Histopathological findings of extra-ileal manifestations at initial diagnosis of Crohn’s disease-related ileitis

Abstract

Crohn’s disease is a chronic inflammatory disorder that can affect any part of the gastrointestinal tract. Our objective was to review the histological findings in index biopsies from the terminal ileum and other gastro-intestinal tract sites of Crohn’s disease patients prior any treatment and to compare them with the findings from patients with non-specific ileitis. A total of 111 consecutive Crohn’s disease cases (55 females, median age 27 years) with extra-ileal biopsies were retrospectively selected. Upper gastrointestinal inflammatory changes were found in 68 % of gastric biopsies, 60 % of oesophageal biopsies and 43 % of duodenal biopsies with no significant difference in frequency bet..
