A small bowel follow through, also known as a small bowel series, is a medical imaging test that aids in the diagnosis of conditions affecting the small intestine. The test involves the use of fluoroscopy, which is a type of real-time X-ray, to aid physicians in observing the small intestine's structure and functionality. The procedure is typically conducted on an outpatient basis, with the patient typically lying on their back on an exam table while the imaging takes place.
During the small bowel follow through, patients typically drink a liquid containing barium sulfate, which is a contrast agent that enhances the visibility of the small intestine's inner surface on the X-rays. The barium sulfate coats the small intestine walls, allowing the fluoroscope to capture images of the organs within the small intestine. These images are then used by radiologists to assess the integrity of the small intestine and to identify any potential issues, such as blockages, strictures, or tumors.
The small bowel follow through is a valuable tool in the diagnosis of a range of conditions, including Crohn's disease, small bowel obstruction, inflammatory bowel disease, and polyps or masses in the small intestine. It can also help in detecting complications related to surgery on the abdomen or small bowel. Overall, the small bowel follow through is an essential part of evaluating the small intestine and ensuring the proper diagnosis and treatment of any associated conditions.
