Intrahepatic splenosis is a rare disease that is often difficult to distinguish from liver malignancy, especially hepatocellular carcinoma. The cause of intrahepatic splenosis may be though the auto-transplantation of splenic tissue on the surface of the liver. The authors report a case of intrahepatic splenosis that presented as a liver tumour in an 81-year-old female treated for autoimmune hepatitis, who had no history of splenectomy or abdominal trauma. Laparoscopic hepatectomy was performed and the specimen demonstrated characteristic histopathological findings of the spleen. Only one case of a patient who had no history of splenectomy or abdominal trauma has been reported in the literature. It may be hypothesised that erythropoiesis induced by local hypoxia in the chronic hepatitis may cause the growth of splenic erythrocytic progenitor cells, which have migrated via portal vein to the liver.","PeriodicalId":92358,"journal":{"name":"European medical journal.

It is associated with numerous hepatobiliary complications including an increased risk of malignancy (in particular, cholangiocarcinoma) and biliary tract stone formation. The evaluation of biliary strictures in patients with PSC is especially challenging, with imaging and endoscopic methods having only modest sensitivity for the diagnosis of cholangiocarcinoma, and treatment of biliary strictures poses a similarly significant clinical challenge. In recent years, peroral cholangioscopy has evolved technologically and increased in popularity as an endoscopic tool that can provide direct intraductal visualisation and facilitate therapeutic manipulation of the biliary tract. However, the indications for and effectiveness of its use in patients with PSC remain uncertain, with only a few studies performed on this small but important subset of patients. In this review, the authors discuss the available data regarding the use of peroral cholangioscopy in patients with PSC, with a focus on its use in the evaluation and management of biliary strictures and stones.</p>","PeriodicalId":92358,"journal":{"name":"European medical journal.

Relaxin is a member of the insulin/relaxin superfamily of peptide hormones. Originally known for its roles in pregnancy, relaxin promotes reproductive tissue remodelling and regulates vascular changes, including increased arterial compliance and reduced vascular resistance. Outside of pregnancy, relaxin plays a major role in the protection of organs from excess extracellular matrix accumulation, as demonstrated by the relaxin-null mouse, which develops widespread fibrosis with ageing. Relaxin reduces scarring due to excess collagen deposition by inhibiting collagen production while simultaneously promoting its degradation and can reduce established fibrosis in several animal models of extracellular matrix-associated disease, including liver fibrosis. Treatment with relaxin reduces the myofibroblastic phenotype of activated hepatic stellate cells, the major hepatic collagen-producing cell in fibrosis and cirrhosis. Relaxin also has haemodynamic effects, including vasodilation, and can reduce portal hypertension associated with cirrhosis. In this review, a brief overview of hepatic fibrosis and the role of the hepatic stellate cell will be presented, followed by an introduction to relaxin and its actions. The use of relaxin to treat preclinical models of fibrotic diseases, including liver diseases, will also be discussed. Finally, the completed, current, and ongoing clinical trials of relaxin in human disease will be described, followed by the limitations and future directions for the use of relaxin for disease treatment.","PeriodicalId":92358,"journal":{"name":"European medical journal.
