Peritoneal lavage in pediatric patients sustaining blunt abdominal trauma: a reappraisal

One hundred twenty-eight patients from 0 to 18 years of age underwent diagnostic peritoneal lavage following blunt abdominal trauma. Seventy-eight had negative lavages and 50 were positive. Forty-one patients underwent exploratory celiotomy after positive lavage results. A review of the operative findings and need for surgical intervention led to the conclusion that 12 of these operations were not necessary. Due to the oversensitivity of peritoneal lavage a strongly positive result mandates further diagnostic evaluation unless the patient's clinical status requires exploratory celiotomy.
