Time of Dropout From the Liver Transplant List in Patients With Hepatocellular Carcinoma: Clinical Behavior According to Tumor Characteristics and Severity of Liver Disease.

Background: Prolonged time on the waiting list affects post-transplant survival of patients with hepatocellular carcinoma (HCC). However, it is not yet known which patients will be at higher risk for early dropout from the list. We investigate specific risk factors for early waiting list dropout in patients with HCC.

Liver transplantation: history, outcomes and perspectives.

In 1958 Francis Moore described the orthotopic liver transplantation technique in dogs. In 1963, Starzl et al. performed the first liver transplantation.

Intestinal and multivisceral transplantation.

Intestinal transplantation has shown exceptional growth over the past 10 years. At the end of the 1990's, intestinal transplantation moved out of the experimental realm to become a routine practice in treating patients with severe complications related to total parenteral nutrition and intestinal failure. In the last years, several centers reported an increasing improvement in survival outcomes (about 80%), during the first 12 months after surgery, but long-term survival is still a challenge.

Impact of renal failure on liver transplantation survival.

Renal failure after orthotopic liver transplantation (OLT) is a common complication (ranging from 12% to 70%) associated with worse outcomes, particularly when it requires renal replacement therapy (RRT). Renal dysfunction is a common scenario among waiting list patients. It can lead to a worse prognosis after OLT, due to an increased incidence of postoperative renal failure.

Impact of cumulative risk factors for expanded criteria donors on early survival after liver transplantation.

There are various options to help overcome the organ shortage, including performing transplants using grafts from marginal donors with characteristics previously described as unacceptable because of the high risk of graft failure. Nowadays, expanded criteria donors for liver transplantation (OLT) is a strategy used routinely by many teams. Some donor features have been suggested to jeopardize initial function or survival; when these features are aggregated, they may impact prognosis.

Donor liver dysfunction: application of a new scoring system to identify the marginal donor.

Livers from marginal donors are increasingly used for transplantation due to the shortage of donor organs. The definition of a marginal donor remains unclear; prediction of organ function is a challenge. In the literature the use of steatotic livers has been associated with poor liver function or even primary dysfunction of the allograft.

Correlation between graft arterial anatomy and biliary complications after liver transplantation.

Knowledge of the arterial vascular anatomy of the liver is important for orthotopic liver transplantation (OLT) because the lack of an adequate arterial blood supply results in biliary and parenchymal complications or graft loss. A number of reports have shown a relationship between aberrations of graft arteries and an increased incidence of early or late complications. Recent studies suggest no differences unless multiple anastomoses are required.

Analysis of Model for End-Stage Liver Disease (MELD) score in a liver transplantation waiting list.

Background: The Model for End-Stage Liver Disease (MELD) was introduced in 1999 to quantify the 3-month prognosis of cirrhotic patients after a transjugular intrahepatic portosystemic shunt (TIPS). Because of the imbalance between organ donors and patients on the waiting list, the MELD was adopted by the United States in 2002 to allocate liver grafts for transplantation. Preliminary results have indicated a reduction in waiting list deaths and an increase in transplantation rates for candidates.

Results of urgent liver retransplantation in the state of São Paulo, Brazil.

The treatment of end-stage liver disease includes transplantation as a life-saving procedure although it has serious complications of hepatic artery thrombosis, liver dysfunction, or primary nonfunction, which frequently lead to the need for retransplantation. According to various reports, the incidence of retransplantation is around 10%. Given the critical organ shortage, the chance for a second transplant remains a controversial discussion in medical, ethical, and economic grounds because patient and graft survival rates after retransplantation are lower than those for primary transplantations.

Early perioperative death associated with reexpansion pulmonary edema during liver transplantation.

Hydrothorax is a frequent finding in patients with end-stage liver disease. During the hepatectomy phase of liver transplantation, it is often needed to evacuate large pleural effusions. The acute expansion of the collapsed lung can cause reexpansion pulmonary edema with variable clinical significance.

Apolipoprotein and lipid abnormalities in chronic liver failure.

Total serum lipids, as well as apolipoproteins A-I (apo A-I) and B (apo B), were determined in 74 patients with chronic liver failure without cholestasis and in 82 normal subjects. The VLDL, LDL and HDL lipid fractions were reduced in the liver failure group by 36%, 24% and 46%, respectively (P < 0.001).

[Bacterial endocarditis in patients over 60 years of age].

Bacterial endocarditis (BE) is a disease difficult to diagnose and with poor prognosis in older people. A total of 76 episodes of this disease occurring in 73 patients were studied with particular attention to clinical manifestation, underlying heart disease, etiological germs, hospitalary mortality and prognosis within 6 months from diagnosis. All patients were 60 years old or older.
