BACKGROUND In recent decades,significant advances have been made in protecting the parathyroid glands and recurrent laryngeal nerves during thyroidectomy.However,reliable and convenient technical means are still lacking.In this study,the reliability,safety and feasibility of near-infrared(NIR)laparoscopyassisted thyroid lobectomy with isthmectomy and prophylactic central lymph node dissection(CLND)were reported.CASE SUMMARY A 63-year-old female patient with a free previous medical history,was admitted to our department due to multiple thyroid nodules.Ultrasonic examination suggested diffuse thyroid changes and one thyroid nodule in the right upper lobe with the largest diameter of 1.5 cm adjacent to the trachea and Breast Imaging Reporting and Data System grade 4B.Imaging examination of the neck showed no obvious enlarged lymph nodes.Fine needle aspiration biopsy suggested a papillary thyroid carcinoma.Combined with thyroid function examination,the patient was diagnosed with papillary thyroid carcinoma and Hashimoto's thyroiditis.Considering the risk of invading the capsule and the patient's extreme anxiety,a right thyroid lobectomy with isthmectomy and prophylactic CLND was planned.No significant abnormalities were found during preoperative examinations,except for an increased thyroid stimulating hormone level.The patient underwent NIR laparoscopy-assisted thyroid lobectomy with isthmectomy and prophylactic CLND.During the operation,two right parathyroid glands(PGs)adjacent to the thyroid gland capsule and the right recurrent laryngeal nerve(RLN)were examined by indocyanine green(ICG)fluorescence using a NIR fluorescence camera,and the PGs and RLN were reliably preserved.Considering the ICG-positive PG,prophylactic CLND was performed.The postoperative parathyroid hormone level was in the normal range and no significant hypocalcemia symptoms were observed.CONCLUSION During NIR laparoscopy-assisted thyroidectomy,ICG fluorescence may aid PG identification and protection.
