Abstract
Early detection of signs of strangulation in case of acute small bowel obstruction is critical because it mandates an operation. Therefore the role of different radiological techniques used for diagnosing strangulating small bowel obstruction has been discussed here. Strangulation remains a major problem in patients with acute small bowel obstruction. Despite of having several radiological diagnostic tools, CT is the only method with established higher diagnostic sensitivity and specificity in patients with acute small bowel obstruction as well as strangulation.
Highlights
Acute small bowel obstruction is a common surgical emergency, accounts for 12-16% of all surgical admissions in patients with acute abdominal conditions.[1]
The major problem is the early detection of strangulation, which has a mortality of up to 40%

Summary
Acute small bowel obstruction is a common surgical emergency, accounts for 12-16% of all surgical admissions in patients with acute abdominal conditions.[1] Small Bowel Obstruction (SBO) is caused by variety of pathologic processes, mostly by adhesions (~60%), followed by malignancy (~20%), hernias (~10%) and Crohn disease (~5%).[2] Its diagnosis is based on carefully taken patient history, clinical examinations and radiological findings. Abdominal imaging plays an important role in the acute setting. It can indicate the site, level, degree and cause of obstruction and assess for the presence of ischemia.[3] This article presents the various imaging techniques used in establishing the diagnosis of acute small bowel obstruction
