“…Ultrasound is a noninvasive imaging-based examination and is sensitive to the early structural changes in colonic walls caused by ischemia. Lopez et al [41] found that the positive predictive value (PPV) of abdominal ultrasound in detection of IC was 87.5%. A retrospective study reported that the predictive model consisting of sonographic features and clinical findings could accurately predict the outcomes of IC affliction and distinguish properly between patients with mild and severe cases of IC [42].…”

Purpose Ischemic colitis (IC) is the most prevalent ischemic injury of thegastrointestinal tract. Clinical features of IC such as acute abdominal pain, hematochezia,and diarrhea are similar to those of acute mesenteric ischemia, inflammatorybowel disease, or infectious bowel disease, and their relative ambiguity candelay diagnosis and treatment. To comprehensively detail the current state ofdiagnostic methods and available drug therapies for detecting and treating IC,this review aims to provide a concise and practical summary of thecorresponding literature. Methods PubMed and Cochrane Library were searched toretrieve all published studies reporting the diagnostic methods and drugtherapies in patients with ischemic colitis. The search strategy of drugtherapy includes human and animal data. Results Colonoscopy combined with histopathologicalbiopsy is the standard of diagnosis for the IC. Most patients respond well tothe conservative treatment, and surgical consultation is needed when conservativetreatment is ineffective. Studies of potential drug therapy have beendeveloped, including phosphodiesterase type 5 inhibitors, pentoxifylline,rebamipide, prostaglandin E1, and polydeoxyribonucleotide. Conclusion Accurate diagnoses and effective treatmentshave helped reduce the mortality rate and improve prognoses for patientsafflicted with IC, and corresponding drug therapies have been constantlyupdated as new research has emerged.

“…Ultrasonography, a non-invasive and readily available test, has the ability to detect mural thickening of the colon and suggests this pathology in patients with abdominal pain. Therefore, parietal thickening of a segment of the large bowel with a length of more than 10 cm, in a symptomatic patient with advanced age (>50 years), is a strong indication for IC ( 60 ). According to Lopez et al, abdominal sonography has a high positive predictive value in detecting IC (PPV 87.5%).…”

“…However, ultrasonography cannot detect intestinal pneumatosis, which is detectable by the CT imaging. Moreover, CT is preferable than ultrasound in identifying cases of IC after AAA repair, since the colonic wall is often not thickened in these cases and the diagnosis is made in the absence of contrast enhancement of the diseased colon ( 60 ).…”

BackgroundIschemic colitis (IC) is a common type of ischemic insult, resulting from decreased arterial blood flow to the colon. This disease can be caused from either atherosclerotic occlusive vascular disease or non-occlusive disease. The aim of this study is to present the diagnostic methodology and management of this severe disease based on current literature.MethodsA literature search has been done including articles referring to modern diagnosis and management of IC.ResultsIC is usually a transient disease, but it can also cause gangrene of the colon, requiring emergency surgical exploration. Diagnosis is troublesome and is based on imaging examinations, mainly computerized tomography, which in association with colonoscopy can delineate the distribution pattern and severity of disease.ConclusionThe majority of patients with mild disease have usually complete clinical recovery within a short period. The severe forms of the disease carry high morbidity and mortality rates and prompt surgical intervention is the only way to improve the associated severe prognosis.
