Abstract
OBJECTIVES This paper presents an innovative technique to address complex multiple hepatic vein (HV) reconstruction in right lobe graft living donor liver transplantation (RL-LDLT). METHODS A patient with hepatitis C virus-related cirrhosis underwent RL-LDLT. The graft had seven HVs, including: the right HV (17 mm); one segment VII HV (11 mm); two segment VI HVs (6 mm and 16 mm), and three segment V HVs. The graft weighed 663 g (53% of standard liver volume; ratio of graft weight to recipient body weight: 0.96). Each HV had significant drainage territory requiring reconstruction. A cryopreserved iliac vein graft was used to create a sleeve patch to incorporate the HV openings. The holes were anastomosed to their corresponding HV tributaries using continuous 6-0 polydioxanone (PDS) sutures. Two of the three segment V HVs were combined using a smaller iliac vein patch, which was anastomosed in an end-to-side fashion to a previously harvested recipient umbilical vein interposition graft. The other end of the umbilical vein graft was anastomosed to the larger iliac vein sleeve patch. RESULTS Overall, six HV openings were incorporated in one sleeve patch to allow a single wide anastomosis with the recipient inferior vena cava. Doppler ultrasound after reconstruction showed adequate flow patterns in all the HVs. CONCLUSIONS All-in-one sleeve patch graft venoplasty simplifies the reconstruction of multiple HVs and reduces warm ischaemia time in RL-LDLT with excellent outcomes.

Abstract
Hepatic venous outflow should be maintained for the success of living right lobe liver transplantation. In cases when the right hepatic vein is not the dominant venous drainage, the anterior branch of the middle hepatic vein and the accessory hepatic veins should be adequately drained to preserve graft function. One-step reconstruction of the hepatic veins became a preferred technique to create separate outflow for each of the graft's veins. In this report, we have described a quilt plasty technique for 1-step reconstruction of living donor hepatic veins using cadaveric cryopreserved aorta and iliac vein grafts.

Abstract
Arterial allograft represents a material of choice for primary arterial revascularization in liver transplantation (LT) when interposition of a vascular conduit is required. In case of non-availability of such graft, the use of cryopreserved vessels should be an interesting option. Three patients were grafted using a cryopreserved iliac artery allograft (CIAA) previously harvested and stored at -140°C in a tissue bank. An auxiliary partial LT was performed in one patient for acute liver failure. During follow-up, an efficient regeneration of the native hemi-liver was observed while atrophy of the auxiliary graft occurred, leading to functional portal vein and hepatic artery thrombosis at six and nine months, respectively. Two other patients presented with celiac trunk compression because of arcuate ligament without available arterial allograft in the donor. Late arterial thrombosis occurred at six months in one patient without impairment of graft function. The last patient was alive and symptom free 29 months after LT with a patent cryopreserved arterial conduit. Our preliminary results suggest that CIAA might represent an efficient solution as vessel interposition for primary arterial hepatic revascularization in LT setting when no other suitable graft is available. However, long-term patency of CIAA remains questionable.

Abstract
BACKGROUND Controversy remains over whether the middle hepatic vein should be included in the liver graft in right liver living donor liver transplantation. Congestion in the anterior sector of a right liver graft can cause graft malfunction, which is especially devastating in the case of a graft with marginal size in relation to recipient body size on top of poor pre-transplant recipient status. The case we report here highlighted the importance of the middle hepatic vein in right liver living donor liver transplantation. METHODS We illustrated the rectification of outflow obstruction of the middle hepatic vein in the anterior sector of right liver graft caused by technical error during transplantation. The rectification was performed with emergency re-routing using an artificial conduit. RESULT Congestion in the anterior sector of the graft improved immediately and the patient's postoperative liver function test results improved gradually. CONCLUSIONS The middle hepatic vein is important for effective drainage of the anterior sector of a right liver graft. The re-routing technique described in the report can also be applied to cases in which the middle hepatic vein is injured during hepatectomy requiring immediate reconstruction.

Abstract
BACKGROUND/PURPOSE We often encounter unresectable pancreatic cancer due to invasions of the major vessels. Vascular resection for locally advanced pancreatic cancers has an advantage in en block local resection. There are potential cases in which good outcomes can be achieved by arterial resection. METHODS Pancreatectomy (including total pancreatectomy in 15 cases, pancreatoduodenectomy in 7 cases and distal pancreatectomy in one case) was performed in 23 cases of invasive ductal carcinoma of the pancreas, in combination with resection and reconstruction of the hepatic artery in 15 cases, the superior mesenteric artery in 12 cases (there are overlaps) and the portal vein in 20 cases. RESULTS The median operating time was 686 min (416-1,190 min) and the median blood loss was 2,830 ml (440-19,800 ml). This shows that the surgery was highly-invasive. The operative mortality rate was 4.3%. On the basis of the UICC classification, there were 2 cases of Stage IIa, 4 cases of Stage IIb, 9 cases of Stage III, 8 cases of Stage IV, while there were 18 cases (78.3%) of R0 resection. On the other hand, the final histological findings showed that there were 8 cases (34.8%) of M1 (liver and non-regional lymph node metastases), so it is thought that decisions on operative indications should be not be made slightly. As for the overall survival rate, the 1-year survival rate was 51.2% and the 3-year survival rate was 23.1% while the median survival time (MST) was 12 months. As for 15 cases of M0, the 1-year survival rate was 61.9% and the 4-year survival rate was 38.7% while the MST was 16 months. On the other hand, the MST was poor (10 months) in 8 cases of M1, showing that a statistically significant difference was observed depending upon the degree of metastasis (log-rank P = 0.0409). In 18 cases of R0, the 1-year survival rate was 67.2%, the 4-year survival rate 30.2% and the MST 13 months, respectively, while in 5 cases of R1 and R2, the MST was 6 months, showing that there was a statistically significant difference between R0 cases and R1, R2 cases (log-rank P = 0.0002). CONCLUSIONS Further discussion is required concerning surgical indications and significance. However, it is thought that resection is useful only when surgery of R0 has taken place for selected locally advanced pancreatic cancer (M0).

Abstract
The harvesting of the middle hepatic vein (MHV) with the right lobe graft for living-donor liver transplantation allows an optimal venous drainage for the recipient; however, it is an extensive operation for the donor. This is a prospective, nonrandomized study evaluating liver functions and early clinical outcome in donors undergoing right hepatectomy with or without MHV harvesting. From August 2005 to July 2007, a total of 100 donor right hepatectomies were performed with (n = 49) or without (n = 51) the inclusion of the MHV. The decision to take MHV was based on an algorithm that considers various donor and recipient factors. There was no donor mortality in donors in either group. Overall complication rate was higher in MHV (+) donor group, however when remnant liver volume was kept above 30%, complication rates were similar between the groups. The results of this study show that right hepatectomy including the MHV neither affects morbidity nor impairs early liver function in donors when remnant volume is kept above 30%. The decision, therefore, of the extent of right lobe donor hepatectomy should be tailored to the particular conditions considering the graft quality and metabolic demand of the recipient.

Abstract
The extended application of living donor liver transplantation (LDLT) has revealed the problem of graft size mismatching called "small-for-size (SFS) graft syndrome." The initial trials to resolve this problem involved increasing the procured graft size, from left to right, and even extension to include a right lobe graft. Clinical cases of living right lobe donations have been reported since then, drawing attention to the risks of increasing the liver volume procured from a living donor. However, not only other modes of increasing graft volume such as auxiliary or dual liver transplantation, but also control of the increased portal pressure caused by an SFS graft, such as a portosystemic shunt or splenectomy, have been trialed with some positive results. To establish an effective strategy for transplanting SFS grafts and preventing SFS graft syndrome, it is essential to have precise knowledge and tactics to evaluate graft quality and graft volume, when performing these LDLTs with portal pressure control. We reviewed the updated literature on the pathogenesis of and strategies for using SFS grafts.

Abstract
Split liver transplantation and living donor liver transplantation (LDLT) commonly use a right liver graft without the middle hepatic vein (MHV). Although tributaries of the MHV are not reconstructed in the majority of cases, the alterations of the microcirculation and its regional functions remain unknown. We addressed these issues by assessing liver tissue indocyanine green (ICG) uptake with near-infrared spectroscopy (NIRS) in 21 donors. After graft procurement, visual inspection (before and after hepatic arterial clamping) and Doppler examination of the veno-occlusive region were performed. Bolus ICG (100 microg/kg) was then administered intravenously. Blood ICG at the finger tip was measured with pulse dye densitometry, whereas the liver ICG concentrations in the veno-occlusive and non-veno-occlusive regions were simultaneously measured for 15 minutes by NIRS. We estimated the hepatic ICG uptake rate constants in the veno-occlusive region (Ku-oc) and non-veno-occlusive region (Ku-non). Changes in sinusoidal perfusion in the veno-occlusive region were expressed by the ratio of Ku-oc to Ku-non (Roc/non). The median value of Roc/non was 0.47, although it ranged from 0.13 to 0.94. Roc/non was related to the extent of liver surface discoloration before and after hepatic arterial clamping (P = 0.03 and 0.01, respectively). In conclusion, sinusoidal perfusion was impaired in the veno-occlusive regions of living donor livers, but the magnitude of the effect varied greatly. Measurement of hepatic ICG uptake by NIRS could become a valuable tool for assessing the indication for venous reconstruction in LDLT and/or split donor liver transplantation.

Abstract
BACKGROUND The availability of a venous graft is limited in the setting of living donor liver transplantation (LDLT), and the management of the middle hepatic vein middle hepatic vein tributaries in right lobe LDLT still remains controversial. METHODS Twenty-three right lobe LDLT grafts, with the reconstruction of middle hepatic vein tributaries using the explanted portal veins from the explanted livers, were evaluated for the patency, postLDLT liver function tests, and graft survival. RESULTS The methods of outflow reconstruction were classified into three types: the interposition of the graft to the middle/left hepatic vein (n=12), to the vena cava (n=9), and to the vena cava as a co-orifice with the graft right hepatic vein (n=2). The 1- and 3-year patency rates were 76.7% and 76.7% respectively, with the graft occlusion in five cases. The occluded cases (n=5) had significantly higher aspartate aminotransferase and alanine transaminase levels as compared with those of patent cases (n=18) at 4 weeks after transplantation (P<0.01). However, there was no significant difference in the total bilirubin and prothrombin time in either group during the observation periods. The 1- and 3-year graft survival rates were 91.1% and 91.1%, respectively. In addition, there was no graft loss due to occlusion. CONCLUSION The use of the recipient's explanted full-length hilar portal vein for the reconstruction of the middle hepatic vein tributaries is thus considered to be a feasible and valuable strategy in the setting of a right lobe LDLT, where appropriate vascular grafts are not always available.

Abstract
In living donor liver transplantation (LDLT), the standard right graft has been adopted by many centers to meet the metabolic demands of large recipients. In conventional right liver graft, congestion at anterior section may be problematic especially when graft volume is insufficient. We previously introduced a technical aspect of modified extended right hepatectomy (MERH), in which the middle hepatic vein was excavated by preserving the entire segment 4 (Sg4) to the donor. In this report, we investigated the safety of donors who received MERH. Between August 2002 and July 2005, 97 donors underwent right liver donation. MERH was considered when remnant-left liver volume exceeded 35% of whole liver. Eighteen donors underwent MERH (MERH group, n=18). We compared the clinical outcomes of MERH group with those of donors who underwent conventional right hepatectomy (RH) with remnant liver volume exceeding 35% (RH group, n=37). No donor mortality occurred. No intra-operative transfusion and no re-operation were performed. There were no differences in operative time (290.8 min in MERH group vs. 297.0 min in RH group, respectively), blood loss (453.3 ml vs. 426.5 ml), and postoperative hospital stay (12.5 days vs. 12.8 days) between the two groups (P>0.05). Period of drain removal was longer in MERH group (12.5 days vs. 9.4 days, P<0.05). But, there was no difference in complication rate between the two groups (11/18 vs. 23/37, P>0.05). Computed tomography scan showed that congestion of Sg4 was occurred in 13 out of 18 MERH donors in early postoperative period, but all recovered at 4 months. The regeneration of the remnant liver after MERH and RH were similar (209.8% vs. 200.0% at 4 months, P>0.05). Our results show that MERH did not impair recovery or liver regeneration in donors, and indicate that MERH can be safely done in adult LDLT when the remnant liver exceeds 35%.

Abstract
Congestion of the anterior sector may lead to graft failure in right lobe grafts. Selective drainage of the prominent segment 5 and/or 8 veins is proposed to overcome this problem. Different vascular conduits may be used during drainage of the anterior sector. In this study, we evaluated the efficiency of the vascular conduits. Between June 1999 and December 2005, 190 patients underwent living donor right lobe liver transplantation and reconstruction of segment 5 and/or 8 veins was performed in 48 patients (25.2%). Two groups were formed according to the types of vascular conduits. Cryopreserved cadaveric iliac artery (n = 28) and cryopreserved cadaveric iliac vein (n = 8) were used in group A. In group B, recipient saphenous vein (n = 6), recipient umbilical vein (n = 5) and recipient collateral omental vein (n = 1) were used for reconstruction. The graft-recipient weight ratio, mean duration of anhepatic phase and MELD scores between two groups were not significantly different. All of the conduits were found to be patent just after reperfusion and in the early postoperative period by Doppler ultrasonography. In follow-up period of 1 year, four (11%) patients died in group A, two patients (16%) in group B. One of these patients died because of sepsis started from the saphenous vein incision site. None of the patients dying in the two groups were lost due to venous outflow problems. This study proves the efficacy of drainage of segment 5 and/or 8 veins using cryopreserved cadaveric vascular conduits. Every effort should be employed to store cadaveric iliac vessels, otherwise, whole other additive surgical intervention to ensure vascular conduit may lead uninvited serious complication.

Abstract
Congestion in the anterior section in a right liver (RL) without a middle hepatic vein (MHV) may lead to graft dysfunction. To solve this problem, an RL draining MHV branches with autologous or cryopreserved vessels can be introduced. However, these vessels are often unavailable, and their preparation is time-consuming. An expanded polytetrafluoroethylene (ePTFE) graft may be used for anterior section drainage. Between February and November 2005, 26 recipients underwent RL liver transplantation draining MHV branches with an ePTFE graft (group P). Twenty-six ePTFE grafts (6 or 7 mm in internal diameter) drained 35 MHV branches on the back table to the graft right hepatic vein or to the recipient's inferior vena cava. The patency of the ePTFE graft was checked with computed tomography scans of the liver. The outcome of group P was compared with those of an RL group with MHV (group M, n=17) and an RL group without reconstruction of MHV or its tributaries (group R, n=85). The 1-month and 4-month patency rates (PRs) of the ePTFE grafts were 80.8% (21/26) and 38.5% (10/26). All showing early obstruction of the ePTFE graft had congestion in the anterior section, but all showing late obstruction were asymptomatic. The 1-month PRs of group P were comparable to, but the 4-month PRs were lower than, those of group M (both 94.1%; P<0.05). However, 1-year patient and graft survival rates of group P (both 100%) were comparable to those of group M (94.1% and 100%) and better than those of group R (83.5% and 88.2%; P<0.05). In conclusion, the early PR of group P was good, and late obstruction of the ePTFE graft had no impact on congestion in the anterior section or patient survival. Therefore, an ePTFE graft may be a useful interposition material for anterior section drainage in RL transplantation without serious complications.

Abstract
Although autologous vein grafts have been used for portal vein (PV) reconstruction after long-segment portal vein resection during surgery for hilar bile duct cancer, their procurement prolongs operation time and increases morbidity. Less is known regarding the use of homologous vein grafts. The feasibility of homografts for PV reconstruction was preliminarily evaluated in two patients who underwent curative resection for hilar cholangiocarcinoma. Both patients underwent left lobectomy, caudate lobectomy, bile duct resection, and segmental PV resection and interposition vein graft reconstruction. The iliac vein homografts were obtained from deceased organ donors and stored for 1-2 days in cold preservation solution without freezing. Neither immunosuppression nor anticoagulation was attempted. One patient has shown good PV patency for 27 months. The second patient, who had received adjuvant chemoradiotherapy, showed an asymptomatic waisting at the proximal PV anastomosis site after 4 months, which was relieved by percutaneous balloon dilatation, and has been doing well for 12 months. In conclusion, our preliminary experience with these two patients suggests that cold-stored iliac vein homografts can be considered as PV substitutes after long PV segment resection during extensive hepatobiliary surgery.

Abstract
Serious complications have occurred in a considerable proportion of living donors of liver transplants, but data from a single high-volume center has rarely been available. We analyzed the medical records of donors and recipients of the first 1,000 living donor liver transplants, performed at Asan Medical Center from December 1994 to June 2005, with a focus on donor safety. There were 107 pediatric and 893 adult transplants. The most common diagnoses were biliary atresia in pediatric recipients (63%) and hepatitis B-associated liver cirrhosis (80%) in adult recipients. Right lobe donors were strictly selected based on liver resection rate and steatosis. From 1,162 living donors, 588 right lobes, 6 extended right lobes, 7 right posterior segments, 464 left lobes, and 107 left lateral segments were obtained. Of these, 837 grafts were implanted singly, whereas 325, along with 1 cadaveric split graft, were implanted as dual grafts into 163 recipients. The 5-yr survival rates were 84.8% in pediatric recipients and 83.2% in adult recipients. There was no donor mortality, but 3.2% of donors experienced major complications. Until the end of 2001, the major donor complication rate was 6.7%, with most occurring in right liver donors. Since 2002, liver resection exceeding 65% of whole liver volume were avoided except for young donors with no hepatic steatosis, and the donor complication rate has been reduced to 1.3%. In conclusion, a majority of major living donor complications appear to be avoidable through the strict selection of living donor and graft type, intensive postoperative surveillance, and timely feedback of surgical techniques. Selection of right lobe graft should be very prudently considered if the donor right liver appears to be larger than 65% of the whole liver volume.
