What symptom is colonic wall thickening?

First, there are many reasons for the edema and thickening of the intestinal wall. Here we will introduce that 57% of patients with scleroderma are affected by the small intestine. The pathological changes of the small intestine include smooth muscle atrophy, patchy collagen deposition in the submucosa, muscle layer and serosa layer, and chronic inflammatory cell infiltration in the lamina propria.

Second, in dermatomyositis, the small intestine has different degrees of expansion and segmental changes, with low motility and prolonged transit time. The edema and thickening of intestinal wall could be seen by naked eyes. Microscopic examination showed multiple mucosal erosion, submucosal edema, muscular atrophy and fibrosis with lymph and plasma cell infiltration. The intimal thickening of small arteries and veins from submucosa to serosa is prone to thrombosis and lumen occlusion.

Third: polyarteritis nodosus can affect any part of the intestinal tract, but the main invasion of mesenteric arteries, small arteries and submucosal and muscular layer, followed by small veins. The lesions were segmental, and all layers of the wall were involved. The histological features were fibrinoid degeneration, necrosis and thrombosis with inflammatory cell infiltration.
