This study verified whether radical treatment for hepatocellular carcinoma (HCC) oligo-recurrence after liver transplantation conveys survival benefits. A retrospective study of 144 patients with posttransplant HCC recurrence was performed. Propensity score matching was performed to adjust for baseline covariates between patients who received radical and palliative treatments. The primary endpoint was postrecurrence survival. A total of 50 patients (35%) received radical treatment for recurrence, and 76 (53%) and 18 (13%) patients received palliative and supportive treatments, respectively. Compared with the radical group, patients who received palliative treatment had more early recurrences (time from transplant 17 versus 11 months; P = 0.01) and more extensive disease in terms of tumor numbers (1 versus 4; P

BACKGROUND AND AIMS There are no prospective data on stereotactic body radiation therapy (SBRT) as a bridge to liver transplantation for HCC. This study aimed to evaluate the efficacy and safety of SBRT as bridging therapy, with comparison with transarterial chemoembolization (TACE) and high-intensity focused ultrasound (HIFU). APPROACH AND RESULTS Patients were prospectively enrolled for SBRT under a standardized protocol from July 2015 and compared with a retrospective cohort of patients who underwent TACE or HIFU from 2010. The primary endpoint was tumor control rate at 1 year after bridging therapy. Secondary endpoints included cumulative incidence of dropout, toxicity, and posttransplant survival. During the study period, 150 patients were evaluated (SBRT, n = 40; TACE, n = 59; HIFU, n = 51). The tumor control rate at 1 year was significantly higher after SBRT compared with TACE and HIFU (92.3%, 43.5%, and 33.3%, respectively; P = 0.02). With competing risk analysis, the cumulative incidence of dropout at 1 and 3 years after listing was lower after SBRT (15.1% and 23.3%) compared with TACE (28.9% and 45.8%; P = 0.034) and HIFU (33.3% and 45.1%; P = 0.032). Time-to-progression at 1 and 3 years was also superior after SBRT (10.8%, 18.5% in SBRT, 45%, 54.9% in TACE, and 47.6%, 62.8% in HIFU; P

In spite of early adoption of the brain death legislation, and all efforts at promoting deceased donation, various social, economic and cultural factors have acted as road blocks to the furthering of deceased donor liver transplantation (DDLT) in most Asian societies. On the other hand, Asian liver transplant centers have been the pioneers, innovators, and technical advancement catalysts for the world to follow, especially with regards to living donor liver transplantation (LDLT). With some high volume centers performing more than 200 LDLTs a year with good outcomes in the donor and recipient, techniques to expand the living donor pool have also been adopted like ABO-incompatible, paired exchange and dual lobe living donor liver transplants. Although large multicenter, and registry data as regards safety and outcomes of minimally invasive donor hepatectomy are awaited, expert centers have pioneered, and now regularly perform purely laparoscopic and robotic living donor hepatectomies, especially in Korea.

Gallbladder cancer (GBCA) is a rare and fatal disease and the majority of patients presents with advanced stage. Surgical resection associated with lymphadenectomy is the only chance for cure. For patients in stages III and IV, extended resection is the only treatment to achieve R0 margins. For GBCA invading the hepatoduodenal ligament and pancreatoduodenal region, the resection of extrahepatic bile duct and pancreas is necessary. Hepatopancreatoduodenectomy (HPD) represents the most complex and challenging procedure in the hepatopancreatobiliary region. Kuno at the Cancer Institute Hospital Tokyo performed the first HPD in Japan in 1974 and in 1980 Takasaki presented five cases and the 30-day mortality was 60%. After that, other countries started to perform the procedure including United States and Brazil. The main complications are liver failure and pancreatic fistula. Advancements in perioperative care, surgical technique, medical instruments and postoperative at intensive care unit have resulted in reduction in morbidity and mortality. The use of portal vein embolization is indicated to increase the liver volume in patients with insufficient remnant. Preoperative biliary drainage can prevent cholangitis and improve hepatic function. This procedure should be recommended before extended HPD in jaundiced patients. Operative results with mortality rates below 5% at high volume centers suggest that HPD should be performed at centers with expertise in hepatopancreatobiliary surgery.

OBJECTIVE To study the impact of LT experience on the outcome of CLR for locally advanced hepatobiliary malignancy SUMMARY OF BACKGROUND DATA:: Despite evolution in LT knowledge and surgical techniques in the past decades, there is yet data to evaluate the significance of LT experience in performing CLR. METHODS Postoperative outcome after CLR between 1995 and 2019 were reviewed and correlated with LT experience in a single center with both LT and CLR service. CLR was defined as hepatectomy with vasculobiliary reconstruction, or multivisceral resection, central bisectionectomy (S4/5/8), or associating liver partition and portal vein ligation for staged hepatectomy. Spearman rank correlation and receiver operating characteristic analysis were used to define the association between CLR-related outcomes and LT experience. RESULTS With cumulative single-center experience of 1452 LT, 222 CLR were performed during the study period [hepatectomy with biliary (27.0%), or vascular (21.2%) reconstruction, with multivisceral resections (9.9%), with associating liver partition and portal vein ligation for staged hepatectomy (18.5%)] mainly for hepatocellular carcinoma (53.2%), and hilar cholangiocarcinoma (14%). Median tumor size was 7.0 cm. Other features include macrovascular invasion (23.4%), and juxta-visceral invasion (14%). Major postoperative complication rate was 25.2% and mortality rate was 6.3%. CLR-complication rate was inversely associated with LT experience (R = -0.88, P < 0.005). Receiver operator characteristic analysis revealed the cutoff for LT experience to have the greatest influence on CLR was 95 with a sensitivity of 100% and Youden index of 1. Multivariable analysis showed that blood transfusion, prolonged operating time, LT experience

The 25th Annual Congress of the International Liver Transplantation Society was held in Toronto, Canada, from May 15 to 18, 2019. Surgeons, hepatologists, anesthesiologists, critical care intensivists, radiologists, pathologists, and research scientists from all over the world came together with the common aim of improving care and outcomes for liver transplant recipients and living donors. Some of the featured topics at this year's conference included multidisciplinary perioperative care in liver transplantation, worldwide approaches to organ allocation, donor steatosis, and updates in pediatrics, immunology, and radiology. This report presents excerpts and highlights from invited lectures and select abstracts, reviewed and compiled by the Vanguard Committee of International Liver Transplantation Society. This will hopefully contribute to further advances in clinical practice and research in liver transplantation.

Purpose of review Application of living donor liver transplantation (LDLT) in model for end-stage liver disease (MELD) 35+ patients has been regarded with skepticism. There is concern that a partial graft may not achieve favourable outcomes, and that a healthy donor is risked for a transplant which might turn out to be futile. Recent findings In practice, LDLT improves access to liver graft and allows timely transplantation. Long-term results from high-volume centres revealed that outcomes of LDLT in these patients have not been jeopardized by limited graft volumes. With unimpeded vascular outflow, a partial graft could provide sufficient function to overcome the stress of transplant operation. However, LDLT is a complex operation with immense technical demand. A steep learning curve is encountered before optimal outcomes could be produced. Meanwhile, donor safety remains the paramount concern. Donor should not be evaluated for futile candidates. MELD 35+ patients with refractory sepsis or cardiac event are unlikely to benefit from liver transplantation. Borderline donors, in terms of donor safety or graft quality, should not be accepted. As in recipient operation, accumulation of experience is crucial to reduce donor mortality and morbidity. Summary LDLT is justified for MELD 35+ in high-volume centres with vast experience. Satisfactory recipient outcomes can be produced with minimal donor morbidity.

Most management guidelines and much of the available clinical trial evidence for immunosuppressants in liver transplantation (LT) pertain to Western practice. While evidence from Western studies may not translate to Asian settings, there is a paucity of Asian randomized controlled trials of immunosuppression in liver recipients. Nonetheless, there are notable differences in the indications and procedures for LT between Western and Asian settings. The Asian Liver Transplant Network held its inaugural meeting in Singapore in November 2016 and aimed to provide an Asian perspective on aspects of immunosuppression following LT. Because of their importance to outcome following LT, the meeting focused on (1) reducing the impact of renal toxicity, (2) hepatocellular carcinoma recurrence, and (3) nonadherence with immunosuppressant therapy.

Objective: Associating Liver Partition and Portal vein ligation for Staged hepatectomy (ALPPS) has been tested in various indications and clinical scenarios, leading to steady improvements in safety. This report presents the current status of ALPPS. Summary Background Data: ALPPS offers improved resectability, but drawbacks are regularly pointed out regarding safety and oncologic benefits. Methods: During the 12th biennial congress of the European African-Hepato-Pancreato-Biliary Association (Mainz, Germany, May 23-26, 2017) an expert meeting "10th anniversary of ALPP" was held to discuss indications, management, mechanisms of regeneration, as well as pitfalls of this novel technique. The aim of the meeting was to make an inventory of what has been achieved and what remains unclear in ALPPS. Results: Precise knowledge of liver anatomy and its variations is paramount for success in ALPPS. Technical modifications, mainly less invasive approaches like partial, mini- or laparoscopic ALPPS, mostly aiming at minimizing the extensiveness of the first-stage procedure, are associated with improved safety. In fibrotic/cirrhotic livers the degree of future liver remnant hypertrophy after ALPPS appears some less than that in noncirrhotic. Recent data from the only prospective randomized controlled trial confirmed significant higher resection rates in ALPPS with similar peri-operative morbidity and mortality rates compared with conventional 2-stage hepatectomy including portal vein embolization. ALPPS is effective reliably even after failure of portal vein embolization. Conclusions: Although ALPPS is now an established 2-stage hepatectomy additional data are warranted to further refine indication and technical aspects. Long-term oncological outcome results are needed to establish the place of ALPPS in patients with initially nonresectable liver tumors.

Salvage liver transplantation (sLT) and repeated resection (RR) are effective treatments for recurrent hepatocellular carcinoma (HCC), and comparisons of the oncological outcomes between these 2 modalities were scarce. Consecutive patients admitted for either sLT or RR for recurrent HCC were recruited. All patients in the present series received either prior hepatectomy, ablative therapy, or both before RR or sLT. Patient demographic, perioperative, and outcome data were analyzed. A survival analysis was performed after propensity score matching. There were 277 eligible patients recruited, and 67 and 210 of them underwent sLT and RR, respectively. Significant differences in preoperative hemoglobin, albumin, Model of End-Stage Liver Disease (MELD) score, and tumor number were found between the sLT and RR groups. After 1:3 propensity score matching, there were 36 sLT and 108 RR patients for comparison. The median age, MELD, alpha fetoprotein, and tumor size and number of the matched population were 57 years, 7.5, 16 ng/mL, 2.5 cm, and 1, respectively. There was no difference in the hospital mortality and complication rate (Clavien IIIa or above) between the groups. The recurrence rate after RR was significantly higher than for the patients who received sLT (72.2% versus 27.8%; P < 0.001). Following RR, 3 patients received liver transplantation for further recurrence, and 54.6% of the patients developed nontransplantable recurrence. The 5-year disease-free survival (DFS) and overall survival (OS) were both superior in the sLT group (DFS, 71.6% versus 32.8%, P < 0.001; OS, 72.8% versus 48.3%, P = 0.007). In conclusion, sLT is superior to RR for treatment of recurrent HCC in terms of DFS and OS. The high rate of nontransplantable recurrence after reresection underscores the importance of timely sLT.

The objective of this article is to derive a more accurate and easy-to-use formula for finding estimated standard liver volume (ESLV) using novel computed tomography (CT) measurement parameters. New formulas for ESLV have been emerging that aim to improve the accuracy of estimation. However, many of these formulas contain body surface area measurements and logarithms in the equations that lead to a more complicated calculation. In addition, substantial errors in ESLV using these old formulas have been shown. An improved version of the formula for ESLV is needed. This is a retrospective cohort of consecutive living donor liver transplantations from 2005 to 2016. Donors were randomly assigned to either the formula derivation or validation groups. Total liver volume (TLV) measured by CT was used as the reference for a linear regression analysis against various patient factors. The derived formula was compared with the existing formulas. There were 722 patients (197 from the derivation group, 164 from the validation group, and 361 from the recipient group) involved in the study. The donor's body weight (odds ratio [OR], 10.42; 95% confidence interval [CI], 7.25-13.60; P

There is presently no evidence-based recommendation for surveillance of recurrent hepatocellular carcinoma after liver transplantation (LT). We aim to evaluate and develop evidence-based alternate surveillance imaging schedules for post-LT hepatocellular carcinoma patients.Imaging and pathologic reports for consecutive post-LT patients followed up by regular surveillance imaging from a single institution's prospective database were evaluated with institutional review board approval. Outcome variable was time to diagnosis of first recurrence post-LT by surveillance imaging. Recurrence-free survival times from alternative surveillance schedules were compared with the existing schedule (every 3 months) using a parametric frailty model. Expected delay (EpD) in diagnosis compared to the existing schedule was also computed for the alternate surveillance schedules. A P value less than 0.05 was considered to indicate a significant difference.One hundred twenty-five patients (108 men; 59.4 ± 16.6 years) underwent 1953 computed tomography and 255 magnetic resonance imaging scans. Recurrence-free survival time was not significantly different in the first 5 years after LT when the imaging interval was extended from current every 3 months to every 6 months (P = 0.786, EpD = 55 days). This alternative schedule incurred 10 (50.0%) fewer surveillance scans than the 20 in the original schedule, and a corresponding reduction in radiation dose (if involved) and cost during the 5-year follow-up period.In conclusion, modeled alternative surveillance schedules have the potential to reduce the frequency of scans without compromising surveillance benefits.

To evaluate if living donor liver transplantation (LDLT) should be offered to patients with Model for End-stage Liver Disease (MELD) scores ≥35.No data was available to support LDLT of such patients.Data of 672 consecutive adult liver transplant recipients from 2005 to 2014 at our center were reviewed. Patients with MELD scores ≥35 were divided into the deceased donor liver transplantation (DDLT) group and the LDLT group and were compared. Univariate analysis was performed to identify risk factors affecting survival.The LDLT group (n = 54) had younger (33 yrs vs 50 yrs, P0.001) and lighter (56 Kg vs 65 Kg, P = 0.004) donors, lighter grafts (627.5 g vs 1252.5 g, P0.001), lower graft-weight-to-recipient-standard-liver-volume rates (51.28% vs 99.76%, P0.001), shorter cold ischemic time (106.5 min vs 389 min, P0.001), and longer operation time (681.5 min vs 534 min, P0.001). The groups were comparable in postoperative complication, hospital mortality, and graft survival and patient survival at one year (88.9% vs 92.5%; 88.9% vs 94.7%), three years (87.0% vs 86.9%; 87.0% vs 88.8%), and five years (84.8% vs 81.8%; 84.8% vs 83.3%). Univariate analysis did not show inferior survival in LDLT recipients.At centers with experience, the outcomes of LDLT can be comparable with those of DDLT even in patients with MELD scores ≥35. When donor risks and recipient benefits are fully considered and balanced, an MELD score ≥35 should not be a contraindication to LDLT. In Hong Kong, where most waitlisted patients have acute-on-chronic liver failure from hepatitis B, LDLT is a wise alternative to DDLT.

Purpose of review This article provides an update on the latest development on deploying oral nucleosides in an immunoglobulin-free regime against hepatitis B virus (HBV) recurrence after liver transplantation. Recent findings Entecavir and tenofovir are the two newer oral nucleosides that are associated with a low virological rebound rate at less than 2% at 5 years. As a result, they have been applied as standalone treatment against HBV recurrence after liver transplantation without immunoglobulin. Recent evidence has shown that a hepatitis B surface antigen seroclearance rate of 86% and 91% after 1 and 2 years was achievable with entecavir monotherapy. Moreover, none of the patients had histological graft damage because of HBV recurrence and an overall survival over 80% at 7 years has been reported. Summary With newer and more potent oral nucleos(t)ide (NA) available, a hepatitis B immune globulin-free regimen after liver transplantation has become safe and feasible for suppression of HBV recurrence after liver transplantation, and for avoidance of HBV-related graft complications.

The objective of this study was to investigate the outcomes of high-intensity focused ultrasound (HIFU) ablation as a bridging therapy for patients with hepatocellular carcinoma (HCC) who had been wait-listed for deceased donor liver transplantation (DDLT). Adult patients with unresectable and unablatable HCCs within the University of California San Francisco criteria who had been wait-listed for DDLT were screened for their suitability for HIFU ablation as a bridging therapy if they were not suitable for transarterial chemoembolization (TACE). Treatment outcomes for patients receiving HIFU ablation, TACE, and best medical treatment (BMT) were compared. Fifty-one patients were included in the analysis. Before the introduction of HIFU ablation, only 39.2% of the patients had received bridging therapy (TACE only, n = 20). With HIFU ablation in use, the rate increased dramatically to 80.4% (TACE + HIFU, n = 41). The overall dropout rate was 51% (n = 26). Patients in the BMT group had a significantly higher dropout rate (P = 0.03) and significantly poorer liver function as reflected by higher Model for End-Stage Liver Disease scores and higher Child-Pugh grading. Clinically relevant ascites was found in 5 patients in the HIFU group and 2 patients in the BMT group, but none was found in the TACE group (P = 0.01 and P = 0.03, respectively). The TACE and HIFU groups had comparable percentages of tumor necrosis in excised livers (P = 0.35), and both were significantly higher than that in the BMT group (P = 0.01 and P = 0.02, respectively). In conclusion, HIFU ablation was safe even for HCC patients with Child-Pugh C disease. Its adoption increased the percentage of patients receiving bridging therapy from 39.2% to 80.4%. A randomized controlled trial for further validation of its efficacy is warranted. Liver Transpl 20:912–921, 2014. © 2014 AASLD.

This aim of this study is to determine the risk factors in failed endoscopic retrograde cholangiography (ERC).Endoscopic treatment is considered the first-line intervention for biliary anastomotic stricture (BAS) after right-lobe living donor liver transplantation with duct-to-duct anastomosis.A retrospective study was performed on 287 patients who received right-lobe living donor liver transplantation with duct-to-duct anastomosis. The morphology of BAS was defined according to the shape of the distal side of duct-to-duct anastomosis shown on cholangiogram and was categorized into 3 types: pouched, intermediately pouched, and triangular. All cases of ERC were performed by operating surgeons.Fifty-nine patients (20.6%) had BAS and received ERC and balloon dilatation with or without stenting. The success rate was 73.2%. The median number of sessions needed for successful ERC was 3. In the 15 patients with failed ERC, 4 were successfully treated with percutaneous transhepatic biliary drainage and balloon dilatation and 11 underwent conversion hepaticojejunostomy (6 had external percutaneous transhepatic biliary drainage as a temporizing measure). On multivariate analysis, recipient age [odds ratio (OR): 0.922; 95% confidence interval (CI): 0.85-1.00; P = 0.049], operation time (OR: 1.007; 95% CI: 1.001-1.013; P = 0.025), and morphology of stricture (OR: 6.722; 95% CI: 1.31-34.48; P = 0.022) were independent risk factors associated with failed ERC. The success rates for the 3 types of BAS-pouched, intermediately pouched, and triangular-were 42.9%, 63.6%, and 88.9%, respectively (P = 0.021). Association was found between bile leak and pouched BAS (P = 0.008).ERC is highly effective in treating BAS. A success rate of 73%, the highest ever reported, has been achieved. Morphology of stricture is associated with outcome of ERC. Radiological or surgical intervention should be considered for patients with pouched BAS after endoscopic treatment fails for the first time.

To evaluate our preliminary experience of high-intensity focused ultrasound (HIFU) for the treatment of recurrent hepatocellular carcinoma (HCC).HIFU is a new thermal ablative therapy for HCC. Whether it incurs survival benefit similar to that of radiofrequency ablation (RFA) remains uncertain.Clinicopathological data of 27 patients who received HIFU ablation and 76 patients who received RFA for recurrent HCC from October 2006 to October 2009 were reviewed. Survival outcomes between the 2 groups were compared using the log-rank test. A value of P0.05 was considered significant.The median follow-up was 27.9 months. There was no difference in tumor size (HIFU, 1.7 cm; RFA, 1.8 cm; P = 0.28) between the 2 groups. Procedure-related morbidity rate was 7.4% in the HIFU group and 6.5% in the RFA group (P = 1.00). Skin burn and pleural effusion were the 2 morbidities associated with HIFU. There was no hospital mortality in the HIFU group, whereas 2 deaths occurred in the RFA group. The 1-, 2-, and 3-year disease-free survival rates were 37.0%, 25.9%, and 18.5%, respectively, for the HIFU group, and 48.6%, 32.1%, and 26.5%, respectively for the RFA group (P = 0.61). The 1-, 2-, and 3-year overall survival rates were 96.3%, 81.5%, and 69.8%, respectively, for the HIFU group, and 92.1%, 76.1%, and 64.2%, respectively, for the RFA group (P = 0.19).Our preliminary experience in using HIFU for recurrent HCC is promising. Further studies are needed to explore its treatment value for primary HCC.

The objective of this study was to evaluate the efficacy of salvage liver transplantation (SLT), repeated hepatic resection (RR), and repeated radiofrequency ablation (rRFA) for patients with postoperative tumor recurrence. The optimal treatment strategy for patients with recurrent hepatocellular carcinoma (HCC) remains unclear. From January 1993 to September 2009, 532 patients underwent either hepatic resection or radiofrequency ablation (RFA) for HCC within the Milan criteria. In all, 219 patients experienced intrahepatic recurrence, and 87 were selected for SLT (n=19), RR (n=24), or rRFA (n=44). Their clinicopathological data were reviewed, and their survival outcomes were assessed with Kaplan-Meier methods. Seventy-four of 220 patients (33.6%) developed recurrent HCC within the Milan criteria. The median Model for End-Stage Liver Disease (MELD) scores for SLT, RR, and rRFA were 10.7, 7.2, and 8.3, respectively (P

This study investigated the outcomes of living donor liver transplantation (LDLT) for patients with preoperative type 1 hepatorenal syndrome (HRS) and acute hepatic decompensation. Prospectively collected data for 104 patients who had fulminant hepatic failure, acute decompensation of cirrhosis, or an acute flare of chronic hepatitis B were analyzed. Thirty-three patients (31.7%) had HRS (the HRS group), and 71 patients (68.3%) did not (the non-HRS group). The median follow-up period was 60 months. The HRS group had significantly more preoperative intensive care unit (ICU) admissions (84.8% versus 60.6%, P = 0.01), worse preoperative blood test results (creatinine, 248 versus 88 μmol/L, P < 0.001; total bilirubin, 630 versus 555 μmol/L, P = 0.001), more hemodialysis (48.5% versus 0%, P < 0.001), more blood transfusions (9 versus 4 U, P < 0.001), longer postoperative ICU stays (8 versus 4 days, P < 0.001), worse postoperative blood test results (creatinine at 1 year, 108 versus 96 μmol/L, P = 0.006), and poorer overall survival (P < 0.001). In a multivariate analysis, only HRS was associated with poorer overall survival (hazard ratio = 8.592, 95% confidence interval = 1.782-41.431, P = 0.007). In conclusion, HRS patients had worse postoperative renal function and overall survival than non-HRS patients. However, their 5-year overall survival rate was still nearly 80%, which is satisfactory. Therefore, LDLT can be considered for patients who have acute hepatic decompensation with or without HRS. Liver Transpl, 2012. © 2012 AASLD.

Duct-to-duct anastomosis (DDA) and hepaticojejunostomy (HJ) are options for biliary reconstruction in patients undergoing adult-to-adult right lobe living donor liver transplantation (ARLDLT), after which biliary anastomotic stricture (BAS) is common as a complication. The risk factors for BAS are not clearly defined. We aimed to determine the rate of post-ARLDLT BAS in our center and its associated factors. In 265 ARLDLT recipients, 55 (20.8%) developed postoperative BAS. The diagnosis was based on clinical, biochemical, histological, and radiological results. The BAS rates were 21.4% (43/201) for recipients undergoing DDA during transplantation, 18.9% (10/53) for recipients undergoing HJ, and 18.2% (2/11) for recipients undergoing both procedures. BAS and non-BAS patients had comparable demographics. The number of graft bile duct openings (P = 0.516) and the size of the graft's smallest bile duct (5 versus 5 mm, P = 0.4) were not significantly different between BAS and non-BAS patients. Univariate analysis showed that the factors associated with postoperative BAS were the recipient warm ischemia time (55 versus 51 minutes, P = 0.026), graft cold ischemia time (120 versus 108 minutes, P = 0.046), stent use (21.8% versus 7.1%, P = 0.001), postoperative acute cellular rejection (29.1% versus 11.0%, P = 0.001), and University of Wisconsin solution use (21.8% versus 7.1%, P = 0.001). Multivariate analysis showed that the cold ischemia time (odds ratio = 1.012, 95% confidence interval = 1.002-1.023, P = 0.014) and acute rejection (odds ratio = 3.180, 95% confidence interval = 1.606-6.853, P = 0.002) were significant factors. The graft survival rates of BAS and non-BAS patients were comparable. One patient required retransplantation for secondary biliary cirrhosis. In conclusion, BAS remains common after ARLDLT regardless of DDA or HJ. The graft cold ischemia time and postoperative acute cellular rejection are significantly associated with postoperative BAS.

Curative resection remains the only hope of cure for hepatocellular carcinoma (HCC), but postoperative complications can have a significant impact on long-term survival. However, only scarce data on such impact can be found in the literature. This retrospective study reviewed the prospectively collected data of patients who underwent primary liver resection for HCC at our hospital during the period from December 1989 to December 2014. Patients with and without postoperative complications were compared. A 1:1 propensity score matching was adopted by matching age, comorbidity, Model of End-stage Liver Disease score, tumor stage, and extent of resection. Totally 1710 patients were eligible for the study. Four hundred and sixty-one (27.0%) of them developed postoperative complications while 1249 (73.0%) did not. After propensity score matching, 922 patients were compared in a 1:1 ratio (461 with postoperative complications and 461 without). Patients who developed postoperative complications were demographically similar to patients who did not, but had more intraoperative blood loss and transfusion (both P

Extremes of body mass index (BMI) at diagnosis of childhood cancers have been associated with poorer prognosis. The aims of this retrospective review were to examine the growth and BMI status of children diagnosed with neuroblastoma (NB) and determine if BMI status at diagnosis affected survival. Between 1985 and 2005, 154 children were diagnosed with NB at Sydney Children's Hospitals Network (Westmead), Australia, of which 129 had both length/height and weight recorded in the medical records at diagnosis. BMI was calculated and children were classified as underweight (BMI 85th percentile). Disease stage was classified according to the International NB Staging System. At diagnosis, 24.0% of the children were classified as underweight and 11.6% were overweight. Six months after diagnosis all children except those with stage 4s disease had a decrease in BMI z-score; difference in estimated marginal mean −0.73, P
