Portal Hypertensive Gastropathy in Liver Cirrhosis: Prevalence, Natural History, and Risk Factors.

Abstract

Objective Portal hypertensive gastropathy (PHG) is a common finding in patients with liver cirrhosis (LC) and may cause both acute and chronic bleeding. A number of risk factors for PHG have been identified. The present study explored the characteristics of Japanese patients with LC who develop PHG.MethodsClinical findings (age, sex, etiology, the presence of esophageal varices, splenomegaly and severity of LC), laboratory data, and whether or not atrophic gastritis was found on endoscopy were retrospectively reviewed in patients with LC who had undergone esophagogastroduodenoscopy. PHG was endoscopically graded as absent, mild, or severe.ResultsOf 262 patients with LC (mean age, 69 years old; 145 men), 158 had no PHG, 41 had mild PHG, and 63 had severe PHG. In a univariate analysis, a younger age, male sex, non-viral etiology, absence of atrophic gastritis, presence of esophageal varices, splenomegaly, severe LC, low platelet count, and low hemoglobin concentration were associated with PHG. A multivariate analysis showed a significant association of PHG with the absence of atrophic gastritis (p<0.048), presence of esophageal varices (p<0.001), non-viral etiology (p<0.033), splenomegaly (p<0.048), and severe LC (p<0.005). There were no cases of massive bleeding from PHG during follow-up.ConclusionEsophageal varices, splenomegaly, severe liver cirrhosis, the absence of atrophic gastritis, and etiology were found to be risk factors for PHG in Japanese patients.
