Thyroidectomy In Patients Research Articles

The Impact of Thyroidectomy and Lobectomy on Patients' Health-Related Quality of Life, Eastern Region, Saudi Arabia.

The thyroid gland is a crucial endocrine organ that can be susceptible to various pathological conditions, often necessitating total thyroidectomy or lobectomy. It is a common surgical procedure in Saudi Arabia. Thus, it is essential to recognize the impact of thyroid surgery on patients' health-related quality of life (HRQoL). The aim of this study was to evaluate HRQoL among patients with benign and malignant thyroid diseases who underwent thyroidectomy in the eastern region of Saudi Arabia. This cross-sectional study was conducted at King Fahad Hospital of University in Khobar, Kingdom of Saudi Arabia from January 2018 to May 2018. The data collection method used was divided into two parts. Part I included the patients' socio-demographic characteristics and the clinical characteristics of their thyroid surgery. Part II was a HRQoL questionnaire (SF-36, version 1.0). The sample included 100 thyroidectomy patients ≥18 years. The study findings revealed that the overall scores for post-thyroidectomy patients showed a significant improvement in HRQoL, and HRQoL was not significantly associated with benign or malignant thyroid diseases. Especially when the surgery is performed by a high-volume endocrine surgeon, thyroidectomy may lead to significant improvements in HRQoL among patients, including the elderly and younger adults, with benign and malignant thyroid disorders. There was no difference in HRQoL between patients who underwent total thyroidectomy or thyroid lobectomy. Also, HRQol among thyroidectomy patients is associated with their educational and occupational statuses.

The role of intraoperative central lymph node biopsy in the treatment of clinically low-risk PTMC.

To evaluate the role of intraoperative frozen biopsy of central lymph nodes in central neck dissection and thyroidectomy in patients of unilateral, clinically negative nodes (cN0) papillary thyroid microcarcinoma (PTMC) without extra-glandular invasion. The clinical data of 465 patients were collected retrospectively. Part of prelaryngeal, pretracheal and ipsilateral paratracheal lymph nodes were taken for frozen pathological examination during the operation. Then the thyroid lobe on the tumor side and isthmus were excised, and central neck dissection of the affected side was performed in all patients. The number of metastases in entire central lymph nodes of the affected side can be obtained by postoperative paraffin pathology. If the number of positive lymph nodes during surgery is ≥3, contralateral gland resection was performed. In this group of 465 patients, there were 186 cases with central lymph node metastasis. The Kappa coefficient of consistency between frozen pathology and paraffin pathology in central lymph nodes was 0.605. The ROC curve for the number of intraoperative frozen metastases-postoperative pathological metastases over 5 showed that the AUC of the curve was 0.793, while the maximum Youden index was 0.5259, whose corresponding number of positive lymph nodes was 3. Intraoperative central lymph nodes biopsy can be used as an important indicator for the status of central lymph node metastasis in unilateral cN0 PTMC patients without extra-glandular invasion and a determinant for central lymph node dissection. While the number of positive lymph nodes intraoperatively is ≥3, total thyroidectomy should be considered.

Comparison of gasless transaxillary endoscopic thyroidectomy, endoscopic thyroidectomy via areola approach and conventional open thyroidectomy in patients with unilateral papillary thyroid carcinoma

BackgroundGasless transaxillary endoscopic thyroidectomy (GTET) and endoscopic thyroidectomy via the areola approach (ETA) have emerged as minimally invasive surgical techniques for managing papillary thyroid carcinoma (PTC). This study aimed to assess the surgical efficacy of endoscopic thyroidectomy (ET) as compared to conventional open thyroidectomy (COT) in PTC patients.MethodsBetween 2020 and 2022, 571 PTC patients underwent unilateral thyroidectomy accompanied by ipsilateral central lymph node dissection. This cohort comprised 72 patients who underwent GTET, 105 ETA, and 394 COT. The analysis encompassed a comprehensive examination of patient clinicopathologic characteristics and postoperative complaints. Furthermore, the learning curve of GTET was evaluated using the cumulative summation (CUSUM) method.ResultsPatients in the ET group exhibited a lower mean age and a higher proportion of female individuals. Operation time in the ET group was significantly longer. No significant differences were observed in the incidence of postoperative complications among the three groups. With regard to postoperative complaints reported three months after surgery, GTET demonstrated superior alleviation of anterior chest discomfort and swallowing difficulties. Patients who underwent ET reported significantly higher cosmetic satisfaction levels. Additionally, the learning curve of GTET was 27 cases, and the operation time during the mature phase of the learning curve exhibited a significant reduction when compared to ETA.ConclusionsThe findings of this study affirm the safety and feasibility of employing GTET and ETA for the surgical management of PTC. GTET presents an attractive surgical option, particularly for patients with unilateral PTC who place a premium on cosmetic outcomes.

Alterations in Body Weight and Composition in Patients With Graves' Disease Treated with Total Thyroidectomy.

Thyrotoxicosis causes excess energy expenditure, resulting in weight loss, despite increased appetite, and changes in body composition, which are typically reversible with the normalization of thyroid hormone levels. However, patients with hyperthyroidism due to Graves' disease are sometimes hesitant to undergo treatment because of the perceived morbidity associated with weight gain. Therefore, obtaining data to explain the details of such weight gain to these patients is important. This study aimed to investigate changes in body weight and composition in patients with Graves' disease after total thyroidectomy. In total, 21 patients with Graves' disease who underwent total thyroidectomy were enrolled. Among them, nine patients were hyperthyroid (group A) and 12 were euthyroid (group B, control) immediately before surgery. Body weight, height, and body composition using bioelectrical impedance were measured preoperatively and five months postoperatively. In all patients, body weight, body mass index, and skeletal muscle mass, but not fat mass, significantly increased postoperatively. In individual groups, a significant increase in skeletal muscle and fat masses was observed solely in groups A and B, respectively. Furthermore, a significant positive correlation between preoperative thyroid function and differences in skeletal muscle mass preoperatively and postoperatively was found. Our study shows that the normalization of thyroid function using thyroidectomy in patients with Graves' disease is accompanied by weight gain, mainly due to an increase in skeletal muscle mass. These data are clinically significant because they enable physicians to explain to patients that weight gain after surgical treatment for Graves' disease is favorable and reassure them of their concern.

반회후두신경을 침범한 갑상선 유두암 환자에서 수술 중 신경감시의 적용

Intraoperative neuromonitoring (IONM) has been widely applied for thyroidectomy in patients with papillary thyroid carcinoma (PTC) to identify and preserve the recurrent laryngeal nerve (RLN). Moreover, IONM may be helpful to predict the postoperative function of the vocal fold and provide rationales to decide the extent of surgery, including staged operation. However, the usefulness of IONM in patients with PTC involving the RLN has not been well introduced. Invasion of the PTC to the RLN may have lesser impact on survival of the patient compared to that to the trachea or esophagus. Therefore, preservation or resection of a functioning nerve involved by cancer may be a controversial issue. In this article, usefulness of IONM in patients with PTC involving the RLN will be reviewed based on recent related studies and guidelines.

Surgical outcomes of robotic thyroidectomy for thyroid tumors over 4 cm via the bilateral axillo-breast approach

The study investigated the feasibility of robotic bilateral axillo-breast approach (BABA) thyroidectomy for patients with thyroid tumors larger than 4 cm. BABA thyroidectomy has previously shown safety and effectiveness for thyroid surgeries but lacked extensive data on its application to larger tumors. Between October 2008 and August 2022, there were 74 patients underwent robotic BABA thyroidectomy due to thyroid nodules exceeding 4 cm in size. The mean patient age was 40.3 years. Fine needle aspiration results classified the tumors as benign (50.0%), atypia of undetermined significance (27.0%), follicular neoplasm (16.2%), suspicious for malignancy/malignancy (5.4%), or lymphoma (1.4%). The average tumor size was 4.9 cm, with the majority (85.1%) undergoing thyroid lobectomy, and the rest (14.9%) receiving total thyroidectomy. The mean total operation time was 178.4 min for lobectomy and 207.3 min for total thyroidectomy. Transient vocal cord palsy (VCP) was found in 3 patients (4.1%), and there was no permanent VCP. Among patients who underwent total thyroidectomy, transient hypoparathyroidism was observed in three (27.2%), and permanent hypoparathyroidism was observed in one (9.1%). There were no cases of open conversion, tumor spillage, bleeding, flap injury, or tumor recurrence. In conclusion, robotic BABA thyroidectomy may be a safe treatment option for large-sized thyroid tumors that carries no significant increase in complication rates.

Long-Term Changes of Urinary Exosomal Peptide Levels After Thyroidectomy in Patients with Thyroid Cancer: A Prospective Observational Study.

The recurrence rate of thyroid cancer can be as high as 30%. The purpose of this study was to examine changes of urine exosomal peptide levels after thyroidectomy in patients with thyroid cancer to determine if levels can predict the risk of recurrence. Patients >20 years old as newly diagnosed with papillary thyroid cancer who had received a thyroidectomy were recruited. Urine samples were collected at 12 months after enrollment to the study, and 1 year later. Urine exosomes containing different peptides were identified and compared. A total of 70 patients were enrolled in the study, and were classified by the interval between surgery and enrollment: 42 patients with < 5 years between surgery and enrollment, 14 patients between 5-10 years, and 14 patients longer than 10 years. No recurrence was observed in any patient during the 2 years after enrollment. No significant differences were found in the levels of serum proteins or urine exosomal peptides between groups, or between intervals. Known risk factors for high-risk thyroid cancer had only a mild correlation with serum protein levels and urine exosomal peptides. Our study revealed the long-term basal fluctuation ranges of serum proteins and urine exosomal peptides in patients with thyroid cancer who underwent thyroidectomy. For high-risk patients after thyroidectomy, concentrations of serum proteins or urine exosomal peptides within the ranges may indicate there is a lower risk of thyroid cancer recurrence during long-term follow-up.

Outcomes of Immediate Total Thyroidectomy in First-Side Loss of Neuromonitoring Signal

Use of intraoperative neuromonitoring (IONM) during thyroidectomy can nearly eliminate the risk of postoperative bilateral vocal cord palsy (VCP) by indicating staged surgery in cases of loss of signal (LOS) on the first side of planned total thyroidectomy. However, aborting planned total thyroidectomy may lead to persistence of symptoms, delay in adjuvant treatment, and patient inconvenience and distress. There are few data to guide a selective approach to total thyroidectomy in patients with first-side LOS. To investigate outcomes of immediate bilateral surgery in patients undergoing total thyroidectomy with first-side LOS. This cohort study was a retrospective review of outcomes for patients undergoing thyroidectomy between January 2016 and July 2023 at an academic tertiary referral center for thyroid surgery. Consecutive patients scheduled for total thyroidectomy using IONM were included. Exclusion criteria were preoperative VCP, deliberate sacrifice of recurrent laryngeal nerve (RLN), inadvertent RLN resection, and surgery performed without IONM. Total thyroidectomy performed using IONM. Vocal mobility on first postoperative day as assessed by flexible laryngoscopy; secondary outcome measures included subjective voice assessment, other postoperative complications, and long-term vocal mobility. Among 400 patients undergoing planned total thyroidectomy (mean age, 50.5 years [range, 4-88 years]; 318 female [79.5%]), 51 (12.8%) had first-side LOS, of whom 37 (9.3%) had persistent LOS. Twenty-nine patients (56% of procedures with first-side LOS, including 18 with persistent LOS) proceeded to immediate total thyroidectomy. Postoperatively, 16 patients (55% of patients undergoing total thyroidectomy following first-side LOS, including 14 of 18 with persistent LOS) had impaired vocal mobility. One patient had bilateral VCP that did not require tracheostomy, and 2 had postoperative hypoparathyroidism. Of those whose surgery was aborted after first-side LOS, 8 of 22 (36%) underwent completion thyroidectomy at a later stage. In those undergoing completion thyroidectomy, 2 of 8 (25%) had temporary VCP after the second surgery, 2 (25%) had permanent hypoparathyroidism, and 1 (12.5%) developed inoperable cancer. Postoperative VCP was fully reversible in all but 1 patient. Among patients planned for total thyroidectomy who develop first-side LOS, immediate total thyroidectomy may be considered among those who have pressing reasons for same, and where surgical difficulties might be anticipated in a secondary surgery.

A prospective cross-sectional study on hypocalcemia after total thyroidectomy in patients with Graves' disease: insights on secondary hyperparathyroidism.

To investigate the parathyroid function and calcium (Ca) levels in the secondary hyperparathyroidism (SHPT) state in patients with Graves' disease. We examined 31 consecutive patients with Graves' disease without chronic kidney disease, who were treated with total thyroidectomy. The patients were divided into a normal parathyroid hormone (PTH) group (NPTH group; n = 19) with a PTH level ≤ 65pg/mL, and a secondary hyperparathyroidism group (SHPT group; n = 12), with a PTH level > 65pg/mL. The PTH and Ca-related parameters were examined and the risk factors for postoperative hypocalcemia were analyzed. The preoperative Ca level was significantly lower (2.24 ± 0.06 vs. 2.31 ± 0.07mmol/L, p < 0.05) in the SHPT group than in the NPTH group. The reduction in PTH, 1,25-dihydroxyvitamin D (1,25(OH)2D), and Ca levels from the preoperative day to the next morning was significantly greater in the SHPT group than in the NPTH group (p < 0.05). When intraoperative factors were included, the decrease in the PTH level alone was significant. SHPT was a significant factor in determining the extent of PTH reduction. Hyperfunctioning parathyroid glands in the SHPT state were more susceptible to postoperative PTH reduction, which, combined with low preoperative Ca levels, increased the risk of postoperative hypocalcemia in patients with Graves' disease.

Analysis of factors on voice quality in thyroidectomy patients.

Vocal cord paralysis (VCP) is a serious complication in thyroidectomy operations; however, its management remains unclear. The present study evaluated the voice parameters of patients who underwent surgery using Intraoperative Neurophysiologic Monitoring (IONM). A total of 52 patients (41 females and 11 males) who underwent a total thyroidectomy operation were evaluated using objective and subjective voice analysis examinations before and after surgery. Acoustic parameters, such as Fundamental Frequency (F0), Shimmer, Jitter, Noise-to-Harmonic ratio (NHR), and aerodynamic parameters, including S/Z ratio and maximum phonation time (MPT), were analyzed. Objective findings, including the VHI-10 (Voice Handicap Index) and V-RQOL (Voice-Related Quality of Life), were also analyzed. The relationship between voice parameters and IONM values was investigated. The objective analysis (acoustic and aerodynamic parameters) showed no difference (p>0.05). However, the subjective analysis, which involved the VHI-10 and V-RQOL measures, revealed a significant difference before and after the operation (p<0.05). The Spearman correlation analysis showed that the NHR postoperative 1st-month parameter negatively correlated (rho=-0.317, p<0.059), while the F0 postoperative 6th-month parameter positively correlated (rho=0.347) with the amplitude difference before and after dissection (Right R2-R1 difference) for the right RLN measured in IONM. Patients who are planning to undergo a thyroidectomy procedure should undergo voice assessment during both the preoperative and postoperative periods. IONM could improve voice quality outcomes.

Papillary Thyroid Cancer Trends in the Wake of the COVID-19 Pandemic: Is There a Shift toward a More Aggressive Entity?

Globally, the incidence of papillary thyroid cancer (PTC) has been increasing over the last few decades and it has become the second most common cancer in women in the UAE. There is some evidence to suggest that COVID-19 infection might be directly linked to the development of aggressive variants of PTC. The primary goal of this study was to compare the clinical and pathologic characteristics of thyroid cancer patients treated at the largest endocrine surgery center in Abu Dhabi before and after the COVID-19 pandemic outbreak. This retrospective cohort analysis included patients who underwent elective thyroid surgery at Burjeel Hospital between January 2018 and December 2022. Patients were divided into two groups based on when the COVID-19 outbreak started: group one, comprising patients who had surgery between January 2018 and December 2019 (the "pre-pandemic group"), and group two, comprising patients who had surgery between January 2021 and December 2022 (the "post-pandemic group"). In addition to demographic data, clinicopathological factors, such as aggressive cell type, multifocality, tumor size and location, laterality, lympho-vascular invasion, and extrathyroidal extension, were assessed. We utilized the t-paired test for parametric variables and the Chi-square test for the cross-table analysis. During the study, 1141 people had thyroid surgery, with an annual average of 285 procedures. PTC cases recorded in the final histopathological samples rose from 111 in the pre-pandemic era to 182 in the post-pandemic era. Neither the female-to-male gender ratio, which was 90:21 in the pre-pandemic group and 142:40 in the post-pandemic group (p = 0.532), nor the median age, which was 39.1 and 40.1 years, respectively, varied significantly between the two groups. However, there was a significant increase between pre-pandemic and post-pandemic in the aggressive PTC variants (3% vs. 11.5%, p = 0.001), increased poor prognostic factors such as bilateral multifocality (10.8% vs. 32.4%, p = 0.000), as well as increased capsule-vascular tumor invasion (19.8% vs. 27%); on the other hand, the size of the single foci was 17 mm in the pre-pandemic group compared to 13 mm in the post-pandemic group (p = 0.001). A significant rise in unfavorable prognostic markers and aggressive subtypes of PTC was seen post-pandemic in thyroidectomy patients operated on at a leading endocrine surgery center in the United Arab Emirates.

Cine clips increase the detection of thyroid pyramidal lobe in routine thyroid sonogram.

Identification and resection of the thyroid pyramidal lobe is important for thyroid cancer surgery in order to prevent interval cancer in residual thyroid tissue. The purpose of this study was to determine how often a thyroid pyramidal lobe is found in patients with and without previous thyroidectomy and to optimise the protocol for identifying thyroid pyramidal lobes during routine thyroid ultrasonography. In this prospective study, a total of 1579 patients who received routine thyroid ultrasound scans at a single centre were enrolled. A dedicated standard scanning protocol was established containing both static images of the anterior neck superior to the thyroid as well as a transverse cine loop starting from the isthmus to the hyoid bone. The presence and features of thyroid pyramidal lobes were evaluated and compared. Detection rate of thyroid pyramidal lobes in patients without thyroidectomy improved from 39.5% (480/1215) to 49.7% (640/1215) with protocol adding cine-loop as compared to protocol without cine-loop. The cine-loops were particularly helpful in the detection of thyroid pyramidal lobes when it is separated from the main lobe or in thyroidectomy patients. By adding assessment with cine-loop into the dedicated protocol, we have further detected different pathologies occurring on thyroid pyramidal lobes including benign and malignant solid nodules and pseudo-nodules of Hashimoto's thyroiditis. The addition of dynamic assessment with cine-loop increases the detection rate of thyroid pyramidal lobes. By paying attention to the thyroid pyramidal lobe in pre-operative diagnostic sonographic images, we can help to avoid incomplete removal of the thyroid gland during thyroidectomy.

TSH receptor antibody as a predictor of difficult robotic thyroidectomy in patients with Graves’ disease

Thyroidectomy in Graves’ disease can be challenging due to greater thyroid size and vascularity. While thyroid stimulating hormone receptor antibody (TRAb) level is associated with disease severity and thyroid vascularity, its impact on operative outcomes remains unclear. This study aimed to compare challenging factors for robotic thyroidectomy (RT) and open thyroidectomy (OT) in Graves’ disease patients, including TRAb as a predictive factor for difficult thyroidectomy. This retrospective study included Graves’ disease patients who underwent total thyroidectomy between September 2013 and January 2023. The clinical characteristics and operative outcomes were compared between patients who received OT and bilateral axillo-breast approach RT. Factors affecting operation time and estimated blood loss (EBL) were evaluated in both groups using regression analyses. A total of 85 patients received either OT (n = 48) or RT (n = 37). Median thyroid volumes in the OT and RT groups were 72.4 g and 57.6 g, respectively. Operation time was affected by thyroid volume in both groups. Additionally, higher thyroid hormone levels and bilateral central neck node dissection prolonged operation time in the RT group. EBL was marginally associated with thyroid volume in the OT group. However, in the RT group, TRAb level was independently associated with greater EBL (p = 0.04), while no significant association was found with thyroid volume. Predictive factors for difficult thyroidectomy differed by operation approaches. TRAb significantly predicted intraoperative bleeding in RT, while this association was absent in OT. Caution is warranted when performing RT on Graves’ disease patients with high TRAb levels.

Hyoid Bone Movement During Swallowing in Female Thyroidectomy Patients: A Kinematic Ultrasound Study.

The aim of this study was to investigate the measures of displacement, time and velocity of hyoid bone movement in female thyroidectomy patients. Fifty-eight ultrasound videos of 29 women during swallowing were analyzed. The sample was divided into experimental group (EG), composed of 12 women following total or partial thyroidectomy; and control group (CG) of 17 healthy women. The kinematic measures of displacement, time and velocity of hyoid bone displacement were tracked during swallowing of 10ml of liquid (water) and 10ml of thickened liquid (honey) in both groups for comparisons. Additional analysis included bolus consistency effect and relationship with clinical characteristics. Ultrasound videos were analyzed according to a standardized protocol using ImageJ software. Displacement, time and velocity of hyoid movement during swallowing of 10ml of liquid or thickened liquid were not statistically different between female thyroidectomy patients and healthy women. There is no bolus consistency effect on kinematic measures in both groups, but among thyroidectomy patients, velocity of hyoid bone movement is significantly faster in those with swallowing complaints.

Radioiodine ablation after thyroidectomy could be safely abandoned or postponed in selected stage I papillary thyroid carcinoma patients of low-risk group: an observational prospective study

Background. The European Thyroid Association consensus for the management of differentiated thyroid cancer (2006) suggested to avoid radioactive iodine (RAI) after thyroidectomy in patients with unifocal microcarcinoma (≤ 1 cm) with no extension beyond the thyroid capsule and without lymph node metastases. As the new data was collected and the risk stratification was revised, in 2022 the same recommendation was expanded to the patients with microcarcinoma and central neck lymph node involvement. The American Thyroid Association guidelines (2015) advocated no RAI ablation after hemi- or total thyroidectomy for thyroid cancer less than 1 cm with 5 and less micrometastases up to 2 mm in central neck lymph nodes as this strategy has no negative impact on the disease prognosis. In low-risk patients, no sufficient evidence of the obligatory postsurgical radioiodine ablation has been yet demonstrated. The aim of our study was to reveal whether RAI after thyroidectomy can be abandoned or postponed until the disease progression is confirmed in low-risk patients. Materials and methods. Two groups of patients (30 per group, 60 in total) with papillary microcarcinoma Т1N1a (5 and less level VI micrometastases up to 2 mm) were observed during a 5-year follow-up. In the first group, patients received 100 mCi (3.75 GBq) I131 shortly after total thyroidectomy while in the second group, postponed RAI was applied when progression signs were observed (elevated serum thyroglobulin level and US/CT suspected findings) after thyroid surgery. Results. After 5 years, no significant difference between groups was observed regarding post-RAI local recurrences (one in the first group and two in the second group) and/or distant metastases (t-test, p = 0.58). All cases of neck recurrences were treated with subsequent surgical excision, with no new data of progression within the specified follow-up. Conclusions. RAI adjuvant therapy for papillary thyroid carcinoma Т1N1a may not be necessary for patients with small number of level VI micrometastases. Local and distant metastases revealed during the careful follow-up by thyroglobulin level elevation and when using visualization techniques can be effectively treated with postponed RAI therapy and/or surgery.

The impact of coexisting Hashimoto's thyroiditis on the feasibility of endoscopic thyroidectomy in papillary thyroid carcinoma

Objective：The safety of endoscopic thyroidectomy in patients with Hashimoto's thyroiditis (HT) is a matter of concern. This study aimed to assess the effect of concomitant HT on the feasibility of endoscopic thyroidectomy in patients with papillary thyroid carcinoma (PTC). MethodsThis study is an observational, retrospective study. All patients were histopathologically diagnosed with HT. The study group consisted of 44 patients (40 %) with PTC who also had HT, whereas the remaining 66 patients (60%) without HT were assigned to the control group. The number of dissected lymph nodes, mean operation time, thyroid volume, blood loss, TSH level, and postoperative complications were recorded and statistically analysed. ResultsOne patient underwent conversion to open thyroidectomy because of recurrent laryngeal nerve (RLN) transection. Another patient required reoperation owing to postoperative haemorrhage. Statistically significant differences were observed in mean operation time (105.4 ± 10.7 vs 98.2 ± 7.4 min, P = 0.0001),mean thyroid lobe volume (12.2 ± 5.8 vs 9.6 ± 3.5 mL [mL], P = 0.0041), TSH level(4.1 ± 1.5 mIU/L vs 3.4 ± 0.9 mIU/L, P ＝ 0.0028), and the number of dissected lymph nodes between groups (4.1 ± 1.5 vs 3.4 ± 0.9,P = 0.0028). The estimated mean blood loss (31.5 ± 6.8 vs 29.5 ± 3.9 mL, P = 0.0529) and rate of complications (15.9% vs 10.6%, P = 0.4136) did not show statistically significant differences between groups. ConclusionThe coexistence of PTC and HT increases the operation time and difficulties in endoscopic thyroidectomy but does not affect postoperative outcomes. Endoscopic thyroidectomy can be safely performed with acceptable complication rates.

Optimizing Levothyroxine Replacement: A Precision Dosage Model for Post-Thyroidectomy Patients.

Thyroidectomy is commonly performed for benign or malignant thyroid tumors, often resulting in hypothyroidism. Levothyroxine (LT4) supplementation is crucial to maintain hormone levels within the normal range and suppress TSH for cancer control. However, determining the optimal dosage remains challenging, leading to uncertain outcomes and potential side effects. We analyzed clinical examination data from 510 total thyroidectomy patients, including demographic information, blood tests, and thyroid function. Using R, we applied data preprocessing techniques and identified 274 samples with 98 variables. Principal Component Analysis, correlation analysis, and regression analysis were conducted to identify factors associated with optimal LT4 dosage. The analysis revealed that only eight variables significantly influenced the final satisfactory dosage of LT4 in tablets: Benign0/Malignant1 (benign or malignant), BQB (electrophoretic albumin ratio), TP (total protein), FDP (fibrin degradation products), TRAB_1 (thyroid-stimulating hormone receptor antibody), PT (prothrombin time), MONO# (monocyte count), and HCV0C (hepatitis C antibody). The resulting predictive model was: . Parameters such as benign/malignant status, TRAB_1, and BQB ratio during medication can serve as observational indicators for postoperative LT4 dosage. The calculated linear model can predict the LT4 dosage for patients after thyroidectomy, leading to improved treatment effectiveness and conserving medical resources.

Inflammatory Profile Assessment in a Highly Selected Athyreotic Population Undergoing Controlled and Standardized Hypothyroidism.

Background: Hypothyroidism (hT) presents heterogeneous symptoms and findings. Evidence on this topic comes mainly from heterogeneous populations in terms of disease duration, residual thyroid function, and comorbidities. Therefore, it would be useful to assess systemic inflammation in a homogeneous hT population. The aim of this study was to investigate inflammation in a population that underwent standardized controlled hT. Methods: We recruited thyroidectomized patients diagnosed with thyroid cancer who were otherwise fit and healthy, showing hypothyroidism before I131 treatment using a standard protocol of LT4 withdrawal. The blood inflammatory indexes (BIIXs) (i.e., NLR, PLR, MLR, SII, SIRI, and AISI) were calculated using the blood tests collected just before I131 administration. Patients were divided according to sex, BMI, and thyroglobulin. The relationships between the BIIXs, age, and thyroid hormones were also investigated. Results: We included 143 patients. The median age of the sample was 43 years. The BIIX median values showed significant differences based on sex, BMI, and thyroglobulin levels (p < 0.05). No significant correlations were found between the BIIXs and age, TSH, FT4, and FT3. Conclusions: This study shows the BIIX median values of a population which underwent standardized hT. It suggests a role for some BIIXs in the evaluation of hypothyroidism in obese people and as hypothetical prognostic markers for thyroid cancer.

Assessment of Patients' Quality-of-Life Post-Thyroidectomy.

The assessment of quality of life (QOL) after thyroidectomy has been a focus of medical research, aiming to understand its impact on patients' overall well-being and functional status. Studies have examined the physical, psychological, and social dimensions of QOL, providing valuable insights into the outcomes of thyroidectomy and improving patient care.The aim of the study is to evaluate the long-term impact of different aspects of patients' quality of life post-thyroidectomy. This cross-sectional study was conducted in Taif City and included 100 participants post-thyroidectomy. Data were collected from medical records and telephone interviews using the modified Arabic version of the EROTC QLQ-H&N43 questionnaire. The collected data were analyzed using R software version 4.2.2. The majority of the 100 participants were female (76%), and most were over 50 years old (38%). The types of surgery performed included hemithyroidectomy (36%), subtotal thyroidectomy (6%), and total thyroidectomy (58%). Participants reported difficulties related to their senses, body satisfaction, sexual satisfaction, eating, speaking, and social interactions. Pain in the mouth and jaw, as well as swallowing difficulties, showed variations among the surgery groups. Other symptoms, such as tooth problems, dry mouth, and swelling in the neck, did not differ significantly among the groups. Numbness in the hands or feet was associated with a subtotal or total thyroidectomy. Difficulties with enjoying meals, eating in front of others, and communication issues showed variations among the surgery groups. This study provided insights into the QOL of thyroidectomy survivors in Taif City. Participants reported challenges related to sensory, body, and sexual issues, as well as difficulties with eating, speaking, and social interactions. The findings highlight the need for interventions and support to address these challenges and optimize the QOL of thyroidectomy patients. Furthermore, research is warranted to explore specific factors contributing to these difficulties and to develop targeted interventions for better patient outcomes.

Adhesion Reduction Agent Guardix-SG® Versus MegaShield® for Postoperative Swallowing Function Analysis in Thyroidectomy Patients.

Antiadhesion products are essential for postoperative care in patients after thyroidectomy by providing a physical barrier to cover the exposed tissue and thus preventing abnormal adhesion of adjacent tissues. Since thyroidectomy may result in swallowing difficulties arising from damage or inflammation of the surrounding tissues, the use of antiadhesion agents such as MegaShield® or Guardix-SG® will help reduce scar formation. This may thus improve postoperative swallowing function in patients. Patients were enrolled and followed up between October 4, 2018, and March 26, 2020. Patients during the postoperative follow-up sessions were randomly allocated to the standard care with Guardix-SG® and clinical trial medical device application group with MegaShield® (test group) in a 1:1 ratio by the permuted block randomization method. Patient performance on penetration aspiration scale (PAS), National Institutes of Health-Swallow Safety Scale (NIH-SSS), videofluoroscopic dysphagia scale (VDS), Dynamic Imaging Grade of Swallowing Toxicity (DIGEST) based on Videofluoroscopic swallowing study (VFSS) were collected. Nonadhesion-reducing agent patient data were used as a control group. No statistical significance was shown (P > .05) between the 2 groups of MegaShield® and Guardix-SG® in various phases from thick semisolid, thin semisolid to liquid for both PAS and NIH-SSS. Several statistical significances were reported in the results comparing various criteria of PAS, NIH-SSS, VDS at different oral and pharyngeal phases, and DIGEST in all 3 stages among MegaShield®, Guardix-SG®, and nonadhesion-reducing agent group. These results prove the noninferiority of MegaShield® compared with Guardix-SG® as an antiadhesion agent in postthyroidectomy care.
