摘要
目的总结儿童肠套叠空气灌肠复位的经验．方法回顾分析１４１例（１４５次）儿童肠套叠空气灌肠整复率和其中２５例灌肠复位失败的情况．所有病例对整复率与病程、套叠部位、全身情况（肠梗阻、脱水）的关系进行了统计分析．结果本组１４１例空气灌肠整复率为８２７％，统计学分析表明．整复成功与否与病程长短（＜２４ｈ为９２７％，４８ｈ～９６ｈ为５０１％），套叠部位远近（肝曲近侧为９２５％，降结肠到乙状结肠为５３３％），患儿全身情况（有无肠梗阻、脱水程度）有紧密关系．影响空气灌肠整复成功与否有多种因素，两种以上因素组合较单一因素更能预示灌肠复位的难易，认真选择适应证，提高整复技巧，将能提高整复率．结论儿童肠套叠空气灌肠１４１例１４５次，整复率８２７％．
AIM To summarize the experience of air enema reduction in childhood intussusception. METHODS Air reduction in 141 cases of childhood intussusception (145 attempts) was retrospectively reviewed, and surgical findings and clinical features were analysed in 25 cases of failed reduction. Statistical analysis was made between reduction rate and disease duration, the location of apex of intussusception and systemic symptoms (bowel obstruction, dehydration). RESULTS The reduction rate was 82 7% in our group. Statistical analysis showed significant association between successful air reduction and disease duration (in 24h, 92 7%; 48h～96h, 50 1%), location of apex of intussusception, systemic symptoms (absence of bowel obstruction, severity of dehydration). Many clinical features affected the success possibility of gas enema reduction. A combination of these factors was more likely than a single factor to predict the outcome of air reduction. Selecting indication carefully and improving the technique of reduction may increase the reduction rate. CONCLUSION The success rate of air enema reduction in childhood intussusception is 82 7%.
