Abstract:
Objective To compare the value of conventional ultrasound,hydrosonography and double-contrast enhanced ultrasound in the display capacity of periampullary carcinoma and its relationship with the surrounding tissue.Methods A total of 18 patients with the periampullary carcinoma were diagnosed pathologically or by endoscopic biopsy.Each patient had three imaging modalities by conventional ultrasound,hydrosonography and double-contrast enhanced ultrasound.The display capacity and the relationship between the mass and surrounding tissue were compared with three modalities.Results The display rates of limpid visibilities of carcinoma on conventional ultrasound,hydrosonography and double-contrast enhanced ultrasound were 16.7%(3/18),22.2%(4/18) and 94.4%(17/18),respectively;The display rates of duodenum protrusion on three modalities were 0(0/18),38.9% (7/18) and 72.2% (13/18),respectively,with significant differences among conventional ultrasound,hydrosonography and double-contrast enhanced ultrasound.The double-contrast enhanced ultrasound showed two cases of peripheral vascular invasion and one case of intrahepatic metastasis.Conclusion The double-contrast enhanced ultrasound can increase the display capacity of periampullary carcinoma as a new diagnostic modality for periampullary carcinoma.
