本文前瞻性研究以确定继发于头孢三嗪(ceftri-axcone)的胆管并发症的发病率及演变情况,并描述了假性胆管结石的超声表现。 30例经头孢三嗪治疗的严重感染的患者(平均3.1岁)进行一系列超声检查。总共超声检查68次。结 果发现胆管假结石12例(40％),其中有症状1例。停用头孢三嗪后,假结石于2～30d逐渐消失。超声检查时头孢三嗪引起的假结石不易与典型的胆管结石区别。超声表现为泥沙状至大结石声学阴影。 This prospective study was conducted to determine the incidence and evolution of biliary complications secondary to ceftri-axcone and to describe the ultrasound findings of pseudo-bile duct stones. Thirty patients with severe infections treated with ceftriaxone (mean 3.1 years) underwent a series of ultrasonography. A total of 68 ultrasound examinations. Results found that bile duct stones in 12 cases (40%), of which 1 case of symptoms. Ceftriaxone disabled, fake stones in 2 ~ 30d gradually disappear. Cecum triphosphate caused by pseudocarbons is not easy to distinguish the typical bile duct stones. Ultrasound showed silt to large acoustic acuity shadow.
