Re-do transoral robotic thyroidectomy is feasible: preliminary results of the surgical feasibility and efficacy of completion transoral robotic thyroidectomy: cohort study.

ABSTRACT

BACKGROUND: Transoral robotic thyroidectomy (TORT) has proven to be a safe and effective procedure with favourable surgical and cosmetic outcomes, but its application in completion thyroidectomy procedures remains to be established. In this study, the authors present our experience with completion TORT, assessing its surgical feasibility and efficacy. between February 2017 and August 2023. METHODS: The authors conducted a retrospective analysis of consecutive patients who underwent completion TORT after an initial TORT procedure between February 2017 and August 2023. RESULTS: A total of 10 patients (three males and seven females) were included in the study, with a mean age of 42.2±13.5 years. The indications for completion thyroidectomy included five cases of aggressive initial lesions and five cases of metachronous papillary thyroid carcinoma detected in the remnant lobe. The median interval between the initial and completion TORT procedures was 6.5 months. Flap dissection time showed no significant difference between the initial TORT and completion TORT operations (43.3±7.5 vs. 36.2±11.2, P =0.125). However, the mean console time (127.9±42.6 vs. 86.4±26.3 min, P =0.019) and mean total operation time (206.7±65.9 vs. 146.0±34.9 min, P =0.021) were significantly longer during the initial TORT procedure than during the completion TORT procedure. Two patients experienced transient hypoparathyroidism, which resolved within four weeks postoperatively. No other complications, such as vocal cord palsy, mental nerve injury, or bleeding, were observed. The median follow-up period was 21.5 months, and no recurrences were detected in any of the patients. CONCLUSIONS: Our study demonstrates that re-do TORT is feasible, showing excellent cosmetic results and minimal adverse effects. Completion TORT may be considered a viable option for selected patients who require completion thyroidectomy after an initial TORT procedure.
