Radiation enteritis

  • Alternative Names

    Radiation enteropathy; Radiation-induced small bowel injury; Post-radiation enteritis


    Newer treatment methods are used, when possible, to avoid or decrease the chance of radiation enteritis. These methods include:

    • Adjusting how much radiation is given during any one treatment session, so that lower amounts are delivered more evenly or higher amounts are delivered to specific areas
    • Having a full bladder during treatments
    • Placing special clips surgically around the area needing radiation. This helps the radiation doctor focus on the treatment area.
