Area of Science:

  • Gastroenterology
  • Histopathology
  • Oncology

Background:

  • Barrett's esophagus diagnosis has evolved, now emphasizing specialized columnar epithelium (SEC) with goblet cells.
  • Previous definitions were broader, including gastric or intestinal metaplasia.
  • Understanding SEC prevalence is crucial for accurate diagnosis and risk assessment.

Purpose of the Study:

  • To determine the frequency of specialized columnar epithelium (SEC) in the Indian population.
  • To evaluate the incidence of Barrett's esophagus based on the updated definition.
  • To assess the diagnostic yield of esophageal biopsies in dyspeptic patients.

Main Methods:

  • 150 patients with dyspepsia underwent esophagogastroduodenoscopy and esophageal biopsy.
  • Histological examination included routine Hematoxylin and Eosin (H&E) staining.
  • Specialized staining with Alcian blue-PAS was performed to identify goblet cells.

Main Results:

  • Esophagitis was observed in 50% (75/150) of cases.
  • Columnar epithelium of gastric type was present in 42% (63/150) of cases.
  • Only 2.6% (4/150) of cases exhibited specialized columnar epithelium (SEC), meeting the criteria for Barrett's esophagus.

Conclusions:

  • The incidence of Barrett's esophagus, defined by SEC with goblet cells, is low (2.6%) in the studied Indian population.
  • The updated definition significantly impacts the diagnosed prevalence of Barrett's esophagus.
  • Esophageal biopsies are essential for accurate histological classification in dyspeptic patients.
