Abstract Background There is currently limited information regarding the prognostic ability of the dNLR-PNI (the combination of the derived neutrophil-to-lymphocyte ratio [dNLR] and prognostic nutritional index [PNI]) for hepatocellular carcinoma (HCC). This study aimed to assess the predictive ability of the dNLR-PNI in patients with intermediate-to-advanced HCC after transarterial chemoembolization (TACE). Methods A total of 761 HCC patients were enrolled in the study. The dNLR-PNI was retrospectively calculated in these patients, as follows: patients with both an elevated dNLR and a decreased PNI, as determined using the cutoffs obtained from receiver operating characteristic curve analysis, were allocated a score of 2, while patients showing one or neither of these alterations were allocated a score of 1 or 0, respectively. Results During the follow-up period, 562 patients died. Multivariate analysis suggested that elevated total bilirubin, Barcelona Clinic Liver Cancer C stage, repeated TACE, and dNLR-PNI were independently associated with unsatisfactory overall survival. The median survival times of patients with a dNLR-PNI of 0, 1, and 2 were 31.0 (95% confidence interval [CI] 22.5–39.5), 16.0 (95% CI 12.2–19.7) and 6.0 (95% CI 4.8–7.2) months, respectively (P

Chronic liver allograft dysfunction (CLAD) remains the most common cause of patient morbidity and allograft loss in liver transplant patients. However, the pathogenesis of CLAD has not been completely elucidated. By establishing rat CLAD models, in this study, we identified the informative CLAD-associated genes using isobaric tags for relative and absolute quantification (iTRAQ) proteomics analysis and validated these results in recipient rat liver allografts. CXCL4, CXCR3, EGFR, JAK2, STAT3, and Collagen IV were associated with CLAD pathogenesis. We validated that CXCL4 is upstream of these informative genes in the isolated hepatic stellate cells (HSC). Blocking CXCL4 protects against CLAD by reducing liver fibrosis. Therefore, our results indicated that therapeutic approaches that neutralize CXCL4, a newly identified target of fibrosis, may represent a novel strategy for preventing and treating CLAD after liver transplantation.

Background. Living donor liver transplantation (LDLT) for patients with high model for end-stage liver disease (MELD) scores is controversial due to its poor outcome. However, there is little information regarding which factor would negatively impact the outcome of patients with high MELD scores. The aim of this study was to identify factors associated with the in-hospital mortality of patients with high MELD scores after LDLT.Material and methods. All patients with an MELD scores ≥ 20 who received LDLT from 2005 to 2011 were recruited for the present study. Pre-and intra-operative variables were retrospectively and statistically analyzed. Results. A total of 61 patients were included in the current study. The overall 3-month survival rate was 82% for patients with high MELD scores. Preoperative renal dysfunction, hyponatremia, starting albumin level < 2.8 g/dL, preoperative renal replacement for severe renal failure, anhepatic period > 100 minutes and intraoperative red blood cell (RBC) transfusion ≥ 10 units were identified as potential risk factors by univariate analysis. However, only hyponatremia, preoperative dialysis and massive RBC transfusion were independent risk factors in a multivariate analysis. The 3-month survival rates of patients with two or more independent risk factors and patients with none or one risk factor were 91 and 25%, respectively. A significant difference was observed (P < 0.001).Conclusion. Hyponatremia, preoperative dialysis and massive RBC transfusion were related to poor outcome for sicker patients. Patients with two or more of the above-mentioned risk factors and high MELD scores may exhibit extremely poor short-term survival.

Physics ,QC1-999 - Abstract
To determine the force mechanism for the steel plate shear wall with slits, the pushover analysis method was used in this study. An estimated equation for the lateral bearing capacity which considered the effect of edge stiffener was proposed. A simplified elastic-plastic analytical model for the stiffened steel slit wall composed of beam elements was presented, where the effects of edge stiffeners were taken into account. The wall-frame analysis model was established, and the geometric parameters were defined. Pushover analysis of two specimens was carried out, and the analysis was validated by comparing the results from the experiment, the shell element model, and a simplified model. The simplified model provided a good prediction of the lateral stiffness and the strength of the steel slit wall, with less than 10% error compared with the experimental results. The mutual effects of the bearing wall and the frame were also predicted correctly. In the end, the seismic performance evaluation of a steel slit wall-frame structure was presented. The results showed that the steel slit wall could prevent the beams and columns from being damaged by an earthquake and that the steel slit wall was an efficient energy dissipation component.

PURPOSE: This study is to evaluate the Hangzhou criteria (HC) for patients with HCC undergoing surgical resection and to identify whether this staging system is superior to other staging systems in predicting the survival of resectable HCC. METHOD: 774 HCC patients underwent surgical resection between 2007 and 2009 in West China Hospital were enrolled retrospectively. Predictors of survival were identified using the Kaplan-Meier method and the Cox model. The disease state was staged by the HC, as well as by the TNM and BCLC staging systems. Prognostic powers were quantified using a linear trend χ2 test, c-index, and the likelihood ratio (LHR) χ2 test and correlated using Cox's regression model adjusted using the Akaike information criterion (AIC). RESULTS: Serum AFP level (P = 0.02), tumor size (P

Immunologic diseases. Allergy ,RC581-607 - Abstract
Despite advances in immunosuppressive drugs, long-term success of liver transplantation is still limited by the development of chronic liver allograft dysfunction. Although the exact pathogenesis of chronic liver allograft dysfunction remains to be established, there is strong evidence that chemokines are involved in organ damage induced by inflammatory and immune responses after liver surgery. Chemokines are a group of low-molecular-weight molecules whose function includes angiogenesis, haematopoiesis, mitogenesis, organ fibrogenesis, tumour growth and metastasis, and participating in the development of the immune system and in inflammatory and immune responses. The purpose of this review is to collect all the research that has been done so far concerning chemokines and the pathogenesis of chronic liver allograft dysfunction and helpfully, to pave the way for designing therapeutic strategies and pharmaceutical agents to ameliorate chronic allograft dysfunction after liver transplantation.

AIM: The selection criteria for patients with hepatocellular carcinoma (HCC) to undergo liver transplantation should accurately predict posttransplant recurrence while not denying potential beneficiaries. In the present study, we attempted to identify risk factors associated with posttransplant recurrence and to expand the selection criteria. PATIENTS AND METHODS: Adult patients with HCC who underwent liver transplantation between November 2004 and September 2012 at our centre were recruited into the current study (N = 241). Clinical and pathological data were retrospectively reviewed. Patients who died during the perioperative period or died of non-recurrence causes were excluded from this study (N = 25). All potential risk factors were analysed using uni- and multi-variate analyses. RESULTS: Sixty-one recipients of 216 qualified patients suffered from recurrence. Similar recurrence-free and long-term survival rates were observed between living donor liver transplant recipients (N = 60) and deceased donor liver transplant recipients (N = 156). Total tumour volume (TTV) and preoperative percentage of lymphocytes (L%) were two independent risk factors in the multivariate analysis. We propose a prognostic score model based on these two risk factors. Patients within our criteria achieved a similar recurrence-free survival to patients within the Milan criteria. Seventy-one patients who were beyond the Milan criteria but within our criteria also had comparable survival to patients within the Milan criteria. CONCLUSIONS: TTV and L% are two risk factors that contribute to posttransplant recurrence. Selection criteria based on these two factors, which are proposed by our study, expanded the Milan criteria without increasing the risk of posttransplant recurrence.

Postoperative oral antiviral treatment with nucleoside or nucleotide analogues can suppress viral replication and reduce tumour recurrence for patients with hepatitis b virus–related hepatocellular carcinoma (HBV-related HCC) after curative resection. However, the superior antiviral treatment is still unclear. We conducted this study to investigate the different effects of nucleotide and nucleoside analogues on the prognosis of HBV-related HCC after curative resection. From February 2007 to February 2016, 487 consecutive patients with newly diagnosed HCC according to the Milan criteria who underwent R0 resection were enrolled according to the inclusion and exclusion criteria. According to their postoperative antiviral treatment, they were divided into the nucleotide group (NtA, n = 111) and the nucleoside group (NsA, n = 376). The baseline characteristics, serologic parameters, tumour characteristics, and operative data of the 2 groups were comparable. Nucleotide analogue use significantly decreased HCC recurrence (P = 0.028) and HCC-related death (P = 0.004), with hazard ratios (HRs) of 0.685 (95% CI, 0.484 to 0.971, P = 0.033) and 0.507 (95% CI, 0.310 to 0.830, P = 0.004), respectively, in multivariate Cox analyses. After the study patients were stratified according to three variables, we found that nucleotide analogue use was significantly associated with increased disease-free and overall survival among patients with cirrhosis, HBeAg-negative patients, and patients with positive HBV-DNA. In patients with HBV-related HCC, nucleotide analogues but not nucleoside analogues significantly reduced HCC recurrence and improved overall survival after R0 hepatic resection.

Whether hepatic resection (HR) combined with radiofrequency ablation (RFA) or HR alone is the treatment of choice for early or moderately advanced multifocal hepatocellular carcinomas (HCCs) is a matter of debate. This study compared the short- and long-term outcomes of patients with multifocal tumors meeting the University of California San Francisco (UCSF) criteria after HR plus intraoperative RFA or HR alone. A total of 261 consecutive patients with multifocal HCCs meeting the UCSF criteria from January 2010 to January 2018, who underwent combined treatment (n = 51) or HR (n = 210), were included. Propensity score matching was performed to adjust for baseline differences. Overall survival (OS) and recurrence-free survival (RFS) were calculated, and subgroup analysis, along with univariate and multivariate analyses, were performed. The 1-, 3-, and 5-year OS rates after combined treatment or HR alone were 86.3%, 66.6%, and 34.2%, and 92.8%, 67.1%, and 37%, respectively (p = 0.423); combined treatment provided similar RFS rates as HR at 1, 3, and 5 years (78.4%, 35.8% and 20.9% vs. 82.6%, 50.4% and 24.5%, respectively; p = 0.076). The propensity matching model showed similar results. Subgroup analysis showed that HR was associated with better RFS than HR plus RFA for patients with two tumors or major tumors ≤ 3 cm. Multivariate analysis revealed that portal hypertension and three tumors are independent risk factors. For multifocal HCC patients meeting the UCSF criteria, combined treatment may offer similar OS and RFS as HR; however, HR may be more suitable than combined treatment for patients with two tumors or major tumors ≤ 3 cm.

Background Given the shortage of suitable liver grafts for liver transplantation, proper use of hepatitis B core antibody-positive livers might be a possible way to enlarge the donor pool and to save patients with end-stage liver diseases. However, the safety of hepatitis B virus core antibody positive (HBcAb+) donors has been controversial. Initial studies were mainly conducted overseas with relatively small numbers of HBcAb+ liver recipients, and there are few relevant reports in the population of mainland China. We hypothesized that the safety of HBcAb+ liver grafts is not suboptimal. Aim To evaluate the safety of using hepatitis B virus (HBV) core antibody-positive donors for liver transplantation in Chinese patients. Methods We conducted a retrospective study enrolling 1071 patients who underwent liver transplantation consecutively from 2005 to 2016 at West China Hospital Liver Transplantation Center. Given the imbalance in several baseline variables, propensity score matching was used, and the outcomes of all recipients were reviewed in this study. Results In the whole population, 230 patients received HBcAb+ and 841 patients received HBcAb negative (HBcAb-) liver grafts. The 1-, 3- and 5-year survival rates in patients and grafts between the two groups were similar (patient survival: 85.8% vs 87.2%, 77.4% vs 81.1%, 72.4% vs 76.7%, log-rank test, P = 0.16; graft survival: 83.2% vs 83.6%, 73.8% vs 75.9%, 70.8% vs 74.4%, log-rank test, P = 0.19). After propensity score matching, 210 pairs of patients were generated. The corresponding 1-, 3- and 5-year patient and graft survival rates showed no significant differences. Further studies illustrated that the post-transplant major complication rates and liver function recovery after surgery were also similar. In addition, multivariate regression analysis in the original cohort and propensity score-matched Cox analysis demonstrated that receiving HBcAb+ liver grafts was not a significant risk factor for long-term survival. These findings were consistent in both HBV surface antigen-positive (HBsAg+) and HBsAg negative (HBsAg-) patients.Newly diagnosed HBV infection had a relatively higher incidence in HBsAg- patients with HBcAb+ liver grafts (13.23%), in which HBV naive recipients suffered most (31.82%), although this difference did not affect patient and graft survival (P = 0.50 and P = 0.49, respectively). Recipients with a high HBV surface antibody (anti-HBs) titer (more than 100 IU/L) before transplantation and antiviral prophylaxis with nucleos(t)ide antiviral agents post-operation, such as nucleos(t)ide antiviral agents, had lower de novo HBV infection risks. Conclusion HBcAb+ liver grafts do not affect the long-term outcome of the recipients. Combined with proper postoperative antiviral prophylaxis, utilization of HBcAb+ grafts is rational and feasible.

This retrospective study was conducted to examine the development and current status of pediatric liver transplantation (LT) in western China. Clinical, demographic, morbidity, and mortality data were collected to analyze. It included 260 consecutive pediatric LTs performed at three centers in western China between January 2000 and May 2019. Kaplan-Meier graft survival rates at 1, 3, 5, and 10 years were 82.1%, 77.2%, 76.6%, and 76.6%, respectively; corresponding patient survival rates were 84.7%, 80.7%, 80.0%, and 80.0%, respectively. More patients underwent living donor liver transplantation (LDLT; n = 188 (73.4%)) than deceased-donor liver transplantation (DDLT; n = 68 (26.6%)). Survival was better after LDLT (91.5%, 86.6%, and 80.6% at 1, 3, and 5 years, respectively) than after DDLT (80.9%, 72.4%, and 63.9%, respectively; P < .05). Biliary atresia was the leading LT indication (n = 141 (55.1%)), followed by metabolic disease (n = 36 (14.1%)), which was associated with the best recipient survival (88.5% at 5 years). The transplant era and graft-to-recipient body weight ratio (GRWR) also significantly predicted overall survival. Survival rates at 5 years were worst in 2000-2005 (54.5%) and best for GRWRs of 0.8%-4% (80.4%). The development of pediatric LT in western China began slowly, but the quantity and quality of pediatric LT has progressed in recent years. This procedure is now a promising and reliable treatment for children with end-stage liver disease in western China.

How much difference there is between hepatic resection (HR) combined with intraoperative radiofrequency ablation (RFA) and living donor liver transplantation (LDLT) in treatment of multifocal hepatocellular carcinomas (HCCs) remains unclear. This study compared outcomes for patients with multifocal HCCs meeting the University of California San Francisco (UCSF) criteria treated by LDLT or HR + RFA. A total of 126 consecutive Child–Pugh A patients with multifocal HCCs meeting the UCSF criteria, who underwent LDLT (n = 51) or HR + RFA (n = 75), were included. Propensity score (PS) matching was performed to adjust for baseline differences. Overall survival (OS) and recurrence-free survival (RFS) were calculated, and subgroup, multivariate and nomogram analyses were performed. LDLT provided significantly better OS and RFS than did HR + RFA before and after PS matching and reduced the dropout rate on waiting list, but HR + RFA was more convenient, less invasive and less cost. Patients with all lesions located in the same lobe had better OS and RFS than those located in the different lobes after HR + RFA. Multivariate and nomogram analyses revealed that HR + RFA, alpha-fetoprotein ≥ 400 ng/mL, the major tumour size > 3 cm and microvascular invasion were independent predictors of poor prognosis. For Child–Pugh A patients with multiple HCCs meeting the UCSF criteria, LDLT may offer significantly better long-term results than did HR + RFA, and HR + RFA may still be considered as an acceptable curative therapy for those without considering transplantation or as a bridge treatment for a patient, with a plan for transplantation in the future.

Objective To assess the value of hepatic resection by comparing it with transarterial chemoembolization for hepatocellular carcinoma beyond the Milan criteria with clinically relevant portal hypertension. Methods A total of 363 patients and 193 propensity score-matched patients who had hepatocellular carcinoma beyond the Milan criteria with clinically relevant portal hypertension and underwent hepatic resection or transarterial chemoembolization were retrospectively analyzed. The short-term and long-term results were compared. Results Postoperative complications and 30-day mortality were similar between the two groups. The hepatic resection provided a survival benefit over TACE at 1, 2, 3, and 5 years. Similar results were observed in the propensity score analysis. Five variables were identified as independent prognostic factors: treatment, AFP, Child–Pugh classification, tumor number and extension of disease in a multivariate analysis of the whole study population. In addition, only the tumor number was identified as an independent risk factor after propensity matching. The subgroup analysis demonstrated that the survival benefit of the hepatic resection can only be derived in a subset of patients with a single tumor. Conclusions In a properly selected group of patients with hepatocellular carcinoma beyond the Milan criteria with clinically relevant portal hypertension, hepatic resection appears to be as safe as TACE and provides a significant survival benefit.

Many studies have confirmed that serum total cholesterol (sTC) concentrations were associated with underlying liver damage and the synthesis capacity of liver. However, the role of postoperative sTC level on evaluating graft function and predicting survival of recipients who underwent liver transplantation has not been discussed.Clinical data of 231 living donor liver transplantation recipients from May 2003 to January 2015 were retrospectively collected. Patients were stratified into the low sTC group (sTC1.42 mmol/L, 57 recipients) and high sTC group (sTC =1.42 mmol/L, 174 recipients) according the sTC level on postoperative day 3 based on receiver-operating characteristic curve analysis. The clinical characteristics and postoperative short- and long-term outcomes were compared between the two groups.Recipients with sTC1.42 mmol/L experienced more severe preoperative disease conditions, a higher incidence of postoperative early allograft dysfunction (38.6% vs 10.3%, P0.001), 90-day mortality (28.1% vs 10.9%, P=0.002) and severe complications (29.8% vs 17.2%, P=0.041) compared to recipients with sTC =1.42 mmol/L. The multivariate analysis demonstrated that sTC1.42 mmol/L had a 4.08-fold (95% CI: 1.83-9.11, P=0.001) and 2.72-fold (95% CI: 1.23-6.00, P=0.013) greater risk of developing allograft dysfunction and 90-day mortality, and patients with sTC1.42 mmol/L had poorer overall recipient and graft survival rates at 1-, 3-, and 5-year than those with sTC =1.42 mmol/L (67%, 61% and 61% vs 83%, 71% and 69%, P=0.025; 65%, 59% and 59% vs 81%, 68% and 66%, P=0.026, respectively). Cox multivariate analysis showed that sTC1.42 mmol/L was an independent predicting factor for total recipient survival (HR=2.043; 95% CI: 1.173-3.560; P=0.012) and graft survival (HR=1.905; 95% CI: 1.115-3.255; P=0.018).sTC1.42 mmol/L on postoperative day 3 was an independent risk factor of postoperative early allograft dysfunction, 90-day mortality, recipient and graft survival, which can be used as a marker for predicting postoperative short- and long-term outcomes.

Albumin–bilirubin (ALBI) grade has been validated as a simple, evidence-based, and objective prognostic tool for patients with hepatocellular carcinoma (HCC). However, minimal information is available concerning postoperative ALBI grade changes in HCC. This study aimed to investigate the prognostic value of postoperative ALBI grade changes in patients with hepatitis B virus (HBV)-related HCC within the Milan criteria after liver resection. Patients with HBV-related HCC within the Milan criteria who underwent liver resection between 2010 and 2016 at West China Hospital were reviewed (N = 258). A change in ALBI grade was defined as first postoperative month ALBI grade–preoperative ALBI grade. If the value was >0, postoperative worsening of ALBI grade was considered; otherwise, stable ALBI grade was considered. Cox proportional hazard regression analyses were used to determine the factors that influence recurrence and survival. During the follow-up, 130 patients experienced recurrence and 47 patients died. Multivariate analyses revealed that postoperative worsening of ALBI grade (HR 1.541, 95% CI 1.025–2.318, P = 0.038), microvascular invasion (MVI, HR 1.802, 95% CI 1.205–2.695, P = 0.004), and multiple tumors (HR 1.676, 95% CI 1.075–2.615, P = 0.023) were associated with postoperative recurrence, whereas MVI (HR 2.737, 95% CI 1.475–5.080, P = 0.001), postoperative worsening of ALBI grade (HR 2.268, 95% CI 1.227–4.189, P = 0.009), high alpha-fetoprotein level (HR 2.055, 95% CI 1.136–3.716, P = 0.017), and transfusion (HR 2.597, 95% CI 1.395–4.834, P = 0.003) negatively influenced long-term survival. Patients with postoperative worsening of ALBI grade exhibited increased incidence of recurrence and worse long-term survival. Postoperative worsening of ALBI grade was associated with increased recurrence and poorer overall survival for patients with HBV-related HCC within the Milan criteria. We should pay attention to liver function changes in HCC patients after liver resection.

A total of 89 HCC patients enrolled in this study, 39 received preoperative TAC 1 week before surgery (pTAC group) and 50 did not (non-pTAC group). All patients underwent hepatectomy and postoperative TAC and were followed up to 400 weeks. Samples of liver tissue without HCC and hepatitis ( n = 15) served as normal controls. Cellular levels of 8-hydroxy-2′-deoxyguanosine (8-OHdG), TP53, and p21 waf1/cip1 were measured in both cancer and surrounding tissues using an immunohistochemistry assay. Taken together, our data suggested that preoperative TAC might postpone postoperative HCC relapse within 1 year via suppression of tumor cells by induction of high levels of oxidative stress.

Hepatocellular carcinoma (HCC) is one of the most common cancers worldwide (1), with an upward trend in most countries over the last 20 years. While surgical resection remains as the first-line therapy for HCC, the relevant high postoperative recurrence rate is still the major concern, responding for poor survival in most cases (2). The comparison between anatomic resection (AR) and non-anatomic partial resection (NAR) has been discussed for several decades, making it more clear of their application based on tumor features and underlying liver disease, but yet much needs to be completed.

Background Biliary reconstruction in ex vivo liver resection followed by autotransplantation (ERAT) for end-stage hepatic alveolar echinococcosis (HAE) remains the most challenging step, we present our experience with this complex procedure. Methods A retrospective data analysis of 55 patients with end-stage HAE underwent ERAT, the biliary reconstruction techniques and short- and long-term outcomes were discussed. Results All autografts were derived from the left lateral section after extensive ex vivo liver resection, multiple bile ducts were observed in 52 (94.5%) patients, and forty-four (80.0%) cases required ductoplasty. Biliary reconstruction was achieved with duct-to-duct anastomosis in 32 (58.2%) patients, Roux-en-Y hepaticojejunostomy (RYHJ) in 14 (25.5%) patients, and a combination of the two methods in 9 (16.4%) patients. Twenty (36.4%) patients had multiple anastomoses. Biliary leakage occurred in 8 (14.5%) patients postoperatively. Three (5.5%) patients died of liver failure, cerebral hemorrhage and intraabdominal bleeding. During a median of 31 months followed-up time, 3 (5.5%) patients developed anastomotic stricture, 1 of whom was treated by repeat RYHJ, while the others were managed with stenting. Conclusions With a well-designed plan and precise anastomosis, complex biliary reconstruction in ERAT can be performed with few biliary complications by a professional team.

Background Type 2 diabetes mellitus has been proved to be a risk factor of hepatocellular carcinoma, but how diabetes affects incidence of hepatocellular carcinoma among patients with chronic hepatitis B virus infection remains controversial. Methods A comprehensive search of Medline and Embase was performed. Incidence of hepatocellular carcinoma in chronic hepatitis B patients was the primary outcome. Pooled HRs and 95% CIs were calculated to assess the correlation between diabetes and incidence of hepatocellular carcinoma. Results Five cohort studies and two case-control studies were identified, with a total of 21,842 chronic hepatitis B patients. The diabetes mellitus cohort was found to have increased incidence of hepatocellular carcinoma (pooled HR 1.77, 95% CI 1.28-2.47; fixed effect) and worse overall mortality (pooled RR 1.93, 95% CI 1.64-2.27; fixed effect) in comparison with those without diabetes. In case-control studies, hepatocellular carcinoma cases were found to have an insignificantly elevated diabetes mellitus rate in comparison with the control group. Conclusion Type 2 diabetes mellitus is significantly associated with increased risk of hepatocellular carcinoma among patients with chronic hepatitis B virus infection, and aggressive management of diabetes mellitus is strongly suggested.

Aim To investigate the impact of circadian rhythms on the outcomes of liver transplantation on patients suffering from hepatocellular carcinoma (HCC). Methods We retrospectively reviewed data of patients who underwent liver transplantation from 2012 to 2017 in our center. Based on the begin time of transplantation, these patients were separated into 2 groups: day group and night group. The intraoperative and postoperative clinical variables were analyzed to find out the impact of the circadian rhythms. Multivariate analysis was performed to examine strength associations between the begin time of operation and surgical outcomes. Results A total of 147 patients were included in this study: 102 patients in the day group and 45 patients in the night group. Compared with the day group, patients in the night group had higher incidence of intraoperative massive hemorrhage (11.1% vs 2.0%, P = .048), more intraoperative blood loss (2168.00 ± 2324.20 mL vs 1405.88 ± 1037.69 mL, P = .040), and more requirement of red blood cells (RBC) suspension (8.59 ± 7.11 u vs 6.37 ± 5.78 u, P = .048). In addition, total operation time in the night group was longer than that in the day group (8.90 ± 1.65 hours vs 8.26 ± 1.69 hours, P = .034), as well as the cold ischemia time (9.35 ± 5.03 hours vs 7.21 ± 3.93 hours, P = .014). Furthermore, the night group had higher incidence of other intraoperative complications (13.3% vs 2.9%, P = .038), postoperative abdominal infection (20.0% vs 6.9%, P = .038), and more hospital cost (37,357.96 ± 6779.96 dollars vs 33,551.75 ± 11,683.38 dollars, P = .045). Moreover, patients in the night group needed longer time to restore hepatic function to normal (21.77 ± 10.91 days vs 17.54 ± 10.80 days, P = .033). Multivariate analysis showed that begin time of operation was the independent risk factor of longer operation time, more blood loss during operation, higher incidence of massive hemorrhage and other intraoperative complications, longer time for restoration of hepatic function to normal, higher incidence of abdominal infection at the early stage after transplantation, and more hospital cost (all P value ≤ .05). Conclusion Liver transplantation performed at night was associated with higher incidence of intraoperative and early postoperative complications, as well as higher hospital cost. And these worsened outcomes all could be explained by the influence that circadian rhythms had on patients or medical workers.

BACKGROUND Albumin-Bilirubin (ALBI) grade has been evaluated as an objective method to assess liver function and predict postoperative complications, particularly after hepatectomy in patients with hepatocellular carcinoma (HCC). However, ALBI grade was rarely used in evaluation in living donor liver transplantation (LDLT). MATERIAL AND METHODS Between March 2005 and November 2015, 272 consecutive patients undergoing right-lobe LDLT were enrolled in this study. According to the ALBI score used to evaluate recipients preoperatively, those patients were divided into 3 grades (I, II, and III). Demographic findings and the post-operative complication rates were collected and compared among groups. RESULTS The proportions of massive blood cell transfusions were different among those 3 grades (p

Objective To investigate the clinical effects of surgical intervention for end-stage hepatic alveolar echinococcosis (HAE). Methods We conducted a retrospectively study included 561 end-stage HAE patients between 2004 and 2016. The demographic characteristics, clinical data, and follow-up outcomes were collected and analysed. Kaplan-Meier curves were used for the overall survival (OS) and disease progression-free survival (PFS) analyses. COX multivariable regression analysis was carried out to identify risk factors. Result A total of 122 patients received surgical intervention were included, 55 cases underwent two-stage hepatectomy (group A, n=55), 21 cases underwent liver transplantation (group B, n=21), and 46 cases underwent non-radical reduction hepatectomy (groupC, n=46). The perioperative morbidity and mortality of liver transplantation group were significantly higher than other groups (47.6% and 14.3%). In group A, the 5- and 10-year OS rates were both 94.12%, and the 5- and 10-year PFS rates were both 91.18%. In group B, the 5- and 10-year OS rates were both 94.44%, and the 5- and 10-year PFS rates were both 94.44%. In group C, the 5- and 10-year OS rates were both 74.05%, and the 5- and 10-year PFS rates were both 54.58%. The rate of favorable prognosis in radical surgical treatment groups were much better than that in non-radical resection group ( P 0.001). Multivariate analysis indicated that diaphragm invasion ( P =0.021), neighbouring organs invasion ( P =0.027) and radical surgical treatment ( P =0.003) were the independent risk factors for OS. Multiple hepatic lobes invasion ( P =0.019), hepatic portal invasion ( P P =0.010) and radical surgical treatment ( P Conclusion Surgical intervention is effective and feasible for end-stage HAE. Patients received the radical operation treatment have better prognosis than those underwent palliative reduction resection.

Background There is currently limited information regarding the prognostic ability of the dNLR-PNI (the combination of the derived neutrophil-to-lymphocyte ratio [dNLR] and prognostic nutritional index [PNI]) for hepatocellular carcinoma (HCC). This study aimed to assess the predictive ability of the dNLR-PNI in patients with intermediate-to-advanced HCC after transarterial chemoembolization (TACE). Methods A total of 761 HCC patients were enrolled in the study. The dNLR-PNI was retrospectively calculated in these patients, as follows: patients with both an elevated dNLR and a decreased PNI, as determined using the cutoffs obtained from receiver operating characteristic curve analysis, were allocated a score of 2, while patients showing one or neither of these alterations were allocated a score of 1 or 0, respectively. Results During the follow-up period, 562 patients died. Multivariate analysis suggested that elevated total bilirubin, Barcelona Clinic Liver Cancer C stage, repeated TACE, and dNLR-PNI were independently associated with unsatisfactory overall survival. The median survival times of patients with a dNLR-PNI of 0, 1, and 2 were 31.0 (95% confidence interval [CI] 22.5–39.5), 16.0 (95% CI 12.2–19.7) and 6.0 (95% CI 4.8–7.2) months, respectively (P

Hepatocellular carcinoma (HCC) in adolescent and younger adult (AYA) patients is usually diagnosed at an advanced stage such that curative treatments are often not possible. The aimed of this study was to compare the outcome of attempted curative treatment, liver resection (LR) versus transarterial chemoembolization (TACE), in AYA patients presenting with intermediate or advanced HCC defined by the Barcelona Clinic Liver Cancer (BCLC) stage B and C.All AYA patients diagnosed with BCLC stage B or C HCC undertaking LR (n = 276) and TACE (n = 136) were included in our study. The prognostic factors of the patients were analyzed and the propensity score-matched patients (120 pairs) were analyzed to adjust for any baseline differences.The overall survival rate of the patients undertaking LR was higher than TACE for the both entire and the propensity matched population (p 0.001). In the multivariate analysis, propensity scoring analyses suggested that HBsAg positivity, macrovascular invasion, tumor size and TACE treatment were the independent prognostic factors associated with a worse survival outcome.The effect of LR was superior to that of TACE for patients with intermediate and advanced stage HCC. The survival outcome was associated with the tumor size, macrovascular invasion, and hepatitis history in AYA HCC patients.

The adoption of laparoscopic techniques for living donor major hepatectomy has been controversial issue. The aim of this study is to present the preliminary experience of laparoscopic right hepatectomy in China. All the donors receiving right hepatectomy for adult-to-adult living donor liver transplantation (LDLT) were divided into three groups: pure laparoscopic right hepatectomy (PLRH) group, hand-assisted right hepatectomy (HARH) group and open right hepatectomy (ORH) group. We compared the perioperative data and surgical outcomes of donors and recipients among three groups. From November 2001 to May 2017, 295 donors have received right hepatectomy for LDLT in our center. Among them, 7 donors received PLRH, 26 donors received HARH and 262 donors received ORH. The operation time of PLRH group (509.3 ± 98.9 min) was longer than that of the HARH group (451.6 ± 89.7 min) and the ORH group (418.4 ± 81.1 min, p = 0.003). The blood loss was the least in the PLRH group (378.6 ± 177.1 mL), compared with that in the HARH group (617.3 ± 240.4 mL) and that in the ORH group (798.6 ± 483.7 mL, p = 0.0013). The postoperative hospital stay was shorter in the PLRH group (7, 7–10 days) than that in the HATH group (8.5, 7.5–12 days) and ORH group (11, 9–14 days; p = 0.001). Only one donor had pleural effusion (Grade I) and another one experienced pulmonary infection (Grade II). One recipient (14.3%) in the PLRH group occurred hepatic venous stenosis. Laparoscopic approaches for right hepatectomy contribute to less blood loss, better cosmetic satisfaction, less severe complications, and faster rehabilitation. PLRH is a safe and feasible procedure, which must be performed in highly specialized centers with expertise of both LDLT and laparoscopic hepatectomy, and requires a hybrid-to-pure stepwise development.

Ex vivo liver resection combined with autotransplantation is a recently introduced approach to cure end‐stage hepatic alveolar echinococcosis (HAE), which is considered unresectable by conventional radical resection due to echinococcal dissemination into the crucial intrahepatic conduits and adjacent structures. This article aims discuss the manipulation details and propose reasonable indications for this promising technique. All patients successfully underwent liver autotransplantation with no intraoperative mortality. The median weight of the autografts was 636 g (360‐1300 g), the median operation time was 12.5 hours (9.4‐19.5 hours), and the median anhepatic phase was 309 minutes (180‐ 460 minutes). Intraoperative blood loss averaged 1800 mL (1200‐6000 mL). Postoperative complications occurred in 13 patients during hospitalization; 5 patients experienced postoperative complications classified as Clavien‐Dindo grade III or higher, and 2 patients died of intraabdominal bleeding and acute cerebral hemorrhage, respectively. Twenty‐nine patients were followed for a median of 14.0 months (3‐42 months), and no HAE recurrence was detected. The technique requires neither an organ donor nor any postoperative immunosuppressant, and the success of the treatment relies on meticulous preoperative assessments and precise surgical manipulation., This article discusses the details of ex vivo liver resection and autotransplantation in the treatment of end‐stage hepatic alveolar echinococcosis, including the feasibility, indications, preparation, technical innovations, and postoperative outcomes.

There is little information concerning futile liver resection for patients with Barcelona Clinic Liver Cancer (BCLC) stage B/C hepatocellular carcinoma (HCC). This study aimed to establish a predictive model of futile liver resection for patients with BCLC stage B/C HCC. The outcomes of 484 patients with BCLC stage B/C HCC who underwent liver resection at our centre between 2010 and 2016 were reviewed. Patients were randomised and divided 2:1 into training and validation sets. A novel risk-scoring model and prognostic nomogram were developed based on the results of multivariate analysis. Fifty-seven futile operations were observed. Multivariate analyses revealed tumour numbers > 3, Vp4 portal vein tumour thrombosis (PVTT) and alpha-fetoprotein (AFP) > 400 ng/ml independently associated with futile liver resection. A risk-scoring model based on the above-mentioned factors was developed (predictive risk score = 1 × (if AFP > 400 ng/ml) + 2 × (if tumour number > 3) + 3 × (if with Vp4 PVTT)). The area under the receiver-operating characteristic curve of this model was 0.845, with a sensitivity of 60.0% and a specificity of 94.8%. A prognostic nomogram was also developed and achieved a C-index of 0.831. The validation studies optically supported these results. A risk-scoring model and predictive nomogram for futile liver resection were developed in the present study. T`he BCLC stage B/C HCC patients with a high risk obtained no benefit from liver resection.

To investigate the association between tacrolimus (TAC) blood concentration and the risk of post-transplantation diabetes mellitus (PTDM) development after living donor liver transplantation (LDLT).This study reviewed the clinical data of 158 adult LDLT recipients. A cut-off of mean trough concentration of TAC (cTAC) value at the sixth month postoperatively was identified using a receptor operating characteristic curve. Other clinical complications rates were compared between different cTAC groups.Thirty-four (21.5%) recipients developed PTDM during follow-up period. Recipients with PTDM suffered lower 1-, 5- and 10-year overall survival rates (85.2%, 64.9%, and 55.6% vs 92.4%, 81.4%, and 79.1%, p 0.05) and allograft survival rates (87.9%, 76.9%, and 65.9% vs 94.1%, 88.5%, and 86.0%, p 0.05) than those without PTDM. The best cut-off value of mean cTAC was 5.9 ng/mL. Recipients with higher cTAC (5.9 ng/mL) were more likely to develop hyperlipidemia (39.6% vs 21.9%, p 0.05), cardio-cerebral events (7.5% vs1.0%, p 0.05), and infections (37.7% vs19.0%, p 0.05) than recipients exposed to low cTAC (≤5.9 ng/mL). However, the two groups showed no difference in the incidence of acute and chronic rejection.Higher mean cTAC at the sixth month postoperatively is related to increased risk of PTDM in LDLT recipients.

The potential prognostic value of stem cell markers is variably reported, such as CD133 and epithelial cell adhesion molecule. However, their clinical value and significance in hepatocellular carcinoma (HCC) remain controversial. The aim of this study was to carry out a meta-analysis of literature evaluating CD133 and epithelial cell adhesion molecule expression as prognostic factors in HCC and to determine the association between cancer stem cells (CSCs) and common clinical and pathologic features of HCC. The relevant literature was identified using Science Direct, EMBASE, and PubMed. Outcome measures included disease-free survival, overall survival, and relevant pathological parameters. Meta-analyses were carried out using Review Manager, version 5.2. Twelve eligible articles involving 1344 patients were included. Meta-analyses showed that the presence of CSCs was significantly associated with a poor histological grade (OR=3.16, P=0.003) and elevated serum α-fetoprotein level (OR=2.68, P

Chronic liver allograft dysfunction (CLAD) remains the most common cause of patient morbidity and allograft loss in liver transplant patients. However, the pathogenesis of CLAD has not been completely elucidated. By establishing rat CLAD models, in this study, we identified the informative CLAD-associated genes using isobaric tags for relative and absolute quantification (iTRAQ) proteomics analysis and validated these results in recipient rat liver allografts. CXCL4, CXCR3, EGFR, JAK2, STAT3, and Collagen IV were associated with CLAD pathogenesis. We validated that CXCL4 is upstream of these informative genes in the isolated hepatic stellate cells (HSC). Blocking CXCL4 protects against CLAD by reducing liver fibrosis. Therefore, our results indicated that therapeutic approaches that neutralize CXCL4, a newly identified target of fibrosis, may represent a novel strategy for preventing and treating CLAD after liver transplantation.

Here, we report a case of severe immune thrombocytopenia that occurred after orthotopic liver transplant. On day 16 after transplant, the patient was readmitted to our hospital with a platelet count of 0 cells/mL, with the count remaining at a low level of 1000 to 10 000 cells/mL for 46 days. A diagnosis was made, after exclusion of other causes, of thrombocytopenia. Platelet blood transfusion and high-dose prednisone (1mg/kg/d) combined with intravenous immunoglobulin (0.5g/kg/d) were administered with no improvement. After additional treatments, which included altered use of immunosuppressive agents, changing adefovir to lamivudine and continuous steroid therapy, the patient was discharged with a platelet count of 55 000 cells/mL. Both liver and renal functions generally stayed well during hospitalization. The patient was discharged uneventfully and achieved remission during 10-month follow-up after discharge.

The balanced application of a model for the estimate of outcomes of liver transplantation, in concert with assessment of disease severity, would not only improve transplant outcomes and maximize patient benefit from transplantation, but also facilitate informed decision making by patients and their relatives when considering transplantation. So far, however, linear discriminating methods have failed to attain sufficient power to predict post-transplant prognosis. Therefore, our aim was to develop a cancer-specific prognostic model by a nonlinear methodology based on pretransplant characteristics.With data collected retrospectively from 290 liver transplant recipients with HCC from February 1999 to August 2009, a multilayer perceptron (MLP) neural network was constructed to predict mortality risk after transplantation. Its predictive performances at posttransplant 1-, 2-, and 5-year intervals were evaluated using a receiver operating characteristic curve.By the forward stepwise selection in MLP network, donor age, donor body mass index, recipient hemoglobin, serum concentrations of total bilirubin, alkaline phosphatase, creatinine, aspartate aminotransferase, international normalized ratio of prothrombin time, and Na(+); alpha fetoprotein categorization, total diameter, number of tumor lesions, presence of imaging macrovascular invasion, and lobe distribution of the tumor were identified to be the optimal input features. The MLP, employing 24 inputs and 7 hidden neurons, yielded c-statistics of 0.909 (P.001) in the 1-year, 0.888 (P.001), in the 2-year, and 0.845 (P.001) in the 5-year prediction.Post-transplant prognosis is a multidimensional, nonlinear problem, and the specific MLP can achieve high accuracy in the prediction of posttransplant mortality risk for HCC recipients. The pattern recognition methodologies like MLP hold promise for solving outcome prediction after liver transplantation.

Ex vivo liver resection and autotransplantation (ELRA) was first introduced by Pichlmayr R (Klinik fur Abdominal- und Transplantationschirurgie, Medizinischen Hochschule, Hannover, FRG) [1]. The procedure was performed in February 1988 in a 46-year-old patient to remove large metastases from a leiomyosarcoma of the stomach. Subsequently, Hannoun et al. [2] and Sauvanet et al. [3] developed a simplified technique of “ex situ” hepatic surgery, in which wide access to all parts of the liver is provided by sectioning the infrahepatic and suprahepatic vena cava, while preserving the continuity of the portal triad.

The association between aflatoxin B1 (AFB1) exposure and oxidative stress was extensively examined in 84 adolescents from an area at high risk for hepatocellular carcinoma in China. Plasma level of aflatoxin B1-albumin adducts (AAAs) was associated with AFB1 excretion in urine (r = 0.394, P0.001). Urinary AFB1 was also associated with both the urinary excretion of 8-hydroxydeoxyguanosine (8-OHdG) (ror = 0.479, P0.001) and 8-OHdG and hOGG1 levels in peripheral leukocytes (ror = 0.308, Por = 0.005). Similarly, AAA was significantly associated with both the urinary excretion of 8-OHdG (ror = 0.259, Por = 0.018) and the 8-OHdG and hOGG1 levels in peripheral leukocytes (ror = 0.313, Por = 0.004). In addition, urinary 8-OHdG was correlated with both the level of DNA 8-OHdG (ror = 0.24, Por = 0.05) and the expression of hOGG1 in peripheral leukocytes (ror = 0.429, P0.001). Protein carbonyl content (PCC) level was significantly associated with not only the level of DNA 8-OHdG (ror = 0.366, P0.001) and the urinary 8-OHdG (ror = 0.258, Por = 0.018) but also the expression of hOGG1 in peripheral leukocytes (r = 0.485, P0.001). A significant but weak association was found between high-performance liquid chromatograph-electrochemical detection (HPLC-ECD) and enzyme-linked immunosorbent assay (ELISA) for urinary 8-OHdG (r = 0.334, P = 0.002) and between HPLC-ECD and flow cytometry assays for 8-OHdG in leucocytes (r = 0.395, P0.001). Significant associations were observed between AAA and PCC and liver function indices (alanine aminotransferase and aspartate aminotransferase). These findings suggest significant contribution from AFB1 exposure to oxidative stress and subsequent repair among adolescents that may impose substantial risk for hepatocarcinogenesis in adulthood in this region.

To determine the force mechanism for the steel plate shear wall with slits, the pushover analysis method was used in this study. An estimated equation for the lateral bearing capacity which considered the effect of edge stiffener was proposed. A simplified elastic-plastic analytical model for the stiffened steel slit wall composed of beam elements was presented, where the effects of edge stiffeners were taken into account. The wall-frame analysis model was established, and the geometric parameters were defined. Pushover analysis of two specimens was carried out, and the analysis was validated by comparing the results from the experiment, the shell element model, and a simplified model. The simplified model provided a good prediction of the lateral stiffness and the strength of the steel slit wall, with less than 10% error compared with the experimental results. The mutual effects of the bearing wall and the frame were also predicted correctly. In the end, the seismic performance evaluation of a steel slit wall-frame structure was presented. The results showed that the steel slit wall could prevent the beams and columns from being damaged by an earthquake and that the steel slit wall was an efficient energy dissipation component.

We sought to identify the risk factors associated with the early mortality after a living-donor liver transplant.Two hundred eighteen patients were recruited in this study. Potential risk factors were analyzed using univariate and multivariate analyses. A C statistic equivalent to the area under the receiver operating characteristic curve was used to assess the ability of the model to predict mortality risk during the first 3 months after a living-donor liver transplant.Twenty-six recipients died within the first 3 months after a living-donor liver transplant. On a multivariate analysis, intraoperative allogeneic red blood cell transfusion and the preoperative creatinine levels were independently associated with early postoperative mortality. A prognostic model was proposed in this study (early mortality risk score = 0.107 × intraoperative allogeneic red blood cells transfusion [U] + 0.005 × preoperative creatinine concentration [μmol/L]). Three-month survival rates of patients with high and low scores were 69.8% and 95.5% (P.001).Transfusion of intraoperative allogeneic red blood cell and preoperative creatinine levels are associated with the early mortality after living-donor liver transplant. A model to predict early mortality after a living-donor liver transplant based on these risk factors was proposed in this study.

Chronic liver allograft dysfunction is the leading cause of patient morbidity and late allograft loss after liver transplantation. The pathogenesis of chronic liver allograft dysfunction remains unknown. Recent studies have demonstrated that CXCL4 and its variant CXCL4L1 are involved in organ damage induced through inflammatory and immune responses throughout all stages of liver transplantation. CXCL4 and CXCL4L1 are low-molecular-weight proteins that have been implicated in hematopoiesis, angiostasis, organ fibrogenesis, mitogenesis, tumor growth and metastasis. The purpose of this review is to discuss the current status and future developments of research into the roles of CXCL4 and CXCL4L1 in the pathogenesis of chronic liver allograft dysfunction. The potential utilization of CXCL4 and CXCL4L1 as therapeutic targets for chronic liver allograft dysfunction will also be discussed.

The purpose of this study was to identify the incidence, outcomes, and risk factors of postoperative abdominal bleeding after living-donor liver transplant.Adult patients who had living-donor liver transplant between 2001 and 2013 were evaluated. Preoperative and intraoperative variables of transplant recipients were analyzed retrospectively with univariate analysis. Cox proportional hazards regression model was used to identify independent factors for postoperative bleeding.There were 241 living-donor liver transplant recipients included in the study. Postoperative abdominal bleeding was observed in 12 recipients (5%). The 3-month cumulative survival was significantly lower in recipients who had postoperative bleeding (survival, 8 patients [67%]) than recipients who did not have postoperative bleeding (survival, 204 patients [89%]; P = .009). Univariate analysis showed that preoperative albumin level, Child-Pugh class, and intraoperative blood loss were risk factors for postoperative bleeding. In multivariate analysis, intraoperative blood loss and Child-Pugh status were significant risk factors for postoperative bleeding.Living-donor liver transplant recipients who had postoperative bleeding had a poor outcome. Postoperative bleeding was associated with higher intraoperative blood loss and Child-Pugh class.

To detect whether the up-to-seven should be used as inclusion criteria for liver transplantation for hepatocellular carcinoma.Between April 2002 and July 2008, 220 hepatocellular carcinoma (HCC) patients who were diagnosed with HCC and underwent liver transplantation (LT) at our liver transplantation center were included. These patients were divided into three groups according to the characteristics of their tumors (tumor diameter, tumor number): the Milan criteria group (Group 1), the in up-to-seven group (Group 2) and the out up-to-seven group (Group 3). Then, we compared long-term survival and tumor recurrence of these three groups.The baseline characteristics of transplant recipients were comparable among these three groups, except for the type of liver graft (deceased donor liver transplant or live donor liver transplantation). There were also no significant differences in the pre-operative α-fetoprotein level. The 1-, 3-, and 5-year overall survival and tumor-free survival rate for the Milan criteria group were 94.8%, 91.4%, 89.7% and 91.4%, 86.2%, and 86.2% respectively; in the up-to-seven criteria group, these rates were 87.8%, 77.8%, and 76.6% and 85.6%, 75.6%, and 75.6% respectively (P0.05). However, the advanced HCC patients' (in the group out of up-to-seven criteria) overall and tumor-free survival rates were much lower, at 75%, 53.3%, and 50% and 65.8%, 42.5%, and 41.7%, respectively (P0.01).Considering that patients in the up-to-seven criteria group exhibited a considerable but lower survival rate compared with the Milan criteria group, the up-to-seven criteria should be used carefully and selectively.

AIM: To validate the “Metroticket” predictor using a large cohort of liver transplantation (LT) patients with hepatocellular carcinoma (HCC) in China. METHODS: In total, 230 cases of LT for HCC treatment at our center, from July 2000 to August 2008, were included in the present study. The predicted 1-, 3- and 5-year post-LT survival rates were calculated using the Metroticket model (http://89.96.76.14/metroticket/calculator/). The predicted and observed long-term survival rates were then compared and analyzed. RESULTS: The predicted survival rates for all 230 cases, as calculated by the Metroticket model, were 64.7% and 56.2% at 3 and 5 years, respectively, and the observed survival rates for these patients were 71.3% and 57.8%, respectively. For the 23 cases with macrovascular invasion, the predicted 5-year survival rate was 43.5%, whereas the observed 5-year survival rate was only 8.7%. For the 42 cases with microvascular invasion but an absence of macrovascular invasion, the predicted 5-year survival rate was 44.9%, and the observed 5-year survival rate was 50%. For the remaining 165 patients without any vascular invasion, the predicted 5-year survival rate was 65.8%, and the observed 5-year survival rate was 66.7%. CONCLUSION: The Metroticket model can be used to accurately predict survival in HCC-related LT cases with an absence of macrovascular invasion.

Some patients with portal hypertension due to hepatitis B cirrhosis who were suitable for periesophagogastric devascularization with splenectomy (PDS) also met the indications of liver transplantation (LT), the study compared the effect of PDS and LT, and of PDS followed by LT when required.Patients with portal hypertension due to hepatitis B cirrhosis were analyzed. Patients were organized into PDS or LT groups, and PDS followed by LT.The PDS group suffered from lower incidence of severe postoperative complications (p=0.007) and perioperative death (p=0.015) than group LT. The 1-, 3- and 5-year survival rates of the PDS and LT groups were 99.3%, 98.1% and 89.0%, and 91.1%, 85.4% and 79.0%, respectively (p=0.04). There were no significant differences in severe postoperative complications (p=1.000) or perioperative mortality (p=1.000) between the PDS followed by LT and the LT groups, and their 1-, 3- and 5-year survival rates were 91.2%, 82.1% and 82.1%, and 91.1%, 85.4% and 79.0%, respectively (p=0.694).For patients with portal hypertension due to hepatitis B cirrhosis, when they satisfy the indications for both PDS and LT, we appeal to perform PDS as bridging therapy for final liver transplantation.
