Abstract

The Chicago Classification version 3.0 (CC v 3.0) defines hypercontractile peristalsis as Jackhammer esophagus (JE); Nutcracker esophagus (NE) is no longer recognized. Data regarding patient characteristics and treatment response for JE versus NE are limited.We aimed to compare demographic characteristics, high resolution manometry (HRM) features, clinical presentation, management strategies, and treatment outcomes in patients with JE versus NE. We performed a retrospective analysis of adult patients diagnosed with NE (CC v 2.0) or JE (CC v 3.0) by HRM from January 2012 to August 2015. Demographics, symptoms, treatments, and response to therapy (none or partial/complete) were ascertained by chart review, for statistical comparisons. In 45 patients with JE and 29 with NE, there was no significant difference in rate of dysphagia (73% and 59%) or chest pain (44% and 59%). Treatment data were available in 29 JE (smooth muscle relaxants in 4, pain modulators in 3, botulinum toxin injection (BTX) in 10, endoscopic dilation in 5, multimodal treatment in 7), and 20 NE patients (smooth muscle relaxants in 2, pain modulators in 2, (BTX) in 6, endoscopic dilation in 3, multimodal treatment in 7). Follow-up data on 26/29 JE and 20/20 NE patients showed similar treatment response (96.4% vs. 82.1%, p = 0.08) after mean follow-up of 11.2 and 11 months, respectively. There were no major differences for JE versus NE in demographics, symptoms, or type of and response to therapy. Larger prospective, controlled trials are needed to clarify the clinical significance and response to treatment in JE and NE.
