ULTRASONOGRAPHY TO DIAGNOSE AND EXCLUDE INTUSSUSCEPTION IN HENOCH-SCHONLEIN PURPURA

Abdominal pain is a frequent symptom in the child with Henoch-Schonlein purpura and raises the suspicion of intussusception or perforation. One hundred and fifty two children with a diagnosis of Henoch-Schonlein purpura over 11 years were reviewed. Of these 60 had abdominal pain, 19 gastrointestinal bleeding, and nine were suspected intussusception. Intussusception was confirmed in two of these cases with ultrasonography. Ultrasound is an important tool in the early diagnosis of intussusception complicating Henoch-Schonlein purpura. Where the intussusception appears loose an expectant policy, with careful monitoring, may allow spontaneous reduction. It may also be used in monitoring patients for postoperative recurrence of intussusception, mural haematoma, and uncomplicated intestinal vasculitis with oedema.
