Value of CT findings in predicting the need for surgery in patients with small bowel obstruction / 实用放射学杂志

ABSTRACT

Objective To investigate the value of CT findings in predicting the need for surgery in patients with small bowel obstruction (SBO).Methods Seventy patients with SBO were classified into non-operation and surgery groups according to the clinical treatment.The CT findings were retrospectively compared between the two groups,and the predictive value for surgery of useful CT findings was analyzed.Results Thirty three of 70 patients were cured with non-operative treatment and other 37 with surgery.The incidences of complete collapse of transitional zone,mesenteric edema,ascites,engorgement of mesenteric veins,decreased enhancement of bowel wall,decreased enhancement of mesenteric arteries and veins in surgery group were statistically higher than those in non-operation group,with odds ratios for surgery of 10.56,5.13,4.72,5.45,5.77,3.02 and 6.59,respectively.The diameter of dilated bowel,bowel wall thickness,and the incidence of target sign,intestinal pneumatosis,displacement,convergence and tortuosity of mesenteric vasculatures were not statistically different between the two groups.Conclusion Multiple CT findings of SBO are useful to predict the need for surgery,and may provide important information for clinical management of SBO.
