Crohn’s disease (CD) is the fundamental protagonist of so-called Infl ammatory Bowel Disease (IBD). This is a term by which several entities are known. Its origin is multifactorial. It is characterized by chronic and recurrent infl ammation with different degrees of involvement of the gastrointestinal tract, but also with potential commitment of other organs. In the last decade there has been a renewed interest in these entities due to a boom in innovative medicines. Despite these medications, CD and IBD remain incurable. The increasing incidence of CD in our country requires us both scientifi cally and morally to develop basic, practical guidelines with checklists adapted to our environment for the diagnosis and management of CD through the fi rst consultations of patients.
