Treatment
Initial treatment of bleeding from gastric varices focuses on resuscitation, much as with esophageal varices. This includes administration of fluids, blood products, and antibiotics.
The results from the only two randomized trials comparing band ligation vs cyanocarylate suggests that endoscopic injection of cyanoacrylate, known as gastric variceal obliteration or GVO is superior to band ligation in preventing rebleeding rates. Cyanoacrylate, a common component in 'super glue' is often mixed 1:1 with lipiodol to prevent polymerization in the endoscopy delivery optics, and to show on radiographic imaging. GVO is usually performed is specialized therapeutic endoscopy centers. Complications include sepsis, embolization of glue, and obstruction from polymerization in the lumen of the stomach.
Other techniques for refractory bleeding include:
- Transjugular intrahepatic portosystemic shunts (TIPS)
- Balloon occluded retrograde transvenous obliteration techniques (BORTO)
- Gastric variceal ligation, although this modality is falling out of favour
- Intra-gastric balloon tamponade as a bridge to further therapy
- a caveat is that a larger balloon is required to occupy the fundus of the stomach where gastric varices commonly occur
- Liver transplantation

Famous quotes containing the word treatment:
“Judge Ginsburg’s selection should be a model—chosen on merit and not ideology, despite some naysaying, with little advance publicity. Her treatment could begin to overturn a terrible precedent: that is, that the most terrifying sentence among the accomplished in America has become, “Honey—the White House is on the phone.””
—Anna Quindlen (b. 1952)
“If the study of all these sciences, which we have enumerated, should ever bring us to their mutual association and relationship, and teach us the nature of the ties which bind them together, I believe that the diligent treatment of them will forward the objects which we have in view, and that the labor, which otherwise would be fruitless, will be well bestowed.”
—Plato (c. 427–347 B.C.)
“The treatment of the incident of the assault upon the sailors of the Baltimore is so conciliatory and friendly that I am of the opinion that there is a good prospect that the differences growing out of that serious affair can now be adjusted upon terms satisfactory to this Government by the usual methods and without special powers from Congress.”
—Benjamin Harrison (1833–1901)
