    OBJECTIVES: The right posterior segment graft can be selected in cases where neither the right nor left lobe graft satisfies the selection criteria for adult living donor liver transplant. However, vascular and biliary anatomy may cause technical difficulties in procurement of posterior segments in donors of living donor liver transplant and may require specific attention in vascular and biliary reconstruction in the recipient. In this study, we examined the feasibility of right posterior segment grafts in adult living donor liver transplants through donor safety and recipient outcomes and clarified the anatomic points of the surgical technique. MATERIALS AND METHODS: We retrospectively reviewed 296 cases of adult living donor liver transplants treated at Kumamoto University between August 2000 and March 2017. RESULTS: Among 296 cases, graft types were right lobe (n = 162), left lobe (n = 119), and right posterior segments (n = 9). Among donors, no significant differences were shown in operative time, blood loss, or incidence of postoperative complications between early and late phases among the 3 groups. Four cases ofright posterior segment had >2 biliary duct stumps, and 2 cases had 2 portal vein stumps. Among recipients, median actual graft-to-recipient weight ratio was 0.82% (range, 0.52%-1.22%), with no factors, including graft type, significantly associated with graft survival. Hepatic artery thrombosis and rupture of hepatic artery pseudoaneurysm occurred in 1 case as an early complication, and biliary anastomotic stricture occurred in 4 cases as a late complication. CONCLUSIONS: The right posterior segment graft may be an effective alternative in living donor liver transplant when no eligible candidates for conventional grafts are available among families and relatives. Careful preoperative anatomic evaluations and simulations are important.

  • Portal vein stenting blocked the inflow tract and completely resolved bile duct varices, formed by cavernous transformation of the portal vein

    There is no established treatment for bleeding bile duct varices (BDVs). We report the first case of portal vein (PV) stenting completely eradicating bleeding BDVs. A 70-year-old male with malignant lymphoma developed BDVs due to PV obstruction, which had caused compression and stricture of the distal bile duct. Endoscopic retrograde cholangiography was performed to evaluate the stricture and bleeding from the ruptured BDV was observed. Endoscopic hemostasis was difficult, requiring reopening of the extra-hepatic PV and reducing the blood flow to the BDVs for hemostasis. Therefore, PV stenting was performed. During the procedure, portal angiography confirmed an inflow tract to the BDVs. Therefore, covered stents were placed in the PV and adjusted to block the inflow tract to the BDVs at the distal end. After stenting, the BDVs were successfully blocked and all PV blood flowed through the stent placed in the extra-hepatic PV. Two weeks after stenting, the BDVs had disappeared completely and the bleeding has not recurred for months. We experienced a case in which PV stenting not only reopened an obstructed PV but also successfully occluded the inflow tract. This case demonstrates the potential of PV stenting for the treatment of hemorrhagic BDVs.
