Case 25-2012: A 15-year-old boy with abdominal pain, hematochezia, and anemia

摘要

A 15-year-old boy was admitted to this hospital because of recurrent abdominal pain and diarrhea. The patient had been well until approximately 8 months earlier, when episodes of midline low back pain developed, which were worse in the morning and improved with activity and flexion. During the next few months, intermittent, stabbing periumbilical and left upper abdominal pain occurred, associated with nausea and diarrhea. The pain occurred once or twice a week, developed suddenly, and lasted from a few hours to a week, but typically 1 to 2 days. The pain had no relationship to eating, was unaffected by position or the passing of stool, and was not associated with nausea or vomiting. Acetaminophen provided slight relief.
