Abstract

Background: Hollow viscus perforation represents one of the most common surgical abdominal emergencies. Delayed diagnosis significantly increases the risk of mortality. Therefore, early and accurate diagnosis is essential to ensure timely and appropriate treatment planning, Objectives: To describe the characteristics and evaluate the diagnostic value of multi-slice computed tomography in identifying the perforation site in patients with hollow viscus perforation in Can Tho City in 2024–2025. Results: A total of 85 patients with hollow viscus perforation were included in the study, with 52.9% male and 47.1% female. The mean age was 62.04 ± 15.89 years. Computed tomography findings revealed that 95.3% of patients had intraperitoneal free air, 52.9% had retroperitoneal air, 50.6% showed bowel wall thickening, 89.4% exhibited localized inflammatory infiltration around the site of injury, 98.8% had free intraperitoneal fluid, and 58.8% demonstrated discontinuity of the gastrointestinal wall. The diagnostic performance of multi-slice computed tomography in localizing the perforation site was high, with an area under the ROC curve of 95.3% (p < 0.001), a sensitivity of 94.4%, and a specificity of 88.1%. Conclusion: Computed tomography can aid in accurately identifying the perforation site in cases of hollow viscus perforation.
