Background And Aims:
The question of whether an endoscopically normal-appearing esophagogastric junction should be biopsied in patients with gastroesophageal reflux disease is controversial. We have addressed this issue using endoscopy and histopathology.
Methods:
A total of 114 consecutive patients (58 males) with symptoms of gastroesophageal reflux disease prospectively underwent endoscopy, including biopsy sampling from the esophagogastric junction. Endoscopically visible columnar-lined esophagus was defined by the presence of gastric-type mucosa above the level of the rise of the gastric folds. Histopathology was conducted using the Paull-Chandrasoma classification.
Results:
Of the 114 patients, 85 (74.6%) had endoscopically visible columnar-lined esophagus of length < or =0.5 cm (n = 82), 1 cm (n = 2) and 7 cm (n = 1); 29 patients (25.4%) had a normal endoscopic junction. All patients had histopathologic columnar-lined esophagus. Intestinal metaplasia and low-grade dysplasia was identified in 26 (22.8%) and 5 (4.4%) individuals, respectively, and was not statistically different in endoscopically normal vs. abnormal junction (P = 0.408 for intestinal metaplasia, P = 0.775 for low grade dysplasia). Intestinal metaplasia was independent from endoscopic esophagitis (P = 0.398) and hiatal hernia (P = 0.405).
Conclusions:
Columnar-lined esophagus cannot be excluded by endoscopy. In patients with gastroesophageal reflux disease, biopsy sampling of normal-appearing junction is recommended for histopathologic exclusion of intestinal metaplasia and low-grade dysplasia.
