This study aimed to determine the incremental value of using a structured report (SR) for US examinations of the pediatric appendix.
Between January 2009 and June 2016, 1150 pediatric patients with suspected appendicitis who underwent US examinations of the appendix were included retrospectively. In November 2012, we developed a five-point scale SR for appendix US examinations. The patients were divided into two groups according to the form of the US report: free-text or SR. The primary clinical outcomes were compared between the two groups, including the rate of CT imaging following US examinations, the negative appendectomy rate (NAR), and the appendiceal perforation rate (PR).
In total, 550 patients were included in the free-text group and 600 patients in the SR group. The rate of additional CT examinations decreased by 5.3% in the SR group (8.2%, = 0.003), and the NAR decreased by 8.4% in the SR group (7.8%, = 0.028). There was no statistical difference in the appendiceal PR (37.6% vs. 48.0%, = 0.078).
The use of an SR to evaluate US examinations for suspected pediatric appendicitis results in lower CT use and fewer negative appendectomies without an increase in appendiceal PR.
本研究旨在确定使用结构化报告（SR）进行小儿阑尾超声检查的增量价值。
回顾性纳入2009年1月至2016年6月期间1150例疑似阑尾炎且接受阑尾超声检查的儿科患者。2012年11月，我们制定了用于阑尾超声检查的五点量表SR。根据超声报告的形式将患者分为两组：自由文本组或SR组。比较两组的主要临床结局，包括超声检查后CT成像率、阴性阑尾切除率（NAR）和阑尾穿孔率（PR）。
自由文本组共纳入550例患者，SR组纳入600例患者。SR组额外CT检查率降低了5.3%（8.2%，P = 0.003），SR组NAR降低了8.4%（7.8%，P = 0.028）。阑尾PR无统计学差异（37.6%对48.0%，P = 0.078）。
使用SR评估疑似小儿阑尾炎的超声检查可降低CT使用率和阴性阑尾切除率，且不增加阑尾PR。
