RESUMO
BACKGROUND: Orthotopic liver transplantation is an essential approach performed in several centers around the world. Our center lies in northeastern Brazil and has performed this procedure since 2002. In 2011, 126 liver transplants were performed at our institution. METHODS: This study is a retrospective and descriptive analysis of the data collected from the medical records of those transplants. Epidemiological and clinical aspects were considered in this evaluation. The outcome analysis considered overall survival rates within 30 days and 1 year after transplantation. RESULTS: The sample of 124 patients showed 60% of all patients came from other regions, particularly the North and Midwest regions of Brazil, which had a combined population of >30 million in 2011. The most frequent etiologies for end-stage liver disease were hepatitis C and alcoholism. The average calculated MELD (Model for end-stage liver disease) was 21.0. Patient survival curves were 88.4% after 30 days and 81.5% after 1 year. CONCLUSION: The development of effective perioperative management for this procedure resulted in improved outcomes. Our center's performance is based on a multidisciplinary approach performed by qualified personnel, careful pre- and postoperative follow-up and continuous improvement of services.

Hepatocellular carcinoma (HCC) is the fifth most common cancer in the world and the third leading cause of cancer-related death. In this study, we sought to assess the outcome of patients with HCC who underwent orthotopic liver transplantation (OLT) in a center in the northeast of Brazil. Between May 2002 and July 2008, 294 OLTs were performed at our center. In 45 patients, HCC was confirmed by histological examination of the explant. Patients were predominantly men of ages ranging from 14-67 years. Hepatitis C virus was involved in 55.4% of the cases. Alpha fetoprotein (AFP) levels were normal in 65.2% of the patients and surpassed 100 ng/mL in only 10.4%. The median waiting time on the list was 10 months. Seventeen patients (37.7%) presented a solitary nodule, 19 (42.2%) had 2 or 3 nodules, and 9 patients (20%) had more than 3 nodules. The maximal diameter of the largest tumor was <3 cm in 26 patients (57.7%) and exceeded 5 cm in 6 patients (13.3%). Ten tumors were well differentiated, 32 were moderately differentiated, and 3 were poorly differentiated. Eleven tumors showed microvascular invasion. There have been 4 tumor recurrences. There was an association between microvascular invasion and tumor recurrence with a statistically significant relative risk. In conclusion, OLT is an excellent option for patients with HCC. The recurrence rate was low (<10%). However, we believe that more prospective studies are needed about OLT beyond the Milan criteria because our study suggested that microvascular invasion may be more important than tumor size or number.

Sequential or domino liver transplantation is a well-established procedure for patients with familial amyloidotic polyneuropathy (FAP). Donation for domino liver transplantation imposed the resection of the inferior vena cava along with the liver, requiring complete suprarenal vena cava clamping and usually the use of venovenous bypass. We describe a successful case in which it was possible to perform the FAP hepatectomy by the piggyback technique.
