摘　　要：本文应用Ｂ超对６６例临床可疑肥厚性幽门狭窄（ＨＰＳ）患儿进行检查，Ｂ超诊断ＨＰＳ４６例、幽门狭窄１例、超声无异常１９例。４６例ＨＰＳ除１例因重度营养不良伴重度肺炎于Ｂ超检查后即死亡外，余４５例均由手术证实。１例Ｂ超诊断为幽门痉挛的患儿，１０天后经手术证实为ＨＰＳ，考虑漏诊的原因可能与Ｂ超检查时，其幽门肌层未达到一定厚度有关。Ｂ超无异常的１９例除１例因肠旋转不良予手术治疗外，其余经保守治疗后症状均获缓解及消失。Ｂ超诊断的准确性达９８．５％，敏感性和特异性分别为９８％和１００％。本研究证实Ｂ超诊断ＨＰＳ准确性高，且安全方便易行，婴儿可避免钡餐和Ｘ线照射，并减少吸入性肺炎的危险，建议Ｂ超可作为诊断ＨＰＳ的首选手段，对Ｂ超检查在一周内连续二次阴性的可疑者，可再予ＧＩ检查以排除其他胃肠道疾患。Sixty-six suspected hypertrophic pyloric stenosis (HPS) children were examined by ultra sound (US), forty-six HPS cases, one pyloric spasm case and 19 normal cases were diagnosed by US. All HPS cases, but one died from severe pneumonia and malnutrition before surgery, were confirmed by operation. One case was misdiagnosed. The symptoms of the rest 19 cases with normal sonography were alleviated and disap peared eventually. The accuracy, sensitivity and specificity of sonographic diagnosis on HPS were 98.5%, 98% and 100%, respectively.
