Background:
Due to technical challenges, single-site endoscopic thyroidectomy (SSET) is seldom reported and has been attempted in only limited cases. This large-scale study aimed to compare the clinical outcomes of standardized transareola SSET (TASSET) with those of conventional open thyroidectomy (COT) for thyroid cancer.
Methods:
The data were prospectively collected, and case-match study was performed at a ratio of 1:1 according to age, sex, body mass index, lesion size, number of lesion foci, lesion side, recurrent laryngeal nerve (RLN) exploration and pathology. Two hundred eligible patients underwent TASSET, and the same number of patients was selected for propensity score matching from 2256 patients who underwent COT. Perioperative data, including surgical profile, oncological and traumatic burdens, and cosmetic satisfaction, were analyzed.
Results:
No significant differences were observed in blood loss or drainage between TASSET and COT groups. There were no differences in operation time between TASSET and COT (106.39 ± 28.44 vs 102.55 ± 23.10 min, p = 0.154). A total of 3.63 ± 1.82 lymph nodes (LNs) were retrieved from CND with 0.96 ± 1.42 positive in TASSET. In COT, the total and positive LN yields were 3.77 ± 1.91 and 0.99 ± 1.40 (p = 0.445, p = 0.802). Cancer recurrence was not observed in either group. There were no differences in the occurrence of permanent and transient hoarseness or RLN injuries. Postoperative flap seroma or hematoma occurred in 12 TASSET patients and 58 COT patients (p < 0.001). The pain score, CRP level and ESR in TASSET group were lower than those in COT group. TASSET yielded significantly better incision recovery and cosmetic scores than did COT at both the proliferation and stabilization stages.
Conclusions:
TASSET is technically feasible and yields enhanced recovery with minimally invasive and cosmetic advantages without compromising the level of safety or cancer eradication.
