Enteritis toxin accumulation. Ischemic enteritis is uncommon compared to ischemic colitis due to the highly vascularised nature of the small intestine, allowing for sufficient blood flow in most situations. It develops due to circulatory shock of mesenteric vessels in the absence of major vessel occlusion, often associated with an underlying condition such as hypertension, arrhythmia or diabetes. Thus it has been considered to be associated with atherosclerosis. Surgical treatment is usually required due to the likelihood of stenosis or complete occlusion of the small intestine. Ischemic damage can range from mucosal infarction, which is limited only to the mucosa; mural infarction
Inflammation the lysosomal elimination of the infective agent. Specific patterns of acute and chronic inflammation are seen during particular situations that arise in the body, such as when inflammation occurs on an epithelial surface, or pyogenic bacteria are involved. Inflammatory abnormalities are a large group of disorders that underlie a vast variety of human diseases. The immune system is often involved with inflammatory disorders, demonstrated in both allergic reactions and some myopathies, with many immune system disorders resulting in abnormal inflammation. Non-immune diseases with causal origins in inflammatory processes include cancer, atherosclerosis, and ischemic heart disease. Examples of disorders associated with
