Abstract
Ischemic colitis (IC) is a frequent disorder in older person but it is usually self-limiting disease responding to conservative treatment. Recently, incidence of IC increase in gradual at broad range of age, especially to young age, relatively. The aims of this study are to evaluate clinical characteristics of patients with IC treated in Chonnam National University Hospital (CNUH). Between January 2000 and May 2007 in CNUH, 67 patients (30 males, 37 females) with IC were enrolled. We compared clinical features between young and elderly, group with IC accompanied with constipation, irritable bowel syndrome (IBS), or not. Among the 67 IC patients, most patients (79.1%) are older than fifty years and suffer from abdominal pain (71.6%), hematochezia (59.7%) and diarrhea (38.8%). Most of all are diagnosed through colonoscopy (79.1%) or abdominal CT (65.6%) and recovered by conservative treatment (89.6%). Risk factors for IC are atherosclerotic vascular diseases (56.7%), vasoactive medicine (31.3%), IBS (11.9%) and constipation (13.4%). Older age with IC has more frequently associated with risk factors. At the comparison associated with IBS, 3 patients (37.5%) with IBS and 4 patients (6.8%) without IBS have surgery (p=0.008). At the comparison associated with constipation, 45 patients (77.6%) without constipation and 3 patients (33.3%) with constipation have abdominal pain. The results suggest that the presence of IBS or constipation may not be associated with frequency or severity of IC. But more large scaled epidemiologic study was needed.
