Isolated Intestinal Transplant for Chronic Intestinal Pseudo-Obstruction in Adults: Long-Term Outcome

Abstract

BackgroundChronic intestinal pseudo-obstruction (CIPO) has been treated in adults by total parenteral nutrition (TPN) or, if complications arise, by multivisceral transplantation because the stomach is often involved. Eleven adults with CIPO were transplanted by intestinal graft in our center from 2000 to 2011. MethodsNine patients underwent isolated intestinal transplant and 2 patients had multivisceral transplant. Immunosuppression was represented by FK and steroids plus induction with alemtuzumab, daclizumab, or thymoglobulin. Average age at transplant was 33.5 years. We reported 1 graftectomy, followed by retransplantation. ResultsSeven patients are currently alive with working small bowel; cause of death was infection in the 4 remaining cases. In 9 isolated intestinal transplants, we performed different digestive reconstructions to allow gastric emptying. In 2 cases we were forced, after transplant, to perform ileostomy to improve intestinal motility. Graft and patient survival after 5 years are 60% and 70%, respectively, while after 10 years, 45% and 56%, respectively. ConclusionsAdults with CIPO and irreversible TPN complications benefit from isolated intestinal transplant with different surgical techniques to empty the native stomach: this strategy achieves good gastric emptying, with effective establishment of oral feeding and graft and patient survivals comparable to isolated intestinal transplant for short bowel syndrome.
