【摘要】 目的探讨急性阑尾炎的超声间接征象阳性率、声像图表现、与炎症程度的关系及其临床意义。方法应用彩超检查160例急性阑尾炎患者,分析其间接征象。结果 (1)急性阑尾炎时超声间接征象局部探头压痛及反跳痛阳性率较高(96.3%)、回盲部水肿(75.6%)、右下腹局部强回声(36.9%)。(2)超声间接征象与手术病理结果一致性较好(P<0.01)。(3)超声间接征象阳性率与阑尾炎病理类型有关(P<0.01),阑尾炎越严重,阳性率越高。结论超声间接征象能确切反映阑尾周围组织炎症,其阳性率与炎症程度有关,正确认识超声间接征象,有助于临床对急性阑尾炎的诊断。更多还原

【Abstract】 Objective To study the positive rate and acoustic image of indirect ultrasound signs of acute appendicitis, the relation to inflammation severity and the clinical significance.Methods 160 acute appendicitis samples were inspected with color Doppler imaging and indirect symptoms were analyzed.Results(1) The positive rate of the indirect signs:local probe tenderness and rebound tenderness(96.3%);ileocecum edema(75.6%);local strong echo right lower quadrant(36.9%).(2) The inspection result is identical with operation pathological result(P<0.01).(3) The positive rate of the indirect signs is related to the pathology type of appendicitis(P<0.01),the severe th appendicitis, the higher is the positive rate.Conclusions Ultrasonic indirect signs reflect the inflammation of appendix’s surrounding tissues.The positive rate is related to the inflammation severity.A correct understanding of indirect ultrasono- graphic signs helps to diagnose the acute appendicitis clinically.更多还原
