Background: Partial ligation of the portal vein has been shown to induce not only prehepatic portal hypertension but also esophageal varices in the rat. We developed an esophageal endoscopic system for endoscopic sclerotherapy of esophageal varices in rats. In the present study the efficacy of three sclerosing agents, 1% polidocanol, 5% ethanolamine oleate, and 99.5% ethanol, was compared, using this model.
Methods: Sclerosing agents were injected paravariceally in 42 rats with partial portal vein ligation. Their efficacy was compared endoscopically and histologically.
Results: Ethanol induced the most severe ulcers and subsequent stricture formation. The damage induced by 1% polidocanol was mild and healed quickly, whereas 5% ethanolamine oleate induced moderate damage. The varices disappeared because of fibrosis that developed after ulceration.
Conclusions: The results were consistent with the known properties of these three agents, suggesting that the esophageal endoscopic system for sclerotherapy in rats provides a useful method for experimental studies of sclerotherapy.

Portal hypertension is a hemodynamic abnormality that complicates the course of cirrhosis, as well as other diseases that affect the portal venous circulation. The development of portal hypertension compromises prognosis, especially when it rises above a certain threshold known as clinically significant portal hypertension (CSPH). In the consensus conference on Portal Hypertension promoted by the Spanish Association for the Study of the Liver and the Hepatic and Digestive diseases area of the Biomedical Research Networking Center (CIBERehd), different aspects of the diagnosis and treatment of portal hypertension caused by cirrhosis or other diseases were discussed.

Acute gastric variceal bleeding is a rare but serious complication of portal hypertension. Initial therapy for bleeding gastric varices focuses on acute hemostasis. In this regard, endoscopic cyanoacrylate injection (ECI) is the first-line approach.

Methods: This was a retrospective study conducted between April 2012 and April 2022.

Wilson's disease is an autosomal recessive disorder that affects copper transport due to deficiency of ceruloplasmin and causes deposition of copper mainly in the liver, brain and cornea. It causes hepatic and/or neuropsychiatric manifestations. This copper deposition causes cirrhosis of the liver, encephalopathy and liver failure.

Background: In cirrhotic patients, portal hypertension increases mortality after surgery. We evaluated the impact of pre-operative transjugular intrahepatic portosystemic shunt (TIPS) on the outcomes of bariatric surgery in cirrhosis.
Methods: Multicentric retrospective cohort.
