Facing Terminal Ileitis: Going Beyond Crohn's Disease

Terminal ileitis (TI) is an inflammatory condition of the terminal portion of the ileum that may occur acutely with right lower quadrant pain followed or not by diarrhea, or exhibit chronic obstructive symptoms and bleeding and normally it is associated to Crohn's disease (CD) although it may be associated to other different conditions. This review intended to contribute to a better understanding of TI in order to help in the diagnosis, medical approach and patient care. This work was performed on a survey of articles collected in different databases and a retrospective search was carried out to identify relevant studies in the field. Pathological conditions such as ulcerative colitis, the intake of non-steroidal anti-inflammatory drugs, infectious diseases, eosinophilic enteritis, malignant diseases, spondyloarthropathies, vasculitides, ischemia, sarcoidosis, amyloidosis and others may be related to ileitis but it is commonly referred to CD. To a correct therapeutic approach, it is necessary to understand the causes of this inflammation process. The performance of a clinical, laboratory, endoscopic, and histopathological evaluation of the individuals is crucial to the correct diagnosis and treatment once the inflammation of the ileum may occur due to different pathological conditions besides CD, leading to difficulties in the diagnosis. Thus, an individual approach is necessary once the correct diagnosis is crucial for the immediate therapeutic approach and recovering of the patient.
