Upper GI and small bowel series

Upper GI and Small Bowel Series: An Overview

Upper gastrointestinal (GI) and small bowel series are imaging tests used to examine the organs in the upper part of the gastrointestinal tract. This imaging diagnosis involves the use of a series of X-rays, or radiographs, to create detailed pictures of the upper GI system, including the esophagus, stomach, small intestine, and sometimes the lower portion of the large intestine. Doctors may order this test to identify diseases and disorders of the upper GI system, such as ulcers, tumors, and abnormal restrictioning of the intestinal wall.

Preparation for a Small Bowel Series

Prior to a small bowel series, you should tell your doctor about any medical conditions you have and any medications you are taking. Your doctor will tell you if any of your medications need to be stopped before the test. You may also be asked to fast for 4 to 8 hours before the procedure. It is important to follow your doctor's instructions closely to ensure accurate results.

Procedure for a Small Bowel Series

For the small bowel series, you will be asked to lay on a table and swallow a contrast material, usually a barium solution. This barium highlights your digestive tract on the X-ray. The radiologist may ask you to move in different positions, such as lying on your side or bending over, to help create the desired X-ray images. You will then be asked to urinate and the radiologist will be able to observe the flow of barium through the digestive tract. The procedure will take between 30 minutes to 1 hour. You will be able to resume your normal activities after you have finished the procedure.

Types of Small Bowel Series

There are two types of small bowel series: standard and double-contrast. The standard series involves taking X-rays after you have taken the contrast material (barium) and waiting one hour for the material to move through the entire digestive tract. The double-contrast series involves taking X-rays at the beginning of the procedure and one hour later. This procedure allows for the radiologist to view any subtle changes that have occurred in the digestive tract during the hour.

Risks of a Small Bowel Series

The risks of a small bowel series are minimal and usually involve some mild discomfort. Some people may experience nausea or cramping during or after the procedure. You may also feel bloated or gassy from swallowing the barium solution. Additionally, the barium can cause constipation and dehydration, which can be avoided by drinking plenty of fluids after the procedure.

Why is a Small Bowel Series Done?

A small bowel series may be ordered if the doctor has concerns about the digestive tract, such as an obstruction, inflammation, or cancer. It is also commonly used to diagnose Crohn's disease and ulcerative colitis. Additionally, the test can be used to evaluate the effectiveness of treatments, such as medications and surgically placed stents.

When is a Small Bowel Series Done?

A small bowel series may be ordered if the doctor has concerns about the digestive tract, such as an obstruction, inflammation, or cancer. It can also be used to determine the presence of small intestine diseases, such as Crohn’s disease or ulcerative colitis. It can also be used to evaluate the effectiveness of treatments or to detect abnormalities that can be caused by birth defects or trauma.
