Objective To explore the instruction value of the color Doppler ultrasonography for the diagnosis and treatment of the pediatric intussusceptions .Methods Retrospective study the color Doppler ultrasonographic performance of 114 patients with diagnosis of pediatric intussusception in the affiliated hospital of Zunyi medical college ,from October 2009 to June 2012 ,reviewed the case ,groups were compared according to the ways of therapeutic methods .Results All the 114 cases of children of the intus-susception are subject to air enema reset or surgery cured confirmed .Age younger than 12 months intussusception children ,air ene-ma reset were more likely to success ;the diameter of concentric circles levy,the length of sleeve for and the thickness of bowel wall were smaller ,the more suitable for outsiders air enema reset .The blood supply of scabbard of bowel wall and the mesenteric was rich ,the air enema reset had a higher success rate ,blood supply was poor and the success rate was lower .The success rate of air enema reset was influenced by the part of intussusception .Conclusion Combined use of conventional color ultrasonic and high fre-quency probe checking ,can raise the diagnosis rate of pediatric intussusception ,the primary lesion confirmed and the detection rate in the position of the disease ,provide guidance for clinical choice reduction treatment .
