RESUMO
PURPOSE: Assessing vocal cord mobility is crucial for patients undergoing thyroid surgery. We aimed to evaluate the feasibility and efficacy of surgeon-performed transcutaneous laryngeal ultrasound (TLUS) compared to flexible nasolaryngoscopy. METHOD: From February 2022 to December 2022, we conducted a prospective observational study on patients scheduled for total thyroidectomy at our Institution. All patients underwent TLUS followed by flexible nasolaryngoscopy by a blinded otolaryngologist. Findings were classified as normal or vocal cord movement impairment and then compared. Patients evaluable on TLUS were included in Group A, while those not evaluable were included in Group B, and their features were compared. RESULTS: Group A included 180 patients, while Group B included 21 patients. Male sex (p < 0.001), age (p = 0.034), BMI (p < 0.001), thyroid volume (p = 0.038), and neck circumference (p < 0.001) were associated with Group B. TLUS showed a sensitivity, specificity, positive predictive value, negative predictive value, and accuracy of 100%, 99.4%, 94.4%, 100%, and 99.4%, respectively. Cohen's K value was 0.984. CONCLUSION: TLUS is a valid, easy-to-perform, non-invasive, and painless alternative for evaluating vocal cords in selected patients. It can be used either as a first level exam and as screening tool for selecting cases for flexible nasolaryngoscopy. TLUS should be integrated into routine thyroid ultrasound examination.

Robot-assisted transaxillary thyroidectomy is widely performed in Asian countries, although it is still under discussion in the Western World. However, there have been few studies reporting on the learning curve of robot-assisted transaxillary thyroidectomy. We used the cumulative sum (CUSUM) analysis to assess the learning curve of gasless robot-assisted transaxillary thyroidectomy at a third-level institution in Europe. We included all consecutive patients operated by a single surgeon without previous experience of robotic surgery from February 2012 to January 2023. The primary endpoint of the study was the learning curve extracted from the median operative time using the CUSUM method for the quantitative assessment. Overall, 583 patients were enrolled. The median operative time for thyroid lobectomy and total thyroidectomy was 70 and 90 min, respectively. The CUSUM analysis showed that the learning curve for thyroid lobectomy and total thyroidectomy is 66 and 56 cases, respectively. Moreover, the presence of thyroiditis resulted associated with shorter operative time for total thyroidectomy (p = 0.044), whereas no factors resulted associated with surgical complications. The learning curve for performing robotic transaxillary thyroid lobectomy for a surgeon without previous robotic experience is 66 cases. After that, 56 cases must be performed to acquire proficiency in robotic transaxillary total thyroidectomy. Training programs may reduce the slope of the learning curve.

BACKGROUND: The use of robot-assisted transaxillary thyroidectomy (RATT) has rapidly spread in the last 2 decades, although it is mostly limited to Asian countries. METHOD: We retrospectively enroled all patients with histologic diagnoses of thyroid cancer who underwent RATT at the University Hospital of Pisa from May 2012 to September 2020. RESULTS: The study included 242 patients; 128 (47%) underwent total thyroidectomy and 114 (53%) underwent thyroid lobectomy, among which 28 patients (24.6%) required completion thyroidectomy. Radioactive iodine ablation therapy was required in 90 patients (37%). The complication rate was 5.3%. After a median follow-up of 38 months, an excellent response to therapy was achieved in 107 patients (74%), whereas the response was indeterminate in 12 (8%) and incomplete in 16 (11%). No local or distant relapses or increases in thyroglobulin or antibody levels were documented. CONCLUSIONS: In experienced hands, RATT represents a valid option for the treatment of thyroid cancer in selected cases.
RESUMO
Trans-axillary robot-assisted total thyroidectomy (RATT) is nowadays worldwide accepted but the completeness obtained by RATT is still debated. The Aim of this study was to compare the completeness and safety of RATT with conventional open thyroidectomy (OT). We enrolled patients with nontoxic multinodular goiter, cytologically indeterminate nodules and well differentiated thyroid cancer without local and/or distant metastasis. In all cases the biggest nodule should be < 6 cm. The surgical completeness was evaluated by means of serum thyroglobulin (hs-Tg) and neck ultrasound (nUS) performed three months postoperatively. 100 patients underwent either RATT or OT. The type of surgical procedure was chosen by patients. They were then divided in two subgroups based on benign or malignant histology. There were no significant differences in the postoperatively values of hs-Tg in patients operated with RATT or OT, both in benign and malignant subgroups. The post-operative thyroid remnant volume estimated by nUS was not significantly different between the two groups, both in benign and malignant subgroups. We also analyzed the difference of the volume of the thyroid remnant ipsilateral to the axillary access vs that of the remnant on the contralateral side and there was not significantly difference in both subgroups. RATT was demonstrated to determine a comparable surgical completeness as OT, both in benign and malignant thyroid diseases, with no differences in the prevalence of surgical complications. In our hands the surgical completeness of RATT by a single trans-axillary was satisfying.

In 2016, the American Thyroid Association published a statement on remote-access thyroid surgery claiming that it should be reserved to patients with thyroid nodule ≤ 3 cm, thyroid lobe < 6 cm and without thyroiditis. We retrospectively enrolled all patients who underwent robotic transaxillary thyroidectomy between February 2012 and March 2022. We compared surgical outcomes between patients who presented a thyroid gland with a nodule ≤ 3 cm, thyroid lobe < 6 cm and without thyroiditis (Group A) and patients without these features (Group B). The rate of overall complications resulted comparable (p = 0.399), as well as the operative time (p = 0.477) and the hospital stay (p = 0.305). Moreover, bleeding resulted associated to thyroid nodule > 3 cm (p = 0.015), although all bleedings but one occurred in the remote-access site from the axilla to the neck. In experienced hands, robotic transaxillary thyroidectomy is feasible and safe even in patients with large thyroid nodules or thyroiditis.

Objective: Selpercatinib is a highly selective RET-inhibitor drug, approved for the treatment of RET-altered lung and thyroid cancers. So far, RET-altered medullary thyroid cancer (MTC) patients treated with selpercatinib showed a remarkable objective response rate and safety profile. However, new treatment emerging adverse events (TEAEs) have been recently reported. The aim of this study was to evaluate the prevalence, features, and clinical management of effusions that are one of these TEAEs. Design: Around 10 of 11 patients with advanced MTC enrolled in the LIBRETTO-201 clinical trial at Endocrinology Unit of the Pisa University Hospital were evaluated for the presence and management of effusions. Methods: We retrospectively evaluated MTC patients treated with selpercatinib. The presence of pleural, pericardial, abdominal, and/or pelvic effusions was evaluated by reviewing the computerized tomography scan performed during the study protocol and up to 24 months of observation. Results: All but one MTC patient experienced previous multikinase inhibitors treatment. Three patients already had effusions before starting selpercatinib treatment. New effusions appeared in eight of ten (80%) patients during the treatment. A chylous nature was documented in patients who underwent fluid aspiration. Whenever a dose reduction was performed, a significant positive effect was observed. Conclusions: Chylous effusions are a new TEAE of selpercatinib treatment. They can appear or worsen at any time during the treatment. For cases with asymptomatic and mild effusions, active surveillance may be appropriate and safe. In symptomatic and/or moderate/severe cases, aspiration of the fluid and a dose reduction can improve this AE, strongly supporting a cause-effect correlation with selpercatinib. Significance statement: Effusions, particularly of chylous nature, represent emergent and quite frequent adverse events in the management of patients affected by advanced MTC on treatment with the highly selective inhibitor selpercatinib. In this study, we evaluated, in a series of MTC patients treated with selpercatinib, the prevalence of pleural, pericardial, abdominal, and/or pelvic effusions. Insights into the diagnosis and treatment of the effusions are provided as well as suggestions for clinical management.

Fewer than 100 cases of amiodarone-induced thyrotoxicosis (AIT) managed surgically have been reported worldwide. This study aims to assess the outcome of thyroidectomy under general anesthesia in a relatively large case series. A retrospective analysis of the clinical records of 53 patients who underwent thyroidectomy for AIT between 1995 and 2019 was conducted. There were 48 (90%) males and 5 females with an average age of 63.7 years. Type 1 and 2 AIT were present in 35 (66%) and 18 (34%) of patients, respectively. The mean preoperative ejection fraction (EF) was 45 ± 13%. Salvage surgery was performed in 6 (11%) patients due to decompensating heart failure and/or malignant arrhythmias. 35 (66%) patients underwent urgent surgery due to a predicted late response to medical therapy and/or the need to discontinue it. Elective surgery was performed in the remainder. A considerable improvement in mean EF occurred 12 months post-surgery (44% vs. 49%; p < 0.001). The overall survival rate following thyroidectomy was 96% at 12 months, and 83% at 5 years. No survival differences were observed based on systolic function. Cardiac-specific mortality was 11%, and these patients demonstrated a considerably shorter survival post-surgery compared to those who died of a non-cardiac cause (27 ± 18 vs. 77.5 ± 54 months; p < 0.05). Total thyroidectomy can be safely performed under general anesthesia despite severe cardiac disease. It considerably improves cardiac function and confers a survival advantage. Therefore, it should be considered early in the treatment plan of select cases.

Background: Large thyroid masses, particularly if rapidly growing, are often characterized by compression and infiltration of the vital structures of the neck. Therefore, an early and precise diagnosis, not only of malignancy but also of histotype, is mandatory to set up the right therapy. The aim of this study was to evaluate the diagnostic performance of fine needle aspiration cytology (FNAC) and core needle biopsy (CNB) in this setting. Patients and Methods: We prospectively evaluated 95 patients with large and rapidly growing thyroid masses admitted to the University Hospital of Pisa between April 2014 and January 2020. All patients were submitted to FNAC and CNB in the same session. The ability of both procedures to diagnose the malignancy of the lesions, particularly the histotype, and to obtain sufficient material to perform molecular analysis was evaluated. Results: FNAC obtained adequate tumor sample to reach a diagnosis in 76 of 95 (80%) patients, while a higher percentage was obtained with CNB (92/95, 96.8%). FNAC was able to identify the malignancy of the lesion in 74 of 95 (77.9%) cases, but only in 16 of 74 (21.6%) cases was it able to define the histotype. CNB was able to define the malignancy of the lesion in all but three cases (92/95, 96.8%), and in all specimens, the histotype was identified. Moreover, in all cases, the material extracted from CNB was optimal to perform molecular analysis. No surgery-related complications were experienced with both procedures. Conclusions: CNB is a rapid and safe procedure with higher performance compared to FNAC in identifying the histotype of large and rapidly growing thyroid masses. Moreover, adequate material can be obtained to characterize the molecular profile for the treatment of potentially lethal cancers. In the era of precision medicine, CNB should be introduced in routine clinical practice as a key procedure for an early diagnosis and therapy of these diseases.

In the last decade, robot-assisted trans-axillary thyroidectomy has spread rapidly and has been proven to be a safe and effective procedure. However, several case series have reported new complications that have led to criticism regarding this approach. This study analyzed the incidence of complications in a large cohort of European patients. We enrolled all patients who underwent robot-assisted trans-axillary thyroidectomy from 2012 to 2020 at the University Hospital of Pisa Department of Endocrine Surgery. We analyzed complications and divided them into 2 groups. Group A included conventional complications, such as transient or permanent recurrent laryngeal nerve palsy, transient or permanent hypocalcemia, hemorrhage, and tracheal injury. Group B included unconventional complications, such as brachial plexus palsy, track seeding, seroma, great vessels injury, and skin flap perforation. There were 31 postsurgical complications (5.7%). Group A included 25 complications (4.6%): transient and permanent recurrent laryngeal nerve palsy occurred in 7 patients (1.3%) and in 1 (0.2%), respectively; transient and permanent hypocalcemia occurred in 9 patients (1.7%) and in 1 (0.2%), respectively. Postoperative bleeding occurred in 6 patients (1.1%) and tracheal injury in 1 (0.2%). Group B included 6 complications (1.1%): 1 patient with brachial plexus injury (0.2%), 1 with track seeding (0.2%), and 4 with seroma (0.7%). Robotic trans-axillary thyroidectomy is a safe approach with a risk of postoperative complications comparable to the conventional technique. Almost all complications after a novel introduction are anecdotal. With an accurate patient selection, high-volume institutions with experienced surgeons can perform this technique safely.

BACKGROUND: Robot-assisted transaxillary thyroidectomy is a well-established remote-access thyroid procedure that has been demonstrated to be as safe and effective as its time-honored conventional clamp-and-tie counterpart. However, it has been incriminated for a set of unprecedented complications that surgeons need to be aware of and deal with appropriately. PATIENT FINDINGS: The patient is a young woman who underwent robot-assisted thyroid lobectomy for a sizeable nodule that was reported as benign after fine-needle aspiration cytology. She presented 3 years later with subcutaneous nodules along the surgical track that were found to represent seeding of benign thyroid tissue. This is the first report of benign thyroid tissue seeding after a gasless transaxillary procedure. SUMMARY: Seeding along the surgical track is a potential complication of gasless remote-access thyroid surgery, even in case of benign disease, that surgeons need to be acquainted with. CONCLUSIONS: Surgeons should be aware of the potential for benign seeding after remote-access thyroid procedures. Accordingly, adequate precautions should be taken, patients should be counseled in this regard, and alternative medical strategies to control local seeding of thyroid tissue could be suggested.

BACKGROUND: Cosmetic satisfaction is not only based on the patient's perception of the scar itself but is also related to body image self-evaluation. Cosmetic superiority of Robot-assisted transaxillary thyroidectomy (RATT) over conventional thyroidectomy (CT) has not yet been clearly demonstrated. Aim of our study was to compare body image in patients undergoing CT versus RATT. METHODS: The study included 160 (80 CT and 80 RATT) patients undergoing thyroidectomy between August 2014 and March 2018 at the Endocrine Surgery Department. The inclusion criteria were age 18 to < 60 years, female sex, thyroid volume < 30 mL, and nodule diameter < 5 cm. Scar length, operative time, and complications were analyzed. The body image questionnaire (BIQ) was used 3 months postoperatively. The Student t test was used for statistical analysis. RESULTS: Age was lower in RATT group (38.2 vs 41.4 years) (P < 0.0001). The nodule diameter was larger in RATT group (27.1 vs 23.1 mm) (P = 0.028). Operative time was longer in RATT group (93.7 vs 47.6 min) (P < 0.0001). The scar was longer in RATT group (59.9 vs 37.7 mm) (P < 0.0001). The groups had similar complication rates. BIQ showed that RATT patients answered more favorably to question 2, "Do you feel the operation has damaged your body?" (P = 0.042) and to question 3, "Do you feel less attractive as a result of your treatment?" (P = 0.024). Also self-global satisfaction was better in RATT group (P = 0.019). CONCLUSIONS: In our experience, RATT has a significantly better impact on body image than the conventional approach.

CONTEXT: Patients with amiodarone-induced thyrotoxicosis (AIT) and severely reduced left ventricular ejection fraction (LVEF) have a high mortality rate that may be reduced by total thyroidectomy. Whether in this subset of patients thyroidectomy should be performed early during thyrotoxicosis or later after restoration of euthyroidism has not yet been settled. OBJECTIVES: Mortality rates, including peritreatment mortality and 5-year cardiovascular mortality, and predictors of death, evaluated by Cox regression analysis. METHODS: Retrospective cohort study of 64 consecutive patients with AIT selected for total thyroidectomy from 1997 to 2019. Four groups of patients were identified according to serum thyroid hormone concentrations and LVEF: Group 1 (thyrotoxic, LVEF <40%), Group 2 (thyrotoxic, LVEF ≥40%), Group 3 (euthyroid, LVEF < 40%), Group 4 (euthyroid, LVEF ≥40%). RESULTS: Among patients with low LVEF (Groups 1 and 3), mortality was higher in patients undergoing thyroidectomy after restoration of euthyroidism (Group 3) than in those submitted to surgery when still thyrotoxic (Group 1): peritreatment mortality rates were 40% versus 0%, respectively (P = .048), whereas 5-year cardiovascular mortality rates were 53.3% versus 12.3%, respectively (P = .081). Exposure to thyrotoxicosis was longer in Group 3 than in Group 1 (112 days, interquartile range [IQR] 82.5-140, vs 76 days, IQR 24.8-88.5, P = .021). Survival did not differ in patients with LVEF ≥40% submitted to thyroidectomy irrespective of being thyrotoxic (Group 2) or euthyroid (Group 4): in this setting, peritreatment mortality rates were 6.3% versus 4% (P = .741) and 5-year cardiovascular mortality rates were 12.5% and 20% (P = .685), respectively. Age (hazard ratio [HR] 1.104, P = .029) and duration of exposure to thyrotoxicosis (HR 1.004, P = .039), but not presurgical serum thyroid hormone concentrations (P = .577 for free thyroxine, P = .217 for free triiodothyronine), were independent predictors of death. CONCLUSIONS: A prolonged exposure to thyrotoxicosis resulted in increased mortality in patients with reduced LVEF, which may be reduced by early thyroidectomy.

BACKGROUND: Minimally invasive video-assisted thyroidectomy (MIVAT) was first described in 1999 and it has become a widespread technique performed worldwide. Although initially limited to benign thyroid nodules, MIVAT was progressively adopted for all types of thyroid diseases, while remaining within the selection criteria. It is reported that, in selected cases, MIVAT is comparable to standard open thyroidectomy (SOT) in terms of oncologic radicality, time, costs and complications rate, with the advantage of a better cosmetic result and a lower post-operative pain. METHODS: The authors conducted a retrospective analysis about patients who underwent MIVAT between 1998 and 2019 in the Endocrine Surgery Unit of the University Hospital in Pisa. Indications and contraindications are mentioned and strictly followed. RESULTS: Total thyroidectomy was performed in 1,862 cases (69%) and hemithyroidectomy was performed in 763 cases (28.3%). Conversion occurred in 43 cases (1.6%). In 188 cases (7%) a postoperative transient hypoparathyroidism was reported, whereas definitive hypoparathyroidism was reported in 12 cases (0.4%). Thirty-eight patients (1.4%) suffered from a definitive postoperative recurrent laryngeal nerve palsy. No definitive bilateral recurrent laryngeal nerve palsy occurred. CONCLUSIONS: From our multi-years' experience which spreads over 20 years, we can reaffirm the concept that MIVAT is a safe procedure which is not burdened by an increase complications rate or additional costs. Furthermore, this technique offers advantages in terms of cosmetic results and post-operative pain.
RESUMO
SUMMARY: In elderly patients presenting with a solid thyroid mass, the differential diagnosis between benign and malignant lesion is not always straightforward. We present the case of an 85-year-old woman with fever and an enlarged, firm and painful thyroid mass. Blood exams documented a mild thyrotoxicosis with a moderate inflammatory status. Thyroid scintiscan showed an absent uptake of 131I. Ultrasound and CT scan documented a 3 cm hypoechoic nodule with infiltration of the sternocleidomastoid muscle, very suspicious for neoplastic nature. Fine-needle aspiration and tru-cut biopsy were performed. During biopsy, the lesion was partially drained and a brownish fluid was extracted. The culture resulted positive for Klebsiella pneumoniae whereas the pathological analysis of the specimen was not conclusive due to the presence of an intense inflammatory response. A targeted oral antibiotic therapy was then initiated, obtaining only a partial response thus, in order to achieve a definite diagnosis, a minimally invasive hemithyroidectomy was performed. The pathological analysis documented acute suppurative thyroiditis and the clinical conditions of the patient significantly improved after surgical removal of thyroid abscess. In elderly patients with a solid thyroid mass, although neoplastic origin is quite frequent, acute suppurative thyroiditis should be considered as a differential diagnosis. LEARNING POINTS: A solid and rapidly growing thyroid mass in elderly patients can hide a multifaceted variety of diseases, both benign and malign. A multidisciplinary team (endocrinologist, surgeon, radiologist and pathologist) could be necessary in order to perform a correct differential diagnosis and therapeutic approach. Surgery can be decisive not only to clarify a clinically uncertain diagnosis, but also to rapidly improve the clinical conditions of the patient.
RESUMO
OBJECTIVE: Prophylactic central compartment lymph node dissection (pCCND) results in a higher percentage of surgical-related complications. To date, no evidence of the impact of pCCND on the clinical outcome of papillary thyroid carcinoma (PTC) patients with synchronous ipsilateral cervical lymph node metastases has been reported. METHODS: We evaluated all consecutive patients affected by PTC and synchronous ipsilateral cervical, but without evidence of central compartment, lymph node metastases. We selected 54 consecutive patients (group A) treated by total thyroidectomy, ipsilateral cervical lymph node dissection, and pCCND and 115 patients (group B) matched for sex, age at diagnosis, number and dimension of the metastatic lateral cervical lymph nodes, without pCCND. Clinical outcome after a median of 5 years and surgical-related complications were assessed. RESULTS: The two groups were completely similar in terms of clinical features. Clinical outcomes showed a higher percentage of biochemical and indeterminate but not structural response in group B. Group B required significantly more radioiodine treatments, but no difference was shown in the need to repeat surgery for recurrences. Conversely, the prevalence of permanent hypoparathyroidism was significantly higher in group A (14.8%) than in group B (4.3%). CONCLUSION: In PTC patients with synchronous ipsilateral cervical lymph node metastases, in absence of clinically evident lymph node metastases of the central compartment, performing pCCND does not improve the 5-year outcome in terms of structural disease, despite a greater number of 131I treatments. However, pCCND is severely affected by a higher percentage of permanent hypoparathyroidism, even in the hands of expert surgeons. ABBREVIATIONS: IQR = interquartile range; pCCND = prophylactic central compartment lymph node dissection; PTC = papillary thyroid carcinoma; Tg = thyroglobulin; US = ultrasound.

CONTEXT: It is not known whether total thyroidectomy is more favorable than medical therapy for patients with amiodarone-induced thyrotoxicosis (AIT). OBJECTIVE: To compare total thyroidectomy with medical therapy on survival and cardiac function in AIT patients. METHODS: Observational longitudinal cohort study involving 207 AIT patients that had received total thyroidectomy (surgery group, n = 51) or medical therapy (medical therapy group, n = 156) over a 20-year period. AIT types and left ventricular ejection fraction (LVEF) classes were determined at diagnosis of AIT. Cardiac and thyroid function were reevaluated during the study period. Survival was estimated using the Kaplan-Meier method. RESULTS: Overall mortality and cardiac-specific mortality at 10 and 5 years, respectively, were lower in the surgery group than in the medical therapy group (P = 0.04 and P = 0.01, respectively). The lower mortality rate of the surgery group was due to patients with moderate to severely compromised LVEF (P = 0.005 vs medical therapy group). In contrast, mortality of patients with normal or mildly reduced LVEF did not differ between the 2 groups (P = 0.281 and P = 0.135, respectively). Death of patients with moderate to severe LV systolic dysfunction in the medical therapy group occurred after 82 days (interquartile range, 56-99), a period longer than that necessary to restore euthyroidism in the surgery group (26 days; interquartile range, 15-95; P = 0.038). Risk factors for mortality were age (hazard ratio [HR] = 1.036) and LVEF (HR = 0.964), whereas total thyroidectomy was shown to be a protective factor (HR = 0.210). LVEF increased in both groups after restoration of euthyroidism, above all in the most compromised patients in the surgery group. CONCLUSIONS: Total thyroidectomy could be considered the therapeutic choice for AIT patients with severe systolic dysfunction, whereas it is not superior to medical therapy in those with normal or mildly reduced LVEF.

BACKGROUND: Robot-assisted transaxillary thyroidectomy (RATT) is widely accepted in Asian countries. However, concerns regarding the balance between its real advantages and safety and cost have been raised by North American authorities. In Europe, assessments have been limited by small numbers since now. The purpose here is to report a large European experience with RATT. METHODS: A retrospective analysis was conducted of 257 patients who underwent RATT for nodular disease between February 2012 and September 2016. Data collected included patient demographics, diagnosis, ultrasound-estimated mean thyroid volume and nodule size, type of resection, operative time, postoperative pain and morbidity, and the hospital length of stay. Pain was assessed by visual analog scale score 12 h postoperatively (on the first postoperative day, before discharge). Feasibility, effectiveness, and safety were the outcomes of interest. Follow-up of thyroid carcinoma patients was carried out measuring thyroglobulin levels and ultrasound examination (median follow-up 24 months (6-48 months)). First control after 12 months and successively once a year. RESULTS: There were 253 women and 4 men, with a mean age of 37.3 years. Indications included benign disease in 116, papillary carcinoma in 56, and indeterminate nodule in 85. Mean thyroid volume was 16.8 mL, and nodule size was 25.3 mm. A hemithyroidectomy was performed in 138 patients and total thyroidectomy in 118. The mean operative time was 77.5 min for the former and 99.7 min for the latter. One conversion was required. Complications included transient hypoparathyroidism in 7/118 (total thyroidectomy) patients (5.9%), transient vocal fold palsy in 3/257 (1.1%), 1 delayed tracheal injury (0.4%), and 3 postoperative hematoma (1.1%). Mean visual analog scale score was 1.79, and the mean length of stay was 1.6 days for hemithyroidectomy and 1.9 days for total thyroidectomy. CONCLUSION: RATT is safe and effective and could serve as a viable treatment modality in selected cases.

Post-thyroidectomy neck hematoma represents a major concern for surgeons because it can result in severe and even life-threatening complications. In fact, postoperative hemorrhage may result in airway compression and respiratory distress, and therefore, effective hemostasis is an important goal in thyroid surgery. Postoperative hematoma occurs at a rate of approximately 0.1% to 1.1%. Almost all cases occur in the first 6 h after surgery and can be the result of several surgeon or patient factors. For many years the clamp-and-tie technique has been the most common way to divide the main vascular pedicles of the thyroid gland. Alternatively, bipolar electrocautery has been used for only very small vessels. Other hemostatic systems have been introduced and proved to be potentially very useful in neck surgery and, in particular, for thyroid surgery. This new class of instruments is generally known as "energy devices" because they use different forms of energy, such as advanced bipolar (LigaSureTM Small Jaw Medtronic, Covidien product, Mineapolis, MN, USA) and ultrasound (Harmonic Focus; Ethicon, Johnson and Johnson, Cincinnati, OH, USA), and hybrid devices that join these two technologies (Thunderbeat by Olympus, Japan). Although they all generate a significant elevation of temperature in the tissues, as in any form of energy, the temperatures reached by these instruments are never as high as the standard monopolar electrocautery. For small bleeding very close to critical structures, where energy devices are too dangerous to be used and clamp and tie is not possible, several studies have assessed the use of adjunctive hemostatic agents. In conclusion, all energy devices have been shown to significantly decrease operative times without increasing costs or complications. Adjunctive hemostatic agents have shown equivalent differences when added to standard methods from a clinically significant perspective.
