title: Living-related intestinal transplantation: first report of a standardized surgical technique.
abstract: BACKGROUND
  Intestinal transplants using cadaver donors have become an alternative to total parenteral nutrition (TPN) for the treatment of irreversible intestinal failure. Intestinal transplants using living-related donors have rarely been attempted, and the surgical technique has not been standardized.
  
  
  METHODS
  We performed a living-related intestinal transplant for a paraplegic, 16-year-old boy with life-threatening TPN complications, including lack of vascular access, recurrent line infections, and intermittent liver dysfunction.
  
  
  RESULTS
  A four antigen-matched donor (father) underwent resection of 200 cm of the ileum on a vascular pedicle comprising the ileocolic artery and vein. This resection left the donor with 300 cm of proximal small bowel, 20 cm of the most distal terminal ileum, the ileocecal valve, and all of the large intestine. The donor's ileocolic artery and vein were anastomosed to the recipient's infrarenal aorta and cava; bowel continuity was restored with an end-to-end anastomosis between the recipient's jejunum and the donor's ileum. Both donor and recipient had uneventful postoperative courses. Recipient maintenance immunosuppression has been with tacrolimus, mycophenolate mofetil, and prednisone. One year after transplant, urine methylmalonic acid indicates good vitamin B12 absorption in both the donor and recipient. The recipient has been completely off TPN since discharge (posttransplant day 21), has gained 20 kg, and has had no evidence of rejection, infection, or graft-versus-host disease.
  
  
  CONCLUSIONS
  Intestinal transplants from living-related donors can be lifesaving for selected patients with chronic intestinal failure and can be done with minimal risk to the donor.
