title: The changing pattern of upper gastro-intestinal lesions in southern Saudi Arabia: an endoscopic study.
abstract: OBJECTIVE
  Dyspepsia is a common gastrointestinal disorder and is the most common indication for upper gastrointestinal endoscopy (UGIE). In recent years, it has been observed in several centers that there is a change in the causes of dyspepsia as revealed by UGIE. Our main objectives were: (1) To study the pattern of upper gastrointestinal pathology in patients with dyspepsia undergoing upper endoscopy; (2) Compare that with the pattern seen 10-15 years earlier in different areas of KSA.
  
  
  METHODS
  Retrospective study of all UGI endoscopies performed at Aseer Central Hospital, Abha, Southern Saudi Arabia during the years 2005-2007 on patients above 13 years of age. Patients who underwent UGIE for reasons other than dyspepsia were excluded. The analysis was performed using the SPSS 14 statistical package.
  
  
  RESULTS
  A total of 1,607 patients underwent UGI endoscopy during the three-year study period (age range, 15-100). There were 907 males (56.4%) and 700 female (43.6%). Normal findings were reported on 215 patients (14%) and the majority had gastritis (676 = 42%), of whom 344 had gastritis with ulcer disease. Moreover, 242 patients (15%) had gastro-esophageal reflux (GERD), with or without esophagitis or hiatus hernia. Also, a total of 243 patients had duodenal ulcer (DU) (15%) while only 12 had gastric ulcer (0.7%).
  
  
  CONCLUSIONS
  There is clear change in the frequency of UGIE lesions detected recently compared to a decade ago with an increasing prevalence of reflux esophagitis and hiatus hernia. This could be attributed to changes in lifestyle and dietary habits such as more consumption of fat and fast food, increased prevalence of obesity, and smoking. These problems should be addressed in order to minimize the serious complications of esophageal diseases.
