Intestinal transplantation: an unexpected journey. Robert E. Gross Lecture

Area of Science:

• Gastroenterology and Hepatology
• Transplantation Surgery
• Immunology

Background:

• Pediatric intestinal failure necessitates complex management, often involving total parenteral nutrition (TPN).
• Complications of TPN, including liver disease and infection, drive the need for alternative therapies.
• Intestinal transplantation has emerged as a viable option for select pediatric patients.

Observation:

• Advancements in immunosuppressive drugs (cyclosporine, tacrolimus) have improved long-term graft survival.
• Innovations in organ procurement and preservation facilitate tailored intestinal grafts.
• Multidisciplinary care centers optimize outcomes for intestinal transplant recipients.

Findings:

• Improved immunosuppression and surgical techniques enhance survival rates in pediatric intestine transplantation.
• Understanding of host-versus-graft and graft-versus-host interactions informs management strategies.
• Risk-benefit analyses refine indications for intestinal transplantation based on TPN complication severity.

Implications:

• Intestine transplantation offers a life-saving therapy for pediatric patients with severe intestinal failure.
• Minimizing immunosuppression may further improve long-term outcomes and quality of life.
• Continued research into immunosuppression and multidisciplinary care is crucial for advancing the field.
