Jejunoileitis refers to inflammation in both the jejunum and ileum, parts of the small intestine. This condition is often associated with Crohn's disease, which is an inflammatory bowel disease that can cause inflammation anywhere in the digestive tract. Some common synonyms for jejunoileitis include enteritis, small bowel inflammation, and ileitis. In addition, more specific terms may be used depending on the specific location and severity of the inflammation, such as proximal small bowel inflammation, terminal ileitis, and acute or chronic enteritis. Identifying the specific type of inflammation may be important for proper diagnosis and treatment of this condition.
