BACKGROUND/OBJECTIVE: Despite extensive published research, the surgical approach to penetrating abdominal trauma patients is still under debate. Computed tomography-guided tractography (CTT) is an imaging modality in which water soluble iodinated contrast medium is administered into the site of the injury in the CT unit. The aim of this study was to determine the diagnostic accuracy of the CTT.
METHODS: A retrospective evaluation was made of patients admitted to the Emergency Department with penetrating abdominal trauma and who underwent CTT. Contrast enhanced abdominal CT and CTT reports, surgical findings and clinical results were examined.
RESULTS: Evaluation was made of a total of 101 patients comprising 89 males (88.1%) and 12 females (11.9%). CTT was determined to have 92.8% sensitivity, 93.6% specificity, 97% positive predictive value, and 85.5% negative predictive value. In 27 patients (26.7%) where the CTT indicated passage through the peritoneum, no parenchymal organ injury was present. Only one patient (2.9%) without peritoneal penetration on CTT had organ injury at exploration. No procedure-related morbidities developed.
CONCLUSION: CTT is a safe imaging modality for the evaluation of hemodynamically stable patients. Compared to other imaging modalities, there is clearer demonstration of whether or not the peritoneum is intact. However penetration on CTT does not exactly correlate with organ injury.
