Upper GI endoscopy was performed in 50 adult patients attending the gastroenterology OPD with gastroduodenal diseases. Gastric antral mucosal brushings were taken for cytological evaluation and urea broth test followed by antral biopsy. The slides prepared were stained with Wright Giemsa (WG), Hema toxylin & Eosin (H&E) and Papanicolaou (Pap). Brush Cytology Smears were compared with biopsy sections for detection of Helicobacter pylori and the staining techniques were evaluated to see which stain was easiest to perform and interpret on routine basis. H&E stained sections were examined for histomorphological parameters associated with H. pylori infection. Brush cytology was rapid and simple with observed sensitivity of 90% and specificity of 100%. On evaluating the various stains, M.B. and W.G. were found to the rapid and easy to perform and the bacteria stood out very well against the background. Of the histomorphological parameters studied, presence of actively and lymphoid aggregates and absence of intestinal metaplasia correlated positively with the presence of the bacteria. Cytological brushing urea broth test was not very sensitive (55.2%) and specific (51%) for detection of the bacteria.
