    ABSTRACT: Liver transplantation using ABO-incompatible grafts is rarely performed because the reported outcome is poorer than with compatible grafts. We report our positive experience with adult-to-adult living-donor liver transplant (LDLT) using ABO-incompatible grafts. The immunosuppressive protocol consisted of plasmapheresis/intravenous immunoglobulin infusion before LDLT followed by thymoglobulin induction and splenectomy, maintenance with tacrolimus/cyclosporine (FK/CSA), mycophenolate mofetil, and a rapid steroid taper. Plasmapheresis was planned for up to 3 months after LDLT aiming at maintaining the anti-ABO titers level below 1:16. Liver biopsies were routinely stained for humoral rejection with complement 4d (C4d) and for biliary damage with cytokeratin 7. Between January 2003 and September 2004, five patients, mean age 59 years, received an ABO-incompatible LDLT. Patient and graft survival was 80% at mean follow-up of 43 months (range, 34-54) for the four surviving patients. One patient died 4 months after LDLT. Humoral rejection occurred in one patient whereas acute cellular rejection was diagnosed in four patients. ABO-incompatible LDLT can be performed with patient and graft survival similar to compatible LDLT. Minimization of immunosuppression is possible, and chronic biliary damage is not the norm. Better tools than complement 4d staining must be researched to diagnose the features of immunologic damage to the graft. If these results will be confirmed in a greater number of patients, ABO-incompatible LDLT may be proposed when ABO-compatible donors are not available or when the ABO-incompatible donor is the better candidate.

    ABSTRACT: The presence of two or more hepatic ducts for biliary anastomosis in adult-to-adult right liver transplantation is not uncommon. In the case described here, the graft had two hepatic ducts: one corresponded anatomically to a normal right hepatic duct and the other ran parallel to the proper hepatic duct and drained into its distal to the cystic duct. Because of the small diameter of both duct orifices and the favorable length of the ducts, a cloaca type reconstruction was performed. This allowed the construction of a single and larger orifice for the biliary anastomosis. In case of multiple hepatic ducts of smaller caliber, this technique represents a practical and effective hepatoplasty allowing a single larger anastomosis in the recipient.

    ABSTRACT: The aim of our study was to analyze growth in children who underwent LDSB. The question was whether these children obtain linear growth and improvement of the Z-score for height and weight after the transplant. Three children with a mean age of 24 months underwent living-donor intestinal transplantation with 150 cm of terminal ileum. At a mean follow-up of 27 months height increased from 82.5 to 97.5 cm although Z-score for height did not improve, -2.679 to -2.675. Mean weight increased from 11.4 to 14.2 kg while Z-score for weight went from -1.916 to -2.409. Although these data are pertinent to only three children and the follow-up is slightly longer than two yr, it appears that while long-term survival and independency from TPN is achieved, only linear growth might be expected and catch-up growth does not occur.

    ABSTRACT: The division of the hepatic duct is one of the most challenging passages of the donor hepatectomy. We report our experience with the early division, prior to the liver parenchyma resection, of the hepatic duct and the definition of the biliary anatomy with a probe inserted in the proper hepatic duct. From February 2002 to December 2004, 40 donors (25 male, 15 female; mean age 34, range 20-57) underwent right hepatectomy. The yield was a single duct in 24 donors (60%), two ducts in 12 donors (30%), and three ducts in one donor (2.5%), and three donors had aberrant anatomy yielding two ducts (7.5%). By means of a ductoplasty, a single orifice for the recipient biliary anastomosis was obtained in 77.5% of the cases. Three donors (7.5%) suffered a resection surface bile leak. The technique of hepatic duct probing and early division provides a precise definition of the biliary anatomy and facilitates one of the most challenging passages of the donor hepatectomy. This technique should also contribute to maximizing the preservation of the vascular supply of the hepatic duct and the yield of a single orifice for the recipient anastomosis. At a median follow-up of 21 months (range 10-44), neither short- nor long-term complications had been caused by the small donor choledochotomy.
