SUMMARY Intestinal parasitic infections are common worldwide with higher prevalence in developing countries especially in Africa due to warm climate and low hygiene standards. Moreover, prevalence of parasitic diseases also increased now in developed countries due to immigration and increased frequency of AIDS and other immune-compromising conditions. The prevalence of enteric parasites is underestimated due to lack of adequate surveillance systems in developing countries as well as lack of available sensitive diagnostic techniques for detection of intestinal parasites. Microscopic examination of stool for detection of ova and parasites is still the traditional method for diagnosis in developing countries and many developed countries. However, it is time-consuming, requires a high level of skills and lacks sensitivity and specificit Examination of duodenal content and histopathological examination of duodenal mucosa is useful for the detection of intestinal and biliary tree parasites. Many reports of parasites diagnosed during routine upper endoscopy and many diseases like anemia caused by helminthic infection were diagnosed by upper endoscopy. The aim of the present work was to assess the prevalence of intestinal parasitic infections among patients admitted for upper gastrointestinal endoscopy at Endoscopy Unit of Tanta Universit
