Description
Objective To identify CT findings predictive of surgical management in non-emergency small bowel obstruction (SBO). Methods Contrast-enhanced abdominal CT of 129 patients with non-emergency SBO were evaluated for small bowel luminal diameter, wall thickness, presence of the small bowel faeces sign (intraluminal particulate matter in a dilated small bowel) and length, transition point, submucosal oedema, mesenteric stranding, ascites and degree of obstruction (low grade partial, high grade partial and complete obstruction). Medical records were reviewed for age, gender, management and history of abdominal surgery, abdominal malignancy, or SBO. Statistical analyses were performed with Stata Release 9.2. Results Degree of obstruction was the only predictor of need for surgery. Whereas 18.0% of patients with lowgrade partial obstruction (n=50) underwent surgery, 32.5% of patients with high-grade partial obstruction (n=77) and 100% of patients with complete obstruction (n=2) required surgery (P=0.004). The small bowel faeces sign was inversely predictive of surgery (P=0.018). Conclusion In non-emergency SBO patients with contrastenhanced CT imaging, grade of obstruction predicts surgery, while the small bowel faeces sign inversely predicts need for surgery.
