A study on the safety and efficacy of endoscopic thyroidectomy via axillary approach for the treatment of thyroid cancer.

ABSTRACT

This study aims to evaluate the safety and efficacy of endoscopic thyroid cancer treatment using an axillary approach. Participants were allocated into 2 groups one undergoing transaxillary endoscopic surgery and the other, traditional open surgery. We compared intraoperative and postoperative conditions, focusing on parameters such as intraoperative blood loss, duration of surgery, length of postoperative hospitalization, volume of postoperative drainage, number of lymph nodes cleared in the central region, neck pain scores, neck injury indices, cosmetic satisfaction, postoperative complications, and total hospitalization duration. Patients in the endoscopic treatment (ET) group experienced longer surgical times, less intraoperative bleeding, and increased postoperative drainage. These indicators showed significant differences between the groups (P < .05). For the group undergoing endoscopic surgery via the axillary approach, there was a lower neck pain score on the third postoperative day and higher cosmetic satisfaction at 3 months. However, there were no significant differences between the groups in terms of the number of lymph nodes cleared in the central area, and the incidence of complications such as difficulty breathing, difficulty swallowing, hoarseness, and subcutaneous hematoma (P > .05). The axillary approach endoscopic surgery group also showed significantly prolonged surgery times and postoperative hospital stays, with a significant increase in postoperative drainage fluid (P < .05). Concurrently, this technique involved smaller surgical incisions and effectively concealed scars in the armpit, leading to better outcomes in terms of intraoperative bleeding, neck pain scores, and postoperative cosmetic satisfaction. Non-inflatable ET via the axillary approach for treating thyroid cancer demonstrates promising efficacy and safety. It offers additional benefits of minimal pain and enhanced cosmetic outcomes, making it a viable option for clinical adoption and application.
