Background: In Chile, organ allocation for liver transplantation (LT) in adults is prioritized according to the MELD-Na score. Exceptions such as Hepatocellular Carcinoma (HCC) and other non-HCC exceptions receive a score called Operational MELD score.

Aim: To evaluate the effectiveness of the MELD-Na score and the operational MELD score as a prioritization system for LT in Chile.

Introduction And Aim: The MELD score has been established as an efficient and rigorous prioritization system for liver transplant (LT). Our study aimed to evaluate the effectiveness of the MELD score as a system for prioritization for LT, in terms of decreasing the dropout rate in the waiting list and maintaining an adequate survival post-LT in Chile.

Materials And Methods: We analyzed the Chilean Public Health Institute liver transplant registry of candidates listed from October 15th 2011 to December 31st 2014.

Post-transplant lymphoproliferative disorder (PTLD) is a major and potentially life-threatening complication after solid-organ transplantation. The aim of this study was to describe the disease characteristics, clinical practices, and survival related to PTLD in adult orthotopic liver transplant (OLT) recipients in South America. We conducted a survey at four different transplant groups from Argentina, Brazil, and Chile.

Liver transplantation is an excellent therapeutic option for terminal liver disease. During the last decades the results of liver transplantation have improved significantly with a patient survival rate of nearly 90% at one year and 80% at 5 years of follow-up. The main indications for liver transplantation include: end-stage liver disease associated to cirrhosis, acute liver failure, and hepatic tumors (mainly hepatocarcinoma).

Sirolimus (SRL) is a new immunosuppressive drug approved for renal transplantation, but is being used increasingly in orthotopic liver transplantation (OLT). Compared with the calcineurin inhibitors, SRL has different mechanisms of action and side effects profile. Thus, this drug offers significant potential advantages over other immunosuppressive agents.

End stage renal disease is not an absolute contraindication for liver transplantation (LT) in patients with end stage liver disease. Actuarial patient and graft survival are comparable for children and adults who undergo LT alone and liver-kidney transplantation (LKT). The most common indications for LKT are the primary hyperoxaluria type I (PH1) and the liver and renal polycystic disease.

Background: The success of orthotopic liver transplantation (OLT) has resulted in its widespread use for different liver diseases.

Aim: To report our 8 years experience with adult OLT at Clinica Alemana de Santiago.

Patients And Methods: In all transplantations done at the center, we recorded patient's overall data and survival, postoperative medical and surgical complications and causes of death.
