About 60-70% of cases of anaphylactoid purpura suffer from abdominal colic, which may be quite severe. Because severe abdominal pain may be difficult to differentiate from a surgical abdomen, repeated examination and radiological studies are often necessary. A 4 year 7 month-old girl suffered from abdominal pain, vomiting and the skin rash characteristic of anaphylactoid purpura. Because of worsening of the abdominal manifestations, a Gastrografin enema was given. The result was normal but 48 hours later, the child suffered from acute abdominal colics plus symptoms of shock. X-ray examination revealed a large distension of colon and persistence of the contrast material. Exploratory laparotomy failed to find any perforation or necrosis. The colon was drained and the child was given parenteral nutrition and antibiotics. Blood culture showed Klebsiella pneumoniae. An upper gastrointestinal roentgenogram using meglumine ioxitalamate was performed 19 days later because of recurrence of the abdominal pain. This showed a submucosal hemorrhage in the first small bowel loop. Increased abdominal distension occurred 3 days later and the results of X-rays were similar to those seen the Gastrografin enema. A second enema using meglumine ioxitalamate was performed 3 days later. It showed sigmoid constriction but a second laparotomy failed to confirm this obstruction. The child died a few hours later despite ileostomy and antibiotics. The severe colectasy seen in this case of anaphylactoid purpura indicates that caution is required in performing enemas in acute digestive complications of this disease. Such X-ray studies should not be repeated and all water-soluble contrast material should be voided as soon as possible.
