[Ileitis following capecitabine use].

BACKGROUND: Over a period of 1 year in our hospital, 3 patients were diagnosed with 'ileitis following capecitabine use'. The case of 1 of these patients is presented in this article. CASE DESCRIPTION: A 73-year-old man known to be suffering from liver metastases from rectal cancer was treated with oxaliplatin, bevacizumab and capecitabine. He was admitted to our hospital with abdominal pain, diarrhoea, nausea and a subfebrile temperature. A CT scan of the abdomen showed marked bowel wall thickening, particularly of the ileum, consistent with terminal ileitis. The diagnosis was 'ileitis following capecitabine use' since other disorders were excluded or seemed less likely, and the Naranjo score was compatible with 'possible adverse reaction'. Capecitabine treatment was discontinued. Following recovery, treatment was resumed without complications.
CONCLUSION: Small intestine toxicity during capecitabine use has, to our knowledge, not been described previously. It is important to recognise this side-effect in order to avoid obstruction and perforation. Conservative treatment including an adapted diet and intravenous hydration is the therapy of choice. Surgery does not seem to be indicated.
