[Giant lipomas or retroperitoneal liposarcomas? Controversies in their diagnosis and treatment].

Background: Retroperitoneal lipomas are extremely rare tumors that must be differentiated from well-differentiated liposarcomas (WD-LPS).

Objectives: To summarize the evidence about giant retroperitoneal lipomas or liposarcomas; and to elaborate recommendations for their management.

Data Sources: A systematic literature search from January 1985 to December 2019 and a review of our own cases was performed.

Liver Transplantation for Hepatic Trauma: A Study From the European Liver Transplant Registry.

Background: Liver transplantation is the most extreme form of surgical management of patients with hepatic trauma, with very limited literature data supporting its use. The aim of this study was to assess the results of liver transplantation for hepatic trauma.

Methods: This retrospective analysis based on European Liver Transplant Registry comprised data of 73 recipients of liver transplantation for hepatic trauma performed in 37 centers in the period between 1987 and 2013.

Orthotopic Liver Transplantation in an Adult With Biliary Atresia, Situs Inversus, and Inferior Cava Vein Absence: A Case Report.

Background: We report the case of a 34-year-old man who underwent Kasai portoenterostomy for biliary atresia at 6 weeks of age. In 2011, pulmonary hypertension was diagnosed and he began treatment with sildenafil. In 2012, he presented with an episode of upper gastrointestinal bleeding secondary to esophageal varices resistant to treatment.

Treatment of hepatocellular carcinoma in the transplant era.

Background: hepatocellular carcinoma (HCC) is one of the most frequent malignant diseases of the liver. It is clearly related to cirrhosis, especially to that caused by liverbound viruses. This study addresses the behavior of this disease in patients treated under different protocols at two third-level hospitals.

Liver transplantation in patients with hepatocellular carcinoma: factors implicated in tumor relapse.

Introduction: Liver segmental resection and liver transplantation are both treatments intended for healing liver cancer. An adequate selection of patients eligible for transplantation is crucial, since organs available for transplants are usually scarce. For this reason, awareness of the prognostic factors of relapse is of great importance.
