[Results of an intestinal transplantation program in Spain. Five years later]

More than two thirds of all intestinal transplantations (ITx) performed around the world correspondent to recipients younger than 18.

To analyze our 5-year experience in pediatric ITx.

We assessed the outcome of the 19 children included in list out of 41 patients considered for ITx from 1997. The main cause of intestinal failure was short bowel syndrome (14) followed by intestinal motility disorders (3) and congenit disorders of intestinal epithelium (CDIE) (2). The median of age, at the moment of including in the list, was 0.9 years (range 0.4-17) and median of weight was 6.4kg (range 0.4-29.3). Ten children were included for liver and small bowel transplantation (LSBTx), 7 to isolated small bowel (SBTx), and 2 for multivisceral transplantation (MVTx). Indications for SBx were hepatic fibrosis/cirrhosis (10), hepatic fibrosis in evolution (5) (to avoid later LSBTx), intractable diarrhoea (1), recurrent line infections (1), lost of central vein access (1), and bad quality of life in one.

Five children died in the waiting list, after a median time of 325 days (range 19-581). Seven remain in the waiting list (median 139 days, range 30-778). In 3 of these the indication changed from SBTx to LSBTx because of progression to end stage liver disease. Six children recieved seven grafts (1 MVTx, 4 LSBTx, 2 SBx) after a median time in the waiting list of 352 days (range 66-732). Six out of seven grafts achieved normal function and all survivals reached full digestive autonomy after Tx. We had to rejection episodes, one with good response to medical treatment and one that required removal of intestinal allograft and later LSBTx. Two children died 1 because of problem not related to the procedure (hemorrage following liver biopsy) and one girl died 29 months after transplant due to post-transplantation lymphoproliferative disease.

ITx is a realistic alternative in our country for children with intestinal failure. The main problems are immunologic (rejection, lynphoproliferative and disease) Shortage of small weight donors is a dramatic limitation that prompts the discussion of surgical alternatives.
