Objective To evaluate the safety and efficacy of gasless endoscopic thyroidectomy via transaxillary approach in treating papillary thyroid cancer (PTC). Methods The patients who underwent gasless endoscopic thyroidectomy (Abbreviated as the “endoscopic group”) and neck open surgery (Abbreviated as the “open group”), in the Zhejiang Provincial People’s Hospital from January 2018 to June 2023, were collected. The intraoperative and postoperative outcomes of the patients in the two groups were compared after propensity score matching (PSM). Statistical analysis was conducted using SPSS 26.0 software, with a test level of α=0.05. Results After PSM, there were 409 patients in the endoscopic group and 421 patients in the open group. There were no statistically significant differences in the baseline data between the two groups (P>0.05), except for tumor location, vascular invasion, intraglandular dissemination, and preoperative levels of total triiodothyronine and thyroid hormone (P<0.05). Compared with the open group, the patients in the endoscopic group had less intraoperative blood loss (P<0.05), more lymph nodes dissected (P<0.05), higher points of incision satisfaction and cosmetic effect (P<0.05). The incidence of postoperative overall complications had no statistically significant difference between the endoscopic group and open group (3.6% versus 5.8%, P>0.05). There was no statistically significant difference in the recurrence rate between the endoscopic group and open group within one year of follow-up (0.2% versus 0.5%, P>0.05). Conclusions From the results of this study, the gasless endoscopic thyroidectomy is safety and reliability for PTC treatment. It can achieve the same effect as traditional open thyroidectomy. However, it can also be seen that young female patients are more willing to choose gasless endoscopic thyroidectomy as long as their condition permits (such as early tumor stage, low invasiveness).
