Abstract

Gastric cardia inflammation and intestinal metaplasia are the subjects of recent investigation. Some authors have found associations with gastroesophageal reflux disease, whereas others have identified relationships with Helicobacter pylori (HP). We studied 150 consecutive patients who underwent upper endoscopy, had normal gastroesophageal anatomy, and had biopsies of the antrum, cardia, and lower esophagus, to evaluate relationships between reflux esophagitis, cardia inflammation, intestinal metaplasia, and HP gastritis. Forty-two patients had HP infection. Cardia inflammation was significantly related to esophageal squamous inflammation in the non-HP-infected patient group and to antral inflammation and cardia HP infection in the HP-infected patient group. The differences between the patient groups was most apparent in the patients with moderate or marked inflammation. Twenty-seven percent of patients had cardia intestinal metaplasia that was related to cardia inflammation. Cardia inflammation and intestinal metaplasia probably have multiple causes. Pathologists should refrain from applying the term Barrett's esophagus for biopsies procured from the cardia that show intestinal metaplasia in patients with a normal squamocolumnar junction.
