Abstract
Background/Aims
Although the majority of ischemic colitis have excellent prognosis by supportive management, there are a lot of controversies in relation to the prognostic factors. Lately, role of sonography has been emphasized in colonic ischemia. The aim of this study is the identification of the prognostic factors and the usefulness of high-resolution ultrasonography in detecting involved site and severity of ischemic colitis. Methods: The clinical databases were reviewed between April 1999 and March 2004. 60 cases were diagnosed as ischemic colitis. Clinical characteristics, coexisting illness, segment of colon involved, and sonographic finding were analyzed. Results: The poor prognosis group was significantly older than the good prognosis group (p=0.017). The difference in involved colonic segment between the two groups was statistically significant (p=0.001). However, in logistic regression, only right colonic involvement was an independent poor prognostic factor (95% confidence interval, 1.7-46.4; p=0.01). Ultrasonography had a sensitivity of 85% and a specificity of 82%. Conclusions: Only right colonic involvement was an independent poor prognostic factor. Noninvasive high-resolution ultrasonography was a valuable technique for the detection and the follow-up of colonic ischemia. Therefore, sigmoidoscopy and sonography are preferable to heavy going colonoscopy in severe colonic ischemia. (Intestinal Research 2006;4:32-38)
