Sepsis and Septic Shock in Patients Undergoing Thyroidectomy: Incidence, Risk Factors, and Outcomes.

INTRODUCTION: Postoperative sepsis represents a rare complication following thyroidectomy. We aimed to explore the incidence, risk factors, sources, and outcomes of postoperative sepsis and septic shock among adult patients undergoing thyroidectomy. METHODS: Data from the American College of Surgeons National Surgical Quality Improvement Program were used in this retrospective cohort study. Patients aged ≥18 y who underwent elective thyroidectomy between 2005 and 2019 were included. Multivariable binary logistic regression models were computed to explore risk factors and outcomes of 30-d sepsis and septic shock. RESULTS: Among the 180,373 included patients, 0.1% developed sepsis or septic shock. Male gender, low body mass index, American Society of Anesthesiologists classes 3-5, functional dependence, smoking, diabetes mellitus, pulmonary disease, inpatient surgery, malignant indication, clean-contaminated wound classification, and operation time ≥150 min were significant risk factors for development of sepsis or septic shock. Common infectious sources of sepsis included surgical site infections (29.6%), pneumonia (18.6%), urinary tract infections (16.2%), and multiple infections (6.9%). Patients with postoperative sepsis or septic shock were significantly more likely to develop complications, including wound disruption, stroke, cardiac and renal complications, thromboembolism, prolonged length of stay, unplanned reoperation, and mortality. CONCLUSIONS: Sepsis is rare following thyroidectomy. Our study provides insight into risk factors and procedural characteristics which may contribute to the development of postoperative sepsis or septic shock in this population.

Guideline From the Brazilian Society of Surgical Oncology and Brazilian College of Surgeons in Preventing and Managing Acute Hypoparathyroidism After Thyroid Surgery.

The risk of hypoparathyroidism and hypocalcemia is a critical concern in thyroid surgery. Preserving parathyroid gland vascularization during surgery is essential for effective prevention. Preoperative and postoperative management, including calcium and Vitamin D supplementation, is paramount. Measurement of parathyroid hormone levels after surgery is the best predictor of hypoparathyroidism. This guideline offers recommendations for the prevention, diagnosis, and treatment of acute hypoparathyroidism and hypocalcemia after thyroid surgery.

Comparison of clinical and patient-reported outcomes in patients with benign euthyroid solitary nodules after ultrasound-guided percutaneous microwave ablation and endoscopic thyroidectomy.

BACKGROUND: Percutaneous ultrasound-guided microwave ablation (MWA) for benign solid thyroid nodules is the newest modality for treatment. However, the differences in treatment outcomes between MWA and endoscopic thyroidectomy vestibular approach (TOETVA) for patients with benign euthyroid solitary nodules remain unknown. We are sharing initial results from our prospective study. METHODS: Prospective study between January 2022 and December 2023 was conducted and data were noted at 3 time points in patients planned for treatment (Preoperative, 1 week, and 12 months). Main outcome measures were clinical outcome and comparison of thyroid-related quality of life using the ThyPRO-39hin and swallowing-related quality of life using the SWAL-QoL. RESULTS: Of the 36 included patients, 20 patients underwent TOETVA and 16 underwent MWA. Both the groups were comparable in terms of demographic and clinicopathological profiles. The nodule volume reduction rate of patients at 12 months after MWA was 75.10% and 100% for TOETVA. The mean preoperative ThyPRO-39hin and SWAL-QoL scores were comparable in all domains between the two groups. Mean ThyPRO-39hin and SWAL-QoL scores on postoperative day 7 were significantly better in the MWA group in domains impaired social life (p < 0.0001) and impaired daily life (p = 0.0002). However, at the end of 12 months, mean ThyPRO-39hin and SWAL-QoL scores became significantly better in the TOETVA group as compared to the MWA group. CONCLUSION: Our findings suggest that transoral endoscopic thyroidectomy results in significant superior clinical outcome, thyroid-related quality of life, and swallowing-related quality of life in the long term.

Outcomes and predictors of complications of thyroidectomy in a scarce resource setting: Retrospective cross-sectional study.

BACKGROUND: Outcomes and predictors of complications of thyroidectomy are diverse and have been extensively studied, but data from our country and other African countries with high disease burdens are limited. OBJECTIVE: To evaluate the outcomes and predictors of complications of thyroidectomy among operated patients. METHOD: Single institution retrospective cross-sectional study was conducted by reviewing charts from 365 patients who had undergone thyroidectomy on an elective basis between March 2018-February 2022. All patients who were admitted and underwent thyroidectomy were included in this study. Bivariate and multivariate logistic regressions were used to identify risk factors. P-value <0.05 was considered statistically significant. RESULT: Overall, post-thyroidectomy complications occurred in 17 % of the cases. The two most common complications were hypocalcemia and voice change; the latter being due to injury of either external branch of superior laryngeal nerve or recurrent laryngeal nerve with an incidence of 4.9 % and 2.5 % respectively. Thyroidectomy performed by surgical residents and having total thyroidectomy were significantly associated with overall complications of thyroidectomy. Total thyroidectomy was found to be a risk factor for postoperative hypocalcemia (AOR = 12.24 (95%CI: 4.53, 19.65); P = 0.02). Younger age of the patient (AOR =0.3(95%CI, 0.12,0.51)) and prolonged duration of presentation (AOR = 2.53(95%CI, 1.17,7.76)) were detected predictors of voice change due to injury of either external branch of superior laryngeal nerve or recurrent laryngeal nerve. CONCLUSION: The rate of thyroidectomy complications is relatively similar to other studies. In this study demographic and clinical factors associated with increased risk of complications after thyroid surgery were identified. This information will be useful for educating patients about the risks of thyroid surgery.

Immediate Ansa cervicalis-to-recurrent laryngeal nerve low-tension anastomosis: A new technique for phonation recovery and bilateral anastomoses to avoid tracheotomy.

OBJECTIVE: This case series study investigated the outcomes of an innovative approach, ansa cervicalis nerve (ACN)-to-recurrent laryngeal nerve (RLN) low-tension anastomosis. METHODS: Patients who received laryngeal nerve anastomosis between May 2015 and September 2021 at the facility were enrolled. The inclusion criteria were patients with RLN dissection and anastomosis immediately during thyroid surgery. Exclusion criteria were cases with anastomosis other than cervical loop-RLN anastomosis or pronunciation recovery time > 6 months. Patients admitted before January 2020 were assigned to group A which underwent the conventional tension-free anastomosis, and patients admitted after January 2020 were group B and underwent the innovative low-tension anastomosis (Dong's method). RESULTS: A total of 13 patients were included, 11 patients received unilateral surgery, and 2 underwent bilateral surgery. For patients who underwent unilateral anastomosis, group B had a significantly higher percentage of normal pronunciation via GRBAS scale (83.3 % vs. 0 %, p = 0.015) and voice handicap index (66.7 % vs. 0 %, p = 0.002), and shorter recovery time in pronunciation (median: 1-day vs. 4 months, p = 0.001) than those in group A after surgery. CONCLUSIONS: ACNs-to-RLN low-tension anastomosis with a laryngeal segment ≤1 cm (Dong's method) significantly improves postoperative pronunciation and recovery time. The results provide clinicians with a new strategy for ACN -to-RLN anastomosis during thyroid surgery.

Effect of the intraoperative head hypsokinesis on sore throat after thyroid surgery: a randomized controlled trial.

PURPOSE: Postoperative sore throat (POST) after thyroidectomy is a major concern.A roll is typically inserted under the shoulder to achieve head hypsokinesis and neck extension to better expose the surgical site during thyroid surgery. However, POST and impaired voice function have been attributed to neck overextension. This study aimed to explore the rational angle of head hypsokinesis that both reduced sore throat intensity and protects voice function after thyroid surgery. METHODS: A total of 210 patients who underwent thyroidectomy were enrolled and randomized into high-tilt (Group H) and low-tilt angle groups (Group L). The primary outcome was the incidence of POST 6 h after surgery. Secondary outcomes included the severity of postoperative pharyngeal pain, voice function, swallowing pain, and coughing. RESULTS: The incidence of POST 6 h after thyroidectomy was significantly lower in Group L than that in Group H. In addition, the intensity of postoperative sore throat and swallowing pain was more severe in Group H. A lower degree of head hypsokinesis in Group L prevented transient postoperative voice injury. CONCLUSIONS: A lower degree of head hypsokinesis effectively mitigated sore throat severity after thyroidectomy and improved postoperative voice function. REGISTER INFORMATION: The trial was registered in the Chinese Clinical Trial Registry on 21 June 2022 (ChiCTR2200061329). The trial is registered at https://www.chictr.org.cn/showproj.html?proj=166254 .

Efficacy and safety of fibrin sealant application in patients undergoing thyroidectomy: a systematic review and meta-analysis.

Various studies have focused on the application of fibrin sealants (FS) in thyroid surgery. Utilizing a meta-analysis, this systematic review analyzed the findings of recent randomized controlled trials on the safety and efficacy of FS in patients who underwent thyroidectomy. The Cochrane Library, Web of Science, Embase, PubMed, and Medline databases were searched for relevant studies, without any language restrictions. Seven randomized controlled trials were included in the originally identified 69 studies. Overall, 652 patients received FS during thyroid surgery; their outcomes were compared with those of conventionally treated patients. The primary outcomes were total volume of wound drainage, length of hospitalization, and operative time. Significant differences were observed in the total volume of wound drainage (mean deviation (MD): -29.75, 95% confidence interval (CI): -55.39 to -4.11, P = 0.02), length of hospitalization (MD: -0.84, 95% CI: -1.02 to -0.66, P < 0.00001), and surgery duration (MD: -7.60, 95% CI: -14.75 to -0.45, P = 0.04). Secondary outcomes were seroma and hypoparathyroidism development. The risk of hypoparathyroidism did not differ between the FS and conventional groups (I = 0%, relative risk = 1.31, P = 0.38). Analysis of "seroma formation that required invasive treatment" indicated that FS showed some benefit (I2 = 8%, relative risk 0.44, P = 0.15). Heterogeneity among the different trials limited their conclusions. The meta-analysis showed that although FS use did not significantly reduce seroma or hypoparathyroidism incidence in patients after thyroidectomy, it significantly reduced the total drainage volume, length of hospitalization, and duration of surgery.

Evolution in the management of thyroid surgery over a period of 15 years in a Belgian center.

BACKGROUND: Guidelines for thyroid surgery have evolved to reflect advances in medical knowledge and decrease the overdiagnosis of low-risk thyroid cancer. Our goal was to analyze the change made in operative thyroid management and the impact on thyroid cancer diagnosis. BACKGROUND: Guidelines for thyroid surgery have evolved to reflect advances in medical knowledge and decrease overdiagnosis of low risk thyroid cancer. Our goal was to study the evolution, over a long period, of pre- and postoperative management and the influence on histological cancer diagnosis and, more particularly, microcancer. METHODS: In this retrospective cohort study, we included 891 consecutive patients who underwent thyroid surgery between 2007 and 2020. RESULTS: Respectively 305, 290 and 266 patients underwent surgery over the 3 periods of 2007-2010, 2011-2015 and 2016-2020. In all three periods, women represented approximately 70% of the population, and the mean age was 54 years old (range: 67). Most surgeries (90%) involved total thyroidectomies. Over the study period, the proportion of preoperative fine needle aspiration (FNA) increased from 13 to 55%, p < 0,01. Cancer was found in a total of 116 patients: 35 (11%) patients between 2007 and 2010, 50 (17%) between 2011 and 2015 and 32 (12%) between 2016 and 2020 (p = 0.08). For all 3 periods, papillary thyroid cancer (PTC) was the most prevalent, at approximately 80%. The proportion of thyroid cancer > T1a increased significantly from 37% (2011-2015 period) to 81% (2016-2020 period), p = 0.001. Patients treated with radioiodine remained relatively stable (approximately 60%) but were more frequently treated with a low dose of radioiodine (p < 0.01) and recombinant human TSH (p < 0.01). Operative thyroid weight decreased over time in all but the low-risk T1a PTC cases. CONCLUSIONS: Over a period of 15 years and according to the evolution of recommendations, the care of patients who underwent thyroid surgery changed with the increased use of preoperative FNA. This change came with a decrease in low-risk T1a PTC.

The Effect of Thyroid Surgery on the Accuracy of Palpation-Based Cricothyroid Membrane Identification in Female Patients: A Prospective Observational Cohort Study.

Background and Objectives: This study examined how a history of thyroid surgery impacts the precision of cricothyroid membrane (CTM) identification through palpation (validated by ultrasound) in female patients visiting the operating room for surgeries unrelated to neck procedures. Materials and Methods: This prospective observational cohort study enrolled adult female patients undergoing elective non-neck surgery, dividing them into control (no thyroid surgery history; n = 40) and experimental (with thyroid surgery history; n = 40) groups. CTM identification was performed by palpation and confirmed via ultrasound. Results: There were no significant differences between two groups in the demographic characteristics of the patients. The success rate and accuracy of CTM identification through palpation were significantly higher in the control group compared to the experimental group (90% vs. 42.5%, respectively; p < 0.001). For female patients with a history of thyroid surgery, the sensitivity of successful CTM palpation was 42.5%, and the specificity was 10%. These figures are based on the calculated true positives (17), false positives (36), true negatives (4), and false negatives (23). Conclusions: Thyroid surgery history in female patients may hinder the accurate palpation-based identification of the CTM, suggesting a need for enhanced clinical practices and considerations during airway management training.

Systematic review with meta-analysis of intraoperative neuromonitoring during thyroid reoperation.

Objective: Recurrent laryngeal nerve (RLN) injury is a serious complication during thyroid reoperation. Intraoperative neuromonitoring (IONM) is one of the means to reduce RLN paralysis. However, the role of IONM during thyroidectomy is still controversial. The aim of this study was to assess whether the IONM could reduce the incidence of RLN injury during thyroid reoperation. Methods: We performed a systematic review to identify studies in English language which were published between January 1, 2004, and March 25, 2023 from PubMed, EMBASE, and Cochrane Library, comparing the use of IONM and Visualization Alone (VA) during thyroid reoperation. The RLN injury rate was calculated in relation to the number of nerves at risk. All data were analyzed using Review Manger (version 5.3) software. The Cochran Q test (I2 test) was used to test for heterogeneity. Odds ratios were estimated by fixed effects model or random effects model, according to the heterogeneity level. Results: Eleven studies (3655 at-risk nerves) met criteria for inclusion. Data presented as odds ratio(OR) and their 95% confidence intervals(CI). Incidence of overall, temporary, and permanent RLN injury in IONM group were, respectively, 4.67%, 4.17%, and 2.39%, whereas for the VA group, they were 8.30%, 6.27%, and 2.88%. The summary OR of overall, temporary, and permanent RLN injury compared using IONM and VA were, respectively, 0.68 (95%CI 0.4-1.14, p=0.14), 0.82 (95%CI 0.39-1.72, p=0.60), and 0.62 (95%CI 0.4-0.96, p=0.03). Conclusions: The presented data showed benefits of reducing permanent RLN injury by using IONM, but without statistical significance for temporary RLN injury.

Thyroid surgery in the elderly: a surgical cohort.

PURPOSE: The need for thyroid surgery in the elderly is rising due to an ageing population, the liberal use of imaging studies, and the increasing prevalence of thyroid nodules and cancer with age. Data on surgical outcomes in this population are scarce and conflicting, but essential to assess safety of short-stay surgery. This study aims to compare surgical outcomes by age. METHODS: All consecutive patients undergoing thyroid surgery from January 2010 to July 2021 in a large tertiary referral centre for endocrine surgery were included in this surgical cohort. The indication for surgery, surgical morbidity (hypocalcaemia, bleeding, recurrent laryngeal nerve (RLN) palsy), and length of hospital stay were assessed in three age groups (young: 18-64y, older: 65-74y, and the elderly: 75 years and older). RESULTS: A total of 2,030 patients (1,499 young, 370 older, and 161 elderly) were included. The indication for surgery was significantly different, with the main indications in the elderly being multinodular goitre (70.2% vs. 47.7% in young patients) and thyroid cancer (9.9% vs. 7.0%). Reintervention for bleeding was more often required in the older (4.6%) and the elderly (2.5%) patients (vs. 1.4%). There was no difference in the proportion of hypocalcaemia or RLN palsy. The length of hospital stay was significantly longer in the elderly (length of stay longer than one day 43.5% vs. 9.8%). CONCLUSION: Thyroid surgery in patients aged 75 years and older is a safe procedure with morbidity comparable to younger patients. However, the risk of reintervention for bleeding is higher, rendering ambulatory surgery not advisable. TRIAL REGISTRATION: Researchregistry6182 on October 29th 2020, retrospectively registered.

Impact of direct laryngoscopy vs. videolaryngoscopy on signal quality of recurrent laryngeal nerve monitoring in thyroid surgery: a randomised parallel group trial.

In thyroid surgery, intra-operative neuromonitoring signals of the recurrent laryngeal nerve can be detected by surface electrodes on a tracheal tube positioned at the vocal fold level. The incidence of difficult tracheal intubation in patients undergoing thyroidectomy for nodular goitre ranges from 5.3% to 20.5%. The aim of this study was to compare videolaryngoscopy with conventional direct laryngoscopy as methods for proper placement of the surface electrode to prevent insufficient intra-operative nerve signal quality. In this prospective randomised trial, adult patients requiring tracheal intubation during thyroid surgery were randomly allocated to two groups of C-MAC® (Macintosh style blade) videolaryngoscope or direct laryngoscopy using the Macintosh laryngoscope. Primary outcome was the incidence of insufficient signal electromyogram amplitude level (< 500 µV) after successful tracheal intubation. A total of 260 (130 per group) participants were analysed. An insufficient signal was more frequent with direct laryngoscopy (35/130, 27%), compared with C-MAC (12/130, 9%, p < 0.001). First-pass tracheal intubation success rate was lower with direct laryngoscopy (86/130 (66%)) compared with the C-MAC (125/130 (96%)) (p < 0.0001). Cormack and Lehane grade ≥ 3 was observed more frequently with direct laryngoscopy (16/130 (12%)), compared with the C-MAC (0/130, (0%)) (p < 0.0001). The results suggest that videolaryngoscopy has an impact on the quality of the initial intra-operative neuromonitoring signal in patients undergoing thyroid surgery, and this technique can provide optimised surface electrode positioning.

Trends, Influence Factors, and Doctor-Patient Perspectives of Web-Based Visits for Thyroid Surgery Clinical Care: Cross-Sectional Study.

BACKGROUND: In recent years, the new generation of telecommunication technologies has profoundly changed the traditional medical industry. To alleviate the medical difficulties faced by patients with thyroid diseases, hospitals have opened web-based visits and actively combined online-to-offline outpatient services. OBJECTIVE: This study aims to explore differences between office and web-based outpatient services from doctors' and patients' perspectives, illustrate the effect of the COVID-19 pandemic on outpatient services, and provide clues for improving the online-to-offline mode of care for patients with thyroid diseases. METHODS: We collected the complete web-based and office outpatient records of the Thyroid Surgery Center of West China Hospital. A total of 300,884 completed patient encounters occurred (201,840 office visits and 99,044 web-based visits) from January 1, 2019, to May 31, 2022. We performed logistic regression to evaluate the association between the chosen visit type and patients' sociodemographic characteristics. RESULTS: The number of web-based visits rapidly increased since March 2020 and reached 45.1% (4752/10,531) of all encounters in December 2021. The COVID-19 pandemic dramatically accelerated the development of web-based visits. Web-based visits were preferred by patients 18-45 years old (odds ratio [OR] 2.043, 95% CI 1.635-2.552, P<.001), patients with relatively high-paying jobs (technical staff: OR 1.278, 95% CI 1.088-1.479, P=.003; office clerk: OR 1.25, 95% CI 1.07-1.461, P=.005; national public servant: OR:1.248, 95% CI 1.042-1.494, P=.02), and patients living in Sichuan Province (excluding Chengdu; OR 1.167, 95% CI 1.107-1.23, P<.001). The medicine cost (P<.001) and examination cost (P<.001) of office visits were significantly higher than those of web-based visits. CONCLUSIONS: Web-based outpatient visits have increased rapidly in recent years, and the COVID-19 pandemic has boosted their development. The preference for web-based visits was influenced by the socioeconomic and demographic characteristics of both patients and doctors.

The Impact of Glucocorticoid Treatment on Hypocalcemia Following Thyroid Surgery: A Systematic Review and Meta-Analysis.

Patients undergoing thyroidectomy often develop hypocalcemia. While there is evidence suggesting that the prophylactic administration of dexamethasone in patients undergoing thyroidectomy can reduce the risk of postoperative complications including nausea, vomiting, and pain, it remains uncertain as to whether such treatment has a similar impact on hypocalcemia risk. Here, randomized controlled trials (RCTs) focused on comparing the risk of postoperative hypocalcemia in thyroidectomy patients that either were or were not administered a single preoperative dose of dexamethasone were systematically evaluated. These RCTs were identified by searching the Medline, PubMed, Embase, and Cochrane Library for all relevant publications as of April 2023. Primary study outcomes included biochemical hypocalcemia and symptomatic hypocalcemia incidence within 24 h after thyroidectomy, while the incidence of permanent hypocalcemia was a secondary outcome in this analysis. Random-effects models were used for all comparisons in this meta-analysis. In total, 8 RCTs enrolling 1666 patients were incorporated when conducting this meta-analysis. Relative to placebo control treatment, dexamethasone administration was associated with significant reductions in the rates of postoperative symptomatic hypocalcemia (OR = 0.40; 95%CI 0.16-1.00; p = 0.050) and biochemical hypocalcemia (OR = 0.34;95%CI 0.14-0.83; p = 0.020 (p < 0.05). No differences were detected between these groups with respect to the incidence of permanent hypocalcemia, and no trials revealed any evidence of glucocorticoid-associated complications. Significant heterogeneity was detected among studies, but the exclusion of any single study did not significantly alter study outcomes. The present pooled analyses suggested that one preoperative dexamethasone dose was sufficient to reduce the odds of thyroidectomy patients developing biochemical or symptomatic hypocalcemia within 24 h after the procedure. The prophylactic administration of steroids was both safe and effective, suggesting that it warrants consideration as a component of routine clinical care. However, additional prospective work will be vital to validate the efficacy of dexamethasone as a means of preventing objective hypocalcemia in this patient population.

Single-port endoscopy-assisted thyroidectomy via cervical gas-insufflation approach for papillary thyroid carcinoma: A pilot retrospective comparative study.

PURPOSE: This study aims to investigate the safety and efficacy of our novel technique of single-port endoscopy-assisted thyroidectomy via cervical gas-insufflation approach (SPEAT, also called the Huang procedure) in the treatment of papillary thyroid carcinoma (PTC). MATERIALS AND METHODS: We perform a retrospective comparative study from a prospectively maintained database. A cohort of 82 patients with PTC who underwent total thyroidectomy and central neck dissection were included. Of these patients, 48 underwent SPEAT and 34 underwent conventional open thyroidectomy (COT). The differences in surgical outcome and oncological completeness were compared. RESULTS: Compared with the COT group, the SPEAT group had obviously shorter incision (P < 0.001), less postoperative pain (P = 0.036), better cosmetic satisfaction (P = 0.001)and slightly longer operating time (P = 0.041). In intraoperative bleeding, postoperative drainage, postoperative hospital stay, surgical complications, number of dissected or positive lymph nodes per patient, and postoperative non-stimulated or stimulated thyroglobulin levels, there were no significant differences. CONCLUSIONS: SPEAT (the Huang procedure) is a minimally invasive, safe and oncologically complete surgical option for PTC in selected patients.

Efficacy of four different hemostatic agents in thyroid surgery in reducing the amount of post-operative fluid collection.

PURPOSES: Postoperative bleeding remains a life-threatening complication in thyroid surgery. The aim was to assess the efficacy of four different hemostatic agents, Collagen-Fibrinogen-Thrombin Patch (CFTP) in two sizes (3 × 2.5 cm and 9.5 × 4.8 cm), polysaccharide particles (1 g) and Cellulose Gauze (2.5 × 5 cm) on postoperative drainage volume (DV) compared to a control group. METHODS: We included from October 2007 until Mai 2011, 150 patients (30 per group) for this monocentric, retrospective case-controlled study. Patients were scheduled for a hemithyroidectomy or thyroidectomy. The primary endpoint was the postoperative DV within the first 24 h, secondary the incidence of adverse events. RESULTS: There were no difference in demographic parameters. The mean DV (± SD) was 51.15 (± 36.86) ml in the control, 50.65 (± 42.79) ml in small (3 × 2.5 cm), 25.38 (± 23.99) ml in large CFTP (9.5 × 4.8 cm), 53.11 (± 39.48) ml in the polysaccharide particles and 48.94 (± 30.59) ml in the cellulose gauze group. DV was significantly reduced with the large CFTP (p < 0.05) compared to all other groups. There were no adverse events. CONCLUSIONS: We were able to demonstrate a significant reduction in the DV for the large CFTP group compared to the other collectives. Although this as being associated with not inconsiderable costs and we would only recommend its use for high-risk patients only.

Analysis of preoperative influential factors and construction of a predictive nomogram of difficult thyroidectomy.

OBJECTIVE: To explore the preoperative influential factors of difficult thyroidectomy and establish a preoperative nomogram for predicting the difficulty of thyroidectomy. METHODS: A total of 753 patients who underwent total thyroidectomy with central lymph node dissection between January 2018 and December 2021 were retrospectively enrolled in this study and randomly divided into training and validation groups at a ratio of 8:2. In both subgroups, the patients were divided into difficult thyroidectomy and nondifficult thyroidectomy groups based on the operation time. Patient age, sex, body mass index (BMI), thyroid ultrasound, thyroid function, preoperative fine needle aspiration (FNA), postoperative complications and other data were collected. Logistic regression analysis was performed to identify the predictors of difficult thyroidectomy, and a nomogram predicting surgical difficulty was created. RESULTS: Multivariate logistic regression analysis demonstrated that male sex (OR = 2.138, 95% CI 1.055-4.336, p = 0.035), age (OR = 0.954, 95% CI 0.932-0.976, p < 0.001), BMI (OR = 1.233, 95% CI 1.106-1.375, p < 0.001), thyroid volume (OR = 1.177, 95% CI 1.104-1.254, p < 0.001) and TPO-Ab (OR = 1.001, 95% CI 1.001-1.002, p = 0.001) were independent risk factors for difficult thyroidectomy. The nomogram model incorporating the above predictors performed well in both the training and validation sets. A higher postoperative complication rate was found in the difficult thyroidectomy group than in the nondifficult thyroidectomy group. CONCLUSION: This study identified independent risk factors for difficult thyroidectomy and created a predictive nomogram for difficult thyroidectomy. This nomogram may help to objectively and individually predict surgical difficulty before surgery and provide optimal treatment.

The efficacy and safety of opioid-free anesthesia combined with ultrasound-guided intermediate cervical plexus block vs. opioid-based anesthesia in thyroid surgery-a randomized controlled trial.

PURPOSE: In the context of the current comfort medicine and enhanced recovery after surgery, there is a demand for a new anesthesia method to reduce adverse reactions and accelerate recovery after surgery. This randomized controlled trial aimed to compare the efficacy and safety between opioid-free anesthesia (OFA) combined with ultrasound-guided intermediate cervical plexus block (ICPB) and opioid-based anesthesia in patients after thyroid surgery. METHODS: In this study, 75 patients scheduled for thyroid surgery under general anesthesia were randomly allocated into two groups. The primary outcome included the incidence of nausea within 24 h after surgery. The main secondary outcomes included the incidence of vomiting and the visual analog score (VAS) scores within 24 h after surgery as well as the quality of recovery 40 questionnaires (QoR-40) scores 24 h after surgery. RESULTS: In the OFA group, the incidence of postoperative nausea was 6.1%, compared to 39.4% in the control group (p = 0.001). No patient presented with postoperative vomiting in the OFA group, while 15.2% of patients suffered from postoperative vomiting in the control group (p = 0.063). The VAS scores of patients in the postanesthetic care unit (PACU) and 2 h, 4 h, and 6 h after surgery were lower in the OFA group, and the difference is statistically significant. Besides, the VAS scores of patients at rest (p = 1.000) and during swallowing (p = 1.000) 24 h after surgery were comparable. CONCLUSION: Compared with opioid-based anesthesia, the OFA combined with the ultrasound-guided ICPB can better improve patients' postoperative recovery, reduce nausea, and decrease pain scores.

Transoral endoscopic thyroidectomy vestibular approach, adaptation of modern surgical technique in a developing country.

Conventional thyroidectomy has been the standard technique for over 100 years but has the drawback of leaving a scar on the neck. As such, the demand for minimally invasive endoscopic thyroid surgery is rapidly growing as patients are becoming more and more worried about scars; it is more appropriate in patients who want to get surgery done because of odd looking swelling over the neck. TOETVA is safe, feasible, effective, and scar-free alternative to conventional thyroid surgery. We are sharing our first clinical experience in TOETVA in Pakistan with effective outcome in terms of surgical complication and patient satisfaction.

Effect of drainage versus no drainage after thyroid surgery on wound complications, a meta-analysis.

A meta-analysis study was used to assess whether not placing a drain after thyroidectomy reduces postoperative wound complications. A critical review of the comprehensive literature up to May 2023 was conducted using four databases: PubMed, Embase, the Cochrane Library, and the web of science. Fourteen interrelated studies were reviewed after passing the inclusion and exclusion criteria established by the study and assessing the quality of the literature.95% confidence intervals (Cl) and odds ratios (OR) were calculated using fixed effects models. The data were meta-analysed using RevMan 5.3 software. The results showed that the use of drains during thyroid surgery did not have a favourable impact on patients. Intraoperative placement of drains did not reduce postoperative wound haematoma formation in patients, (OR, 0.86; 95% CI, 0.54, 1.36 p = 0.52). However, the incidence of postoperative wound infection was significantly higher in patients with drains used in intraoperative thyroid surgery, (OR, 0.22; 95% CI, 0.10, 0.45 p < 0.0001). As the sample size of the randomised controlled study used for this meta-analysis was limited, it is important to approach the findings with caution when interpreting the results.Conducting additional high-quality research with larger sample sizes is crucial in order to further confirm these results and reduce the likelihood of duplication.
