Abstract
ObjectiveTo compare the effect of layer dissection and traditional management in total thyroidectomy by comparing the levels of parathyroid hormone and calcium after operation.
MethodsFrom January 2019 to June 2019, a total of 120 patients who underwent total thyroidectomy were retrospectively analyzed, in including 96 females and 24 males, aged from 24 to 72 years old, with the average of 52 years. There were 63 cases in layer dissection group and 57 cases in traditional management group. The main index was the level of parathyroid hormone and blood calciumon the 1st day after operation. The measurement data of non normal distribution were described by quartile [M(P25, P75)]. T-test or nonparametric test were used for comparison between groups. The chi-square was used to conduct comparison between count data of groups.
ResultsOn the first day after operation, the serum calcium level in the layer dissection group was significantly higher than that in the traditional management group, with a median of 2.15 mmol/L and 2.10 mmol/L, respectively (Z=-2.019, P=0.043). The level of parathyroid hormone in layer dissection group was significantly higher than that in traditional management group [23.8 (16.2~34.8) pg/mL vs 15.3 (8.9~29.0) pg/mL, Z=-3.646, P<0.001]. The incidence of postoperative complications in the layer dissection group was lower than that in the traditional management group (6.3%vs 21.1%, χ2=5.599, P=0.018). One month after operation, the results of blood calcium and parathyroid hormone were both normal [blood calcium 2.31 (2.23~2.41) mmol/L vs 2.32 (2.26~2.37) mmol/L, Z=-0.657, P=0.648 and parathyroid hormone 37.6 (32.3~51.1) pg/m vs 35.8 (27.7~48.9) pg/mL, Z=-0.674, P=0.499], and there was no significant difference between the two groups.
ConclusionThe layer dissection method for the superior pole thyroid capsule, compared with traditional management, can reduce the incidence rate of postoperative hypocalcemia and the incidence rate of postoperative complications, can improve the quality of patients′ life.
