[Comparative evaluation of efficacy of histological and cytological methods of H. pylori primary diagnosis in pyloroduodenal ulcer complicated by hemorrhage].

In 48 patients, suffering gastroduodenal ulcer disease, complicated by hemorrhage, cytological and histological investigations were conducted to reveal helicobacter infection. There was established, that sensitivity, specificity and accuracy of smears--the gastric mucosa imprints--cytological investigation exceeds such of histological investigation of biopsies. In more than 80% patients, in whom pyloroduodenal ulcer, complicated by hemorrhage, was diagnosed, Helicobacter pylori (H. pylori) was revealed in gastric mucosa.
