[Comparative evaluation of some morphologic methods for detecting Helicobacter pylori in gastric mucosa].

Gastroscopic examination was performed in 183 patients with upper gastrointestinal symptoms, with brush biopsy and taking of mucosa specimens for cytological and histopathological examination in order to detect the presence of Helicobacter pylori. Greater effectiveness of brush biopsy was demonstrated in comparison to histological examination of tissue fragments and significantly higher effectiveness of staining using the Giemsa-May-Grunwald method was shown in comparison to staining with hematoxylin and eosin.
