Early diagnosis of acute intestinal ischaemia: contribution of colour Doppler sonography.

The aim of this study was to evaluate the contribution of colour Doppler sonography in the diagnosis of acute intestinal ischaemia. In a two years experience, all patients admitted for acute abdominal pain in our emergency department were evaluated with colour Doppler sonography of the abdomen. The final diagnosis based on clinical evolution, endoscopic or surgical findings and further radiological investigations was compared to the sonographic results. Therapy and final outcome of the patients with acute intestinal ischaemia were also evaluated. In twenty-one patients a final diagnosis of acute intestinal ischaemia (mesenteric ischaemia (n = 13) and ischaemic colitis (n = 8)) was made. Intestinal ischaemia was correctly diagnosed by initial clinical and biological data and further confirmed by sonography in eight cases (mesenteric ischaemia (n = 2) and ischaemic colitis (n = 6)). Eleven other cases were detected by suggestive colour Doppler sonography features (mesenteric ischaemic (n = 10) and ischaemic colitis (n = 1)). Sixteen of the 21 patients had a final favourable outcome (mesenteric ischaemia (10/ 13) and ischaemic colitis (6/8)). We conclude that sonography has a place in the diagnosis of acute intestinal ischaemia and has to be integrated in the diagnostic algorithm of this acute condition. By this way, this diagnosis may be suspected earlier and may allow a prompt and adapted treatment with possible improvement in survival rate.
