Abstract:
Objective:To investigate the feasibility and clinical significance of near-infrared fluorescence positive imaging combined with intraoperative rapid parathyroid hormone (PTH) determination in identification and function protection of the parathyroid gland during thyroidectomy.Methods:According to the inclusion and exclusion criteria, patients in the Affiliated Lihuili Hospital of Ningbo University, who needed bilateral thyroidecto-my and central lymph node dissection due to suspected bilateral thyroid cancer from Mar. 2020 to Oct. 2020 were selected for a prospective clinical study. They were randomly divided into the study group (near-infrared fluorescence positive imaging combined with intraoperative rapid PTH determination) and the control group (intraoperative experience identification) . The number of parathyroid glands found during operation, PTH before and after the operation, blood calcium, blood phosphorus, the presence of parathyroid tissues in routine pathological section examinations, and postoperative symptoms were collected. SPSS 25.0 statistical software was used for analysis, the measurement data were expressed by mean±standard deviation ( ± s) , t test was used for comparison between groups, and χ2 test was used for counting date. Results:In the study group of 33 cases, 135 suspicious parathyroid glands were exhibited during operation, with an average of (4.09±0.52) ; Hand and foot numbness occurred in 1 case (3.03%) ; On the 1st after the operation, PTH was (23.68±9.48) ng/L. In the control group of 31 cases, 109 parathyroid glands were identified by naked eyes, with an average of (3.52±0.63) ; Hand and foot numbness occurred in 6 cases (19.35%) ; On the 1st after the operation, PTH was (17.93±11.58) ng/L. The differences were statistically significant ( P<0.05) . But no statistical significance was found in operation duration (79.45±30.18) min, postoperative hospitalization days (5.85±2.27) days, PTH (27.10±9.80, 33.08±10.21) ng/L, blood calcium (2.11±0.10,2.25±0.09) mmol/L, and blood phosphorus (1.20±0.20,1.15±0.12) mmol/L on the 3rd day and the 6th month after the operation. Conclusion:Near-infrared fluorescence positive imaging combined with intraoperative rapid PTH determination can improve the recognition rate of the parathyroid gland and reduce postoperative complications, which is a safe, effective and rapid method for intraoperative parathyroid gland recognition.
