Investigation of childhood blunt abdominal trauma: a practical approach using ultrasound as the initial diagnostic modality

Abstract

During a 5.5-year retrospective study (1979-84) 170 children with blunt abdominal trauma were investigated with intravenous urography (IVU), ultrasound (US) and scintigraphy. For the investigation of the last 71 children (after 1982) a 4th generation CT scanner was available in the same department. The results of radiologic investigations were compared with clinical outcome in 157 and results at laparotomy in 13 children. During the study period, real time US became the first line screening tool, and was combined with IVU in suspected renal trauma. In spite of permanent accessibility of CT since November 1982, the latter was used only in complex diagnostic problems or in children with multiple injuries (8% of the series). There were no deaths resulting from abdominal trauma. During the study, the incidence of splenectomy and exploratory laparotomy decreased, and no diagnostic peritoneal lavage were performed after 1980.
