preoperative sodium level; p = 0.037, model of end-stage liver disease score >25; p = 0.048, primary sclerosing cholangitis; p = 0.001, malignancy; p = 0.026, donor age >60, macrovesicular graft steatosis; p = 0.001, duct-to-duct anastomosis; p = 0.004, long anhepatic phase; p = 0.04, cold ischemic time >12 h; p = 0.043, use of T-tube; p = 0.032, insufficient flush of bile ducts; p = 0.001, acute rejection; p = 0.003, cytomegalovirus infection; p = 0.004 and hepatic artery thrombosis; p = 0.001. The management was surgical in case of biliary leakage, and interventional radiology or endoscopic retrograde cholangiopancreatography in case of biliary stricture. Mapping of miRNA profile is a new field of research. Nemes-Doros score is a useful tool in the estimation of hepatic artery thrombosis. Management of BCs requires a multidisciplinary expert team.

Extended criteria donors (ECDs) have an impact on early allograft dysfunction (EAD), biliary complications, relapse of hepatitis C virus (HCV), and survivals. Early allograft dysfunction was frequently seen in grafts with moderate and severe steatosis. Donors after cardiac death (DCD) have been associated with higher rates of graft failure and biliary complications compared to donors after brain death. Extended warm ischemia, reperfusion injury and endothelial activation trigger a cascade, leading to microvascular thrombosis, resulting in biliary necrosis, cholangitis, and graft failure. The risk of HCV recurrence increased by donor age, and associated with using moderately and severely steatotic grafts. With the administration of protease inhibitors sustained virological response was achieved in majority of the patients. Donor risk index and EC donor scores (DS) are reported to be useful, to assess the outcome. The 1-year survival rates were 87% and 40% respectively, for donors with a DS of 0 and 3. Graft survival was excellent up to a DS of 2, however a DS >2 should be avoided in higher-risk recipients. The 1, 3 and 5-year survival of DCD recipients was comparable to optimal donors. However ECDs had minor survival means of 85%, 78.6%, and 72.3%. The graft survival of split liver transplantation (SLT) was comparable to that of whole liver orthotopic liver transplantation. SLT was not regarded as an ECD factor in the MELD era any more. Full-right-full-left split liver transplantation has a significant advantage to extend the high quality donor pool. Hypothermic oxygenated machine perfusion can be applied clinically in DCD liver grafts. Feasibility and safety were confirmed. Reperfusion injury was also rare in machine perfused DCD livers. I) IntroductionAs discussed earlier, extended criteria donors are used widely. In this chapter a review is given about the impact of ECD on the outcome. Living related liver transplantation is discussed shortly, whether the partial grafts can still be regarded as ECD or not. Machine perfusion, as a possible management was also reviewed briefly. Outcome parameters are divided as possible complications, and survival results. Complications are listed as early graft dysfunction, biliary complications, HCV recurrence. Survival rates are summarized separately. Split, and living related LT discussed briefly, and finally the machine perfusion, as a possible future aspect is summarized. Silberhummer et al figured out the recipients' condition by the delta-MELD: as the difference between the MELD at transplantation and the MELD at listing. Patients with a both delta-MELD>1 and an ECD>2 together had a higher chance to develop EAD, and also significantly higher risk for mortality [3]. Others report a similar incidence of EAD, PNF, acute rejection, biliary complication and also that ECD had no significant effect on either ICU stay or duration of postOLT ventilation, and also the postOLT laboratory test, bleeding, biliary and vascular complication rates were similar in ECD and non-...

Recurrent PSC significantly affects long-term mortality and graft loss. Younger age at OLT, higher donor BMI and severe active IBD may be associated with PSC recurrence. PreOLT total colectomy might have protective effect against rPSC.

Bevezetés: A szerzők a májátültetést követően kialakult mikrobás fertőzéseket, a mintavételek eredményeit, a multidrug-rezisztencia incidenciáját vizsgálták a hazai betegek körében. Célkitűzés: Tanulmányozták a bakteriális fertőzés kialakulásának kockázati tényezőit, az infekciókhoz kapcsolódó szövődmények előfordulását, lefolyását, és részletes kórokozó-spektrumelemzést végeztek. Módszer: 2003-2012 között májátültetett 408 beteg adatait (281 bakterioló-giai tenyésztést) vizsgálták. Eredmények: A 408 beteg közül 70 betegnél (17%) észleltek klinikai tünetekkel járó fertőzést. A tenyésztési lelet 58 betegnél (14,2%) pozitív, 12 betegnél (2,9%) negatív volt. Hét esetben (12,1%) alakult ki cholangitis, 17 esetben (29,3%) fordult elő hasűri és 28 esetben (48,3%) pulmonalis eredetű fertőzés. Posztoperatív fertőzés gyakrabban lépett fel kezdeti csökkent graftműködés, akut veseelégtelenség, epeúti szövődmény és hasű-ri vérzés mellett. Infekció kialakulása esetén az 1, 3 és 5 éves betegtúlélés 70%, 56% és 56% volt, míg infekció nélkül ez 94%, 87%, 85% volt (p<0,001). A kitenyészett baktériumok 56%-ánál találtak multidrug-rezisztenciát, viszont nem volt szignifi káns különbség a multidrug-rezisztencia pozitív és negatív baktériummal fertőzött csoportok egyéves betegtúlélése között (70,2% mindkettő). Következtetések: Az infekciókontroll, a multidrug-rezisztens kórokozók menedzselése a preventív, higiéniai, izolációs elvek kialakítását, betartását, valamint műtéttechnikai, transzfúziós, antibiotikus stratégiák, folyamatok fejlesztését kell, hogy megcélozza, szakmai csapatmunka keretén belül.

Aim: The aim of this study was to analyse risk factors and colonisations of bacterial infections. Method: The fi les of 408 patients (281 bacterium cultures) were reviewed. Results: Of the 408 patients 70 had a postoperative infection (17%); 58 patients (14.2%) had positive and 12 patients (2.9%) negative bacterial culture results. Cholangitis was found in 7 cases (12.1%), abdominal infection in 17 cases (29.3%), and pulmonal infection in 28 cases (48.3%). Postoperative infection was more frequent in patients with initial poor graft function, acute renal insuffi ciency, biliary complication, and in those with intraabdominal bleeding. The 1-, 3-and 5-year cumulative survival of patients who had infection was 70%, 56% and 56%, respectively, whereas the cumulative survival data of patients without infection was 94%, 87% and 85%, respectively (p<0.001). Multidrug resistance was found in 56% of the positive cultures, however, the one-year survival was not different in patients who had multidrug resistance positive and negative...
