Identification of Patients with Colon Ischemia in the Swedish ESPRESSO Cohort: A Validation Study

Background

Colon ischemia is the most common form of intestinal ischemia, yet case identification in epidemiological research remains challenging due to heterogeneous diagnostic criteria and absence of a specific International Classification of Diseases (ICD) code. The use of SNOMED (Systematized Nomenclature of Medicine) for gastrointestinal biopsies and surgical specimens enables a unique possibility to identify colon ischemia cases.
