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.     

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.     

Simplified techniques in rat heterotopic small bowel transplantation

AIM: Establish a simplified heterotopic small bowel transplantation (SBT) in the rat. METHODS: Ninety pairs of male Wistar rats were used as donors and recipients. The whole small intestine with a vascular pedicle composed of superior mesenteric artery (SMA) and portal vein (PV) was harvested as the graft. Revascularization was accomplished by end-to-side anastomosis between donor SMA and recipient infrarenal aorta and cuffed end-to-end anastomosis between donor PV and left renal vein of recipient. The distal end of graft was exteriorized to form an enterostoma. RESULTS: Average time of an operation was 130 minutes and the mean warm ischemia time of grafts was 30 minutes. The technical success rate of this model was 100% and 7-day survival was 95.6% (86/90). CONCLUSION: This simplified technique was effective and practical to improve the outcome of rat heterotopic SBT.     

Vascular anastomosis and two-stage reconstruction of the gut in a living-related small bowel transplant recipient: a case report

AIM: We sought to discuss vascular anastomosis and gut reconstruction in a living-related small bowel transplantation recipient. METHODS: Living-related small bowel transplantation was performed successfully on a boy with short gut syndrome in two stages. In the first stage, 120 cm, of his mother's ileum was implanted into the recipient with the artery and vein anastomosed to the recipient's sigmoid artery and inferior mesenteric vein, respectively. The two ends of the implanted intestine were constructed as stomas. In the second stage, reconstruction of the continuity of the digestive tract was performed at 188 days after the initial transplantation. The residual small bowel was transected and both ends were anastomosed to the proximal and distal end of the graft in end-to-side fashion. The stomas were closed 30 and 43 days later. RESULTS: Both procedures were successful. Postoperative cytomegalovirus infection and acute rejection occurred successively and were controlled. No leakage of the reconstructed gut or other complications developed after the second procedure. The recipient is alive at 15 months with 8 kg an increase in weight. He is caring for himself independently and has a half-liquid diet, sometimes supplied with auxiliary enteral nutrition. A d-xylose test increased from 4.25% to 25% after the small bowel transplantation. CONCLUSIONS: Vascular anastomoses should be performed according to the state of graft and the recipient. The portal route is the first choice when possible. A two-stage gut reconstruction could decrease the incidence of complications, and offer a useful method in living-related small bowel transplantation.
