title: The changing pattern of upper gastrointestinal disorders by endoscopy: data of the last 40 years.
abstract: Objectives. We have investigated the changes in the incidence of various diagnoses that have been made in the endoscopy unit throughout the last 40 years. Methods. In this study, changes in the incidence of endoscopic diagnosis in upper gastrointestinal system between 1970 and 2010 were evaluated. Their diagnosis, age, and gender data were entered into the Excel software. Results. Of the 52816 cases who underwent esophagogastroduodenoscopy in the 40-year time period, the mean age was 48.17 ± 16.27 (mean ± SD). Although overall more than half of the patients were male (54.3%), in 1995 and after a marked increase was seen in the proportion of female gender (51-55%). The presence of hiatal hernia, reflux esophagitis, and the number of Barrett's esophaguses significantly increased. Erosive gastritis showed gradual increase, while the number of gastric ulcers decreased significantly. The presence of gastric and esophageal cancer significantly decreased. The number of duodenal ulcers significantly decreased. Conclusion. We detected that the incidences of esophagitis, Barrett's esophagus, and erosive gastritis significantly increased while the incidences of gastric/duodenal ulcer and gastric/esophageal cancer decreased throughout the last 40 years.
