Abstract
A 13-year-old boy visited a hospital because of vomiting and abdominal pain, but no symptomatic remission could be gained. Thereafter the patient had stools with massive fresh blood. He was seen at the department of pediatrics in our hospital and had been conservatively treated with the diagnosis of hemorrhagic enteritis. However, his tenderness came to extend to the entire abdomen and he was referred to our surgical department. On the same day we diagnosed the case as acute abdomen and performed laparoscopy that revealed a hemorrhagic lesion in the upper portion of the jejunum. We made a small laparotomy and performed partial resection of the small intestine. The resected specimen included multiple ulcers. The histopathological diagnosis was small bowel ulcer secondary to allergic purpura.
It is believed that the disease generally carries good prognosis, but sometimes it can cause massive hemorrhage when it is complicated by small bowel ulcer. Early diagnosis of the hemorrhagic site and early treatment are thus mandatory.
