Gastroesophageal reflux disease: clinical, endoscopic, and intraluminal esophageal pH monitoring evaluation.
One hundred and twenty-two patients with gastroesophageal reflux disease were studied (90 with and 32 without esophagitis) with the objective of analyzing possible differences between those with and without esophagitis. Evaluation consisted of clinical interview, endoscopy of the high digestive tract, esophageal manometry, and pH monitoring. There was no significant difference between the groups in age, sex, or symptoms. The incidence of hiatal hernia was greater in the group with esophagitis. Although the frequency of motor changes was similar, the type of anomaly was different. The reflux pattern was very similar in both groups. Therefore, the concept of reflux disease, esophagitis, and pathological reflux still needs a broader definition for greater diagnostic precision and for comparing the results of different studies on the subject. Normal reflux (confirmed using pH esophageal monitoring) in 12.2% of patients with esophagitis suggests that other factors are implicated in the etiology of the disease besides those measured using this examination.
