  • Title: Food impaction due to nutcracker esophagus.
    Author: Ladd AM, Alvarez AM, McCallum RW, Zuckerman MJ.
    Journal: Am J Med Sci; 2013 Jul; 346(1):76-9. PubMed ID: 23656923.
    Abstract:
    Nutcracker esophagus is an esophageal motility disorder characterized by the presence of hypertensive contraction waves. These waves can have very high amplitudes, but they maintain a peristaltic pattern and therefore, bolus passage is minimally affected. Esophageal food impactions are rare in nutcracker esophagus. Our patient was a previously asymptomatic man who presented with an esophageal meat impaction due to nutcracker esophagus in which high-resolution manometry played a key role in the diagnosis. Although a rare etiology, nutcracker esophagus can result in esophageal food impaction. High-resolution manometry plays a critical role in the diagnosis of specific motility disorders, even in the setting of minimal symptoms.
