Sonographic Findings in Ischemic Colitis in 58 Patients

Abstract

Sonography is a valuable technique for the detection of colonic abnormalities resulting from ischemic colitis. In this study, altered pericolic fat or the absence of improvement in sonographic follow-up studies were factors associated with transmural necrosis.

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] . Sonography may provide data for identifying patients who will develop necrosis.…”

“…Pulsed Doppler obtaining an arterial or venous signal at the location of the colour pixel should be used when there is doubt, to confirm that colour signals are originated from blood vessels and not from movement artefacts [31,33,36,37].…”

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

“…[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.…”

“…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.…”
