Bowel wall thickening: differentiation of inflammation from ischemia with color Doppler and duplex US.

Abstract

Duplex and color Doppler flow US are helpful in differentiation between ischemic and inflammatory bowel wall thickening.

Ischemic colitis: Clinical practice in diagnosis and treatment

“…Location and length of the involved colonic segment, colon wall thickening, bowel wall stratification and abnormal echogenicity of the pericolic fat and peritoneal fluid are some of the findings on sonography [41] . Color Doppler sonography may be useful in the differentiation between inflammatory and ischemic bowel wall thickening [42] .…”

Ischemic Colitis: Surging Waves of Update

“…Doppler techniques are particularly useful for investigating chronic mesenteric ischemia. Limitations of Doppler analysis of celiac artery and SMA ischemia include that (1) the great potential for collateralization in the splanchnic vessels may make an assessment of a singlevessel stenosis difficult, (2) the risk of error increases when the angle of insonation is greater than 60° and (3) careful placement of the sample volume is crucial (Teefey et al 1996;Dirkx and Gerscovich 1998).…”

Bowel obstruction as a result of ischemic colitis: Review of literature with contribution of one case report

“…Sometimes, at the anteroposterior X-rays can be found some non-specific signs as loss of haustration and dilation of colon -Irigography -it registers the indirect changes as ulcers and sulci on the mucous membrane, edema and strictures -The computed tomography is one of the methods, that enable the determination of the colonic hypoperfusion (Balthazar et al, 1999;Jones et al, 1982) -Abdominal echography and endolumen echography -they enable differentiating of the inflammatory from ischemic stenoses of the intestinal lumen (Teefey et al, 1996) -Colonoscopy is the most precise and sensitive method for the disease identification. It allows visualization and taking of biopsy of the significant mucous membrane changes.…”
