How long does a small bowel follow-through take? This is a common question among patients undergoing this diagnostic procedure. A small bowel follow-through, also known as a barium enema, is a radiographic examination that involves the use of barium sulfate to visualize the small intestine. The duration of the procedure can vary depending on various factors, which we will explore in this article.
The small bowel follow-through procedure typically begins with the patient being positioned on an X-ray table. The radiologist or technician will then insert a catheter into the rectum, through which the barium sulfate will be administered. The time it takes to complete this part of the procedure usually ranges from 15 to 30 minutes.
After the barium sulfate has been administered, the patient will be asked to change positions several times to ensure that the barium coats the entire small intestine. This process can take anywhere from 30 minutes to an hour, as the patient must wait for the barium to move through the digestive tract.
Once the barium has reached the small intestine, X-rays will be taken at regular intervals to monitor its progress. The number of X-rays taken can vary, but on average, this part of the procedure takes between 30 minutes to an hour. During this time, the patient may be asked to hold their breath or move into specific positions to help the radiologist capture the best images.
After the X-rays have been taken, the patient will be asked to wait for a short period to allow the barium to pass through the digestive tract. This waiting time can range from 1 to 2 hours, depending on the individual’s digestive speed and the amount of barium used.
Finally, the patient will be asked to return for a follow-up appointment to have additional X-rays taken. This appointment is necessary to ensure that the barium has completely passed through the small intestine and that no abnormalities are present. The follow-up appointment usually takes about 15 to 30 minutes.
In summary, the entire small bowel follow-through procedure, from start to finish, can take anywhere from 2 to 4 hours. However, this time can vary depending on the individual patient’s situation and the specific instructions given by the radiologist. It is important for patients to follow the pre-procedure instructions provided by their healthcare provider to ensure the best possible results and minimize any discomfort during the examination.
