Neutropenia after induction or consolidation therapy for acute myeloid leukemia (AML) patients is associated with a high morbi-mortality rates, especially due to infectious complications. These are managed according to international recommandations (ECIL and IDSA) with antibiotherapy and antifungal strategy. Although the patients suffer of digestive symptoms, intestinale complications are really less explored. Neutropenic enterocolitis (NE), cytomegalovirus (CMV) colitis, Clostridium difficile colitis, specific lesion, ischemic colitis are not well-known. No prospective study evaluate NE and these digestive complications which have high morbi-mortality rates.
