title: Colonic mucosal changes in portal hypertension.
abstract: Forty one consecutive patients with portal hypertension (PHT) were evaluated by colonoscopy to study the prevalence, type, extent and predictors of haemorrhoids, colorectal varices, and portal hypertensive colopathy. Specific inquiry and regular follow-up assessed frequency of hematochezia. Twenty five patients with obscure gastrointestinal bleeding without PHT who underwent colonoscopy served as controls. Haemorrhoids were seen in nine of 41 (21.9%) patients with PHT and four of 25 (16%) controls (p = ns). Colorectal varices were seen in 13/41 (31.7%) patients with PHT and none of the controls (p = 0.005). Portal colopathy was present in 15/41 (36.6%) patients with PHT and none of the controls (p = 0.0005). None of the parameters (e.g. aetiology of PHT, Child's class, oesophageal variceal eradication by EST with or without EVL, history of variceal bleeding, grade of oesophageal varices, presence of portal hypertensive gastropathy or gastric varices) predicted the occurrence of colorectal varices and portal hypertensive colopathy. Detection of colorectal varices but not portal hypertensive colopathy was associated with occurrence of hematochezia.
