Heung Bae Kim and Tom Jaksic at Children's Hospital Boston. The STEP procedure is designed for patients with short bowel syndrome who are dependent on intravenous (IV) nutrition because they cannot tolerate full use of their gastrointestinal tract. The goal of the STEP procedure is to increase the length of the small intestine so that patients can better tolerate nutrition through the gastrointestinal tract and eventually wean from IV nutrition.
