The widespread uptake of different machine perfusion(MP)strategies for liver transplant has been driven by an effort to minimize graft injury.Damage to the cholangiocytes during the liver donation,preservation,or early posttransplant period may result in stricturing of the biliary tree and inadequate biliary drainage.This problem continues to trouble clinicians,and may have catastrophic consequences for the graft and patient.Ischemic injury,as a result of compromised hepatic artery flow,is a well-known cause of biliary strictures,sepsis,and graft failure.However,very similar lesions can appear with a patent hepatic artery and these are known as ischemic type biliary lesions(ITBL)that are attributed to microcirculatory dysfunction rather than main hepatic arterial compromise.Both the warm and cold ischemic period duration appear to influence the onset of ITBL.All of the commonly used MP techniques deliver oxygen to the graft cells,and therefore may minimize the cholangiocyte injury and subsequently reduce the incidence of ITBL.As clinical experience and published evidence grows for these modalities,the impact they have on ITBL rates is important to consider.In this review,the evidence for the three commonly used MP strategies(abdominal normothermic regional perfusion[A-NRP],hypothermic oxygenated perfusion[HOPE],and normothermic machine perfusion[NMP])for ITBL prevention has been critically reviewed.Inconsistencies with ITBL definitions used in trials,coupled with variations in techniques of MP,make interpretation challenging.Overall,the evidence suggests that both HOPE and A-NRP prevent ITBL in donated after circulatory death grafts compared to cold storage.The evidence for ITBL prevention in donor after brain death grafts with any MP technique is weak. 展开更多

BACKGROUND Liver resection is the mainstay for a curative treatment for patients with resectable hepatocellular carcinoma(HCC),also in elderly population.Despite this,the evaluation of patient condition,liver function and extent of disease remains a demanding process with the aim to reduce postoperative morbidity and mortality.AIM To identify new perioperative risk factors that could be associated with higher 90-and 180-d mortality in elderly patients eligible for liver resection for HCC considering traditional perioperative risk scores and to develop a risk score.METHODS A multicentric,retrospective study was performed by reviewing the medical records of patients aged 70 years or older who electively underwent liver resection for HCC;several independent variables correlated with death from all causes at 90 and 180 d were studied.The coefficients of Cox regression proportional-hazards model for sixmonth mortality were rounded to the nearest integer to assign risk factors'weights and derive the scoring algorithm.RESULTS Multivariate analysis found variables(American Society of Anesthesiology score,high rate of comorbidities,Mayo end stage liver disease score and size of biggest lesion)that had independent correlations with increased 90-and 180-d mortality.A clinical risk score was developed with survival profiles.CONCLUSION This score can aid in stratifying this population in order to assess who can benefit from surgical treatment in terms of postoperative mortality. 展开更多

BACKGROUND Surgical resection and radiofrequency ablation(RFA)represent two possible strategy in treatment of hepatocellular carcinoma(HCC)in Milan criteria.AIM To evaluate short-and long-term outcome in elderly patients(>70 years)with HCC in Milan criteria,which underwent liver resection(LR)or RFA.METHODS The study included 594 patients with HCC in Milan criteria(429 in LR group and 165 in RFA group)managed in 10 European centers.Statistical analysis was performed using the Kaplan-Meier method before and after propensity score matching(PSM)and Cox regression.RESULTS After PSM,we compared 136 patients in the LR group with 136 patients in the RFA group.Overall survival at 1,3,and 5 years was 91%,80%,and 76%in the LR group and 97%,67%,and 41%in the RFA group respectively(P=0.001).Diseasefree survival at 1,3,and 5 years was 84%,60%and 44%for the LR group,and 63%,36%,and 25%for the RFA group(P=0.001).Postoperative Clavien-Dindo IIIIV complications were lower in the RFA group(1%vs 11%,P=0.001)in association with a shorter length of stay(2 d vs 7 d,P=0.001).In multivariate analysis,Model for End-stage Liver Disease(MELD)score(>10)[odds ratio(OR)=1.89],increased value of international normalized ratio(>1.3)(OR=1.60),treatment with radiofrequency(OR=1.46),and multiple nodules(OR=1.19)were independent predictors of a poor overall survival while a high MELD score(>10)(OR=1.51)and radiofrequency(OR=1.37)were independent factors associated with a higher recurrence rate.CONCLUSION Despite a longer length of stay and a higher rate of severe postoperative complications,surgery provided better results in long-term oncological outcomes as compared to ablation in elderly patients(>70 years)with HCC in Milan criteria. 展开更多

BACKGROUND Liver surgery has traditionally been characterized by the complexity of its procedures and potentially high rates of morbidity and mortality in inexperienced hands.The robotic approach has gradually been introduced in liver surgery and has increased notably in recent years.However,few centers currently perform robotic liver surgery and experiences in robot-assisted surgical procedures continue to be limited compared to the laparoscopic approach.AIM To analyze the outcomes and feasibility of an initial robotic liver program implemented in an experienced laparoscopic hepatobiliary center.METHODS A total of forty consecutive patients underwent robotic liver resection(da Vinci Xi,intuitive.com,United States)between June 2019 and January 2021.Patients were prospectively followed and retrospectively reviewed.Clinicopathological characteristics and perioperative and short-term outcomes were analyzed.Data are expressed as mean and standard deviation.The study was approved by the Institutional Review Board.RESULTS The mean age of patients was 59.55 years,of which 18(45%)were female.The mean body mass index was 29.41 kg/m^(2).Nine patients(22.5%)were cirrhotic.Patients were divided by type of resection as follows:Ten segmentectomies,three wedge resections,ten left lateral sectionectomies,six bisegmentectomies(two VVI bisegmentectomies and four IVb-V bisegmentectomies),two right anterior sectionectomies,five left hepatectomies and two right hepatectomies.Malignant lesions occurred in twenty-nine(72.5%)of the patients.The mean operative time was 258.11 min and two patients were transfused intraoperatively(5%).Inflow occlusion was used in thirty cases(75%)and the mean total clamping time was 32.62 min.There was a single conversion due to uncontrollable hemorrhage.Major postoperative complications(Clavien–Dindo>Ⅲb)occurred in three patients(7.5%)and mortality in one(2.5%).No patient required readmission to the hospital.The mean hospital stay was 5.6 d.CONCLUSION Although robotic hepatectomy is a safe and feasible procedure with favorable short-term outcomes,it involves a demanding learning curve that requires a high level of training,skill and dexterity. 展开更多

BACKGROUND Liver resection and radiofrequency ablation are considered curative options for hepatocellular carcinoma.The choice between these techniques is still controversial especially in cases of hepatocellular carcinoma affecting posterosuperior segments in elderly patients.AIM To compare post-operative outcomes between liver resection and radiofrequency ablation in elderly with single hepatocellular carcinoma located in posterosuperior segments.METHODS A retrospective multicentric study was performed enrolling 77 patients age≥70-years-old with single hepatocellular carcinoma(≤30 mm),located in posterosuperior segments(4a,7,8).Patients were divided into liver resection and radiofrequency ablation groups and preoperative,peri-operative and long-term outcomes were retrospectively analyzed and compared using a 1:1 propensity score matching.RESULTS After propensity score matching,twenty-six patients were included in each group.Operative time and overall postoperative complications were higher in the resection group compared to the ablation group(165 min vs 20 min,P<0.01;54%vs 19%P=0.02 respectively).A median hospital stay was significantly longer in the resection group than in the ablation group(7.5 d vs 3 d,P<0.01).Ninety-day mortality was comparable between the two groups.There were no significant differences between resection and ablation group in terms of overall survival and disease free survival at 1,3,and 5 years.CONCLUSION Radiofrequency ablation in posterosuperior segments in elderly is safe and feasible and ensures a short hospital stay,better quality of life and does not modify the overall and disease-free survival. 展开更多

BACKGROUND Few series have reported the utility of fast-track protocols(FTP)in minimally invasive liver surgery.AIM To report the applicability of FTP in minimally invasive liver surgery and to correlate with difficulty scores.METHODS The series of patients undergoing minimally invasive liver surgery from 2014 was analyzed.Iwate,Southampton and Gayet’s scores were compared as predictors of FTP adherence.Accomplishment of FTP was considered within 24-h,48-h and 72-h.Multivariate models were performed to define discharge<24 h,<72 h,complications and readmissions.RESULTS From 160 cases,78 were candidates for FTP,of which 22(28.2%),19(24.4%)and 14(17.9%)were discharged in<24-h,48-h and 72-h,respectively(total=71.5%).Iwate,Southampton and Gayet’s scores achieved area under the receiver operating characteristic values for<24-h stay of 0.780,0.687 and 0.698,respectively.Sensitivity and specificity values for the best score(Iwate)were 87.7%and 66.7%,respectively(cutoff=5.5).In multivariate models,<72 h stay and complications revealed body mass index as a risk factor independent from difficulty scores.CONCLUSION The development of aggressive FTP is feasible and<24-h stay can be achieved even in moderate and advanced complexity cases.Difficulty scores,including body mass index value,may be useful to predict which cases may adhere to these protocols. 展开更多

To describe the main aspects of back-table surgery in pancreatic graft and the problems arising from poor technique.Back-table surgery for pancreatic graft is a complex,meticulous and laborious technique on which the success of implant surgery and perioperative results depends.The technique can be described in the following steps:Preparation of the sterile table,ex-situ inspection of the pancreasspleen block,management of the duodenum,identification of the bile duct,preparation of the portal vein,preparation of the own graft arteries and anastomosis to the arterial graft,spleen management and graft preservation prior to implantation in the recipient.A careful inspection of the pancreas-spleen block should be performed.It is important to identify the stump of the main bile duct,the portal vein cuff,and the arrangement of the superior mesenteric artery and splenic artery.The redundant duodenum must be removed.The availability of a good venous cuff facilitates the portal vein anastomosis and the positioning of the graft,two key points to prevent thrombosis.The section line of the arteries must be clean,without atherosclerosis,to prevent arterial thrombosis.The superior and splenic mesenteric arteries are generally separated by dense fibrolymphatic tissue.The artery can be reconstructed by interposing a"Y"graft from the donor iliac artery;or with an end-to-end anastomosis between the splenic artery and the superior mesenteric artery.An exquisite technique of bench work helps to prevent the most feared complications of pancreas transplantation:Thrombosis and graft pancreatitis. 展开更多
