目的 探讨高频超声及彩色多普勒血流显像 (CDFI)对小儿急性阑尾炎的诊断价值。方法 应用高频超声及彩色多普勒血流显像诊断小儿急性阑尾炎 12 6例 ,均经手术病理证实 ,对各型小儿急性阑尾炎的声像图特征进行回顾性分析。结果 12 6例小儿急性阑尾炎全部经手术病理证实 ,术前超声检出 114例 ,超声检出率90 .5 % (114 / 12 6 ) ,未检出 12例 ,占 9.5 % (12 / 12 6 )。术前超声分型与术后临床病理分型相符 10 5例 ,符合率92 .1% (10 5 / 114 ) ,其中急性单纯性阑尾炎符合率 89.1% (41/ 4 6 ) ,急性化脓性阑尾炎符合率 92 .2 % (47/5 1) ,坏疽性及穿孔性阑尾炎符合率 10 0 % (11/ 11) ,阑尾周围脓肿符合率 10 0 % (6 / 6 )。结论 高频超声不受小儿腹壁厚度的影响 ,结合彩色多普勒血流显像 ,对小儿急性阑尾炎的诊断及分型符合率高 ,可为临床早期制订治疗方案提供重要依据。
Objective To explore the clinical diagnostic value of high frequency ultrasound and color Doppler flow imaging(CDFI)in children's acute appendicitis.Methods A total of 126 cases of children with acute appendicitis were diagnosed with high frequency ultrasound and CDFI and the characteristics of different types of children's acute appendicitis were analysed respectively.Results All 126 children with acute appendicitis were confirmed by operation,in which 114 cases were diagnosed by ultrasound before operation and the ultrasound diagnosis rate was 90.5%(114/126),and 12 cases failed to be diagnosed and the missed diagnosis rate was 9.5% (12/126).Of 126 cases,105 cases with different types were coincident betweent ultrasound before operation and clinical pathologic diagnosis after operation.The coincident rate was 92.1%(105/114),in which the coincident rate of acute simple appendicitis was 89.1%(41/46),acute suppurative appendicitis was 92.2%(47/51),gangrene and perforated was 100%(11/11)and appendicular abscess 100%(6/6).Conclusions High frequency ultrasound has good penetration,so it is not under the influence of children's abdominal wall thickness.Combined with CDFI,high frenquency ultrasound has high conicident rate for diagnosis and differentiation of various types of appendicitis.
