B型超声在小儿晚期阑尾炎诊断治疗上的应用

为了对小儿晚期阑尾炎的正确诊断，本文对177例小儿晚期阑尾炎进行了B超观察与分析。根据晚期阑尾炎的病理变化，显示出的各种声像图特征分为以下四型，其各有不同的治疗方法。（1）炎性浸润型；（2）部分液化浸润型；（3）完全液化脓肿型；（4）粪石穿孔阑尾周围炎型。其中Ⅰ型和Ⅱ型以保守药物治疗为主；Ⅲ型以穿刺抽脓治疗为主；Ⅳ型则行手术切除治疗。由于小儿不能与医生合作，常给诊断及治疗造成困难。本文资料表明B超对小儿晚期阑尾炎的诊断及指导治疗有极其重要的使用价值。

B-mode Ultrasonographic Diagnosis of Appendicitis in Children

In order to make a definite diagnosis of appendicitis in children, 177 affected children were examined by B-mode ultrasonography. Positive ultrasonographic features divided into four types:inflammatory infiltration type, partial colliquate infiltration type, abscess formation type, and fecalith-perforating appendicitis type. The demonstrated pictures were presented.
