Challenging routine: technical difficulties and solutions of endoscopic thyroidectomy via a combined transoral and...

Conventional cervical lymph node dissection often leaves large surgical scars, which seriously compromises the postoperative aesthetic effect and can affect the quality of life of patients. In this study, the safety and feasibility of robotic-assisted endoscopic thyroidectomy with central neck dissection (CND) and lateral neck dissection (LND) via a combined transoral and breast approach are discussed in detail.

A retrospective analysis was made of the data of 26 patients with stage cN1b papillary thyroid carcinoma who were admitted to the Thyroid Surgery Department of the Hunan Cancer Hospital from March 2021 to September 2022 and who underwent robotic-assisted endoscopic thyroidectomy with LND via a combined transoral and breast approach. The demographic data, surgical indicators, postoperative data, and the postoperative complication rate of the patients were analyzed, and the learning curve was analyzed by cumulative summation.

All the patients underwent endoscopic surgery without any conversion to open surgery. The mean operation time was 313.7±50.3 min and the mean number of total positive/retrieved lymph nodes was 11.2±8.1/36.8±13.7. Two patients developed temporary laryngeal recurrent nerve palsy and three patients developed temporary hypoparathyroidism, all of whom recovered within 3 months postoperatively. No tumor recurrence occurred during follow-ups that ranged from 6 to 24 months. The mean postoperative quality of life (QOL) score was 189.1±118.2, test results ranging from 0 to 1300 with a lower score indicating a higher QOL, and the aesthetic satisfaction score was 4.2±0.7, test scores ranging from 0 to 5 with higher scores indicate higher satisfaction. The turning point of the learning curve was in the 11th case.

The robotic-assisted endoscopic thyroidectomy with CND and LND via a combined transoral and breast approach is safe and feasible, and the improved cosmetic effect is remarkable, which is conducive to improving the postoperative QOL of patients. It provides a new surgical option for patients.
