Abstract
BACKGROUND: We aimed to evaluate the feasibility and oncologic safety of gasless endoscopic transaxillary thyroidectomy (TAT) in patients with thyroid diseases. Improvements in surgical techniques were also reported, and the learning curves of gasless endoscopic TAT were further studied. METHODS: An exact 1:1 matching analysis was performed to compare the technical safety and oncologic outcomes between TAT and conventional open surgery. A questionnaire was designed to evaluate the quality of life of enrolled patients. A cumulative summation analysis was designed for the quantitative estimation of the learning curves. RESULTS: A total of 105 consecutive patients who successfully received endoscopic TAT were retrospectively enrolled in the current study. A standard three-step working space making procedure, an approach that does not free the superficial part of the sternal head of the sternocleidomastoid muscle (SCM, NFSSH) and a "point to line to surface" en bloc procedure utilized in lobectomy with ipsilateral central neck dissection (CND), were introduced in our surgical procedures. The mean operation time in the TAT group was significantly longer than that in the conventional open group (86.9 ± 31.3 vs 44.2 ± 8.3, p < 0.001). Significant differences in the complication rate were not found between the two groups. Discomfort in the anterior neck area and SCM was relieved over time in most cases (verbal response scores (VRSs) were gradually decreased over time). The learning curves for working space making, ipsilateral thyroidectomy and the total endoscopic TAT approach were 45 cases, 25 cases and 42 cases, respectively. The operation time in the proficient group was significantly shorter than that in the learning group (67.0 ± 8.4 vs 112.3 ± 35.7, p < 0.001). VRSs in the SCM were significantly lower in the proficient group (for 1 week: 1.25 ± 0.65 vs 2.40 ± 0.63, p < 0.001; for 1 month: 0.81 ± 0.69 vs 1.81 ± 0.40, p < 0.001). CONCLUSIONS: Gasless endoscopic TAT was safe in a cohort of patients with thyroid diseases, with satisfactory surgical outcomes and cosmetic appearance. The learning curve for endoscopic TAT was approximately 42 cases. The proficiency of the endoscopic TAT approach depended primarily on the proficiency of working space making.
