Transoral endoscopic thyroidectomy vestibular approach for papillary thyroid microcarcinoma: an analysis of clinical outcomes.

objectiveTo analyze the influence of transoral endoscopic thyroidectomy vestibular approach (TOETVA) on the clinical outcomes of patients with papillary thyroid microcarcinoma (PTMC).

methodsThe clinical data of PTMC patients (n=90) who visited the Affiliated Changzhou No. 2 People's Hospital of Nanjing Medical University from July 2019 to July 2021 were retrospectively analyzed. Patients who underwent endoscopic thyroidectomy via the transthoracic-areola approach were included in the control group (CG; n=42) and those with TOETVA were assigned to the observation group (OG; n=48). The operative time (OT), length of hospital stay (LOS), postoperative drainage volume, and complications were recorded. Besides, C-reactive protein (CRP), white blood cell count (WBC), erythrocyte sedimentation rate (ESR), as well as scores of the Visual Analogue Scale (VAS), Vancouver Scar Scale (VSS), postoperative patient satisfaction, and the Short-Form 36 Item Health Survey (SF-36) were compared between the two groups.

resultsThe data showed that the OT and LOS of the OG were not statistically different from those of the CG, and the postoperative drainage volume was less than that of the CG (P<0.05). The two cohorts of patients showed a similar incidence of complications such as postoperative hematoma, transient hoarseness, infection, temporary recurrent laryngeal nerve injury and transient hypothyroidism (all P>0.05). CRP, WBC and ESR increased in both groups after treatment but showing no evident difference between groups. The OG had statistically lower VAS and VSS scores at two days after surgery, a statistical higher satisfaction rate than the CG, and a statistically higher score of SF-36 at three months after surgery than in the CG (all P<0.05).

conclusionsWhile ensuring the therapeutic effect, TOETVA can significantly reduce the pain degree of patients and scarring, as well as provide better cosmetic effect, higher patient satisfaction, and better quality of life, which is worthy of clinical promotion.
