Radiation enteritis care at Mayo Clinic
Mayo Clinic experts work as a team to provide whole-person care to those with radiation enteritis.
Diagnosis at Mayo Clinic
Mayo Clinic specialists review your medical history and perform a physical exam to better understand your condition.
Additional tests and procedures may be used to understand the extent of your radiation enteritis, including:
- Endoscopy. During an endoscopy, a long, thin tube is passed down your throat and into your esophagus. The tube is equipped with a camera. Endoscopy allows examination of your stomach and the beginning of your small intestine.
- Colonoscopy. During a colonoscopy, a long, thin tube is passed through your rectum and into your colon. The tube is equipped with a camera. Colonoscopy can uncover changes in the colon and areas of inflammation.
- Capsule endoscopy. During a capsule endoscopy, you swallow a pill-sized camera that takes pictures as it passes through your digestive system. A capsule endoscopy allows for the inspection of the small intestine, which is difficult to access with other tests, such as endoscopy and colonoscopy.
- Enteroscopy. During enteroscopy, a camera-equipped scope reaches deeper into your small intestine to look for signs of radiation enteritis.
- CT and MRI. These imaging tests may show changes in your small intestine that suggest radiation enteritis. CT and MRI are usually done before a capsule endoscopy.
Treatment at Mayo Clinic
Radiation enteritis often is temporary. Your symptoms may subside in the weeks after your treatment ends. During this time, treatments may help relieve your symptoms. If radiation enteritis persists, other treatments may be recommended.
If you experience symptoms of radiation enteritis, your health care provider may recommend:
- Anti-diarrheal medications
- Dietary changes, such as reducing your intake of dairy products, fatty foods and high-fiber foods
- Pain medications to relieve pain of inflammation
Radiation enteritis that persists after treatment or that develops months or years after treatment is called chronic radiation enteritis. Treatment for chronic radiation enteritis is similar to treatments used for temporary radiation enteritis but may also include:
- Nutritional support. Inflammation in your small intestine may reduce your body's ability to absorb nutrients from the foods you eat. Nutritional support in the form of tube feeding (home enteral nutrition) or infusions of nutrients into a vein (home parenteral nutrition) may help make sure you get the energy and nutrients you need.
- Antibiotics. Inflammation caused by radiation may lead to a bacterial overgrowth in the small intestine that may result in bloating and diarrhea. Bacterial overgrowth can occur if the bacteria that typically live in the large intestine grow in the small intestine. Antibiotics can control bacterial overgrowth.
- Surgery. In rare cases, surgery may be needed to remove the affected intestine or to construct a way for waste to avoid that section. Because surgery carries a risk of complications, it is generally used only when other treatments don't work.
