Abstract

CSENDES J, Attila et al. Clinical and laboratory features of patients with chronic gastroesophageal reflux. Rev. méd. Chile [online]. 1998, vol.126, n.7, pp.769-780. ISSN 0034-9887.  http://dx.doi.org/10.4067/S0034-98871998000700004.

Background: Sixty percent of adults has typical symptoms of gastroesophageal reflux in Chile. Aim: To report the clinical and laboratory features of patients with gastroesophageal reflux. Patients and methods: Five hundred thirty four patients (255 male) with gastroesophageal reflux were included in a prospective protocol that included clinical analysis, manometry and endoscopy in all patients, barium swallow in 427, scintigraphy in 195, acid reflux test in 359, 24 h pH in 175, and differential potential of gastroesophageal mucosa in 73 patients. Results: There was no correlation between the severity of symptoms and the endoscopical severity. Patients with Barret esophagus were 12 years older, were male in a greater proportion and had a higher proportion of manometrically incompetent sphincters than patients with esophageal reflux but without esophagitis or with erosive esophagitis. Severity of acid reflux, measured with 24 h pH monitoring was proportional to the endoscopical damage of the mucosa. There was a close relationship between the mucosal change limit determined with differential potentials and with endoscopy. No short esophagi were found. Conclusions: Patients with symptoms of gastroesophageal reflux must be assessed using several objective measures to determine the severity of their pathological alterations.
