Abstract
BACKGROUND AND PURPOSE Central compartment lymph node metastasis (CLNM) is a manifestation of tumor aggressiveness and an indicator of tumor prognosis. The purpose of this study was to construct a nomogram for evaluating CLNM patterns in papillary thyroid carcinoma (PTC) in different age groups. METHOD A total of 907 patients diagnosed with PTC from August 2014 to December 2018 were enrolled. A nomogram illustrating CLNM was generated using the results of multivariate logistic regression analysis. RESULTS According to the best Youden index, we set the cut-off age at 45 years. Multivariate logistic regression analysis showed that in patients aged <45 years, large tumor size (P<0.05), extra-thyroid extension (P<0.05) and thyroglobulin level >40 ng/ml (OR=2.985, 95% CI 1.379-6.462; P<0.05) were independent risk factors; meanwhile, Hashimoto's thyroiditis (OR=0.532, 95% CI 0.324-0.874; P<0.05) was a protective factor of CLNM. In the subgroup with age ≥45 years, large tumor size (P<0.05), extra-thyroid extension (P<0.05), unclear margin (OR=1.604, 95% CI 1.065-2.416; P<0.05), male gender (OR=2.009, 95% CI 1.257-3.212; P<0.05) were independent risk factors for CLNM. In the subgroup with age <45 years, an area under the curve (AUC) of 0.729 (95% CI 0.680-0.777); P<0.05) was obtained. In the ≥45 years subgroup, the AUC was 0.668 (95% CI 0.619-0.716; P<0.05). CONCLUSION CLNM of PTC in different age groups may have distinct patterns. Based on the potential risk factors for CLNM in patients with different age stratification, a user-friendly predictive model was established.

Abstract
BACKGROUND Carbon nanoparticles (CNs) have been used intraoperatively in open thyroid surgery to facilitate central neck dissection and parathyroid protection. However, little attention was paid to the preoperative injection of CNs. Its safety and feasibility remain to be evaluated in bilateral axillo-breast approach robotic thyroidectomy (BABA RT). METHODS In this retrospective cohort study, 114 papillary thyroid cancer patients (PTC) undergoing BABA RT were enrolled from March 2020 to March 2021. In the CNs group (n=64), 0.15 mL of CNs was injected into the thyroid lobules with malignant nodules the day before surgery. Medical records were reviewed and analyzed, including complications of CNs usage, surgical outcomes, central lymph node (CLN) retrieval, and parathyroid glands (PGs)-related parameters. RESULTS No significant differences were found between the CNs and the control groups in terms of general characteristics and surgical parameters. Complications of CNs were rare in the CNs group. The mean number of retrieved CLN was significantly higher in the CNs group than in the control group (9.48±4.88 vs. 5.40±2.67, P<0.001), as was the mean number of metastatic CLN (2.00±2.56 vs. 1.04±1.70, P=0.018). There were no differences in PGs preserved in situ, PGs autotransplantation, and postoperative PTH levels on the first day and first month (all P>0.05). CONCLUSIONS In patients with PTC undergoing BABA RT, preoperative application of CNs is a safe and feasible method to facilitate central neck dissection. However, the value of the preoperative application of CNs in robotic thyroidectomy needs to be further studied because it has no significant benefit for parathyroid protection.

Abstract
BACKGROUND In recent decades, significant advances have been made in protecting the parathyroid glands and recurrent laryngeal nerves during thyro-idectomy. However, reliable and convenient technical means are still lacking. In this study, the reliability, safety and feasibility of near-infrared (NIR) laparoscopy-assisted 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.

Abstract
PURPOSE The purpose of the study was to investigate the predictive factors for hypoparathyroidism and its severity on the first postoperative day (POD1) after total thyroidectomy (TT) with or without central neck dissection (CND) in patients with papillary thyroid carcinoma (PTC). METHODS From February 2014 to February 2019, 2550 PTC patients were admitted to our department. PTC patients who underwent TT were enrolled in this study. A parathyroid hormone (PTH) level lower than 15 pg/mL on POD1 was defined as hypoparathyroidism, and the severity of hypoparathyroidism was classified into three categories according to the level of PTH on POD1: mild hypoparathyroidism (10 pg/mL ≤ PTH < 15 pg/mL), moderate hypoparathyroidism (5 g/mL ≤ PTH < 10 pg/mL), and severe hypoparathyroidism (PTH < 5 pg/mL). Multiple clinical, pathological and surgical parameters of these two different groups were compared and analyzed to demonstrate the possible causes of hypoparathyroidism. Furthermore, patients who developed postoperative hypoparathyroidism were also included in a subgroup analysis according to the severity of their hypoparathyroidism. The underlying factors affecting different severities of hypoparathyroidism were also illustrated with univariate and multivariate analyses. RESULTS Ultimately, 690 patients who underwent TT were enrolled in this retrospective study. Through the univariate analysis, different surgeons (P < 0.001), extent of CND (P = 0.009), prophylactic calcium supplementation (PCS) (P < 0.001), preoperative (pre-op) PTH level (P < 0.001), and pre-op phosphorus concentration (P = 0.022) were found to be significantly correlated with postoperative hypoparathyroidism. According to the multivariate analysis, PCS was the only independent high-risk factor for hypoparathyroidism. In the univariate analysis of patient subgroups with different severities of hypoparathyroidism, we demonstrated that the tumor T stage (P = 0.021) and pre-op PTH level (P < 0.001) were associated with the severity of hypoparathyroidism. Furthermore, after the multivariate analysis, hypertension (P < 0.001) and pre-op PTH (P < 0.001) were the two independent predictive factors for the severity of hypoparathyroidism after surgery. CONCLUSIONS Postoperative PCS could increase the risk for PTC patients developing hypoparathyroidism after thyroid surgery. Patients with a history of hypertension and a relatively high pre-op PTH level may not develop severe hypoparathyroidism after TT with CND.

Abstract
Introduction: Endoscopic thyroidectomy (ET) has been successfully established as an excellent surgical approach. This study summarizes and describes the crucial anatomical landmarks for clinical applied anatomy in trans-areolar ET, which may help further improve the quality and safety of trans-areolar ET. Materials and Methods: Five hundred forty patients who underwent trans-areolar ET from January 2015 to June 2018 at our institution were evaluated. Several crucial anatomical landmarks were described during the surgical procedures. The surgical outcomes, including the operative time, conversion, intraoperative blood loss, postoperative complications, and postoperative stay, were collected. Results: All patients successfully underwent trans-areolar ET without conversion. The mean operative time was 142.18 ± 49.91 minutes (150.84 ± 50.32 minutes for total thyroidectomy and 110.20 ± 32.4 for lobectomy with isthmusectomy). The mean intraoperative blood loss was 20.45 ± 10.89 mL. The postoperative stay was 5.42 ± 1.49 days. The postoperative complication rate was 7.78%, including transient hypocalcemia in 30 patients, transient recurrent laryngeal nerve palsy in 3 patients, and skin ecchymosis in 9 patients. Conclusions: An understanding of crucial anatomical landmarks for clinical applied anatomy may improve the quality and safety of trans-areolar ET and subsequently help promote the development of ET.

Abstract
BACKGROUND Injection of carbon nanoparticle (CN) into the thyroid gland is used to stain CLNs in endoscopic surgery of patients with papillary thyroid cancer (PTC). The black-dye technique facilitates the central lymph nodes (CLNs) harvest and parathyroid protection, but improper handling of CN during injection leads to unwanted staining of surrounding tissues and increases the difficulty in anatomical identification. Therefore, a new method is needed to overcome this problem. METHODS Forty-eight patients with PTC underwent endoscopic thyroidectomy via breast approach. Patients were randomized into the indocyanine green (ICG) group (Group ICG; n = 23) and CN group (Group CN; n = 25). After thyroid gland exposure, ICG was injected into the thyroid lobes. Fluorescent CLNs were identified and dissected in Group ICG. In Group CN, CN was used instead. Black dyed CLNs were harvested. The following was compared between groups: demographic characteristics, surgical time, drainage amount, hospital stay duration, number of CLNs harvested, frequency of postoperative hoarseness and hypothyroidism, and surgical cost. RESULTS Group ICG showed decreased hypoparathyroidism frequency than Group CN (1/23 vs. 7/25, p = 0.028) and more harvested CLNs (4.6 ± 1.0 vs. 3.8 ± 1.2, p = 0.020). There was no difference between drainage amount, hospital stay duration, and frequency of postoperative hoarseness. The cost of Group ICG was less than that of Group CN (p = 0). CONCLUSION Injection of ICG into the thyroid gland using fluorescence imaging in endoscopic surgery in patients with PTC is safer and more effective in identifying CLNs than injection with CN. This novel method can lead to improved identification and subsequent harvesting of CLNs.

Abstract
Background Some thyroid cancers are found after thyroidectomy for benign lesions, implying additional surgery and treatments. This work aimed to investigate the role of intraoperative sentinel lymph node biopsy (SLNB) for diagnosis of incidental thyroid carcinoma. Methods This was a retrospective study of 541 consecutive patients who underwent thyroid surgery between 02/2012 and 02/2014 at the Hunan Provincial People's Hospital. All patients were diagnosed with thyroid benign lesions preoperatively and intraoperatively. Among them, 375 underwent successful intraoperative SLNB using carbon nanoparticles (CNs). Results The preoperative diagnoses were nodular goiter (n=472), Hashimoto's disease with nodules (n=24), hyperthyroidism with nodules (n=16), and thyroid cysts with obstructive symptoms (n=29). In the SLNB group, SLN metastasis of thyroid microcarcinoma was confirmed in 21/392 cases (5.4%). These 21 patients received radical surgical treatment for thyroid carcinoma during the initial operation. In the no-SLNB group (n=149), seven patients (4.7%) were finally diagnosed with thyroid microcarcinoma. Six patients had to undergo a second surgery. Conclusions Intraoperative SLNB could help diagnose differentiated thyroid microcarcinoma that may be missed preoperatively and intraoperatively. This could prevent the need for a second surgery since the intraoperative frozen section examination of the SLNs can reveal metastasis from thyroid cancer.

Abstract
Background: The aim of this report was dual: (a) to describe the step-by-step standardized intraoperative percutaneous injection of carbon nanoparticles (CNPs) procedure for CNP-stained central compartment lymph nodes (CLNs) and passive display of parathyroid gland by CNP-stained thyroid in endoscopic thyroidectomy via bilateral areola approach (ETBAA) and (b) evaluation and outcomes of percutaneous injection of CNPs in total thyroidectomy plus CLN dissection through ETBAA. Materials and Methods: Video describes the technique of intraoperative percutaneous injection of CNPs for central compartment LNs identification, dissection, and parathyroid glands preservation in ETBAA for papillary thyroid cancer. Results: Supplementary video shows that after intrathyroid injection of CNPs, black carbon can be seen rapidly along the lymphatic vessels to the surrounding LNs. Parathyroid gland can be passive display when the thyroid is black and the parathyroid gland is normal in color. Intraoperative neuromonitoring (Medtronic® NIM-Response 3.0) was applied to identify recurrent laryngeal nerve and external branch of superior laryngeal nerve. No patient had any side effects of CNPs from 152 patients followed up for an average of 19.6 months (6-34 months). LNs were easily found under ETBAA. The accuracy of black-dyed LN in thyroid cancers was 95.9% (1016/1059). The number of parathyroid glands passive display was 69.9% (267/382). Conclusions: It is feasible to use CNPs to show CLNs in thyroid cancer during ETBAA. CNP suspension is safe for thyroidal injection.
