Background & Aims: The injuries of hollow organs are less known than the injuries of solid organs and delay in their diagnosis can increase mortality and complications in patients. The diagnostic value of CT scan in hollow organ damage has been less investigated. Therefore, the present study was conducted with the aim of determining the diagnostic value of abdominal and pelvic CT scan with intravenous contrast in the diagnosis of hollow viscera damage in blunt trauma patients.
Materials and Methods: In this cross-sectional study, 90 blunt trauma patients were included in the study. Clinical data of patients with blunt abdominal trauma who underwent CT scan and laparotomy were collected. The diagnostic value of CT scan compared to the results of laparotomy as a gold standard was analyzed by calculating sensitivity, specificity, positive and negative predictive value and accuracy.
Results: 69 patients (76.7%) were male and 21 patients (23.3%) were female. The mean age of the patients was 29.82 ± 17.51 years. Based on laparotomy, there was no injury in 60% of patients (54 patients) and in 36 patients (40%) damage to hollow organs was diagnosed. In general, the sensitivity, specificity, positive predictive value, negative predictive value and accuracy of CT scan were 22.2%, 100%, 100%, 65.8% and 68.9%, respectively. The sensitivity of CT scan was 12% for bowel damage and 62.5% for bladder damage. The sensitivity of CT scan for intra-abdominal/pelvic fluid (31.25%) was the highest and the specificity and positive predictive value for other CT scan findings were similar (100%).
Conclusion: While the sensitivity of CT scan in detecting hollow viscera injuries is low, its specificity, positive predictive value, negative predictive value, and accuracy are high and acceptable. Therefore, CT scan can be used as a complementary tool along with other diagnostic methods to diagnose hollow organ injuries in blunt trauma patients.
