The Cleveland Clinic institutional guidelines for the management of intestinal failure, including long-term or home parenteral nutrition and related complications, intestinal rehabilitation, and small bowel transplantation, were reviewed. PubMed was searched for relevant articles. The search was performed in November 2008; keywords used were home parenteral nutrition, short bowel syndrome, intestinal rehabilitation, and small-bowel transplantation. Randomized, prospective, observational, retrospective reviews and case report articles that contained relevant data for long-term parenteral nutrition, intestinal rehabilitation, and intestinal transplantation were selected. Researchers reviewed 67 selected articles that met our inclusion criteria. Our institution data registries for intestinal rehabilitation and home parenteral nutrition were also reviewed for relevant data. The survival of tens of thousands of children and adults with complicated gastrointestinal problems has been possible because of parenteral nutrition. In selected patients, a program of intestinal rehabilitation may avoid the need for long-term parenteral nutrition.
