Beyond 10 years, with or without an intestinal graft: Present and future?

Area of Science:

• Pediatric Surgery
• Transplantation Medicine
• Gastroenterology

Background:

• Long-term outcomes of intestinal transplantation in pediatric patients are not well-established.
• Understanding the 10-year posttransplant course is crucial for optimizing patient care.

Purpose of the Study:

• To evaluate the 10-year patient and graft survival rates after intestinal transplantation in children.
• To assess long-term functional outcomes, including nutritional status, physical growth, and organ function.
• To identify factors associated with improved graft survival and long-term complications.

Main Methods:

• Retrospective analysis of 71 children undergoing intestinal transplantation between 1989 and 2007.
• Comparison of outcomes between patients with a functional graft (group 1, n=26) and without (group 2, n=9).
• Assessment of patient survival, graft survival, nutritional status, physical growth, energy absorption, histology, renal function, and complications.

Main Results:

• Ten-year patient survival was 53% and graft survival was 36%.
• Patients with functional grafts were weaned off parenteral nutrition, but experienced micronutrient deficiencies and fat malabsorption.
• Liver transplantation and a 3-drug immunosuppression regimen (sirolimus or mycophenolate mofetil) improved graft survival.

Conclusions:

• Intestinal transplantation can achieve satisfactory long-term digestive function in children.
• Graft removal without retransplantation has a better prognosis than anticipated.
• Regular micronutrient monitoring, psychological assessment, and sirolimus use are recommended.
