Abstract
BACKGROUND: The incidence of blunt bowel and mesenteric injury (BBMI) has increased recently in blunt abdominal trauma, possibly due to an increasing number of high-speed motor accidents and the use of seat belts. OBJECTIVE: Our aim was to identify the factors determining the time of surgical intervention and how they affect the outcome of the patient with BBMI. This was achieved by reviewing our experience as a major Victorian trauma service in the management of bowel and mesenteric injuries and comparing this to the experiences reported in the literature. METHODS: A retrospective study reviewing 278 consecutive patients who presented to the Alfred trauma center with blunt bowel and mesenteric injuries over a 6-year period. RESULTS: The patient cohort comprised 278 patients with BBMI (66% were male, 34% were female), of whom 80% underwent a laparotomy, 17% were treated conservatively and 3% were diagnosed post-mortem. In terms of time from admission to laparotomy, 67% were treated within 0-4 h, 9% within 4-8 h, 3% within 8-12 h, 10% within 12-24 h, 4% within 24-48 h and 7% at >48 h. A focused abdominal sonography for trauma (FAST) was performed in 86 patients, of whom 51% had a positive FAST, 44% had a negative FAST and 4% had an equivocal FAST. Overall, 13% of the patient cohort did not have a FAST. Computerized tomography (CT) scans were undertaken preoperatively in 68% of the patients, revealing free gas (22% of patients), bowel-wall thickening (31%), fat and mesenteric stranding or hematoma (38%) and free fluid with no solid organ injury (43%). CONCLUSION: The timing of surgical intervention in cases of BBMI is mostly determined by the clinical examination and the results of the helical CT scan findings. The FAST lacks sensitivity and specificity for identifying bowel and mesenteric trauma. A delayed diagnosis of > 48 h has a significantly higher bowelrelated morbidity but not mortality.
