目的分析药物性胆囊结石的超声特点。方法采用飞利浦M2540、飞利浦IU-22对15例使用头孢曲松钠致胆囊结石患者进行多切面扫查,随访结石变化。结果药物性胆囊结石多产生于用药后5~10 d,声像图大致呈泥沙型、团块型、悬浮型三种类型,结石数目不等、大小不一、后方可无声影,随体位改变可移动或变形,停药后10~60 d结石明显变小或完全消失。结论静脉应用头孢曲松钠后产生胆囊结石,与一般胆固醇结石相比,不具有特异性声像图特征,停药后短期内可恢复正常,应针对其病史及随诊情况与传统胆囊结石鉴别。
Objective To analyze the ultrasonic characteristics of drug-induced gallstone. Methods Multi-slice scanning was performed in 15 patients with cephothyronin-induced gallbladder stones by using Philips M2540 and Philips IU-22. The stones were followed up. Results The drug-induced gallstones were mostly produced 5 to 10 days after treatment. The sonography showed roughly three types: sediment type, clump type and suspension type. The numbers of stones ranged from one to another. Changes can move or deformation, 10 ~ 60 d after stopping the stone was significantly smaller or completely disappear. Conclusion Intravenous ceftriaxone sodium produces gallbladder stones, compared with the general cholesterol stones, does not have specific sonographic features, short-term recovery may return to normal, should be based on their history and follow-up and traditional gallstones identification .
