摘要

目的探讨超声检查在先天性幽门前瓣膜诊断中的价值。方法分析幽门前瓣膜声像图特点，总结幽门前瓣膜声像图特征。结果 12 例先天性幽门前瓣膜患儿中，超声能实时直观显示位于幽门窦部瓣膜样结构 5 例，其中合并幽门肌层肥厚性狭窄2例。余7例幽门部未发现异常瓣膜样结构及幽门肌层肥厚征象，但能观察到幽门梗阻征象：胃潴留、胃内容物通过幽门极缓慢或困难，动态观察4例可见胃-食管反流征象等超声表现。术后证实均为幽门前瓣膜，超声能直观显示瓣膜结构的5例，其瓣膜位于幽门窦部；不能直观显示瓣膜结构的7例，其瓣膜位于幽门管腔内，故超声能确切显示窦部的瓣膜，虽不能显示幽门管腔内的瓣膜，但能提示幽门梗阻存在。结论超声诊断先天性幽门前瓣膜具有较高临床实用价值，可为临床术前术式选择提供可靠影像信息。

Abstract

Objective To evaluate the value of ultrasonic diagnosis of congenital prepyloric diaphragm. Methods Twelve cases were collected for the analysis of the characteristics of ultrasonography in diagnosis of congenital prepyloric diaphragm. Results Of the 12 cases of congenital prepyloric diaphragm

valvula in pyloric antrum could be observed in 5 cases

inclusive of 2 cases of complicating pachyntic stenosis of pyloric muscular layer. Other valvula in pyloric canal could not be found with ultrasonography. No pyloric muscular layer pachynsis was observed

but signs of pyloric obstruction such as gastric retention

slow or difficult transfer of gastric contents

gastro-esophageal reflux were found. Prepyloric diaphragm was confirmed surgically in all cases. Conclusion Ultrasonic diagnosis of congenital prepyloric diaphragm is of practical value in clinical practice and can provide reliable imaging data for the option of preoperative approaches.
