RESUMEN
BACKGROUND: Full-right/full-left liver splitting was introduced early in the 90s as part of the great wave of technical innovations that characterized that decade. One approach was to divide the liver on the right of the Cantlie's line and leave the middle hepatic vein with the left graft, with both grafts allocated to adults. Both grafts had some functional disadvantages and exposed the adult recipients to some early hepatic dysfunction, and the results were not great. An alternative approach consisted of an ex situ division of the liver, exactly along Cantlie's line, thus sharing the middle hepatic vein between the two grafts. None of these two techniques were really adopted, and there has been nearly no transplantation of this type in the last decade worldwide. METHOD AND RESULTS: The authors propose a variation of the latter technique that was used recently with success: The division of the liver is made simpler; the two grafts are prepared ex situ and need a simple vascular reconstruction (one venous patch on each graft); and the grafts can be implanted using very standard techniques. CONCLUSION: Because candidates for liver transplantation weighing 25-60 kg (old children, teenagers, and some small adults) are often at some disadvantage in getting size-matched livers (this range of weight is less represented in the donor population), implementing the latter technique would help provide adequate grafts for them. In Italy, where many livers offered for splitting are not used, there would be ample room for implementing this option within the actual donor pool and allocation system.

BACKGROUND: Ischemia/reperfusion injury (IRI), acute rejection (AR), and delayed graft function (DGF) might occur as major complications following kidney transplantation. Thus, the identification of biomarkers for the IRI, AR, and/or DGF development becomes crucial as it may help to guide post-transplant management. Natural killer (NK) cells, hepatic interstitial T-lymphocytes (T-Li), and NK-T cells are crucial in both innate and adaptive immunity after abdominal solid organ transplantation. Hence, the aim of this study was to evaluate the impact of the immune system after graft reperfusion during KT in adults in order to identify predictive biomarkers. METHODS: The NK, T-Li, and NK-T phenotypes and concentrations were retrospectively analyzed in a consecutive series of liver perfusates obtained after organ procurement flushing the abdominal cavity recovered from deceased brain donors (DBDs). Their percentage was compared with the renal transplant recipients' characteristics with kidneys taken from the same DCDs. The hepatic perfusate cells were purified by density gradient centrifugation. Flow cytometric investigation was used to determine their phenotype with the following immunological markers in order to determine the relative percentage of T-Li, NK-T, and NK cells: CD3, CD4, CD8, and CD56. RESULTS: 42 DBDs' liver perfusates were analyzed. The related clinical outcomes of kidney transplant recipients from 2010 to 2020 performed at our Institute were evaluated. Time in days of delayed functional recovery of transplanted kidneys (DGF) (p = 0.02) and the onset of secondary infection from a cytomegalovirus (p = 0.03) were significantly associated with the T-Li percentage. An increased relative risk (HR) of organ survival was significantly associated with the percent cell concentration of T-Li and time to DGF, on COX analysis, were (HR = 1.038, p = 0.04; and HR = 1.029, p = 0.01, respectively). None relevant clinical outcomes in kidney transplant patients were associated with the specificity of the NK and NK-T cell proportions. CONCLUSIONS: A new potential role of T-Li cells was detected in the context of hepatic perfusate from DBDs. It could detect potential impacts in organ allocation, surgical procuring techniques, and in the analysis of IRI pathophysiological events.
RESUMEN
The match between donor and recipient (D-R match) in the field of liver transplantation (LT) is one of the most widely debated topics today. Within the cohort of patients waiting for a transplant, better matching of the donor organ to the recipient will improve transplant outcomes, and benefit the waiting list by minimizing graft failure and the need for re-transplantation. In an era of suboptimal matches due to the sparse organ pool and the increase in extended criteria donors (ECD), ensuring adequate outcomes becomes the primary goal for clinicians in the field. The objective of this mini-review is to analyze the main variables in the evaluation of the D-R match to ensure better outcomes, the existence of scores that can help in the realization of this match, and the latest advances made thanks to the technology and development of artificial intelligence (AI).

Introduction: Hepatocellular carcinoma (HCC) accounts for nearly 90% of primary liver cancers, with estimates of over 1 million people affected by 2025. We aimed to explore the impacting role of an iterative surgical treatment approach in a cohort of HCC patients within the Milan criteria, associated with clinical risk factors for tumor recurrence (RHCC) after liver transplant (LT) and loco-regional therapies (LRT), as well as liver resection (LR) and/or microwave thermal ablation (MWTA). Methods: We retrospectively analyzed our experience performed during an 8-year period between January 2013 and December 2021 in patients treated for HCC, focusing on describing the impact on preoperative end-stage liver disease severity, oncologic staging, tumor characteristics, and surgical treatments. The Cox model was used to evaluate variables that could predict relapse risks. Relapse risk curves were calculated according to the Kaplan-Meier method, and the log-rank test was used to compare them. Results: There were 557 HCC patients treated with a first-line approach of LR and/or LRTs (n = 335) or LT (n = 222). The median age at initial transplantation was 59 versus 68 for those whose first surgical approach was LR and/or LRT. In univariate analysis with the Cox model, nodule size was the single predictor of recurrence of HCC in the posttreatment setting (HR: 1.61, 95% CI: 1.05-2.47, p = 0.030). For the LRT group, we have enlightened the following clinical characteristics as significantly associated with RHCC: hepatitis B virus infection (which has a protective role with HR: 0.34, 95% CI: 0.13-0.94, p = 0.038), number of HCC nodules (HR: 1.54, 95% CI: 1.22-1.94, p < 0.001), size of the largest nodule (HR: 1.06, 95% CI: 1.01-1.12, p = 0.023), serum bilirubin (HR: 1.57, 95% CI: 1.03-2.40, p = 0.038), and international normalized ratio (HR: 16.40, 95% CI: 2.30-118.0, p = 0.006). Among the overall 111 patients with RHCC in the LRT group, 33 were iteratively treated with further curative treatment (12 were treated with LR, two with MWTA, three with a combined LR-MWTA treatment, and 16 underwent LT). Only one of 18 recurrent patients previously treated with LT underwent LR. For these RHCC patients, multivariable analysis showed the protective roles of LT for primary RHCC after IDLS (HR: 0.06, 95% CI: 0.01-0.36, p = 0.002), of the time relapsed between the first and second IDLS treatments (HR: 0.97, 95% CI: 0.94-0.99, p = 0.044), and the impact of previous minimally invasive treatment (HR: 0.28, 95% CI: 0.08-1.00, p = 0.051). Conclusion: The coexistence of RHCC with underlying cirrhosis increases the complexity of assessing the net health benefit of ILDS before LT. Minimally invasive surgical therapies and time to HCC relapse should be considered an outcome in randomized clinical trials because they have a relevant impact on tumor-free survival.
RESUMEN
BACKGROUND: The current curative approaches for ischemia/reperfusion injury on liver transplantation are still under debate for their safety and efficacy in patients with end-stage liver disease. We present the SIMVA statin donor treatment before Liver Transplants study. METHODS: SIMVA statin donor treatment before Liver Transplants is a monocentric, double-blind, randomized, prospective tial aiming to compare the safety and efficacy of preoperative brain-dead donors' treatment with the intragastric administration of 80 mg of simvastatin on liver transplant recipient outcomes in a real-life setting. Primary aim was incidence of patient and graft survival at 90 and 180 d posttransplant; secondary end-points were severe complications. RESULTS: The trial enrolled 58 adult patients (18-65 y old). The minimum follow-up was 6 mo. No patient or graft was lost at 90 or 180 d in the experimental group (n = 28), whereas patient/graft survival were 93.1% ( P = 0.016) and 89.66% ( P = 0.080) at 90 d and 86.21% ( P = 0.041) and 86.2% ( P = 0.041) at 180 d in the control group (n = 29). The percentage of patients with severe complications (Clavien-Dindo ≥IIIb) was higher in the control group, 55.2% versus 25.0% in the experimental group ( P = 0.0307). The only significant difference in liver tests was a significantly higher gamma-glutamyl transferase and alkaline phosphatase at 15 d ( P = 0.017), ( P = 0.015) in the simvastatin group. CONCLUSIONS: Donor simvastatin treatment is safe, and may significantly improve early graft and patient survival after liver transplantation, although further research is mandatory.

BACKGROUND: liver lateral section graft is the most common graft type used for transplantation in children worldwide. Compared to whole liver grafts, a higher rate of biliary complications has been described. Historically, 2 techniques have been described for transection of liver - trans-hilar or trans-umbilical parenchymal transection. Though these techniques allow dividing the biliary system at two distinct positions, the usual surgical strategies do not take advantage of this advantage. MATERIAL AND METHODS: A retrospective study was conducted on 40 candidates who volunteered for donation of their left lateral liver section for transplantation, between October 2017 and April 2019. Preoperative imaging was analyzed to depict the arterial and biliary anatomy of the liver and their variations, with a dedicated attention to the left liver (segments 2, 3 and 4). Anatomy of the biliary system was taken into account for defining the optimal surgical strategy - either through a trans-hilar or a trans-umbilical parenchymal transection. RESULTS: In 26/40 patients, arterial or biliary variations were much relevant for decision-making on the optimal plane of liver division (trans-umbilical (N = 14) and trans-hilar (N = 26)). This resulted in 23 grafts with a single artery and bile duct, 6 grafts with double arteries and a single bile duct, and 9 grafts with double bile ducts and a single artery; only two grafts had complex anatomy. There was no arterial complication and the overall incidence of biliary problems was 14.7%. All grafts are functioning well at a mean follow-up of 19.6 ± 8.5 months. CONCLUSIONS: Anatomical variations are frequent and their knowledge is relevant for procurement of lateral section liver graft. Knowledge of these variation, or -better- preoperative biliary imaging is helpful in guiding parenchymal transection at procurement and preparing optimal liver grafts.

BACKGROUND: One of the major issues related to the living donor liver transplantation recipient outcome is still the high rate of biliary complication, especially when multiple biliary ducts are present and multiple anastomoses have to be performed. CASE PRESENTATION AND CONCLUSION: We report a case of adult-to-adult right lobe living donor liver transplantation performed for a recipient affected by alcohol-related cirrhosis with MELD score of 17. End-stage liver disease was complicated by refractory ascites, portal hypertension, small esophageal varices and portal gastropathy, hypersplenism, and abundant right pleural effusion. Here in the attached video we described the adult-to-adult LDLT procedures, where a right lobe with two biliary ducts draining respectively the right anterior and the right posterior segments has been transplanted. LDLT required a biliary reconstruction using the native cystic and common bile ducts stented trans-papillary with two 5- French 6 cm long soft silastic catheter. None major complications were detected during post-operative clinical courses. Actually, the donor and the recipient are alive and well. The technique we describe in the video, allow to keep the biliary anastomoses protected and patent without having the risk of creating cholestasis and the need of invasive additional procedure. No living donor right lobe transplantation should be refused because of the presence of multiple biliary ducts.

Background: Laparoscopic microwave thermal ablation (LMWTA) is a well-established alternative treatment to liver resection for treatment of liver tumors. The aim of this study was to describe our experience in LMWTA for hepatocellular carcinoma (HCC) in chronic hepatic patients. Materials and Methods: A study group of 61 consecutive HCC patients treated with LMWTA from January, 2013 to May, 2020 were considered for this study. Patient characteristics, liver function test, operational characteristics, and complications were recorded. Results: Of the 61 patients who underwent LMWTA, median age was 64 (interquartile range [IQR]: 58-71) years, mean body mass index was 26.2 (IQR: 23.2-29.4); 44 patients (72%) presented with an hepatitis C virus etiology, 46 (75%) were Child-Pugh Class A, median model for end-stage liver disease (MELD) score was 8.0 (IQR: 7.0-9.4). Viral infection was confirmed to be the most important risk factor in determining progressive cirrhotic evolution with HCC expression. Conclusions: LMWTA is a safe alternative treatment to traditional surgery, and can be combined with surgery.

BACKGROUND: Liver transplantation (LT) is the only definitive and curative treatment for patients with end-stage liver disease and hepatocellular carcinoma. We aimed to evaluate the impact of the Italian score for organ allocation (ISO) in terms of the waiting-list mortality, probability of LT, and patient survival after LT. PATIENT AND METHODS: All of the adult patients on the waiting list for LT at our institute from January 2014 to December 2017 were included in the study. The probabilities of death while on the waiting list, dropout from the list, and LT were compared by means of cumulative incidence functions, in a competing risk time-to-event analysis setting. Uni- and multivariable logistic regression models were used to estimate and compare the probability of death and to find potential risk factors for waiting-list death. RESULTS: There were 286 patients on the waiting list for LT during the study period, 122 of whom entered the waiting list prior to the implementation of ISO (Group A) and 164 afterward (Group B). Group A had 62 transplants, and Group B had 116 transplants. Group B showed a lesser probability of death (P = .005) and a greater probability of transplant (P < .001) compared to Group A. In the 2 groups, post-transplant survival was similar. CONCLUSION: Based on preliminary clinical experience from a single transplant center, the ISO allocation system demonstrated an overall reduced probability of patient death while on the waiting list without impairing post-LT survival, suggesting that the ISO system might represent an improved method of organ allocation, with a more beneficial distribution of livers.

INTRODUCTION: Laparoscopic living donor nephrectomy (LLDN) has become the standard procedure for living kidney transplantation. Enhanced recovery after surgery (ERAS) is a multimodal perioperative management aimed at facilitating rapid patient recovery after major surgery by modifying the response to stress induced by exposure to surgery. This association can further reduce hospital stay, surgical stress, and perioperative morbidity of living kidney donors. MATERIAL AND METHODS: In this retrospective analysis conducted at our institute, we compared the first 21 patients who underwent LLDN enrolled with the ERAS protocol with 55 patients who underwent LLDN with the fast-track protocol in the 5 years prior to ERAS protocol implementation. RESULTS: We evaluated 76 consecutive patients. After ERAS protocol implementation, elderly living donors had a shorter hospital stay and a faster return to normal life compared with the same age group of patients in the previous period. There were no major differences in median postoperative hospital stay and no meaningful differences in the percentage of complications after surgery and hospital readmissions. CONCLUSIONS: The introduction of the ERAS protocol for patients undergoing LLDN compared with the traditional protocol led to a reduction in postoperative hospitalization in elder donors, without determining a raise in the number of hospital complications and readmissions.

BACKGROUND: The gap between organ availability and patients on the waiting list for deceased donor kidney transplants has resulted in the wide use of extended criteria donors (ECDs).We aimed to compare the surgical outcomes of single kidney transplantation (KT) performed at our institute with standard criteria donor (SCD) or ECD grafts, according to the Organ Procurement and Transplantation Network definition. PATIENTS AND METHODS: Our retrospective analysis studied 115 adult recipients of KT from January 2016 to July 2018, with kidney grafts procured from adult donors after brain or circulatory death, performed at our institute. Among the 2 recipients' groups, we compared the incidence of early graft loss, delayed graft function, hospitalization, and surgical complications. We compared the evaluation of time to early graft loss with Kaplan-Meier estimators and curves; the hypothesis of no difference in time to graft loss between the 2 groups was tested using the log-rank statistics. RESULTS: Of the 103 deceased donor kidney transplants during the study period, 129 grafts were used after the regional network sharing allocation. More frequently, ECDs had a greater body mass index than SCDs (25.2 ± 3.9 vs 27.7 ± 5.0, P = .005) and type II diabetes mellitus (0% vs 18%, P = .002). KT recipients who received an ECD graft (73, 63.5%) were older (59.8 ± 9.8 vs 45.2 ± 15.4, P < .001) and presented a higher rate of delayed graft function (56% vs 24%, P = .001). Post-transplant graft loss did not differ among the 2 groups. CONCLUSION: Based on clinical experience in a single transplant center, ECD use for KTs is crucial in facing the organ shortage, without impairing post-deceased donor kidney transplant outcomes.

BACKGROUND: Liver transplantation is the best treatment for end-stage liver disease. The interruption of the blood supply to the donor liver during cold storage damages the liver, affecting how well the liver will function after transplant. The drug Simvastatin may help to protect donor livers against this damage and improve outcomes for transplant recipients. The aim of this study is to evaluate the benefits of treating the donor liver with Simvastatin compared with the standard transplant procedure. PATIENT AND METHODS: We propose a prospective, double-blinded, randomized phase 2 study of 2 parallel groups of eligible adult patients. We will compare 3-month, 6-month, and 12-month graft survival after LT, in order to identify a significant relation between the two homogenous groups of LT patients. The two groups only differ by the Simvastatin or placebo administration regimen while following the same procedure, with identical surgical instruments, and medical and nursing skilled staff. To reach these goals, we determined that we needed to recruit 106 patients. This sample size achieves 90% power to detect a difference of 14.6% between the two groups survival using a one-sided binomial test. DISCUSSION: This trial is designed to confirm the effectiveness of Simvastatin to protect healthy and steatotic livers undergoing cold storage and warm reperfusion before transplantation and to evaluate if the addition of Simvastatin translates into improved graft outcomes. TRIAL REGISTRATION: ISRCTN27083228 .

INTRODUCTION: Laparoscopic rectal surgery seems to improve postoperative recovery of patients who undergo surgery for rectal cancer. The aim of this study was to evaluate preliminary results of implementation of enhanced recovery after surgery (ERAS) protocol for laparoscopic rectal resection (LRR) for cancer at our institute. MATERIALS AND METHODS: We conducted a retrospective analysis of prospectively collected data. Patients who underwent LRR for cancer at our institute after introduction of enhanced recovery protocol were compared with a control group of patients who previously underwent surgery with traditional protocol. Primary endpoints evaluated were length of stay (LOS) and rates of complications and readmissions. RESULTS: We studied 150 consecutive patients, 56 operated with the traditional approach and 94 according to ERAS protocol. The mean (range) LOS was 10 (4-27) days for patients in control group versus 8.5 (3-32) days for patients in the ERAS group (P = .0823). No evidence of a different rate (P = .227) of complications was registered between the two groups. One patient in each group was readmitted. CONCLUSIONS: The introduction of the ERAS protocol in LRR for cancer at our institute led to an initial reduction in hospital LOS, without increase in morbidity or readmission rate compared with our previous experience with traditional protocol.

BACKGROUND: Renal transplantation is the most successful therapy for improving survival and quality of life for end-stage renal disease (ESRD). Living donor kidney transplantation (LDKTx) has been used as an alternative to reduce the stay on the waiting list of patients with ESRD. Laparoscopic donor nephrectomy (LDN) has become the standard procedure for LDKTx. OBJECTIVE: This study aims to describe evolution of surgical technique with LDN at our institute. MATERIALS AND METHODS: We retrospectively analyzed our experience with LDN performed from January, 2003 to November, 2016, focusing on describing modifications of the surgical technique and devices made during those years. Demographics, operative factors, and postoperative complications of donors were reviewed. RESULTS: From the beginning of our experience with LDKTx we have performed 185 cases. From 2003 to 2016, 144 LDN were performed. Modifying our technique in response to the learning curve, complications encountered, and technological advancements, we experienced low complication rates. CONCLUSIONS: Continual refinement with LDN techniques based on intraoperative observations and technological advances is necessary to keep complication rates low and reduce donor morbidity and time for recovery.

BACKGROUND: The surgical therapy of choice for hepatocellular carcinoma (HCC) is liver transplantation (LT) or hepatic resection, although only a small percentage of patients can undergo these procedures. Microwave thermal ablation (MWTA) can be an effective alternative treatment for HCC that complicates a cirrhotic liver disease, either as a final procedure or for downstaging patients on the waiting list for LT, or in combination with resective surgery to achieve oncological radicality. OBJECTIVE: The purpose of this retrospective study was to evaluate experience with the laparoscopic approach of MWTA at our center. MATERIALS AND METHODS: In a cohort of 35 consecutive patients undergoing MWTA with laparoscopic approach between January, 2013 and May, 2016, we reviewed the demographic data, the Barcelona clinic liver cancer stage, the severity of cirrhotic liver disease, the size of the ablated lesion, the duration of the procedure, and complications occurring within 90 days of surgery. RESULTS: MWTA was performed by applying one to three hepatic parenchymal insertions (mean 1.8) per patient. The mean duration of surgery was 163 ± 18 minutes. There was no blood loss in any of the procedures. Complete necrosis on CT scan was achieved in 26/35 patients (75%). The mean hospital stay was 4.6 (range 2-7) days; major complications were postablation syndrome in 2/35 (5.7%), peritoneal fluid in 4/35 (11.4%), and transient jaundice in 1/35 (2.8%) patients. There was no mortality. CONCLUSIONS: Laparoscopic MTWA is a safe and effective treatment for unresectable HCC and when a percutaneous procedure is not feasible.

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.

AIM: VEGF and AFP mRNA determinations in the blood are promising prognostic factors for patients with HCC. This study explores their potential prognostic synergy in a cohort of HCC patients evaluated for potentially curative therapies. METHODS: One hundred twenty-four patients with a diagnosis of HCC were prospectively enrolled in the study. Inclusion criteria were: (a) histological diagnosis of HCC and assessment of tumour grade and (b) determination of AFP mRNA status and VEGF levels in the blood before therapy. RESULTS: At baseline evaluation, 40% of the study group had AFP mRNA in the blood (AFP mRNA positive), and 35% had VEGF>23 pg ml(-1) (VEGF positive). Surgery was performed in 58 patients (47%), 54 (43%) had tumour ablation, and 12 had chemoembolisation (10%). Median follow-up and survival of the study group were 19 and 26 months (range, 1 to 60), respectively. The association of AFP mRNA and VEGF proved to be prognostically more accurate than their single use in discriminating the risk of death (ROC curve analysis) and survival probability (Cox analysis). In particular, we identified 3 main molecular stages (p<0.0001): both negative (3-year survivalâ=â63%), one positive (3-year survivalâ=â40%), both positive (3-year survivalâ=â16%). Multivariate analysis identified BCLC staging, surgery, and molecular staging as the most significant survival variables. CONCLUSIONS: The preoperative determination of AFP mRNA status and VEGF may potentially refine the prognostic evaluation of HCC patients and improve the selection process for potentially curative therapies.

This work is the first report of vacuum-assisted closure (VAC) therapy applied as a life-saving surgical treatment for severe acute pancreatitis occurring in a sequential liver- and kidney-transplanted patient who had percutaneous biliary drainage for obstructive "late-onset" jaundice. Surgical exploration with necrosectomy and sequential laparotomies was performed because of increasing intra-abdominal pressure with hemodynamic instability and intra-abdominal multidrug-resistant sepsis, with increasingly difficult abdominal closure. Repeated laparotomies with VAC therapy (applying a continuous negative abdominal pressure) enabled a progressive, successful abdominal decompression, with the clearance of infection and definitive abdominal wound closure. The application of a negative pressure is a novel approach to severe abdominal sepsis and laparostomy management with a view to preventing compartment syndrome and fatal sepsis, and it can lead to complete abdominal wound closure.
