Endoscopic versus histological diagnosis of Barrett's esophagus: a cross-sectional survey.
    Polish journal of pathology : official journal of the Polish Society of Pathologists, 2011, Volume: 62, Issue:3

    Barrett's esophagus is a common pathological condition in patients with gastro-esophageal reflux disease.. The aim of this study was to compare endoscopic diagnosis versus histological confirmation.. Cross-sectional.. Cancer Institute of the Imam Khomeini Hospital.. A total of 50 patients with a history of gastro-esophageal reflux were recruited and underwent upper endoscopy at this cross-sectional survey. Four-quadrant biopsy was taken from all suspected areas of intestinal metaplasia. Sections of blocks were stained with Mixed Alcian Blue (PH 2.5)/PAS and haematoxylin-eosin stainings for the diagnosis of intestinal metaplasia (complete vs. incomplete types) and goblet cell / columnar cell / dysplasia, respectively.. The presence of Helicobacter pylori was assessed by Giemsa staining.. There were 44 cases of short-segment Barrett's esophagus and 6 of long-segment Barretts esophagus by endoscopy. When examined by histologic examination, 12 patients with short-segment Barrett's esophagus and 4 with long-segment Barrett's esophagus had intestinal metaplasia. Haematoxylin-eosin staining diagnosed 12 cases of intestinal metaplasia, whereas mixed alcian blue/PAS was used to diagnose 16 cases (κ = 80%, p < 0.001). The positive predictive value in the diagnosis of goblet cell metaplasia and columnar cell metaplasia was 32% and 66%, respectively. Helicobacter pylori infection was observed in 10 cases of those with columnar cell metaplasia without goblet cells, while none of the patients with intestinal metaplasia were infected.. Our findings suggest that biopsy taking is necessary in all patients with gastro-esophageal reflux disease, whose results suggest columnar cell lining in distal esophagus in endoscopy.

Point prevalence of peptic ulcer and gastric histology in healthy Indians with Helicobacter pylori infection.
    The American journal of gastroenterology, 1997, Volume: 92, Issue:9

    To study the prevalence of peptic ulcer and the histological appearance of the gastric mucosa in healthy, asymptomatic Indians infected with Helicobacter pylori.. Asymptomatic, healthy individuals without any GI symptoms were invited to undergo endoscopy of the upper GI tract. A careful search was made for any erosion or ulcer. Four biopsy specimens were obtained from the gastric corpus and antrum. Histological sections were stained with hematoxylin and eosin for histological details and with Loffler's methylene blue for the presence of H. pylori. Alcian blue periodic acid-Schiff stain (pH 2.5) was used to classify and grade areas of intestinal metaplasia.. Histological examination showed chronic gastritis in 72 (80%) persons. Pangastritis was seen in 22% of subjects; pangastritis with antral predominance, in 28%; and antrum-only gastritis, in 50%. Activity was noted in biopsy specimens from only 33% of the subjects. H. pylori infection was present in 70 (78%) subjects. All of these subjects had evidence of chronic gastritis. Endoscopic examination revealed a normal appearance in 88 individuals. In two individuals a duodenal ulcer was seen. Both subjects had severe H. pylori infection in the antral mucosa. Of the 70 persons having H. pylori infection, only two (2.8%) had a duodenal ulcer.. This study showed that despite a high prevalence of H. pylori infection in asymptomatic, healthy Indians, the point prevalence of peptic ulcer is low, and chronic active gastritis is uncommon.
