Brisk Hematochezia in Cirrhosis

61 year old male with alcohol-related cirrhosis presents with severe ascites. He had a therapeutic paracentesis with improvement in his ascites and underwent a surveillance EGD which showed large varices that were then banded. The following day, he developed tachycardia, hypotension, and hematochezia. A nasogastric tube was placed to suction without blood return.
