Pediatric small bowel transplantation.

PURPOSE OF REVIEW

Intestine has become a transplantable organ due to the improvement in immunosuppressive drugs. The early referral to a reference unit is crucial in prognosis. There are still some pending issues like chronic rejection, the knowledge of the role of DSA development or early noninvasive detection of acute rejection.

RECENT FINDINGS

The appearance of tacrolimus and mTOR, and the use of induction therapy have marked a turning point with better graft and patient survival rates. The inclusion of the liver in the graft seems to have a protective effect. Surveillance of opportunistic infections has also contributed to improved results. Infection, post-transplant lymphoproliferative disease, rejection and GVHD have still a major role in survival; however, antibody-mediated rejection has gained increased attention.

SUMMARY

Parenteral nutrition remains the main therapeutic resource in the management of intestinal failure, but intestinal transplant is a therapeutic option when this therapy has failed. Finding the balanced immunosuppression that minimizes risk of rejection while preventing occurrence of complications like post-transplant lymphoproliferative disease or GVHD is an ongoing challenge. The current survival rates of intestinal transplantation are similar to other solid organ transplant.
