Introduction This audit focused on patients who sustained enteric injury following blunt abdominal trauma. Methods Our prospectively maintained electronic registry was interrogated retrospectively, and all patients who had sustained blunt abdominal trauma between December 2011 and January 2016 were identified. Results Overall, 2,045 patients had sustained blunt abdominal trauma during the period under review. Seventy per cent were male. The median age was 28 years. Sixty patients (2.9%) sustained a small bowel injury (SBI). Thirty-five of these were peritonitic on presentation. All patients with a SBI had a chest x-ray and free air was present in seven. In 18 patients with a SBI, computed tomography (CT) was performed, which revealed isolated free fluid in 12 and free intraperitoneal air in 5. In five cases, the CT was normal. A total of 32 patients (1.5%) sustained blunt duodenal trauma (BDT). All patients with BDT had a chest x-ray on presentation. Free intraperitoneal air was not present in any. CT was performed on 17 patients with BDT. This revealed isolated free fluid or retroperitoneal air in 12. The median delay between injury and presentation for these enteric injures was 15.5 hours (interquartile range [IQR]: 8–25 hours) while between presentation at hospital and operation, the median delay was 6 hours (IQR: 3–13 hours). Conclusions Blunt trauma related enteric hollow visceral injury remains associated with delayed diagnosis and significant morbidity. It can be caused by a disparate array of mechanisms and is difficult to diagnose even with modern imaging strategies.
