The Model for End-Stage Liver Disease (MELD) scoring system, a validated objective liver disease severity scale, was adopted in February 2002 to allocate cadaveric organs for liver transplantation (LT). To improve transplantability before succumbing to advanced disease, patients with low-stage hepatocellular carcinoma (HCC) are given extra points in this system commensurate with their predicted mortality. Our aims were to determine 1) any change in the pathological findings at LT following the implementation of this system and 2) the impact of scoring advantage given to early-stage HCC. Clinicopathologic findings were compared before (pre-MELD, n = 87) and after (MELD, n = 58) the introduction of the MELD system. The findings in the pre-MELD vs. MELD groups were as follows: HCC, 27.5% vs. 48.3% (P = 0.001); portal vein thrombosis (PVT), 13.7% vs. 25.9% (P = 0.08); cholestasis, 16.1% vs. 32.7% (P = 0.026); inflammation grade of 2 or more, 43.7% vs. 48.3% (P = not significant); hepatitis C (HCV), 45.9% vs. 51.7% (P = not significant); HCV with lymphoid aggregates, 25% vs. 60% (P = 0.003); HCV with hyperplastic hilar nodes, 15.0% vs. 36.6% (P = 0.001); and post-LT HCC recurrence, 4.1% vs. 3.4% (P = not significant). Non-HCC-related findings were further compared in the 2 subgroups of pre-MELD (n = 57) and MELD (n = 31) after exclusion of HCC and fulminant hepatic failure (FHF) cases, and only cholestasis was significantly increased in the subgroup MELD. In conclusion, increased incidence of native liver cholestasis in the MELD era may be the histologic correlate of clinically severe liver disease. The scoring advantage given to low-stage HCC did result in a significantly increased incidence of HCC in the MELD group, but it did not adversely affect the post-LT recurrence rate.  相似文献

There has been a need to assess the "sickness degree" in patients with acute and chronic hepatic failure. The Model for End-Stage Liver Disease (MELD) score was developed as a tool for a more objective estimate of the "degree" of sickness in patients with chronic liver disease. In this study, the MELD score was retrospectively calculated and compared in adult patients accepted for orthotopic liver transplantation (OLT) in our institution in 1999 and 2004. We analyzed the gender, age, and MELD score associated with different indications for OLT during this period.  相似文献

目的 探讨终末期肝病模型(MELD)评分较高的良性终末期肝病患者的肝移植疗效.方法 回顾分析80例良性终末期肝病肝移植患者的资料,根据MELD评分的不同将患者分成两组,MELD评分≥30分的23例为高MELD评分组,MELD评分<30分的57例为低MELD评分组.分别比较两组患者手术时间、术中无肝期、术中血液制品输入量、术后重症监护病房(ICU)治疗时间和受者1年存活率,同时比较死亡患者和存活患者的临床资料,寻找导致术后死亡的危险因素.结果 高MELD评分组的手术时间、术中血液制品输入量、ICU治疗时间以及术后3个月内的死亡率明显高于低MELD评分组,差异有统计学意义(P<0.05),而术中无肝期和患者1年存活率,两组间的差异无统计学意义(P>0.05).死亡者和存活者相比较,MELD评分的差异无统计学意义(P>0.05),而术前机械通气、血清钠水平、持续性肝性脑病(重型)等方面的差异有统计学意义(P<0.05).结论 对于良性终末期肝病患者,单纯依靠MELD评分不足以准确判断患者肝移植术后的生存状态,高MELD评分者也可获得较好的肝移植结果,术前严重的低钠血症、重度肝性脑病以及机械通气是除MELD评分以外影响患者术后生存状况的危险因素.  相似文献

The objective of this study was to predict postoperative liver failure and morbidity after hepatectomy for hepatocellular carcinoma (HCC) with cirrhosis. The model for end-stage liver disease (MELD) score is currently accepted as a disease severity index of cirrhotic patients awaiting liver transplantation; however, its impact on prognosis after resection of HCC on cirrhosis has never been investigated. One hundred fifty-four cirrhotic patients resected in a tertiary care setting for HCC were retrospectively analyzed. For each patient, the MELD score was calculated and related to postoperative liver failure and complications (morbidity). Hospital stay and 1-year survival was also investigated. MELD accuracy in predicting postoperative liver failure and morbidity of cirrhotic patients was assessed using receiver operating characteristic (ROC) analysis. Eleven patients (7.1%) experienced postoperative liver failure leading to death or transplantation. ROC analysis identified cirrhotic patients with a MELD score equal to or above 11 at high risk for postoperative liver failure (area under the curve [AUC] = 0.92, 95% confidence interval [CI] = 0.87-0.96; sensitivity = 82%; specificity = 89%). Forty-six patients (29.9%) developed at least 1 postoperative complication: ROC analysis identified patients with a MELD score equal to or above 9 at major risk for postoperative complications (AUC = 0.85, 95% CI = 0.78-0.89; sensitivity = 87%; specificity = 63%). Cirrhotic patients with MELD score below 9 had no postoperative liver failure and low morbidity (8.1%). In conclusion, the MELD score can accurately predict postoperative liver failure and morbidity of cirrhotic patients referred for resection of HCC and should be used to select the best candidates for hepatectomy.  相似文献

Priority for liver transplantation is currently based on the Model for Endstage Liver Disease (MELD) score, a mathematical function which includes the following objective variables: bilirubin, creatinine (Cr), and international normalized ratio (INR). We have noted that specific laboratory methodologies may yield consistently higher values of bilirubin, Cr, and INR. Therefore, we performed a study to determine if higher MELD scores could be obtained by utilizing laboratory methodologies selected to return higher laboratory values than standard methodologies used in our hospital's clinical laboratory. Phlebotomy was performed for routine clinical indications in 29 consecutive patients listed for liver transplantation. MELD scores were calculated using bilirubin, Cr, and INR from laboratory methods in our hospital's clinical laboratory (designated Lab #1) and from 2 other clinical laboratories (designated Lab #2 and Lab #3). The mean MELD score in our hospital's clinical laboratory (Lab #1) (13.6) was not significantly different than in Lab #2 (14.7), but in Lab #3, it was significantly higher by 20% (17.1), P <.03. Virtually all of the difference in MELD score between our hospital's clinical laboratory (Lab #1) and Lab #3 could be attributed to the INR, which was significantly higher by 26% in Lab #3 (1.9) vs. Lab #1 (1.4), P <.00002. Using MELD scores calculated from our hospital's clinical laboratory, the average change in priority for liver transplantation was from the 58th percentile to the 77th percentile (compared to Lab #3), P =.01. In conclusion, patients listed for liver transplantation at our center achieved significantly higher MELD scores and therefore a higher priority for liver transplantation by using laboratory methodologies that yield higher INR values than our hospital laboratory. The selection of laboratory methodologies may have a significant impact on MELD score.  相似文献

Objective

The objective of this study was to analyze survival, and mortality, rates as well as its causes during the month following liver transplantation with respect to the model for end-stage liver disease (MELD) model.

Material and Methods

We reviewed the mortality at 24 and 48 hours as well as 1 and 4 weeks of 380 transplanted patients over the past 7 years with regard to the MELD score.

Results

The mean patient age was 55 years. Among subjects with MELD score ≤ 15 (n = 142; 37.36%), there were 34 deaths (23.94%), including 7 (4.92%) who died during the first month. The mean cause of death during this period was hemorrhage (n = 3; 8.8%). Among those with MELD scores between 16 and 18 (n = 76; 20%), the mortality rate increased to 23.68% (n = 18), including 3 who died during the first month (3.94%) with 1 case due to hemorrhage. Among the cohort with MELD scores between 19 and 21 (n = 78; 20.52%), 25 (32.05%) died, including 9 during the first month (11.53%). The most frequent cause of death was septic shock (n = 5; 20%). The mortality rate among patients with a MELD score between 22 and 24 was 22% (n = 11), of which 8% (n = 4) died in the month. The mean cause of death during this period was multiple organ dysfunction (n = 2; 18.1%). The patient group with a MELD score >24 had a 32.3% mortality rate (n = 11); 4 patients died during the first month following transplantation (11.76%). The most frequent cause of death was hemorrhage (n = 2; 18.1%).

Conclusions

Survival during the first month did not seem to be related to the MELD score at the time of transplantation, nor did we observe a direct correlation between the MELD score and the overall risk of mortality.  相似文献

The best prioritization of patients with hepatocellular carcinoma (HCC) waiting for liver transplantation under the model for end-stage liver disease (MELD) allocation system is still being debated. We analyzed the impact of a MELD adjustment for HCC, which consisted of the addition of an extra score (based on the HCC stage and waiting time) to the native MELD score. The outcome was analyzed for 301 patients with chronic liver disease listed for liver transplantation between March 1, 2001 and February 28, 2003 [United Network for Organ Sharing (UNOS)-Child-Turcotte-Pugh (CTP) era, 163 patients, 28.8% with HCC] and between March 1, 2003 and February 28, 2004 (HCC-MELD era, 138 patients, 29.7% with HCC). In the HCC-MELD era, the cumulative dropout risk at 6 months was 17.6% for patients with HCC versus 22.3% for those patients without HCC (P = NS), similar to that in the UNOS-CTP era. The cumulative probability of transplantation at 6 months was 70.3% versus 39.0% (P = 0.005), being higher than that in the UNOS-CTP era for patients with HCC (P = 0.02). At the end of the HCC-MELD era, 12 patients with HCC (29.3%) versus 57 without HCC (58.8%) were still on the list (P = 0.001). Both native and adjusted MELD scores were higher (P < 0.05) and progressed more in patients with HCC who dropped out than in those who underwent transplantation or remained on the list (the initial-final native MELD scores were 17.3-23.1, 15.5-15.6, and 12.8-14.1, respectively). The patients without HCC remaining on the list showed stable MELD scores (initial-final: 15.1-15.4). In conclusion, the present data support the strategy of including the native MELD scores in the allocation system for HCC. This model allows the timely transplantation of patients with HCC without severely affecting the outcome of patients without HCC.  相似文献

Recurrence of autoimmune liver disease in allografts has long been a topic of debate. We conducted a systematic review of the literature to examine the reported incidence of recurrence after liver transplantation of primary biliary cirrhosis (PBC), primary sclerosing cholangitis (PSC), and autoimmune hepatitis (AIH). The MEDLINE, EMBASE, and Cochrane electronic databases were used to identify articles. The inclusion criteria used were articles on patients with at least 90 days of posttransplantation follow-up, histologic criteria for diagnosis of PBC and AIH recurrence, radiologic or histologic criteria or both for diagnosis of PSC recurrence, and exclusion of other causes of liver disease causing similar histologic findings. Incidence in individual studies was combined to calculate the overall recurrence. Risk factors were analyzed whenever crude data were available. Funnel plots were used to assess publication bias. Out of 90 articles identified, 43 met criteria for systematic review (PBC, 16; PSC, 14; AIH, 13). The calculated weighted recurrence rate was 18% for PBC, 11% for PSC, and 22% for AIH. No difference was found in PBC and AIH recurrence by type of primary immunosuppression. There were not enough data to assess this issue in PSC studies. There was evidence of publication bias among PSC and AIH studies but not among PBC studies. In conclusion, recurrence of autoimmune liver disease after liver transplantation appears to be a real concern. As these patients are followed long-term, recurrence of disease may become the primary cause of morbidity.  相似文献

Abstract:
Objective To evaluate the effect of liver transplantation for end-stage autoimmune liver disease (ESALD) and summarize the clinical experience of liver transplantation in the treatment of ESALD.Methods The clinical data of 11 ESALD cases who underwent liver transplantation from September 2003 to July 2009 were analyzed retrospectively. There were 2 males and 9 females ( median age, 44. 2 ± 8. 7years). The indication of liver transplantation was end stage of primary biliary cirrhrosis (8 cases),autoimmune hepatitis (2 cases), and primary sclerosing cholangitis ( 1 case). In all cases, modified piggyback liver transplantation with venacavaplasty was carried out. Postoperatively all patients were treated with immunosuppressive agents including tacrolimus (or cyclosporine A) and prednisone, some patients were treated additionally with mycophenolate mofetil and ursodeoxycholic acid. Results Postoperatively 2patients of primary biliary cirrhosis died, one of lung infection and multiple organ failure on the 5th postoperative day, the other dying of sepsis and graft dysfunction on the 964th postoperative day. Five cases suffered from episodes of acute cellular rejection within 1 month after transplantation and was successfully reversed by strengthened immunosuppressive therapy. Nine patients recovered satisfactorily and with excellent life quality until now. Patients were followed up from 7 months to 62 months with the median follow-up time of 38 months. The recipient survival rate at 1 year and 3 years was 91% and 82% ,respectively. One patient has now survived for 5 years. No recurrent ALD case was found during follow up.Conclusions Orthotopic liver transplantation is an exclusive treatment for ESALD. Optimum operation timing and effective immunosuppressive treatment are very important for decreasing occurrence of complications.  相似文献

终末期肝病模型对肝移植术后生存率的预测   总被引:1,自引:0,他引:1  
目的探讨终末期肝病模型(model of end-stage liver disease,MELD)对良性终末期肝病肝移植患者生存率预测的价值。方法回顾性分析170例良性终末期肝病肝移植患者的临床资料,利用受试者工作特性曲线下面积(c-statistic值)评价MELD或Child-Turcotte-Pugh(CTP)评分预测患者肝移植术后生存时间的准确性。根据MELD值不同将患者分为3组:A组〈15,B组15~24和C组≥25,用Kaplan—Meier生存分析方法比较3组患者肝移植术后的生存率差别。结果MELD和CTP评分预测肝移植术后1、3、12个月生存率的c-statistic值分别为0.765和0.793、0.711和0.713、0.681和0.688。两者在同一时间的c-statistic值差异均无统计学意义。MELD评分与CTP评分有相关性(r=0.669,P=0.000)。A组和B组之间生存率差异无统计学意义(P=0.665),但C组生存率明显低于A组和B组,差异有统计学意义(分别为P=0.007和P=0.031)。结论MELD可以作为预测良性终末期肝病肝移植患者术后中、短期生存的指标,MELD≥25患者肝移植预后较差。MELD判断能力与CTP评分无明显差别。  相似文献

BACKGROUND/AIMS: The aim of this retrospective study is to analyze the prognostic impact of Model for End-Stage Liver Disease (MELD) score in patients undergoing liver transplantation (OLT) with suboptimal livers. METHODS: Between January 2002 and January 2006, 160 adult patients with liver cirrhosis received a whole liver for primary OLT at our institution including 81 with a suboptimal liver (SOL group) versus 79 with an optimal liver (group OL). The definition of suboptimal liver was: one major criterion (age >60 years, steatosis >20%) or at least two minor criteria: sodium >155 mEq/L, Intensive Care Unit stay >7 days, dopamine >10 microg/kg/min, abnormal liver tests, and relevant hemodynamic instability. RESULTS: Baseline recipients characteristics were comparable in the two study groups. The SOL group had a significantly greater number of early graft deaths (<30 days) than the OL group, while the 3-year Kaplan-Meier patient survivals were similar. Using logistic regression, MELD score was significantly related to patient death only in the SOL group (P = .01), and the receiver operator characteristics curve method identified 17 as the best MELD cutoff with the 3-year survival of 93% versus 85% for MELD < or =7 versus >17, respectively (P > 05). In comparison, it was 94% and 72% in the SOL group (P < .05). Similarly, MELD >17 was significantly associated with early graft death rates only in the SOL group. CONCLUSION: This study advised surgeons to not use suboptimal livers for patients with advanced MELD scores, thus supporting a donor-recipient matching policy.  相似文献

BACKGROUND: End-stage cholestatic liver disease (ESCLD) is the main indication for liver replacement in children. Pediatric cadaver-organ-donor shortage has prompted the most important evolutions in the technique of liver transplantation, in particular living-donor liver transplantation (LDLT) and split-liver transplantation (SLT). METHODS: Between November 1997 and June 2001, 127 children with ESCLD were evaluated for liver transplantation, and 124 underwent 138 liver transplantations after a median time of 40 days. Causes of liver disease were congenital biliary atresia (n=96), Alagille's syndrome (n=12), Byler's disease (n=8), and other cholestatic diseases (n=8). RESULTS: Ninety (73%) patients received a split-liver graft, 28 (23%) a whole liver, and 6 (4%) a reduced-size liver. Overall 2- and 4-year patient survival rates were 93% and 91%, respectively; the 2- and 4-year graft-survival rates were 84% and 80%, respectively. In split-liver recipients, 4-year patient and graft-survival rates were 91% and 83%, respectively; these were 93% and 78%, respectively, in whole-liver recipients and 67% and 63%, respectively, in reduced-size liver recipients. Retransplantation rate was 11%, whereas mortality rate was 8%. Overall incidence of vascular and biliary complication were 16% and 27%, respectively. CONCLUSIONS: SLT can provide liver grafts for children with ESCLD with an outcome similar to the one reported following LDLT, eliminating mortality while they are on a transplantation wait list. The need for pediatric LDLT should be reevaluated and programs of SLT strongly encouraged and supported at a national and international level.  相似文献

IntroductionSince the introduction of minimally invasive techniques, there is little agreement about use of laparoscopic surgery for malignant liver lesions as compared to open resection. We aim to analyse all available data comparing both these groups.MethodsAll the studies that compared laparoscopic and open liver resections for malignant lesions were searched on various databases. Data were collected and analysed in Review Manager RevMan (version 5.0).ResultsThere were total of 10 studies (n = 700) that compared laparoscopic (296/700) and open (404/700) hepatic resections for malignant lesions. Laparoscopic group was associated with reduced number of patients requiring blood transfusion [Odds ratio 0.35 CI 0.20, 0.60 P<0.001 HG 0.85], decreased number of positive resection margin [Odds ratio 0.34 CI 0.16, P0.006 HG 0.73] and decrease in overall complication rate [Odds ratio 0.43, CI 0.26, 0.73 P0.002 HG 0.22]. Laparoscopic group was associated with less operative blood loss [WMD 162.6 ml CI ?261.79, 73.45 P<0.001] and reduced hospital stay [WMD 4.28 days CI ?6.33, ?2.23 P<0.001]; however, there was significant heterogeneity [HG <0.001] between the studies for these parameters.ConclusionThe laparoscopic group was associated with reduce overall complication rate, positive resection margins and number of patients requiring blood transfusion. There is still need for level I and II data to compare laparoscopic versus open hepatic resection in malignant lesions.  相似文献

Adult-to-adult living donor liver transplantation (LDLT) for patients with decompensated end-stage liver disease (DELD) is controversial. Nevertheless, these patients are most in need of a timely liver transplant. We present the results of 7 patients who underwent transplantation with this procedure and discuss the rationale for its possible broader application. Seven of 51 patients who underwent right LDLT (segments 5 to 8) between August 1998 and April 2001 had DELD, defined as Child-Pugh-Turcotte score greater than 13 or Model for End-Stage Liver Disease score greater than 30. All patients also were listed for cadaveric liver transplantation. Mean age of the 7 transplant recipients was 54 years (range, 44 to 63 years). Three patients had ethyltoxic cirrhosis; 2 patients, hepatitis C; 1 patient, hepatitis B; and 1 patient, autoimmune hepatitis cirrhosis. The average intensive care unit stay was 23 days (range, 3 to 88 days), and average hospital stay was 77 days (range, 27 to 132 days). Three patients are alive 31, 21, and 17 months after LDLT. At a mean follow-up of 15.1 ± 10 months, patient and graft survival rates are 43%. Four transplant recipients died day 30, 60, 117, and 180 after transplantation. Three of the seven donors (43%) experienced a complication. At present, all donors are well and have returned to their normal activities. No donors had regrets about the procedure, and all donors stated that they would donate again if presented with the same decision. In conclusion, with the lack of other therapeutic options, LDLT represents a timely and effective alternative to cadaveric liver transplantation. Better outcome is foreseeable with a decrease in posttransplantation complications and more experience in predicting survival of these critical patients. (Liver Transpl 2002;8:340-346.)  相似文献
