Abstract
Purpose
To evaluate the oncologic safety and surgical outcomes of endoscopic thyroidectomy (ET) performed via different surgical approaches for papillary thyroid carcinoma (PTC).
Methods
We reviewed the medical records of PTC patients who underwent ET between May 2015 and May 2021, at the Department of General Surgery, Beijing Friendship Hospital (affiliated with Capital Medical University). The patients were divided into three groups: the ET via breast approach (ETBA) group, the transoral ET vestibular approach (TOETVA) group, and the ET via transaxillary approach (ETTA) group. We evaluated the safety and surgical outcomes of each of these ET approaches.
Results
A total of 490 patients were included in the analysis: 416 in the ETBA group, 57 in the TOETVA group, and 17 in the ETTA group. There were no significant differences among the groups in clinicopathologic characteristics or surgical procedures, or in the incidences of complications such as hematoma, subcutaneous emphysema, infection, and chyle. The incidences of transient and permanent recurrent laryngeal nerve (RLN) injury were 1.4% and 4.3%, respectively, with no significant difference among the three groups. The incidences of transient and permanent postoperative hypoparathyroidism were 13.7% and 1.4%, respectively. The incidence of transient hypoparathyroidism in the TOETVA group was 1.7%, which was significantly lower than that in the ETBA group. The postoperative 1-, 3- and 5-year rates of disease-free survival were 99.5%, 96.8%, and 95.9%, respectively. Univariate and multivariate analyses showed that ET was not a significant risk factor for recurrence or metastasis (p = 0.83 and p = 0.49, respectively), regardless of the surgical approach.
Conclusions
TOETVA may be associated with a lower incidence of temporary hypoparathyroidism than ETBA. Apart from this difference, ETBA, ETTA and TOETVA showed comparable oncologic safety and surgical outcomes.
