Abstract
Non-alcoholic fatty liver disease (NAFLD) is estimated to affect 24% of the global adult population. NAFLD is a major risk factor for the development of cirrhosis and hepatocellular carcinoma, as well as being strongly associated with type 2 diabetes and cardiovascular disease. It has been proposed that up to 88% of obese adults have NAFLD, and with global obesity rates increasing, this disease is set to become even more prevalent. Despite intense research in this field, the molecular processes underlying the pathology of NAFLD remain poorly understood. Hepatic intracellular lipid accumulation may lead to dysregulated tricarboxylic acid (TCA) cycle activity and associated alterations in metabolite levels. The TCA cycle metabolites alpha-ketoglutarate, succinate and fumarate are allosteric regulators of the alpha-ketoglutarate-dependent dioxygenase family of enzymes. The enzymes within this family have multiple targets, including DNA and chromatin, and thus may be capable of modulating gene transcription in response to intracellular lipid accumulation through alteration of the epigenome. In this review, we discuss what is currently understood in the field and suggest areas for future research which may lead to the development of novel preventative or therapeutic interventions for NAFLD.

Abstract
Live donor adult liver transplantation (LDALT) utilizing right-lobe grafts is now acceptable as an alternative to cadaveric orthotopic liver transplantation (OLT). However, some LDALTs fail and require urgent OLT or result in recipient death. Our aim was to determine the basis of LDALT failure. Liver specimens from 49 LDALT recipients were evaluated and the findings correlated with clinical outcome. Ten patients (20.4%) had either early (< 1 month) or late (> 1 month) graft failure. Eight early failures, 7 of which occurred among our first 25 cases, were due to extensive liver parenchymal necrosis as a result of hepatic artery thrombosis (n=3), portal vein thrombosis (n= 1), hyperperfusion syndrome (n= 1), complete graft thrombosis (n= 1) with Factor V Leiden on a regimen of therapeutic heparin (n=1), sepsis and concomitant graft dysfunction with venous outflow tract injury (n=I), and venous outflow tract thrombosis and parenchymal thermal injury with sepsis (n=1). Preoperative, intraoperative, or postoperative severe vessel wall injury was evident in 6/8 early failures. TWo patients had late graft failure, 1 from recurrent hepatitis C and 1 with sepsis/multisystem organ failure. There were no significant differences in graft size, rejection episodes, or operative or ischemic times between patients with and without graft failure. In conclusion, LDALT failed in 10/49 (20%) of our patients, with 8/10 occurring within 1 month post-LDALT owing to vascular/thrombotic complications experienced during the early phase of our institutional experience. Perioperative vessel wall injury appeared to be a major factor in predicting early graft loss.

Abstract
The lack of use of a common grading system in reporting morbidity impedes estimation of the true risk to a right lobe living donor (RLLD). We report outcomes in 91 consecutive RLLD's using the validated 5-tier Clavien grading and a quality of life (QOL) questionnaire. The median follow-up was 79 months. The donors were predominantly female (66%), 22 (24%) received autologous blood transfusions. Fifty-three complications occurred in 43 donors (47% morbidity), 19 (37%) were ≥ Grade III, biliary fistula (14%) was the most common. There was no donor mortality. Two intraoperative complications could not be graded and two disfiguring complications in female donors were graded as minor. Two subgroups (first 46 vs. later 45 donors) were compared to study the presence if any, of a learning curve. The later 45 donors had lesser autologous transfusions, lesser rehospitalization and no reoperation and a reduction in the proportion of ≥ Grade III (major) complications (24% vs. 50%; p = 0.06). In the long term, donors expressed an overall sense of well being, but some sequelae of surgery do restrain their current lifestyle. Our results warn against lackadaisical vigilance once RLLD hepatectomy becomes routine.

Abstract
A 35-year-old mother was scheduled to be the living donor for liver transplantation to her second son, who suffered from biliary atresia complicated with biliary cirrhosis at the age of 2 years. The operative plan was to recover the left lateral segment of the mother’s liver for living donor transplantation. With the use of cholangiography at the time of surgery, we found the right anterior segmental duct (RASD) emptying directly into the cystic duct, and the catheter passed into the RASD. After repairing the incision in the cystic duct, transplantation was successfully performed. Her postoperative course was uneventful. Biliary anatomical variations were frequently encountered, however, this variation has very rarely been reported. If the RASD was divided, the repair would be very difficult because the duct will not dilate sufficiently in an otherwise healthy donor. Meticulous preoperative evaluation of the living donor’s biliary anatomy, especially using magnetic resonance cholangiography and careful intraoperative techniques, is important to prevent bile duct injury and avoid the risk to the healthy donor.

Abstract
With the advances in technical skills, management of postoperative complications and improvements in immunosuppressive drugs, liver transplantation is the standard treatment for many patients with chronic liver disease. Today, shortage of donor organs seems to be the major limiting factor for the application of liver transplantation. This review focuses on five issues that are challenging to clinical practice of liver transplantation and relevant to gastroenterologists. These include living donor liver transplantation, recurrent viral hepatitis, non-heart-beating donors, hepatocellular carcinoma, and ABO incompatible liver transplantation. Living donor and non-heart beating donor transplantations were initiated as a solution to increase the donor organ pool and it is expected that there will be an increase in the number of these donors. Recurrent hepatitis C and hepatocellular carcinoma following liver transplantation are among major problems and ongoing research in these diseases may lead to better outcomes in these recipients.

Abstract
BACKGROUND In living donor liver transplantation (LDLT), the liver donor is almost always a blood relative; therefore, the donor is sometimes a heterozygous carrier of inheritable diseases. The use of such carriers as donors has not been validated. The aim of the present study was to evaluate the outcome of LDLT for noncirrhotic inheritable metabolic liver disease (NCIMLD) to clarify the effects of using a heterozygous carrier as a donor. METHODS Between June 1990 and December 2003, 21 patients with NCIMLD underwent LDLT at our institution. The indications for LDLT included type II citrullinemia (n = 7), ornithine transcarbamylase deficiency (n = 6), propionic acidemia (n = 3), Crigler-Najjar syndrome type I (n = 2), methylmalonic acidemia (n = 2), and familial amyloid polyneuropathy (n = 1). Of these 21 recipients, six underwent auxiliary partial orthotopic liver transplantation. RESULTS The cumulative survival rate of the recipients was 85.7% at both 1 and 5 years after operation. All surviving recipients are currently doing well without sequelae of the original diseases, including neurological impairments or physical growth retardation. Twelve of the 21 donors were considered to be heterozygous carriers based on the modes of inheritance of the recipients' diseases and preoperative donor medical examinations. All donors were uneventfully discharged from the hospital and have been doing well since discharge. No mortality or morbidity related to the use of heterozygous donors was observed in donors or recipients. CONCLUSIONS Our results suggest that the use of heterozygous donors in LDLT for NCIMLD has no negative impact on either donors or recipients, although some issues remain unsolved and should be evaluated in further studies.

Abstract
OBJECTIVE During the last 14 years, living donor liver transplantation (LDLT) has evolved to an indispensable surgical strategy to minimize mortality of adult and pediatric patients awaiting transplantation. The crucial prerequisite to performing this procedure is a minimal morbidity and mortality risk to the healthy living donor. Little is known about the learning curve involved with this type of surgery. PATIENTS AND METHODS From January 1991 to August 2003, a total of 165 LDLTs were performed in our center. Of these, 135 were donations of the left-lateral lobe (LL, segments II and III), 3 were of the left lobe (L, segments II-IV), 3 were full-left lobes (FL, segments I-IV), and 24 were of the full-right lobe (FR, segments V-VIII). We divided the procedures into 3 periods: period 1 included the years 1991 to 1995 (LL, n = 49; L, n = 2; FR, n = 1), period 2 covered 1996 to 2000 (LL, n = 47), and period 3 covered 2001 to August 2003 (LL, n = 39; FR, n = 23; FL, n = 3; L, n = 1). Perioperative mortality and morbidity were assessed using a standardized classification. Length of stay in intensive care unit, postoperative hospital stay, laboratory results (bilirubin, INR, and LFTs), morbidity, and the different types of grafts in the 3 different periods were compared. RESULTS One early donor death was observed in period 1 (03/07/93, case 30; total mortality, 0.61.%). Since 1991, the perioperative morbidity has continually declined (53.8% vs. 23.4% vs. 9.2%). In period 1, 28 patients had 40 complications. In period 2, 11 patients had 12 complications, and in period 3, 6 patients had 9 complications. Within the first period, 1 donor underwent relaparotomy because of bile leakage. Postoperative hospital stay was 10 days, 7 days, and 6 days, respectively. Donation of the full right lobe, in comparison with that of the left lateral lobe, resulted in a significantly diminished liver function (bilirubin and INR) during the first 5 days after donation but did not increase morbidity. One donor from period 1 experienced late death caused by amyotrophic lateral sclerosis. CONCLUSIONS In a single center, morbidity after living liver donation strongly correlates to center experience. Despite the additional risks associated with temporary reduction of liver function, this experience enabled the team to bypass part of the learning curve when starting right lobe donation. Specific training of the surgical team and coaching by an experienced center should be implemented for centers offering this procedure to avoid the learning curve.

Abstract
Multi-detector row computed tomography was performed for the preharvest evaluation of 14 potential living liver donors. Both a biliary contrast agent and a conventional iodinated contrast agent were administered intravenously. This protocol included acquisition of three subsequent scans and allowed accurate assessment of the hepatic parenchymal morphology and volumetrics and a detailed analysis of the biliary and vascular anatomies.

Abstract
BACKGROUND In the past, follow-up surveys for living-related liver transplantation (LRLT) mainly focused on the medical outcome of recipients and donors. In this survey the prevalence of personal, familial, or economic problems of the donors and changes of quality of life after donation were studied. METHODS Questionnaires were sent to 24 donors after right hepatectomy for LRLT (response 92%). The modified EUROTOLD (European Multicenter Study of Transplantation Using Living Donors) questionnaire was used to inquire about the decision-making process, family problems, and economic problems related to the donation. Global quality of life was measured with the SF-36 Health Survey. RESULTS For most donors the decision to donate was easy or not very difficult (21/22) and was made spontaneously (17/22). The amount of information about the risks of LRLT was limited at the time of decision but increased remarkably immediately before the operation. In 28%, family conflicts occurred (5/22). Retrospectively, all but two donors (91%) would donate again. On average, donors started working after 9 (+/-3.7) weeks and felt fully recovered after 13 (+/-7.3) weeks. Adverse financial affects were experienced by 41% of the donors (9/22) because of the donation, and four of those received a compensation. Importantly, quality of life did not differ between donors and nondonors. CONCLUSION Donors viewed LRLT positively. Quality of life after donation did not change. However, donors had a prolonged period of physical rehabilitation, and 41% experienced financial disadvantages.

Abstract
OBJECTIVE To analyse the outcome of six children with Crigler-Najjar syndrome type I (CNS-I) and report the first three living-related liver transplants for this syndrome in Saudi Arabia and the Middle East. SETTINGS To review the medical records of six children suffering from CNS-I, three of whom underwent living-related liver transplantation (LRLT) between 22 November 1998 and January 2001. MAIN RESULTS Living-related liver transplantation was performed in three children with a pre-transplant unconjugated bilirubin level of 362, 381 and 502 micromol/L, respectively, despite daily phototherapy of >or= 12 h. Two of the transplanted children developed acute hepatocellular rejection, which was successfully treated with methylprednisolone pulse therapy. One tested cytomegalovirus positive (using the PP65 method), but showed no signs of clinical infection and was treated with ganciclovir. One patient had a biliary leak at the cut surface of the graft which was surgically repaired. Post-operative bilirubin levels returned to normal in all three transplanted children and no further phototherapy was required. One patient, who was not transplanted but received phototherapy, developed severe neurological damage prior to the start of our living-related liver transplant programme with a bilirubin level of 450 micromol/L, her sister is still awaiting transplantation. A 14-yr-old child with a bilirubin level of 420 micromol/L is presently undergoing phototherapy whilst awaiting orthotopic liver transplantation because of the lack of a suitable living-related donor. Six siblings of the six children in our series were reported dead by the families. CONCLUSION Crigler-Najjar syndrome type I is a relatively common disease in Saudi Arabia for which LRLT is a curative treatment when performed at an early age before the development of kernicterus and neurological deficiency. In countries where there is a severe shortage of cadaveric organs, as is the case in Saudi Arabia, LRLT is the optimum treatment modality for this syndrome.

Abstract
In the Essen University Clinic for Psychotherapy and Psychosomatics, between January and December 2000, 54 potential liver donors and 12 kidney donors were examined. All the kidney donors were found to be suitable; 7 potential liver donors were rejected on psychosomatic grounds. Reasons for the rejection were addiction (1 donor), suspected financial dependency of the donor on the recipient (1 donor) and, in the case of one donor not related to the recipient, the apparent lack of a special emotional attachment. During the actual evaluation interview, 4 potential donors reversed their original decision. Such a psychosomatic evaluation is a great help for donors in clarifying their motives and their decision.

Abstract
The purpose of this study was to determine the practicability and diagnostic accuracy of a magnetic resonance (MR) protocol capable of replacing computed tomography, catheter angiography, and endoscopic retrograde cholangiopancreatography for the presurgical evaluation of potential liver donors before right hepatectomy. MR imaging (MRI) was performed on a 1.5 T scanner using a phased-array torso surface coil for signal reception. The following image sets were collected: axial two-dimensional (2D) T1-weighted fast low angle shot (FLASH), axial 2D T2-weighted half-Fourier acquisition single-shot turbo-spin-echo (HASTE) with fat saturation, coronal MR cholangio-pancreatography (MRCP) based on 2D multisection HASTE and single-section single-shot rapid acquisition with relaxation enhancement (RARE) imaging, dynamic contrast-enhanced three-dimensional (3D) FLASH, and contrast-enhanced T1-weighted FLASH. 3D FLASH data sets were collected before and after an intravenous administration of Multihance (gadobenate dimeglumine, Gd-BOPTA; Bracco, Milano, Italy), 0.2 mmol/kg of body weight. Thirty-eight potential liver donors were assessed by means of MRI. Twenty patients also underwent digital subtraction angiography (DSA). Of these, 16 patients underwent liver harvesting. MR angiography (MRA) data sets correlated with DSA results, and MRCP results correlated with intraoperative findings. Patients were excluded as potential donors based on insufficient liver mass of the left hepatic lobe (n = 5) or presence of hepatic pathological states (n = 9) seen at MRI, such as hemangiomas, focal nodular hyperplasias, or hepatic steatosis. MRCP showed the biliary system to the level of the first hepatic side branch. Dilated ducts were present in 4 patients. MRA depiction of hepatic arterial morphological characteristics correlated with catheter angiography results in all 20 patients: Three left hepatic arteries originating from the left gastric artery, three aberrant right hepatic arteries originating from the superior mesenteric artery, and two aberrant origins of both hepatic arteries and one common hepatic artery originating from the superior mesenteric artery were correctly identified on MRA. Similarly, the portal venous system was fully assessed on MRA. A comprehensive assessment of the hepatic parenchyma, biliary and pancreatic ductal system, and hepatic arterial, portal, and venous systems can be accomplished using the outlined protocol.

Abstract
Despite the increasing use of living donor liver transplantation, little is known about donor needs, concerns, and experiences. The goal of this study is to assess morbidity associated with living donation from a donor perspective, functional status after donation, and overall satisfaction with the donation process. We surveyed all living donors (LDs) from our center. Demographics, perioperative experience, and satisfaction with donation were assessed. The Medical Outcomes Study 12-Item Short-Form Survey (SF-12), a well-validated tool, measured overall health-related quality of life. Of 27 subjects eligible for the study, 27 subjects (100%) participated. Forty percent reported an event they deemed an immediate complication, of which 60% were recorded in the medical record. Complications requiring readmission were reported by 22%. Mean recovery time was 12 weeks (range, 1 to 52 weeks). No significant change was reported in physical activity, social activity, or emotional stability, and 92% of donors resumed their predonation occupation. Regardless of recipient outcome, 100% of donors would donate again and recommend donation to someone in contemplation. All surveyed LDs at our institution are satisfied with their donation decision. Morbidity in the first year after donation may be greater than previously appreciated. Despite complications, postoperative functional status of donors is equal to or better than population norms.

Abstract
With the success of pediatric live donor liver transplantation (LDLT) and the continued shortage of cadaveric donors, adult-to-adult LDLT has been performed at some centers, including ours. We performed a detailed histologic review of all liver specimens obtained from 9 adult recipients at and after LDLT and correlated these findings with the patients' course and outcome. Five patients had histologic evidence of biliary tract pathology; 3 of 5 required surgical or radiologic intervention. The other 2 had clinically insignificant biliary disease. Diffuse hepatocytic hemorrhagic necrosis secondary to massive portal blood flow after portal venous revascularization resulted in graft failure and retransplantation in a single patient with severe preoperative portal hypertension. Two perioperative deaths were caused by sepsis and multiorgan failure (day 25) and generalized thrombosis related to factor V Leiden (day 6). The preoperative diagnosis, presence of portal vein thrombosis in the native liver, postoperative cholangiopathy, and subcapsular hemorrhagic necrosis in donor liver wedge biopsies did not affect the short-term outcome. In conclusion, biliary tract pathology is common after adult-to-adult LDLT but does not negatively affect graft or patient survival. Infrequent but catastrophic vascular complications related to portal hemodynamics or thrombosis can result in graft loss and/or patient death.

Abstract
Living donor liver transplantation was developed in response to a shortage of full-size grafts for children. The progression from reduced-size cadaveric grafts to use of living donors occurred subsequent to expansion of liver anatomy knowledge and practical use of hepatic segments. A major benefit of pediatric live donor liver transplantation is the grafting of children without using livers from the cadaver donor pool. A major drawback of the procedure relates to the need to perform surgery and assign risk to an otherwise healthy individual. The ethical challenge has been discussed in detail and, although not ideal, the procedure "passes muster" on grounds of informed consent and the good of helping another human being. Formidable success appears to have been attained with the adult-to-adult procedure thus far; however, the transplant community still awaits center-specific and compiled data to determine whether the procedure truly reduces adult waiting list times for liver transplant recipients with minimal donor risk.

Abstract
Liver transplantation is now accepted as effective therapy in the treatment of acute and chronic hepatic failure. Improvements in surgical techniques and immune suppression have led to 5-year survival rates that exceed 70% in most centers. The success of transplantation has led to a dramatic increase in the number of candidates to over 14,000 places on the national waiting list. While the number of patients in need of transplantation increases, there has been little growth in the supply of available cadaveric organs, resulting in an organ shortage crisis. With waiting times often exceeding 1 to 2 years, the waiting list mortality now exceeds 10% in most regions. Several novel approaches have been developed to address the growing disparity between the limited supply and excessive demand for suitable organs.

Abstract
Survival after liver transplantation has steadily improved, in part because of newer immunosuppression, which may offer decreased long-term side effects. Reduction of steroids early in the course of transplant continues to be a goal, with satisfactory results in terms of both risk of rejection and reduction of side effects. Dominating the literature and the press in 1999 was the controversy surrounding the way in which livers are allocated. Regulation by the federal government was proposed to change the way the United Network of Organ Sharing distributes and allocates livers. Prompted by the shortage of organs, living-donor liver transplantation has blossomed. Continued experience in pediatric patients has shown excellent survival rate and quality of life. In adults, further experience is being gained with respect to the use of right lobes for transplantation. Early data suggest that this is a potential alternative to cadaveric transplantation in adults, with acceptable risk to the donor. Despite advances made in improving the technical aspects of transplantation, recurrent disease remains a significant issue. Lamivudine appears to be a potent inhibitor of hepatitis B virus DNA replication after liver transplantation, although resistance remains a significant problem. Further review of transplantation for hepatitis C virus is encouraging, with excellent five-year survival rate. However, studies evaluating the evolution of fibrosis in these patients throw caution on those results, showing increased progression to cirrhosis over time. Further follow-up of these patients is needed to more accurately assess long-term impact of hepatitis C on morbidity and mortality rates after liver transplantation.
