Abstract:
Objective To investigate the value of oral and intravenous contrast enhanced ultrasonography-double contrast ultrasonography (DCUS) in the evaluation of differentiation degree of gastric cancer. Methods Fifty-three patients who had been diagnosed as gastric cancer by gastroscope and confirmed by pathology after operation were examined by DCUS, and they were divided into moderately to well differentiated group and poorly differentiated group. The correlation of size and enhancement features of the lesions was compared with differentiation degree of gastric cancer. Results The size and enhancement distribution of lesions were markedly correlated with the degree of differentiation. The baseline intensity(BI)in poorly differentiated group was lower than that in well and moderately differentiated group[(0.52±1.12)dB vs (1.53±1.87) dB, P<0.05], but enhanced intensity(EI) was higher than that in the second group [(26.22±3.69)dB vs (23.69±5.02)dB, P<0.05]. Conclusions DCUS could initial evaluate the degree of differentiation of gastric cancer before operation.
