摘要
选用无消化道畸形的胎儿、新生儿、婴儿尸体40例.固定后测量食管长度、生理性狭窄及扩张部横径、腹段食管、膈食管裂孔及胃食管角,在光镜下测量食管下端约肌长度.研究提示:无论在胎儿、新生儿及婴儿均已存在上述结构,并有随年龄增长而增长趋势.
Forty fetus, neonate and infant cadvers without gastro-enterologic malformations were examined. The length of esophagus, the diameter of the esophageal physical stenosis and dilated parts,the intra-abdominal segment of esopagus, phrenoesophageal hiatus and gastroesophageal angle weremeasured. The length of lower esophageal sphincter was also determined. The results indicated thatthe structures mentioned above were found in all fetuses neonates and infants and tended to develop were with age.
