To stratify ultrasound samples in a pediatric population undergoing evaluation for acute appendicitis to examine the variability in cecal appendix diameter, in different age groups, and to determine whether there is a prevalent value for each age group.
A retrospective cross-sectional study with 196 children aged 0 to 15 years. Data were extracted from reports of ultrasound examinations carried out between 2008 and 2015. Children with sonographic diagnosis of appendicitis or other signs of periappendiceal inflammation were excluded.
The evaluation of the anteroposterior measurement of the cecal appendix revealed a mean diameter of 4.14mm (standard deviation: 0.93mm; 95%CI: 3.86-4.14). Cecal appendix diameter did not differ significant between age groups.
Evaluation of the anteroposterior diameter of the cecal appendix in centimeters in a sample of 196 children aged 0 to15 years revealed a mean diameter of 4.14mm (standard deviation, 0.93mm. There were no significant differences in cecal appendix diameter following stratification by age. Results indicate a single value can be adopted for mean cecal appendix diameter in pediatric populations.
对接受急性阑尾炎评估的儿科人群的超声样本进行分层，以检查不同年龄组盲肠阑尾直径的变化，并确定每个年龄组是否存在常见值。
这是一项回顾性的病例对照研究，共纳入 196 名 0 至 15 岁的儿童。数据来自 2008 年至 2015 年进行的超声检查报告。排除了超声诊断为阑尾炎或其他阑尾周围炎症迹象的儿童。
对盲肠阑尾前后径的评估显示平均直径为 4.14mm（标准差：0.93mm；95%CI：3.86-4.14）。不同年龄组之间盲肠阑尾直径无显著差异。
对 196 名 0 至 15 岁儿童的盲肠阑尾前后径进行评估，结果显示平均直径为 4.14mm（标准差，0.93mm）。根据年龄分层，盲肠阑尾直径无显著差异。结果表明，在儿科人群中可以采用单个均值来表示盲肠阑尾直径。
