【摘要】 目的通过对小儿肠套叠患者行透视下空气灌肠检查及复位治疗,并与超声检查结果相对比,评价超声检查在小儿肠套叠诊断中的应用价值。方法收集我院2006年7月—2008年1月经超声诊断并在透视下空气灌肠复位治疗成功的113例患者资料,按发病时间分为<12h、12~24h、>24h三组,分别记录各组平均套入部长度及空气灌肠复位平均压力,进行对照研究。结果在诊断肠套叠部位上超声与透视下空气灌肠所见按回盲部、升结肠至肝曲、肝曲远端分组,诊断符合率分别为89.6%、98.0%及78.9%,发病时间越长,套入部长度越长,空气灌肠平均复位压力越大。结论应用超声对肠套叠可做到早期诊断,不仅能得出部位、血运等多方面的结论,还可通过超声测量套入部长度,对空气灌肠的风险做出评价,并对整复压力的估计有重要指导作用。更多还原

【Abstract】 Objective Compared with air enema,to explore merit of ultrasound diagnosis of intussusception and the significance of guidance to air enema.Methods Total 113 children diagnosed by ultrasound and air enema reduction successfully were retrospectively analyzed.The patients were grouped by history of intussusception(<12 h,12-24 h,>24 h).The mean depth of lead points and pressure of air enema were calculated,and relationships between them were analyzed.Results In aspect of level diagnosis,the coincidence between ultrasound and air enema was 89.6%(ileocecal junction),98.0%(ascending colon and hepatic flexure)and 87.9%(transverse colon)respectively.The lead point’s depth of intussusception measured by ultrasound and pressure of air enema were positive correlation.Conclusion Ultrasound could diagnosed intussusception early and provided information of location and circulation.Furthermore,by ultrasound measuring lead point’s depth of intussusception,the risk of air enema could be evaluated and to estimate the pressure of air enema.更多还原
