Abstract:
Objective To analyze the clinical value of high frequency combined with low-frequency ultrasound examination for the diagnosis of acute appendicitis.Methods From September 2015 to September 2016,150 patients with suspected acute appendicitis in the Traditional Chinese Medicine Hospital of Beilun District were selected in the research,the low frequency combined with high frequency ultrasound examination was performed.The diagnostic accuracy of high frequency combined with low frequency ultrasound for patients with acute appendicitis was compared with postoperative pathological findings.Results The diagnostic accuracy of high frequency combined with low frequency ultrasound for periappendicural abscess,simple appendicitis,suppurative appendicitis,gangrenous appendicitis was 95.5％,94.4％,97.8％,97.9％,respectively.The diagnosis accuracy of high frequency combined with low frequency ultrasound for acute appendicitis at prepositional ileum,basin,upward behind cecum,behind ileum was 97.4％,97.6％,97.1％,93.8％,respectively.The accuracy,specificity,sensitivity,the missed diagnosis rate and misdiagnosis rate of high frequency combined with low frequency ultrasound in the diagnosis of acute appendicitis were 96.9％,90.0％,96.9％,3.1％,10.0％,respectively,and compared with the results of postoperative pathologic examination,there were no statistically significant differences(all P ＞ 0.05).Conclusion High frequency combined with low frequency ultrasound in the diagnosis of acute appendicitis has high diagnostic accuracy.
