  High quality biaxially textured yttria stabilized zirconia (YSZ) thin films, as buffer layers of coated conductors, were deposited on hastelloy substrates by ion beam assisted deposition (IBAD) method with different assisting ion energy Ei. The roles of assisting ion beam and the influences of ion energy Ei on the structure of the films were studied. It was found that both the out-of-plane alignment and in-plane texture of the IBAD-YSZ films are sensitive to the variation of Ei. The results are explained in the paper by different damage tolerance of the differently oriented grains to ion bombardment.

Objective: We summarized our experience of living-related small bowel transplantation and postoperative management of 3 patients with short gut syndrome.

Methods: Patient #1, an 18-year-old boy, received a 150-cm segment of distal ileum with a vascular pedicle of distal superior mesenteric artery and vein, which was donated by his father. Patient #2, a 15-year-old boy, received a 160-cm graft of distal ileum from his mother. Patient #3, a 17-year-old boy, received a 170-cm graft of distal ileum from his father. The graft artery and vein were anastomosed to the recipient infrarenal aorta and vena cava, respectively, in end-to-side fashion using 7/0 Prolene suture. Intestinal continuity was restored by anastomosis of proximal end of the graft to the recipients' own proximal jejunum, the distal end was left open as a stoma. The recipient distal gut was anastomosed to the distal end of the graft. All 3 recipients were given FK506 (tacrolimus) regularly combined with periodic mycophenolate mofetil. In cases of acute rejection, large doses of steroids were administered to the recipients.

Results: The recipients and donors had fairly unremarkable postoperative courses. So far, patient #1 has survived for 7 years and 6 months with a well-functioning graft and without requirement for total parenteral nutrition (TPN) support. His body weight increased 20 kg and of his life quality has dramatically improved. Patient #2, however, died of acute rejection with fatal sepsis at 5 months after transplantation. Patient #3 has survived for 3 years and 8 months enjoying a normal life. Postoperative recovery of all 3 donors was unremarkable. They were discharged 12 days after surgery without complications.

Conclusion: Outcomes of the implantation using the distal ileum as a graft in living-related small bowel transplantation have been satisfactory for both recipients and donors. It is feasible to anastomose the graft artery and vein to the recipient infrarenal aorta and vena cava. The intestinal continuity can be restored by a 1-stage strategy with minimal risk to the recipient. Appropriate application and adjustment of immune suppressors are crucial for the recipients to experience high-quality lives.
