This study investigated upper esophageal sphincter (UES) dysfunction in dysphagia patients. Elevated UES pressures were found in some patients, suggesting potential treatment targets for swallowing difficulties.

Area of Science:

  • Gastroenterology
  • Otolaryngology
  • Swallowing Disorders

Background:

  • Dysphagia is a common symptom impacting quality of life.
  • Upper esophageal sphincter (UES) dysfunction can contribute to swallowing difficulties.
  • Radiographic abnormalities of the UES are often associated with dysphagia.

Purpose of the Study:

  • To determine manometric patterns in dysphagic patients with radiologic evidence of UES dysfunction.
  • To correlate UES manometric findings with radiographic abnormalities.
  • To identify potential therapeutic targets for UES-related dysphagia.

Main Methods:

  • Nineteen patients with radiographic UES abnormalities underwent manometry.
  • Measurements included UES tonic pressure and pharyngoesophageal water swallow dynamics.

  • Results were compared to a control group of 67 healthy volunteers.

    • Main Results:

    • Six of 19 patients exhibited elevated UES tonic pressures.
    • No patients were diagnosed with UES achalasia.
    • Cricopharyngeal impression in others may indicate hypertrophy or impaired UES opening.

    Conclusions:

    • Elevated UES tonic pressure is a manometric pattern observed in some dysphagic patients with UES dysfunction.
    • Cricopharyngeal myotomy may be a viable treatment for patients with manometric UES hypertonicity.
    • Further research is needed to clarify the relationship between cricopharyngeal impression and dysphagia symptoms.
