Abstract:
Objectives:To study the computed tomography features of banded adhesions(BA) and matted adhesions(MA) of adhesive small bowel obstruction(ASBO).Methods:We enrolled 150 patients operated on for ASBO. According to intraoperated findings, ASBO were classified into those caused by BA or MA. A multivariable logistic regression was established to analyze independent risk factors on Computed Tomography features.Results:There were significant differences in closed-loop sign (36.8% vs. 14.3%, P=0.002) mesenteric haziness (43.7% vs. 17.5%, P=0.001), beak sign (48.3% vs. 17.5%, P<0.001), fat notch sign (39.1% vs. 9.5%, P<0.001) and peritoneal fluid (54.0% vs. 34.9%, P=0.015) between the two groups. The presence of beak sign [ OR=6.15, 95% CI (2.55-14.84), P<0.001], fat notch sign [ OR=6.19, 95% CI (2.16-17.82), P=0.001] and mesenteric haziness [ OR=3.34, 95% CI (1.34-8.32), P=0.009] were independent risk factors with BA. Conclusion:Beak sign, fat notch sign and mesenteric haziness were independent risk factors for diagnosing BA.
