Abstract:
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.
