急性阑尾炎超声声像图与病理分型比较

Comparision of acute appendicitis ultrasonography and pathological types

目的探讨超声诊断急性阑尾炎与病理分型的符合率。方法对2009年7月—2010年6月间经手术和病理证实的急性阑尾炎患者106例超声声像图特征的临床资料进行回顾性分析,探讨超声检查对急性阑尾炎的价值。结果本组106例中,通过声像图改变而确诊为急性阑尾炎者93例(87.7%),无声像图改变13例(12.3%)。急性单纯性阑尾炎7例假阴性;急性化脓性阑尾炎手术发现5例假阴性;坏疽性阑尾炎1例漏诊;阑尾周围脓肿12例,超声诊断全部符合,说明超声对阑尾周围脓肿诊断特异性高。结论彩色多普勒超声诊断急性阑尾炎方法有效,熟悉各型阑尾炎影像特点,可为临床诊断和鉴别诊断提供重要依据。

Objective To discuss the compliance rate of ultrasound diagnosis of acute appendicitis and pathological pattern.Methods Retrospective analysis of the samples in July 2009-June 2010 confirmed by surgery and pathology between the acute appendicitis patients with sonographic features of 106 patients the clinical data of ultrasound in acute appendicitis.Results Among 106 patients in this group,93 cases（87.7%）were diagnosed as acute appendicitis by sonographic changes,13 patients（12.3%） without sonographic changes.7 cases of acute simple appendicitis were found false negative;5 cases of acute suppurative appendicitis false negative;1 case of gangrenous appendicitis misdiagnosed;12 cases of appendiceal abscess were all in compliance with ultrasound,indicating a high specificity with ultrasound diagnosis of appendix abscess.Conclusions Color Doppler ultrasound diagnosis of acute appendicitis was identified effective,and to be familiar with the imaging features of various types of appendicitis will provide an important basis for clinical diagnosis of differential types of appendicitis.
