Intestine: enteritis - idiopathic focal eosinophilic

Synonym(s): Multifocal eosinophilic enteritis, idiopathic eosinophilic enteritis, IFEE

Contributor(s): Debbie Archer, Alfred Merritt

Introduction

  • Cause: unknown.
  • Signs: small intestinal obstruction (non-strangulating).
  • Diagnosis: histology of intestinal biopsy.
  • Treatment: surgical resection.
  • Prognosis: good following resection.
  • Rare.

Pathogenesis

Etiology

  • Unknown.
  • Rule out parasites or fungi as a cause.
  • Possibly related to diet.

Pathophysiology

  • Obstruction of ingesta at site of lesion due to reduction in diameter of the bowel lumen at the site and possibly reduction in bowel wall motility at the affected site.
  • Distension of proximal small intestine.
  • Pain due to small intestinal distension progressing to gastric distension (and possible gastric rupture) if sequestered fluid is not removed by nasogastric intubation.

Timecourse

  • Unknown: may be a chronic lesion that reaches a critical mass or an acute inflammatory response.
  • Colic may have been evident for 4-12 h.

Epidemiology

  • Only 8 cases reported in literature.
