Prevalence of anal HPV infection in solid-organ transplant patients prior to immunosuppression

Patients that undergo organ transplantation have a high risk of developing various malignancies, depending on the duration and magnitude of immunosuppressive therapy. Among others, a 10-fold increased relative risk has been reported for the development of anal cancer. There is a strong association between persistent infection with high-risk mucosal types of human papillomavirus (HPV) and anogenital neoplasia. In this study we analysed the prevalence of anal HPV infection in organ transplant patients before starting immunosuppressive therapy. In a university transplant unit, patients ( n=60, 40 male, 20 female) that were undergoing solid-organ transplantation (kidney, liver) for the first time were routinely screened for anal HPV infection. Anal swabs were obtained within 24 h after transplantation and analysed for the presence of mucosal-type HPV DNA by liquid DNA/RNA hybridization [hybrid capture (HC) 2 test]. Overall, some type of HPV DNA was detected in 14/60 (23.3%) patients; 9/60 (15%) were positive for high-risk HPV and 8/60 (13.4%) were positive for low-risk HPV, and 3/60 (5%) were positive for both types. Prevalence of HPV infection tended to be higher in patients that were receiving liver transplants than in those receiving kidney transplants (29.4% vs. 20.9%), but the difference did not reach statistical significance. In our series of organ transplant patients the prevalence of previous HPV infection (23.3%) before immunosuppressive therapy was started was higher than that found in previous epidemiological studies or in a control group. In particular, there was a high rate (15%) of infection with oncogenic HPV types. These findings have important implications on screening and surveillance policies in this patient group at risk of developing neoplasias, including anal cancer.

[Liver transplantation in elderly patients]

Since the first liver transplantation (OLT) was performed by Starzl in 1963, this has become the standard therapy for end stage chronic liver disease and acute hepatic failure. It is also the therapy of choice in selected cases of hepatic malignancy. Due to the optimization of intra- and perioperative management, new immunosuppressant drugs and improved organ procurement, the clinical outcome in patient and graft survival has increased continuously. The shortage of donor organs has led to the development of new surgical techniques such as split- and living related transplantation. OLT should also be offered to elderly patients. Careful evaluation and patient selection results in good patient and graft survival after transplantation, which is comparable to that in with younger recipients.

Biliary tract complications following liver transplantation

INTRODUCTION

Biliary tract complications, which occur in 5.8% to 24.5% of adult liver transplant recipients, remain one of the most common problems following transplantation. The aim of this study was to evaluate these problems and analyze methods of treatment.

MATERIAL AND METHODS

From 1989 to 2003, 36 (18.7%) among 193 patients who underwent orthotopic liver transplantations in our center developed biliary complications. Biliary strictures that developed in 18 cases (9.3%) were the most common complications. Clinical manifestations of strictures developed at 2 to 24 months after transplantation. Bile leaks occurred in 10 patients (5.2%), and were diagnosed in along the T-tube 4 cases and was not accompanied by any clinical manifestation. Bile leak to the peritoneum after T-tube removal occurred in 2 patients (1.1%). Solitary gallstone formation in one case (0.5%) was removed with the use of ECPW. One patient required retransplantation within 3 months after transplantation, because of the most severe complication-ischemic necrosis of biliary tract.

RESULTS

Uneventful recovery was achieved in 34 patients in the analyzed group (94.4%). There was no case of recurrence during outpatient follow up. Two patients died in late follow-up of unrelated causes: namely, gastrointestinal bleeding due to a duodenal ulcer and multi-organ failure (MOF) due to a third severe episode of acute liver transplant rejection.

CONCLUSIONS

Biliary complications remain an important problem in liver transplantation. Endoscopic and radiologic management are effective in the majority of cases. Surgical intervention is obligatory in selected cases.

Liver transplantation in Medellin, Colombia: Initial experience

OBJECTIVE

The goal of this article is to present the experience of a new liver transplant team.

MATERIALS AND METHODS

This review includes all patients who received a liver transplant between March 15, 2000 and March 15, 2003.

RESULTS

We performed 87 transplantations on 84 patients; 39 were females and 45 were males of average age 43.6 years, including 6 children. The majority of the patients were from Colombia with time on the waiting list of less than 1 month. The average donor age was 26.7 years. The preservation solutions included Wisconsin, HTK-Brettschneider (Custodiol), and Corpaúl (similar to Henn-Ross). In this study, 95.4% were whole livers, with 97.7% using the piggyback method. We placed 23 arterial grafts and 2 venous grafts for vascular reconstructions; 95.4% were duct-to-duct anastomosis (95.4%). Among the cohort, 8.3% experienced acute rejection and 1.2% experienced chronic rejection. Two patients required retransplantation due to hepatic artery thrombosis with biliary tree necrosis.

CONCLUSIONS

We consider that we have passed the crisis of beginning a new program with a reduction in postoperative complications and improving patient and graft survival. At present, we are a center that performs liver transplantations in adults and children, with a good organ donation culture in our city that allows us to offer a waiting time on the list less than one month. Neither a veno-venous bypass nor a T-tube were necessary for our cases. We also have developed a new, less expensive form of perfusing the liver in the donor.

Consumption of dietary supplements in a liver transplant population

The extensive use of alternative medicine products, herbal remedies, and vitamins in large doses has reached an all time high in the general public. Some agents are reported and advertised as immune stimulants and may interfere with patients suffering from immune modification, autoimmune diseases, or transplant recipients. In this report, we will present an investigation into the use of herbal remedies and vitamins in our liver transplant population. We performed an investigation using a questionnaire to determine the use of herbal products and vitamins in our liver transplant population. Medical records were reviewed for each liver transplant recipient that admitted to consuming herbal products or vitamins. Information collected included patient demographics, transplant related information, laboratory tests, outcomes, and herbs or vitamin products used. A total of 290 patients completed and returned the questionnaire. We found 156 admitting to taking more than a standard multivitamin and/or an herbal remedy. All patients were treated with steroids for allograft rejection and experienced a recurrence of amino transaminases following the removal of steroids. Further investigation into dietary supplements using a patient questionnaire form revealed that nearly 50% of patients admitted to using vitamins following transplantation, while 19% used herbal remedies combined with vitamins, most admitting to silymarin. One recipient was ingesting colostrum and required admission for the management of allograft rejection, while 5 patients had consumed large amounts of echinacea or CoEnzyme Q-10 and experienced elevations in their transaminases that resolved with discontinuation of the herb. The review also identified 4 patients with primary biliary cirrhosis and with transaminase elevation (mean values of aspartate aminotransferase and alanine aminotransferase levels of 88 and 95, respectively). All recipients were consuming vitamins, in particular high doses of vitamin E (tocopherol), more than 1 gram per day. All of the transplant recipients were instructed to discontinue all vitamin E products and the amino transaminases resolved over the following 30 to 60 days. In conclusion, this information reveals that a significant proportion of our liver transplant recipients consume herbal remedies. The results of this report suggest that transplant teams need to question each recipient about the use of herbal and vitamin remedies and educate them regarding the potential hazards.

Clinical characterization and survival of adult patients awaiting liver transplantation in Chile

Liver transplantation has become widely used for patients with decompensated disease. Because of the shortage of donors, each year more patients die on the waiting list. Our aim was to characterize and evaluate the final outcomes of all listed candidates for liver transplantation during a 34-month period. We retrospectively evaluated all adults listed between January 2000 and November 2002. Sixty-three patients (37 women, mean age 45.8 years) were listed: 48 due to chronic liver disease and 15 for a highly urgent transplantation due to acute liver failure. The main etiology of chronic disease was alcoholic (22%) or primary biliary cirrhosis (17%). Of 52 chronic patients, 26 (50%) were transplanted with a mean waiting time of 168 days. Among the others, 8 died (15%) while awaiting transplantation, 3 (5%) were removed from the list, and 15 patients still await transplantation (28%). Among acute liver failure patients, the main etiologies were autoimmune (25%) and medication induced (25%). Of 15 acute patients, 6 (37.5%) have been transplanted at a mean waiting time of 6.8 days with 100% survival posttransplantation. In this cohort, 6 patients (37.5%) died while awaiting liver transplantation, and 4 (25%) survived with medical support. In conclusion, the severity of liver disease and death rate among our waiting list was similar to that observed in developed countries. It seems reasonable to review our current allocation system based on waiting time on the list. We will have to decide whether to transplant sicker patients or those with hepatocarcinoma (as in the United States recently with the MELD system), thereby possibly decreasing the mortality rate on the waiting list at the expense of higher costs and more difficult postoperative care or to just keep our current policy.

Disparity in use of orthotopic liver transplantation among blacks and whites

Orthotopic liver transplantation (OLT) is the best treatment for end-stage liver disease. Limited data exist on the access of minorities to OLT. The aim of this study was to determine whether disparities exist among black and white OLT patients. Data were collected from the United Network for Organ Sharing on black and white 18-70 year-old OLT waiting list registrants (n = 29,013) and OLT recipients (n = 15,805) between 1994 and 1998. Standardized transplant ratios were generated by comparing the racial distribution of OLT patients with the US population. Demographic and clinical characteristics of OLT registrants were compared by race. Multivariate analyses were performed to identify predictors of time to OLT and the likelihood of dying or receiving OLT within 4 years, controlling for severity of illness and other factors. The standardized transplant ratio for black OLT recipients (0.65) was significantly lower than the standardized transplant ratio for white OLT recipients (1.05). Blacks were younger and sicker than whites. After adjustment for severity and other factors, time to OLT among recipients did not differ by race (P >.05). Blacks were more likely to die or become too ill for OLT while waiting (P <.001). Blacks were less likely to receive OLT within 4 years (P <.001). In conclusion, adult blacks were underrepresented among OLT patients. Although waiting times were similar once listed, black race affected outcomes while awaiting OLT. The process of referral and evaluation for OLT should be investigated further.

A comparison of disease severity and survival rates after liver transplantation in the United Kingdom, Canada, and the United States

The severity of preoperative liver disease influences the outcome of liver transplantation, is commonly used to determine priority on liver transplant waiting lists, and may differ between countries with different rates of liver disease and organ allocation systems. We compared the relative severity of liver disease in transplant recipients with chronic liver disease in the United States, Canada, and the United Kingdom and its relation to outcome. Data were obtained from national databases on patients who received transplants in the year 2000. The data included age, gender, diagnosis, the status at the time of transplantation, and indices of chronic liver disease [serum bilirubin and international normalized ratio (INR), and serum creatinine] from which a comparative score [model for end-stage liver disease (MELD) score] was calculated. The data revealed marked differences between the three countries. No patient in the United Kingdom was in intensive care before transplantation compared with 19.3% of recipients in the United States and 7.5% in Canada. The median model MELD score of recipients in the United Kingdom was 10.9 compared with 16.1 in the United States and 17 in Canada. The median MELD score of transplant recipients in North America did not vary according to diagnosis, whereas in the United Kingdom, patients with cholestatic liver disease had a lower median MELD score (8.5) than those with alcoholic liver disease (15.7) at the time of transplantation. In conclusion, the disease severity of UK liver transplant recipients varied by diagnosis and was lower than recipients in North America; the 1-year survival rate was, however, similar between the countries.

Pretransplant MELD score and post liver transplantation survival in the UK and Ireland

It has been shown that the model for end-stage liver disease (MELD) score is an accurate predictor of survival in patients with liver disease without transplantation. Four recent studies carried out in the United States have demonstrated that the MELD score obtained immediately prior to transplantation is also associated with post-transplant patient survival. Our aim was to evaluate how accurately the MELD score predicts 90-day post-transplant survival in adult patients with chronic liver disease in the UK and Ireland. The UK and Ireland Liver Transplant Audit has data on all liver transplants since 1994. We studied survival of 3838 adult patients after first elective liver transplantation according to United Network for Organ Sharing categories of their MELD scores (< or = 10, 11-18, 19-24, 25-35, > or =36). The overall survival at 90-days was 90.2%. The 90-day survival varied according to the United Network for Organ Sharing MELD categories (92.6%, 91.9%, 89.7%, 89.7%, and 70.8%, respectively; P < 0.01). Therefore, only those patients with a MELD score of 36 or higher (3% of the patients) had a survival that was markedly lower than the rest. As a consequence, the ability of the MELD score to discriminate between patients who were dead or alive was poor (c-statistic 0.58). Re-estimating the coefficients in the MELD regression model, even allowing for nonlinear relationships, did not improve its discriminatory ability. In conclusion, in the UK and Ireland the MELD score is significantly associated with post-transplant survival, but its predictive ability is poor. These results are in agreement with results found in the United States. Therefore, the most appropriate system to support patient selection for transplantation will be one that combines a pretransplant survival model (e.g., MELD score) with a properly developed post-transplant survival model.

[Symptoms of anxiety and depression in liver-transplant patients]

INTRODUCTION

We analyzed the influence of two variables (place of hospitalization of the patients and mental health of relatives) on anxiety and depression symptoms in liver-transplant patients.

METHODS

The subject groups were made up of 48 liver-transplant patients and 48 close relatives. The tests applied were a psychosocial questionnaire and the following instruments: The Hospital Anxiety and Depression Scale, The Leeds Scales for the Self-Assessment of Anxiety and Depression and Social Support Scale.

RESULTS

The liver-transplant patients showed more symptoms of depression when they were admitted in the Intensive Care Unit (ICU) and more symptoms of anxiety in the post-ICU phase when their close relatives were more depressed in that phase, as a result of receiving little social support.

CONCLUSIONS

The place of hospitalization of the patients and the mental health of relatives influenced symptoms of anxiety and depression in liver-transplant patients.

Studies of Pediatric Liver Transplantation: 2002 update. An overview of demographics, indications, timing, and immunosuppressive practices in pediatric liver transplantation in the United States and Canada

Studies of Pediatric Liver Transplantation (SPLIT) was initiated in 1995 for the purpose of collecting comprehensive data from children undergoing liver transplantation. As of May 31, 2002, 1761 children were registered in SPLIT from 38 participating centers in the United States and Canada. This report focuses on the demographics, primary diagnoses, clinical indications for transplant, and probability of obtaining liver transplantation for the 1187 children receiving a liver transplant after registration in SPLIT. Demographic information is also provided for the 1092 children who received their first ever liver transplantation. For this cohort, we also describe immunosuppressive practices at the time of transplant, and how the use of different medications changes with time.

Studies of Pediatric Liver Transplantation 2002: patient and graft survival and rejection in pediatric recipients of a first liver transplant in the United States and Canada

Studies of Pediatric Liver Transplantation (SPLIT) is a cooperative research network comprising 38 pediatric liver transplant centers in North America. Data from the 1092 patients who have received a first liver transplant since 1995 were analyzed for factors influencing patient survival, graft survival and acute rejection. The 3, 12, 24 and 36 month Kaplan-Meier estimates of patient/graft survival were 90.9/85.5, 86.3/80.2, 84.3/76.0, and 83.8/75.3% respectively. Univariate analysis identified initial diagnosis, type of graft (whole vs. living and cadaveric technical variant), growth failure and continuous hospitalization or ICU admission prior to transplantation as significantly influencing patient and graft survival. Subsequent multivariate analysis identified as risk factors for death: fulminant liver failure (RR = 3.05, p < 0.05), cadaveric technical variant grafts (RR = 1.95, p < 0.05), continuous hospitalization pre-transplant (RR = 1.79, p < 0.05), height deficit >2 s.d. from mean (RR = 3.22, p < 0.05). Risk factors for graft loss included: fulminant liver failure (RR = 2.27, p < 0.05), cadaveric technical variant grafts, (RR = 1.97, p < 0.05). Eleven percent of the 1092 patients were re-transplanted; vascular complications, particularly hepatic artery thrombosis (8.3% overall; 36.3% of graft failures), were responsible for the majority of re-transplants. Infection was the single most important cause of death (40 of 141, 28.4%) and was a contributing cause in 55 (39%), particularly with bacterial or fungal organisms. The cumulative Kaplan-Meier estimates of first rejection at 3, 12, 24 and 36 months were 44.8, 52.9, 59.1, and 60.3%. Initial immunosuppression with tacrolimus reduced the probability of rejection (RR = 0.62, p < 0.05). Eleven percent of rejections were steroid-resistant; chronic rejection led to 7 of 121 (5.8%) re-transplants. The SPLIT registry, in compiling data from a large number of centers, reflects the current outcomes for pediatric liver transplants in North America.

Biliary atresia--a fifteen-year review of clinical and pathologic factors associated with liver transplantation

PURPOSE

The aim of this study was to identify clinical and pathologic factors associated with liver transplantation in infants with biliary atresia initially treated with Kasai hepatic portoenterostomy (KHPE).

METHODS

Institutional Review Board approval was obtained. Records of patients with biliary atresia diagnosed between January 1986 and December 2000 were reviewed. Patients were divided into those who never required transplantation, those who underwent transplant in the first year after KHPE, and those who required transplantation later in childhood. Analysis of variance (ANOVA) compared multiple factors among the 3 groups. Proportional analysis compared those who required transplantation against those who did not. Statistical significance was considered achieved if P was less than.05.

RESULTS

Forty-five patients were identified. Survival after KHPE was 96% (43 of 45). Sixteen (37%) never required transplantation, 13 (30%) underwent transplant within 1 year after KHPE, and 14 (33%) underwent transplant more than 1 year after KHPE. ANOVA comparison showed that the duration of jaundice before KHPE as a predictor for liver transplantation approached significance (P =.082). Proportional analysis found that a longer initial duration of jaundice before KHPE (P =.016) and failure to establish biliary flow (P =.033) were also significant predictive factors. An initial requirement for phototherapy (P =.057) and ductules less than 200 microm in diameter (P =.060) showed a trend toward predictor of liver transplantation.

CONCLUSIONS

A longer duration of jaundice before KHPE, failure to establish bile flow, requirement for phototherapy in the neonatal period, and ductules smaller than 200 microm are associated with liver transplant after KHPE.

Association of center volume with outcome after liver and kidney transplantation

Outcomes for certain surgical procedures have been linked with volume: hospitals performing a high number of procedures demonstrate better outcomes than do low-volume centers. This study examines the effect of volume on hepatic and renal transplant outcomes. Data from the Scientific Registry of Transplant Recipients were analyzed for transplants performed from 1996-2000. Transplant centers were assigned to volume quartiles (kidney) or terciles (liver). Logistic regression models, adjusted for clinical characteristics and transplant center clustering, demonstrate the effect of transplant center volume quantile on 1-year post-transplant patient mortality (liver) and graft loss (kidney). The unadjusted rate of renal graft loss within 1 year was significantly lower at high volume centers (8.6%) compared with very low (9.6%), low (9.9%) and medium (9.7%) volume centers (p = 0.0014). After adjustment, kidney transplant at very low [adjusted odds ratio (AOR) 1.22; p = 0.043) and low volume (AOR 1.22 p = 0.041) centers was associated with a higher incidence of graft loss when compared with high volume centers. Unadjusted 1-year mortality rates for liver transplant were significantly different at high (15.9%) vs. low (16.9%) or medium (14.7%) volume centers. After adjustment, low volume centers were associated with a significantly higher risk of death (AOR 1.30; p = 0.0036). There is considerable variability in the range of failure between quantiles after kidney and liver transplant. Transplant outcomes are better at high volume centers; however, there is no clear minimal threshold volume.

Retransplantation of the liver in adults: outcome and predictive factors for survival

Hepatic retransplantation is considered to carry a higher risk than primary transplantation. Survival might improve with more experience and better immunosuppression. We studied all 55 patients who were adults at the time of their first retransplantation and who underwent retransplantation between 1979 and May 2001. Patient survival at 1, 5 and 10 years was 73%, 63%, and 63%, respectively. Multivariate analysis of pre-transplant variables revealed prothrombin time, creatinine level, and indication for retransplantation, as independent predictive factors. Survival was highest in patients who had undergone retransplantation for hepatic artery thrombosis. Multivariate analysis, including pre-, per-, and post-operative variables, showed that era of transplantation, prothrombin time, blood loss, and intensive care unit (ICU) stay, were independent predictive factors. Survival at 1 and 5 years improved from 56% and 48%, respectively, before 1996 to 89% and 81%, respectively, after 1996. In conclusion, survival after hepatic retransplantation improved significantly through the years. Independent pre-transplant predictive factors were prothrombin time, creatinine level, and indication for retransplantation.

REDUCED INCIDENCE OF HYPERURICEMIA, GOUT, AND RENAL FAILURE FOLLOWING LIVER TRANSPLANTATION IN COMPARISON TO HEART TRANSPLANTATION: A LONG-TERM FOLLOW-UP STUDY

BACKGROUND

Hyperuricemia and gout are common complications of heart transplantation, reaching a prevalence of 84% and 30%, respectively, in heart transplant recipients. In contrast, they are seldom reported following orthotopic liver transplantation (OLT).

METHODS

We retrospectively evaluated 75 consecutive liver transplant recipients and 47 consecutive heart transplant recipients, followed for at least 3 years after transplantation in a single transplantation center in Jerusalem, Israel. Data was collected on demographic and clinical variables, levels of uric acid, the occurrence of gout, renal function, and variables effecting hyperuricemia, such as weight and medications.

RESULTS

Clinical gout was significantly more prevalent in heart recipients than in liver recipients (25.5% and 2.6%, respectively). Hyperuricemia was present in 100% of heart recipients, with an average uric acid level of 451 micromol/l, as compared with 85.7% and 403 micromol/l for liver recipients (P < 0.001 for both variables). Univariate analysis identified several parameters which significantly influenced the difference in hyperuricemia and gout among the two groups including age, gender, rejection episodes, hypertension, diabetes mellitus, the level of uric acid prior to transplantation, and the use of cyclosporine A, diuretics, steroids, and aspirin. Use of tacrolimus and azathioprine were associated with decreased incidence of hyperuricemia and gout. Multivariate analysis identified the type of transplantation as the only independent risk factor predicting the development of hyperuricemia and gout.

CONCLUSION

Clinical gout and hyperuricemia were significantly more prevalent in heart recipients than in liver recipients. The disparity can be explained by differences in age, gender and renal function among the groups, as well as by the use of different medication regimens.

How well do members of the public deal with a distributive justice problem in health care?

OBJECTIVES

There is some debate about the appropriateness of involving the general public in decisions concerning the prioritising and rationing of health care resources. Doubt has been expressed about the public's ability to deal with these issues in a fair and rational way without taking refuge in ready-made official ideologies. This study considers the quality of discussion achieved by members of the public on this issue in terms of their ability to recognise the validity of conflicting arguments, to cope with the shifting positions created by these conflicts, and to avoid opting for simplistic ready-made solutions. It also records the participants' own perceptions of the quality of their discussion.

METHODS

Four focus groups were recruited through community organisations in a suburban area of Derby, and were asked to evaluate criteria for the rationing of donor livers for transplantation, relating this to specific patient profiles. Discussions were recorded, transcribed and analysed using qualitative methods.

RESULTS

Three groups showed an ability to work with shifting and conflicting arguments on most issues they discussed, but two of these groups showed a tendency to adopt simplistic solutions on one specific issue. The fourth group adopted a clear-cut solution to the main issues early on, and adhered to it for the rest of the discussion.

CONCLUSION

The overall performance of the groups suggests that rational and open public discussion can be achieved, but that participants may need support in avoiding premature adoption of simplistic solutions.

Developing a Brief Monitoring Procedure for Alcohol-Dependent Liver Graft Recipients

To address the occurrence of deaths in later postoperative years among alcohol-dependent liver graft recipients, the authors developed the Brief Active Focused Follow-Up protocol as an instrument for monitoring alcohol use following liver transplant. In this preliminary study, patient receptiveness to its use was tested and its ability to identify patient drinking was noted. Alcohol-dependent liver transplant recipients (N=24) and alcohol-dependent nontransplant patients (N=25) were asked to rate their receptiveness to the Brief Active Focused Follow-Up in three areas. Subjects used a five-point scale for which 5 indicated the highest positive response. Liver transplant recipients responded positively to the Brief Active Focused Follow-Up, with mean responses of 4.92, 4.08, and 4.63 with regard to clarity, usefulness, and ease of completion, respectively. Nontransplant subjects responded similarly, with mean responses of 4.88, 4.12, and 4.52. The two groups were not significantly different in their receptiveness to the Brief Active Focused Follow-Up interview. The Brief Active Focused Follow-Up identified alcohol use within the last 30 days: 8% (N=2 of 24) in the transplant group, and 56% (N=14 of 25) in the nontransplant group. These results suggest that 1) this manualized, brief monitoring technique is well received by alcohol-dependent liver transplant patients, and 2) the Brief Active Focused Follow-Up's "user friendliness" makes it a potentially appropriate instrument for long-term monitoring of alcohol use among alcohol-dependent liver graft recipients.

Results of 60 consecutive hepatectomies for pediatric living donor liver transplantation

Several technical improvements have been made to increase donor pool for pediatric liver transplantation, including reduced-size grafts, split-liver, and recently living donors. The objective of the present study is to report our single-center experience with 60 hepatectomies for living donor liver transplantation in pediatric recipients between June 2000 and December 2002. Donor workup consisted of a complete history and physical examination followed by laboratory test and liver function tests. Graft size was estimated using computed tomography scan or abdominal ultrasound. Liver biopsy was performed in all donors. Arteriogram was performed to evaluate hepatic arterial anatomy. All donors survived the procedure. Only seven patients experienced complications (10.2%), most of which were short term. We conclude that liver living donation for pediatric population is a safe procedure.
