Our main objective has been to study the prevalence of oesophagitis by upper digestive endoscopy. Within 12 months, we have registered 228 cases of oesophagitis out of 612 oesophagean anomalies (37.25%) during 3019 fibroscopies. Oesophagitis has been found to 63.59% in cases in young adult men. Peptic oesophagitis has been most frequent and its congestive aspects most current. The main indication of endoscopy in patients suffering of oesophagitis has been epigastralgies.
