Accurate diagnosis of small bowel obstruction is essential for effective treatment. Let's explore the tests that can help identify this condition.

Initial Imaging Techniques

Doctors often start with plain radiographs, or X-rays, to get a quick look at the abdomen. These can reveal dilated loops of bowel and air-fluid levels, suggesting an obstruction. While not always definitive, they offer a first glimpse into the problem.

Advanced Diagnostic Tools

For a more detailed view, a CT scan of the abdomen is generally used. This can show the exact location and severity of the obstruction, as well as any complications like ischemia. CT scans are highly accurate and provide valuable information for planning treatment.

Alternative Options

In cases where CT scans are not suitable, such as in pregnant women or those allergic to contrast, ultrasound or MRI can be alternatives. While these methods might not be as detailed as a CT scan, they still offer reliable diagnostic information.
