Abstract
PURPOSE: There are several diagnostic tools to support the decision for abdominal stab wounds. The aim of this study is to evaluate the ability of computed tomography (CT) to facilitate decisions on the initial management in patients with anterior abdominal stab wounds. METHODS: The medical records of all 118 patients who sustained abdominal stab wounds from March 2004 to January 2012 were reviewed retrospectively. RESULTS: The average age of patients was 41 years, and 84 (71%) patients were male. Ten patients underwent an immediate laparotomy due to hemodynamic instability, peritonitis, or definite evisceration. The other 108 patients underwent CT scans, and 91 patients had positive CT findings, leading to performance of laparotomy in 82 patients. One patient underwent a non-therapeutic laparotomy. Seventeen patients had negative CT results; however, seven patients underwent early laparotomy according to the attending surgeon's decision using serial physical examination or other diagnostic tools. The sensitivity of the CT scan was 94.2%, and the positive-predictive value was 98.8%. CONCLUSIONS: CT can be used efficiently along with physical examination as an initial diagnostic tool in patients with abdominal stab wounds. However, there can be missed injuries, then surgeon should consider other diagnostic methods.
