Overview

Endoscopic ultrasound is required in cases where malignancy is suspected.

Endoscopic Ultrasound

Endoscopic ultrasound (EUS) is indicated in cases of achalasia with strong suspicion of malignancy. The presence of the following risk factors raises suspicion for malignancy:[1]

  • Elderly patients
  • Short duration of dysphagia history
  • Significant weight loss
  • Unusually increased resistance to passage of endoscope through gastroesophageal junction

Unusual thickening of gastroesophageal junction, mass lesions or neoplastic infiltration revealed on EUS suggests diagnosis of pseudoachalasia instead of achalasia.[2]
