Hypertrophic pyloric stenosis (HPS) is the most common cause of gastric outlet obstruction in infants, with an incidence of 1.5 to 3 per 1000 live births, and classically presents at 3 to 4 weeks of age. Delayed presentation of HPS is an extremely rare occurrence after early infancy. With the exclusion of congenital HPS, gastric outlet obstruction in childhood is a rare condition (1:100,000). We report a case of delayed presentation of HPS in a 4 1/2-year-old child in whom the pylorus was hypertrophied and appeared like an "olive," and for which pyloromyotomy was curative.
肥厚性幽门狭窄（HPS）是婴儿胃出口梗阻最常见的原因，发病率为每 1000 例活产儿中 1.5 至 3 例，经典表现为出生后 3 至 4 周。HPS 的延迟表现是婴儿早期后极罕见的情况。除先天性 HPS 外，儿童胃出口梗阻是一种罕见的情况（1:100000）。我们报告了一例 4 岁半儿童的 HPS 延迟表现，其幽门肥厚，呈“橄榄”状，行幽门肌切开术即可治愈。
