In an age of patient-tailored treatments, in liver transplantation as well the aim is to offer the best suitable graft to the patient who can benefit from it, also expanding the criteria for organ acceptance and allocation. With the intent of developing strategies to increase the donor pool, we set-up a multicenter study involving 3 Liver Transplant Centers in Italy: patients undergoing liver transplantation between March 03, 2004, and May 21, 2010, were retrospectively evaluated. 1408 patients underwent liver transplantation during the study period, 28(2%) received the graft from hepatitis B surface antigen positive(HBs Ag)-positive deceased donors. The average follow-up after liver transplantation was 63.7 mo [range: 0.1-119.4; SD ± 35.8]. None Primary nonfunction, re-liver transplantation, early or late hepatic artery thrombosis occurred. The 1-, 3-and 5-year graft and patient survival resulted of 85.7%, 82.1%, 78.4%. Our results suggest that the use of HBs Agpositive donors liver grafts is feasible, since HBV can be controlled without affecting graft stability. However, the selection of grafts and the postoperative antiviral therapy should be managed appropriately.展开更多

The number of liver transplantations has increased steadily while the number of organ donors has remained relatively constant. Thus a great disparity has developed between the demand and supply of donor organs and remains a major limiting factor for further expansion of liver transplantation. Although many procedures, such as split liver[1] , living-related transplantation[2] , and xenotransplantation[3], have been attempted clinically to overcome the shortage, it is hoped that livers harvested from non-heart-beating donors (NHBDs) would alleviatethe problem of organ shortage, which again becomes the focus of attention[4-9]. However, sensitivity of the liver to warm ischemia remains a major worry for use of theNHBDs. The aim of this animal study was to assess if murine liver could tolerate prolonged period of warm ischemia and to determine the optimum timing of intervention in the cadaver donor in order to preserve liver viability.展开更多

METHODS: Organ damage was classified into three tiers, from 1-3, with the latter rendering the organ nontransplantable. For 12 consecutive months starting in January of 2014, 36 of 58 organ procurement organization's(OPO)'s prospectively submitted quality data regarding organ damage(as reported by the transplanting surgeon and confirmed by the OPO medical director) seen on the procured organ.RESULTS: These 36 OPOs recovered 5401 of the nations' s 8504 deceased donors for calendar year 2014.A total of 19043 organs procured were prospectively analyzed. Of this total, 59 organs sustained damage making them non-transplantable(0 intestines; 4 pancreata; 5 lungs; 6 livers; 43 kidneys). The class 3 damage was spread over 22(of 36) reporting OPO's.CONCLUSION: While damage to the procured organ is rare with organ loss being approximately 0.3% of procured organs, loss of potential transplantable organs does occur during procurement.展开更多

To allow more patients to be transplanted before they die on the waitlist an increase in the number of donors is necessary. Patients with devastating irreversible brain injury, if medically suitable, are potential deceased donors and strategies are needed to successfully convert them into actual donors. Multiple steps in the process of deceased organ donation can be targeted to increase the number of organs suitable for transplant. In this review, after describing this process, we discuss current challenges and potential strategies to expand the pool of deceased donors.展开更多
