Barrett’s esophagus: Prevalence and risk factors in patients with chronic GERD in Upper Egypt

Figure 1 Endoscopic findings. Esophagitis was detected in 498 patients (49.8%) and NERD was seen in 502 patients. BE was present in 73 patients. EAC was detected in eight patients.

Figure 2 Distal esophageal acid exposure in both groups. A: In the supine position. The median time at pH < 4 in the distal esophagus in the supine position was significantly longer in patients with BE (group A) than in those with GERD without BE (group B) (P < 0.03); B: In the upright position. The median time at pH < 4 in the distal esophagus in the upright position did not differ significantly between patients with BE (group A) and those with GERD without BE (group B).

Figure 3 BE without dysplasia, showing true barrel-shaped goblet cells and intervening columnar cells, with incomplete brush-border, intestinal type metaplasia. The squamous epithelium of the normal esophagus was transformed into columnar epithelium (HE, × 200).
