Summary:The purpose of this study was to examine the usefulness and validity of contrast enhanced-spiral computerized tomography in assessing blunt abdominal trauma. 257 patients were admitted in a general hospital over a period of five years and were examined with computed tomography. Two-dimension reconstruction and delayed imaging were used when appropriate. 169 patients underwent a laparotomy, while 88 were treated conservatively. Scans were true positive for intraabdominal damage in 212 patients depicting chiefly splenic, liver, renal, urinary bladder, and mesenteric/intestinal injuries (41%, 18%, 6.6%, 6.6%, and 13.7% respectively). True negative examinations amounted up to 35. 10 non-specific examinations displayed the existence of hemoperitoneum but not the actual damage itself, therefore they were considered false negative. No false positive examination existed. Overall sensitivity was 95%, specificity 100%, positive predictive value 100% and negative predictive value 78%. In conclusion spiral computed tomography is a valuable examination in blunt abdominal trauma as it facilitates diagnosis of intraabdominal damage, assists in defining treatment and occasionally allows foretelling the outcome.
