Objective To systematically evaluate the reliability and stability of transoral endoscopic thyroidectomy vestibular approach (TOETVA) and conventional open thyroidectomy (COT) in the treatment of differentiated thyroid cancer.Methods The clinical studies of TOETVA and COT in the treatment of differentiated thyroid cancer were retrieved from major databases including PubMed, Embase, Cochrane Library, Wanfang, and CNKI by computer. The search date ended on March 1, 2020. Two investigators screened the literatures strictly and extracted the data following the pre-defined inclusion and exclusion criteria, and then used RevMan 5.3 software for meta-analysis.Results A total of 7 studies including 1 465 patients were included in this meta-analysis. The results showed: compared with the COT group, the operation time of the TOETVA group was longer [WMD=35.18, P=0.000 1], and the number of lymph node dissections in the central area was larger [WMD=1.42, P=0.000 5]. But the intraoperative blood loss [WMD=–5.32, P=0.39], the length of hospital stay after operation [WMD=0.05, P=0.94], the incidences of transient recurrent laryngeal nerve palsy [OR=0.81, P=0.43], transient hypocalcemia [OR=0.55, P=0.35], permanent hypocalcemia [OR=0.39, P=0.22], permanent recurrent laryngeal nerve palsy [OR=1.34, P=0.73], and hematoma [OR=1.29, P=0.69] were not statistically significant between the two groups.Conclusions TOETVA has a higher stability. Although the COT has a shorter operation time, the former has a higher central lymph node dissection rate, and there is no scar on the neck after surgery and no significant difference in the incidence of postoperative complications.
