摘　　要：目的探讨急性阑尾炎(acute appendicitis,AA)及急性感染性肠炎(acute infectious enteritis,AIE)患儿的阑尾高频超声影像特点及其显像敏感性。方法回顾性分析临床确诊为急性阑尾炎患儿120例,急性感染性肠炎患儿160例,并对其行高频超声检查,另设120例正常儿童为对照组。分析高频超声阑尾显示率,阑尾外径,阑尾周围系膜炎性变化以及阑尾的位置等情况。结果 AA组、AIE组、对照组阑尾的显示率分别为96.7%、80.6%、68.3%,差异有统计学意义(P<0.05)。三组超声显示的阑尾外径分别为(8.5±2.2)mm、(4.3±0.8)mm、(3.5±0.7)mm,相互间差异亦均有统计学意义(P<0.05)。AA组所有的阑尾周围系膜炎症改变均可探及,但AIE组的阑尾周围系膜无变化。结论小儿急性阑尾炎高频超声显像敏感性高,旨在为临床对AA早期诊断、早期治疗提供较准确全面的影像学依据。Objective Use high-frequency ultrasound to determine the frequency of visualization and image feature of the appendix in children with acute appendicitis （ acute appendicitis, AA） and with acute infectious enteritis （ acute infectious enteritis, AIE）. Methods The ultrasonic features of 120 children with AA, 160 children with AIE, and 120 randomly select- ed asymptomatic children were analyzed retrospectively. And their visualization rate, outer appendiceal diameter, presence or ab- sence of inflamed periphery appendiceal mesenterium, and location of the appendix were recorded. Results The visualization rates of the appendix were 96.7% , 80. 6%, and 68.3% for AA groups, AIE groups, and the control, respecfively（P 〈0. 05）. The outer appendiceal diameters for the 3 groups were （ 8.5 ± 2.2） ram, （4. 3± 0. 8 ） mm, and （ 3.5 ± 0. 7 ） ram. Difference among the 3 groups was statistically significant also. Periphery appendiceal inflamed mesenterium was detected in all AA cases, but in none of the AIE cases. Conclusion High ultrasound imaging sensitivity of puerile acute appendicitis provided relatively accurate comprehensive imaging basis for clinical early diagnosis and early treatment.
