小儿盲肠和阑尾的年龄解剖学研究

AN AGE-SPECIFIC ANATOMICAL STUDY OF CHILDREN CAECUM AND APPENDIX

分六个年龄组观测了１８０具小儿尸（男９９，女８１）盲肠和阑尾的位置、形态和长度。随着年龄的增长，盲肠的位置由右髂嵴上方下降到右髂窝，盲肠的外形由漏斗型逐渐过渡为右袋特大型。阑尾的位置多变，无明显规律性及年龄特征。Ⅰ～Ⅲ组小儿盲肠和阑尾的长度增长较快。阑尾根部的体表投影随盲肠下降而逐渐向下方移位。

children cadavers(male 99, female 81) were divided into 6 groups according to their age. The positions, shapes, and lengths of the caecum and appendix were observed in all groups. The position of the caecum moves down from the upper of the right iliac crest to the right iliac fossa and the shape of caecum varies gradually from funnel type to right bigest bag type, as the age increases. The position of appendix is variable and there is no regularity accompaning with age. The lengths of caecum and appendix in Ⅰ-Ⅲ groups increase more repidly than the others. The surface projection of the appendix root draws down gradually following the descent of caecum.
