We studied blood ammonia levels regarding the presence of endoscopic risk signs for esophageal varix bleeding, and we noted that the mean blood ammonia was significantly higher among patients having one or more of these endoscopic signs than in patients having none of them (p=0.009) (Table 2).
Occurrence of discrete large varix with no other source of hemorrhage and with no evidence of esophageal varices.8

Using a micropuncture kit, the peristomal varix was directly accessed under ultrasound guidance and a micropuncture sheath was placed.
We describe another case of HPVG that is associated with peptic ulcer disease in which we hypothesize that the ulcer might have allowed the entrance of luminal gas and fungus into an enlarged mesenteric varix. We also demonstrated the resolution of HPVG following treatment of the gastric ulcer with an intravenous proton pump inhibitor and bowel rest.

Although lamellae in Nucella lamellosa resemble axial varices in other muricid shells, and a growth hiatus is typically observed after completion of a varix (MacKenzie, 1961; Inaba, 1967; MacGinitie and MacGinitie, 1968; Spight et ai, 1974; Spight and Lyons, 1974; Illert, 1981), we observed no evidence of a growth hiatus after completion of a lamella.
(5,6) The differential of renal varix includes renal or urothelial neoplasm, hemangioma, blood clots, pyelo-ureteritis cystica, leukoplakia, tuberculosis, and radiolucent calculi.
Grade II: Protrusion of the varix, but not more than half way to the center of the lumen.
They were divided into three groups: (1) the portal hypertensive gastropathy group--203 patients with esophageal varices (EV) and PHG, (2) the esophageal varix group--41 patients with EV but no PHG, and (3) the control group--137 patients with no EV or PHG.
Early recurrent bleeding (within 5 days) can be observed in nearly 8%-20% of patients with cirrhosis and is associated with a high risk for death, particularly in patients with a high hepatic venous pressure gradient and fibrotic varix caused by previously repeated banding (1).
