Short bowel syndrome-associated intestinal failure: diagnosis and prognosis

Short bowel syndrome in adults is a clinical malabsorptive syndrome associated with having <200 cm of residual small bowel in continuity, measured from the duodenojejunal flexure. Intestinal failure is the reduction of gut function below the minimum required for the absorption of macronutrients and/or water and electrolytes, thereby requiring parenteral support to maintain health and/or growth. The remaining small bowel length and segment, and health of the remnant bowel have important prognostic implications. Care gaps exist regarding the diagnosis and management of this condition and future efforts should address these disparities in order to provide optimal care to these patients.
