Background And Study Aims: The effect of sclerotherapy of esophageal varices on the development of gastric varices is a controversial question. The aim of the present study was to evaluate prospectively the presence and development of gastric varices as a consequence of esophageal variceal sclerotherapy.
Patients And Methods: We prospectively studied 227 patients, all of whom had liver cirrhosis at the time of the first bleeding episode due to esophageal varices. All patients were treated with emergency endoscopic sclerotherapy, and further courses of sclerotherapy to eradicate the varices were given at seven-day intervals for three sessions, and then every fifteen days until eradication was complete. At the time of inclusion in the study, patients were divided in two groups: group A, with initial gastric varices, and group B, without any gastric varices initially.
Results: Group A included 138 patients (60.8%), in 99 of whom (71.7%) disappearance of the gastric varices was observed. In 63 cases (63.6%) the varices were eliminated during the sclerotherapy treatment, before the eradication of esophageal varices; in 36 cases (36.4%), the gastric varices disappeared after the eradication of the esophageal varices. Group B included 89 patients (32.9%); in 78 of them (87.6%), no appearance of gastric varices was observed, while in 11 (12.4%), gastric varices appeared.
Conclusion: From these data, it can be concluded that sclerotherapy of esophageal varices cannot be a determinant factor either for the appearance of gastric varices or for their subsequent risk of bleeding.

Background: Transjugular intrahepatic portosystemic shunt (TIPS) is an effective intervention for managing complications of portal hypertension, particularly acute variceal bleeding (AVB). While effective in reducing portal pressure and preventing rebleeding, TIPS is associated with a considerable risk of overt hepatic encephalopathy (OHE), a complication that significantly elevates mortality rates.
Aim: To develop a machine learning (ML) model to predict OHE occurrence post-TIPS in patients with AVB using a 5-year dataset.

Background: Portal vein thrombosis (PVT) leads to portal hypertension (PH) with its sequelae. Computed tomography spleno-mesenterico-portography (CT-SMPG) combines sequential CT spleno-portography and CT mesenterico-portography. CT-SMPG comprehensively illustrates the venous hemodynamic changes due to PH.

Background: Dyskeratosis congenita is a rare genetic disease due to telomere biology disorder and characterized by heterogeneous clinical manifestations and severe complications. "Porto-sinusoidal vascular disease" has been recently proposed, according to new diagnostic criteria, to replace the term "idiopathic non-cirrhotic portal hypertension." TERT plays an important role in telomeric DNA repair and replication.

Gastric varices (GVs) are dilated veins in the stomach submucosa, typically caused by portal hypertension. A prompt diagnosis is needed, given the significant risk of bleeding and mortality. Endoscopic cyanoacrylate injections are widely adopted for treating GV due to their efficacy in preventing rebleeding with lower complication rates.

Background: Gastro-esophageal variceal hemorrhage (GEVH) is one of the major causes of life-threatening gastrointestinal bleeding in children. Medical, endoscopic, angiographic, and surgical interventions can be utilized in treatment. In this case report, we describe partial splenic artery embolization for refractory GEVH due to portal vein thrombosis.
