High-frequency color Doppler in infant intussusception diagnosis and treatment / 中国基层医药

ABSTRACT

Objective To explore the application of high-frequency color Doppler in the diagnosis of infant intussusception and the selection of reduction mode according tO the hemodynamic situations of intussusception intestine tube and blood vessel in mesentery.Methods A total of 377 cases of doubtful intussusception infants wete checked by high-frequency color Doppler.After they had been diagnosed,the hemodynamic situations of intussuscepiton intestine tube and blood vessel in mesentery were carefully observed and the ultra-sound had 3 types and then the hydrostatic enema reduction was chosen as treatment method.Results A total of 263 cases was diagnosed by highfrequency colot Doppler with rate of coincidence of 100%.Among them are 253 successful cases reduced by hydrostatic enema.The successful rate of reduction was 96.2%and the 10 failed cases were changed to be treated bv operation.The intestinal wall of intussusception tube in failure group had serious dropsy without blood flow shown.Conclusions It is accurate that the infant intussusception is diagnosed by high-frequency color Doppler.According to the hemodynamic situations of intussusceptin intestine tube and blood vessel in mesentery,the infant intussusception can be divided into 3 types as followstype Ⅰthe blood signal of intestinal tube and wall is up or normal,which shall be reduced by hydrostatic enema;type Ⅱthe blood signal of intestinal tube and wall is small with high obstruction index,which shall be reduced by hydrostatic enema as possible as it can;type Ⅲthe intestinal wall has serious dropsy with rather high obstruction index and without blood flow shown,in which the hydrostatic enema redHetion shall bebanned and the operation shall be carried out as soon as possible.
