Abstract
BACKGROUND: Transoral robotic thyroidectomy (TORT) is an ideal method for minimally invasive thyroidectomy, as there is less flap dissection during the procedure and no postoperative scars. However, this method also has the limitation of present DaVinci system and some technical problems related to CO2 gas insufflation that must be resolved. We investigated the feasibility and safety of gasless TORT using the latest version of the DaVinci system (SP). METHODS: From October 2018 to January 2019, we performed 10 surgeries of gasless TORT using the DaVinci SP at Yonsei University Hospital. RESULTS: Nine patients underwent unilateral thyroid lobectomy and one patient received total thyroidectomy. All operations were successfully completed. Nine cases had papillary thyroid carcinoma, and one had benign nodules. The mean surgical time was 177 min, and the mean hospital stay was 6.3 days. There were no reports of transient or permanent vocal cord palsy, recurrence, or mortality during the follow-up period. Temporary hypoesthesia of the chin due to mental nerve injury was observed in 3 of 10 patients, but it recovered spontaneously within 1 months in all cases. CONCLUSIONS: Gasless TORT using the DaVinci SP system is feasible and safe for selected patients and is a potential alternative approach for scarless thyroid surgery.
