小儿急性阑尾炎流行病学

来源:[标签:来源] | 发布时间:2011-07-31 10:25:02 | www.chinesejk.com
流行病学: 阑尾炎可发生在小儿的任何年龄较大儿童的发生率高随着年龄的增长而逐渐增多,6~12岁达到高峰。5岁以下的发生率相对减少,3岁以下特别是1岁以内的阑尾炎很少见。有人曾做过统计,发生在3岁以内的阑尾炎占阑尾炎病例的5%~9.6%而5岁以内占12%~20%。虽然发病率少,但由于症状不典型加之病情变化快,往往误诊率很高因治疗不及时而造成阑尾穿孔者可达20%~40%国外报道为14%并且年龄越小,穿孔率越高因此阑尾炎的早期诊断和正确治疗非常重要。男孩与女孩的发生率大致相等但有人报告男孩的发生率稍高男女之比为1∶1~3.5∶1
