BACKGROUND: In 2011, a pilot program for deceased organ donation was initiated in China. We describe the first successful series of liver transplants in the pilot program.METHODS: From July 2011 to August 2012, our center performed 26 liver transplants from a pool of 29 deceased donors. All organ donation and allograft procurement were conducted according to the national protocol. The clinical data of donors and recipients were collected and summarized retrospectively.RESULTS: Among the 29 donors, 24 were China Category II donors(organ donation after cardiac death), and five were China Category III donors(organ donation after brain death followed by cardiac death). The recipients were mainly the patients with hepatocellular carcinoma. The one-year patient survival rate was 80.8% with a median follow-up of 422(2-696) days. Among the five mortalities during the follow-up,three died of tumor recurrence. In terms of post-transplant complications, 9 recipients(34.6%) experienced early allograft dysfunction, 1(3.8%) had non-anastomotic biliary stricture,and 1(3.8%) was complicated with hepatic arterial thrombosis.None of these complications resulted in patient death. Notably,primary non-function was not observed in any of the grafts.CONCLUSION: With careful donor selection, liver transplant from deceased donors can be performed safely and plays acritical role in overcoming the extreme organ shortage in China. 展开更多

Background:Over the past two decades robotic surgery has been introduced to many areas including liver surgery.Laparoscopic liver surgery is an alternative minimally invasive approach.However,moving on to the complexity of living donor hepatectomies,the advantages of robotic versus laparoscopic approach have convinced us to establish the robotic platform as a standard for living donor hepatectomy.Methods:From November 2018 to January 2022,501 fully robotic donor hepatectomies,including 177 left lateral donor lobes,112 full left lobes and 212 full right lobes were performed.Grafts were donated to 296 adult recipients and 205 pediatric recipients.Donor age,sex,body weight,body mass index(BMI),graft weight,graft to body weight ratio(GBWR),operative time,blood loss,first warm ischemic time,pain score,length of intensive care unit(ICU)stay and hospital stay,and complications were retrospectively analyzed based on a prospectively kept database.Recipients were evaluated for graft and patient survival,age,sex,BMI,body weight,model of end-stage liver disease score,blood loss,transfusions,operative time,cold ischemic time,length of hospital stay and complications.Results:There was no donor mortality.Two cases needed to be converted to open surgery.The median blood loss was 60 mL(range 20-800),median donor operative time was 6.77 h(range 2.93-11.53),median length of hospital stay was 4 days(range 2-22).Complication rate in donors classified following ClavienDindo was 6.4%(n=32)with one grade Ⅲ complication.Three-year actual recipient overall survival was 91.4%;87.5% for adult recipients and 97.1% for pediatric recipients.Three-year actual graft overall survival was 90.6%;87.5% for adult recipients and 95.1% for pediatric recipients.In-hospital mortality was 6%,9.1%(27/296)for adult recipients and 1.4%(3/205)for pediatric recipients.The recipients’morbidity was 19.8%(n=99).Twenty-eight recipients(5.6%)had biliary and 22(4.4%)vascular complications.Six(12.0%)recipients needed to be re-transplanted.Conclusions:With growing experience it is nowadays possible to perform any donor hepatectomy by robotic approach regardless of anatomical variations and graft size.Donor morbidity and quality for life results are encouraging and should motivate other transplant centers with interest in minimally invasive donor surgery to adopt this robotic technique. 展开更多

BACKGROUND:Marked hemodynamic alteration,commonly referred to as postreperfusion syndrome(PRS),often occurs after revascularization of the donor organ during orthotopic liver transplantation(OLT)and is associated with poor outcomes.This study aimed to investigate the incidence,predictive factors and clinical outcomes of PRS in Chinese patients following OLT at a liver transplantation center in China.METHODS:Over a 5-year period,330 consecutive patients who had undergone OLT for hepatocellular carcinoma or cirrhosis were included in this retrospective study.PRS was defined as a>30%decrease in the mean arterial pressure compared with that before revascularization for more than 1 minute during the first 5 minutes of graft reperfusion.The patients were divided into 2 groups according to the development of PRS:group 1(patients with PRS,n=56)and group 2(patients without PRS,n=274).The demographic characteristics,operative and postoperative courses,and outcomes of the patients were analyzed using SPSS version 18.0.RESULTS:Multivariate regression analysis showed that left ventricular diastolic dysfunction determined by echocardiography and prolonged cold ischemia time were the independent risk factors for PRS.More patients in group 1 showed postoperative renal dysfunction than those in group 2(19.23%vs 8.4%).Moreover,patients in group 1 also had higher intraoperative(7.14%vs 0%)and postoperative mortalities(26.92%vs 12.04%).CONCLUSION:Left ventricular diastolic dysfunction and prolonged cold ischemia time contribute to a high incidence of PRS,which is associated with adverse outcomes in Chinese patients following OLT. 展开更多

Objective:Sex-specific differences are observed in various liver diseases,but the influence of sex on the outcomes of hepatocellular carcinoma(HCC)after liver transplantation(LT)remains to be determined.This study is the first Chinese nationwide investigation of the role of sex in post-LT outcomes in patients with HCC.Methods:Data for recipients with HCC registered in the China Liver Transplant Registry between January 2015 and December 2020 were analyzed.The associations between donor,recipient,or donor-recipient transplant patterns by sex and the post-LT outcomes were studied with propensity score matching(PSM).The survival associated with different sex-based donor-recipient transplant patterns was further studied.Results:Among 3,769 patients enrolled in this study,the 1-,3-,and 5-year overall survival(OS)rates of patients with HCC after LT were 96.1%,86.4%,and 78.5%,respectively,in female recipients,and 95.8%,79.0%,and 70.7%,respectively,in male recipients after PSM(P=0.009).However,the OS was comparable between recipients with female donors and male donors.Multivariate analysis indicated that male recipient sex was a risk factor for post-LT survival(HR=1.381,P=0.046).Among the donor-recipient transplant patterns,the male-male donor-recipient transplant pattern was associated with the poorest post-LT survival(P<0.05).Conclusions:Our findings highlighted that the post-LT outcomes of female recipients were significantly superior to those of male recipients,and the male-male donor-recipient transplant pattern was associated with the poorest post-LT survival.Livers from male donors may provide the most benefit to female recipients.Our results indicate that sex should be considered as a critical factor in organ allocation. 展开更多

Introduction Organ transplantation increases survival and improves qual-ity of life to many patients with end-stage organ failure.Or-gan shortage is a worldwide problem that restricts organ trans-plantation[1].Organ procurement and preservation as well as ischemia-reperfusion injury(IRI)after transplantation are the im-portant factors affecting prognosis of recipients.Since the de-velopment of organ transplantation technology in the 20th cen-tury,organ protection technology has been a most promising con-cept in this field.Organ preservation solutions such as the Collins solution,University of Wisconsin(UW)solution,and histidine-tryptophan-ketoglutarate(HTK)solution were developed sequen-tially[2],which developed rapidly in static cold storage(SCS)tech-niques.SCS remains the standard preservation technique for organ transplantation[2]. 展开更多

目的探讨雷帕霉素(rapamycin,Rap)对大鼠肾脏缺血再灌注损伤的保护作用及机制。方法将24只SD大鼠分为假手术组(Sham)、缺血再灌注损伤模型组(I/R)、低剂量Rap组、高剂量Rap组,术前3d开始灌胃给药,Sham组及I/R组分别给予生理盐水0.5ml/d... 目的探讨雷帕霉素(rapamycin,Rap)对大鼠肾脏缺血再灌注损伤的保护作用及机制。方法将24只SD大鼠分为假手术组(Sham)、缺血再灌注损伤模型组(I/R)、低剂量Rap组、高剂量Rap组,术前3d开始灌胃给药,Sham组及I/R组分别给予生理盐水0.5ml/d,低剂量Rap组及高剂量Rap组每天分别给予0.5ml的1mg/kg和2mg/kg浓度的Rap,维持至术后7d,并在术后第7天给药后2h后收集肾脏组织及血液标本。血生化检测尿素氮及血肌酐;HE染色检测组织病理损伤程度;TUNEL染色检测组织细胞凋亡并计数;Western印迹及实时定量聚合酶链反应检测LC3B、P62、Beclin1、mTOR等因子mRNA水平及蛋白表达;ELISA检测谷胱甘肽(glutathione,GSH)、超氧化物歧化酶(superoxidedismutase,SOD)、丙二醛(malondialdehyde,MDA)、活性氧(reactiveoxygenspecies,ROS)、白细胞介素-6(interleukin-6,IL-6)、肿瘤坏死因子-α(tumornecrosis factor-alpha,TNF-α)表达水平。结果I/R组血清肌酐、尿素氮水平较Sham组明显上升;高剂量Rap组血清肌酐、尿素氮水平较I/R组明显下降;HE染色结果显示,Sham组大鼠肾组织结构正常,I/R组大鼠肾小管结构排列紊乱,可见上皮细胞扁平化、坏死和蛋白管型,肾小管Paller评分明显升高;对比I/R组,Rap两组损伤明显减轻;TUNEL染色结果显示,Rap两组凋亡细胞均较I/R组显著减少。I/R与Sham组相比,LC3B和Beclin1基因表达降低,P62和mTOR基因呈高表达;与I/R组比较,高剂量Rap组LC3B和Beclin1基因呈高表达,P62和mTOR基因呈低表达,同时高剂量Rap组GSH、SOD水平显著升高,MDA、ROS显著降低,且IL-6、TNF-α表达明显减少。结论Rap通过抑制细胞氧化应激及炎症反应减轻大鼠肾脏缺血再灌注损伤,其作用机制可能是Rap促进了细胞自噬水平及抑制细胞凋亡。 展开更多
