[Ultrasonic diagnosis of clonorchiasis sinensis]

This is to retrospectively review and summarize the ultrasonic images of 214 patients who were diagnosed as clonorchiasis and received treatment. The major changes in ultrasonography were found in gallbladder and hepatic bile duct. Flocculent echos in the gallbladder were the characteristic feature, which disappeared after chemotherapy. The wall of hepatic bile duct became thicker and shaggy in most patients. These changes improved quite slowly after treatment. Ultrasonography is of value in the diagnosis of clonorchiasis sinensis
