Gasless endoscopic thyroidectomy via the anterior chest approach: the experience with 1500 cases

Conventional thyroidectomy leaves an eye-catching scar in the anterior neck region. Endoscopic thyroidectomy may achieve a better esthetic effect and improve quality of life postoperatively. The aim of this study was to undertake a complete review of a large cohort of the patients undergoing gasless endoscopic thyroidectomy (GET) via anterior chest approach (ACA) with a long-term follow-up period, and evaluate the results and limits of this procedure.

Between 2003 and 2022, 1413 patients undergoing GET via ACA in our department were included. The demographic, clinicopathological characteristics, oncologic and esthetic outcomes were summarized and analyzed.

The indication for surgery was papillary thyroid carcinoma in 686 (48.5%) patients and benign thyroid diseases in 727 (51.5%) patients. Among them, 802 (56.8%) patients took hemithyroidectomy, and 611 (43.2%) patients did sub-total/total thyroidectomy. Meanwhile, 598 (42.3%) ones had central neck dissection, while 88 (6.2%) lateral neck dissection. The most common complication was transient hypoparathyroidism with an incidence of 2.9%. During the follow-up period of 2 to 232 months, three patients were confirmed locoregional recurrence. Most of the patients were satisfied with the cosmetic results.

Gasless endoscopic thyroidectomy via anterior chest approach is a safe and feasible procedure, which could achieve excellent oncologic and esthetic outcomes.
