Gastric secretion of acid and pepsin in patients with esophageal stricture and appropriate controls.
Most cases of esophageal stricture are associated with acid/peptic reflux esophagitis. While patients with strictures commonly have disordered lower esophageal sphincters and poor clearance and neutralization mechanisms, it is not known whether they also have abnormal gastric secretion. This study examined fasting, basal, and stimulated acid and pepsin secretion. With an endoscopic diagnosis of esophagitis, patients with stricture (< 12.5 mm) were matched for age, sex, concurrent gastrointestinal disease (duodenal ulcer, N = 9), Zollinger-Ellison syndrome (N = 6), and postgastric surgery state (N = 5), as well as the absence of ulcer disease (non-DU, N = 37). Fasting, basal, and pentagastrin-stimulated acid and pepsin secretion were measured. Overall, the 57 stricture patients had the same acid and pepsin secretion as their matched controls with esophagitis; the same was true for each of the subgroups (ZES, DU, non-DU, and postsurgical). Stricture patients weighed less and had a lower body mass index (P < 0.01). Patients with esophageal peptic stricture have the same acid and pepsin output as control patients matched for sex, age, background gastrointestinal disease, and the presence of esophagitis.
