Anouti A, Al Hariri M, VanWagner LB, Lee WM, Mufti A, Pedersen M, Shah J, Hanish S, Vagefi PA, Cotter TG, Patel MS. Early Graft Failure After Living-Donor Liver Transplant. Dig Dis Sci 2024; 69:1488-1495. [PMID: 38381224 DOI: 10.1007/s10620-024-08280-5] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/29/2023] [Accepted: 01/04/2024] [Indexed: 02/22/2024]
Abstract
BACKGROUND Living-donor liver transplantation (LDLT) has been increasing in the USA. While data exist on longer-term patient and graft outcomes, a contemporary analysis of short-term outcomes is needed. AIM Evaluate short-term (30-day) graft failure rates and identify predictors associated with these outcomes. METHODS Adult (≥ 18) LDLT recipients from 01/2004 to 12/2021 were analyzed from the United States Scientific Registry of Transplant Recipients. Graft status at 30 days was assessed with graft failure defined as retransplantation or death. Comparison of continuous and categorical variables was performed and a multivariable logistic regression was used to identify risk factors of early graft failure. RESULTS During the study period, 4544 LDLTs were performed with a graft failure rate of 3.4% (155) at 30 days. Grafts from male donors (aOR: 0.63, CI 0.44-0.89), right lobe grafts (aOR: 0.40, CI 0.27-0.61), recipients aged > 60 years (aOR: 0.52, CI 0.32-0.86), and higher recipient albumin (aOR: 0.73, CI 0.57-0.93) were associated with superior early graft outcomes, whereas Asian recipient race (vs. White; aOR: 3.75, CI 1.98-7.10) and a history of recipient PVT (aOR: 2.7, CI 1.52-4.78) were associated with inferior outcomes. LDLTs performed during the most recent 2016-2021 period (compared to 2004-2009 and 2010-2015) resulted in significantly superior outcomes (aOR: 0.45, p < 0.001). CONCLUSION Our study demonstrates that while short-term adult LDLT graft failure is uncommon, there are opportunities for optimizing outcomes by prioritizing right lobe donation, improving candidate nutritional status, and careful pre-transplant risk assessment of candidates with known PVT. Notably, a period effect exists whereby increased LDLT experience in the most recent era correlated with improved outcomes.

[PMID: 38299260 DOI: 10.1002/jpn3.12145] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/31/2023] [Revised: 12/15/2023] [Accepted: 01/04/2024] [Indexed: 02/02/2024]
Abstract
OBJECTIVES To analyse the donor characteristics and understand the sociocultural and familial aspects of the decision to donate for living donor liver transplant. METHODS This is a retrospective study done in the Department of Pediatric Gastroenterology and Hepatology of a liver transplant centre. We enrolled the consenting donors of pediatric liver transplantation between January 2020 and January 2022. The study was conducted through an anonymized questionnaire which was drafted in a multiple-choice format. The questionnaire had three domains having questions pertaining to demographic details, donor characteristics and sociofamilial aspects of the decision-making process. RESULTS The study cohort consisted of 50 donors, 23 males (46%) and 27 females (54%), with the mean age being 31.8 ± 5.6 years. Parent-to-child was the most frequent relationship (n = 39, 78%). More than half of our donors had annual income <2.5 lakh/annum or <3500 USD (n = 27, 54%). Twenty-six (52%) responders had >4 members in their family; 62% were residing in urban areas and 52% of the donors were graduates. The main source of information regarding the feasibility of living donor liver transplantation was primary physicians in 46%. Financial management was the main hurdle in 72%. Majority (74%) denied any effect on their marital relationship and 6% of donors thought that the degree of information provided to them before the transplantation regarding donation was insufficient. CONCLUSION Our study serves as an essential tool for health professionals to provide sufficient support to the donor. Clinical outcomes and cost must be part of the discussion between caregivers, health professionals and fund contributors.

Abstract
PURPOSE This meta-analysis aimed to investigate the acceptability of donor remnant liver volume (RLV) to total liver volume (TLV) ratio (RLV/TLV) being <30% as safe in living donor liver transplantations (LDLTs). METHODS Online databases were searched from January 2000 to June 2022. Pooled odds ratios (ORs) and standardized mean differences (SMDs) with 95% confidence intervals (CIs) were calculated using fixed- or random-effects model. RESULTS One prospective and seven retrospective studies comprising 1935 patients (164 RLV/TLV <30% vs. 1771 RLV/TLV ≥30%) were included. Overall (OR = 1.82; 95% CI [1.24, 2.67]; p = .002) and minor (OR = 1.88; 95% CI [1.23, 2.88]; p = .004) morbidities were significantly lower in the RLV/TLV ≥30% group than in the RLV/TLV <30% group (OR = 1.82; 95% CI [1.24, 2.67]; p = .002). No significant differences were noted in the major morbidity, biliary complications, and hepatic dysfunction. Peak levels of bilirubin (SMD = .50; 95% CI [.07, .93]; p = .02) and international normalized ratio (SMD = .68; 95% CI [.04, 1.32]; p = .04) were significantly lower in the RLV/TLV ≥ 30% group than in the RLV/TLV <30% group. No significant differences were noted in the peak alanine transferase and aspartate transaminase levels and hospital stay. CONCLUSIONS Considering the safety of the donor as the top priority, the eligibility of a potential liver donor in LDLT whose RLV/TLV is expected to be <30% should not be accepted.

Abstract
PURPOSE The present study aims to evaluate the correlation of two-dimensional shear wave elastography results with histopathological findings performed simultaneously with liver biopsy (LB) in healthy liver transplant donors. METHODS A total of 53 living donors, 35 male and 18 female, were included in this prospective, observational, single-center study. Patients with abnormal liver function tests were not included in our study. Hepatosteatosis, fibrosis, and inflammation were evaluated with the Fatty Liver Inhibition of Progression and Steatosis, Activity, and Fibrosis algorithm of donor LB. RESULTS The mean age of the donors was 33.04 ± 9.07 years and the mean body mass index was 23.41 ± 6.23 kg/m2. The mean elastography kilo pascal (kPA) value of all donors was determined as 6.03 ± 2.32 kPa. The mean LB activity scores of the donors were found to be 1.64 ± 1.18 and ranged from 0 to 5. There was no significant correlation between elastography kPa value and pathologic activity score, steatosis score, balloon degeneration, and inflammation grade fibrosis scores (P > .05). CONCLUSION Shear wave elastography measurements showed that the predictive power of pathologic findings in donor LB was not sufficient.

Abstract
Recent modifications in organ allocation policies and increases in chronic liver diseases may have resulted in important changes in living donor liver transplantation (LDLT) in the United States. We examined the trends, outcomes, and factors associated with outcomes in adult LDLT. United Network for Organ Sharing data on 2566 adult LDLT recipients who received transplants from January 1, 2010, through December 31, 2019, were analyzed. LDLT graft and patient survival rates were compared with propensity score-matched deceased donor liver transplantation recipients by the Kaplan-Meier curve estimator. The association between preceding LDLT frequency and subsequent outcomes were assessed by Cox proportional hazards mixed effects modeling. After a stable annual frequency of LDLTs from 2010 to 2014 (~200 per year), the number of LDLTs doubled to 440 in 2019. The 1-year and 5-year graft survival rates for LDLT recipients were 88.4% and 78.1%, respectively, compared with 92.5% and 80.7% in the propensity score-matched donation after brain death recipients (P = 0.005), respectively. Older donor age and recipient diabetes mellitus and life support requirement were significantly associated with graft failure among LDLT recipients (P values <0.05). Average preceding LDLT frequencies of <3 per year, 3 to 20 per year, and >20 per year resulted in 1-year graft survival rates of 82%, 88% to 89%, and 93%, respectively (P values <0.05). There were 3 living donor deaths (0.12%). The frequency of LDLTs has doubled during the past decade, with good outcomes and acceptable donor safety profiles. However, there appear to be varying threshold transplant frequencies (volume/unit time) associated with acceptable (88%-89%) and aspirational (93%) 1-year graft survival rates. These data should be reassuring and encourage LDLT practice as efforts continue to expand the donor pool.

Abstract
OBJECTIVES The shortage of deceased donor organs is a limiting factor in transplant. The growing discrepancy between the wait list demand versus the supply of deceased donor organs has created an incentive for consideration of living donor liver transplant as an alternative. Here, we describe our evaluation process and donor complications. MATERIALS AND METHODS Since 1988, we have performed 659 (449 living donor and 210 deceased donor) liver transplants. The most important evaluation criteria is the relationship between donor and recipient, and we require thatthe donor must be related to the recipient. The evaluation protocol has 5 stages. Donor complications were defined as simple, moderate, and severe. RESULTS We retrospectively investigated data for 1387 candidates, and 938 (67.7%) were rejected; subsequently, 449 living donor liver transplants were performed. There were no complications in 398 of the donors (88.7%). Total complication rate was 11.3%. Simple complications were seen in 31 patients (6.9%). Moderate complications were seen in 19 patients (4.2%). We had only 1 severe complication, ie, organ failure from unspecified liver necrosis, which resulted in death. CONCLUSIONS The relationship between donor and recipient and donor safety should be the primary focus for living donor liver transplant. Donor selection should be made carefully to minimize complications and provide adequately functional grafts.

Abstract
Two-thirds partial hepatectomy (PHx) was performed in rats, and the differences in effects between S-allylcysteine (SAC) and other sulfur-containing compounds on regeneration of the remaining liver and restoration of the injury were examined. Three days after two-thirds PHx, rats treated with 300 mg/kg/d, per os (p.o.) SAC showed a 1.2-fold increase in liver weight per 100 g body weight compared with saline-treated controls. In contrast, S-methylcysteine (SMC) (300 mg/kg/d, p.o.) or cysteine (Cys) (300 mg/kg/d, p.o.) did not have a regeneration-promoting effect. In the comparison with control rats, the regenerating liver of SAC-treated rats showed a significantly higher 5-bromo-2'-deoxyuridine labeling index on day 1. In contrast, serum alanine aminotransferase activity, which increases following PHx, was significantly inhibited by SAC and SMC (but not Cys) on day 1 after two-thirds PHx. In addition, SAC induced increases in insulin-like growth factor (IGF)-1 and its receptor mRNA expressions at 1 h after two-thirds PHx, and it increased phosphorylation of extracellular signal-regulated kinase (ERK)2 and Akt at 3 h after two-thirds PHx without affecting serum growth hormone levels. These results demonstrate that SAC is a mitogenic effector of normal remnant liver and promotes recuperation of liver function after two-thirds PHx. Moreover, SAC-induced proliferative effects are mediated via increased mRNA expressions of IGF-1 and its receptor and subsequent phosphorylation of ERK2 and Akt.

Abstract
The present study reports on the experience at Jiangxi Provincial People's Hospital (Nanchang, China) with liver transplantation in adults using pediatric donor livers, including indications, technique and results. A total of three cases of liver transplantation performed between April 2008 and May 2016 were retrospectively reviewed. Liver procurement and trimming, recipient selection, surgical tips, prevention and treatment of small-for-size syndrome, selection of immunosuppressive regimens, prevention and treatment of vascular complications and anticoagulant therapy were discussed. The three pediatric donors were 8, 8 and 10 years old. The three recipients were confirmed to have primary liver cancer. In recipient 1 (female; age, 39 years), jaundice persisted in the recipient after the liver transplantation. A reduced dose of FK506 was then given to gradually decrease the total bilirubin level to the normal range. Recipient 1 recovered and was discharged from hospital; however, the patient died of liver cancer recurrence and bone metastasis 6 years post-transplantation. In recipient 2 (male; age, 56 years), the recipient experienced sudden abdominal distension on postoperative day 7. The patient's clotting time was prolonged and the transaminase level was sharply increased, peaking on day 9. The patient was suspected of having small-for-size syndrome and was treated symptomatically. The patient experienced a significant improvement in symptoms on postoperative day 13 and regular postoperative follow-ups were performed until now and the patient is now in remission. In recipient 3 (male; age, 48 years), the recipient recovered well and the liver function returned to normal on postoperative day 3. The patient was discharged from hospital and has been in remission thus far. Adult liver transplantations from pediatric donors are feasible treatments. Systematic donor and recipient assessments, sound surgical skills and optimal postoperative treatments are essential for success in the transplantation of livers from pediatric donors into adult recipients. Considering the condition of the donor liver, the selection of recipients and appropriate surgical methods are particularly important in these cases.

Abstract
Background We examine how residual liver volume (RLV) and hepatic steatosis (HS) of living liver donors affect the regeneration process and clinical outcomes. Material/Methods We longitudinally studied 58 donors who underwent right-lobe hepatectomy during the period February 2014 to February 2015 at a single medical institution. The patients were classified based on RLV (30–35%, 35–40%, 40–50%) subgroups and HS (<10%, 10–30%, 30–50%) subgroups. Clinical parameters such as clinical outcome, liver volumetric recovery (LVR,%) rate and remnant left-liver (RLL,%) growth rate were collected for analysis. Results The clinical features of postoperative peak total bilirubin (p=.024) were significant in the 3 RLV subgroups. Body mass index (p=.017), preoperative alanine transaminase (p<.001), and pleural effusion (p=.038) were significant in the 3 HS subgroups. The LVR rate and RLL growth rate equations showed significant variation in regeneration among the 3 RLV subgroups. The LVR rate and RLL growth rate equations did not show significant variation in regeneration among the 3 HS subgroups. Conclusions Hyperbilirubinemia was a risk factor in the small-RLV group, and a large amount of pleural effusion was a risk factor in the steatosis 30–50% group. Hepatic steatosis subgroups did not show significantly different degrees of regeneration. The safety of living donors was a major concern while we compiled the extended living-donor criteria presented in this paper.

Abstract
Three-dimensional (3D) printing has been used to support organ transplantations. However, whether it helps remains unclear. This study aimed to present and assess the application of 3D-printed liver models in pediatric living donor liver transplantation (LDLT). The 3D images were printed to touchable liver models with transparent liver parenchyma, specifically colored hepatic vessels, and biliary structures. A total of 30 consecutive recipients were enrolled in the study: 10 were operated on with the support of 3D printing (3D-printing group) and 20 (control group) were operated on without it. Detailed photographs and data of the cases in the 3D-printing group were presented. One patient underwent auxiliary partial orthotopic liver transplantation using the left lobe graft, in which the abdominal cavity model was also printed to test whether the planned graft fit the recipient's abdominal cavity. The 3D-printed models facilitated surgical planning and procedures, particularly in the management of hepatic veins and in the prevention of large-for-size syndrome. The operative time of donors in the 3D-printing group was significantly shorter compared with the control group (2.3 ± 0.4 versus 3.0 ± 0.4 hours; P < 0.001). Inpatient costs for donors in the 3D-printing group were 17.1% lower than those in the control group (34.6 ± 6.6 versus 41.7 ± 10.4 thousand ¥; P = 0.03). In conclusion, in small infants and complicated pediatric LDLT patients, 3D-printed models can help minimize the risk of large-for-size syndrome and graft reduction. The 3D-printed models may be conducive to liver graft procurement and intraoperative assistance in pediatric LDLT.

Abstract
The concept of dual-graft liver transplantation was introduced to overcome the discrepancy between liver transplantation demand and liver donation. Dual-graft transplantation also mitigates cumulative family risk by decreasing individual donor risk through minimization of the resected liver volume from each donor. Here, we describe the first two cases performed in Saudi Arabia wherein a dual-graft living donor liver transplantation was facilitated by the use of one left lobe graft and one left lateral segment in both cases. These are the first two cases of dual-graft liver transplantation reported from Saudi Arabia and the Middle East. SIMILAR CASES PUBLISHED: Nine on the same subject in other parts of the world (Korea, Japan, Germany, China, and Brazil).

Abstract
OBJECTIVES We investigated whether chronological changes in portal flow and clinical factors play a role in the liver regeneration (LR) process after right donor-hepatectomy. MATERIALS AND METHODS Participants in this prospective study comprised 58 donors who underwent right donor-hepatectomy during the period February 2014 to February 2015 at a single medical institution. LR was estimated using two equations: remnant left liver (RLL) growth (%) and liver volumetric recovery (LVR) (%). Donors were classified into an excellent regeneration (ER) group or a moderate regeneration (MR) group based on how their LR on postoperative day 7 compared to the median value. RESULTS Multivariate analysis revealed that low residual liver volume (OR = .569, 95% CI: .367- .882) and high portal venous velocity in the immediate postoperative period (OR = 1.220, 95% CI: 1.001-1.488) were significant predictors of LR using the RLL growth equation; high portal venous velocity in the immediate postoperative period (OR = 1.325, 95% CI: 1.081-1.622) was a significant predictor of LR using the LVR equation. Based on the two equations, long-term LR was significantly greater in the ER group than in the MR group (p < .001). CONCLUSION Portal venous velocity in the immediate postoperative period was an important factor in LR. The critical time for short-term LR is postoperative day 7; it is associated with long-term LR in donor-hepatectomy.

Abstract
This study evaluated multi-detector computed tomography (MDCT) scans performed on potential living donors for adult-to-adult liver transplantation (LDLT), with the aim of identifying significant findings that could be used to exclude potential transplantation donors. We retrospectively reviewed the medical records of 151 consecutive potential adult donors for LDLT from May 2007 to January 2015. Liver parenchyma steatosis, focal hepatic mass or intraabdominal malignancy, vascular variations, and donor liver volume were evaluated via MDCT. Grounds for excluding potential donors were also recorded and analyzed. Of the 151 potential donors, nine (6.0%) had moderate to severe fatty liver, 37 (24.5%) had hepatic arterial variants, 22 (14.6%) had significant portal venous variants, and more than half were found to have right accessory inferior hepatic vein. No intraabdominal malignancies were found. Eighty-eight potential donors were rejected, with the most common cause being insufficient recipient volume or remnant donor volume (47.7%), moderate to severe parenchymal steatosis (10.2%), and recipient expiration prior to transplantation (8.0%). An additional 16 potential donors were excluded by the surgical team due to the complexity of their portal venous variations. The rate of exclusion by pre-transplant imaging evaluation with MDCT was 33.8%. MDCT can provide accurate quantification of donor liver volume and steatosis severity along with precise demonstration of vascular variants, which are crucial for the preoperative evaluation of LDLT. However, MDCT may be ineffective for evaluating the biliary system without hepatobiliary-excreted contrast agent and has the disadvantage of ionizing radiation.

Impact of Portal Hemodynamic Changes in Partial Liver Grafts on Short-Term Graft Regeneration in Living Donor Liver Transplantation. Transplant Proc 2017; 48:2747-2755. [PMID: 27788812 DOI: 10.1016/j.transproceed.2016.06.053] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/24/2016] [Revised: 05/20/2016] [Accepted: 06/22/2016] [Indexed: 02/07/2023]
Abstract
BACKGROUND Regeneration of partial liver grafts is critical for successful living donor liver transplantation (LDLT), especially in adult recipients. The purpose of this study was to investigate the intraoperative hemodynamic changes in partial liver grafts and characterize their potential impact on post-transplant liver regeneration in LDLT. METHODS We examined the portal venous flow (PVF) and hepatic arterial flow (HAF) to partial liver grafts by means of ultrasonic transit time flowmeter of donors immediately before graft retrieval and of the corresponding recipients after vascular reconstruction in 48 LDLT cases. We evaluated post-transplant liver regeneration according to the changes in graft liver volume between the time of transplantation and the 7th post-transplant day. RESULTS There was a significant increase in PVF to the partial liver grafts in recipients (rPVF) compared with that in donors. In contrast, graft HAF in recipients significantly decreased compared with that in donors. The rPVF inversely correlated with graft weight (GW)-recipient body weight ratio (GRWR), whereas HAF volume showed no significant correlation. The rPVF/GW positively correlated with the rate of liver regeneration (GRR), which inversely correlated with GRWR. The rPVF/GW was significantly higher, and GRR tended to be larger in the small graft group than in the non-small graft group. CONCLUSIONS Intraoperative portal hemodynamic changes in partial liver grafts strongly affect their post-transplant regeneration. In particular, in small liver grafts, an immediate and remarkable increase in graft PVF may contribute to rapid liver regeneration after LDLT if the increased PVF remains within a safe range.

Abstract
AIM to estimate the effect of decompressive stented drainage of biliary anastomosis on incidence of biliary complications. MATERIAL AND METHODS 294 patients aged from 5 months to 61 years (mean 13.8±0.81) were enrolled. They underwent liver fragments transplantation in the Department of Liver Transplantation of Petrovsky Russian Research Center of Surgery for the period from March 1997 to January 2016. Decompressive stented drainage tubes were used in 28 (9.5%) patients. Reconstruction without drainage was applied in 266 (90.5%) cases. In the group of biliobiliary reconstruction drainage was used in 18 out of 89 cases (20.2%), in the group of biliodigestive reconstruction - in 10 out of 202 cases (4.9%). Incidence of specific biliary complications was assessed. RESULTS There was significant direct correlation of stented drainage of biliodigestive anastomosis with various biliary complications including bile leakage (r= -0,1253; p=0.06), obturation of anastomosis (r=0.045; p=0.501), stricture of anastomosis (r= -0.0665; p=0.320), other strictures of intrahepatic bile ducts (r= -0.0291; p=0.664), hepatolithiasis (r=0.0857; p=0.199). However significant direct correation was observed between stented drainage and incidence of intrahepatic bile ducts strictures (r=0.2117; p=0.046) and anastomosis obturation (r=0.2330; p=0.028) in case of biliobiliary reconstruction. Significant correation with other biliary complications was absent (p>0.05). CONCLUSION Unconstrained stented drainage during primary biliary reconstruction is associated with increased incidence of biliary complications and should not be indicated routinely. Clear need for drainage should be determined in further investigations.

Abstract
This article outlines psychosocial and ethical issues to be considered when evaluating potential living organ donors. Six types of living donors are described: genetically related, emotionally related, “Good Samaritan” (both directed and nondirected), vendors, and organ exchangers. The primary domains to be assessed in the psychosocial evaluation are informed consent, motivation for donating and the decision-making process, adequacy of support (financial and social), behavioral and psychological health, and the donor-recipient relationship. Obstacles to the evaluation process include impression management, overt deception, minimization of behavioral risk factors, and cultural and language differences between the donor and the evaluator. Ethical concerns, such as the right to donate, donor autonomy, freedom from coercion, nonmaleficence and beneficence in donor selection, conflicts of interest, “reasonable” risks to donors, and recipient decision making are also explored. To fully evaluate living organ donation, studying psychosocial as well as medical outcomes is crucial.

Abstract
We enumerate the broad range of anesthetic considerations that affect the outcome of patients undergoing laparoscopic liver resection. Key elements for excellent outcomes after laparoscopic liver resection are careful patient selection and risk stratification, appropriate monitoring, techniques to reduce blood loss and transfusion, and active recovery management. Although some of these key elements are the same for open liver operation, there are specific anesthetic considerations of which both the surgical and anesthesia teams must be aware to achieve optimal patient outcomes after laparoscopic liver resection. While unique advantages of laparoscopic liver resection typically include decreased intraoperative bleeding, transfusion requirements, and a lower incidence of postoperative ascites, specific challenges include management of the complicated interplay between low-volume anesthesia and increased intraabdominal pressure due to pneumoperitoneum, with additional considerations regarding circulatory support to treat acute blood loss with need for emergent conversion in some cases. This article will address in detail the preoperative, intraoperative, and postoperative anesthetic considerations for patients undergoing laparoscopic liver resection that both the surgical and anesthesia team should be aware of to optimize outcomes.

Abstract
OBJECTIVES The purpose of the study was to determine the diagnostic value of computed tomography densitometry in the quantification of hepatosteatosis. MATERIALS AND METHODS Fifty-one potential liver donors, ranging in age from 19 to 52 years (mean age: 32.4 years ± 10.2), participated in the study. The mean hepatic attenuation and mean splenic attenuation were determined using regions of interest measurements. The difference between the mean hepatic attenuation and mean splenic attenuation (or liver attenuation index), with liver attenuation index = mean hepatic attenuation - mean splenic attenuation were calculated. Computed tomography densitometric parameters were correlated with histopathologic results. RESULTS From the histopathologic analysis, the degree of macrovesicular hepatosteatosis was 0% to 8% (mean: 1.1% ± 2%). Seven donors (13.7%) had a degree of macrovesicular steatosis of > 5%, and 12 donors (23.5%) had ≥ 2%. Of the 29 normal donors with histopathologic verification, computed tomography densitometry predicted ≤ 5% of the hepatosteatosis in 27 donors, and ≤ 2% hepatosteatosis in 2 subjects. The liver attenuation index was significantly correlated to the histopathologic results. The mathematical relation between liver attenuation index and the degree of histopathologic hepatosteatosis was calculated using the least-squares methods, which provided quadratic polynomials. CONCLUSIONS Computed tomography densitometry is a rapid, robust, noninvasive technique for the assessment of hepatosteatosis. When used in conjunction with clinically stable reference measurements of spleen, the density measurements of liver correctly predicted the presence of fatty infiltration with significant sensitivity (77%) and specificity (75%). This technique, which was refined during the course of our liver transplant program, minimizes the need for highly invasive percutaneous liver biopsies.

Abstract
AIM: To investigate middle hepatic vein (MHV) management in adult living donor liver transplantation and safer remnant volumes (RV).
METHODS: There were 59 grafts with and 12 grafts without MHV (including 4 with MHV-5/8 reconstructions). All donors underwent our five-step protocol evaluation containing a preoperative protocol liver biopsy Congestive vs non-congestive RV, remnant-volume-body-weight ratios (RVBWR) and postoperative outcomes were evaluated in 71 right graft living donors. Dominant vs non-dominant MHV anatomy in total liver volume (d-MHV/TLV vs nd-MHV/TLV) was constellated with large/small congestion volumes (CV-index). Small for size (SFS) and non-SFS remnant considerations were based on standard cut-off- RVBWR and RV/TLV. Non-congestive RVBWR was based on non-congestive RV.
RESULTS: MHV and non-MHV remnants showed no significant differences in RV, RV/TLV, RVBWR, total bilirubin, or INR. SFS-remnants with RV/TLV < 30% and non-SFS-remnants with RV/TLV ≥ 30% showed no significant differences either. RV and RVBWR for non-MHV (n = 59) and MHV-containing (n = 12) remnants were 550 ± 95 mL and 0.79 ± 0.1 mL vs 568 ± 97 mL and 0.79 ± 0.13, respectively (P = 0.423 and P = 0.919. Mean left RV/TLV was 35.8% ± 3.9%. Non-MHV (n = 59) and MHV-containing (n = 12) remnants (34.1% ± 3% vs 36% ± 4% respectively, P = 0.148. Eight SFS-remnants with RVBWR < 0.65 had a significantly smaller RV/TLV than 63 non-SFS-remnants with RVBWR ≥ 0.65 [SFS: RV/TLV 32.4% (range: 28%-35.7%) vs non-SFS: RV/TLV 36.2% (range: 26.1%-45.5%), P < 0.009. Six SFS-remnants with RV/TLV < 30% had significantly smaller RVBWR than 65 non-SFS-remnants with RV/TLV ≥ 30% (0.65 (range: 0.6-0.7) vs 0.8 (range: 0.6-1.27), P < 0.01. Two (2.8%) donors developed reversible liver failure. RVBWR and RV/TLV were concordant in 25%-33% of SFS and in 92%-94% of non-SFS remnants. MHV management options including complete MHV vs MHV-4A selective retention were necessary in n = 12 vs n = 2 remnants based on particularly risky congestive and non-congestive volume constellations.
CONCLUSION: MHV procurement should consider individual remnant congestive- and non-congestive volume components and anatomy characteristics, RVBWR-RV/TLV constellation enables the identification of marginally small remnants.

Abstract
We report our experience with potential donors for living donor liver transplantation (LDLT), which is the first report from an area where there is no legalized deceased donation program. This is a single center retrospective analysis of potential living donors (n = 1004) between May 2004 and December 2012. This report focuses on the analysis of causes, duration, cost, and various implications of donor exclusion (n = 792). Most of the transplant candidates (82.3%) had an experience with more than one excluded donor (median = 3). Some recipients travelled abroad for a deceased donor transplant (n = 12) and some died before finding a suitable donor (n = 14). The evaluation of an excluded donor is a time-consuming process (median = 3 d, range 1 d to 47 d). It is also a costly process with a median cost of approximately 70 USD (range 35 USD to 885 USD). From these results, living donor exclusion has negative implications on the patients and transplant program with ethical dilemmas and an economic impact. Many strategies are adopted by other centers to expand the donor pool; however, they are not all applicable in our locality. We conclude that an active legalized deceased donor transplantation program is necessary to overcome the shortage of available liver grafts in Egypt.

[PMID: 25409662 PMCID: PMC4282230 DOI: 10.14366/usg.14038] [Citation(s) in RCA: 6] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/25/2014] [Revised: 09/19/2014] [Accepted: 10/04/2014] [Indexed: 12/15/2022] Open
Abstract
Purpose: The purpose of this study was to investigate the value of UltraFast Doppler ultrasonography (US) for evaluating hepatic vessels in liver recipients. Methods: Thirty-nine liver Doppler US sessions were conducted in 20 liver recipients. Each session consisted of UltraFast and conventional liver Doppler US in a random order. We compared the velocities and phasicities of the hepatic vessels, duration of each Doppler study, occurrence of technical failures, and differences in clinical decisions. Results: The velocities and resistive index values of hepatic vessels showed a strong positive correlation between the two Doppler studies (mean R=0.806; range, 0.710 to 0.924). The phasicities of the hepatic vessels were the same in both Doppler US exams. With respect to the duration of the Doppler US exam, there was no significant difference between the UltraFast (251±99 seconds) and conventional (231±117 seconds) Doppler studies (P=0.306). In five poor breath-holders, in whom the duration of conventional Doppler US was longer, UltraFast Doppler US (272±157 seconds) required a shorter time than conventional Doppler US (381±133 seconds; P=0.005). There was no difference between the two techniques with respect to technical failures and clinical decisions. Conclusion: UltraFast Doppler US is clinically equivalent to conventional Doppler US with advantages for poor breath-holders during the post-liver transplantation work-up.

Venous Outflow Reconstruction in Adult Living Donor Liver Transplant: Outcome of a Policy for Right Lobe Grafts without the Middle Hepatic Vein. HPB SURGERY : A WORLD JOURNAL OF HEPATIC, PANCREATIC AND BILIARY SURGERY 2013; 2013:280857. [PMID: 24489434 PMCID: PMC3892747 DOI: 10.1155/2013/280857] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 07/10/2013] [Revised: 10/27/2013] [Accepted: 10/29/2013] [Indexed: 12/14/2022]
Abstract
Introduction. The difficulty and challenge of recovering a right lobe graft without MHV drainage is reconstructing the outflow tract of the hepatic veins. With the inclusion or the reconstruction of the MHV, early graft function is satisfactory. The inclusion of the MHV or not in the donor's right lobectomy should be based on sound criteria to provide adequate functional liver mass for recipient, while keeping risk to donor to the minimum. Objective. Reviewing the results of a policy for right lobe grafts transplant without MHV and analyzing methods of venous reconstruction related to outcome. Materials and Methods. We have two groups Group A (with more than one HV anast.) (n = 16) and Group B (single HV anast.) (n = 24). Both groups were compared regarding indications for reconstruction, complications, and operative details and outcomes, besides describing different modalities used for venous reconstruction. Results. Significant increase in operative details time in Group A. When comparison came to complications and outcomes in terms of laboratory findings and overall hospital stay, there were no significant differences. Three-month and one-year survival were better in Group A. Conclusion. Adult LDLT is safely achieved with better outcome to recipients and donors by recovering the right lobe without MHV, provided that significant MHV tributaries (segments V, VIII more than 5 mm) are reconstructed, and any accessory considerable inferior right hepatic veins (IRHVs) or superficial RHVs are anastomosed.

Abstract
CONTEXT Living donor liver transplantation has become an alternative to reduce the lack of organ donation. OBJECTIVE To identify factors predictive of early graft loss in the first 3 months after living donor liver transplantation. METHODS Seventy-eight adults submitted to living donor liver transplantation were divided into group I with 62 (79.5%) patients with graft survival longer than 3 months, and group II with 16 (20.5%) patients who died and/or showed graft failure within 3 months after liver transplantation. The variables analyzed were gender, age, etiology of liver disease, Child-Pugh classification, model of end-stage liver disease (MELD score), pretransplantation serum sodium level, and graft weight-to-recipient body weight (GRBW) ratio. The GRBW ratio was categorized into < 0.8 and MELD score into >18. The chi-square test, Student t-test and uni- and multivariate analysis were used for the evaluation of risk factors for early graft loss. RESULTS MELD score <18 (P<0.001) and serum sodium level > 135 mEq/L (P = 0.03) were higher in group II than in group I. In the multivariate analysis MELD scores > 18 (P<0.001) and GRBW ratios < 0.8 (P<0.04) were significant. CONCLUSIONS MELD scores >18 and GRBW < 0.8 ratios are associated with higher probability of graft failure after living donor liver transplantation.

Hilmi IA, Planinsic RM. Live liver donors: Are they at a higher risk for post-operative thrombotic complications? World J Transplant 2012; 2:1-4. [PMID: 24175189 PMCID: PMC3812926 DOI: 10.5500/wjt.v2.i1.1] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/16/2011] [Revised: 12/20/2011] [Accepted: 02/23/2012] [Indexed: 02/05/2023] Open
Abstract
Live liver donor transplantation to adult recipients is becoming a common practice, increasing the organ pool and providing an alternative to whole cadaveric liver transplantation. These patients are healthy adults without serious medical conditions and typically have normal coagulation profiles preoperatively. Right hepatic lobectomy is usually performed for adult recipients, while left hepatic lobectomy is performed for pediatric recipients. Removal of the whole right lobe from the donors may expose theses patients to multiple intraoperative and postoperative complications. Hypercoagulability has been identified as a serious complication which leads to thromboembolic phenomena with potential fatal consequences. The primary aim of this review is to look at possible changes in post-operative coagulation dynamics that may increase the risk for development of thromboembolic complications in live liver donors. In this article, we stress the importance of addressing the issue that conventional clotting tests (PT, INR, PTT) are unable to detect a hypercoagulable state, and therefore, we should examining alternative laboratory tests to improve diagnosis and early detection of thrombotic complications. Measurement of natural anticoagulant/procoagulant biomarkers combined with conventional coagulation studies and thromboelastography offers a more accurate assessment of coagulation disorders. This allows earlier diagnosis, permitting appropriate intervention sooner, hence avoiding potential morbidity and mortality. Biomarkers that may be evaluated include, but are not limited to: protein C, soluble P-selectin, antithrombin III, thrombin-antithrombin complex, and thrombin generation complex.

Three-dimensional computed tomography analysis of venous collaterals between the middle hepatic vein tributaries and the right hepatic vein in the donor remnant right lobe: report of a case. Surg Today 2011; 41:1266-9.

Abstract
We report how three-dimensional computed tomography (3D-CT) showed the development of obvious venous collaterals between the middle hepatic vein (MHV) tributaries and the right hepatic vein (RHV) in the remnant right lobe of a donor liver. The donor was a healthy 34-year-old man who donated the left lobe of his liver with the MHV. The 3D-CT calculated that the total drainage of the MHV tributaries was 413 ml, corresponding to 59% of the total remnant liver. The congestion calculated by 3D-CT decreased from 286 ml on postoperative day (POD) 7 to 28 ml on POD 35, corresponding to 36% and 3% of the total remnant liver, respectively. The donor was discharged from hospital with almost normal liver function, and 3D-CT analysis on POD 35 detected obvious venous collaterals between the MHV tributaries and the RHV. These findings suggest that reconstruction of the MHV tributaries in the donor remnant right lobe may not be necessary.

Abstract
PURPOSE To investigate the correlation between the graft volume calculated by 64-detector-row spiral computed tomography (CT) and the graft weight measured during the living donor liver transplantation (LDLT) operation, and try to get an equation to help determine the possible weight of graft before operation. METHODS 23 donors with left lateral lobe LDLT were enrolled to undergo 64-detector-row spiral CT and the imaging data at the hepatic venous phase was used for whole and partial liver volumetric measurement on a dedicated image postprocessing workstation. The resected part of donor liver was weighed during the operation. Statistical analysis with SPSS15.0 was used to analyze the correlation between the estimated liver volume by CT and the actual graft weight. RESULTS The graft volume calculated preoperatively by CT (293.35 ± 53.43 ml) was significantly larger than measured graft weight during the operation (252.82 ± 50.96 g) (P < 0.05). All corresponding pre- and intraoperative data correlated significantly (R = 0.885) (P < 0.001). Intraoperatively expected weight (W (intraop)) in grams and volume calculated preoperatively by CT (V (preop)) in milliliters can be calculated with the equation W (intraop) (g) = 0.844 × V (preop) (ml) + 5.271. CONCLUSION Liver volume calculated by 64-detector-row spiral CT preoperatively can predict the actual graft weight, which is very useful in donor selection in LDLT.

Abstract
BACKGROUND Ischaemic preconditioning (IPC) of the right liver graft in the donor has not been studied in adult-to-adult living related liver transplantation (LRLT). OBJECTIVE To assess the IPC effect of the graft on ischaemia reperfusion injury in the recipient and compare recipient and donor outcomes with and without preconditioned grafts. PATIENTS AND METHODS Alternate patients were transplanted with right lobe grafts that were (n = 22; Group (Precond)) or were not (n = 22; Group (Control)) subjected to IPC in the living donor. Liver ischaemia-reperfusion injury, liver/kidney function, morbidity/mortality rates and outcomes were compared. Univariate and multivariate analyses were performed to identify factors predictive of the aspartate aminotransferase (AST) peak and minimum prothrombin time. RESULTS Both groups had similar length of hospital stay, morbidity/mortality, primary non-function and acute rejection rates. Post-operative AST (P = 0.8) and alanine aminotransferase (ALT) peaks (P = 0.6) were similar in both groups (307 +/- 189 and 437 +/- 302 vs. 290 +/- 146 and 496 +/- 343, respectively). In univariate analysis, only pre-operative AST and warm ischemia time (WIT) were significantly associated with post-operative AST peak (in recipients). In multivariate analysis, the graft/recipient weight ratio (P = 0.003) and pre-operative bilirubin concentration (P = 0.004) were significantly predictive of minimum prothrombin time post-transplantation. CONCLUSIONS Graft IPC in the living related donor is not associated with any benefit for the recipient or the donor and its clinical value remains uncertain.

Abstract
BACKGROUND After right lobe donation, biliary complication is the main cause of morbidity. Mortality after right lobe donation has been estimated to be less than 0.5%. PATIENTS AND METHODS Between November 2001 and December 2008, 207 adult-to-adult living donor liver transplantations (ALDLT) were undertaken using right lobe grafts. Donors included 173 men and 34 women with a mean age of 28.4 +/- 5.2 years. RESULTS Siblings comprised 144 (69.6%) cases whereas unrelated donors comprised 63 (30.4%) with a mean body mass index (BMI) of 25.2 +/- 2.4. Single and multiple right hepatic ducts (RHD) were present in 82 (39.6%) and 125 (60.3%) donors, respectively. Mean operative time was 360 +/- 50 min with an estimated blood loss of 950 +/- 450 ml and returned cell-saver amount of 450 +/- 334 ml. Mean donor remnant liver volume was 33.5 +/- 3.2%. Mean intensive care unit (ICU) stay was 3 +/- 0.7 days and mean hospital stay was 14 +/- 3.5 days. Modified Clavien classifications were used to stratify all donor biliary complications The overall biliary complications occurred in 27 cases (13.0%). After modified Clavien classification, biliary complications were graded as grade I (n= 10), grade II (n= 2), grade III (n= 14) and grade V (n= 1). Grade I and II (n= 12) biliary complications were successfully managed conservatively. Grade III cases were treated using ultrasound-guided aspiration (USGA), endoscopic retrograde cholangiography (ERCP) and surgery in 10, 2 and 2 donors, respectively. Single donor mortality (Grade V) (0.4%) occurred after uncontrolled biliary leakage with peritonitis that necessitated exploration followed by ERCP with stent insertion but the donor died on day 43 as a result of ongoing sepsis. CONCLUSION Although the majority of biliary complications are minor and can be managed conservatively, uncontrolled biliary leakage is a serious morbidity that should be avoided as it could lead to mortality.

Abstract
AIMS To identify the normal range of liver stiffness (LS) values by recruiting healthy living liver and kidney donors in South Korea. METHODS Liver stiffness measurement (LSM) was performed in 69 healthy living liver and kidney donors who were admitted for transplantation. None of the subjects suffered from diabetes mellitus, hypertension, hepatitis B virus infection, hepatitis C virus infection, heart dysfunction, liver dysfunction or metabolic syndrome. RESULTS LSM failure rate was 2.7%. Among 12 liver donors (17.4%) with available liver histology, eight showed normal liver histology and four showed liver steatosis of <5% of the hepatocytes. The mean age of our study population was 38.9+/-11.9 years (35 men and 34 women), with a mean LS value of 4.6+/-0.5 kPa (range 3.3-5.6 kPa). LS values were not significantly different between men (4.6+/-0.6 kPa) and women (4.5+/-0.5 kPa, P=0.636), nor were they significantly different according to age (P=0.851). Using the fifth and 95th percentiles, we determined the normal range of LS values to be 3.9-5.3 kPa. CONCLUSIONS We identified the normal range of LS values and found that LS values were not significantly influenced by age and gender.

Abstract
BACKGROUND Intrahepatic anatomic variations have been associated with both morbidity and mortality associated with live donor liver transplantation. The aim of our study was to evaluate central hilar and peripheral segmental vascular/biliary anatomy in right graft living donor liver transplantation. METHODS From January 2003 to August 2007, three-dimensional (3D) computed tomography (CT) reconstructions and virtual 3D hepatectomies were performed in 71 consecutive right graft live liver donors. A combined two-level classification system addressing the four possible combinations of normal (N) and abnormal (A) central hilar and peripheral features based on both the existing classification and our own classification for portal (portal vein, PV), arterial (hepatic artery, HA) and biliary (bile duct, BD) systems was defined as follows: type I, N/N; type II, N/A; type III, A/N; and type IV, A/A. RESULTS A simultaneous normal central hilar and peripheral segmental (N/N) anatomy for each system (PV, HA, BD) was found in <50% of grafts. The highest incidence of complex vascular and biliary reconstructions was observed with grafts having abnormal central (type III) or combined abnormal central/peripheral (type IV) anatomy. Central hilar arterial and biliary anomalies were predictors of morbidity by both univariable and multivariable analyses. CONCLUSIONS Our two-level classification and 3D imaging techniques allowed a cautious surgical approach in high-risk cases. Central hilar anatomic variants of the arterial and biliary systems were associated with increased morbidity. Further randomized trials will help determine the precise extent of our observations.

Abstract
Abstract
Background
Postoperative venous congestion can lead to graft and remnant liver failure in living donor liver transplantation. This study was designed to delineate ‘territorial belonging’ of the middle hepatic vein (MHV) and to identify hepatic venous anatomy at high risk of outflow congestion.
Methods
MHV belonging patterns for right (RHL) and left (LHL) hemilivers were evaluated by three-dimensional computed tomographic reconstruction and virtual hepatectomy in 138 consecutive living liver donor candidates.
Results
The right hepatic vein (RHV) was dominant in 84·1 per cent and an accessory inferior hepatic vein (IHV) was present in 47·1 per cent of livers. Three MHV belonging types were identified for the RHL. Strong and complex MHV types A and C were associated with large RHL venous congestion. The MHV belonged to the LHL in 65·9 per cent, draining 37 per cent of this hemiliver. In virtual liver resections, left MHV type D was a risk category for small left liver remnants.
Conclusion
MHV territorial belonging types A and C were identified as high risk for RHL venous congestion. Their presence should prompt consideration of either inclusion of the MHV with the right graft or reconstruction of its tributaries, and preservation of IHV territory.

Abstract
AIM To estimate if and to what extent long acting octreotide (LAR) improves survival and quality of life in patients with advanced hepatocellular carcinoma (HCC). METHODS A total of 127 cirrhotics, stages A-B, due to chronic viral infections and with advanced HCC, were enrolled in the study. Scintigraphy with 111Indium labeled octreotide was performed in all cases. The patients with increased accumulation of radionuclear compound were randomized to receive either oral placebo only or octreotide/octreotide LAR only as follows: octreotide 0.5 mg s.c. every 8 h for 6 wk, at the end of wk 4-8 octreotide LAR 20 mg i.m. and at the end of wk 12 and every 4 wk octreotide LAR 30 mg i.m.. Follow-up was worked out monthly as well as the estimation of quality of life (QLQ-C30 questionnaire). Patients with negative somatostatin receptors (SSTR) detection were followed up in the same manner. RESULTS Scintigraphy demonstrated SSTR in 61 patients. Thirty were randomized to receive only placebo and 31 only octreotide. A significantly higher survival time was observed for the octreotide group (49+/-6 wk) as compared to the control group (28+/-1 wk) and to the SSTR negative group (28+/-2 wk), LR=20.39, df=2, P<0.01. The octreotide group presented 68.5% lower hazard ratio [95% CI (47.4%-81.2%)]. During the first year, a 22%, 39% and 43% decrease in the QLQ-C30 score was observed in each group, respectively. CONCLUSION The proposed therapeutic approach has shown to improve the survival and quality of life in SSTR positive patients with advanced HCC.

Abstract
AIM: To estimate if and to what extent long acting octreotide (LAR) improves survival and quality of life in patients with advanced hepatocellular carcinoma (HCC).
METHODS: A total of 127 cirrhotics, stages A-B, due to chronic viral infections and with advanced HCC, were enrolled in the study. Scintigraphy with 111Indium labeled octreotide was performed in all cases. The patients with increased accumulation of radionuclear compound were randomized to receive either oral placebo only or octreotide/octreotide LAR only as follows: octreotide 0.5mg s.c. every 8 h for 6 wk, at the end of wk 4-8 octreotide LAR 20 mg i.m. and at the end of wk 12 and every 4 wk octreotide LAR 30mg i.m.. Follow-up was worked out monthly as well as the estimation of quality of life (QLQ-C30 questionnaire). Patients with negative somatostatin receptors (SSTR) detection were followed up in the same manner.
RESULTS: Scintigraphy demonstrated SSTR in 61 patients. Thirty were randomized to receive only placebo and 31 only octreotide. A significantly higher survival time was observed for the octreotide group (49 ± 6 wk) as compared to the control group (28 ± 1 wk) and to the SSTR negative group (28 ± 2 wk), LR = 20.39, df = 2, P < 0.01. The octreotide group presented 68.5% lower hazard ratio [95% CI (47.4%-81.2%)]. During the first year, a 22%, 39% and 43% decrease in the QLQ-C30 score was observed in each group respectively.
CONCLUSION: The proposed therapeutic approach has shown to improve the survival and quality of life in SSTR positive patients with advanced HCC.

Abstract
The aim of this paper is to report the authors' experience in performing adult-to-adult living donor liver transplantation (LDLT) by using a modified technique in using grafts of the right lobe of the liver. From January 2002 to September 2006, 56 adult patients underwent LDLT using right lobe grafts at the West China Hospital, Sichuan University Medical School, China. All patients underwent a modified operation designed to improve the reconstruction of the right hepatic vein (RHV) and the tributariers of the middle hepatic vein (MHV) by interposing a vessel graft, and by anastomosing the hepatic arteries and bile ducts. There were no severe complications or deaths in all donors. Fifty-two (92.8%) recipients survived the operations. Among the 56 recipients, complications were seen in 15 recipients (26.8%), including hepatic vein stricture (one case), small-for-size syndrome (one case), hepatic artery thrombosis (two cases), intestinal bleeding (one case), bile leakage (two cases), left subphrenic abscess (one case), renal failure (two cases) and pulmonary infection (five cases). Within three months after transplantation, four recipients (7.14%) died due to small-for-size syndrome (one case), renal failure (one case) and multiple organ failure (two cases). All patients underwent direct anastomoses of the RHV and the inferior vena cava (IVC), and in 23 cases, reconstruction of the right inferior hepatic vein was also done. In 24 patients, the reconstruction of the tributaries of the MHV was also done by interposing a vessel graft to provide sufficient venous outflow. Trifurcation of the portal vein was seen in nine cases. Thus, veno-plasty or separate anastomoses were performed. The graft and recipient body weight ratios (GRWR) were between 0.72% and 1.43%, and in three cases it was <0.8%. The graft weight to recipient standard liver volume ratios (GV/SLV) were between 31.86% and 71.68%, among which four cases had <40%. No "small-for-size syndrome" occurred. With modification of the surgical technique, especially in the reconstruction of the hepatic vein to provide sufficient venous outflow, living donor liver grafts in adults using the right lobe of the liver can become a relatively safe procedure and prevent the "small-for-size syndrome".

Abstract
BACKGROUND Preoperative systemic chemotherapy is increasingly used in patients who undergo hepatic resection for colorectal liver metastases (CLM). Although chemotherapy-related hepatic injury has been reported, the incidence and the effect of such injury on patient outcome remain ill defined. METHODS A systematic review of relevant studies published before May 2006 was performed. Studies that reported on liver injury associated with preoperative chemotherapy for CLM were identified and data on chemotherapy-specific liver injury and patient outcome following hepatic resection were synthesized and tabulated. RESULTS Hepatic steatosis, a mild manifestation of non-alcoholic fatty liver disease (NAFLD), may occur after treatment with 5-fluorouracil and is associated with increased postoperative morbidity. Non-alcoholic steatohepatitis, a serious complication of NAFLD that includes inflammation and hepatocyte damage, can occur after treatment with irinotecan, especially in obese patients. Irinotecan-associated steatohepatitis can affect hepatic reserve and increase morbidity and mortality after hepatectomy. Hepatic sinusoidal obstruction syndrome can occur in patients treated with oxaliplatin, but does not appear to be associated with an increased risk of perioperative death. CONCLUSION Preoperative chemotherapy for CLM induces regimen-specific hepatic changes that can affect patient outcome. Both response rate and toxicity should be considered when selecting preoperative chemotherapy in patients with CLM.

Abstract
An adequate venous outflow is essential for securing viability of both graft and remnant in adult living donor liver transplantation (ALDLT). Seventy-five potential live liver donors were evaluated for LDLT by means of an "all-in-one" CT, which defined the biliary tree, portal vein, hepatic artery, and hepatic vein anatomy. The acquired data sets were further analysed by means of the software HepaVision (MeVis, Germany). Only a minority (29%) of potential donors were found to have a vascular and biliary anatomy consistent with the classically described "normal" patterns. The vast majority (71%) had "anatomical variations". Thirty-nine (52%) donors underwent ALDLT hepatectomy. The right hepatic vein was dominant in 64 cases, representing 48 +/- 6% of the total liver volume (TLV). The middle hepatic vein was dominant in 11 cases, making up 40 +/- 8% of the TLV. The left hepatic vein was never dominant. The volume contribution of the middle hepatic vein (MHV) was 114-782 ml for the right and 87-419 ml for the left hemiliver. Computer-assisted planning allows for the 3D reconstruction of the vascular and biliary anatomy, automatic calculation of the total and territorial liver volumes, and risk analysis of hepatic vein dominance relationships. This comprehensive data acquisition supports preoperative evaluation and provides a high degree of safety for donors and improved outcomes for recipients.

Abstract
AIM: To compare the value of endoscopic retrograde cholangiography (ERC) and standard T2-weighted magnetic resonance cholangiography (MRC) in the evaluation process as adult-to-adult right lobe living donor liver transplantation (LDLTx) demands a successful outcome, and exact knowledge of the biliary tree is implicated to avoid biliary complications, postoperatively.
METHODS: After starting the LDLTx program, 18 liver transplant candidates were selected for LDLTx by a stepwise evaluation process. ERC and standard T2-weighted MRC were performed to evaluate the biliary system of the donor liver. The anatomical findings of ERC and MRC mapping were compared using the Ohkubo classification.
RESULTS: ERC allowed mapping of the whole biliary system in 15/15 (100%) cases, including 14/15 (93.3%) with biliary variants while routine MRC was only accurate in 2/13 (15.4%) cases. MRC was limited in depicting the biliary system proximal of the hepatic bifurcation. Postoperative biliary complications occurred in 2 donors and 8 recipients. Biliary complications were associated with Ohkubo type C, E or G in 6/8 recipients, and 2/3 recipients with biliary leak received a graft with multiple (≥2) bile ducts.
CONCLUSION: Pretransplant ERC is safe and superior over standard MRC for detection of biliary variations that occur with a high frequency. However, precise knowledge of biliary variants did not reduce the incidence of postoperative biliary complications.

Abstract
PURPOSE To assess the feasibility of percutaneous transhepatic biliary drainage (PTBD) for the treatment of postsurgical biliary leaks in patients with nondilated intrahepatic bile ducts, its efficacy in restoring the integrity of bile ducts, and technical procedures to reduce morbidity. METHODS Seventeen patients out of 936 undergoing PTBD over a 20-year period had a noncholestatic liver and were retrospectively reviewed. All patients underwent surgery for cancer and suffered a postsurgical biliary leak of 345 ml/day on average; 71% were in poor condition and required permanent nutritional support. An endoscopic approach failed or was excluded due to inaccessibility of the bile ducts. RESULTS Established biliary leaks and site of origin were diagnosed an average of 21 days (range 1-90 days) after surgery. In all cases percutaneous access to the biliary tree was achieved. An external (preleakage) drain was applied in 7 cases, 9 patients had an external-internal fistula bridging catheter, and 1 patient had a percutaneous hepatogastrostomy. Fistulas healed in an average of 31 days (range 3-118 days ) in 15 of 17 patients (88%) following PTBD. No major complications occurred after drainage. Post-PTBD cholangitis was observed in 6 of 17 patients (35%) and was related to biliary sludge formation occurring mostly when drainage lasted >30 days and was of the external-internal type. Median patient survival was 17.7 months and in all cases the repaired biliary leaks remained healed. CONCLUSIONS PTBD is a feasible, effective, and safe procedure for the treatment of postsurgical biliary leaks. It is therefore a reliable alternative to surgical repair, which entails longer hospitalization and higher costs.

Abstract
OBJECTIVE The objective of this study was to characterize the patient population with respect to patient selection, assess surgical morbidity and graft failures, and analyze the contribution of perioperative clinical factors to recipient outcome in adult living donor liver transplantation (ALDLT). SUMMARY BACKGROUND DATA Previous reports have been center-specific or from large databases lacking detailed variables. The Adult-to-Adult Living Donor Liver Transplantation Cohort Study (A2ALL) represents the first detailed North American multicenter report of recipient risk and outcome aiming to characterize variables predictive of graft failure. METHODS Three hundred eighty-five ALDLT recipients transplanted at 9 centers were studied with analysis of over 35 donor, recipient, intraoperative, and postoperative variables. Cox regression models were used to examine the relationship of variables to the risk of graft failure. RESULTS Ninety-day and 1-year graft survival were 87% and 81%, respectively. Fifty-one (13.2%) grafts failed in the first 90 days. The most common causes of graft failure were vascular thrombosis, primary nonfunction, and sepsis. Biliary complications were common (30% early, 11% late). Older recipient age and length of cold ischemia were significant predictors of graft failure. Center experience greater than 20 ALDLT was associated with a significantly lower risk of graft failure. Recipient Model for End-stage Liver Disease score and graft size were not significant predictors. CONCLUSIONS This multicenter A2ALL experience provides evidence that ALDLT is a viable option for liver replacement. Older recipient age and prolonged cold ischemia time increase the risk of graft failure. Outcomes improve with increasing center experience.

Abstract
There are no data regarding hepatic lobe donation effects on donor life insurability. Two investigators called 10 agents of 10 different large life insurance companies. One investigator gave a fictitious profile: Caucasian man, 33 years old, nonsmoker, without medical problems (control profile [CP]). The other investigator used the same profile with a history of uncomplicated right lobe donation 12 months earlier (donor profile [DP]). Investigators asked for premium quotes on a $100,000 term life policy. No medical testing or record review was allowed. Investigators were blinded to the results of each other's calls. Agents were unaware of the study. We documented underwriting decisions, premiums quoted, stipulations, number of phone calls, and phone time. All 10 companies would pursue underwriting CP at their lowest, "preferred" rate. Five would do the same for DP. Two might underwrite DP at a more expensive "standard" rate, but a "preferred" rate would be less likely. One would underwrite DP at the "standard" rate; one would not underwrite DP. One agent did not return follow-up calls (DP insurability < CP, P = 0.04). Mean quoted premiums were lower for CP vs. DP ($189/yr. vs. $202/yr., P = 0.56). Median number of phone calls required was 1 for CP and 3 for DP (P = 0.01). Mean telephone minutes were 4.2 for CP and 8.0 for DP (P = 0.004). In conclusion, right hepatic lobe donation decreases life insurability 1 year after uncomplicated donation. Donors can expect some increased difficulty obtaining life insurance, but they should find a company willing to pursue underwriting. The premium paid may be slightly higher.

Abstract
The first successful living donor liver transplantation (LDLT) was performed in a child in 1989 in Brisbane and in an adult in 1994 by the Shinshu group. Over the past few years, LDLT has increased worldwide and is now an established alternative to deceased donor liver transplantation. The surgical procedures for LDLT are more technically challenging than those for whole liver transplantation. LDLT requires a full understanding of the hepatobiliary anatomy and continuous technical refinement of the procedure. Some of the technical highlights include selective vascular occlusion techniques for donor hepatectomy, hepatic arterial reconstruction under the microscope and the introduction of intraoperative ultrasound, graft volume estimation and hepatic venous reconstruction, all of which have improved the success rate of LDLT over the past few years. This review focuses on recent trends and surgical techniques for LDLT.

Abstract
OBJECTIVE Developing strategies for transfusion-free live donor liver transplantation in Jehovah's Witness patients. SUMMARY BACKGROUND DATA Liver transplantation is the standard of care for patients with end-stage liver disease. A disproportionate increase in transplant candidates and an allocation policy restructuring, favoring patients with advanced disease, have led to longer waiting time and increased medical acuity for transplant recipients. Consequently, Jehovah's Witness patients, who refuse blood product transfusion, are usually excluded from liver transplantation. We combined blood augmentation and conservation practices with live donor liver transplantation (LDLT) to accomplish successful LDLT in Jehovah's Witness patients without blood products. Our algorithm provides broad possibilities for blood conservation for all surgical patients. METHODS From September 1998 until June 2001, 38 LDLTs were performed at Keck USC School of Medicine: 8 in Jehovah's Witness patients (transfusion-free group) and 30 in non-Jehovah's Witness patients (transfusion-eligible group). All transfusion-free patients underwent preoperative blood augmentation with erythropoietin, intraoperative cell salvage, and acute normovolemic hemodilution. These techniques were used in only 7%, 80%, and 10%, respectively, in transfusion-eligible patients. Perioperative clinical data and outcomes were retrospectively reviewed. Data from both groups were statistically analyzed. RESULTS Preoperative liver disease severity was similar in both groups; however, transfusion-free patients had significantly higher hematocrit levels following erythropoietin augmentation. Operative time, blood loss, and postoperative hematocrits were similar in both groups. No blood products were used in transfusion-free patients while 80% of transfusion-eligible patients received a median of 4.5+/- 3.5 units of packed red cell. ICU and total hospital stay were similar in both groups. The survival rate was 100% in transfusion-free patients and 90% in transfusion-eligible patients. CONCLUSIONS Timely LDLT can be done successfully without blood product transfusion in selected patients. Preoperative preparation, intraoperative cell salvage, and acute normovolemic hemodilution are essential. These techniques may be widely applied to all patients for several surgical procedures. Chronic blood product shortages, as well as the known and unknown risk of blood products, should serve as the driving force for development of transfusion-free technology.

Abstract
BACKGROUND There has been concern that adult living-donor liver transplantation (LLTx) for hepatitis C virus (HCV) infection may lead to recurrent disease that is more severe compared with the results of cadaveric LTx (CLTx), because the smaller sized graft in LLTx regenerates and may increase viral replication. This study examines the survival outcome and HCV recurrence in CLTx versus LLTx performed at a single institution. METHOD A total of 100 consecutive adult recipients (75 men and 25 women; mean age 49.9+/-8.4 years) of LTx (65 CLTxs and 35 LLTxs performed July 2000-July 2002) who tested positive for HCV by polymerase chain reaction were examined retrospectively until October 2003. All patients received tacrolimus-based immunosuppression with mycophenolate mofetil and steroids. RESULTS The overall actual patient survival was 85% (83.1% for CLTx vs. 88.6% for LLTx). The 39-month Kaplan-Meier actuarial patient survivals were 75.1% for CLTx and 88.6% for LLTx. Of 15 deaths, 6 were the result of recurrent HCV (five CLTxs and one LLTx), and of 10 retransplants, 2 were related to recurrent HCV (one CLTx and one LLTx). The rates of recurrence were 72.3% and 77.1%, the hepatitis activity indices were 5.4 + 2.4 and 6.2 + 2.8, the fibrosis scores were 1.4+/-1.4 and 1.5+/-1.3, and the times to recurrence were 318+/-269 days and 394+/-250 days for CLTx and LLTx, respectively. None of the differences between the two groups were significant. CONCLUSION No detrimental effect of HCV infection was found in LLTx recipients when compared with contemporaneous CLTx recipients. Patient survival, graft survival, rate of HCV recurrence, severity of HCV recurrence, graft loss from HCV, and interval for recurrence in CLTx and LLTx were similar.

Abstract
Venous congestion of segments V and VIII is observed frequently in living-donor right lobe liver transplants without middle hepatic vein (MHV) drainage, and can be a cause of graft dysfunction and failure. Inclusion of the MHV with the graft is controversial, however, because of the perceived potential for increased donor morbidity. We compared the outcome of living liver donors in whom the MHV was either left intact in the donor (group 1; n = 28) or was removed with the graft (group 2; n = 28). All prospective donors completed an extensive multidisciplinary evaluation to determine suitability for surgery and to ensure that the MHV could be removed safely without compromising venous outflow from the remaining liver. Patient demographics including age, weight, body-mass index, and liver volumetry as determined by computerized tomography were similar in both groups. Operative time in group 2 was significantly shorter than in group 1. There was no difference in estimated blood loss, transfusion requirements, peak serum liver tests, time interval from surgery to complete normalization of liver tests, complications, and length of hospitalization. We conclude that including the MHV with living-donor right lobe grafts can be performed safely in most donors.

Abstract
OBJECTIVE To present an institutional experience with the use of right liver grafts in adult patients and to assess the practicability and efficacy of this procedure by analyzing the results. SUMMARY BACKGROUND DATA Living donor liver transplantation (LDLT) for the pediatric population has gained worldwide acceptance. In the past few years, LDLT has also become feasible for adult patients due to technical evolution in hepatobiliary surgery and increased experience with reduced-size and split-liver transplants. Nevertheless, some graft losses remain unexplained and are possibly due to unrecognized venous outflow problems. METHODS From April 1998 to September 2002, we performed 74 right LDLTs (segments 5-8). The 74 donors were selected from 474 candidates according to standard protocol. The median age of the donors was 35 years (range 18-58 years) and 51 years (range 18-64 years) in recipients. Standard and extended indications for transplantation were considered. Over the period reported, technical modifications in the bile duct anastomosis (duct-to-duct, end-to-end, or end-to-side) and a new graft implantation technique that provides maximized venous outflow, leading to outcome improvement, were developed. RESULTS 64.9% of patients had liver cirrhosis and 35.1% had malignancy. While 44 donors (59.5%) presented an uneventful postoperative course, 27% minor (pleural effusion, pneumonia, venous thrombosis, wound infection, incisional hernia) and 13.5% major (biliary leakage, death of a donor due to unrecognized hereditary liver disease, and consecutive liver insufficiency) complications were documented. In recipients, 23% biliary complications and 6.8% hepatic artery thrombosis occurred. The overall patient and graft survival rate after 1 year was 79.4% and 75.3%, respectively. In cases with extended indication, the patient survival rate was 74% and the graft survival rate 68% at 12 months. Using technical modifications in the last 10 recipients, including 2 critically decompensated cirrhotics, the survival rate was 100% at a median follow-up of 3.5 months. CONCLUSIONS In our transplant program, living donor liver transplantation has become a standard option in the adult patient population. The critical issue of this procedure is donor morbidity. Technical improvements in the harvesting and implantation of right grafts can also offer hope to patients with challenging forms of end-stage liver disease or malignant liver tumors.
