摘要
目的 探讨应用3.5MHz探头诊断急性阑尾炎的方法和临床价值。方法 分析15年来随着超声医师对盲肠和阑尾解剖结构及声像图特征认识的深化、扫查技术的改进,使急性阑尾炎的诊断水平不断提高。本组120例B超诊断经手术病理证实的急性阑尾炎病例作为分析研究的对象。结果 早期(1986～1993年)抽取35例,超声诊断率为71.4％;近期(1993～2002年10月)病例抽取85例,超声诊断率为91.5％,两者有显著性差异。结论 正确认识盲肠与阑尾声像图特征是诊断急性阑尾炎的关键所在,普通超声诊断仪用3.5MHz探头能用于急性阑尾炎的诊断,为临床提供可靠的依据。
Objective To discuss the method of diagnosis acute appendicitis and its clinical value by using 3.5MHz ultrusound transducer. Methods Since the improvement of imaging quality, anatomical knowledge of appendix and method of examination in recent 15 years the diagnostic accuracy was improved markedly. This study was based upon 120 cases of pathological proved which were diagnoed by ultrasound preoperatively. Results During 1986-1993, the diagnostic rate of ultrasonography was 71.4% among 35 cases .In contrast the diagnostic rate was 91.5% among 85 cases during 1993-2002. There was significanted difference between the two series. Conclusion To understand sonographic features of caecum and appendix is the key for diagnosing acute appendicitis. Conventional ultrasound system with 3. 5MHz transducer can afford diagnosing acute appendicitis .
