Anorectal varices in portal hypertension have been little studied: Seventy eight per cent of 72 patients with portal hypertension had anorectal varices shown at flexible sigmoidoscopy. Significantly more patients with noncirrhotic portal hypertension had these varices than patients with cirrhosis (89% v 56%, p less than 0.01).
