Answer

Diversion colitis is an inflammatory process that occurs in segments of bowel that have been "diverted" from the fecal stream (ie, after ileostomy or colostomy). It is thought to result from lack of exposure of colonocytes in the diverted segment to short-chain fatty acids. Most cases of diversion colitis are asymptomatic and do not require long-term monitoring. Diversion colitis is not associated with an increased risk for cancer. In symptomatic cases, the restoration of intestinal continuity is generally curative.
