Abstract
ObjectiveTo compare the diagnostic efficiency of colloidal gold dipstick method (PTH dipstick method) with that of doctors’ experience method based on nano-carbon method for rapid identification of parathyroid gland in thyroidectomy of thyroid cancer.
MethodsFrom March to July 2020, 90 patients underwent thyroid surgery in the Friendship Hospital, Capital Medical University participated in the experimental study, and 155 samples underwent empirical judgment, parathyroid dipstick and pathological examination. All operations were performed by senior specialists. SPSS statistics 17.0 software was used for statistical analysis.
ResultsSeventy-four cases of parathyroid gland confirmed by both pathology and empirical judgment, and 81 cases of non-parathyroid gland confirmed by pathology; 130 cases of parathyroid glands confirmed by both PTH dipstick method and pathology, and 22 cases of non-parathyroid glands confirmed by pathology. The accuracy rate of PTH dipstick method was 85.53% which was much higher than that of empirical judgment method (47.74%). The data were statistically significant (χ2=49.14, P<0.05). The sensitivity of PTH method was 95.89%, the specificity of PTH method was 75.94%, and the Youden index was 0.7183. The sensitivity of empirical judgment method was 81.3%, the specificity of empirical judgment method was 47.74%, and the Youden index was 0.2904.
ConclusionsThe diagnostic efficiency of the PTH method is higher than that of empirical judgment method to identify parathyroid gland in thyroid surgery. The two methods can be used together to increase the protection of parathyroid gland during operation.
