[Treatment of anorexia nervosa in both an inpatient and outpatient setting: benefits of family therapy].

Anorexia nervosa is characterized by an important morbidity, with somatical and psychological complications. This article explains the collaboration of two university units, one in hospital, the second in an ambulatory psychotherapeutical programme. The two of them work with a systemic approach, which has largely proved its efficiency in anorexia nervosa. The authors describe a clinical case during which they have experienced a different way of treatment, dissociating individual hospitalisation and family therapy. This sort of intervention requires a close collaboration between all interveners.
