Cyclosporine A (CsA), though better know as an immunosuppressant, has been shown to mitigate warm IRI in a variety of organ types, including the liver. However, there is little evidence for CsA in preventing hepatic IRI in the transplant setting. MATERIAL AND METHODS In the present study, we tested the effect of CsA on hepatic IRI in a large-animal ex vivo model of donation after circulatory death (DCD). Porcine donors were pre-treated with either normal saline control or 20 mg/kg of CsA. Animals were subject to either 45 or 60 minutes of warm ischemia before hepatectomy, followed by 2 or 4 hours of cold storage prior to reperfusion on an ex vivo circuit. Over the course of a 12-hour perfusion, perfusion parameters were recorded and perfusate samples and biopsies were taken at regular intervals. RESULTS Peak perfusate lactate dehydrogenase was significantly decreased in the lower-ischemia group treated with CsA compared to the untreated group (4220 U/L [3515-5815] vs 11 305 [10 100-11 674]; P=0.023). However, no difference was seen between controls and CsA-treated groups on other parameters in perfusate alanine or asparagine aminotransferase (P=0.912, 0.455, respectively). Correspondingly, we found no difference on midpoint histological injury score (P=0.271). CONCLUSIONS We found minimal evidence that CsA is protective against hepatic IRI in our DCD model.","PeriodicalId":7935,"journal":{"name":"Annals of Transplantation","volume":"29 ","pages":"e941054"},"PeriodicalIF":1.1,"publicationDate":"2024-01-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC10838008/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139575046","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

MATERIAL AND METHODS The clinical data of 187 liver transplantation recipients were retrospectively analyzed. Recipients were divided into conventional and modified groups. The technical point of the modified group is to preserve at least 2 cm of the distal gastroduodenal artery, and pay special attention to preserve the superior pancreaticoduodenal artery to ensure the distal blood supply to the common bile duct. RESULTS The modified group had significantly shorter operative time (7.17 vs 7.98) h (P<0.001) and less intraoperative blood loss (2715.40 vs 3434.93) ml (P=0.003) than the conventional group. The incidence of postoperative biliary complications (including anastomotic biliary leakage, ischemic bile duct stenosis, and anastomotic bile duct stenosis) in the modified group (4/114, 4.1%) was significantly lower (15/73, 20.5%) (P<0.001). There was no significant difference in the intraoperative cold and warm ischemia time and postoperative hospital stay length between the 2 groups. In addition, there was no significant difference in the effect of cardiac-death and brain-death sources on perioperative biliary complications, while the peak postoperative transaminase and total bilirubin were higher in patients receiving the donor liver of cardiac death (P<0.05). CONCLUSIONS Preserving the integrity of the donor gastroduodenal artery and surrounding tissue is beneficial to protect the blood supply of the extrahepatic bile duct, and can reduce the incidence of biliary complications.","PeriodicalId":7935,"journal":{"name":"Annals of Transplantation","volume":"28 ","pages":"e941699"},"PeriodicalIF":1.1,"publicationDate":"2023-12-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC10757381/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139037318","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We conducted this study to evaluate the changes in liver transplantation over the last 2 decades. MATERIAL AND METHODS Three hundred cases of liver transplantation encountered between 1997 and 2019 in Nagasaki University Hospital were divided into 3 groups: Era 1 (cases no. 1-100), Era 2 (cases no. 101-200), and Era 3 (cases no. 201-300). Several items were compared among the groups. RESULTS There were no cases of deceased-donor liver transplantation in Era 1, 1 case in Era 2, and 12 cases in Era 3. The proportion of virus-related disease was significantly lower in Era 3 compared to other eras. In contrast, the proportion of alcoholic liver cirrhosis was significantly higher in Era 3 (27%) than Era 1 (7%) and Era 2 (10%) (P<0.01). In Era 1, the right lobe was selected most frequently, but in Eras 2 and 3, the left lobe was more frequently selected.

A liver vascular anomaly causes compensatory changes in other blood vessels connected to it because of the close relationship between them. Obstruction of the retrohepatic inferior vena cava and the second hilum can form the intrahepatic venous network and the vertebral venous plexus pathway, which can be demonstrated by hepatic venography and anatomical and autopsy studies. CASE REPORT A Tibetan woman, age 31, with hepatic alveolar echinococcosis and unique intrahepatic hemodynamic features, was referred to our center and underwent successful ex vivo liver resection and autotransplantation. We report our experience and review the literature. In this clinical case, we performed an ex vivo liver resection and autotransplantation without hepatic inferior vena cava reconstruction. After surgery, the circulatory system hemodynamic remained stable, and blood flow in the liver and trunk was unhindered. The patient underwent an uneventful hospitalization and recovery. CONCLUSIONS This clinical case demonstrates the unique venous access, hemodynamic alterations, and surgical decision-making that follow the invasion of significant hepatic vessels by alveolar echinococcosis lesions. HAE exhibits unique collateral vessels, which are uncommon in other diseases. Additionally, this kind of therapy offers fresh perspectives for the surgical treatment of end-stage HAE.","PeriodicalId":7935,"journal":{"name":"Annals of Transplantation","volume":"28 ","pages":"e941521"},"PeriodicalIF":1.1,"publicationDate":"2023-11-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC10638859/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"71477302","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
