目的探讨高频彩超联合低频彩超在非典型性急性阑尾炎诊断中的临床价值。方法回顾性分析深圳市龙岗区第三人民医院50例经病理证实的非典型性急性阑尾炎患者的影像学资料,所有患者术前均经高频、低频彩超检查,比较高频彩超联合低频彩超以及单纯高频彩超及低频彩超对于非典型性急性阑尾炎的诊断符合率,同时总结不同病理类型急性阑尾炎的超声声像图特征。结果经病理证实的50例非典型性急性阑尾炎患者中单纯性阑尾炎9例,化脓性阑尾炎30例,坏疽性阑尾炎11例。高频彩超联合低频彩超诊断符合率为94.00%;高频彩超诊断符合率为70.00%;低频彩超诊断符合率为62.00%。各组超声诊断与病理诊断符合率比较差异有统计学意义(P<0.01)。不同病理类型急性阑尾炎超声声像图特征存在明显差异。结论高频彩超及低频彩超图像各有优缺点,二者联合使用时可有效提高对非典型性急性阑尾炎的确诊率,值得临床推广应用。
Objective To investigate the clinical value of high frequency ultrasound and low frequency ultrasound in the diagnosis of atypical acute appendicitis. Methods The imaging data of 50 patients with pathologically confirmed atypical acute appendicitis from the Third People ’s Hospital of Longgang District were retrospectively analyzed. All patients were examined by high frequency and low frequency ultrasound before operation, and compared with high frequency ultrasound and low frequency ultrasound The diagnostic coincidence rate of simple high frequency ultrasound and low frequency ultrasound for atypical acute appendicitis, and summarize the ultrasonographic features of different pathological types of acute appendicitis. Results Pathologically confirmed in 50 cases of atypical acute appendicitis in patients with simple appendicitis in 9 cases, suppurative appendicitis in 30 cases, gangrenous appendicitis in 11 cases. The coincidence rate of high frequency color Doppler ultrasound and low frequency color Doppler ultrasound was 94.00%. The coincidence rate of high frequency color Doppler ultrasound diagnosis was 70.00%. The coincidence rate of low frequency color Doppler ultrasound diagnosis was 62.00%. The coincidence rate of ultrasonic diagnosis and pathological diagnosis in each group was significantly different (P <0.01). There were significant differences in the sonographic features of different pathological types of acute appendicitis. Conclusion High-frequency color Doppler ultrasound and low-frequency color Doppler ultrasound images have their own advantages and disadvantages. The combination of them can effectively improve the diagnosis of atypical acute appendicitis, which is worthy of clinical application.
