peritoneal lavage or surgery to assess the diagnostic value of ultrasonography. The Epi Info statistical software version 3.4.1 was used for data analysis. By scanning to detect free fluid, sensitivity, specificity, positive and negative predictive values and the diagnostic accuracy were 96%, 67%, 94%, 75%, and 91% respectively. By scanning to detect the parenchymal injury, sensitivity, specificity, positive and negative predictive values and diagnostic accuracy were 71%, 35%, 62%, 44%, and 56% respectively. In conclusion, ultrasonography has a high diagnostic value in the screening of patients with blunt abdominal trauma. Scanning for the presence of free fluid yields better results than scanning for the visceral parenchymal injury.

Diagnostic value of abdominal ultrasonography in patients with blunt abdominal trauma Sir, Despite the trend to comprehensively investigate the patients with blunt abdominal trauma with a computerized tomography scan, diagnostic ultrasonography remains an important tool more so where computed tomography is not available or condition of the patient precludes transfer to the radiology suite.[1-3] This study assessed the diagnostic value of ultrasonography in blunt abdominal injury. It was a prospective study conducted at the Department of Surgery, Jos University Teaching Hospital from 1 January 2006 to 31 December 2007. Fifty-seven patients who had ultrasonography for blunt abdominal trauma had their sonographic findings compared with findings at diagnostic 308
