婴幼儿不可回复性食管裂孔疝的胸部X线征象

目的探讨婴幼儿不可回复性食管裂孔疝的胸部X线征象及其诊断价值。方法回顾性分析17例经手术和，或上消化道钡餐检查证实为不可回复性食管裂孔疝的胸部X线平片。结果17例仰卧胸部正位片显示右下胸腔肿块或厚壁囊腔16例。左下胸腔厚壁囊腔1例。肿块或囊腔外、上缘大部分光整，少数模糊；下、内缘分别与膈面、心影重叠。12例侧位片显示肿块或囊腔位于膈上心影后，其中3例立侧位囊腔内见气-液平。11例厚壁囊腔内气体影与膈下消化道内气体影相连续5例。结论胸部X线征象能够高度提示婴幼儿不可回复性食管裂孔疝的诊断。

Features of irreversible hiatus hernia on the chest X-ray film in infants

Objective To evaluate the features and diagnostic value of irreversible hiatus hernia on the chest X-ray films in infants. Methods Seventeen cases of chest X-ray films of irreversible hiatus hernia were analyzed retrospectively. Results All cases were performed supine AP chest X-ray films. Among these cases, 6 cases showed mass lesions in the right lower thorax, 10 cases and 1 case showed thickening hernia sacs in the right and left lower thorax respectively. Most border of the lesions were smooth. In all cases, the posterior border of lesions overlapped heart shadow, and the lower margin overlapped diaphragm. In 12 cases with lateral radiograph, retrocardiac hernia sac were above diaphragm, and 3 cases showed gas-fluid level in hernia sac. Contiguous gas shadow between thickening hernia sac and alimentary tract below diaphragm was showed in 5 cases. Conclusion Chest X-ray film can be used to diagnosing the irreversible hiatus hernia in infants.
