Infrarenal versus supraceliac aorto-hepatic arterial revascularisation in adult liver transplantation: multicentre retrospective study.

When the standard arterial reconstruction is not feasible during liver transplantation (LT), aorto-hepatic arterial reconstruction (AHAR) can be the only solution to save the graft. AHAR can be performed on the infrarenal (IR) or supraceliac (SC) tract of the aorta, but the possible effect on outcome of selecting SC versus IR reconstruction is still unclear. One hundred and twenty consecutive patients who underwent liver transplantation with AHAR in six European centres between January 2003 and December 2018 were retrospectively analysed to ascertain whether the incidence of hepatic artery thrombosis (HAT) was influenced by the type of AHAR (IR-AHAR vs. SC-AHAR). In 56/120 (46.6%) cases, an IR anastomosis was performed, always using an interposition arterial conduit. In the other 64/120 (53.4%) cases, an SC anastomosis was performed; an arterial conduit was used in 45/64 (70.3%) cases. Incidence of early (≤ 30 days) HAT was in 6.2% (4/64) in the SC-AHAR and 10.7% (6/56) IR-AHAR group (p = 0.512) whilst incidence of late HAT was significantly lower in the SC-AHAR group (4.7% (3/64) vs 19.6% (11/56) - p = 0.024). IR-AHAR was the only independent risk factor for HAT (exp[B] = 3.915; 95% CI 1.400-10.951; p = 0.009). When AHAR is necessary at liver transplantation, the use of the supraceliac aorta significantly reduces the incidence of hepatic artery thrombosis and should therefore be recommended whenever possible.

Risk Factors for Early Mortality in Liver Transplant Patients.

BACKGROUND: Liver transplantation (LT) is an established treatment for patients with end-stage liver disease. The significant advances in surgical technique, immunosuppression therapy, and anesthesiological management have dramatically improved short- and long-term outcomes. The aim of this study is to correlate specific surgical and anesthesiological variables with causes of early death in LT recipients. METHODS: A retrospective observational analysis of adult patients who underwent LT in the period 2012 to 2016 and died within 90 days following LT was conducted. Exclusion criteria were intraoperative death, split liver, and domino transplant. Death was considered a dependent variable and classified into 3 different groups: death by sepsis, vascular events not related to the graft, and primary non-function. Donor and recipient variables were considered and analyzed using Fisher's exact test. RESULTS: Statistically significative associations (P value < .05) were found between renal function support, retransplantation, and the number of fresh frozen plasma units transfused in one group and early death due to sepsis in the other. CONCLUSIONS: This study identified some risk factors associated with the specific cause of early death in liver transplantation. The clinical implications of these findings are the ability to stratify patients at high risk of early death by planning more intensive and accurate management for them.

Liver Retransplantation for Hepatic Abscess Due to Hepatic Artery Thrombosis: A Case Report.

INTRODUCTION: Hepatic artery thrombosis (HAT) is a well-recognized complication of liver transplantation (LT). HAT is an important risk factor for infectious, in particular hepatic abscess, which can cause graft loss and increasing morbidity and mortality. CASE REPORT: We present a case report of complicated LT in a 52-year-old Caucasian man with primary sclerosing cholangitis. In 2007 the patient was included on the waiting list in Padua for LT. In 2012 the patient underwent percutaneous transhepatic biliary drainage for bile duct stricture, complicated with acute pancreatitis. A diagnostic laparoscopy was performed with choledochotomy and Kehr's T tube drainage. On February 14, 2012, the patient underwent LT with arterial reconstruction and choledochojejunostomy. The postoperative course was complicated with HAT, multiple liver abscesses, and sepsis associated with bacteremia due to Enterococcus faecium despite massive intravenous antibiotic therapy and percutaneous drainages. On November 28, 2012, the patient underwent retransplantation. Four years after transplantation the patient is still in good general condition. CONCLUSION: Hepatic abscess formation secondary to HAT following LT is a major complication associated with important morbidity and mortality. In selected cases retransplantation should be considered as our case demonstrates.

Survival benefit of transplantation for recurrence of hepatocellular carcinoma after liver resection.

BACKGROUND: Liver transplantation (LT) for hepatocellular carcinoma (HCC) can be used for tumor recurrence after liver resection (LR) both for initially transplant-eligible patients as conventional salvage therapy (ST) and for non-transplant-eligible patients (beyond Milan criteria) with a goal of downstaging (DW). The aim of this study was to compare the intention-to-treat (ITT) survival rates of patients who are listed for LT, according to these two strategies. METHODS: We analyzed a prospective database of 399 consecutive patients who underwent hepatic resection for HCC from 2002 to 2011 to identify patients included in the waiting list for tumor recurrence. Intention-to-treat (ITT) survivals were compared with those of patients resected for HCC within and beyond Milan criteria in the same period and not included in the LT waiting list. RESULTS: The study group consisted of 42 patients, 28 in the ST group (within Milan) and 14 in the DW group (beyond Milan). The 5-year ITT survival rate was similar between the 2 groups, being 64% for ST and 60% for DW (P=.84). Twenty-five patients (15 ST and 10 DW) underwent LT, 13 (10 ST and 3 DW) were still awaiting LT, 4 (3 ST and 1 DW) dropped out of the waiting list because of tumor progression, and 7 (5 ST [33%] and 2 DW [20%]) had tumor recurrence. The 5-year ITT survival of ST patients was similar to that of 252 in-Milan HCC patients resected only (P=.3), whereas 5-year ITT survival of DW patients was significantly higher (P<.01) than that of 105 beyond-Milan HCC patients resected only. CONCLUSIONS: LR seems to be a safe and effective therapy both as alternative to transplantation and as downstaging strategy for intermediate-advanced HCC. The survival benefit of salvage LT, however, seems to be higher in the 2nd than in the 1st group.

SERPINB3 is associated with TGF-ß1 and cytoplasmic ß-catenin expression in hepatocellular carcinomas with poor prognosis.

BACKGROUND: Hepatocellular carcinoma (HCC) is one of the most important sanitary problems for its prevalence and poor prognosis. To date, no information is available on the prognostic value of the ov-serpin SERPINB3, detected in primary liver cancer but not in normal liver. The aim of the study was to analyse SERPINB3 expression in liver cancer in relation with molecular signatures of poor prognosis and with clinical outcome. METHODS: Liver tumours of 97 patients were analysed in parallel for SERPINB3, TGF-ß and ß-catenin. In a subgroup of 67 patients with adequate clinical follow-up, the correlation of molecular findings with clinical outcome was also carried out. RESULTS: High SERPINB3 levels were detectable in 22% of the patients. A significant correlation of this serpin with TGF-ß at transcription and protein level was observed, whereas for ß-catenin a strong correlation was found only at post-transcription level. These findings were in agreement with transcriptome data meta-analysis, showing accumulation of SERPINB3 in the poor-prognosis subclass (S1). High levels of this serpin were significantly associated with early tumour recurrence and high SERPINB3 was the only variable significantly associated with time to recurrence at multivariate analysis. CONCLUSIONS: SERPINB3 is overexpressed in the subset of the most aggressive HCCs.

Use of grafts from anti-HBc-positive donors in liver transplantation: a 5-year, single-center experience.

INTRODUCTION: Liver transplantation (OLT) is the treatment of choice for advanced hepatic disease. The growing gap between waiting list patients and the number of donations has led to acceptance of less than optimal donors. The aim of this study was to evaluate the 5-year experience with anti hepatitis B core antigen (HBc)-positive liver donors. PATIENTS AND METHODS: All recipients of anti-HBc-positive grafts from January 2005 to December 2010 were evaluated annually after OLT for liver disease etiology, Model for End-Stage Liver Disease (MELD) score, and the presence of hepatocellular carcinoma (HCC) liver biopsy histology and serology for hepatitis B virus (HBsAg, anti-HBs, HBV-DNA), hepatitis C virus, and hepatitis D virus as well as antiviral prophylaxis to prevent de novo HBV. RESULTS: Among the 249 OLT performed from January 2005 to December 2010, (9.3%) cases used grafts from anti-HBc-positive donors. Etiologics of liver disease among the recipients were HBV (n = 13; 32.5%), HCV (n = 13; 32.5%) or other causes (n = 14; 35%). In 20 of the 40 patients (50%), HCC was found in the explanted organ. Of 40 recipients of anti-HBc-positive grafts 11 died, and 7 (17.5%) required retransplantation. Various regimens were employed as post-transplantation antiviral prophylaxis: (l) Immune globulin (25.8%); (2) Oral antiviral drugs (9.7%); and (3) combined prophylaxis (51.6%) or no treatment (12.9%). No difference was observed in patient or graft survival in relation to the etiology of liver disease, the MELD score, or the presence of HCC at the time of OLT, except graft survival was significantly reduced among recipient who underwent transplantation for non-HBV or non-HCV liver diseases compared with those engrafted due to viral hepatitis (P = .0062). No difference was observed in histologic features (grading and staging) compared with the antiviral prophylactic therapy; the 2 patients (5%) who developed de novo HBV had not received prophylaxis after OLT. CONCLUSIONS: Matching anti-HBc-positive grafts to recipients without HBV infection before OLT, may be especially safe.

Liver autotransplantation for the treatment of unresectable hepatic metastasis: an uncommon indication-a case report.

Ex situ ex vivo liver surgery represents a method to expand the surgical indications to treat otherwise unresectable liver tumors. We report the case of a 38-year old woman with hepatic metastasis from a pancreatoblastoma that was judged to be unresectable due to the involvement of the three hepatic veins. To treat the primary tumor, she underwent a pancreaticoduodenectomy, adjuvant chemotherapy, and thermal ablation of a liver metastasis. After appropriate preoperative study and with the permission of the ethics committee, she underwent ex situ ex vivo liver resection. The hepatectomy was performed by removing the whole liver en bloc with the retrohepatic vena cava. The inferior vena cava was reconstructed by interposition of a prosthetic graft. The ex situ ex vivo hepatic resection, a left hepatic lobectomy included the lesion in segments 1-5-7-8. The two hepatic veins were reconstructed using patches of saphenous vein. The organ was preserved continuously for 6 hours using hypothermic perfusion with 4°C Celsior solution. The liver was then reimplanted performing an anastomosis between the reconstructed hepatic veins and the caval prostheses. The patient was discharged at postoperative day 22 and is currently disease-free at 8 months after surgery and 44 months after the initial diagnosis. Ex situ, ex vivo liver surgery offers an additional option for patients with both primary and secondary liver tumors considered to be unresectable using traditional surgical approaches.

Sorafenib for the treatment of recurrent hepatocellular carcinoma after liver transplantation?

BACKGROUND: There are scarce data on the use of sorafenib for the treatment of recurrent hepatocellular carcinoma (HCC) after orthotopic liver transplantation (OLT). PATIENTS AND METHODS: Ten patients were treated with sorafenib after OLT following the Italian Drug Agency guidelines: they had well-compensated liver function (Child-Pugh class A in the case of cirrhosis), intermediate-or advanced-stage HCC, good general condition (performance status 0), and not suitable for loco-regional therapies. Patients with HCC recurrence after OLT were treated with sorafenib (400 mg twice daily). Adverse events (AEs) were assessed using National Cancer Institute Common Toxicity Criteria of Adverse Events (NCI-CTCAE) v3.0 with tumor responses evaluated acording to modified Response Evaluation Criteria in Select Tumors) criteria. RESULTS: Median duration of treatment was 10 months (range, 2-18). Seven patients (70%) received an additionally targeted therapy with mTOR inhibitors as part of their immunosuppressive regimen. Most common grade 3 AEs included diarrhea (50%), hand-foot skin reaction (30%), and fatigue (20%). Sorafenib had to be discontinued in 3 patients (30%) due to AEs and 4 additional patients (40%) required a dose adjustment. No deterioration of liver graft function occurred. Three patients (30%) stopped treatment due to radiological progression of HCC, whereas 3 are still using the drug. Median time to progression was 8 months (range, 2-16). Median survival from start of therapy was 18 months (range, 4- 36). CONCLUSION: Our preliminary results suggest that sorafenib is a safe effective therapy for recurrent HCC after OLT.

Noninvasive high-frequency percussive ventilation in the prone position after lung transplantation.

Noninvasive positive-pressure ventilation (NIV), which represents a consolidated treatment of both acute and chronic respiratory failure, is increasingly being used to maintain spontaneous ventilation in lung transplant patients with impending pulmonary complications. Adding a noninvasive inspiratory support plus positive end-expiratory pressure (PEEP) has proven to be useful in preventing endotracheal mechanical ventilation, airway injury, and infections. Lung recipients with closure of the small airways in the dependent regions may also benefit from the prone position, which is helpful to promote recruitment of nonaerated alveoli and faster healing of consolidated atelectatic areas. In patients with localized or diffuse lung infiltrates, high-frequency percussive ventilation (HFPV), by either an invasive airway or a facial mask, has been adopted as an alternative ventilatory mode to enhance airway opening, limit potential respirator-associated lung injury, and improve mucus clearance. In nonintubated lung recipients at risk for volubarotrauma with conventional mechanical ventilation, it allows oxygen diffusion into the distal airways at lower mean airway pressures while avoiding repetitive cyclical opening and closing of the terminal airways. We summarize the clinical course of 3 patients with post-lung transplantation respiratory complications who were noninvasively ventilated with HFPV in the prone position. Major advantages of this treatment included gradual improvement of spontaneous clearance of bronchial secretions, significant attenuation of graft infiltrates and consolidations, a reduction in the number of bronchoscopies required, a decrease in spontaneous respiratory rate and work of breathing, and a significant improvement in gas exchange. The patients found HFPV with either standard facial mask or total mask interface to be comfortable or only mildly uncomfortable, and after the sessions they felt more restored. HFPV by facial mask in the prone position may be an interesting and attractive alternative to standard NIV, one that is more useful when implemented before full-blown respiratory failure is established.

Liver transplantation for massive hepatomegaly due to polycystic liver disease: an extreme case.

BACKGROUND: Polycystic liver disease (PLD) is due to a genetic disorder and frequently coexists with polycystic kidney disease (PKD). If the cysts produce symptomatology owing to their number and size, many palliative treatments are available. When none of the liver parenchyma is spared, or kidney insufficiency is marked, the only potentially curable treatment is liver transplantation (LT). CASE REPORT: A 49-year old woman, diagnosed with PLD and PKD, was listed in January 2008 for combined LT and kidney transplantation (KT). A compatible organ became available 8 months later. Despite preserved liver function, the patient's clinical condition was poor; she experienced dyspnea, advanced anorexia, abdominal pain, and severe ascites. At LT, which took 9 hours and was performed using the classic technique, the liver was hard, massive in size (15.5 kg), and not dissociable from the vena cava. The postoperative course was complicated by many septic episodes, the last one being fatal for the patient at 4 months after transplantation. DISCUSSION: LT for PLD in many series shows a high mortality rate. The Model for End-Stage Liver Disease (MELD) score does not stage patients properly, because liver function is usually preserved. The liver can achieve a massive size causing many symptoms, especially malnutrition and ascites; in this setting LT is the only possible treatment. Patients with a low MELD score undergo LT with severe malnutrition that predisposes them to greater susceptibility to sepsis. To identify predictor factors, beyond MELD criteria that relate to the increased liver volume before development of late symptoms is essential to expeditiously treat patients with the poorest prognosis to improve their outcomes.

Intensive care unit admission of decompensated cirrhotic patients: prognostic scoring systems.

Cirrhotic patients who need critical care support show high morbidity and mortality rates compared with other critically ill patients. Their prognosis is, in fact, influenced by both the severity of the underlying hepatic disease and the worsening of extrahepatic organ function. Clinicians and investigators have been persistently looking for objective scoring systems capable of providing accurate information on disease severity and short-term prognosis. Risk stratification helps differentiate patients who would not benefit from admission to the intensive care unit (ICU) from those who could achieve better outcomes once aggressively treated. The most common scores, ie, multiple organ dysfunction score, sequential organ failure assessment, and acute physiology and chronic health evaluation, developed in general ICUs to evaluate illness severity, have also been validated to predict the prognosis of cirrhotic patients admitted to the ICU. However, their absolute predictive value has been questioned. A weakness of common prediction models consists in not recognizing the continuum of physiological changes in critically ill decompensated cirrhotic patients. In addition, the predictive power to stratify individual risk is relatively low due to the great variability of liver dysfunction stages, the severity of related manifestations, and the number of nonfunctioning organs on admission. Probability models are not capable of predicting whether a patient will live or die with 100% accuracy, nor can they deny or confirm the indications for mechanical ventilation, vasopressor support or renal replacement therapy, or help to decide when to withhold or withdraw support. Because there are no absolute criteria to predict which cirrhotic decompensated patients will improve with normalization of organ function or deteriorate progressively, a scoring system should be regarded as an adjunct rather than a substitute for clinical judgment in the decision process concerning whether a patient should be admitted to the ICU.

Microwave thermal ablation for hepatocarcinoma: six liver transplantation cases.

Surgical resection for malignant hepatic tumors, especially hepatocarcinoma (HCC), has been demonstrated to increase overall survival; however, the majority of patients are not suitable for resection. Radiofrequency ablation (RFA) is the most widely used modality for radical treatment of small HCC (<3 cm). It improves 5-year survival compared with standard chemotherapy and chemical ablation, allowing down-staging of unresectable hepatic masses. Microwave ablation (MWA) has been extensively applied in Asia and was recently introduced in the United States of America and Europe with excellent results, especially with regard to large unresectable HCC. Our single-center experience between May 2009 and October 2010 included application of MWA to 154 patients of median age ± standard deviation of 63.5 ± 8.5 years, 6 males, and 1 female, of mean Model for End-Stage Liver Disease (MELD) score (10.1 ± 3.8). The HCC included, hepatitis C virus (HCV)-related (n=70; 45.5%); alcool (ETOH)-related (n=42; 27%), hepatitis B virus (HBV)-related (n=16; 10.5%); and cryptogenic cases (n=26; 17%). The cases were performed for radical treatment down-staging for multifocal pathology or bridging liver transplantation to orthotopic (OLT) in selected patients with single nodules. A computed tomography (CT) scan was performed at 1 month after the surgical procedure to evalue responses to treatment. Among 6 selected patients who underwent OLT; 5 (83.3%) showed disease-free survival at one-year follow-up. The radical treatment achieved no intraoperative evidence of tumor spread or of pathological signs of active HCC among the explanted liver specimens. In conclusion, a MWA seemed to be a safe novel approach to treat HCC and could serve as a "bridge" to OLT and down-staging for patients with HCC.

Risk factors in liver retransplantation: a single-center experience.

Liver retransplantation (Re-OLT) is one of the most debated issues in medicine over the past decade. Re-OLT, currently is accepted for patients with irreversible failure of a hepatic graft caused by primary nonfunction (PNF), hyperacute/chronic rejection, or hepatic artery thrombosis (HAT); whereas it is still controversial for patients with recurrent viral disease, in particular hepatitis C virus (HCV) cirrhosis. Patient and graft survival rates are lower than those observed after primary liver transplantation (OLT). The aim of the present study was to analyze the risk factors that adversely affect survival after Re-OLT in a single center. Medical data were collected for 23 patients who underwent Re-OLT from November 2002 to December 2008 including six men and seven women of mean age of 51.3 years. The most frequent indications for Re-OLT were: PNF (69.5%; 16/23), HCV recurrence (8.6%; 2/23), or HAT (8.6%; 2/23). Mean Model for End-Stage Liver Disease (MELD) at Re-OLT was 27.7 (range = 9-40). After a mean follow-up of 37.4 ± 30 (standard deviation) months, 43% (10/23) of patients had died, including 70% within the first 2 months after Re-OLT. Sepsis represented the commonest cause of death (40%). Re-OLT was performed for PNF among 90% of succumbing patients. As regards dead patients, 4/10 were HCV(+) whose causes of death were sepsis (n=2), alcoholic cirrhosis (n=2), and undetermined (n=1). Comparing patients who died after liver Re-OLT versus alive patients, we did not find any significant difference in terms of mean MELD (28.6 vs 27; P=NS), MELD > 25 (60% vs 61.5%, P=NS), donor age > 60 years (30% vs 15.3%, P=NS), HCV(+) (40% vs 62%, P = NS), or time interval from OLT to Re-OLT (12.2 vs 777.7 days, P=NS). Patient survivals after Re-OLT were 67% at 3 years and 50% at 5 years, which were lower than those of first transplantations, as reported by other European and International Centers. Forty percent of deaths after Re-OLT occurred among HCV(+) recipients, but for reasons unrelated to HCV infection.

Neoadjuvant therapy protocol and liver transplantation in combination with pancreatoduodenectomy for the treatment of hilar cholangiocarcinoma occurring in a case of primary sclerosing cholangitis: case report with a more than 8-year disease-free survival.

Cholangiocarcinoma has historically represented a major contraindication to liver transplantation at many centers because of its high recurrence rate and low disease-free survival rate, even after radical surgery. Novel neoadjuvant therapy protocols combined with demolitive surgery and liver transplantation seem to achieve successful results in terms of overall and disease-free survivals. Surgery frequently seems to be unsatisfactory only for patients also suffering from chronic cirrhosis or end-stage liver disease. We have reported a case of hilar cholangiocarcinoma occurring in a case of primary sclerosing cholangitis treated with neoadjuvant radiochemotherapy and endoscopic brachytherapy, followed by liver transplantation combined with pancreatoduodenectomy, who has survived free of disease for >8 years.

Donor-Model for End-Stage Liver Disease and donor-recipient matching in liver transplantation.

BACKGROUND: The product between donor (D) age and recipient (R) Model for End-Stage Liver Disease (MELD) score at the moment of liver transplantation (LT) has been proposed as a potential D-R matching tool to reduce the risk of "futile" LT from using the MELD score as the main allocation tool. The aim of this study was to evaluate the prognostic ability of D-MELD among a cohort of Italian patients already selected for LT on the basis of a D-R matching philosophy. METHODS: We studied 303 consecutive adult patients undergoing first LT for chronic liver diseases with available D-MELD at the moment of LT from 2003 to 2009. Optimal donors were assigned to more severe cirrhotic patients (MELD ≥20); suboptimal organs were allocated to patients with hepatocellular carcinoma (HCC) not responsive to bridging therapies (specific priority score) or other exceptions with MELD <20. A suboptimal donor had age >70 years, severe steatosis by ultrasound, and/or body mass index >30 kg/m(2), partial liver, or hepatitis C (HCV) or B virus positivity. RESULTS: Characteristics of the study group were a median age of 55 years (range, 27-68 years), HCV positivity in 164 patients (54%), HCC in 134 patients (44%), partial liver use in 25 (8%), MELD 15 (range, 6-40), D-age of 56 years (range, 18-87 years), and median D-MELD score 826 (range, 126-2,988). Overall graft survival was 84%, 79%, and 77% at 1, 3, and 5 years after LT, respectively. Logistic regression did not show a significant correlation between graft failure and D-MELD score in the absence of a significant D-MELD cutoff. Cox regression with D-MELD as the continuous variable showed a hazard ratio (HR) of 0.99 (95% confidence interval [CI], 0.99-1.00; P=NS); and with D-MELD as a dichotomic variable (≥0 to <1,600) an HR of 0.98 (95% CI, 0.63-1.77; P=NS). CONCLUSION: The prognostic ability of D-MELD fails in OLT centers that use a more complex D-R matching policy.

A new liver autotransplantation technique using subnormothermic machine perfusion for organ preservation in a porcine model.

BACKGROUND: Hepatic resection is the gold standard of therapy for primary and secondary liver tumors, but few patients are eligible for this procedure because of the extent of their neoplasms. Improvements in surgical experience of liver transplantation (OLT), hepatic resection and preservation with sub-normothermic machine perfusion (MP) have prompted the development of a new model of large animal autotransplantation. METHODS: Landrace pigs were used in this experiment. After intubation, hepatectomy was performed according to the classic technique. The intrahepatic caval vein was replaced with a homologous tract of porcine thoracic aorta. The liver was perfused with hypothermic Celsior solution followed by MP at 20 °C with oxygenated Krebs solution. An hepatectomy was performed during the period of preservation, which lasted 120 minutes, then the liver was reimplanted into the same animal in a 90° counterclockwise rotated position. The anastomoses were performed in the classic sequence. Samples of intravascular fluid, blood and liver biopsies were obtained at the end of the period of preservation in MP and again at 1 and 3 hours after liver reperfusion to evaluate graft function and microscopic damage. RESULTS: All animals survived the procedure. The peak of aspartate aminotransferase was recorded 60 minutes after reperfusion and the peak of alanine aminotransferase and lactate dehydrogenase after 180 minutes. Histopathologic examination under the light microscope identified no necrosis or congestion. Intraoperative echo-color Doppler documented good patency of the anastomosis and normal venous drainage. CONCLUSION: This system made it possible to perform hepatic resections and vascular reconstructions ex situ while preserving the organ with mechanical perfusion (ex vivo, ex situ surgery). Improving surgical techniques regarding autotransplantation and our understanding of ischemia-reperfusion damage may enable the development of interesting scenarios for aggressive surgical treatment or radiochemotherapy options to treat primary and secondary liver tumors unsuitable for conventional in situ surgery.
