Right Ex-situ split grafts for adult liver transplantation - A Multicenter Benchmarking Analysis.

OBJECTIVE: To analyse outcomes after adult right ex-situ split graft liver transplantations (RSLT) and compare with available outcome benchmarks from whole liver transplantation (WLT). SUMMARY BACKGROUND DATA: Ex-situ SLT may be a valuable strategy to tackle the increasing graft shortage. Recently established outcome benchmarks in WLT offer a novel reference to perform a comprehensive analysis of results after ex-situ RSLT. METHODS: This retrospective multicenter cohort study analyzes all consecutive adult SLT performed using right ex-situ split grafts from 01.01.2014 to 01.06.2022. Study endpoints included 1 year graft and recipient survival, overall morbidity expressed by the comprehensive complication index (CCI©) and specific post-LT complications. Results were compared to the published benchmark outcomes in low-risk adult WLT scenarii. RESULTS: In 224 adult right ex-situ SLT, 1y recipient and graft survival rates were 96% and 91.5%, within the WLT benchmarks. The 1y overall morbidity was also within the WLT benchmark (41.8 CCI points vs. <42.1). Detailed analysis, revealed cut surface bile leaks (17%, 65.8% Grade IIIa) as a specific complication without a negative impact on graft survival. There was a higher rate of early hepatic artery thrombosis (HAT) after SLT, above the WLT benchmark (4.9% vs. ≤4.1%), with a significant impact on early graft but not patient survival. CONCLUSION: In this multicentric study of right ex-situ split graft LT, we report 1-year overall morbidity and mortality rates within the published benchmarks for low-risk WLT. Cut surface bile leaks and early HAT are specific complications of SLT and should be acknowledged when expanding the use of ex-situ SLT.

Intraoperative indocyanine green fluorescence imaging to predict early hepatic arterial complications after liver transplantation.

The purpose of this study was to propose an innovative intraoperative criterion in a liver transplantation setting that would judge arterial flow abnormality that may lead to early hepatic arterial occlusion, that is, thrombosis or stenosis, when left untreated and to carry out reanastomosis. After liver graft implantation, and after ensuring that there is no abnormality on the Doppler ultrasound (qualitative and quantitative assessment), we intraoperatively injected indocyanine green dye (0.01 mg/Kg), and we quantified the fluorescence signal at the graft pedicle using ImageJ software. From the obtained images of 89 adult patients transplanted in our center between September 2017 and April 2019, we constructed fluorescence intensity curves of the hepatic arterial signal and examined their relationship with the occurrence of early hepatic arterial occlusion (thrombosis or stenosis). Early hepatic arterial occlusion occurred in 7 patients (7.8%), including 3 thrombosis and 4 stenosis. Among various parameters of the flow intensity curve analyzed, the ratio of peak to plateau fluorescence intensity and the jagged wave pattern at the plateau phase were closely associated with this dreaded event. By combining the ratio of peak to plateau at 0.275 and a jagged wave, we best predicted the occurrence of early hepatic arterial occlusion and thrombosis, with sensitivity/specificity of 0.86/0.98 and 1.00/0.94, respectively. Through a simple composite parameter, the indocyanine green fluorescence imaging system is an additional and promising intraoperative modality for identifying recipients of transplant at high risk of developing early hepatic arterial occlusion. This tool could assist the surgeon in the decision to redo the anastomosis despite normal Doppler ultrasonography.

Complex Hepatectomy Under Total Vascular Exclusion of the Liver Preserving the Caval Flow with Portal Hypothermic Perfusion and Temporary Portacaval Shunt: A Proof of Concept.

BACKGROUND: Hypothermic liver perfusion decreases ischemia/reperfusion injury during hepatectomy under standard total vascular exclusion (TVE) of the liver. This surgery needs venovenous bypass and is hampered by high morbi-mortality. TVE preserving the inferior vena cava (IVC) flow is hemodynamically well tolerated but remains limited in duration when performed under liver normothermia. The objective of this study was to report the results of TVE preserving the caval flow, modified to allow hypothermic liver perfusion and obviate splanchnic congestion. PATIENTS AND METHODS: The technique, indicated for tumors abutting large tributaries of the hepatic veins but sparing their roots in IVC and the latter, was applied when TVE was anticipated to last for ≥ 60 min. It combines continuous TVE preserving the IVC flow with hypothermic liver perfusion and temporary portacaval shunt (PCS). Results are given as median (range). RESULTS: Vascular control was achieved in 13 patients with excellent hemodynamical tolerance. PCS was direct or via an interposed synthetic graft (five and eight cases, respectively). Liver temperature dropped to 16.5 (6-24) °C under perfusion of 2 (2-4) L of cold perfusate. TVE lasted 67 (54-125) min and 4.5 (0-8) blood units were transfused. Resection was major in nine cases and was complete in all cases. Five complications occurred in four patients, and the 90-day mortality rate was zero. CONCLUSIONS: This technique maintains stable hemodynamics and combines the advantages of in situ or ex situ standard TVE with hypothermic liver perfusion, without their inherent prolongation of ischemia time and need for venovenous bypass.

Repeat laparoscopic liver resection after an initial open hepatectomy.

BACKGROUND: Repeat open hepatectomy (ROH) for recurrent liver tumors is the preferred approach especially after initial open hepatectomy (OH). The aim of this study is to assess feasibility and safety of repeat laparoscopic hepatectomy (RLH) after initial OH in 2 high volume hepato-biliary hospitals. METHODS: Patients were retrieved from prospective data bases from 2012 to 2020. The patients were divided into two groups according to the approach used for repeat hepatectomy, ROH and RLH groups. RESULTS: Sixty-seven patients matched the criteria, 20 in RLH and 47 in ROH. Diagnoses were hepatocellular carcinoma in 52.3%, intrahepatic cholangiocarcinoma in 7.7% and colorectal liver metastases in 40%. Median operative time and blood loss were lower in RLH (199 vs 260 min, and 100 vs 400 ml respectively), as well as overall postoperative complications (20% vs 49%). There were 2 conversions (10%) due to adhesions and one died of postoperative pancreatitis in RLH. Median hospital stay was lower in RLH (5 vs 9 days). CONCLUSION: RLH is a feasible, safe technique and a realistic option to be considered in selected patients after previous OH. Early conversion should be considered when adhesions are more severe than expected.

European validation of the classification for the anticipated difficulty of liver transplantation.

BACKGROUND: Appropriate risk stratification for the difficulty of liver transplantation (LT) is essential to guide the selection and acceptance of grafts and avoid morbidity and mortality. METHODS: Based on 987 LTs collected from 5 centers, perioperative outcomes were analyzed across the 3 difficulty levels. Each LT was retrospectively scored from 0 to 10. Scores of 0-2, 3-5 and 6-10 were then translated into respective difficulty levels: low, moderate and high. Complications were reported according to the comprehensive complication index (CCI). RESULTS: The difficulty level of LT in 524 (53%), 323 (32%), and 140 (14%) patients was classified as low, moderate and high, respectively. The values of major intraoperative outcomes, such as cold ischemia time (p = 0.04) and operative time (p < 0.0001) increased gradually with statistically significant values among difficulty levels. There was a corresponding increase in CCI (p = 0.04), severe complication rates (p = 0.05) and length of ICU (p = 0.01) and hospital (p = 0.004) stays across the different difficulty levels. CONCLUSION: The LT difficulty classification has been validated.

Defining Surgical Difficulty of Liver Transplantation.

OBJECTIVE: To define technically Diff-LT. SUMMARY OF BACKGROUND DATA: Currently, there is no acknowledged definition of Diff-LT. METHODS: This retrospective study included all first consecutive liver-only transplantations performed in 2 centers from 2011 to 2015. Diff-LT was defined as the combination of the number of blood units transfused, cold ischemia time, and duration of operation, all at or above the median value of the entire population. The correlation of Diff-LT with short- (including the comprehensive complication index) and long-term outcomes was assessed. Outcomes were also compared to the 90-day benchmark cutoffs of LT. Predictors of Diff-LT were identified by multivariable analysis, first using only recipient data and then using all recipient, donor, graft, and surgical data. RESULTS: The study population included 467 patients. The incidence of Diff- LT was 18.8%. Diff-LT was associated with short-term outcomes, including the comprehensive complication index and mortality, but not with patient or graft long-term survival. Previous abdominal surgery, intensive care unitbound at the time of LT, split graft use, nonstandard arterial reconstruction, and porto-systemic shunt ligation were independent predictors of Diff-LT. The proportion of variables below the corresponding LT 90-day benchmark cutoffs was 8/13 (61.5%) for non-Diff-LT, and 4/13 (30.8%) for Diff-LT. CONCLUSIONS: Diff-LT, as defined, occurred frequently. Adjusting modifiable variables might decrease the risk of Diff-LT and improve the postoperative course. This definition of Diff-LT might be useful for patient information, comparison between centers and surgeons, and as a metric in future trials.

Towards refining the utility of dual (18F-FDG / 18F-Choline) PET/CT for the management of hepatocellular carcinoma: a tertiary center study.

BACKGROUND: The role of positron emission tomography/computed tomography (PET/CT) in hepatocellular carcinoma (HCC) management is not clearly defined. Our objective was to analyze the utility of dual-PET/CT (18F-FDG + 18F-Choline) imaging findings on the BCLC staging and treatment decision for HCC patients. METHODS: Between January 2011 and April 2019, 168 consecutive HCC patients with available baseline dual-PET/CT imaging data were retrospectively analyzed. To identify potential refinement criteria for surgically-treated patients, survival Kaplan-Meier curves of various standard-of-care and dual-PET/CT baseline parameters were estimated. Finally, multivariate cox proportional hazard ratios of the most relevant clinico-biological and/or PET parameters were estimated. RESULTS: Dual-PET/CT findings increased the score of BCLC staging in 21 (12.5%) cases. In 24.4% (N.=41) of patients, the treatment strategy was modified by the PET findings. Combining AFP levels at a threshold of 10 ng/mL with 18F-FDG or 18F-Choline N status significantly impacted DFS (P<0.05). In particular, the combined criteria of the N+ status assessed by 18F-Choline with AFP threshold of 10 ng/mL provided a highly predictive composite parameter for estimation of DFS according to multivariate analysis (HR=10.6, P<0.05). CONCLUSIONS: The 18F-Choline / AFP composite parameter appears promising, and further prospective studies are mandatory to validate its oncological impact.

Renoportal Anastomosis During Liver Transplantation in Patients With Portal Vein Thrombosis: First Long-term Results From a Multicenter Study.

OBJECTIVE: To evaluate the short- and long-term outcomes of RPA in a large multicentric series. SUMMARY BACKGROUND: The current knowledge on RPA for portal reconstruction during LT in patients with diffuse PVT and a large splenorenal shunt is poor and limited to case reports and small case series. METHODS: All consecutive LTs with RPA performed in 5 centers between 1998 and 2020 were included. RPA was physiological provided it drained the splanchnic venous return through a large splenorenal shunt (≥ 1 cm diameter). Complications of PHT, long-term RPA patency, and patient and graft survival were assessed. RPA success was achieved provided the 3 following criteria were all fulfilled: patients were alive with patent RPA and without clinical PHT. RESULTS: RPA was attempted and feasible in 57 consecutive patients and was physiological in 51 patients (89.5%). Ninety-day mortality occurred in 5 (8.5%) patients, and PHT-related complications occurred in 42.9% of patients. With a median follow-up of 63 months, the 1-, 3- and 5-year patient and graft survival rates were 87%, 83%, and 76% and 82%, 80%, and 73%, respectively. The primary and primary-assisted patency rates at 5 years were 84.5% and 94.3%, respectively. Success was achieved in 90% (27/30) of patients with a follow-up ≥5 years. CONCLUSIONS: Despite a high rate of PHT-related complications, excellent long-term patient and graft survival could be achieved. RPA could be considered successful in the vast majority of patients. The expanded use of RPA is warranted.

Novel Composite Endpoint for Assessing Outcomes in Liver Transplantation: Arterial and Biliary Complication-Free Survival.

Transplant and patient survival are the validated endpoints to assess the success of liver transplantation (LT). This study evaluates arterial and biliary complication-free survival (ABCFS) as a new metric. ABC, considered as an event, was an arterial or biliary complication of Dindo-Clavien grade ≥III complication dated at the interventional, endoscopic, or surgical treatment required to correct it. ABCFS was defined as the time from the date of LT to the dates of first ABC, death, relisting, or last follow-up (transplant survival is time from LT to repeat LT or death). Following primary whole LT (n = 532), 106 ABCs occurred and 99 (93%) occurred during the first year after LT. An ABC occurring during the first year after LT (overall rate 19%) was an independent factor associated with transplant survival (hazard ratio [HR], 3.17; P < 0.001) and patient survival (HR, 2.7; P = 0.002) in univariate and multivariate analyses. This result was confirmed after extension of the cohort to split-liver graft, donation after circulatory death, or re-LT (n = 658). Data from 2 external cohorts of primary whole LTs (n = 249 and 229, respectively) confirmed that the first-year ABC was an independent prognostic factor for transplant survival but not for patient survival. ABCFS was correlated with transplant and patient survival (ρ = 0.85 [95% CI, 0.78-0.90] and 0.81 [95% CI, 0.71-0.88], respectively). Preoperative factors known to influence 5-year transplant survival influenced ABCFS after 1 year of follow-up. The 1-year ABCFS was indicative of 5-year transplant survival. ABCFS is a reproducible metric to evaluate the results of LT after 1 year of follow-up and could serve as a new endpoint in clinical trials.

The rex shunt for left portal vein reconstruction during hepatectomy for malignancy using of rex-shunt in adults for oncoliver surgery.

BACKGROUND: Immediate portal reperfusion is mandatory following hepatectomy combined with portal vein (PV) resection. This retrospective study analyzes the feasibility and the outcomes of the Rex shunt (RS) for reconstruction of the left portal vein (LPV) and reperfusion of the remnant left liver or lobe following hepatectomy for cancer combined with resection of the PV in adult patients. METHODS: From 2018 to 2021, an RS was used in the above setting to achieve R0 resection or when the standard LPV reconstruction failed or was deemed technically impossible. RESULTS: There were 6 male and 5 female patients (median age, 58 years) with perihilar cancer (5 cases) or miscellaneous cancers invading the PV (6 cases). A major hepatectomy was performed in 10/11 patients. The RS was indicated to achieve R0 resection or for technical reasons in 8 and 3 cases, respectively, and was feasible in all consecutive attempts with (10 cases) or without an interposed synthetic graft (1 case). Two fatal complications (PV thrombosis and pulmonary embolism) and three non-severe complications occurred in four patients within 90 days of surgery. Two patients died of tumor recurrence with a patent RS at 13 and 29 months, and 7 were recurrence free with a patent shunt with a follow-up of 1 to 37 months (median, 15 months). CONCLUSION: In case of remnant left liver or lobe following hepatectomy combined with resection of the PV, the RS may help to achieve R0 resection and is a valuable option to perform technically satisfying portal reperfusion of the remnant left liver or lobe.

Tumors located in the central column of the liver are associated with increased surgical difficulty and postoperative complications following open liver resection for colorectal metastases.

BACKGROUND: To assess the impact of difficult location (based on preoperative computed tomography) of liver metastases from colorectal cancer (LMCRC) on surgical difficulty, and occurrence of severe postoperative complications (POCs). METHODS: A retrospective single-centre study of 911 consecutive patients with LMCRC who underwent hepatectomy by the open approach between 1998 and 2011, before implementation of laparoscopic surgery to obviate approach selection bias. LMCRC with at least one of the following four features on preoperative imaging: tumor invading the hepatocaval confluence or retro-hepatic inferior vena cava, centrally located (Segments 4,5,8) and >10 cm in diameter, abutting the supra-hilar area, or involving the paracaval portion or caudate process of Segment 1; were considered as topographically difficult (top-diff). Independent predictors of surgical difficulty assessed by number of blood units transfused, duration of ischemia, and number of sessions of pedicle clamping during surgery and of severe POCs were identified by multivariate analysis before, and after propensity score matching. RESULTS: Top-diff tumor location independently predicted surgical difficulty. Severe POCs were associated with the tumor location [top-diff vs. topographically non difficult (non top-diff)], preoperative portal vein embolization, and variables related to surgical difficulty. CONCLUSION: LMCRC in difficult location independently predicts surgical difficulty and severe POCs.

The impact of advanced patient age in liver transplantation: a European Liver Transplant Registry propensity-score matching study.

BACKGROUND: The futility of liver transplantation in elderly recipients remains under debate in the HCV eradication era. METHODS: The aim was to assess the effect of older age on outcome after liver transplantation. We used the ELTR to study the relationship between recipient age and post-transplant outcome. Young and elderly recipients were compared using a PSM method. RESULTS: A total of 10,172 cases were analysed. Recipient age >65 years was identified as an independent risk factor associated with reduced patient survival (HR:1.42 95%CI:1.23-1.65,p < 0.001). After PSM, 2124 patients were matched, and the same association was found between elderly recipients and patient survival and graft survival (p < 0.001). As hepatocellular carcinoma and alcoholic cirrhosis were independent prognostic factors for patient and graft survival a propensity score-matching was performed for each. Patient and graft survival were significantly worse (p < 0.05) in the alcoholic cirrhosis elderly group. However, patient and graft survival in the hepatocellular carcinoma cohort were similar (p > 0.05) between groups. CONCLUSION: Liver transplantation is an acceptable and safe curative option for elderly transplant candidates, with worse long-term outcomes compare to young candidates. The underlying liver disease for liver transplantation has a significant impact on the selection of elderly patients.

De novo hepatocellular carcinoma in a non-cirrhotic allograft 27 years after liver transplantation: A case report.

Hepatocellular carcinoma recurrence after liver transplantation is a well-known complication but the development of de novo hepatocellular carcinoma in non-cirrhotic allograft with no previous history of hepatic malignancy either in the donor or the recipient is extremely rare. A 33-year-old man underwent deceased donor liver transplantation due to HBV-HDV cirrhosis in 1991. The donor was healthy, with negative viral serology. Pretransplant assessment and explant liver pathology revealed no tumor. He developed an 8 cm mediastinal thymus cancer in 2014, a chronic myeloid leukemia in 2015 and a 16 mm renal cell carcinoma in 2017. After 27 years, in 2018, his routine follow-up sonography showed incidentally a 37 mm hepatic nodule in segment VII which revealed after percutaneous liver guided biopsy a hepatocellular carcinoma. As no extra hepatic metastasis was noted, segmentectomy was done. The pathological report confirmed a moderately differentiated hepatocellular carcinoma nodule of 50 mm diameter with absence of microvascular invasion and the non-tumoral liver showed histological features of NASH (SAF score: S1A2F3, NAS score: A3F3 and LAFSc:5) with absence of HBsAg and HBcAg. This case emphasizes the importance of long-term close surveillance by imaging of the graft even in the absence of viral recurrence and graft cirrhosis.

Outcomes after 3D laparoscopic and robotic liver resection for hepatocellular carcinoma: a multicenter comparative study.

BACKGROUND: The recent development of 3D vision in laparoscopic and robotic surgical systems raises the question of whether these two procedures are equivalent. The aim of this study was to evaluate the surgical and long-term oncological outcomes of 3D laparoscopic (3D-LLR) and robotic liver resection (RLR) for hepatocellular carcinoma (HCC). METHODS: The data for operative time, morbidity, margins, and survival were reviewed for 3D-LLR and compared with RLR. RESULTS: From 2011 to 2017, 93 patients with HCC, including 58 (62%) with cirrhosis, underwent 3D-LLR [49 (53%)] or RLR [44 (47%)]. No difference was observed in operative time (269 vs. 252 min; p = 0.52), overall (27% vs. RLR: 16%; p = 0.49) and severe morbidity (4% vs. 2%; p = 0.77) or in the surgical margin width (9 vs. 11 mm; p = 0.30) between the 3D-LLR and RLR groups. The 3-year overall and recurrence-free survival rates after 3D-LLR and RLR were 82% and 24% and 91% (p = 0.16) and 48% (p = 0.18), respectively. CONCLUSIONS: The 3D-LLR and RLR systems provide comparable surgical margins with similar short- and long-term oncological outcomes.

Textbook Outcome Following Liver Transplantation.

BACKGROUND: Textbook outcome (TBO) is a patient-oriented composite criterion achieved when all desired main health outcomes are realized. The aim was to assess the incidence and the independent factors associated with TBO following LT. METHODS: This bicentric study included all patients who underwent their first elective liver-only LT between 2011 and 2015. TBO occurred when all the following criteria were fulfilled: no mortality within 90 days, no major complications within 90 days, no reintervention within 90 days (liver graft biopsy, radiological, endoscopic or surgical interventions, or retransplantation), no prolonged intensive care unit stay, and no prolonged hospital stay. Univariable and multivariable analyses were performed to identify factors associated with TBO and to assess whether TBO is an independent factor associated with patient and graft survival. RESULTS: The study population included 530 patients. TBO occurred in 176/530 (33%) patients. Independent factors associated with TBO included the balance of risk score, the use of an intraoperative temporary portacaval shunt, and duration of the operation. TBO was identified as an independent factor associated with graft survival but not patient survival. CONCLUSIONS: TBO might be implemented in the patient-doctor decision-making regarding whether to proceed with LT and in the reporting of patient-level hospital performance related to LT.

Metastatic leiomyosarcoma of the inferior vena cava with long-time survival: therapeutic options.

A 70-year-old male diagnosed with leiomyosarcoma of the inferior vena cava level II, treated with radical resection with negative margins. An hepatic metastasis in segment II is found at the 5th year follow up (fig. 1). Given the good general condition of the patient, the long disease-free period and a single resectable metastasis, the surgical excision was decided. The leiomyosarcoma of the inferior vena cava is a rare tumor of mesenchymal origin. Margins free surgery is the only treatment that increases survival. However, this is the most unfeasible situation since the disease presentation is often with a spread tumor. The singularity of this case is the long disease-free period and a single liver metastasis as recurrence of the disease.

Indocyanine Green Fluorescence Imaging to Predict Graft Survival After Orthotopic Liver Transplantation: A Pilot Study.

The incidence of primary nonfunction (PNF) after liver transplantation (LT) remains a major concern with the increasing use of marginal grafts. Indocyanine green (ICG) fluorescence is an imaging technique used in hepatobiliary surgery and LT. Because few early predictors are available, we aimed to quantify in real time the fluorescence of grafts during LT to predict 3-month survival. After graft revascularization, ICG was intravenously injected, and then the fluorescence of the graft was captured with a near infrared camera and postoperatively quantified. A multiparametric modeling of the parenchymal fluorescence intensity (FI) curve was proposed, and a predictive model of graft survival was tested. Between July 2017 and May 2019, 76 LTs were performed, among which 6 recipients underwent retransplantation. No adverse effects of ICG injection were observed. The parameter a150 (temporal course of FI) was significantly higher in the re-LT group (0.022 seconds-1 (0.0011-0.059) versus 0.012 seconds-1 (0.0001-0.054); P = 0.01). This parameter was the only independent predictive factor of graft survival at 3 months (OR, 2.4; 95% CI, 1.05-5.50; P = 0.04). The best cutoff for the parameter a150 (0.0155 seconds-1 ) predicted the graft survival at 3 months with a sensitivity (Se) of 83.3% and a specificity (Spe) of 78.6% (area under the curve, 0.82; 95% CI, 0.67-0.98; P = 0.01). Quantitative assessment of intraoperative ICG fluorescence on the graft was feasible to predict graft survival at 3 months with a good Se and Spe. Further prospective studies should be undertaken to validate these results over larger cohorts and evaluate the clinical impact of this tool.

Liver transplantation in patients with sickle cell disease: possible but challenging-a cohort study.

The liver is frequently affected in patients with sickle cell disease (SCD), but few reports have described liver transplantation (LT) in patients with SCD. We present a thorough analysis of the largest single-center series of LT in patients with SCD and the first systematic review. There were 21 patients with a median age of 37.6 years. LT was performed for acute liver failure related to the sickling process (57%) or electively for end-stage liver disease (43%). Prior to LT, 13 patients (62%) were in the intensive care unit and required mechanical ventilation (33%), vasopressor therapy (24%), renal replacement therapy (10%), or molecular adsorbent recirculating system therapy (19%). Post-LT morbidity and mortality were 95% and 33%, respectively. Patient survival at 1 and 5 years were 58.3% and 41.7%, respectively, in the urgent group and 88.9% and 77.8%, respectively, in the elective group. A total of 22 transplant patients with SCD are described in 20 articles in the literature. The 1- and 5-year patient survival rates for the 18 evaluable patients were 75% and 65%, respectively. LT improves survival in patients with SCD and acute liver failure or end-stage liver disease but is associated with high morbidity during the early postoperative course.

Liver Transplantation with "Hors Tour" Allocated Versus Standard MELD Allocated Grafts: Single-Center Audit and Impact on the Liver Pool in France.

BACKGROUND: The French transplant governing system defined "Rescue" (the so-called "Hors Tour") livers as those livers which were declined for the five top-listed patients. This study compares the outcomes following liver transplantation (LT) in patients who received a donor liver through a rescue allocation (RA) procedure or according to MELD score priority (standard allocation, SA) and evaluates the impact on the graft pool of a proactive policy to accept RA grafts. METHODS: Data from all consecutive patients who underwent LT with SA or RA grafts from 2011 to 2015 were compared in terms of short- and long-term outcomes. RESULTS: The 249 elective first LTs were performed with 64 (25.7%) RA and 185 (74.3%) SA grafts. RA grafts were obtained from older donors and were associated with a longer cold ischemia time. Recipients of RA livers were older and had lower MELD scores. The rates of delayed graft function, primary nonfunction, retransplantation, complications, and mortality were similar between the RA and SA groups. At 1 and 3 and 5 years, graft and patient survival rates were similar between the groups. These results were maintained after matching on recipient characteristics. Our proactive policy to accept RA grafts increased the liver pool for elective first transplantation by 25%. CONCLUSIONS: RA livers can be safely transplanted into selected recipients and significantly expand the liver pool.

Laparoscopic Liver Resection for Hepatocellular Carcinoma in Child-Pugh A Patients With and Without Portal Hypertension: A Multicentre Study.

BACKGROUND: Laparoscopic liver resection (LLR) may improve outcomes for cirrhotic patients with hepatocellular carcinoma (HCC) and portal hypertension (PHT). The aim of this study was to compare the short-term outcomes after LLR for HCC in cirrhotic patients with and without PHT. METHODS: This multicentric study included 96 HCC patients who underwent LLR. Clinically significant portal hypertension (CSPH) was defined by a hepatic venous pressure gradient ≥10 mmHg. Short-term outcomes and liver-specific complications including post-hepatectomy liver failure (PHLF), ascites and encephalopathy were compared between patients with and without CSPH. RESULTS: Thirty-one patients (32%) had CSPH. The CSPH group had higher post-operative morbidity (52% vs. 15%; p < 0.001), PHLF (10% vs. 0%; p = 0.03) and encephalopathy (10% vs. 0%; p = 0.03). There was no difference in terms of post-operative ascites between the two groups (CSPH: 16% vs. no CPSH: 8%, p = 0.28). The length of stay was longer in patients with CSPH than in those without CSPH (6 vs. 4 days; p < 0.001). CONCLUSIONS: The laparoscopic approach is feasible in selected HCC patients with CSPH, at the price of significant increases in liver-specific complications and length of stay.
