Area of Science:

  • Gastroenterology
  • Oncology
  • Neurology

Background:

  • Secondary achalasia can be caused by malignancy, mimicking primary esophageal motility disorders.
  • Differentiating secondary achalasia from primary achalasia is crucial for appropriate patient management.

Observation:

  • A 74-year-old male patient with stage III lung adenocarcinoma presented with symptoms suggestive of secondary achalasia.
  • The patient exhibited clinical improvement following intrasphincteric injections of botulinum toxin type A.

Findings:

  • Botulinum toxin type A injections demonstrated efficacy in managing malignancy-induced secondary achalasia.
  • This case underscores the potential role of botulinum toxin in treating pseudoachalasia secondary to lung cancer.

Implications:

  • Botulinum toxin may offer a minimally invasive treatment option for secondary achalasia.
  • Diagnostic strategies are essential to distinguish malignancy-related achalasia from the primary condition.
