摘要 目的:通过X线腹部平片对肠道气体进行定量分析,探讨肠易激综合征(IBS)患者肠道气体量的变化。方法:根据罗马Ⅲ诊断标准选取IBS患者49例(便秘型25例和腹泻型24例),健康对照者25例,在空腹状态下摄立位腹部平片,扫描进入计算机,用图像处理软件(Photoshop 7.0)处理照片,在双肋弓外缘垂直线相交于膈顶水平线、耻骨联合上缘水平线形成的矩形框内,标出肠道内气体范围,分别计算整个矩形框及肠气范围的像素值,最后结果用气体容积积分表达(gas volume score,GVS),即肠气范围像素值与矩形框像素值之比。结果:IBS患者的GVS与健康对照组比较无明显差异(0.064±0.035vs0.055±0.043);便秘型IBS患者的GVS明显大于腹泻型IBS患者(0.077±0.040vs0.051±0.025,P<0.01)及健康对照组(0.077±0.040vs0.055±0.043,P<0.05),而腹泻型IBS患者的GVS与对照组相比无差异(0.051±0.025vs0.055±0.043,P>0.05)。结论:IBS患者肠道气体的量存在变化,且与IBS分型有关,便秘型IBS患者肠道气体增多,腹泻型IBS患者肠道气体无改变。
