0～14岁儿童正常阑尾超声下长度及外径分析

目的通过超声测量不同年龄(0~14岁)儿童正常阑尾的长度和外径,评估正常阑尾长度、外径与儿童年龄、身高及体重等因素的相关关系。方法选择2015年1月至2015年5月在本院健康体检并排除阑尾炎及影响阑尾测值因素的儿童,用彩色超声仪探查阑尾情况,完整显示阑尾全长,按年龄、体重、身高等分别统计儿童阑尾的长度、外径,并进行相关性分析,分析患儿年龄、体重、身高与阑尾长度、外径之间的关系。结果 205例中,阑尾长度及外径分别为(36.33±8.27)mm、(4.01±2.83)mm,长度与外径呈正态分布,阑尾的长度与年龄、身高及体重有相关性,P值均0.05(相关系数分别为r=0.039,0.022,0.037),阑尾的外径与年龄、身高无明显相关性,P值均0.05(r=0.151,0.590),与体重有相关性,r=0.025,P0.05。结论阑尾长度随年龄、身高及体重的变化而改变,阑尾外径直径与年龄、身高无明显相关,但会受儿童体重的影响。

Ultrasonic measurements of normal appendix in children and its relationship with age,height and ;weight

Objective To measure the appendiceal length and diameter of children by ultrasonography and assess the relationship of normal appendiceal length and diameter with patient-specific factors. Method-s Ultrasonic examinations were performed for 205 pediatric patients with normal appendixes.Appendiceal length and diameter were correlated with patient age,gender,height and weight. Results The mean appen-diceal length and diameter were 36.33 ±82.7 and 4.01 ±2.83 mm respectively.Appendiceal lengths and di-ameters were normally distributed across the population.Appendiceal length was significantly correlated with age,height and weight.Appendiceal diameter was only significantly associated with weight but it was not sig-nificantly associated with age or height. Conclusions The ultrasonic measurements of appendiceal diameter are normally distributed in children and it is not dependent on age but influenced by weight.
