RESUMO
AIM: To study the incidence, risk factors and management of portal vein thrombosis (PVT) after hepatectomy for perihilar cholangiocarcinoma (PHCC). PATIENTS AND METHOD: Single-center retrospective analysis of 86 consecutive patients who underwent major hepatectomy for PHCC, between 2012 and 2019, with comparison of the characteristics of the groups with (PVT+) and without (PVT-) postoperative portal vein thrombosis. RESULTS: Seven patients (8%) presented with PVT diagnosed during the first postoperative week. Preoperative portal embolization had been performed in 71% of patients in the PVT+ group versus 34% in the PVT- group (P=0.1). Portal reconstruction was performed in 100% and 38% of PVT+ and PVT- patients, respectively (P=0.002). In view of the gravity of the clinical and/or biochemical picture, five (71%) patients underwent urgent re-operation with portal thrombectomy, one of whom died early (hemorrhagic shock after surgical treatment of PVT). Two patients had exclusively medical treatment. Complete recanalization of the portal vein was achieved in the short and medium term in the six survivors. After a mean follow-up of 21 months, there was no statistically significant difference in overall survival between the two groups. FINDINGS: Post-hepatectomy PVT for PHCC is a not-infrequent and potentially lethal event. Rapid management, adapted to the extension of the thrombus and the severity of the thrombosis (hepatic function, signs of portal hypertension) makes it possible to limit the impact on postoperative mortality. We did not identify any modifiable risk factor. However, when it is oncologically and anatomically feasible, left±extended hepatectomy (without portal embolization) may be less risky than extended right hepatectomy, and portal vein resection should only be performed if there is strong suspicion of tumor invasion.

BACKGROUND: Liver resection is a curative treatment for hepatocellular carcinoma (HCC) and an alternative to liver transplantation (LT). However, post-liver resection recurrence rates remain high. This study aimed to determine whether liver stiffness measurement (LSM) correlated with recurrence and to propose a method for predicting HCC recurrence exclusively using pre-liver resection criteria. METHODS: This retrospective monocentric study included patients who had undergone LR liver resection for HCC between 2015 and 2018 and who had (1) preoperative alpha-fetoprotein scores indicating initial transplant viability and (2) available preoperative LSM data. We developed a predictive score for recurrence over time using Cox univariate regression and multivariate analysis with a combination plot before selecting the optimal thresholds (receiver operating characteristic curves + Youden test). RESULTS: Sixty-six patients were included. After an average follow-up of 40 months, the recurrence rate was 45% (n = 30). Three-year overall survival was 88%. Four preoperative variables significantly impacted the time to recurrence: age ≥70 years, LSM ≥11 kPa, international normalized ratio (INR) ≥1.2, and maximum HCC diameter ≥3 cm. By assigning 1 point per positive item, patients with a score <2 (n = 22) demonstrated greater mean overall survival (69.7 vs 54.8 months, P = .02) and disease-free survival (52.2 vs 34.7 months, P = .02) than those with a score ≥2. Patients experiencing early recurrence (<1 year) presented a significantly higher preoperative LSM (P = .06). CONCLUSION: We identified a simple preoperative score predictive of early hepatocellular carcinoma recurrence after liver resection, highlighting the role of liver stiffness. This score could help physicians select patients and make decisions concerning perioperative medical treatment.

BACKGROUND: The influence of sex on primary sclerosing cholangitis (PSC), pre- and postliver transplantation (LT) is unclear. Aims are to assess whether there have been changes in incidence, profile, and outcome in LT-PSC patients in Europe with specific emphasis on sex. METHODS: Analysis of the European Liver Transplant Registry database (PSC patients registered before 2018), including baseline demographics, donor, biochemical, and clinical data at LT, immunosuppression, and outcome. RESULTS: European Liver Transplant Registry analysis (n = 6463, 32% female individuals) demonstrated an increasing number by cohort (1980-1989, n = 159; 1990-1999, n = 1282; 2000-2009, n = 2316; 2010-2017, n = 2549) representing on average 4% of all transplant indications. This increase was more pronounced in women (from 1.8% in the first cohort to 4.3% in the last cohort). Graft survival rate at 1, 5, 10, 15, 20, and 30 y was 83.6%, 70.8%, 57.7%, 44.9%, 30.8%, and 11.6%, respectively. Variables independently associated with worse survival were male sex, donor and recipient age, cholangiocarcinoma at LT, nondonation after brain death donor, and reduced size of the graft. These findings were confirmed using a more recent LT population closer to the current standard of care (LT after the y 2000). CONCLUSIONS: An increasing number of PSC patients, particularly women, are being transplanted in European countries with better graft outcomes in female recipients. Other variables impacting outcome include donor and recipient age, cholangiocarcinoma, nondonation after brain death donor, and reduced graft size.

Standardized discharge criteria are critical to reduce premature discharge and avoid unnecessary hospital stays. No such criteria exist for patients undergoing liver transplantation (LT). To achieve a consensus-based checklist of criteria for safe patient discharge after LT, this mixed-method study included the following: a systematic literature review and expert discussion to draft a first checklist of post-LT discharge criteria, defining patient recovery and indications for hospital discharge (functional recovery); an exploratory online electronic Delphi (e-Delphi) study; a single-center pilot study to test checklist feasibility; and a final e-Delphi study with an extended interdisciplinary expert panel to validate the final checklist. The first round provided a 10-point discharge checklist with 5 patient-centered items derived from discharge criteria after liver surgery and 5 graft-centered items derived from expert discussion. The restricted panel (9 experts) e-Delphi provided 100% consensus after the second round, with slight modifications to the criteria. During the pilot study, 19 of 45 (42.2%) patients included fulfilled the complete checklist (100% of 10 items) after median (IQR) 16 (8-21) days (functional recovery) and a length of stay of 20 (9-24) days. The item with the lowest completion rate was minimum serum tacrolimus level in the target on 2 consecutive blood samples (n = 21; 47%), achieved at 13 (9-15) days. The extended panel (66 experts) e-Delphi provided 95%-98% consensus after the third round, with slight modifications of the criteria. This study provided substantial consensus on discharge criteria after LT. We anticipate that these criteria will be useful in clinical practice to guide patient discharge and increase the comparability of results between future studies.

BACKGROUND & AIMS: Liver macrosteatosis (MS) is a major predictor of graft dysfunction after transplantation. However, frozen section techniques to quantify steatosis are often unavailable in the context of procurements, and the findings of preoperative imaging techniques correlate poorly with those of permanent sections, so that the surgeon is ultimately responsible for the decision. Our aim was to assess the accuracy of a non-invasive pocket-sized micro-spectrometer (PSM) for the real-time estimation of MS. METHODS: We prospectively evaluated a commercial PSM by scanning the liver capsule. A double pathological quantification of MS was performed on permanent sections. Initial calibration (training cohort) was performed on 35 livers (MSâ¯≤60%) and an algorithm was created to correlate the estimated (PSM) and known (pathological) MS values. A second assessment (validation cohort) was then performed on 154 grafts. RESULTS: Our algorithm achieved a coefficient of determination R2â¯=â¯0.81. Its validation on the second cohort demonstrated a Lin's concordance coefficient of 0.78. Accuracy reached 0.91%, with reproducibility of 86.3%. The sensitivity, specificity, positive and negative predictive values for MS ≥30% were 66.7%, 100%, 100% and 98%, respectively. The PSM could predict the absence (<30%)/presence (≥30%) of MS with a kappa coefficient of 0.79. Neither graft weight nor height, donor body mass index nor the CT-scan liver-to-spleen attenuation ratio could accurately predict MS. CONCLUSION: We demonstrated that a PSM can reliably and reproducibly assess mild-to-moderate MS. Its low cost and the immediacy of results may offer considerable added-value decision support for surgeons. This tool could avoid the detrimental and prolonged ischaemia caused by the pathological examination of (potentially) marginal grafts. This device now needs to be assessed in the context of a large-scale multicentre study. LAY SUMMARY: Macro-vacuolar liver steatosis is a major prognostic factor for outcomes after liver transplantation. However, it is often difficult for logistical reasons to get this estimation during procurement. Therefore, we developed an algorithm for a commercial, portable and affordable spectrometer to accurately estimate this content in a real-time fashion. This device could be of great interest for clinical decision-making to accept or discard a potential human liver graft.

BACKGROUND: After whole graft orthotopic liver transplantation (OLT), adaptation of the large grafts' volume to recipient weight is widely accepted despite the paucity of evidence on this subject. METHODS: Thirty nine patients with GRWR > 2.5% were included in this study and subsequently divided into two groups with 3 ≥ GRWR > 3%. Patients had CT scans at three predetermined time points after OLT used for measuring the liver volume. The objective of this study is to evaluate the volumetric changes of whole large liver grafts after adult OLT. RESULTS: At LT, the mean graft recipient body weight ratio (GRWR) was 3.1 ± 0.4%. The mean liver weight was 1881 ± 68 g at LT, 2014 ± 99 ml at one week, 1725 ± 126 ml at 3 months, and 1632 ± 117 (ml) at >6 months. There is an initial increase at 1 week after LT and a subsequent decrease of liver volume on later measurements. None of the late volume measurements were significantly different from the initial graft volume at liver transplant in pair wise comparisons ANOVA repeated measures (p > 0.05). Similarly, the mean GRWR did not change significantly between the initial calculation at transplantation date and the subsequent measurements during the different study time points (F = 0.04, p = 0.96) with a mean of 3.1% (95% CI = 2.2-4.2). AUC ROC discriminated a cutoff of 3% for the initial GRWR above which grafts tend to decrease in size over time (c statistics = 0.74, p = 0.036). In a Clustered ANOVA repeated measures, there was no significant difference in the changes of liver volume between both groups. However, patients with GRWR > 3 showed a trend towards a latent reduction in volume over the tracing period. There was a tendency, but none significant; towards a higher bilirubin, AST, ALT levels over the first postoperative days in recipients with GRWR > 3. CONCLUSION: Large grafts do not significantly decrease in size. Nonetheless, grafts weighing >3% of the GRWR show a different trend towards decrease in size over time.

BACKGROUND: Malnutrition is an independent risk factor of postoperative morbidity and mortality and it's observed in 20 to 50% of surgical patients. Preoperative interventions to optimize the nutritional status, reduce postoperative complications and enteral nutrition has proven to be superior to the parenteral one. Moreover, regardless of the nutritional status of the patient, surgery impairs the immunological response, thus increasing the risk of postoperative sepsis. Immunonutrition has been developed to improve the immunometabolic host response in perioperative period and it has been proven to reduce significantly postoperative infectious complications and length of hospital stay in patients undergoing elective gastrointestinal surgery for tumors. We hypothesize that a preoperative oral immunonutrition (ORAL IMPACT®) can reduce postoperative morbidity in liver resection for cancer. METHODS/DESIGN: Prospective multicenter randomized placebo-controlled double-blind phase IV trial with two parallel treatment groups receiving either study product (ORAL IMPACT®) or control supplement (isocaloric isonitrogenous supplement--IMPACT CONTROL®) for 7 days before liver resection for cancer. A total of 400 patients will be enrolled. Patients will be stratified according to the type of hepatectomy, the presence of chronic liver disease and the investigator center. The main end-point is to evaluate in intention-to-treat analysis the overall 30-day morbidity. Secondary end-points are to assess the 30-day infectious and non-infectious morbidity, length of antibiotic treatment and hospital stay, modifications on total food intake, compliance to treatment, side-effects of immunonutrition, impact on liver regeneration and sarcopenia, and to perform a medico-economic analysis. DISCUSSION: The overall morbidity rate after liver resection is 22% to 42%. Infectious post-operative complications (12% to 23%) increase the length of hospital stay and costs and are responsible for a quarter of 30-day mortality. Various methods have been advocated to decrease the rate of postoperative complications but there is no evidence to support or refute the use of any treatment and further trials are required. The effects of preoperative oral immunonutrition in non-cirrhotic patients undergoing liver resection for cancer are unknown. The present trial is designed to evaluate whether the administration of a short-term preoperative oral immunonutrition can reduce postoperative morbidity in non-cirrhotic patients undergoing liver resection for cancer. TRIAL REGISTRATION: Clinicaltrial.gov: NCT02041871.

OBJECTIVE: To integrate the amount of hepatic steatosis in modern liver allocation models. BACKGROUND: The aim of this study was to combine the 2 largest liver transplant databases (United States and Europe) in 1 comprehensive model to predict outcome after liver transplantation, with a novel focus on the impact of the presence of steatosis in the graft. METHODS: We adjusted the balance of risk (BAR) score for its application to the European Liver Transplant Registry (ELTR) database containing 11,942 patients. All liver transplants from ELTR and United Network for Organ Sharing with recorded liver biopsies were then combined in one survival analysis in relation to the presence of graft micro- (n = 9,677) and macrosteatosis (n = 11,516). RESULTS: Microsteatosis, regardless of the amount, was associated with a similar relationship between mortality and BAR score as nonsteatotic livers. Low-grade macrosteatotic liver grafts (≤30% macrosteatosis) resulted in 5-year graft-survival rates of 60% or more up to BAR 18, comparable to nonsteatotic grafts. However, use of moderate or severely steatotic liver grafts (>30% macrosteatosis) resulted in acceptable outcome only if the cumulative risk at transplant was low, that is, BAR score of 9 or less. CONCLUSIONS: Microsteatotic or 30% or less macrosteatotic liver grafts can be used safely up to BAR score of 18 or less, but liver grafts with more than 30% macrosteatotis should be used with risk adjustment, that is, up to BAR score of 9 or less.

BACKGROUND: As the real clinical significance of carcinoembryonic antigen (CEA) and carbohydrate antigen 19.9 (CA19.9) evolution during preoperative chemotherapy for colorectal liver metastases (CLM) is still unknown, we explored the correlation between biological and radiological response to chemotherapy, and their comparative impact on outcome after hepatectomy. METHODS: All patients resected for CLM at our hospital between 1990 and 2004 with the following eligibility criteria were included in the study: (1) preoperative chemotherapy, (2) complete resection of CLM, (3) no extrahepatic disease, and (4) elevated baseline tumor marker values. A 20% change of tumor marker levels while on chemotherapy was used to define biological response (decrease) or progression (increase). Correlation between biological and radiological response at computed tomography (CT) scan, and their impact on overall survival (OS) and progression-free survival (PFS) after hepatectomy were determined. RESULTS: Among 119 of 695 consecutive patients resected for CLM who fulfilled the inclusion criteria, serial CEA and CA19.9 were available in 113 and 68 patients, respectively. Of patients with radiological response or stabilization, 94% had similar biological evolution for CEA and 91% for CA19.9. In patients with radiological progression, similar biological evolution was observed in 95% of cases for CEA and in 64% for CA19.9. On multivariate analysis, radiological response (but not biological evolution) independently predicted OS. However, progression of CA19.9, but not radiological response, was an independent predictor of PFS. CONCLUSIONS: In patients with CLM and elevated tumor markers, biological response is as accurate as CT imaging to assess "clinical" response to chemotherapy. With regards to PFS, CA19.9 evolution has even better prognostic value than does radiological response. Assessment of tumor markers could be sufficient to evaluate chemotherapy response in a nonsurgical setting, limiting the need of repeat imaging.

Over the years, an improving liver transplant (LT) survival rate (1- and 5-year survival of 83% and 75%, respectively) has been instrumental in establishing transplant surgery as a durable therapy for all forms of end-stage liver disease and for some malignant conditions. The success of such treatment has resulted in a progressively increasing demand for liver transplantation. However, at the same time the availability of donor organs has diminished, resulting in the number of potential recipients for liver transplantation exceeding organ supply. Several strategies have been explored with the aim to increase access to liver transplantation, including: obtaining organs from non-heart-beating donors and live donors, and splitting and using livers from expanded donor criteria. This article discusses the utility of the mentioned techniques along with other strategies (e.g., Model for End-Stage Liver Disease [MELD] score), as well as the evolution of indications, contraindications, and postoperative care.

INTRODUCTION: For liver transplant candidates with hepatocellular carcinoma (HCC), the ability of neoadjuvant transarterial chemoembolization (TACE) to improve outcomes remains unproven. The objective of our study was to determine if there was a specific time interval where neoadjuvant TACE would decrease the number of HCC patients removed from the pretransplant waitlist. MATERIALS AND METHODS: A decision model was developed to simulate a randomized trial of neoadjuvant treatment with TACE vs. no TACE in 600 virtual patients with HCC and cirrhosis. Transition probabilities for TACE morbidity (1 +/- 1%), TACE response rates (30 +/- 20%), and disease progression (7 +/- 7% per month) were assigned by systematic review of the literature (18 reports). Sensitivity analyses were performed to determine time thresholds where TACE would decrease the number of delisted patients. RESULTS: TACE treatment had statistical benefit at waitlist time breakpoints of 4 and 9 months (P < 0.05). When waitlist times were less than 4 months, waitlist attrition was similar (20% vs. 34%, P = 0.08). When waitlist times exceed 9 months, waitlist dropout rates re-equilibrated (33% vs. 46%, P = 0.06). Review of the current literature determined that only those studies reporting on patients with waitlist times between 4 and 9 months found a benefit to neoadjuvant TACE. CONCLUSIONS: This analysis indicates that the benefit of neoadjuvant TACE may be limited to those patients transplanted from 4 to 9 months from first TACE. These data may help transplant programs to tailor TACE treatments based on predicted waitlist times to achieve optimal resource utilization and improved organ allocation efficiency.

BACKGROUND: The number of registries is increasing, but few of them perform reliability audits by comparing the data contained in the database with data contained in hospital charts. METHODS: The European Liver Transplant Registry (ELTR) cocoordinating committee appointed an independent team to check the reliability of data contained in ELTR. Centers were selected at random. Ten percent of each center's files were selected at random, and 25 items per file were checked during the site visits. The rates of completeness and inconsistencies and the agreement between ELTR and charts were established. We also assessed the correlation between the quality of data and the visited centers' activity. RESULTS: Seven hundred thirty-four files from 21 centers have been audited between June 1998 and June 2001. The rate of ELTR completeness was 95%, and the rate of consistency between charts and ELTR was 98%. The agreement between the ELTR and charts review was very good for all conditions (kappa value < or =0.81). However, comparisons of rates between items indicated that specific items, mostly cause of death or graft failure and patient outcome, should be targeted for improvement. No significant correlation was found between the quality of data and the experience of visited centers. The mean (min-max) and median cost per audited file were EUR 60 (8-150) and EUR 44, respectively. CONCLUSION: The results of audit visits indicate that ELTR data are reliable, and the scientific results of ELTR can be considered credible and representative of liver transplantation in Europe. The method could serve as a model for auditing a registry.

We assessed the impact of liver transplantation (LT) on the quality of life (QOL) of French recipients 1 year after surgery. A French version of the questionnaire used by the National Institute of Diabetes and Digestive and Kidney Disease-Pittsburg, USA (NIDDK), was validated by the back-translation method. Five QOL domains were evaluated: measures of disease, psychological distress, personal function, social function, and general health perception. Patients enrolled onto the waiting list completed the questionnaire before and 1 year after LT. Respondents were age- and gender-matched with healthy subjects recruited from the general population (GP). One year after LT, the analysis of data from 67 consecutive patients showed dramatic improvement in the five domains. Compared with baseline, patients noted fewer disease-related symptoms (P <.0001) and lower level of distress overall (P <.001). However, levels of distress caused by excess appetite (P <.01), trembling (P <.05), and headaches (P =.06) were more likely to increase than decrease. Twenty-five percent of patients prevented by their disease from going to work before LT were no longer so limited at 1-year follow-up. General health perception improved remarkably, with seven times as many recipients reporting improved health as reporting worse health. A correlation was found between the pretransplantation severity of cirrhosis and the social and role function after LT (P <.05). In summary, the French version of the NIDDK questionnaire seems to be reliable. The results of transplant recipients were generally close to those of the general population. Although it is not a true return to normal status, it approaches it.

OBJECTIVE: To determine the patient factors affecting patient outcome of first liver retransplantation at a single center to help in the decision process for retransplantation. SUMMARY BACKGROUND DATA: Given the critical organ shortage, one of the most controversial questions is whether hepatic retransplantation, the only chance of survival for patients with a failing first organ, should be offered liberally despite its greater cost, worse survival, and the inevitable denial of access to primary transplantation to other patients due to the depletion of an already-limited organ supply. The authors' experience of 139 consecutive retransplantations was reviewed to evaluate the results of retransplantation and to identify the factors that could improve the results. METHODS: From 1986 to 2000, 1,038 patients underwent only one liver transplant and 139 patients underwent a first retransplant at the authors' center (first retransplantation rate = 12%). Multivariate analysis was performed to identify variables, excluding intraoperative and donor variables, associated with graft and patient long-term survival following first retransplantation. Lengths of hospital and intensive care unit stay and hospital charges incurred during the transplantation admissions were compared for retransplanted patients and primary-transplant patients. RESULTS: One-year, 5-year, and 10-year graft and patient survival rates following retransplantation were 54.0%, 42.5%, 36.8% and 61.2%, 53.7%, and 50.1%, respectively. These percentages were significantly less than those following a single hepatic transplantation at the authors' center during the same period (82.3%, 72.1%, and 66.9%, respectively). On multivariate analysis, three patient variables were significantly associated with a poorer patient outcome: urgency of retransplantation (excluding primary nonfunction), age, and creatinine. Primary nonfunction as an indication for retransplantation, total bilirubin, and factor II level were associated with a better prognosis. The final model was highly predictive of survival: according to the combination of the factors affecting outcome, 5-year patient survival rates varied from 15% to 83%. Retransplant patients had significantly longer hospital and intensive care unit stays and accumulated significantly higher total hospital charges than those receiving only one transplant. CONCLUSIONS These data confirm the utility of retransplantation in the elective situation. In the emergency setting, retransplantation should be used with discretion, and it should be avoided in subgroups of patients with little chance of success.
