Lower GI series
Lower gastrointestinal series is a medical procedure used to examine and diagnose problems with the human colon. This procedure is also known as a barium enema, because it involves filling the colon with a liquid that contains the chemical element barium.
Procedure[edit | edit source]
The patient is first given a laxative or an enema to clean out the colon. Then, a small tube is inserted into the rectum, and the colon is filled with a liquid that contains barium. This liquid helps to coat the lining of the colon, making it easier to see on an X-ray.
The patient is then moved into different positions and X-ray images are taken from different angles. These images can show problems such as polyps, diverticula, or cancer.
Uses[edit | edit source]
A lower GI series can be used to diagnose a variety of conditions, including:
- Colon cancer
- Diverticulosis and diverticulitis
- Polyps
- Ulcerative colitis and Crohn's disease
- Bowel obstruction
Risks[edit | edit source]
As with any medical procedure, there are some risks associated with a lower GI series. These can include:
- Allergic reaction to the barium
- Infection
- Perforation of the colon
- Radiation exposure
