The authors analysed 45 ultrasonography (US) studies of 43 infants with surgically confirmed hypertrophic pyloric stenosis (HPS) to ascertain whether the current US criteria for pyloric stenosis are applicable to all infants, including those 30 days of age and younger. Most articles in the radiologic literature cite a muscle thickness of 4 mm or greater and a pyloric canal length of 17 mm or greater as diagnostic of HPS. However, the results of this study suggest that in infants 30 days of age or younger the muscle thickness considered diagnostic for HPS be 3 mm or greater.
作者分析了43例经手术确诊为肥厚性幽门狭窄（HPS）的婴儿的45份超声检查（US）研究，以确定当前用于诊断幽门狭窄的超声标准是否适用于所有婴儿，包括30日龄及以下的婴儿。放射学文献中的大多数文章将肌肉厚度4mm或更大以及幽门管长度17mm或更大作为诊断HPS的标准。然而，本研究结果表明，对于30日龄及以下的婴儿，诊断HPS的肌肉厚度应为3mm或更大。
