Two Cases of Gastric Varices Developing after Endoscopic Variceal Ligation for Esophageal Varices

We reported two patients who developed gastric varices immediately after endoscopic variceal ligation for esophageal varices, although pretreatment endoscopical examination had revealed no sign of gastric varices. In both cases angiography and computer tomography failed to demonstrate portocavanal shunts including gastrorenal shunt. Following successful treatment with endoscopic injection sclerotherapy using ethanolamine oleate, ethanol and cyanoacrylate, para-esophageal colateral veins developed and was demonstrated either by angiography or computer tomography. These observations suggest that gastric varices can easily occur after the abrupt occlusion of esophageal varices in cases in which para-esophageal colateral veins have previously not existed. Postoperative development of such shunts, therefore, may reduce the possibility of recurrence through decompression of portal blood pressure
