Protracted hiccups (singultus) following brainstem stroke caused esophageal dilation, aperistalsis, and poor emptying. These esophageal dysfunctions resolved when hiccups ceased, differing from achalasia.

Area of Science:

  • Gastroenterology
  • Neurology
  • Esophageal Motility Disorders

Background:

  • Hiccups (singultus) are typically transient; prolonged cases, especially post-stroke, are rare.
  • Previous studies on hiccups and esophageal function are limited, mainly to manometry.

Observation:

  • A patient with lateral medullary infarction developed persistent hiccups.
  • Esophageal function was assessed using manometry, radiology, ambulatory pH monitoring, and scintigraphy.

Findings:

  • During hiccups: esophageal body dilation, aperistalsis, absent lower esophageal sphincter relaxation, poor emptying, and low distal esophageal pH.
  • These abnormalities normalized when hiccups resolved.
  • Findings were compared to esophageal achalasia.

Implications:

  • This study details comprehensive esophageal dysfunction during protracted hiccups.
  • It highlights the potential for significant, albeit reversible, esophageal motility changes linked to neurological events.
  • The findings aid in understanding hiccup pathophysiology and differential diagnosis from achalasia.
