Research progress of complications related to robotic thyroid surgery-comparison of TORT and BABA approaches / 中华内分泌外科杂志

In recent years, clinical applications of robotic thyroid surgery have been gradually promoted with the continuous improvement of the da Vinci robotic surgical system. Unlike traditional open surgery, robotic thyroid surgery mainly adopts remote access, which has many advantages, such as magnified high-definition 3D view and hand vibration stabilization. The rates and causes of postoperative complications differ due to different approaches, view angles, and operation sequences. This paper presents the literature on both transoral and bilateral areolar axillary approaches in robotic thyroid surgery, focusing on five common complications under both approaches, including laryngeal recurrent nerve injury and hypoparathyroidism, to provide theoretical support for the standardization of robotic thyroid surgery.

Clinical application of parathyroid autofluorescence imaging in endoscopic thyroid surgery / 临床耳鼻咽喉头颈外科杂志

Objective:To investigate the application value of near-infrared autofluorescence imaging in identifying and protecting parathyroid glands in endoscopic thyroid surgery. Methods:From May 2022 to February 2023, 158 patients who underwent endoscopic thyroid surgery in the Department of Thyroid and Breast Vascular Surgery of Guilin People's Hospital were selected. The endoscopic fluorescence camera system was used to monitor the parathyroid glands under autofluorescence during endoscopic thyroid surgery. A total of 214 pieces were collected, among which the first 15 cases that could not be preserved in situ during the operation needed to be autotransplanted or the tissue clamped parts that could not be clearly identified as parathyroid glands were sent to fast-frozen pathology to determine whether they were parathyroid glands. Results:Among the first 15 patients who could not be preserved in situ during the operation or whose anatomy could not be clearly defined, 23 parathyroid glands were detected by autofluorescence imaging, 21 parathyroid glands were confirmed by pathology, and 2 were adipose tissue, with an accuracy rate of 91.30%; 158 patients underwent surgery Blood calcium decreased 2 hours after operation compared with preoperative blood calcium（P<0.05）, decreased blood calcium 5 days after operation compared with preoperative blood calcium（P<0.01）, and increased slightly 5 days after the operation compared to blood calcium 2 hours after the operation, but the difference was not statistically significant（P>0.05）; while comparing parathyroid hormone（PTH）, PTH at 2 hours after operation decreased significantly compared with PTH before operation（P<0.01）, and PTH at 5 days after operation compared with PTH before operation PTH also decreased（P<0.01）, but increased compared with PTH 2 hours after operation（P=0.001）. Conclusion:In laparoscopic thyroid surgery, the application of near-infrared autofluorescence imaging technology can help surgeons quickly identify and protect parathyroid glands, and reduce the incidence of permanent hypoparathyroidism. Combining autofluorescence imaging, visual anatomy recognition under magnification of laparoscope, and intraoperative frozen pathological examination "trinity" method can improve the success rate of parathyroid gland recognition.

The influence of loss of intraoperative nerve monitoring signal on decision-making of total thyroidectomy: similarities and differences between Chinese and western perspectives / 中华内分泌外科杂志

With the popularization of intraoperative nerve monitoring (IONM) , it is possible to determine the intraoperative nerve function, which provides evidence-based basis for surgical decision making. Intraoperative loss of nerve signal (LOS) often indicates postoperative vocal cord dyskinesia. Once LOS occurs intraoperatively, the next surgical strategy adopted by the operator has always been controversial among Chinese and western experts. Therefore, this paper makes a comparative analysis of the differences between the viewpoints of domestic experts and western scholars and the possible causes through the investigation of domestic and foreign literature to provide theoretical basis for better thyroid surgery decision.

Thyroid disorders, epidemiology and outcome among patients in South Western region: Southern Saudi Arabia

Background: Thyroid gland may have a group of a medical condition that affects its main function. The thyroid gland is located at the front of the neck and produces thyroid hormones. The released hormones go through the blood to many body organs for regulating their function, meaning that it is an endocrine organ. These hormones normally act in the body to regulate energy use, infant development, and childhood development. The study aimed to assess the epidemiology of thyroid disorders among cases in the south-western region, Saudi Arabia, and to assess the reporting quality for these cases data.Methods: A retrospective record based descriptive approach was used through reviewing medical records of all cases that were admitted and diagnosed as thyroid related disorders for different indications in the main hospital (king Khalid Hospital) during the period from January 2018 to January 2020. Data extracted throng pre-structured questionnaire including patient's bio-clinical data, preoperative radiological and laboratory investigations. Also, laryngoscope pre and post operatively was reviewed to record findings.Results: The study included 405 cases with thyroid disorders whose ages ranged from 15 to 71 years old with a mean age of 30.5±10.6 years. Females were 82.7% of the included cases, and 83.8% were Saudi. Thyroid related symptoms were recorded for 1-2 years among 58.1% of the cases and for more than 5 years among 15.8%. Thyroid enlargement was recorded for 73.1% of the cases. The multinodular enlargement was recorded for 53.5% of the cases followed with diffuse thyroid enlargement (27.3%). Regarding the type of surgery undergone, total thyroidectomy was the most recorded followed with lobectomy.Conclusions: The study revealed that the majority of the cases were females at middle age presented with benign lesions with Euthyroid status. The most important conclusion was the significant remarkable underreporting of the different clinical data for the cases with many missing items.

Aumento de la capacidad diagnóstica de la ecografía (informada con clasificación t-rads) cuando se agrega una punción aspirativa con aguja fina (informada con sistema bethesda) / Increase of the diagnostic yield of thyroid sonogram (reported with t-rads clasification) when a fine needle aspiration cytology (reported with bethesda system) is added

Cuando un nódulo tiroideo muestra características ecográficas sospechosas de malignidad (informada con clasificación T-RADS) casi no se discute que debe completarse el diagnóstico con una punción aspirativa con aguja fina (PAAF) (informada con sistema Bethesda). Pero cuando la ecografía sólo muestra características consideradas de benignidad, la indicación de PAAF es cuestionable y debe ser justificada. ¿Podrá la clasificación T-RADS determinar eficientemente cuáles nódulos tiroideos requieren una PAAF y cuáles no? Esta decisión está vinculada a determinar si un paciente deberá ser sometido o no a una cirugía tiroidea. Objetivo: Analizar la capacidad de la clasificación T-RADS, con y sin el agregado de sistema Bethesda para optimizar el diagnóstico de patología tiroidea. Material y métodos: se incluyeron 139 nódulos que requirieron cirugía, previamente evaluados con ecografía y con PAAF. Fueron realizadas por un mismo operador las ecografías (SMB), las punciones (OBM) y las cirugías (JLN). Se homogeneizaron las definiciones: T-RADS II-III-IVa y Bethesda II-III: Baja sospecha de malignidad; T-RADS IVb-V-VI y Bethesda IV-V-VI: Alta sospecha de malignidad. Conslusiones: se comprobó que cuando las características ecográficas de un nódulo tienen baja sospecha de malignidad (T-RADS II-III-IVa), indicar una PAAF no aporta al diagnóstico en forma estadísticamente significativa. Cuando la ecografía indica alta sospecha de malignidad (T-RADS IVb-V-VI), la realización de una PAAF incrementa significativamente la certidumbre del diagnóstico (AU)

When a thyroid nodule shows ultrasonographic characteristics of malignancy suspicion (informed with T-RADS classification), almost nobody discusses to complete diagnosis with a fine needle aspiration biopsy (FNAB) (informed with Bethesda system). But when ultrasonography only shows characteristics compatible with benignity, a FNAB indication is questionable and that must be justified. Could T-RADS classification efficiently identify which nodule requires a FNAB and which does not? That decision will linked to which patients should be undergo a thyroid surgery. Objective: to analyze T-RADS capability with and without Bethesda system to optimize the diagnosis of thyroid pathology. Material and methods: a total of 139 nodules which required surgery were included. They were previously evaluated with ultrasonography and FNAB. A same operator classified the T-RADS (SMB), the Bethesda system (OMB) and performed the surgeries (JLN). For this work, definitions were homogenized as follows: T-RADS II-III-IVa and Bethesda II-III: Low suspicion of malignancy; T-RADS IVb-V-VI and Bethesda IV-V-VI: High suspicion of malignancy. Conclusions: the evidence suggested that when a thyroid nodule shows low suspicion of malignancy by ultrasonography (T-RADS II-III-IVa), the indication of a FNAB did not add statistically significant diagnostic benefit. When a thyroid nodule shows high suspicion of malignancy (T-RADS IVb-V-VI), a FNAB added significant diagnostic accuracy (AU)

Bilateral absence of inferior thyroid artery: A rare variation

Background: There are reports regarding the origin of the inferior thyroid artery from the vertebral artery and internal thoracic artery. The absence of inferior thyroid artery has been reported in studies, but most of these studies have reported the unilateral absence of inferior thyroid artery. Objective: The objective of the study was to identify and variations in origin (especially presence or absence of artery) and branches of inferior thyroid artery. Materials and Methods: A total of 96 cadavers were dissected and observed for origin and branching pattern of inferior thyroid artery. Results: Inferior thyroid artery originated from thyrocervical trunk in 94 cadavers, in one cadaver there are bilateral absence of inferior thyroid artery and in one case unilateral absence of Rt. inferior thyroid artery. Multiple variations of relations of recurrent laryngeal nerve and inferior thyroid artery are found. Conclusion: Knowledge of arterial variation is extremely important while carrying out surgical procedures in the neck region. During operations of the thyroid gland, surgeries of neck region, carotid angiographies any misinterpretation can lead to life-threatening complications. This study is not only focusing on the presence of different branching pattern but also the absence of major arteries. Studies like these can help surgeons to look closely for variations in both cases either presence or absence of main arteries.

Landmark for Identification and Location of Parathyroid Glands during Thyroidsurgeries

Parathyroid glands always remain at risk of damage during the thyroid surgery as they lie in close proximity to the thyroid gland. Parathyroid glands are small endocrine glands that produce parathyroid hormone. The major function of parathyroid hormone is to maintain the level of calcium and phosphate within a narrow range in the body. Aim of the present study was to locate and identify the parathyroid glands during thyroid surgery and to observe their relationship with the surgical landmarks. The present study was a prospective study conducted in the department of otorhinolaryngology and HNS in SMGSH, GMC, Jammu for a time period of 1 year from Nov.2015 to Oct. 2016. 40 patients undergoing thyroid surgery were included in the study. Meticulous technique was employed during dissection and parathyroid glands were identified in the surgical field. Location of the each parathyroid gland was determined in relation to a nearby surgical landmark. The study included 12 right (R) and 8 left (L) hemithyroidectomies, 10 sub- total thyroidectomies and 1 total thyroidectomy. An average of 1.2 parathyroid glands were identified in hemithyroidectomies and 2.4 was the average number of parathyroid glands identified in subtotal and total thyroidectomies. Location of parathyroid glands was observed in relation to cricothyroid (CT) joint, recurrent laryngeal nerve (RLN), inferior thyroid artery (ITA) and tubercle of Zukerkandl for superior parathyroid glands, and in relation to RLN, RLN & ITA junction, tubercle of Zukerdandl & lower pole for inferior parathyroid glands. In this study RLN was the most frequent landmark for identification of superior parathyroid gland while the inferior parathyroid glands were frequently seen related to the lower pole of the thyroid gland.

Variation in the Origin of Superior Thyroid Artery and it’s Relation with External Laryngeal Nerve: A Cadaveric Study

Introduction: The Thyroid gland is a highly vascular gland placed anteriorly in the neck, extending from the level of fifth cervical vertebra to first thoracic vertebra.The lobes of gland are conical. Their apices diverge laterally to the oblique line on the lamina of thyroid cartilage, and their bases are at the level of 4th or 5th tracheal ring. The relationship of the superior thyroid artery to the external laryngeal nerve is important to the surgeon during thyroid surgery.The artery and nerve are close to each other higher up but diverge near the gland. Thus in order to avoid injury to the external laryngeal nerve, the superior thyroid artery is ligated as near to the gland as possible. Subjects and Methods: This study was conducted on 50 cadavers of known age and sex in the dissection laboratory, department of anatomy. The cadavers were embalmed through carotid arterial perfusion or femoral arterial perfusion. Results: The site of the origin of the superior thyroid artery (STA) was evaluated as it arose from external carotid artery in 66% cases, from carotid bifurcation in 33% cases and from common carotid artery in 1% cases.The site of the origin of the superior thyroid artery (STA) was evaluated as it arose from external carotid artery in 66% cases, from carotid bifurcation in 33% cases and from common carotid artery in 1% cases.The evaluation of distance from upper pole of the thyroid gland to the level where External superior laryngeal nerve turns medially from Superior thyroid artery was found More than 1 cm in 73% cases & Less than 1 cm in 27% cases. Conclusion: The relationship of superior thyroid artery to external superior laryngeal nerve is very important for surgeons during thyroid surgeries to avoid injuries to above nerves while ligating STA.

Material y métodos: revisión retrospectiva de las historias clínicas de 773 pacientes operados por patología tiroidea entre enero de 2014 y diciembre de 2015. En todos se efectuó EPI y EPD; a 686 (89%) pacientes también se les efectuó la biopsia por PAAF preoperatoria. Resultados: los resultados del EPI fueron benigno en 215 pacientes (27,8%), maligno en 419 (54,2%) y no definitivo en 139 (18,0%). Cuando estos resultados fueron comparados con la EPD se encontraron 19 casos (8,8%) de falsos negativos y 4 (0,95%) de falsos positivos. Considerando solo los resultados definitivos, el EPI tuvo sensibilidad 95%, especificidad 98%, valor predictivo positivo 99%, valor predictivo negativo 91% y exactitud 91%. Cuando se comparó el EPI con la PAAF preoperatoria, los valores de sensibilidad más bajos (44%) correspondieron a las categorías de Bethesda III y IV. El EPI influyó en la estrategia quirúrgica en 95 pacientes (12,28%): en 53 (6,8%), la hemitiroidectomía cambió a tiroidectomía total; en 37 (4,8%), el diagnóstico de metástasis ganglionares permitió realizar un vaciamiento modificado de cuello, y en 5 (0,6%) ocurrieron ambas situaciones. Conclusión: el EPI tuvo altos valores de utilidad diagnóstica cuando se compararon con el EPD. También se correlacionó con la PAAF preoperatoria, pero tuvo menos utilidad en las categorías Bethesda III y IV. El EPI contribuyó a cambiar la decisión de técnica quirúrgica en un grupo de pacientes y evitar una segunda operación.

Background: the role of intraoperative pathologic evaluation (IPE) in thyroid surgery has largely been discussed and it is still controversial. Objective: to estimate the results of IPE in diagnosis of malignancy, its correlation with preoperative fine needle aspiration (FNA) biopsy and permanent pathologic evaluation (PPE), and its contribution to change surgical strategy in thyroid surgery. Materials and methods: retrospective chart review of 773 patients operated on for thyroid disease between January 2014 and December 2015. All patients underwent IPE and PPE; 686 (89%) patients had also preoperative FNA biopsy. Results: IPE resulted benign in 215 patients (27.8%), malignant in 419 (54.2%) and non definitive in 139 (18.0%). When these results were compared with PPE, 19 cases were false negative (8.8%) and 4 false positive (0.95). Considering only definitive results, IPE had sensitivity 95%, specificity 98%, positive predictive value 99%, negative predictive value 91% and accuracy 91%. When IPE was compared with preoperative FNA biopsy, lowest values of sensitivity (44%) corresponded with Bethesda categories III and IV. IPE influenced surgical strategy in 95 patients (12.28%): in 53 (6.8%) hemithyroidectomy changed to total thyroidectomy, in 37 (4.8%) lymph node metastases diagnosis allowed to perform modified neck dissection, and in 5 (0.6%) both situations occurred. Conclusion: IPE had high values of diagnostic utility when compared with PPE. It also correlated with preoperative FNA biopsy, but had less utility in Bethesda categories III and IV. IPE contributed to change surgical technical decision in a subset of patients and avoid a second operation.
