An appropriated anamnesis and laboratorial analysis are the most frequent and feasible used tools. The aim of this study was to evaluate the role of these practices in IgE mediated CMA...

Emergency laparotomy could be effective treatment, but the prognosis remains poor related to the hepatic reserve.
