PurposeThis study evaluates the accuracy of IV contrast-enhanced computed tomography (CT) tractography in the detection of peritoneal violation in anterior abdominal stab wounds (AASW) and its impact on the management algorithm.MethodsThis prospective study included 61 patients who presented to Kasr Alainy Hospital with AASW. According to the IV contrast-enhanced CT tractography, they were classified into penetrating, equivocal and non-penetrating injuries. The former two were subjected to diagnostic laparoscopy (DL), while the non-penetrating group was subjected to serial abdominal examination (SAE). The accuracy of CT tractography to detect peritoneal violation was assessed by correlating its findings with management outcome.ResultsCT tractography stratified the injuries into non penetrating (54.1%), equivocal (14.8%) and penetrating (31.1%). All non-penetrating stabs were managed successfully by SAE. DL proved negative for peritoneal violation in all equivocal injuries and positive in all injuries designated as penetrating. Consequently, sensitivity, specificity, positive and negative predictive values and accuracy of CT tractography in detecting peritoneal violation was 100%. No missed injuries were encountered in this study.ConclusionIV contrast-enhanced CT tractography is an effective tool in the evaluation of patients with AASW. Patients with negative tractography can be safely managed by SAE. Positive tractography accurately indicates peritoneal violation which warrants further management. Patients with equivocal findings were all negative for peritoneal violation by laparoscopy, therefore, they might be reallocated for frequent SAE to reduce the rate of non-therapeutic interventions.© 2020.
