Abstract
Vascular lesions of the colonic mucosa were studied endoscopically in 37 patients with portal hypertension. The characteristic findings of colonoscopy in these patients and their incidence rates were : vascular ectasia, 62.6 % ; dilated fine branching vessel, 86.5% ; blue vein, 51% : and rectal varices, 21.6%. We studied the relation of the prevalence of each finding to the degrees of esophageal varices, Child-Pugh classification and ICG R15 value. There was a tendency that vascular ectasia was found in patients with advanced esophageal varices of F2 and F3. The various findings of biopsy specimens in these patients and their incidence rates were : mucosal congestion, 51.4% ; mucosal edema, 32.4% ; and mucosal or submucosal dilated capillaries, 16.2%. No remarkable change in endoscopic findings of the colon was observed after the endoscopic injection sclerotherapy (EIS).
