Sonographic detection of longitudinal ulcers in Crohn disease

Abstract

Ultrasonographic findings of FD sign are correlated with the existence of deep longitudinal ulcers, which are most frequently found in CD. US is a useful diagnostic modality for detecting longitudinal ulcers in patients with CD.

Prospektiver Vergleich von Power-Dopplersonographie und Ileokoloskopie in der Aktivitätsbewertung bei Patienten mit Morbus Crohn

The usefulness of transabdominal ultrasound for the diagnosis of lower gastrointestinal bleeding

“…Small bowel bleeding was diagnosed in two of the patients in whom no bleeding source was detected by colonoscopy. A diagnosis of 12,16,17 Ischaemic colitis 12,19,20 Infectious colitis 13,18 Crohn's disease 12,13,16,20,23 Colorectal cancer 14 Normal perigut fat small bowel bleeding is generally made when fresh blood is found in the terminal ileum or coming through the ileocaecal valve and results of upper GI endoscopy are negative. The definite diagnoses in the 90 patients mentioned above included ischaemic colitis (n ¼ 23), ulcerative colitis (n ¼ 12), haemorrhoid (n ¼ Table 2).…”

“…Inflammatory bowel disorders, such as ulcerative colitis, Crohn's disease, diverticulitis, infectious colitis and ischaemic colitis, produce mucosal inflammation, erosions and ulcer of various intensities in different bowel areas. [12][13][14][15][16][17][18][19][20][21][22][23] Because it is radiation free, non-invasive and costeffective, we commonly perform US in patients with abdominal complaints. A great advantage of US is that it can be performed at any time without bowel preparation, and the colon is easily depicted by sonography.…”

“…[12][13][14][15][16][17][18][19][20][21][22][23] Transabdominal ultrasound (US) is a non-invasive and repeatable imaging study that can be performed easily without bowel preparation. The purpose of this study was to evaluate the usefulness of US for diagnosing lower GI bleeding.…”

Ultrasonographic Diagnosis of Colitis

“…Ultrasonographic features of colitis have been reported for Crohn's disease, ulcerative colitis, ischemic colitis, pseudomembranous colitis, bacterial colitis, Behçet's disease, collagenous colitis, lymphocytic colitis, amebic colitis, small bowel involvement of adult Henoch-Schonlein purpura, and neutropenic enterocolitis, etc. (1)(2)(3)(4)(5)(6)(7)(8)(9)(10)(11)(12)(13)(14). When gray-scale US is used, the basic and important findings for the differential diagnosis of colitis are bowel wall thickness and echotexture.…”
