The impact of gasless insufflation transaxillary endoscopic thyroidectomy on the parathyroid gland injury in patients with thyroid cancer: a retrospective analysis

Recently, endoscope has been widely used in thyroid surgery and gasless insufflation transaxillary endoscopic thyroidectomy (GTET) has been the mainstay of thyroid surgery. Parathyroid gland (PG) damage is a common complication of thyroid surgery. Therefore, the aim of this study was to investigate the effect of GTET on hypoparathyroidism (HPT) in patients with thyroid cancer. According to the surgical approach, the patients were divided into a GTET group and a conventional open thyroidectomy (COT) group. Univariate analysis and logistic regression were used to identify factors associated with PG injury. The odds ratio (OR) and 95% confidence interval (CI) for each independent variable were calculated. A retrospective analysis was conducted on 405 patients diagnosed with papillary thyroid cancer (PTC). A total of 51 patients experienced PG injury, including 7 cases (5%) of GTET group and 44 cases (16.5%) of COT group (P
