Colorectal manifestations of collagen vascular disease

Clinical manifestations are varied and complications include constipation, fecal incontinence, pseudoobstruction, perforation, hemorrhage, and mesenteric ischemia. Colorectal manifestations typically follow dermal presentations. Management should be conservative especially for pseudo-obstructions. Surgical intervention increases morbidity and should be chosen when absolutely necessary. Because of the high incidence of colorectal malignancies in patients with dermatomyositis, aggressive screening should be performed.
