New Developments in Managing Variceal Bleeding

Liver cirrhosis is the end stage of chronic liver disease, independent of etiology, and is characterized by accumulation of fibrotic tissue and conversion of the normal liver parenchyma into abnormal regenerative nodules. Complications include portal hypertension (PH) with gastroesophageal varices, ascites, hepatorenal syndrome, hepatic encephalopathy, bacteremia, and hypersplenism. The most life-threatening complication of liver cirrhosis is acute variceal bleeding (AVB) which is associated with increased mortality that, despite recent progress in management, is still around 20% at 6 weeks. Combined treatment with vasoactive drugs, prophylactic antibiotics, and endoscopic techniques is the recommended standard of care for patients with acute variceal bleeding. There are many promising new modalities including the combination of coil and glue injection for management of bleeding or non-bleeding gastric varices and hemostatic powder application, that requires minimal expertise, when performed early after admission of a cirrhotic patient with AVB and overt hematemesis acting as a bridge therapy till definitive endoscopic therapy can be performed in hemodynamically stable conditions and without acute bleeding.
