高频超声诊断阑尾炎及分型的价值

The value of high - frequency ultrasound in diagnosis and typing of appendicitis

目的 探讨B超高频探头对阑尾炎的诊断及其分型。方法对30例阑尾炎患者进行B超高频探头检查。结果30例患者中26例经手术证实与B超高频探头检查相符合,4例经按阑尾炎治疗性诊断保守治疗均痊愈出院。阑尾炎声像图表现为:急性阑尾炎呈管状或手指状低回声;化脓性阑尾炎回盲部低回声增大,边界欠清;穿孔性阑尾炎回盲部及阑尾周围或盆腔内见不规则的液性暗区,部分病例内见沉淀物;阑尾周围脓肿,阑尾周围形成不均质团块回声。结论B超高频探头作为阑尾炎常规检查十分重要,既可以早期发现、早期明确诊断,还有利于早期治疗。

Objective To explore the value of high - frequency B ultrasound in diagnosis and typing of appendicitis. Methods Thirty patients with appendicitis were examined by high - frequency B ultrasound. Results Among 30 patients, operative evidences of 26 ones were in accordance with the finds of B ultrasound, the other 4 cured by conservative treatment according to appendicitis by the B ultrasound. Manifestations of acoustic image were 1) the low echo of tubular or fingerfor appendicitis;2)the enhancement of low echo at ileocecum and indistinct margin for suppurative appendicitis;3) fluid area opaca at ileocecum, around appendix or in pelvic cavity for perforative appendicitis;4)heterogeneous ball echo around appendix for periappendicular abscess. Conclusion It is very important that high - frequency probe of B ultrasound is as routine examination for appendicitis, which could early discover and diagnose appendicitis and is beneficial to early treatment.
