The aim of this study was to assess whether the taking of an additional biopsy from the incisura angularis increases the chance of detecting maximal degrees of atrophy and intestinal metaplasia (IM) in patients with Helicobacter pylori gastritis and functional dyspepsia. At entry into a randomised trial, biopsies were taken from 328 patients (mean age 48 years), two from both the gastric antrum and corpus, and one from the incisura angularis, and comparative grading of gastritis variables was carried out. Biopsy material from the gastric antrum, corpus, and the incisura angularis revealed no notable differences in atrophy or an incidence of IM and mucosa-associated lymphatic tissue. However, when the incisura biopsies were classified histologically, 58% contained antral mucosa (AM), 18% corpus mucosa (CM), and 24% intermediate zone mucosa. AM at the incisura was associated with considerably more severe gastritis in both the incisura and antrum (14% atrophy, 20% IM) than in CM of incisura (2% atrophy, 6% IM). Corpus atrophy and IM were rare in the AM group and absent from the CM group. Incisura angularis biopsy in patients with H. pylori gastritis and functional dyspepsia does give additional information regarding the severity of gastritis expected in the corpus and antrum. Antral-type mucosa in the incisura angularis region seems to indicate an increased risk for the development of atrophy and/or IM. (c) 2006 Elsevier GmbH. All rights reserved.
