RESUMEN

Conventional selection criteria for liver transplantation (LT) in patients with hepatocellular carcinoma (HCC) are based on tumour size/number only, and do not consider vital surrogates of tumor biology such as alpha-fetoprotein (AFP) and tumor [18 F]fluorodeoxyglucose positron emission tomography ([18 F]FDG PET) avidity. We analyzed survival outcomes, and predictors of HCC recurrence in 405 patients with cirrhosis and HCC (HCC-cirr) who underwent living donor LT (LDLT) using our expanded selection criteria: no extrahepatic disease or major vascular invasion, irrespective of tumor size/number. Fifty-one percent patients had tumours beyond Milan, and 43% beyond the University of California San Francisco [UCSF] criteria. The 5-year overall survival (OS) and recurrence-free survival (RFS) were 64% and 70%, respectively. Three preoperatively available factors predicted recurrence: pre-LT AFP ≥100 ng/mL (P = 0.005; hazard ratio [HR], 2.190), tumor burden beyond the UCSF criteria (P = 0.001; HR, 2.640), and [18 F]FDG PET avidity (P = 0.004; HR, 2.442). A prognostic model based on the number and combination of the aforementioned preoperative risk factors was developed using a competing-risk RFS model. Three risk groups were identified: low (none or a single risk factor present, 9.3% recurrence), moderate (AFP ≥100 ng/mL and [18 F]FDG PET avidity, or beyond UCSF tumor and [18 F]FDG PET avidity, 25% recurrence), and high (AFP ≥100 ng/mL and beyond UCSF, or presence of all 3 risk factors, 46% recurrence). Acceptable long-term outcomes were achieved using our expanded selection criteria. Our prognostic model to predict recurrence based on preoperative biological and morphological factors could guide pretransplant management (downstaging versus upfront LDLT) with the aim of reducing post-LDLT recurrence.

RESUMEN

BACKGROUND: Cytomegalovirus (CMV) is the most common viral infection in liver transplant recipients that influences the outcomes of liver transplantation. However, its impact on early outcomes following living donor liver transplantation (LDLT) is not fully defined in the Indian subcontinent. This study was done to assess the impact of CMV infection on early post-transplant outcomes in LDLT recipients. METHODS: Out of 272 LDLTs performed from January 2012 to April 2013, 151 recipients underwent CMV viral load analysis in plasma within 90 days post LDLT based on clinical suspicion. Patients with CMV infection (n = 55) were compared with those without CMV infection (n = 96). RESULTS: The median time interval of CMV infection from LDLT was 25 days (range 2-90 days). The mean age of study population was 48.92 years. About 116 (76.8%) of the patients were male. Hepatitis C virus (HCV) (39.1%)-related chronic liver disease (CLD) was most common indication for liver transplant. No statistically significant difference was observed in etiology of liver disease (P = .38), Chid-Turcotte-Pugh (CTP) (P = .41), and Model for End-stage Liver Disease (MELD) (P = .12) scores between the groups. Patients with CMV infection had significantly higher incidence of acute cellular rejection (16.1% vs 5.4%, P = .02); longer ICU stay (P = .01); and a higher overall 90-day mortality (24.2% vs 6.7%, P = .001). Bacteremia and fungemia were significantly more common in the CMV infection group. CONCLUSION: Cytomegalovirus infection significantly influences the early post LDLT outcomes and contributes to increased overall mortality.

RESUMEN

MSUD occurs due to deficiency of enzyme BCKAD required for metabolism of leucine, isoleucine, and valine leading to the accumulation of these and their ketoacids causing acute metabolic decompensation manifesting as encephalopathy or sudden death. The patient requires special protein-restricted diet to survive. As this enzyme is expressed in liver, liver transplantation has been successfully performed as a cure. We report two patients of MSUD who underwent LDLT while their livers were used as a domino graft for other biliary cirrhotic patients. A 22-month-old male child diagnosed as a case of classic MSUD underwent LDLT from an altruistic aunt as donor following which his serum leucine levels normalized on an unrestricted protein diet. His liver was used as a domino graft. A 38-month-old female child with diagnosed MSUD underwent LDLT from a swap donor, and her liver was used as a domino graft. Her DQ improved post-transplant. LDLT from non-heterozygous donors is a cure for classical MSUD. Their livers can be used as domino grafts for non-MSUD cases.

RESUMEN

AIM: To evaluate the diagnostic implications of hepatic fat fraction calculated using dual-echo Dixon imaging and (1)H magnetic resonance spectroscopy (MRS) to detect hepatic steatosis in potential liver donors using histopathology as the reference standard. MATERIALS AND METHODS: One hundred and forty-five potential liver donors were included in the study. Magnetic resonance imaging (MRI) was performed using a 1.5 T system using a three-dimensional dual-echo MRI sequence with automated reconstruction of in-phase (IP), out-of-phase (OP), fat-signal-only, and water-signal-only images. Hepatic fat fraction was calculated by drawing 15 regions of interest on the IP, OP, fat-only, and water-only images. Single-voxel MRS was performed at echo times (TEs) of 30 ms in the right and left lobes of liver. Liver fat fraction was calculated from water and fat peaks. One hundred and forty-five biopsies were prospectively evaluated for steatosis by a pathologist using traditional determination of the cell-count fraction. MRI and pathology values of steatosis were correlated using Pearson's correlation coefficient. The sensitivity and specificity of each of these methods was calculated using histopathology as the reference standard. Reproducibility was assessed in 40 patients who had repeat scanning within 4-40 days. Measurement error was calculated from the coefficient of variation (CoV) with histopathologically proven <5% fat (n=112). RESULTS: The Bland-Altman limits of agreement with 95% confidence intervals (CI) was -2.9 to 5.3%. The intraclass correlation coefficient (ICC) for interobserver variability and reproducibility was 0.94 (95% CI: 0.91-0.97), 0.92 (95% CI: 0.91-0.97). The CoV was 7.6% (95% CI: 3.4-11.85). The area under the receiver operating characteristic (ROC) curve (AUC) for Dixon imaging 0.89 (95% CI: 0.87-0.91), for MRS 0.88 (95% CI: 0.86-0.90). The sensitivity for detecting <5% fat was 84% and specificity was 90%. CONCLUSION: Combination of dual-echo Dixon imaging and proton MRS is a useful tool for the preoperative diagnosis of hepatic steatosis in potential living liver donors. This can help avoid unnecessary biopsies in these patients.

RESUMEN

BACKGROUND: Low-dose hepatitis B immunoglobulin (HBIG) and nucleos(t)ides analogs (lamivudine/adefovir) used for the prevention of hepatitis B virus (HBV) recurrence after liver transplantation (LT) are associated with some risk of HBV recurrence and antiviral resistance. METHODS: The study cohort included 176 patients (at least >12 months follow-up) with HBV cirrhosis/hepatocellular carcinoma who received secondary prophylaxis with indefinite entecavir/tenofovir after living-donor LT (LDLT). All patients received 10,000 IU intravenous HBIG in anhepatic phase followed by 600-1000 IU intramuscularly daily for 7 days, weekly for 3 weeks, and then monthly, to keep antiHBs levels >100 mIU/mL for 1 year. Hepatitis B surface antigen (HBsAg) and HBV DNA were tested every 6 months. RESULTS: The study cohort is composed of 157 men and 19 women, mean age 47.9 ± 10.1 years, all HBsAg positive, 35 (19.8%) had HBV DNA >2000 IU/mL before LT. After LT, patients received entecavir (n = 126, 71.5%), tenofovir (n = 20, 11.3%), or a combination of entecavir and tenofovir (n = 30, 17% for 3 months), followed by entecavir alone. During follow-up of 43 (12-117) months, 2 patients (including 1 with non-compliance) had HBV recurrence. CONCLUSION: In a large cohort of LDLT recipients for HBV-related liver disease, use of low-dose short-term HBIG with high genetic barrier drugs results in a substantially lower incidence of HBV recurrence, even in high-risk patients.

RESUMEN

Congenital factor VII deficiency is an autosomal recessive serious disorder of blood coagulation with wide genotypic and phenotypic variations. The clinical presentation can vary from asymptomatic patients to patients with major bleedings in severe deficiency (factor VII <1%). Investigations show prolonged PT and low factor VII. Treatment modalities include FFP and repeated recombinant factor VII infusions. We hereby report the first successful LRLT for factor VII deficiency in an infant, the first-ever youngest baby reported worldwide. A six-month-old male child presented with easy bruisability, ecchymotic patches, hematuria, and convulsions. CT of the head showed subdural hemorrhage, which was treated conservatively. He had markedly increased PT (120 s) with normal platelets, and aPTT with factor VII level <1%. Despite the treatment by rFVIIa administration weekly, which was very expensive, he still had repeated life-threatening bleeding episodes. LRLT was performed with mother as the donor, whose factor VII level was 57%. A factor VII infusion plan for pre-, intra- and postoperative periods was formulated and TEG followed. Postoperatively, his factor VII started increasing from third day and was 38% on 24th day with PT <14 s. He had uneventful intraoperative and postoperative courses. LT is a safe and definite cure for factor VII deficiency.

RESUMEN

EBV-associated PTLD is increasingly recognized as an important cause of morbidity and mortality in both solid organ and hematopoietic stem cell transplant recipients. Mortality rates due to PTLD and virus-induced HLH are reported to be quite high. We report a case of EBV-associated PTLD and HLH in a child after liver transplantation who was successfully managed due to timely intervention. This case highlights that measurement of EBV load by quantitative polymerase chain reaction assays is an important aid in the surveillance and diagnosis of PTLD and early detection of EBV-induced PTLD, and aggressive treatment with rituximab is a key to survival in patients who have undergone liver transplantation.

RESUMEN

BACKGROUND AND AIMS: Early identification of non-response to steroids is critical in patients with autoimmune hepatitis (AIH) causing acute-on-chronic liver failure (ACLF). We assessed if this non-response can be accurately identified within first few days of treatment. METHODS: Patients with AIH-ACLF without baseline infection/hepatic encephalopathy were identified from APASL ACLF research consortium (AARC) database. Diagnosis of AIH-ACLF was based mainly on histology. Those treated with steroids were assessed for non-response (defined as death or liver transplant at 90 days for present study). Laboratory parameters, AARC, and model for end-stage liver disease (MELD) scores were assessed at baseline and day 3 to identify early non-response. Utility of dynamic SURFASA score [- 6.80 + 1.92*(D0-INR) + 1.94*(∆%3-INR) + 1.64*(∆%3-bilirubin)] was also evaluated. The performance of early predictors was compared with changes in MELD score at 2 weeks. RESULTS: Fifty-five out of one hundred and sixty-five patients (age-38.2 ± 15.0 years, 67.2% females) with AIH-ACLF [median MELD 24 (IQR: 22-27); median AARC score 7 (6-9)] given oral prednisolone 40 (20-40) mg per day were analyzed. The 90 day transplant-free survival in this cohort was 45.7% with worse outcomes in those with incident infections (56% vs 28.0%, p = 0.03). The AUROC of pre-therapy AARC score [0.842 (95% CI 0.754-0.93)], MELD [0.837 (95% CI 0.733-0.94)] score and SURFASA score [0.795 (95% CI 0.678-0.911)] were as accurate as ∆MELD at 2 weeks [0.770 (95% CI 0.687-0.845), p = 0.526] and better than ∆MELD at 3 days [0.541 (95% CI 0.395, 0.687), p < 0.001] to predict non-response. Combination of AARC score > 6, MELD score > 24 with SURFASA score ≥ - 1.2, could identify non-responders at day 3 (concomitant- 75% vs either - 42%, p < 0.001). CONCLUSION: Baseline AARC score, MELD score, and the dynamic SURFASA score on day 3 can accurately identify early non-response to steroids in AIH-ACLF.

RESUMEN

Background: Data on feasibility, management, and outcomes of liver transplantation (LT) in patients with pre-existing left ventricular systolic dysfunction (LVSD), severe coronary artery disease (CAD) or cirrhotic cardiomyopathy (CCM) is scarce. Methods: We reviewed outcomes of living donor liver transplantation (LDLT) in recipients with LVSD (ejection fraction [EF] < 50%) from our series of 1946 LDLT's performed between July 2010 and July 2018. Results: LVSD was detected in 12 male patients with a mean age, BMI and MELD of 52 ± 9 years, 25 ± 5 kg/m2, and 19 ± 4 respectively. Out of these, 6 patients had CAD (2 with previous coronary artery bypass graft, 1 following recent percutaneous transluminal coronary angioplasty, 2 post myocardial infarction, 1 noncritical CAD), and 6 had CCM. The EF ranged from 25% to 45%. Ethanol was the predominant underlying etiology for cirrhosis (50%). During LDLT, 2 patients developed ventricular ectopic rhythm and were managed successfully with intravenous lidocaine. Stress cardiomyopathy manifested in 3 patients post operatively with decreased EF, of which 2 improved, while 1 needed IABP support and succumbed to multiorgan failure on 8th postoperative day (POD). Another patient died on POD30 due to septic shock. Both these patients had higher MELD scores (actual MELD), extremes of BMI (17.3and 35.8 kg/m2) and were diabetic. There were no long-term cardiac deaths. The 1-year, and 5-year survival were 75%, and 66%, respectively. Conclusion: Among potential LT recipients with LVSD, those with stable CAD and good performance status, and well optimized CCM patients may be considered for LDLT after careful risk stratification in experienced centers.

RESUMEN

BACKGROUND: Using abdominal packs is often a life-saving technique for uncontrollable bleeding during operations. It prevents worsening of the hypothermia, coagulopathy and acidosis which usually accompanies massive bleeding till they may be corrected and the packs removed later. However, packing may be associated with a mortality of 56 to 82% due to continued bleeding, intra-abdominal abscesses and the compartment syndrome. We follow a policy of early abdominal packing (considering it after a 6 unit intraoperative blood loss) before the situation becomes irreversible. PATIENTS AND METHODS: Between January 1997 and September 2008, abdominal packing for uncontrollable bleed was done in 49 patients (M:F 34:15, mean age 43 years). The risk factors for mortality were analyzed. The reasons for uncontrollable bleed were: liver trauma (8), liver tumours (3), following liver transplantation (4), pancreatic necrosectomy (17) and miscellaneous causes (17). RESULTS: There were 16 postoperative deaths (32.7%). On univariate analysis, hypovolaemic shock, a low urine output, raised INR, blood requirement of more than 6 units, hypothermia <34 degrees C, metabolic acidosis and sepsis were associated with an increased mortality. However, on multivariate logistic regression only hypothermia was significantly associated with mortality. CONCLUSION: A fair survival rate can be achieved by early and judicious use of abdominal packing especially before hypothermia supervenes.

RESUMEN

BACKGROUND AND AIMS: COVID-19 is a dominant pulmonary disease, with multisystem involvement, depending upon comorbidities. Its profile in patients with pre-existing chronic liver disease (CLD) is largely unknown. We studied the liver injury patterns of SARS-Cov-2 in CLD patients, with or without cirrhosis. METHODS: Data was collected from 13 Asian countries on patients with CLD, known or newly diagnosed, with confirmed COVID-19. RESULTS: Altogether, 228 patients [185 CLD without cirrhosis and 43 with cirrhosis] were enrolled, with comorbidities in nearly 80%. Metabolism associated fatty liver disease (113, 61%) and viral etiology (26, 60%) were common. In CLD without cirrhosis, diabetes [57.7% vs 39.7%, OR = 2.1 (1.1-3.7), p = 0.01] and in cirrhotics, obesity, [64.3% vs. 17.2%, OR = 8.1 (1.9-38.8), p = 0.002] predisposed more to liver injury than those without these. Forty three percent of CLD without cirrhosis presented as acute liver injury and 20% cirrhotics presented with either acute-on-chronic liver failure [5 (11.6%)] or acute decompensation [4 (9%)]. Liver related complications increased (p < 0.05) with stage of liver disease; a Child-Turcotte Pugh score of 9 or more at presentation predicted high mortality [AUROC 0.94, HR = 19.2 (95 CI 2.3-163.3), p < 0.001, sensitivity 85.7% and specificity 94.4%). In decompensated cirrhotics, the liver injury was progressive in 57% patients, with 43% mortality. Rising bilirubin and AST/ALT ratio predicted mortality among cirrhosis patients. CONCLUSIONS: SARS-Cov-2 infection causes significant liver injury in CLD patients, decompensating one fifth of cirrhosis, and worsening the clinical status of the already decompensated. The CLD patients with diabetes and obesity are more vulnerable and should be closely monitored.

RESUMEN

Liver transplant recipients are prone to several infections, including lung infections, which can lead to substantial morbidity and mortality. Bronchoalveolar lavage (BAL) cytology is a rapid and sensitive diagnostic tool to identify the etiologic agents. We report a rare case of a 24-year-old male, post Live donor liver transplantation for autoimmune chronic liver disease, who presented with cough, fever, weight loss, and cavitatory lesion in lung. BAL cytology revealed Leishmania donovani (LD) and Pneumocystis jirovecii/carinii (PCP). Cytomegalovirus deoxyribonucleic acid polymerase chain reaction (CMV DNA PCR) test showed markedly raised levels. Patient was put on treatment for these multiple infections and showed significant improvement. Thus, rapid diagnosis of infections through BAL cytology is crucial in transplant recipients to institute timely therapy and avoid undesirable empirical treatments. Moreover, this case highlights a rare finding of LD bodies along with PCP in BAL cytology.

RESUMEN

The first consensus report of the working party of the Asian Pacific Association for the Study of the Liver (APASL) set up in 2004 on acute-on-chronic liver failure (ACLF) was published in 2009. With international groups volunteering to join, the "APASL ACLF Research Consortium (AARC)" was formed in 2012, which continued to collect prospective ACLF patient data. Based on the prospective data analysis of nearly 1400 patients, the AARC consensus was published in 2014. In the past nearly four-and-a-half years, the AARC database has been enriched to about 5200 cases by major hepatology centers across Asia. The data published during the interim period were carefully analyzed and areas of contention and new developments in the field of ACLF were prioritized in a systematic manner. The AARC database was also approached for answering some of the issues where published data were limited, such as liver failure grading, its impact on the 'Golden Therapeutic Window', extrahepatic organ dysfunction and failure, development of sepsis, distinctive features of acute decompensation from ACLF and pediatric ACLF and the issues were analyzed. These initiatives concluded in a two-day meeting in October 2018 at New Delhi with finalization of the new AARC consensus. Only those statements, which were based on evidence using the Grade System and were unanimously recommended, were accepted. Finalized statements were again circulated to all the experts and subsequently presented at the AARC investigators meeting at the AASLD in November 2018. The suggestions from the experts were used to revise and finalize the consensus. After detailed deliberations and data analysis, the original definition of ACLF was found to withstand the test of time and be able to identify a homogenous group of patients presenting with liver failure. New management options including the algorithms for the management of coagulation disorders, renal replacement therapy, sepsis, variceal bleed, antivirals and criteria for liver transplantation for ACLF patients were proposed. The final consensus statements along with the relevant background information and areas requiring future studies are presented here.

RESUMEN

BACKGROUND AND AIMS: Fast tracking (FT) for more efficacious use of resources may be difficult after living donor liver transplantation (LDLT) due to a partial liver graft, complex vascular anastomoses and longer operating time. Our study was aimed at reporting our experience with FT (on table extubation) in LDLT recipients. A secondary objective of our study was to look at defining a subgroup of patients who could be prospectively planned for FT. METHODS: We studied the demographics and outcomes of 15 LDLT recipients extubated immediately in the operating suite based on an uneventful intraoperative course, haemodynamic stability after graft reperfusion and improvement of metabolic parameters post-implantation and vascular anastomoses. RESULTS: Twelve recipients were males, and mean age, body mass index (BMI) and Model for End Stage Liver Disease (MELD) score were 43 ± 12 years, 23 ± 3 kg/m2 and 15.5 ± 6, respectively, most were Child-Turcotte-Pugh Class B. Diabetes and hypothyroidism were present in 1 and 2 patients, respectively. Post-extubation, none required immediate re-intubation and one patient needed non-invasive ventilation for 2 h. CONCLUSION: Fast tracked recipients were young, with a low BMI, low MELD scores, minimal comorbidities and good immediate graft function post-reperfusion.

RESUMEN

The world over, liver transplantation has emerged a panacea for thousands of patients suffering from end-stage liver disease. The strides made in living donor liver transplantation (LDLT) by Asian centres particularly in Japan, Korea, Hong Kong and Taiwan made many Indian centres realise that in order to sustain liver transplant activity in the country, a similar solution had to be found. Even though LDLT is very resource intensive and requires skilled multidisciplinary manpower, 22 centres in India have performed liver transplants, of which 14 have performed at least one LDLT procedure. 140 LDLT procedures have been performed at our centre, of which 13 have been done in emergency circumstances. LDLT has certain advantages over DDLT. It allows for adequate preparation of the patient for elective transplant and recipients are not in competition with others over the same donor organ. Major concerns with LDLT are of donor safety and biliary complications. In conclusion, establishing a high volume LDLT centre with excellent success rates is feasible in the Indian setting.

RESUMEN

INTRODUCTION: Robotic surgical system's ability to perform complex hepatobiliary surgeries is gaining momentum with outcomes similar to open surgery and advantages of minimal access surgery. The authors present their initial experience of a heterogenous spectrum of robotic hepatobiliary cases and the first reported case series from India. METHODS: Retrospective review of hepatobiliary cases done robotically from February 2015 to January 2016 was done. RESULTS: The series has ten patients; with median age of 45 years (range 15-72). Etiologies were choledochal cyst type IVa, benign lower end common bile duct stricture (biliary reconstruction group); incidental gallbladder carcinoma, hepatocellular carcinoma, recurrent pyogenic cholangitis, polycystic liver disease, hemangioma, liver metastases, hydatid cyst (resection group). Median operative duration was 510min; one patient needed intra-operative blood transfusion and there were no conversions to open surgery. One patient developed bile leak which was managed by biliary stenting and another thrombotic thrombocytopenic purpura during post-operative period. Median length of hospital stay was 6days with average cost of robotic surgery being $1700 USD more for major hepatectomy and $900 USD more for biliary reconstruction compared to open procedure. CONCLUSION: This initial series adds to existing data on the feasibility of robotic hepatobiliary cases with inherent advantages of minimal invasive surgery, however with limitation of availability and use of devices like cavitron ultrasonic surgical aspirator (CUSA) and higher operative cost.

RESUMEN

BACKGROUND: Malnutrition is an important risk factor for adverse outcomes in patients awaiting liver transplant. Living donor liver transplant, being an elective procedure, allows nutritional rehabilitation and optimization of these patients before transplant. AIM: This paper aimed to evaluate the outcome of end-stage liver disease (ESLD) patients with various degrees of malnutrition waiting for living donor liver transplant. METHODS: Nutritional status was assessed using subjective global assessment (SGA) in patients who were evaluated for a liver transplant at our center from January 2015 to September 2015. All the data were collected prospectively. Predictive factors for mortality were analyzed using logistic regression and survival was obtained using Kaplan-Meier curves. RESULTS: One hundred and seventeen patients were grouped based on their nutrition status into normal, mild-moderate, and severe malnutrition. The groups were comparable in terms of age, sex, etiology of liver disease except alcoholic liver disease. Graft recipient weight ratio was comparable among groups. There was no significant difference in hospital stay. However, severe malnourished patients had higher incidence of sepsis (p=0.005) and death due to sepsis (p=0.01). Nutritional status was the only independent predictor of mortality on multivariate analysis. CONCLUSION: Nutritional status measured with SGA independently predicts short-term outcome of ESLD patients waiting and after living donor liver transplant.

RESUMEN

OBJECTIVE: To describe our experience of pediatric living donor liver transplantation from India over a period of 12 years. MATERIALS AND METHODS: A retrospective analysis of 200 living donor liver transplantation in children (18 years or younger) was done for demographic features, indications, donor and graft profile and outcome. RESULTS: Between September 2004 and July 2016, 200 liver transplants were performed on 197 children. Fifty transplants were done in initial 6 years and 150 in next 6 years. All donors (51% mothers) were discharged with a mean stay of 7 days. The leading indications of liver transplants were cholestatic liver disease (46%) followed by metabolic liver disease (33%) and acute liver failure/acute on chronic liver failure (28.5%). Biliary leakage (8.5%), biliary stricture (9%), hepatic artery thrombosis (4.5%) and portal vein thrombosis (4%) were the most common surgical complications; all could be managed by surgical or interventional radiological measures, except in one child who died. Sepsis, acute rejection and CMV hepatitis in first 6 months were seen in 14.5%, 25% and 17% cases, respectively. Post-transplant lymphoproliferative disease was seen in only 1.5%. Re-transplant rate was 1.5%. The overall 1 year survival rate was 94% and 5 year actuarial survival was 87% with no statistically significant difference between children weight <10 kg vs. >10 kg. Outcome in acute liver failure did not differ significantly between those with acute on chronic liver failure vs. those with chronic liver disease. CONCLUSIONS: Advances in medical and surgical techniques associated with multidisciplinary teams including skilled pediatric liver transplant surgeons, anesthetists, dedicated pediatric hepatologists, pediatric intensivists, interventional radiologists and pathologists resulted in an excellent outcome of living related liver transplants in children. Low age and weight of the baby does not seem to be a contraindication for liver transplantation as outcome were comparable in our experience.
