Transmural Histological Scoring Systems in Crohn’s Disease: A Systematic Review With Assessment of Methodological Quality and Operating Properties

Background The relative proportion of inflammation and fibrosis in a stricture is highly relevant in defining the clinical approach for Crohn’s disease [CD] patients. Whereas transmural inflammation in CD can be accurately estimated by cross-sectional imaging, evaluating the extent and severity of fibrosis still requires surgical pathology of intestinal resection specimens. This study systematically reviewed all existing transmural...
