Endoscopic and histologic findings in Iranian patients with heartburn

Abstract

Background : Heartburn is a common manifestation of gastroesophageal reflux disease. Barrett's esophagus and esophageal adenocarcinoma, known complications of this disease, appear to be less prevalent in Asia than in Western countries . We looked for endoscopic and histologic evidence of Barrett's esophagus in Iranian patients with heartburn. Methods: During September 2001 to September 2003, endoscopy was done in all patients with heartburn, either lasting longer than 3 months (n=1182) or for 1-3 months but resistant to 4 weeks of omeprazole therapy (n=66). Biopsy was taken from columnar-lined mucosa above the GE junction, at 5 cm above the Z line in normal-appearing mucosa, and from any abnormal areas. Results: Of the 1248 patients (mean age 45 [SD 15.5] years, 750 men; duration of heartburn 68 [SD 87.5] months), 960 (66.5%) had erosive esophagitis and 30 (2.4%) had Barrett's esophagus, including 10 and 20 with long- and short-segment involvement, respectively. Of 134 patients with normal-appearing mucosa, 122 had histologic evidence of esophagitis. Conclusion: Barrett's esophagus may be less common in Iran than in Western countries, despite presence of severe heartburn and erosive esophagitis © 2004 Indian Journal of Gastroenterology.
