Diagnostic value of ultrasound in ischemic changes of intestinal volvulus in children
Objective To investigate the value of ultrasonic signs in the diagnosis of intestinal volvulus and the evaluation of intestinal ischemic changes in children.Methods The clinical and ultrasonic data of 77 cases with intestinal volvulus confirmed by operation and pathology and preoperative ultrasound examination were retrospectively analyzed.According to the presence or absence of intestinal ischemic changes during operation,they were divided into an ischemic group(with intestinal ischemic changes)and a control group(without intestinal ischemic changes),and differences of clinical features and incidence of each ultrasonic sign between the two groups were compared.Results The comparison of clinical data between the two groups showed that the age distribution of the ischemic group was significantly lower than that of the control group,with a statistically significant difference(P<0.05).Comparison of the ultrasonic signs between the two groups showed that the incidence of turbid ascites,intestinal dilation,mesenteric edema,and enhanced intestinal wall echo in the ischemic group were higher than that in the control group,with a statistically significant differences(P<0.05).The results of ROC showed that the AUC of turbid ascites,intestinal dilatation,mesenteric edema and enhanced intestinal wall echo predicting ischemic changes of intestinal torsion were 0.677,0.654,0.612 and 0.596,respectively.Conclusion In children with intestinal volvulus,the younger the age,the more ultrasound signs such as turbid ascites,intestinal dilation,mesenteric edema,and enhanced intestinal wall echo are present,which are prone to intestinal ischemia.
