多次空气灌肠在小儿肠套叠整复中的价值

目的：探讨多次空气灌肠在小儿肠套叠整复中的临床价值。方法对90例在X线下行空气灌肠复位的肠套叠患儿病例进行回顾性分析。根据复位时空气灌肠次数的不同分为单次灌肠组和多次灌肠组，计算两组复位的成功率并进行统计学比较，以P＜0.05为差异有统计学意义。结果空气灌肠整复肠套叠的总成功率为86.67%。单次灌肠组、多次灌肠组例数分别为36例和54例，复位成功病例分别为26例、52例，复位成功率分别为72.22%、96.30%；单次灌肠组、多次灌肠组的成功率差异有统计学意义（ P＜0.05）。结论同等压力下和灌肠持续时间下，适当增加空气灌肠次数对提高小儿肠套叠复位的成功率有重要的作用。

The value of multiple airenema in child intussusception restitution

Objective To explore the clinical value of repeated air enema on the reduction of intussusception in children. Methods 90 cases of intussusception which reduction by air enema under X-ray examination were analyzed retrospectively. According to the different number of reduction by air enema the cases divided into single enema group and multiple enema group, the successful rate of reduction of two groups were calculated and analyzed, using P 〈 0.05 as the difference has statistical significance. Results The total successful rate of air enema reduction of intussusception was 86.67%. The case number of single enema group, repeated enema group were 36 and 54, the success cases of reduction were 26, 52.The success rate of reduction were 72.22%, 96.30%; the difference bettween the success rate of single enema group and repeated enema group was statistics significance（P 〈 0.05）. Conclusion Appropriately increasing air enema number under the same pressure and enema duration,it is important to improve the successful rate of reduction of intussusception in children.
