Abstract: | OBJECTIVE: To compare the frequency of intestinal metaplasia (IM) in patients with portal hypertensive gastropathy (PHG) to the control group with functional dyspepsia. METHODS: Two-hundred and eighty-nine cases were prospectively evaluated in three groups (controls:group I--123 patients; cirrhotics: group II--135 patients; noncirrhotic portal hypertensives: group III--31 patients). Mucosal biopsies (three antrum, one angulus, two corpus) were taken and examined for atrophy, IM, dysplasia, Helicobacter pylori (Hp) and histologic PHG. RESULTS: Frequencies of IM in groups I, II and III were 17.1% (type I, 3.3%; type II, 10.6%; type III, 3.3%), 34.3% (type I, 9.6%; type II, 17%; type III, 6.7%) and 33.3% (type I, 9.7%; type II, 12.9%; type III, 9.7%), respectively. In patients with PHG, frequency of IM was significantly higher than in control group (P<0.05) and correlated with the severity of PHG (P<0.05). The frequency of type III IM was not statistically different among the three groups. Frequency of atrophy in cirrhotic patients was higher than in control group (17.9% in group I, 32.6% in group II, 25.8% in group III; P<0.05). In the control group, Hp prevalence was significantly higher than in patients with PHG (P<0.05) and there was a positive correlation between Hp and atrophy (P<0.05). In multivariate analysis, PHG and age were found as independent predictors for IM; PHG, age and Hp for atrophy. CONCLUSION: Frequencies of atrophy and IM are higher in patients with PHG. PHG is a reliable marker for IM and atrophy in gastric mucosa. |
