摘要
本文报告使用10MHz高频探头在水浸法下扫查30例手术摘除的胆囊,观测胆囊壁在超声学上的构造。B超下胆囊壁显像为5层结构,其中第3层一条可清楚辨认的高回声带为浆膜下组织与肌层的交界线,并由组织学检查得到证明。由于癌肿浸润是否突破肌层是胆囊癌分期的重要指标之一,本研究结果表明,术中超声波高分辨率显像能够判定胆囊癌的进展程度和有助于外科医生选择合适的手术方式。
To observe sonographic structure of gallbladder wall, we examined 30 surgically removed gallbladders with 10 MHz transducer by water immersion method. The gallbladder wall was imaged as 5 layers. The layer 3, a well—defined hyperechoie zone, was confirmed histologically as corresponding to boundary between subserosa and rnuseularis. Since gallbladder cancer which whether or not spread beyond the mucle coat is a significant indicator for staging the carcinoma, the present study shows high resolution images may well be used in judgement the stage of gallbladder cancer by introperative ultrasond, enabling surgeon to choose proper operative procedure.
