几种先天性畸形胎儿结肠的解剖及组织学观察

The Anatomical and Histological Observation of Colon in Several Congenital Malformation Fetus

目的:研究先天性畸形胎儿结肠的解剖及组织学结构,探讨几种畸形与结肠发育之间的关系。方法:应用形态学方法,对先天性畸形胎儿结肠进行解剖、观察,并制成组织切片,在光学显微镜下观察其组织学结构。结果:三类10例先天性畸形胎儿中,并缺指畸形胎儿结肠的形态学及组织学结构无明显异常;胸腹联体胎儿结肠结构异常;无脑儿结肠组织结构发育不全。结论:不同先天性畸形胎儿对结肠发育影响各异。

Purpose: To study the anatomical and histological structure of colon of congenital malformation fetus,to discuss the relationships between several malformations and the development of colon.Method: use morphological method to dissect and observe the colon of congenital malformation fetus,make-up the paraffin sections and observe the histological structures under the light-microscope.Result: in three categories and ten examples of congenital malformation fetus,the morphological and histological structures of colon in syndactyly and sxtrodactyly fetus have no obvious abnormity;the colon's structure shows abnormity in omphalo-thoracopagus twins;the colon's structure was insufficient development in anencephaly fetus.Conclusion: different congenital malformation fetuses have different effects in the development of fetus's colon.
