目的:进一步探讨B超诊断急性阑尾炎的影像分型特征和提高诊断符合率,避免误诊的体会。方法:应用迈瑞DP-7700型全数字化B超仪,7.5MHz和3.5MHz探头结合运用,高频扫查麦氏点纵切或压痛点为中心侧动探头观察急性阑尾炎165例病变的阑尾影像。结果:超声与临床诊断符合率为96.9%,误诊率为3.1%。结论:高频超声诊断急性阑尾炎影像分型特征明确,特异性高,化脓性和坏疽性阑尾炎超声诊断准确,利于尽早手术,对防止阑尾穿孔具有重要临床意义。
Objective: To further explore the B-ultrasound diagnosis of acute appendicitis imaging features and improve diagnostic accuracy, to avoid misdiagnosis experience. Methods: The appendix images of 165 patients with acute appendicitis were observed with Mindray DP-7700 digitalized B-ultrasound instrument, 7.5MHz and 3.5MHz probes combined with high-frequency scanning of Maxwell’s slits or tenderness points. Results: The coincidence rate of ultrasound and clinical diagnosis was 96.9%, the misdiagnosis rate was 3.1%. Conclusion: The diagnosis of acute appendicitis by high-frequency ultrasound is clear and specific. The ultrasonographic diagnosis of suppurative and gangrenous appendicitis is accurate, which is conducive to early surgery. It is of great clinical significance to prevent perforation of the appendix.
