Extraintestinal manifestations of idiopathic ulcerative colitis

One hundred and fifty patients of idiopathic ulcerative colitis were studied for extraintestinal manifestations by clinical, radiological and biochemical means. One or more such manifestations occurred in 34.7% of patients. Sacroiliitis (14%) and peripheral arthritis (10.7%) were the commonest manifestations, followed by ocular (8%), mucocutaneous (2.7%), vascular (2%) and hepatobiliary (1.3%) manifestations. We conclude that the incidence and spectrum of extraintestinal manifestations in Indian patients with idiopathic ulcerative colitis are similar to those in western patients.
