Small bowel transplantation.

Abstract

Small bowel transplantation has become the treatment of choice for patients with chronic gut failure whose illness cannot be maintained on home parenteral nutrition. Outcomes have improved as a result of refinements in patient selection, surgical techniques, and the prevention, diagnosis, and treatment of graft rejection. Early listing is important because of the shortage of organ donors. Rejection rates are still 50% or more, despite the use of potent immune suppression. Sepsis rates are also higher for patients who have had small bowel transplantation than for those who have received other organs because of bacterial translocation from the gut secondary to preservation injury and graft rejection. Graft and patient survival rates after small bowel transplantation are comparable to rates after lung transplantation. Successful transplant recipients resume unrestricted oral diets.
