title: [Is end stage renal disease a poor prognosis factor of ischemic colitis?].
abstract: OBJECTIVE
  In general, ischemic colitis has a very good prognosis. However, there are a lot of controversies in relation to the prognostic factors. The aim of this study was to evaluate risk factors of severe ischemic colitis.
  
  
  METHODS
  A retrospective study was undertaken of patients with ischemic colitis hospitalized at the Hanyang University Hospital during the interval 2004-2006. Patients were divided into two groups: those with mild course and those with severe course which led to operation, systemic inflammatory response syndrome, or death.
  
  
  RESULTS
  A total of 41 cases (M/F=13/28, mean age=63.8 years) of biopsy proven ischemic colitis were included, of which 31 (75.6%) had a mild course and 10 (24.4%) a severe course. Coexisting medical diseases of patients were hypertension (n=24), diabetes (n=14), end-stage renal disease (n=11), cardiovascular disease (n=5), and malignancy (n=5). Male (p=0.049), alcoholics (p=0.025), end-stage renal disease (p=0.013), LDH (p=0.002), CRP (p=0.014), and peritoneal irritation sign (p=0.001) were the significant risk factors of severe ischemic colitis in univariate analysis. In multivariate logistic regression analysis, end-stage renal disease (p=0.026) was the only significant risk factor of severe ischemic colitis.
  
  
  CONCLUSIONS
  Careful attention must be paid to end-stage renal disease patients having ischemic colitis.
