Giardia lamblia (GL) is one of the causes of diarrhoea. GL is a frequent parasite in our country. In the literature, endoscopic aspects of Giardia duodenitis are mentioned. Some authors tried even to make the diagnosis on endoscopic criteria.
Aim: The purpose of the study is to find the endoscopic and histopathology changes produced by giardiasis.
Methods: 214 patients entered this study and underwent upper digestive endoscopy. Duodenal and gastric multiple biopsies were taken. Biopsies were stained with hematoxylin-eosine for Helicobacter pylori and Giemsa for Giardia lamblia. CP-test was also performed for Helicobacter and duodenal aspirate for giardiasis.
Results: The results indicates a high incidence of endoscopic and histopathology duodenitis in patients with giardiasis. The whitish spots on the erythematous duodenitis (60, 46%) and concentric ex-ulcerations (4, 16%) might be considered specific. On histology samples all the cases presented duodenitis, the first degree duodenitis was the most common (76, 63%).
Conclusions: It is concluded that there are specific endoscopic and histopathology features of giardiasis.
