Comparison of ultrasound contrast and conventional ultrasound guided superficial lymph node biopsy / 中国基层医药

ABSTRACT

Objective To study the difference between ultrasound contrast and conventional ultrasound guided superficial lymph node biopsy.Methods The patients who received superficial lymph node biopsy were randomly divided into observation group (40 cases)and control group (40 cases),the patients were divided into the observation group and the control group.In the control group,conventional ultrasound was used to guide.Patients in the observation group were guided by ultrasound contrast.Specimens of pathological satisfaction rate,diagnostic accu-racy rate and the recovery rate of patients between two groups were compared.Results The pathological satisfaction rate of the control group was 83.2%,the observation group was 96.9%,and the difference between the two groups was statistically significant(χ2 =3.95,P <0.05).The diagnostic accuracy rate of the control group was 82.5%,the observation group was 95.0%,the difference between the two groups was statistically significant(χ2 =4.26,P <0.05).The recovery rate of the control group was 87.5%,and the recovery rate was 97.5% in the observation group, and the difference was statistically significant(χ2 =6.71,P <0.05).Conclusion Compared with conventional ultra-sound,ultrasound imaging has a greater advantage in guiding superficial lymph node biopsy.
