Rigid endoscopy for globus sensation rarely reveals serious conditions like cancer. This study suggests the procedure may be unnecessary, avoiding risks and costs for most patients.

Area of Science:

  • Otolaryngology
  • Gastroenterology

Background:

  • Globus sensation, a common complaint, prompts investigations into potential underlying causes.
  • The diagnostic yield of rigid endoscopy for globus symptoms requires evaluation.

Purpose of the Study:

  • To assess the diagnostic value of rigid endoscopy in patients presenting with globus symptoms.
  • To determine the prevalence of significant pathological findings in this patient group.

Main Methods:

  • Retrospective analysis of 250 patients undergoing rigid endoscopy for globus symptoms over 12 months.
  • Statistical analysis, including chi-square test, to correlate clinical diagnosis with endoscopic findings.

Main Results:

  • A high rate (86.8%) of normal findings in the larynx, pharynx, and upper esophagus.

  • Abnormal findings were infrequent, including cricopharyngeal spasm (4.8%), reflux (4.4%), and other minor conditions.
  • The 95% confidence interval for malignancy was low (0-3.7 per 1000), with a highly significant p-value (0.0001) for the relationship between diagnosis and findings.

    • Conclusions:

    • Rigid endoscopy for globus sensation is unlikely to identify neoplastic lesions.
    • The investigation may be inappropriate for most patients with globus symptoms, given the low diagnostic yield.
    • Avoiding rigid endoscopy can prevent associated risks, costs, and patient discomfort.
