The charts of 103 children with a clinically and surgically confirmed diagnosis of congenital hypertrophic pyloric stenosis were retrospectively reviewed. We found a significant correlation between sonographic and surgical measurements of the muscular thickness of the pylorus (r = .987, P < .001). In 73.7% (76 cases), the clinical picture of gastric outlet obstruction was present when the thickness of the enlarged pyloric muscle was 3.0 mm or more. In 26.3% (27 cases), the pyloric muscle was less than 3.0 mm wide. For 10 patients in whom the muscle width was less than 2.5 mm by sonography, a barium meal was necessary to confirm the diagnosis. The width of the pyloric muscle is the most important factor in the sonographic diagnosis of pyloric stenosis, and even a width of less than 3.0 mm may be associated with clinically significant obstruction.
对103例经临床和手术确诊为先天性肥厚性幽门狭窄的儿童病历进行了回顾性研究。我们发现幽门肌层厚度的超声测量值与手术测量值之间存在显著相关性（r = 0.987，P < 0.001）。当增大的幽门肌厚度为3.0 mm或更厚时，73.7%（76例）出现胃出口梗阻的临床表现。26.3%（27例）的幽门肌宽度小于3.0 mm。对于超声检查显示肌层宽度小于2.5 mm的10例患者，需要进行钡餐检查以确诊。幽门肌宽度是幽门狭窄超声诊断中最重要的因素，即使宽度小于3.0 mm也可能伴有具有临床意义的梗阻。
