[Progression of pathogenesis, diagnosis and treatment of diversion colitis]

Diversion colitis (DC) is a common non-specific inflammation of the malfunctioning bowel segment after diversion of feces. Although most patients develop DC during stoma, there are no obvious clinical symptoms, and a small number of patients show abdominal pain, mucus discharge and hematochezia. The erythema, diffuse particles and vascular texture blur are the most prominent endoscopic manifestations, and the lymphatic follicular hyperplasia is the most prominent pathological manifestations.Reconstruction of intestinal continuity is the best way to cure recanted colitis. In this review, we summarize and review the mechanism of occurrence, clinical features, diagnosis and treatment of DC, which will be helpful for the effective control and prevention of DC.
