术前超声诊断急性阑尾炎临床类型的探讨

Discussion on Diagnosis of Clinical Classification of Acute Appendicitis with Ultrasound before Operation

目的分析正常阑尾与病变阑尾的超声表现,探讨超声术前确定急性阑尾炎临床类型的价值。方法141例经手术证实的急性阑尾炎患者,年龄6～81岁,女59例,男62例。结果83例急性单纯型阑尾炎超声表现阑尾增粗,横断管径7～10mm。31例急性化脓性阑尾炎增粗阑尾管径11～16mm,且阑尾管腔呈中等均匀回声。27例坏疽及穿孔性阑尾炎,超声表现较复杂,18例呈球形杂乱回声,以中等回声为主,且多为厚度一致回声,9例患者病变中央可见多少不等液性无回声信号。经统计学处理,术前超声确定急性阑尾炎临床类型与术后结果密切相关(P=0.005)。结论超声检查术前确定急性阑尾炎临床类型具有相当的准确程度。

Objective To analyze the manifestation of normal and lesion appendix of ultrasound and discuss the diagnostic value before operation of acute appendicitis type with ultrasound. Methods The clinical data of 141 cases who were obtained with operation were analyzed in age from 6～81 years old with female 50 cases and male 62 cases. Results There were 83 cases acute simple appendicitis with large caliber at diameter of 7～10 mm. There were 31 cases acute suppurative appendicitis with diameter of 11～16 and iso-echo. There were 27 cases gangrenous and perforated appendicitis with complex manifestation. There were 18 cases with ball like irregular echo and 9 cases with liquid echo at central location. There was closed relationship with the diagnosis with ultrasound and results after operation of acute appendicitis (P=0.005). Conclusion The might be relative accuracy on diagnosis of acute appendicitis eith ultrasound.
