Can CT scan miss intestinal blockage?

CT is reported to have a sensitivity of 78%-100% for the detection of complete or high-grade small bowel obstruction but may not allow accurate diagnosis in cases involving incomplete obstruction.

What can an abdominal CT scan miss?

Those studies found that the most frequent misses on the abdominal CT are in the vascular system (blood clots), the bowel, the musculoskeletal system, and the body wall.

What is the best imaging for intestinal obstruction?

Computed tomography is usually the most appropriate and accurate diagnostic imaging modality for most suspected bowel obstructions.

Can a partial bowel obstruction be missed on CT scan?

The reported sensitivity of CT scanning for detecting small-bowel obstruction is 78-100% in high-grade or complete obstruction. If the obstruction is partial or intermittent, the accuracy is low.

How do you rule out a bowel obstruction?

Can CT show small bowel obstruction?

Multidetector computed tomography (CT) is a powerful tool for the assessment of patients with small bowel obstruction (SBO). CT can provide important information about the cause and site of obstruction and the presence of a closed-loop obstruction or ischemia.

What does a colonoscopy show that a CT scan doesn t?

The four cardinal symptoms of bowel obstruction are pain, vomiting, obstipation/absolute constipation, and distention. Obstipation, change in bowel habits, complete constipation, and abdominal distention are the predominant symptoms in LBO.

Will a CT scan with contrast show bowel obstruction?

In clinical studies, CT with contrast has proven the most versatile in assisting in these diagnostic aspects of intestinal obstruction. Peck et al. studied 55 patients having both computed tomography and small bowel follow-through studies to evaluate possible small bowel obstruction.

Can you see bowel inflammation on CT?

A CT scan will identify inflamed diverticula, bowel wall inflammation, pericolic fat stranding, and corresponding complications [9,10,11,83,87,88]. CT is capable of visualizing pericolonic and colonic complications which results in a more accurate diagnosis for the patient, along with better standard of care.

Do you need contrast for CT for bowel obstruction?

In conclusion, evidence-based literature suggests that CT for suspected SBO should be performed with IV contrast whenever possible. Oral contrast does not provide benefit and may cause harm.

Can an intestinal blockage clear itself?

Most of the time, complete blockages require a stay in the hospital and possibly surgery. But if your bowel is only partly blocked, your doctor may tell you to wait until it clears on its own and you are able to pass gas and stool.
