Intestinal metaplasia of the gastric cardia: findings in patients with versus without Barrett’s esophagus

There is controversy about finding intestinal metaplasia (IM) of the gastric cardia on biopsy. The most recent American GI society guideline comments that IM cardia is not more common in patients with Barrett's. It provides limited guidance on whether the cardia should be treated when patients with Barrett's undergo endoscopic eradication therapy (EET) and whether the cardia should be biopsied after ablation. The aims of our study were to determine the frequency in the proximal stomach of (1) histologic gastric cardia mucosa and (2) IM cardia.
