title: Acute abdominal pain in children.
abstract: Acute abdominal pain in children presents a diagnostic dilemma. Although many cases of acute abdominal pain are benign, some require rapid diagnosis and treatment to minimize morbidity. Numerous disorders can cause abdominal pain. The most common medical cause is gastroenteritis, and the most common surgical cause is appendicitis. In most instances, abdominal pain can be diagnosed through the history and physical examination. Age is a key factor in evaluating the cause; the incidence and symptoms of different conditions vary greatly over the pediatric age spectrum. In the acute surgical abdomen, pain generally precedes vomiting, while the reverse is true in medical conditions. Diarrhea often is associated with gastroenteritis or food poisoning. Appendicitis should be suspected in any child with pain in the right lower quadrant. Signs that suggest an acute surgical abdomen include involuntary guarding or rigidity, marked abdominal distention, marked abdominal tenderness, and rebound abdominal tenderness. If the diagnosis is not clear after the initial evaluation, repeated physical examination by the same physician often is useful. Selected imaging studies also might be helpful. Surgical consultation is necessary if a surgical cause is suspected or the cause is not obvious after a thorough evaluation.
