (© 2020 The Authors.
