Littoral cell angioma of the spleen: case report and literature review.

Littoral cell angioma is an extremely rare splenic vascular tumor originating from the cells lining the splenic red pulp sinuses. Approximately 150 cases of littoral cell angioma have been reported since 1991. Its clinical manifestation is usually asymptomatic and is mostly diagnosed as an incidental finding through abdominal imaging.

LIVER TRANSPLANTATION IN PATIENTS WITH PRIMARY SCLEROSING CHOLANGITIS: A MULTICENTRIC STUDY.

Background: The prevalence of primary sclerosing cholangitis (PSC) in the general population has not yet been clearly established. The management of PSC should focus on delaying the progression of the disease and restraining its complications. The only curative therapy for the disease remains liver transplantation (LT).

Liver Transplantation Using Prolonged Cold Ischemia Time Grafts Preserved With Institute George-Lopez-1 Solution.

Institute George-Lopez-1 (IGL-1) solution is a preservation solution with lower potassium and lower viscosity than the University of Wisconsin solution that has been recently used in liver transplantation. In the present series, we compare the outcome of liver grafts from brain-dead donors preserved in IGL-1cold storage solution, with cold ischemia times (CITs) longer than 8 hours and those less than 8 hours. Two hundred fifty-two liver transplantations performed from January 2014 to December 2016 at Hospital Santa Isabel, Blumenau, Brazil, were retrospectively analyzed.

Use of Georges Lopez Institute Preservation Solution IGL-1 in Pancreas Transplantation: A Series of 47 Cases.

Background: Graft preservation continues to be one of the main pillars of pancreas transplantation (PT). Surgical complications, possibly caused or facilitated by organ damage during preservation, continue to occur more frequently after PT than for any other abdominal organ. During the past few years, the Georges Lopez Institute preservation solution IGL-1 has been introduced with satisfactory results for the perfusion and cold storage of abdominal grafts such as kidney and liver.

Transection of the hepatic parenchyma associated or not with the contralateral portal vein branch ligature and its effect in liver regeneration.

Objective: To analyze the influence of portal vein ligation in hepatic regeneration by immunohistochemical criteria.

Methods: Ten pigs divided into two groups of five animals underwent hepatectomy in two stages, and the groups were differentiated by ligation or not of the left portal vein tributary, which is responsible for vascularization of the left lateral and medial lobes of the pig liver. Five days after the procedure, the animals underwent liver biopsies for further analysis of histological and immunohistochemical with marker Ki67.
