Small bowel transplantation using grafts from living‐related donors. Two case reports

Abstract A living‐related small bowel transplantation (SBT) was performed in two pediatric patients with short bowel syndrome. In both cases, the donor was the patient's mother. The distal ileum (100 cm, 120 cm) was harvested and the ileocolic vessels, ileocecal valve, and terminal ileum were left intact. The two donors were discharged from the hospital on postoperative days 15 and 6, respectively. Recipient 1 was a 2 year 6 month‐old boy with short bowel syndrome who underwent SBT due to loss of venous access. The graft vein was anastomosed to the recipient's infrarenal inferior vena cava. Despite triple immunosuppression (tacrolimus, steroid, and azathioprine), there were four episodes of rejection. The patient had been on total parenteral nutrition for almost his entire post‐transplant course. He died from Pneumocystis carinii pneumonia 16 months after the transplantation. Recipient 2 was a 4 year 5 month‐old girl with short bowel syndrome who underwent an isolated small bowel transplantation because of recurrent line sepsis. Her pretransplant bilirubin was 8.0 mg/dl and a biopsy showed severe fibrosis. The graft vein was anastomosed to the recipient's inferior mesenteric vein. After transplantation, her bilirubin level became normal within 10 days. Triple immunosuppression (tacrolimus, steroid, and cyclophosphamide) together with a 3‐day course of OKT‐3 made her post‐transplant course feasible. After overcoming a single episode of rejection she left the hospital 4 months after SBT. The patient is currently (10 months after transplantation) hospitalized due to rejection, which is being successfully controlled, and she is off total parenteral nutrition. From our experience, harvesting of the distal ileum for use as a bowel graft can be safely performed. The advantages of living‐related grafts, optimal graft length, and choice of vascular reconstruction in SBT are yet to be explored.     

Progressive functional adaptation of segmental bowel graft from living related donor

We report a patient with short gut syndrome successfully treated with living related bowel transplantation. A 27-year-old Caucasian man was referred after traumatic loss of almost the entire bowel from the third portion of duodenum to the sigmoid colon. His HLA-identical sister volunteered as a donor. A 200-cm segment of ileum was successfully transplanted under tacrolimus-based immunosuppression. The posttransplant course was uneventful, without rejection or infectious complication. Total parenteral nutrition was discontinued 1 week posttransplant. At 6 months the patient had returned to his preinjury weight. Water and D-xylose absorption as well as fecal fat studies were markedly abnormal 1 month posttransplant but normalized by 6 months. The donor recovery was uneventful. A well-matched segmental ileal graft from living donor can provide complete rehabilitation for patients with short gut syndrome. We documented a progressive functional adaptation of the ileal graft, resulting in normal absorption by 5 months posttransplantation.     

Favorable nutritional outcome after isolated liver transplantation for liver failure in a child with short bowel syndrome

A patient with short gut syndrome presented with end-stage liver disease. She underwent an isolated liver transplantation at the age of 3.5 years. Parenteral nutrition was discontinued 1.5 years after surgery. At 7 years of age, the patient has maintained normal nutritional indices and growth while on a normal oral diet. This observation suggests that liver transplantation alone can be a valuable alternative to the combined small bowel/liver transplantation in short bowel syndrome when intestinal adaptation is expected and if the ileocecal valve is present and that improvement of gut function can occur after successful liver transplantation.     

Successful treatment of trauma-induced short bowel syndrome with early living related bowel transplantation

BACKGROUND:: Total parenteral nutrition (TPN) is a life-saving therapy for patients with short bowel syndrome. However, TPN is associated with a high incidence of serious complications, poor quality of life, and elevated cost. An attempt was made to avoid TPN-related complications associated with trauma-induced short bowel syndrome by using early living related donor bowel transplantation. METHODS:: Three men 27 to 30 years of age with trauma-induced short bowel syndrome received early living related donor bowel transplantation using segmental ileal grafts. RESULTS:: All the donors had an uncomplicated postoperative course. After a mean follow-up period of 40 months, all three recipients were alive and well, and did not require any TPN support. The ileal graft adapted perfectly to support fully the nutritional needs of young, active individuals. CONCLUSIONS:: Early living related donor bowel transplantation is a successful treatment for trauma-induced short bowel syndrome. It is associated with a lower incidence of complications, better quality of life, and lower cost than long-term TPN.     

Treatment of short gut syndrome with early living related small bowel transplantation

AIM: To investigate the results of treating short bowel syndrome with an early living related small bowel transplantation (SBT). METHODS: A 17-year-old boy with a 20-cm-long residual intestine due to necrotic volvulus received an early living related SBT from his mother. Donor-specific blood transfusion was performed for 8 weeks before transplantation, each time for 50 mL every week. Cytomegalovirus status in both donor and recipient was negative. A 160-cm distal ileal segment was removed from the donor. The graft ilecolic artery and vein were anastomosed to the recipient's infrarenal aorta and caval vein. The proximal end of the graft was anastomosed end-to-end to the residual recipient jejunum; the distal anastomosis, between the distal end of the graft and transverse colon. An ileostomy was also performed. Immunosuppression, infection prophylaxis, and antithrombotic and nutrition support were given postoperatively. RESULTS: The donor had an uneventful recovery. No technical complications were observed. The recipient was alive and well at 31 weeks after the operation. No graft rejection or infection was observed. He was off TPN 8 weeks after the operation and took low-fat food. The D-xylose test in the recipient was almost normal. CONCLUSIONS: Early living related small intestine transplantation is a good treatment for short bowel syndrome.     

Living related intestinal transplantation for Churg-Strauss syndrome: a case report

Exceptionally, gastrointestinal involvement of Churg-Strauss syndrome (CSS) may require extensive bowel resection resulting in a short bowel syndrome. Living related intestinal transplantation (IT) has emerged as an alternative to deceased-donor IT in the management of patients with irreversible short bowel syndrome. Herein, we have presented a 35-year-old patient with isolated intestinal involvement of CSS lesions refractory to steroids and azathioprine requiring multiple abdominal resections resulting in an ultrashort bowel syndrome. A living related IT (from the mother) was performed. She underwent several acute rejection episodes treated with additional immunosuppressive therapy. Despite higher doses of immunosuppression, these repeated acute rejection episodes eventually evolved into a syndrome of chronic allograft rejection. Eventually, owing to her poor general condition and to avoid life-threatening infections, transplantectomy was inevitable. Recent immunologic studies indicate that peripheral mononuclear cells from patients with CSS secrete large amounts of T-helper type 1 and 2 cytokines. It is likely that patients with CSS are at higher risk for acute and chronic rejection after transplantation.
