RESUMEN

BACKGROUND: Split liver transplantation is a valuable means of mitigating organ scarcity but requires significant surgical and logistical effort. Ex vivo splitting is associated with prolonged cold ischemia, with potentially negative effects on organ viability. Machine perfusion can mitigate the effects of ischemia-reperfusion injury by restoring cellular energy and improving outcomes. METHODS: We describe a novel technique of full-left/full-right liver splitting, with splitting and reconstruction of the vena cava and middle hepatic vein, with dual arterial and portal hypothermic oxygenated machine perfusion. The accompanying video depicts the main surgical passages, notably the splitting of the vena cava and middle hepatic vein, the parenchymal transection, and the venous reconstruction. RESULTS: The left graft was allocated to a pediatric patient having methylmalonic aciduria, whereas the right graft was allocated to an adult patient affected by hepatocellular carcinoma and cirrhosis. CONCLUSIONS: This technique allows ex situ splitting, counterbalancing prolonged ischemia with the positive effects of hypothermic oxygenated machine perfusion on graft viability. The venous outflow is preserved, safeguarding both grafts from venous congestion; all reconstructions can be performed ex situ, minimizing warm ischemia. Moreover, there is no need for highly skilled surgeons to reach the donor hospital, thereby simplifying logistical aspects.

RESUMEN

Cancer of the body-tail of the pancreas often involves adjacent structures. Thus, surgical treatment may be extended to other organs or vessels in order to achieve radical resection. The aim of this study is to evaluate the safety and efficacy of extended distal pancreatectomy for ductal adenocarcinoma of the body and tail of the pancreas. Between January 2000 and December 2016, 101 patients underwent distal pancreatectomy (DP) for pancreatic cancer: 65 patients underwent standard-DP and 36 extended-DP, including the resection of the partial stomach (n = 12), adrenal gland (n = 7), liver (n = 7), colon (n = 8), celiac axis (n = 6), portal vein (n = 5), jejunum (n = 4) and kidney (n = 4). The two groups were compared in terms of their TNM classification, pathological grade, nodal status, state of resection margins, age, sex and levels of preoperative serum carbohydrate antigen 19-9 (CA 19.9). The morbidity and mortality were not statistically different in the two groups. The two groups disease-free and overall survival rates were significantly influenced by the tumor's stage, nodal status, pathological features and resection margins. Survival was not influenced by the extent of the surgical resection. However, when patients were stratified according to the type of extended resection, survival was worse in the group of patients undergoing vascular resection. Multivariate analysis showed that the stage and resection margins are independent predictors of disease-free and overall survival. Extended distal pancreatectomy may be performed with acceptable morbidity and mortality rates. Survival is not significantly different after standard or extended resection. However, the rate of tumor recurrence is high, and long-term survival is a rare event, especially in those patients who undergo distal pancreatectomy associated with vascular resection.

RESUMEN

In the context of spreading interest in textbook outcome (TO) evaluation in different fields, we aimed to investigate an uncharted procedure, that is, laparoscopic microwave ablation (MWA) for hepatocellular carcinoma (HCC). Absence of post-MWA complications, a hospital stay of three days, no mortality nor readmission within 30 days, and complete response of the target lesion at post-MWA CT scan defined TO achievement. Patients treated between January 2014 and March 2021 were retrospectively reviewed, and of the 521 patients eligible for the study, 337 (64.7%) fulfilled all the quality indicators to achieve the TO. The absence of complications was the main limiting factor for accomplishing TO. At multivariable analysis, Child-Pugh B cirrhosis, age of more than 70 years old, three nodules, and MELD score ≥ 15 were associated with decreased probabilities of TO achievement. A score based on these factors was derived from multivariable analysis, and patients were divided into three risk groups for TO achievement. At survival analysis, overall survival (OS) was significantly (p = 0.001) higher in patients who achieved TO than those who did not. Moreover, OS evaluation in the three risk groups showed a trend coherent with TO achievement probability. The present study, having assessed the first TO for laparoscopic MWA for HCC, encourages further broader consensus on its definition and, on its basis, on the development of clinically relevant tools for managing treatment allocation.

RESUMEN

In resected perihilar cholangiocarcinoma (PHC), positive ductal margin (DM) is associated with poor survival. There is currently little knowledge about the impact of positive radial margin (RM) when DM is negative. The aim of this study was to evaluate the incidence and the role of positive RM. Patients who underwent surgery between 2005 and 2017 where retrospectively reviewed and stratified according to margin positivity: an isolated RM-positive group and DM ± RM group. Of the 75 patients identified; 34 (45.3%) had R1 resection and 17 had positive RM alone. Survival was poorer in patients with R1 resection compared to R0 (p = 0.019). After stratification according to margin positivity; R0 patients showed better survival than DM ± RM-positive patients (p = 0.004; MST 43.9 vs. 23.6 months), but comparable to RM-positive patients (p = 0.361; MST 43.9 vs. 39.5 months). Recurrence was higher in DM ± RM group compared to R0 (p = 0.0017; median disease-free survival (DFS) 15 vs. 30 months); but comparable between RM and R0 group (p = 0.39; DFS 20 vs. 30 months). In univariate and multivariate analysis, DM positivity resulted as a negative prognostic factor both for survival and recurrence. In conclusion, positive RM resections appear to have different recurrence patterns and survival rates than positive DM resections.

RESUMEN

BACKGROUND: De novo metabolic syndrome (MS) is a frequent complication after liver transplantation (LT). The aim of this prospective study is to identify potential risk factors longitudinally associated to post-LT de novo MS. Patients without pre-LT MS who underwent LT between April 2013 and October 2017 were prospectively included. Metabolic variables were collected at LT and at 6, 12, and 24 months post-LT. RESULTS: Sixty-three patients fulfilled the inclusion criteria (76% male, mean age 53.6±9.5 years). The prevalence of de novo MS was 46%, 43%, and 49% at 6, 12, and 24 months after LT, respectively. Among other MS components, the prevalence of type 2 diabetes, hypertension and hypertriglyceridemia significantly increased after LT. Considering the baseline characteristics at the adjusted analysis, alcoholic liver disease (OR 4.17, 95%CI 1.20-14.51; p = .03) and hypertension pre-LT (OR 11.3, 95% CI 1.49-85.46; p = .02) were confirmed as independent risk factors of post-LT de novo MS. In the time-varying analysis, only eGFR (OR .97, 95% CI .97-.98; p < .0001) was found associated with post-LT de novo MS. CONCLUSIONS: De novo MS frequently occurs shortly after LT, affecting nearly half of patients at 24 months post-LT. Lifestyle modifications should be recommended starting early post-LT, particularly for patients with established risk factors.

RESUMEN

Background: In December 2019, an outbreak of pneumonia, caused by a new type of coronavirus, named severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). It quickly spread worldwide, resulting in a pandemic. The clinical manifestations of SARS-CoV-2 range from mild non-specific symptoms to severe pneumonia with organ function damage. In addition, up to 60% of patients have liver impairment or dysfunction, confirmed by several studies by the presence of SARS-CoV-2 in the liver tissue. Methods: We report two cases of symptomatic liver cyst requiring fenestration after recent SARS-CoV-2 infection. Both patients had hospital admission due to documented SARS-CoV-2 infection. Recently, after the infection, they developed symptoms caused by an enlarged hepatic cyst: one had abdominal pain, and the other had jaundice. They underwent surgery after two negative swab tests for SARS-CoV-2. Results: Cystic fluid was sent for microbiological test, and real-time fluorescence polymerase chain reaction COVID-19 nucleic-acid assay of the cyst fluid was found to be negative in both cases. Discussion: Although there are no current data that can document a viral contamination of cystic fluid, there are data that document a hepatotropism of COVID-19 virus. Herein we report that after viral clearance at pharyngeal and nasal swab, there is no evidence of viral load in such potential viral reservoir.

RESUMEN

The XXL trial represents the first prospective validation of "biological downstaging" in liver transplantation (LT) for hepatocellular carcinoma. The aim of this study was to compare the Padua downstaging protocol to the XXL protocol in terms of downstaging failure rates and patient outcome. A total of 191 patients undergoing aggressive surgical downstaging and potentially eligible for LT from 2012 to 2018 at our center were retrospectively selected according to XXL trial criteria. Unlike the XXL trial, patients with a complete response to downstaging did not receive any prioritization for LT. Downstaging failure was defined as stable progressive disease or post-treatment mortality. The statistical method of "matching-adjusted indirect comparison" was used to match the study group to the XXL population. Downstaging failure rate was considerably lower in the study group than in the XXL trial (12% vs. 32%, d value = |0.683|). The survival curves of our LT group (n = 68) overlapped with those of the LT-XXL group (p = 0.846). Survival curves of non-LT candidates with a sustained complete response (n = 64) were similar to those of transplanted patients (p = 0.281). Our study represents a validation of the current Padua and Italian policies of denying rapid prioritization to patients with complete response to downstaging. Such a policy seems to spare organs without worsening patient outcome.

RESUMEN

BACKGROUND: Donation after circulatory death (DCD) in Italy, given its 20-min stand-off period, provides a unique bench test for normothermic regional perfusion (NRP) and dual hypothermic oxygenated machine perfusion (D-HOPE). METHODS: We coordinated a multicenter retrospective Italian cohort study with 44 controlled DCD donors, who underwent NRP, to present transplant characteristics and results. To rank our results according to the high donor risk, we matched and compared a subgroup of 37 controlled DCD livers, preserved with NRP and D-HOPE, with static-preserved controlled DCD transplants from an established European program. RESULTS: In the Italian cohort, D-HOPE was used in 84% of cases, and the primary nonfunction rate was 5%. Compared with the matched comparator group, the NRP + D-HOPE group showed a lower incidence of moderate and severe acute kidney injury (stage 2: 8% versus 27% and stage 3: 3% versus 27%; P = 0.001). Ischemic cholangiopathy remained low (2-y proportion free: 97% versus 92%; P = 0.317), despite the high-risk profile resulting from the longer donor warm ischemia in Italy (40 versus 18 min; P < 0.001). CONCLUSIONS: These data suggest that NRP and D-HOPE yield good results in DCD livers with prolonged warm ischemia.

RESUMEN

Importance: Expansion of donor acceptance criteria for liver transplant increased the risk for early allograft failure (EAF), and although EAF prediction is pivotal to optimize transplant outcomes, there is no consensus on specific EAF indicators or timing to evaluate EAF. Recently, the Liver Graft Assessment Following Transplantation (L-GrAFT) algorithm, based on aspartate transaminase, bilirubin, platelet, and international normalized ratio kinetics, was developed from a single-center database gathered from 2002 to 2015. Objective: To develop and validate a simplified comprehensive model estimating at day 10 after liver transplant the EAF risk at day 90 (the Early Allograft Failure Simplified Estimation [EASE] score) and, secondarily, to identify early those patients with unsustainable EAF risk who are suitable for retransplant. Design, Setting, and Participants: This multicenter cohort study was designed to develop a score capturing a continuum from normal graft function to nonfunction after transplant. Both parenchymal and vascular factors, which provide an indication to list for retransplant, were included among the EAF determinants. The L-GrAFT kinetic approach was adopted and modified with fewer data entries and novel variables. The population included 1609 patients in Italy for the derivation set and 538 patients in the UK for the validation set; all were patients who underwent transplant in 2016 and 2017. Main Outcomes and Measures: Early allograft failure was defined as graft failure (codified by retransplant or death) for any reason within 90 days after transplant. Results: At day 90 after transplant, the incidence of EAF was 110 of 1609 patients (6.8%) in the derivation set and 41 of 538 patients (7.6%) in the external validation set. Median (interquartile range) ages were 57 (51-62) years in the derivation data set and 56 (49-62) years in the validation data set. The EASE score was developed through 17 entries derived from 8 variables, including the Model for End-stage Liver Disease score, blood transfusion, early thrombosis of hepatic vessels, and kinetic parameters of transaminases, platelet count, and bilirubin. Donor parameters (age, donation after cardiac death, and machine perfusion) were not associated with EAF risk. Results were adjusted for transplant center volume. In receiver operating characteristic curve analyses, the EASE score outperformed L-GrAFT, Model for Early Allograft Function, Early Allograft Dysfunction, Eurotransplant Donor Risk Index, donor age × Model for End-stage Liver Disease, and Donor Risk Index scores, estimating day 90 EAF in 87% (95% CI, 83%-91%) of cases in both the derivation data set and the internal validation data set. Patients could be stratified in 5 classes, with those in the highest class exhibiting unsustainable EAF risk. Conclusions and Relevance: This study found that the developed EASE score reliably estimated EAF risk. Knowledge of contributing factors may help clinicians to mitigate risk factors and guide them through the challenging clinical decision to allocate patients to early liver retransplant. The EASE score may be used in translational research across transplant centers.

RESUMEN

The use of machine perfusion (MP) in liver transplantation (LT) is spreading worldwide. However, its efficacy has not been demonstrated, and its proper clinical use has far to go to be widely implemented. The Società Italiana Trapianti d'Organo (SITO) promoted the development of an evidence-based position paper. A 3-step approach has been adopted to develop this position paper. First, SITO appointed a chair and a cochair who then assembled a working group with specific experience of MP in LT. The Guideline Development Group framed the clinical questions into a patient, intervention, control, and outcome (PICO) format, extracted and analyzed the available literature, ranked the quality of the evidence, and prepared and graded the recommendations. Recommendations were then discussed by all the members of the SITO and were voted on via the Delphi method by an institutional review board. Finally, they were evaluated and scored by a panel of external reviewers. All available literature was analyzed, and its quality was ranked. A total of 18 recommendations regarding the use and the efficacy of ex situ hypothermic and normothermic machine perfusion and sequential normothermic regional perfusion and ex situ MP were prepared and graded according to the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) method. A critical and scientific approach is required for the safe implementation of this new technology.

RESUMEN

BACKGROUND: Hepatic resection represents the best treatment for primary and metastatic liver tumors but is not always feasible. In early 1980, Piclmayr described a complex liver resection technique, termed "ex vivo liver resection," for the treatment of locally advanced tumors not conventionally resectable. The authors approached this technique with translational research in a preclinical setting and then similarly reproduced it in human patients. METHODS: In the swine median xyphopubic laparotomy, the liver was mobilized to expose the vena cava. A temporary porto-caval shunt was previously prepared on the back table using a segment of thoracic aorta, and a vascular anastomosis between the supra-hepatic vena cava and a caval graft was quickly performed. The liver was placed in a machine perfusion system and continuously perfused for 2 h for its final implantation orthotopically in the same animal. The anastomoses were performed as usual. Based on this experience, the intervention was reproduced in the human model of a 39-year-old woman affected by large intrahepatic cholangiocarcinoma considered unresectable.' RESULTS: All animals survived the procedure. The peak aspartate aminotransferase level (460 ± 87 U/L) was recorded 60 min after reperfusion. Lactate levels flared up for 120 min (3.6 ± 0.2 mmol/L). In the clinical case, the postoperative period was uneventful, and the patient was discharged on day 22. CONCLUSIONS: The described procedure is feasible only for surgeons with a transplantation background. The study showed that this translational approach enhances the surgeon's ability to perform the intervention systematically in a shorter time and with a good outcome.

RESUMEN

BACKGROUND: Videolaparoscopic (VL) microwave ablation (MWA) is not included in most of the international guidelines as a therapeutic option for hepatocellular carcinoma (HCC). Aim of this study was to assess the safety of VL MWA in patients with HCC for whom resection or percutaneous ablation is unsuitable. METHODS: A retrospective analysis was performed on a prospective database of patients with HCC treated with VL MWA at our institution from 2009 to 2016. Patient demographics, operational characteristics, and complications were recorded. Statistical analysis was performed to identify safety profile, overall survival and recurrence rate. RESULTS: A total of 815 VL MWA were performed in 674 patients with a mean age of 64 years. Patients had a mean Model for End-stage Liver Disease score of 10 (±3); 32.8% were Child B, 44.1% Barcelona Clinic Liver Cancer B-C. Perioperative mortality was 0.4%. Overall morbidity was 30.8%, with Dindo-Clavien complications ≥3 in 2%. The median length of stay was 2 days. In 43.1% VL MWA was the first-line therapy. Overall 1-, 3-, and 5-year survival rates were 81.9%, 54.9%, and 35.9%. CONCLUSIONS: The present is the largest series of VL ablation and the bigger number of patients with HCC treated with MW reported nowadays. It confirms the safety of a minimally invasive procedure for patients with HCC when resection or percutaneous ablation is not feasible.

RESUMEN

BACKGROUND: Laparoscopic microwave ablation and portal vein ligation for staged hepatectomy (LAPS) is a new technique with a first laparoscopic step available in cases of unresectable right liver masses and inadequate future liver remnant (FLR). METHODS: In Step 1, laparoscopic right portal vein occlusion is performed with microwave ablation on the future transection plane and in the FLR. Step 2 consists of a totally laparoscopic right trisectionectomy. RESULTS: Duration of the Step 1 operation was 170 min, without the need for blood transfusions and intensive care unit admission. The postoperative liver volumetric computed tomography scan was performed on postoperative day 9 and revealed a satisfactory left hepatic hypertrophy (FLR 666 cm(3); FLR to body weight ratio 0.96; FLR increase 90.4 %; daily FLR hypertrophy 35 cm(3)/day). Duration of the Step 2 operation was 630 min (liver transection time 240 min). Blood loss was 700 cc, with no need for transfusion. The specimen was extracted through a 10-cm Pfannenstiel incision, and pathology revealed a tumor-free resection margin (R0). The patient was discharged on postoperative day 7 without complications (total hospital stay for Step 1 + Step 2: 10 days). CONCLUSIONS: Totally LAPS is a technically feasible and safe procedure. It could provide benefit in selected patients with primarily non-resectable liver cancer, making extreme liver surgery easy and safe in well-selected patients.

RESUMEN

Liver transplant is the preferred treatment for hepatocellular carcinoma in patients with cirrhosis, as both neoplastic and cirrhotic liver tissue can be removed. Treatment of recurring neoplasms is a difficult issue, especially in long-term survivors of liver transplant. No consensus has been reached on the treatment of recurrent hepatocellular carcinoma. Although patients with extrahepatic metastases are generally not candidates for local therapy, successful multimodal salvage therapy including resection or ablation can be achieved in liver transplant recipients with local recurrence of hepatocellular carcinoma. Microwave ablation is safe and effective for treating unresectable hepatocellular carcinoma, achieving excellent results in local disease down-staging or as a "bridge" to liver transplant, with no significant differences in local recurrence and complications compared with the more commonly used radiofrequency ablation. A patient with local recurrence of hepatocellular carcinoma 36 months after liver transplant for multifocal hepatocellular carcinoma and cirrhosis due to hepatitis C was successfully treated with laparoscopic microwave ablation without any postoperative complications. The patient is disease free 24 months after microwave ablation.

RESUMEN

The particular anatomic location of the hepatic caudate lobe between the hilar plate and inferior vena cava means that it is still considered unsuitable for laparoscopic measures and a difficult site even for conventional surgery. Here we describe the first case to be reported in the literature of caudate lobe resection for a single metastasis from breast adenocarcinoma that was completed using an exclusively laparoscopic procedure and a simplified scheme involving the placement of 4 trocars, without any need for conversion or the Pringle maneuver. The patient was 31 years old with a history of radical right mastectomy and chemotherapy. The patient's postoperative course was uneventful and she was discharged 4 days after the surgery. Twelve months on, she is currently alive and disease free.

RESUMEN

Antioxidant agents have the potential to reduce ischemia/reperfusion damage to organs for liver transplantation (LT). In this prospective, randomized study, we tested the impact of an infusion of N-acetylcysteine (NAC) during liver procurement on post-LT outcomes. Between December 2006 and July 2009, 140 grafts were transplanted into adult candidates with chronic liver disease who were listed for first LT, and according to a sequential, closed-envelope, single-blinded procedure, these patients were randomly assigned in a 1/1 ratio to an NAC protocol (69 patients) or to the standard protocol without NAC [71 patients (the control group)]. The NAC protocol included a systemic NAC infusion (30 mg/kg) 1 hour before the beginning of liver procurement and a locoregional NAC infusion (300 mg through the portal vein) just before cross-clamping. The primary endpoint was graft survival. The graft survival rates at 3 and 12 months were 93% and 90%, respectively, in the NAC group and 82% and 70%, respectively, in the control group (P = 0.02). An adjusted Cox analysis showed a significant NAC effect on graft survival at both 3 months [hazard ratio = 1.65, 95% confidence interval (CI) = 1.01-2.93, P = 0.04] and 12 months (hazard ratio = 1.73, 95% CI = 1.14-2.76, P ≤ 0.01). The incidence of postoperative complications was lower in the NAC group (23%) versus the control group (51%, P < 0.01). In the subgroup of 61 patients (44%) receiving suboptimal grafts (donor risk index > 1.8), the incidence of primary dysfunction of the liver was lower (P = 0.09) for the NAC group (15%) versus the control group (32%). In conclusion, the NAC harvesting protocol significantly improves graft survival. The effect of NAC on early graft function and survival seems higher when suboptimal grafts are used.

RESUMEN

The use of temporary porto-caval shunt (TPCS) has been shown to improve hemodynamic stability and renal function in patients undergoing orthotopic liver transplantation (OLT). We evaluated the impact of TPCS in OLT and analyzed the differences according to model for end-stage liver disease (MELD), donor risk index (DRI) and D-MELD. This is a retrospective single-center analysis of 148 consecutive OLT. Fifty-eight OLT were performed using TPCS and 90 without TPCS. Donor and recipient data with pre-OLT, intraoperative and postoperative variables were reviewed. Overall graft survival was 89.9% at 3 months and 81.7% at 1 year. Graft survival at 3 months and 1 year was 93.1% and 79.2%, respectively, in TPCS group versus 85.6% and 82.2%, respectively, in non-TPCS group (P = NS). Intraoperative packed red blood cells requirement was lower in TPCS group (7.5 ± 5.8 vs. 12.2 ± 14.2, P = 0.006) and non-TPCS group required higher intraoperative total dose of phenylephrine (16% vs. 28%, P = 0.04). TPCS group had lower 30-day postoperative mortality (1.7% vs. 10%, P = 0.04), no difference was observed at 90 days. Graft survival was lower in patients with high DRI; in this group graft loss was higher at 1 month (25% vs. 4.3%, P = 0.005) and 3 months (25% vs. 4.3%, P = 0.005) when TPCS was not used. TPCS improves perioperative outcome, this being more evident when high-risk grafts are placed into high-risk patients.

RESUMEN

BACKGROUND & AIMS: Recurrence of hepatocellular cancer after resection is a significant problem. The optimal treatment of patients with intrahepatic recurrence after resection and well-preserved liver function is not clear. We analyzed the outcomes of patients undergoing a second hepatic resection for recurrent hepatocellular cancer at a single Western center. METHODS: The records of all patients undergoing primary hepatic resection for hepatocellular cancer between January 1994 and January 2009 were reviewed. Patients with a single intrahepatic recurrence, Child's A liver function, and platelet count>100,000/µl underwent a second hepatic resection. Clinical data was recorded and analyzed. RESULTS: Of the 487 patients undergoing primary resection, 221 developed recurrence, and 35 underwent a second hepatic resection. There were no perioperative mortalities. There were 10 deaths during the study period; 5-year overall survival was 67% from second resection. Time to recurrence from primary resection<1 year and gross vascular invasion at second resection were predictors of survival and recurrence. Patients with recurrence>1 year from primary resection and without gross vascular invasion had a 5-year survival of 81%. There were 17 recurrences with a 3-year recurrence rate of 55%. CONCLUSIONS: Second hepatic resection for recurrent hepatocellular cancer is applicable in about 15% of patient with recurrence. The procedure is safe and can achieve excellent results in well-selected patients. Recurrence continues to be a significant problem.
