One hundred twenty one cases of oesophagitis by gastroesophageal reflux were observed through a retrospective study of 1250 endoscopies of the upper digestive tract. The oesophagitis was staged according to Savary-Miller classification. The prevalence (93.3%) of cases were in I and II stage. The Authors found that the most frequent associated diseases with oesophagitis by gastroesophageal reflux were: hiatal hernia, gastric and duodenal peptic disorders, gastric resection according Billroth II and biliary disorders. In 86.7% of cases, endoscopic diagnosis was confirmed by histological findings. From these data and from those reported in literature the authors can ascertain that endoscopy, associated with histological findings has an important role in diagnosing oesophagitis and in monitoring medical and surgical treatment used.
