title: pH profile of esophagus in patients with inlet patch of heterotopic gastric mucosa after tetragastrin stimulation. An endoscopic approach.
abstract: In a series of 1771 endoscopic examinations from 1988 to 1990, we observed 62 cases (3.3%) of inlet patch of heterotopic gastric mucosa (IPHGM) in the upper esophagus. Ten of the IPHGM patients complained of throat discomfort or globus sensation, and these symptoms were relieved by histamine H2-antagonists, suggesting that these symptoms could be caused by acid secretion from IPHGM. Acidity under tetragastrin stimulation was measured in the esophagus and compared with the pool of gastric juice and saliva under direct vision by a newly devised endoscopic method. Congo red staining was also carried out after pH measurement. Significant pH reduction at IPHGM was observed in three cases, and black coloration with Congo red staining in the IPHGM was observed in four cases. These findings suggest that IPHGM is a mucosal change with latent acid secretion.
