Abstract
A condition known as diversion colitis frequently develops in segments of the colorectum after surgical diversion of the fecal stream; it persists indefinitely unless the excluded segment is reanastomosed. The disease is characterized by bleeding from inflamed colonic mucosa that mimics the bleeding of idiopathic inflammatory bowel disease, and it may culminate in stricture formation. We hypothesized that this condition is caused by the absence of luminal short-chain fatty acids, the preferred metabolic substrates of colonic epithelium.
