A randomized trial of endoscopic treatment of acute gastric variceal hemorrhage: N-butyl-2-cyanoacrylate injection versus band ligation. Introduction: The first-line treatment for gastric variceal rebleeding in cirrhotic patients is endoscopic cyanoacrylate injection. BACKGROUND AND PURPOSE: Endovascular treatment of wide neck aneurysms often results in incomplete occlusion or aneurysm recurrence. The tissue glue, N-butyl-2-cyanoacrylate, is a watery solution that polymerises and hardens within 20 s in a physiological milieu and instantaneously on contact with blood. How It Works Unlike traditional adhesives which are water-based, cyanoacrylate … Endoscopic injection of gastric varices with cyanoacrylate is effective in prevention of rebleeding. White, Jr, MD Although liquid adhesives or glue have been used as embolic agents for nearly three decades, experience with them outside of neurointerventional indications is generally limited. Conclusions: Endoscopic cyanoacrylate injection with Lauromacrogol might minimize the required dosage of cyanoacrylate, but it did not improve rebleeding rate or survival. However, there has been no clinical evaluation of its effectiveness in treating (a) (b) (c) Figure 1: A male (58 years old) duodenal DL patient received cyanoacrylate injection … injection in the vessels, cyanoacrylate glues are mixed with a contrast agent, typically an iodized poppy seed oil such as Lipiodol (Laboratoire Guerbet, Aulnay-sous-Bois, France).

Introduction Gastric varices (GV) are less commonly seen but bleed more severely than esophageal varices (EV). We designed a prospective study to compare the efficacy of endoscopic band ligation (GVL) and endoscopic N-butyl-2-cyanoacrylate injection (GVO). Transjugular intrahepatic portosystemic shunt (TIPS), alcohol injection, and N-butyl-2-cyanoacrylate (NBCA) are generally used for GV bleed management. Endoscopic injection of Histoacryl has been recommended for gastric variceal bleeding. In fact, the term cyanoacrylate glue generally describes quick-bonding super glues. This leads to obliteration of the varix from which the cast extrudes after 2–4 weeks. Cyanoacrylate injection has been used to treat hemor-rhage of esophageal varices since the late 1970s [27]. The method still poses a risk of ectopic embolism, which possibly correlates with the volume of cyanoacrylate used. In addition, if cyanoacrylate extravasates and gets stuck to the endoscope, it will cause permanent damage to its working channel. It has been recommended to use endoscopic cyanoacrylate injection as the first line treatment for hemostasis and secondary prophylaxis for gastric varices by general consensus. N-butyl cyanoacrylate is delivered via catheters or by percutaneous injection resulting in occlusion of target veins. References ↵ Sarin SK, Lahoti D, Saxena SP, et al.
