Approximately one in six patients with portal hypertension who develop varices at sites of portosystemic venous collaterals has gastric varices due to hepatofugal flow into the gastric veins. Bleeding from gastric varices, though less common, has a higher mortality and morbidity compared to bleeding esophageal varices, which are easier to manage endoscopically. The efferent channel for gastric ...

Anastomotic varices are an uncommon cause of variceal bleeding. After choledochojejunostomy, the anastomosed afferent jejunal loop may have a propensity to form varices, with hepatopetal flow [1,2]. Endoscopic sclerotherapy has the potential to cause intrahepatic obstruction of the portal vein [3–5]. This report describes endoscopic sclerotherapy with a high concentration of n-butyl-2-cyanoacry...
