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

Abdomen and pelvis CT scan (with intravenous contrast and oral water soluble contrast) can also distinguish early postoperative ileus from mechanical obstruction. In addition, CT scan can also identify other complications seen in post-operative period or ileus related complications, such as perforation, strangulation and necrosis. Findings on CT scan diagnostic of postoperative ileus include:[1][2][3]
- Multiple air–fluid levels throughout the abdomen
- Elevation of diaphragm
- Dilation of both large and small intestine
- No transition zone (specially between small and large intestine)
- No evidence of mechanical obstruction
