目的：探讨小儿先天性幽门狭窄Ｘ线检查方法及其Ｘ线表现的有关病理基础。方法：回顾１６例经手术证实的先天性幽门狭窄的患儿的Ｘ线检查及Ｘ线表现和手术所见。其中有６例有Ｂ超检查结果。结果：明显胃扩张１４例，胃排空延迟１６例。６例Ｂ超结果与手术所见相同。其中３例幽门管呈鸟嘴样梗阻。结论：（１）肩样征提示幽门肌肥厚明显。（２）本病必须与其它疾病鉴别。如先天性胃窦隔膜性狭窄。同时还应排除幽门暂时痉挛造成的假象。（３）Ｘ线与超声结合能为外科手术提供必要的依据。
Objective: To investigate the pediatric congenital pyloric stenosis X-ray examination method and its pathological basis of X-ray findings. Methods: X-ray examination, X-ray findings and surgical findings of 16 cases of congenital pyloric stenosis confirmed by surgery were retrospectively reviewed. Six of them had B-ultrasound results. Results: Significant gastric dilatation in 14 cases, delayed gastric emptying in 16 cases. 6 cases of B-ultrasound results and surgery see the same. 3 cases of pyloric beak-like obstruction. Conclusions: (1) Shoulder signs suggest pyloric muscle hypertrophy. (2) The disease must be identified with other diseases. Such as congenital antrum diaphragm stenosis. At the same time should also rule out the temporary illusion caused by pyloric spasm. (3) X-ray combined with ultrasound can provide the necessary basis for surgery.
