Description
Summary:The term “short bowel syndrome (SBS)” defines “the clinical feature associated with a remaining small bowel in continuity of less than 200 cm from the ligament of Treitz” and is characterized by malabsorption, diarrhea, fatty stools, malnutrition, and dehydration. SBS is the primary pathophysiological mechanism of chronic intestinal failure (CIF), defined as the “reduction of gut function below the minimum necessary for the absorption of macronutrients and/or water and electrolytes, such that intravenous supplementation (IVS) is required to maintain health and/or growth” in a metabolically stable patient. By contrast, the reduction of gut absorptive function that does not require IVS has been termed “intestinal insufficiency or deficiency” (II/ID). The classification of SBS can be categorized as follows: anatomical (anatomy and length of the residual bowel), evolutional (early, rehabilitative, and maintenance phases), pathophysiological (SBS with or without a colon in continuity), clinical (with II/ID or CIF), and severity of CIF (type and volume of the required IVS). Appropriate and homogeneous patient categorization is the mainstay of facilitating communication in clinical practice and in research.
