An abdominal and pelvic<unk>  scan is used to confirm the diagnosis of postoperative<unk>  only in cases when an x-ray is not diagnostic. An abdomen and pelvis<unk>  scan (with intravenous contrast and oral water soluble contrast) can also distinguish early postoperative<unk>  from mechanical obstruction. In addition, a<unk>  scan can also identify other complications seen in the post-operative period or<unk>  related complications, such as perforation, strangulation and necrosis. Findings on a<unk>  scan diagnostic of postoperative<unk>  include multiple air–fluid levels throughout the abdomen, elevated diaphragm, and dilation of both large and small intestine with no evidence of mechanical obstruction.
