Abstract
AIM: To investigate the diagnostic value of small bowel wall thickness and density measured by computed tomography (CT) in differentiating simple small bowel obstruction (SI) from strangulated small bowel obstruction (ST).
METHODS: Forty-two patients with SI and 38 patients with ST were included. All patients underwent plain and contrast-enhanced CT scans. The density of bowel wall thickening was recorded and compared.
RESULTS: The percentage of patients with normal inner density measured by plain CT was significantly higher in the SI group than in the ST group, and the percentage of patients with decreased whole density was significantly lower in the SI group than in the ST group (P < 0.05). The percentage of patients with decreased whole density measured by contrast-enhanced CT was significantly lower in the SI group than in the ST group (P < 0.05). The sensitivity and specificity of normal inner density measured by plain CT for diagnosis of ST were 34.2% and 33.3%, respectively. The sensitivity and specificity of decreased whole density measured by plain CT were 73.7% and 71.4%, respectively. The sensitivity and specificity of decreased whole density measured by contrast-enhanced CT were 84.2% and 73.8%, respectively.
CONCLUSION: Small bowel wall thickness and density changes measured by computed tomography can help differentiate between SI and ST.
