目的探讨小儿急性阑尾炎的超声诊断价值及误诊原因分析。方法对2008-01-2010-12在曲靖市第一人民医院门诊急诊经超声检查并经住院手术证实的87例急性阑尾炎患儿进行回顾性分析。结果 87例患儿,超声诊断急性阑尾炎63例,包括急性阑尾炎、阑尾周围脓肿及右下腹异常回声,考虑急性阑尾炎三种情况,诊断符合率72.4%,漏诊24例,占28.5%,其中4例表现为肠腔扩张;5例表现为右下腹肠蠕动活动频繁;7例表现为右下腹或盆腔积液;8例表现为腹部肠腔胀气过多而显示不清。结论小儿急性阑尾炎超声表现可分为三种类型:典型急性阑尾炎声像表现;非典型急性阑尾声像表现;腹部肠腔胀气过多声像表现,由于小儿特殊的生理功能及各种主客观原因易漏诊。
