Tačiau tuo metu penkerius metus išgyvendavo tik apie 20% recipientų. Padėtis pasikeitė, kai 1979 metais klinikinėje organų transplantacijoje pradėtas vartoti ciklosporinas A. Recipientų penkerių metų išgyvenamumas vartojant šį imunosupresantą pasiekė 70%. Gerėjant kepenų transplantacijų rezultatams ėmė stigti donorinių organų. Atliekant sumažinto dydžio donorinių kepenų transplantaciją, vienų donorinių kepenų transplantaciją dviem recipientams, kepenų transplantaciją iš gyvo donoro, buvo stengiamasi sumažinti donorinių organų trūkumą. Šiuo metu vis daugiau dėmesio skiriama ksenotransplantacijai. Ksenotransplantacija – pažeistų žmogaus organų pakeitimas gyvūnais audiniais ar organais. Lietuvoje sėkmingos kepenų persodinimo operacijos žengia tik pirmus žingsnius. 1962 metais Vilniuje buvo įkurta Vilniaus universiteto širdies ir kraujagyslių chirurgijos laboratorija, kurioje aktyviai vyko eksperimentinė širdies, inkstų ir kepenų transplantacija. Buvo sukurtas ir kliniškai pritaikytas originalus tuo laikotarpiu ūminio kepenų funkcijos nepakankamumo gydymo metodas. Ruošiantis klinikinei kepenų transplantacijai atliktos 68 ortotopinės kepenų transplantacijos su gyvūnais. 1969 metais Širdies ir kraujagyslių chirurgijos laboratorijoje sukuriamas imunologijos sektorius. Lietuvoje pirmosios kepenų transplantacijos žmogui atliktos 2000 metais Vilniaus universiteto ligoninėje Santariškių klinikose ir Kauno medicinos universiteto klinikose. Nors šios operacijos buvo nesėkmingos, ir toliau aktyviai tobulintasi šioje chirurgijos srityje. 2002 metais Kauno medicinos universiteto klinikose prof. J. Pundziaus, o 2005 metais Vilniaus universiteto ligoninėje Santariškių klinikose prof. K. Strupo vadovaujamos specialistų brigados atliko pirmąsias sėkmingas ortotopines kepenų transplantacijas Lietuvoje.

In 1967, the first successful human liver transplantation was performed by Thomas Starzl at University of Colorado. A year later, Roy Calne from University of Cambridge performed the first successful liver transplantation in Europe. The five-year survival rate was only 20% at that time. The situation changed in 1979 when the immunosuppressive agent cyclosporine A was introduced into clinical practice. The five-year survival rate reached 70%. The improved results of liver transplantation created a new problem – shortage of available organs. Reduced size liver transplantation, split liver transplantation, living donor liver transplantation were the methods to reduce organ shortage. Nowadays much attention is paid to xenotransplantation. Xenotransplantation is the transplantation of tissues or organs from one species to another. Liver transplantation in Lithuania makes only its first steps. In 1962, Laboratory of Heart and Vascular Surgery of Vilnius University was introduced, in which experimental works in the field of heart, kidney and liver transplantation were performed. At that time, the original method of treatment of acute liver insufficiency was introduced and clinically adapted. 68 experimental liver transplantations on laboratory animals were performed. In 1969, in the Laboratory of Heart and Vascular Surgery, the sector of immunology was established. The first attempts to perform human liver transplantation in Lithuania were made in 2000 at Vilnius University Hospital Santariškiu Klinikos and Kaunas Medical University Hospital. These operations were unsuccessful. Nevertheless the transplant teams continued to improve knowledge in this field of surgery. In 2002, the first successful human liver transplantations was performed at Kaunas Medical University Hospital under the guidance of Prof. J. Pundzius, and in 2005 at Vilnius University Hospital Santariškiu Klinikos under the guidance of Prof. K. Strupas.

To date, more than 50,000 liver transplantations have been performed around the world; the survival rate five years after transplantation ranges from 60% to 65%. One of the fundamental objectives for liver transplantation teams is to achieve the best possible quality of life (QOL) for the patients. A concise analysis of the methodology used (15 questionnaires) to measure QOL of patients with liver transplants is described. The authors suggest that now is the time to establish a database so that a validated instrument will be available to compare QOL results from all the liver transplantation programs. Liver transplantation is believed to improve QOL, although there are several problems with some of the papers published on this subject. Some studies are retrospective, whereas in others, patients in bad physical conditions are excluded from the study; in quite a few prospective studies, deaths are not included in the data analysis. Finally, the authors provide a brief, concise analysis of late complications and of recurrence of the disease after liver transplantation, which influence QOL.

Purpose: The aim of this study is to analyze a ten-year single center experience in liver transplantation in Pernambuco - Northeastern region of Brazil. Methods: Data were retrospectively collected from medical records of 302 patients who underwent Orthotopic Liver Transplantation (OLT) between 1998 and 2008 at Oswaldo Cruz University Hospital, Pernambuco – Brazil. We analyzed just the outcomes and survival curve of 195 adult liver transplantation recipients from deceased donor. Results: Data concern liver donor, surgery technical aspects and liver transplantation recipients’ postoperative evolution are presented and discussed. This center has a significant experience in liver transplantation using conventional technique with no venovenous bypass. Efficient management of liver transplantation practice has made it feasible to keep the cold ischemia time within 6-7 hours. Because of the organ shortage, we have used a large amount of extended criteria liver donor. The survival 1-year rata was 76.4%. Conclusion: It is possible to provide a high-quality public medical assistance in an efficient and continuous manner in less developed areas of Brazil.

A liver transplantation (LT) is a surgical procedure that removes a liver that no longer functions properly and replaces it with a healthy liver from a living or deceased donor. It is a viable treatment option for end-stage liver disease and acute liver failure. The most commonly used technique is orthotopic transplantation or deceased donor liver transplantation (DDLT) in which the native liver is removed and replaced by the donor organ in the same anatomic location as the original liver. Ongoing challenges of LT include those concerning donor organ shortages, recipients with more advanced disease at transplant, growing need for transplantation, side effects associated with long-term immunosuppression, toxicities and obesity. Organ shortage has become the most vexing problem in LT, with 10–25% of patients dying while awaiting transplantation. Different ideas has been evolved like living donor liver transplantation (LDLT), marginal donor liver transplantation (MDLT) and  split liver transplantation (SLT) to overcome the growing problem of organ shortage. These techniques are becoming very important in an attempt to narrow the gap between demand and supply of organs. The advances in surgical and anaesthetic techniques, greater understanding of the physiological, haematological, biochemical, microbiological and immunological changes in liver disease and transplantation allowed a multidisciplinary approach that led to better outcomes. These changes, coupled with more effective immunosuppressive and anti-microbial agents and improvements in patient and donor selection, mean that now liver replacement is a routine procedure with excellent long term outcomes.Int.

Introduction: Liver transplantation is established as a lifesaving procedure for patients with acute and chronic liver failure, as well as certain selected malignancies. Due to a continuing organ shortage and ever-growing patient waiting lists, donation after cardiac death (DCD) is becoming more frequently utilized in order to close the gap between “supply and demand”. Methods: A retrospective analysis of DCD and subsequent liver transplantations was performed. Results: From May 2016 to September 2019, a total of 9 DCD liver transplantations were performed in our institution. All cases except one were primary liver transplantations. The recipients comprised 5 (56%) males and 4 (44%) females. The mean DCD donor age was 41±12 (22–57) years, with ventilation duration of 7±1 days and warm ischemia time 19±3 minutes. The average recipient age was 51±22 (4–73) years, with an average cold ischemia 3h:59m±27m and manipulation time of 23±5 minutes. Periprocedural mortality was 1 (11%). Hepatitis C recurrence was documented in 1 (11%) patient. The mean follow-up time was 19±13 (7–37) months. Until now, we have not observed any signs of ischemic cholangiopathy. Conclusion: DCD liver transplantation allows us to enlarge the pool of potential liver grafts, thus decreasing the time spent on the liver recipient waiting list. This paper documents the first series of DCD liver transplantations in the Czech Republic.

There are two causes of graft compression in the large-for-size syndrome (LFSS). One is a shortage of intra-abdominal space for the liver graft, and the other is the size discrepancy between the anteroposterior dimensions of the liver graft and the lower right hemithorax of the recipient. The former could be treated using delayed fascial closure or mesh closure, but the latter may only be treated by reduction of the right liver graft to increase space. Given that split liver transplantation has strict requirements regarding donor and recipient selections, reduced-size liver transplantation, in most cases, may be the only solution. However, surgical strategies for the reduction of the right liver graft for adult liver transplantations are relatively unfamiliar. Herein, we introduce a novel strategy of HuaXi-ex vivo right posterior sectionectomy while preserving the right hepatic vein in the graft to prevent LFSS and propose its initial indications.

The ideal management for end stage liver disease, acute liver failure, and hepatocellular carcinoma (HCC), within specific criteria, is liver transplantation (LT). Over the years, there has been a steady increase in the candidates listed for LT, without a corresponding increase in the donor pool. Therefore, due to organ shortage, it has been substantially difficult to reduce waitlist mortality among patients awaiting LT. Thus, marginal donors such as elderly donors, steatotic donors, split liver, and donors after cardiac death (DCD), which were once not commonly used, are now considered. Furthermore, it is encouraging to see the passing of Acts, such as the HIV Organ Policy Equity (HOPE) Act, enabling further research and development in utilizing HIV grafts. Subsequently, the newer antivirals have aided in successful post-transplant period, especially for hepatitis C positive grafts. However, currently, there is no standardization, and protocols are center specific in the usage of marginal donors. Therefore, studies with longer follow ups are required to standardize its use.

Background: Organ demand for liver transplantation (LT) is constantly increasing. Split liver transplantation (SPLT) is an ideal option for increasing the number of available liver grafts for transplantation and ameliorating organ shortage to a certain degree. However, SPLT for two adult recipients is still not broadly applied. Methods: We retrospectively analyzed the outcomes of SPLT for adult recipients at a single center. All donor, recipient, and transplantation factors were thoroughly investigated to clarify factors affecting patient outcomes after LT. Results: One hundred consecutive adult SPLTs were performed during the study period. Early mortality and 1-year mortality occurred in 21 and 31 recipients, respectively. On multivariate analysis, graft weight (p = 0.036, odds ratio = 0.99, 95% confidence interval = 0.98–0.99) was the independent risk factor associated with early mortality; however, no factor was significantly related to 1-year mortality. On receiver operating characteristic curve analysis, a graft weight of 580 g was identified the cutoff for stratifying outcomes. Recipients transplanted with a graft weighing ≥580 g had significantly better outcome as compared with other recipients (p = 0.001). Moreover, SPLT remarkably provided a better survival benefit for recipients than those on the LT wait-list (p < 0.0001). Conclusions: Given the considerable incidence of wait-list mortality, SPLT for two adult recipients should be encouraged whenever possible to increase the donor pool and benefit patients awaiting LT. Nonetheless, caution should be taken with a smaller graft weight owing to the risk of early graft loss.
