RESUMO

BACKGROUND: Hepatitis B core antibody-positive (HBcAb+) graft is known as a risk for de novo hepatitis B virus (HBV) infection in recipients after liver transplantation (LT). However, little is known about the possibility or incidence of de novo HBV infections after LT in hepatitis B surface antigen-negative (HBsAg-)/HBcAb+ recipients using HBsAg-/HBcAb- grafts. The study aimed to evaluate the prevalence of de novo HBV infection in HBsAg-/HBcAb+ recipients using HBsAg-/HBcAb- grafts. A retrospective review was performed with the records of 1129 adult patients who underwent primary LT at a single institution in an HBV endemic area between January 2000 and December 2013. A total of 78 patients (6.9%) were reviewed for de novo HBV infection after LT. De novo HBV infection was developed in 1 patient (1.28%). The patient was a 65-year-old woman who underwent LT due to alcoholic liver cirrhosis. De novo HBV was not related to graft loss or death and well treated with tenofovir. In conclusion, de novo HBV infections may occur in HBsAg-/HBcAb+ recipients using HBsAg-/HBcAb- grafts, and caution is needed in these patients.

RESUMO

BACKGROUND: Urinary neutrophil gelatinase-associated lipocalin (uNGAL) is an early biomarker of renal injury. We examined the feasibility of using uNGAL as an early predictor of renal impairment in patients under calcineurin inhibitors in liver transplant recipients. METHODS: From urine samples obtained from liver transplant recipients, the glomerular filtration rate (GFR) at the time of urine sampling was compared with that at 5 to 7 months later. Patients were divided into 3 groups according to initial GFR and then divided into 2 groups according to the uNGAL level of 25 ng/mL. Progression of renal injury (PRI) was defined as a decrease in the GFR of more than 5 mL/min/1.73 m2 in the mild or moderate groups, or if a normal group patient shifted to the mild or moderate group. RESULTS: Fifty-one patients were enrolled. The mean uNGAL level was higher in the moderate group than in the normal and mild groups (18.38 ± 14.31 vs 7.74 ± 8.13; P < .01). A proportion of uNGAL-high was also higher in the moderate group than in the mild group (40% vs 5%; P = .03). uNGAL-high was a risk factor for 6-month PRI (odds ratio, 60.375; 95% confidence interval, 1.283-4088.25; P = .037) and 1-year PRI (odds ratio, 21.311; % confidence interval, 0.947-479.578; P = .054). CONCLUSIONS: A uNGAL of >25 ng/mg can be a marker for moderate renal impairment (GFR of 30-59 mL/min/1.73 m2) and a predictor of PRI at 6 months in patients using calcineurin inhibitors. Renal protection strategies should be considered in liver transplant recipients with a uNGAL of >25 ng/mg in spot urine sampling.

RESUMO

Alveolar hemorrhage is a life-threatening clinical syndrome often initially thought to be atypical pneumonia. Association with hematopoietic stem cell transplantation is well studied, but not with solid organ transplantation. We report a case of a 54-year-old woman presented with fever and shortness of breath on the third posttransplant day after deceased donor liver transplantation. Imaging studies showed diffuse bilateral pulmonary infiltrates and a positive sequential bronchoalveolar lavage test was revealed during bronchoscopy. Cytomegalovirus antigenemia was present in 8/200,000 white blood cells; Aspergillus galactomannan and Pneumocystis jirovecii were also present. However, only Aspergillus hyphae were found in the sputum culture. Management strategy aimed to treat underlying infections, provide adequate respiratory support, and control inflammation. We proposed that diffuse alveolar hemorrhage should be considered as differential diagnosis in early pulmonary complications after liver transplantation. Early diagnosis and aggressive treatment protocol is the key for a good outcome.

RESUMO

BACKGROUND: There may be concerns about purely laparoscopic donor right hepatectomy (PLDRH) compared with open donor right hepatectomy, especially when performed by surgeons accustomed to open surgery. This study aimed to describe technical tips and pitfalls in PLDRH. METHODS: Data from donors who underwent PLDRH at Seoul National University Hospital between December 2015 and July 2017 were analysed retrospectively. Endpoints analysed included intraoperative events and postoperative complications. All operations were performed by a single surgeon with considerable experience in open living donor hepatectomy. RESULTS: A total of 26 donors underwent purely laparoscopic right hepatectomy in the study interval. No donor required transfusion during surgery, whereas two underwent reoperation. In two donors, the dissection plane at the right upper deep portion of the midplane was not correct. One donor experienced portal vein injury during caudate lobe transection, and one developed remnant left hepatic duct stenosis. One donor experienced remnant portal vein angulation owing to a different approach angle, and one experienced arterial damage associated with the use of a laparoscopic energy device. One donor had postoperative bleeding due to masking of potential bleeding foci owing to intra-abdominal pressure during laparoscopy. Two donors experienced right liver surface damage caused by a xiphoid trocar. CONCLUSION: Purely laparoscopic donor hepatectomy differs from open donor hepatectomy in terms of angle and caudal view. Therefore, surgeons experienced in open donor hepatectomy must gain adequate experience in laparoscopic liver surgery and make adjustments when performing PLDRH.

RESUMO

Although laparoscopic donor hepatectomy is increasingly common, few centers with substantial experience have reported the results of pure laparoscopic donor right hepatectomy (PLDRH). Here, we report the experiences of 60 consecutive liver donors undergoing pure laparoscopic donor hepatectomy (PLDH), with most undergoing right hepatectomy. None of the 60 donors who underwent PLDH had intraoperative complications and none required transfusions, reoperation, or conversion to open hepatectomy. Forty-five donors who underwent PLDRH between November 2015 and December 2016 were compared with 42 who underwent conventional donor right hepatectomy (CDRH) between May 2013 and February 2014. The total operation time was longer (330.7 vs 280.0 minutes; P < .001) and the percentage with multiple bile duct openings was higher (53.3% vs 26.2%; P = .010) in the PLDRH group. However, the length of postoperative hospital stay (8.4 vs 8.2 days; P = .495) and rate of complications (11.9% vs 8.9%; P = .733) and re-hospitalizations (4.8% vs 4.4%; P = 1.000) were similar in both groups. PLDH, including PLDRH, is feasible when performed by a highly experienced surgeon and transplant team. Further evaluation, including long-term results, may support these preliminary findings of comparative outcomes for donors undergoing PLDRH and CDRH.

RESUMO

BACKGROUND: Generic immunosuppressants may be cost-effective if clinical outcomes are equivalent to the brand-name medications. Mycophenolate mofetil in the form of My-rept may be cost-effective being a generic immunosuppressant, which is available as a 500-mg tablet as well as a 250-mg capsule (Chong Kun Dang Pharmaceutical Corporation, Seoul, Korea). OBJECTIVE: This study aimed to evaluate the efficacy, safety, cost-effectiveness, and convenience of My-rept 500-mg tablets in liver transplant recipients. SETTING: The setting was an outpatient liver transplantation clinic of a tertiary hospital in Korea. METHOD: A phase 4, single-center, open-label, noncomparative study was undertaken. A total of 50 patients were recruited. Acute transplant rejection, changes in blood chemistry, white blood cell count, assessments of renal function, occurrence of adverse drug reactions, and other characteristics of the patients were recorded for 24 weeks. After study termination, a satisfaction survey was conducted. RESULTS: All enrolled patients and their liver grafts had survived for 24 weeks post-transplantation. No episodes of acute rejection were reported. Nine patients (18.8%) presented with adverse drug reactions that had been commonly reported with the use of other mycophenolate mofetil products, and no serious adverse drug reactions were reported. CONCLUSION: In conclusion, the My-rept 500-mg tablet appears to be feasible and convenient for administration to recipients of a liver transplant.

RESUMO

OBJECTIVE: Liver resection (LR) and living-donor liver transplantation (LDLT) are considered the two potentially curative treatments for hepatocellular carcinoma (HCC). The aim of this study was to investigate whether there is a difference in the oncologic outcomes between LR and LDLT according to tumor biology. METHODS: Patients (137 LDLTs and 199 LRs) were stratified into four groups by tumor biology according to the number of risk factors for recurrence (preoperative alpha-fetoprotein >200 ng/mL, Edmonson grade 3 or 4, tumor size >3 cm, and presence of microvascular invasion). RESULTS: In the favorable tumor biology patients (groups I and II), there was a significantly worse recurrence-free survival rate in those patients who underwent LR compared to those who underwent LDLT (group I, P = .002; group II, P = .001). The overall survival rates in the LR and LDLT groups were not different (group I, P = .798; group II, P = .981). In the poor tumor biology patients (groups III and IV), there was no significant difference between the two groups in terms of recurrence-free survival rate (group III, P = .342; group IV, P = .616). The LDLT group showed a significantly lower overall survival rate (group III, P = .001; group IV, P = .025). CONCLUSIONS: Primary LDLT should not be recommended in early stage HCC patients with poor tumor biology because of lower survival rates and a high chance of HCC recurrence.

RESUMO

OBJECTIVE: Prothrombin induced by the absence of vitamin K or antagonist-II (PIVKA-II) is a useful tumor marker for hepatocellular carcinoma (HCC). However, the usefulness of post-transplantation surveillance with PIVKA-II is not clear. We evaluated the clinical value of PIVKA-II in monitoring HCC recurrence after living-donor liver transplantation (LDLT). METHODS: One hundred twenty patients who had undergone LDLT for HCC from February 1999 to December 2010 and whose serum alpha-fetoprotein (AFP) and PIVKA-II had been measured sequentially before and after LDLT were included in this study. Patients were classified into four groups according to the preoperative level of AFP and PIVKA-II (group I, normal AFP and PIVKA-II; group II, elevated AFP; group III, elevated PIVKA-II; and group IV, elevated both AFP and PIVKA-II). RESULTS: Preoperative PIVKA-II level tended to increase with increasing tumor size, number of nodules, presence of microvascular invasion, and poor differentiation. In 27 patients developing recurrent HCC after LDLT, the sensitivity of AFP and PIVKA-II was 59.2% and 88.8%, respectively. When the two markers were combined, the sensitivity increased to 92.5%. Especially, the sensitivity for PIVKA-II was high at groups I and III (100.0% for both, respectively). In patients in groups I, III, and IV, an elevated PIVKA-II level was the most common first sign of HCC recurrence after LDLT. An elevated PIVKA-II level was the most common first sign of recurrence, regardless of recurrence site. CONCLUSIONS: PIVKA-II might be a useful tumor marker in the monitoring of recurrence after LDLT, complementary to AFP.

RESUMO

Herein, we report our experience of performing allogeneic orthotopic liver transplantation (LT) in nonhuman primates. We designed an allogeneic ABO-compatible orthotopic LT model in monkeys in a manner similar to that used in humans. We applied almost the same surgical procedures used for human conventional deceased donor LT. A total of 6 monkeys underwent allogeneic LT. One cynomolgus monkey aged 45 months (3.4 kg) and 5 rhesus macaque monkeys aged 50.2 ± 14.8 months (5.40 ± 0.33 kg) were used as recipients. In the donor surgery, the liver was perfused in situ through the aorta using cold histidine-tryptophan-ketoglutarate solution. The portal vein (diameter, 5-10 mm), supra- and infra-hepatic inferior vena cava (IVC) (diameter, 12-15 mm), and common bile duct (diameter, 1.5-3.0 mm) were dissected out. The hepatic artery was kept in continuity with the celiac trunk and abdominal aorta up to the iliac bifurcation (diameter, 5-6 mm). The mean graft weight was 102.0 g (94.8-111.0 g). Recipient surgery was conducted in parallel. After recipient hepatectomy, the graft was implanted. The suprahepatic IVC and portal vein were anastomosed to those of the graft. After reperfusion, the infrahepatic IVC was anastomosed. The aorta conduit of the graft was anastomosed to the infrarenal aorta of the recipient in a retrocolic end-to-side manner. Biliary reconstruction was performed in a duct-to-duct anastomosis with cholecystectomy. Mean operative time was 107.0 minutes for donor and 198.2 minutes for recipient. There was one operative death due to unknown cause. In conclusion, for allogeneic orthotopic LT in nonhuman primate model, we can apply almost the same procedure used for human conventional deceased donor LT in a similar manner.

RESUMO

BACKGROUND: Although transarterial chemoembolization is recommended as the standard treatment for Barcelona Clinic Liver Cancer stage B hepatocellular carcinoma (BCLC-B HCC), other treatments including liver resection have been used. This study aimed to determine the survival benefit of treatment strategies including resection for BCLC-B HCC compared with non-surgical treatments. METHODS: The nationwide multicentre database of the Korean Liver Cancer Association was reviewed. Patients with BCLC-B HCC who underwent liver resection as a first or second treatment within 2 years of diagnosis and patients who received non-surgical treatment were selected randomly. Survival outcomes of propensity score-matched groups were compared. RESULTS: Among 887 randomly selected patients with BCLC-B HCC, 83 underwent liver resection as first or second treatment and 597 had non-surgical treatment. After propensity score matching, the two groups were well balanced (80 patients in each group). Overall median survival in the resection group was better than that for patients receiving non-surgical treatment (50·9 versus 22·1 months respectively; P < 0·001). The 1-, 2-, 3- and 5-year overall survival rates in the resection group were 90, 88, 75 and 63 per cent, compared with 79, 48, 35 and 22 per cent in the no-surgery group (P < 0·001). In multivariable analysis, non-surgical treatment only (hazard ratio (HR) 3·35, 95 per cent c.i. 2·16 to 5·19; P < 0·001), albumin level below 3·5 g/dl (HR 1·96, 1·22 to 3·15; P = 0·005) and largest tumour size greater than 5·0 cm (HR 1·81, 1·20 to 2·75; P = 0·005) were independent predictors of worse overall survival. CONCLUSION: Treatment strategies that include liver resection offer a survival benefit compared with non-surgical treatments for potentially resectable BCLC-B HCC.

RESUMO

BACKGROUND: This case represents the earliest appearance of de novo HCC after liver transplantation (OLT) compared with cases of previously reported literatures. CASE REPORT: A 45-year-old man underwent deceased donor OLT owing to decompensated liver cirrhosis. He had YMDD viral mutation and hepatitis B (HBV) and C (HCV) coinfection but no tumor was found in the liver on MRI before OLT. The donor was a healthy young female donor who was HCV and HBV negative. There was no tumor in the explant liver. After OLT, HCV RNA and hepatitis B surface antigen became undetectable with DNA-positive HBV. Nine months after OLT, a computed tomography (CT) scan was performed owing to abdominal pain, detecting a mass occupying the right lobe that depicted enhanced characteristics typical of HCC. The chest CT demonstrated metastatic lung nodules in the right basal lower lobe. Fluorescence in situ hybridization showed tumor cells from the recipient. CONCLUSIONS: To the best of our knowledge, this is the first report of de novo hepatocellular carcinoma that has emerged within a short period of undergoing OLT.

RESUMO

BACKGROUNDS: As for intrahepatic cholangiocarcinoma, the most frequent site of failure after curative intent resection is the liver. We identified the risk factors for locoregional recurrence after curative intent resection for intrahepatic cholangiocarcinoma. METHODS: Medical records of 115 patients treated with surgical resection alone for intrahepatic cholangiocarcinoma from November 2000 to December 2010 were retrospectively reviewed. Locoregional failure was defined as recurrence within 20 mm from resection margin or regional lymph node. Overall survival and locoregional recurrence rates were analyzed using Kaplan-Meier methods, and the prognostic factors were analyzed using Cox proportional hazards model. RESULTS: Median follow-up duration of surviving patients was 61 months (range 8-139). Sixty-six patients had recurrence, and 45 of 66 patients (68 %) had locoregional recurrence. The 5-year overall survival and locoregional control rates were 49.1 and 51.6 %, respectively. ≥ T2b disease and R1 resection were associated with locoregional recurrence in multivariate analysis. Patients were divided into two groups whether these risk factors exist or not. The 5-year locoregional control rates of low (no risk factor n = 64) and high (1 or 2 risk factors n = 51) risk groups were 62.5 and 34.7 %, respectively (P = 0.001). CONCLUSIONS: After curative intent resection, locoregional control and survival of patients with intrahepatic cholangiocarcinoma were far from satisfactory. Further studies are needed to evaluate the potential benefit of adjuvant locoregional treatment such as radiotherapy for patients with high-risk factors (≥ T2b disease or R1 resection).

RESUMO

BACKGROUND: Liver transplantation (LT) is the treatment of choice for hepatorenal syndrome (HRS). Recently, acute kidney injury (AKI) due to acute hepatitis A (HA) is increasing, but the outcome of LT is not well established. We investigated the outcomes of LT in patients with AKI due to acute HA compared with those of patients with HRS due to other causes. METHODS: We investigated the outcomes of LT in 20 patients with AKI associated with acute HA (HAV group) compared with 76 patients with hepatorenal syndrome (HRS) due to other causes (HRS group) at 3 Korea centers. RESULTS: Preoperative mean prothrombin time and serum creatinine level were higher in the HAV group than in the HRS group. But mean total bilirubin level was lower in the HAV group. There was no difference in Model for End-Stage Liver Disease scores. Post-transplantation patient and graft survival rates were similar between the 2 groups. More patients in the HAV group needed post-transplantation hemodialysis than in the HRS group (65.0% vs 38.2%; P = .043). However, post-transplantation estimated glomerular filtration rate was significantly higher in the HAV group after post-transplantation month 2 (P < .05). CONCLUSIONS: Peri-transplantation kidney function of the HAV group was poorer than that of HRS group. However, post-transplantation long-term renal outcome could be better in the HAV group.

RESUMO

BACKGROUND: The need for liver retransplantation (re-LT) has been increasing. Here we describe the outcome and technical aspects of re-LT during 25 years in a single major center. METHODS: We retrospectively reviewed patients who underwent LT from March 1988 to February 2013. Among 1,312 LTs during 25 years, 38 (2.9%) were re-LTs, including 28 adults (mean age 52.0 y) and 10 children (mean age 5.7 y). RESULTS: The most common indication was primary nonfunction in early re-LT and biliary complication in late re-LT. Preoperative major comorbidity was very common (81.6%). Among them, infection was the most frequent (52.6%). Living-donor re-LT constituted 21.1%. In operative technique, nonconventional methods were substantially performed, including high hilar dissection for hepatectomy (>50%), arterial anastomosis with the use of right gastroepiploic or jump graft (23.7%), and hepaticoenterostomy (60.5%). Several reanastomoses were needed in 10.5% for artery and 5.3% for duct. In adults and children, mean estimated blood losses were 9,541 mL and 977 mL, respectively. Mean operative times for adults and children were 508 and 432 minutes, respectively. In-hospital mortality was 35.7% in adults and 40.0% in children. The main cause of death was sepsis for both adults and children. Survival rates at 1 month and 1, 3, and 5 years were, respectively, 89.4%, 56.5%, 50.3%, and 50.3% in adults, and 70.0%, 60.0%, 60.0%, and 60.0% in children. CONCLUSIONS: Outcome of re-LT is poorer than primary LT regardless of the cause of graft failure. Therefore, more technical concerns need to be considered. We also need more efforts to control perioperative infections to improve survival after re-LT.

RESUMO

ABO blood group matching policy between donor and recipients is a chief element of organ allocation. However, O blood group donors may donate to all other blood group recipients, and ABO cross-transplantation has led to excessively long delays for blood group O. To investigate the consequence of this problem, we analyzed the recipients/donor rates according to ABO blood groups and cross-transplantation rates among them. Data about deceased donors and liver transplants performed in Korea from January 2008 to September 2012 were reviewed. The proportion of recipient to donor in the O blood group was lower compared to non-O groups (0.61). The percentage of O blood group transplantations in the Korean Network for Organ Sharing (KONOS) status 2B was lower than non-O groups (13.6%). In the status 1 and 2A groups, 44.4% of O blood group donors were allocated to non-O transplantations. Also, 30.7% O blood group donors were allocated to non-O transplantations in the status 2B groups. In conclusion, the ABO cross-transplantation in blood group O donors has led to lower transplantation rates of blood group O in status 1, 2A, and especially, the 2B group. Therefore, the KONOS allocation system should be re-evaluated to address this problem.

RESUMO

BACKGROUND: Since the introduction of lamivudine to treat chronic hepatitis B (CHB), the prevalence of lamivudine resistance is increasing among orthotopic liver transplant (OLT) candidates in Korea. OBJECTIVE: The purpose of this study was to evaluate the effect of pre-OLT lamivudine-resistance on the post-OLT prognosis of recipients. MATERIAL AND METHODS: Consecutive OLT recipient at a single tertiary care center (n = 8) between September 1999 and August 2009 were tested preoperatively for genotypic lamivudine resistance. We compared overall survival as well as incidences of graft failure, recurrent hepatitis, and hepatocellular carcinoma (HCC) between patients with (n = 35) versus without (n = 46) lamivudine-resistance. RESULTS: Mortality occurred in 2 resistant and 3 nonresistant individuals. The occurrences of graft failure, recurrent hepatitis, and HCC were 1, 2, and 2 cases, respectively, in the resistance group versus 2, 2, and 2 cases, respectively, in the nonresistance cohort. Univariate analysis showed no significant difference in survival, graft failure, HCC occurrence, and recurrent hepatitis. CONCLUSIONS: Our results indicated that pre-OLT lamivudine-resistance did not significantly affect the post-OLT prognosis. Thus, lamivudine-resistance may not be a barrier when considering OLT in patients with underlying CHB as a therapeutic modality, if it is treated with appropriate antiviral agents.

RESUMO

Thrombocytopenia (platelet < 60,000/mm(3)) and uncontrolled massive ascites (ascitic fluid > 1000 mL/d over 10 days) after liver transplantation (OLT), although uncommon, usually represent serious complications. Splenectomy is a useful treatment despite its many side effects. Recently, partial splenic artery embolization (PSAE) is considered to be a nonsurgical, less invasive treatment. In this study, we retrospectively reviewed the results of PSAE after OLT. Between October 2008 and February 2010, 11 patients underwent PSAE after OLT due to thrombocytopenia (n = 6) or refractory ascites (RA; n = 5). Six patients (54.5%) were males and 3 (27.3%) were children. The primary liver disease was virus-related liver cirrhosis (n = 6), biliary atresia (n = 3), fulminant hepatitis (n = 1), or alcoholic liver cirrhosis (n = 1). Seven grafts were from living and four from deceased donors. The major axial size of spleen was 12.1 to 23.4 cm and its average embolized volume, 76.4% (range = 70%-80%). As the result, the platelet count significantly increased after PSAE in all patients maintaining values greater than 100,000/mm(3) in four thrombocytopenic patients (66.7%). Cases of RA showed marked decreases after PSAE (100%). The follow-up was 6 to 28 months. After PSAE, patients experienced abdominal pain (n = 9, 81.8%), fever (n = 2, 18.2%), and abdominal distension (n = 2, 18.2%). However, there was no serious complication after PSAE such as splenic abscess, rupture, pancreatic infarction, sepsis, or death. In conclusion, PSAE was effective and safe and can be the choice for thrombocytopenia or RA related to hypersplenism after OLT.

RESUMO

Hepatitis B virus (HBV) recurrence following orthotopic liver transplantation (OLT) is generally preventable by prophylaxis with hepatitis B immunoglobulin (HBIG) and lamivudine (LAM). However, HBV recurrence sometimes develops despite prophylaxis. This study assessed posttransplant outcomes and identified predictors of HBV recurrence. We analyzed the outcomes of 209 consecutive patients positive for hepatitis B surface antigen who underwent OLT, who received either combination prophylaxis with HBIG and LAM (89.0%) or HBIG monoprophylaxis (11.0%). The median follow-up was 36.8 months (range, 1.0-84.4). Posttransplant HBV recurrence occurred in 22 patients (10.5%), including 13 patients with drug-resistant mutations. HBV recurrence was observed in six patients after hepatocellular carcinoma (HCC) recurrence. Independent predictors of HBV recurrence were recurrent HCC (p < 0.001), LAM therapy >1.5 years (p = 0.001) and high HBV DNA titers (> or =10(5) copies/mL) at OLT (p = 0.036). In conclusion, high viremia at OLT and prolonged exposure to LAM should be further stressed as main predictors of HBV recurrence.

RESUMO

BACKGROUND: We performed a modified right hepatectomy completely by laparoscopic techniques preserving the middle hepatic vein (MHV) branches in adult-to-adult living donor liver transplantation (LDLT). PATIENTS AND METHODS: Two young women (24 and 25 years old) volunteered to be live donors for their parents who had hepatocellular carcinomas. As the donors expressed concerns about scarring, we performed a laparoscopic procedure using a hand port device. Mobilization of the right liver and the hepatic parenchymal transection were performed under pneumoperitoneum. Parenchymal transection was performed using a laparoscopic ultrasonic aspirator without the Pringle maneuver. During parenchymal transection, major MHV branches >5 mm were preserved using Hem-o-lock clips. The graft was extracted through the hand port site. On the back table, the 3 MHV branches were reconstructed using an artificial vascular graft. The livers were transplanted without complications. RESULTS: The operative times for the donors were 765 and 898 minutes. The donors did not require transfusions or reoperation; they were discharged on postoperative days 10 and 14 with normal liver functions. CONCLUSION: A hepatectomy performed completely by laparoscopic techniques for a right graft with preservation of the MHV branches was technically feasible.
