Neutropenic enterocolitis in the child with cancer: our casuistics and review of the literature

Abstract

Background: Neutropenic enterocolitis or thyphlitis is a lesion of the ileocecal arca with lack of inflammatory or tumoral infiltration and different degrees of affection on the bowel wall. It is typical in patients with hematologic malignancies with prolonged or severe neutropema alter intensive chemotherapy.
Objectives: Revise all neutropenic enterocolitis diagnosed at Hospital Universitario de Canarias (HUC) in the last six and a half years in children with cancer, and carry out an up today literature review.
Patients and methods: Retrospective review of the medical histories to the children who had thyplitis. We analyzed the following data: age, sex, cancer type and chemotherapy protocol, and when thyplitis was diagnosed; days from the last cytotoxic chemotherapy cycle (anticancer drugs used), days of neutropenia, symptoms, diagnosis method used (maximum thickness on the bowel wall), treatment and evolution.
Results: Forty one cases of malignant neoplasms were treated with chemotherapy and 7,3% (n = 3) had one or more episodes of neutropenic enterocolitis (all of them with acute leukemia, two myelogenus and one lymphoblastic). All of them were male, with an average age of 11 years and 6 months. The symptom more frequently seen was abdominal pain in a child with a febrile neutropenia alter intensive chemotherapy. The diagnosis confirmation was with abdominal ultrasonography (US) in two cases, and computed tomography (CT) in the other two ones (average thickness on the bowel wall was 11,5 mm). All the children recovered without problems with medical treatment.
Conclusion: Any child with cancer treated with chemotherapy, especially with acute leukaemia, and febrile neutropenia associated with persistent abdominal pain, vomiting and/or diarrhea, we must suspect neutropenic enterocolitis, ask for an urgent abdominal US and/or CT to confirm the diagnosis, and start as far as possible the recommended treatment, achieving as that a significative morbimortality reduction so common in this severe complication.
