A bowel ultrasound, also known as a transabdominal ultrasound, is a non-invasive imaging procedure used to evaluate the gastrointestinal (GI) tract. It employs sound waves to produce detailed images of the bowel and surrounding structures, helping diagnose and monitor various bowel-related conditions.

Bowel Ultrasound (Transabdominal Ultrasound)

Bowel ultrasound is a diagnostic imaging technique that uses high-frequency sound waves to visualise the intestines and adjacent organs. The procedure is performed by placing an ultrasound probe on the abdomen, which sends sound waves into the body. These waves are reflected back and converted into real-time images displayed on a monitor.

It is particularly effective in assessing the walls of the bowel and detecting inflammation, thickening, or other abnormalities.

Why Do You Do This Procedure?

This procedure is performed to:

• Detect and assess inflammation in the bowel caused by conditions such as Crohn’s disease or ulcerative colitis.
• Identify structural abnormalities, such as strictures, fistulas, or bowel wall thickening.
• Monitor disease progression or response to treatment in patients with chronic bowel conditions.
• Evaluate unexplained abdominal pain, changes in bowel habits, or other GI symptoms.
• Rule out complications such as abscesses or obstructions.

Bowel ultrasound is preferred in many cases due to its safety, lack of radiation exposure, and ability to provide real-time visualisation.

When Does This Procedure Happen?

A bowel ultrasound is typically recommended:

• When inflammatory bowel disease (IBD) is suspected, based on symptoms such as chronic diarrhoea, abdominal pain, or weight loss.
• During flare-ups of existing bowel conditions to assess the extent of inflammation or complications.
• As part of follow-up care to monitor treatment effectiveness or disease progression.
• In patients with non-specific abdominal symptoms requiring further evaluation.

The procedure may be scheduled in conjunction with other diagnostic tests, such as blood tests, stool studies, or colonoscopy, to provide a comprehensive assessment.

What Condition Does This Treat?

While bowel ultrasound itself is a diagnostic tool rather than a treatment, it plays a crucial role in the management of conditions such as:

• Inflammatory bowel disease (Crohn’s disease and ulcerative colitis): To detect active inflammation or complications.
• Irritable bowel syndrome (IBS): To rule out structural abnormalities.
• Bowel obstructions: To identify the cause and severity.
• Bowel infections or abscesses: To detect and localise affected areas.
• Diverticulitis: To evaluate inflammation and complications.
