title: [Giardia lamblia and duodenal involvement].
abstract: 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.
  
  
  OBJECTIVE
  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.
