小儿肠套叠空气灌肠后盲肠存留小于2.0cm肿物影现象的解读

Explanation of the phenomenon that there is a lump less than 2.0 cm in the caecum after enforcing air enema for infant intussusceptions

目的解读"肠套叠经空气灌肠后,盲肠最终存留直径<2.0cm的肿物,且见极少量气体进入小肠"的现象,并探讨其实际价值。方法将54例经空气灌肠后未达复位标准的肠套叠患儿分为两组,即"经空气灌肠后,盲肠最终存留直径<2.0cm的肿物且见极少量气体进入小肠组"(A组)18例与"经空气灌肠后盲肠最终存留直径>3.0cm的肿物,且未见气体进入小肠组"(B组)36例,比较二者的肠套叠解除情况。结果 A组肠套叠空气灌肠后解除率为88.9%,显著高于B组肠套叠的零解除率(P<0.05)。结论 "肠套叠经空气灌肠后,盲肠最终存留直径<2.0cm的肿物,且见极少量气体进入小肠"的现象提示,绝大多数肠套叠已解除,但仍有少部分患者存在短段肠套叠。

Objective To explain the phenomenon that there is a lump less than 2.0 cm in the caecum and a little gas came into small intestine after enforcing air enema for infant intussusception. Methods The 54 cases which could not reach replacement criterion after enforcing air enema for infant intussusception were divided into two groups as follows： the group conraining 18 cases with a lump less than 2. 0 cm in the caecum and a little gas coming into small intestine after enforcing air enema for intussusception （group A） ; the group containing 36 eaces with a lump more than 3.0 em in the caecum and no gas coming into small intestine after enforcing air enema for intussusception （group B）. Their intussuseeptions rate comfirmed eventuall were compared. Results The former＇s intussusception replacement rate of group A was 88.9%. The former＇s intussusceptions replacement rate of group B was 0%. The replacement rate of group A was obviously higher than group B （P〈0.05）. Conclusion The phenomenon that there is a lump less than 2.0 cm in the caecum and a little gas comes into small intestine after enforcing air enema for intussusception in children indacates that most of intussusception has been replaced, but there is a few caces remaining short intussusception.
