Gastroesophageal variceal bleeding - An overview of current treatment options

Gastroesophageal variceal hemorrhage is the most important clinical event that results from portal hypertension. It is a life- threatening condition that demands rapid and efficient treatment. The first step in bleeding control is hemodynamic stabilization and pharmacological treatment, which includes administration of vasoactive drugs and short-term antibiotic prophylaxis. After initial hemodynamic stabilization, endoscopic therapy should be performed. The first choice of endoscopic treatment for esophageal bleeding is endoscopic variceal ligation (EVL), or endoscopic injection sclerotherapy (EIS) if EVL cannot be performed. Several rescue therapies, such as application of balloon tamponade, a self- expandable metal stent (SEMS), or a transjugular intrahepatic portosystemic shunt (TIPS), are available in cases of resistant variceal bleeding that cannot be controlled with endoscopic therapies. Gastric varices have a lower incidence than esophageal varices, but bleeding from gastric varices is associated with higher mortality and morbidity rates. The first-line treatment, as with esophageal variceal bleeding, is stabilization of the patient. After that, control of bleeding can be attempted. Optimal management of gastric variceal bleeding is not yet standardized due to diverse underlying pathologies and the lack of large, randomized controlled trials. Among endoscopic techniques, endoscopic variceal obturation (EVO) has been acknowledged as reliable. Among rescue therapies, balloon-occluded retrograde transvenous obliteration (B-RTO) of gastric varices and TIPS are the most common techniques. (Acta gastroenterol. belg., 2018, 81, 305-316).
