A Small Bowel Follow Through (SBFT) is a radiologic procedure used to visualize and evaluate the small intestine's structure and function. It's a type of fluoroscopy that employs a special form of X-ray imaging, coupled with the use of a contrast material—usually barium sulfate—which the patient ingests orally. The barium helps to highlight the small intestine, allowing the radiologist to see and assess it in more detail.
The primary reason to have an SBFT is to diagnose issues related to the small intestine. These could include abnormal growths, ulcers, polyps, diverticuli, blockages, or abnormalities in the intestinal wall. It's also an invaluable tool for diagnosing conditions like Crohn's disease, celiac disease, or gastrointestinal bleeding.

During an SBFT, you will be asked to drink a contrast material (usually a barium solution). X-ray images will then be taken at regular intervals to track the barium's progress through the small intestine. The procedure usually takes 1 to 4 hours, depending on how quickly the barium moves through your system.
An SBFT is vital for diagnosing conditions and abnormalities related to the small intestine that may not be visible with other diagnostic procedures. It helps to visualize the structure and function of the small intestine clearly, aiding in accurate diagnosis and treatment planning.
The SBFT procedure is generally painless. However, you may feel some discomfort due to the fasting period before the test or the taste of the barium solution. The X-ray itself does not cause any pain.
The risks associated with SBFT are minimal. There's a small risk of radiation exposure, but the amount of radiation used is generally safe. Some people may have a minor allergic reaction to the barium contrast material, causing symptoms like itching or hives, which are usually easily treatable.
Your doctor will recommend an SBFT if you're showing symptoms or have a condition that requires investigation of the small intestine. Symptoms might include unexplained abdominal pain, blood in the stool, unexplained weight loss, or changes in bowel habits.
The frequency of an SBFT is not standardized like regular screenings; it's performed based on medical necessity. Your doctor will recommend it based on your specific symptoms and medical history.
If you experience any complications or have concerns following an SBFT, you should consult with the doctor who ordered the test or the radiologist who performed it. They can provide guidance based on your symptoms and test results.
No, you typically need to fast for at least 8 hours before an SBFT to ensure your stomach and small intestine are clear for the test. Your doctor will provide specific instructions based on your health and specific needs.
After an SBFT, you can usually resume your normal diet and activities. However, you may be asked to increase your fluid intake to help eliminate the barium from your system. If the barium is not entirely eliminated, it can harden in your bowels, leading to constipation or an obstruction.
An SBFT can identify abnormal growths or masses in the small intestine, which could be indicative of cancer. However, other tests are often needed to confirm a diagnosis of cancer.
SBFT is a valuable diagnostic tool that allows doctors to clearly visualize the small intestine and diagnose various conditions. It's a generally safe and painless procedure with minimal risks. However, proper preparation is vital for the procedure's success. Always ensure to follow your doctor's instructions carefully and discuss any concerns or questions you may have before the procedure.
