Abstract
INTRODUCTION The definition of thyroid goiter remains ambiguous, yet size may impact both malignancy rate and surgical complications' rate. METHODS All patients with thyroid goiter who underwent thyroidectomy between 1/2015-1/2023 were included. Goiter was defined as lobe ≥4 cm. For analysis purpose, goiters measuring 4-8 cm and ≥8 cm were defined as large and extremely large goiters, respectively. For malignancy definition, tumor<1 cm in their largest diameter were excluded from study. Collected data included demographics, cytology, histology and postoperative complication. RESULTS 144 goiters from 111 patients were included. The most common indication for surgery was symptoms (55 %). Compared with large goiter, extremely large goiters demonstrated a trend for tracheal narrowing on pre-operative CT findings (23 % vs. 45 %, p = 0.07 respectively). Overall differentiated thyroid carcinoma (DTC) rate was 17 % (25/144) without statistical difference between groups (p = 0.89). Within goiters with pre-operative benign cytology, the DTC rate was 17 % (7/43). Follicular variant of papillary thyroid cancer was the most common type for both groups. Nodular hyperplasia was significantly associated with extremely large goiters (53 % vs. 73 %, p = 0.03). No significant difference was found in transient hypocalcemia (48 % [15/31] vs. 41 % [5/12], p = 0.6) and other complications' rate between extremely large goiters and the control group. CONCLUSION When discussing management options for patients with goiters, the size of the goiter should not regarded as a higher risk for complications or malignancy, yet the relatively high malignancy rate found should be taken under consideration for resection.

Abstract
BACKGROUND Despite ample of evidence regarding feasibility of simple drainless thyroid surgeries, the evidence of feasibility of such procedures in goiters and central neck dissections remains limited. METHODS Patients undergoing total thyroidectomy (TT) between January 2017 and July 2022 were included. The study included two study groups: drainless TT with central neck dissection (CND) and drainless TT due to goiter, which were compared to two controls: non-goiter drainless TT and drained TT for goiter or with CND. Main outcome was post-operative seroma rate. RESULTS 156 patients met the inclusion criteria for each of the group. No significant differences between groups were found for permanent hypocalcemia, and other complications. Post-operative seroma was found in nine patients (5.8%), all from study groups. No significant differences between groups were found for local infections, aspirations, post-discharge drain insertion. CONCLUSIONS Complex drainless thyroid surgeries, including goiter and CND, are feasible and do not seem to significantly increase rate of post-operative seromas or infections.

Abstract
Radiofrequency ablation (RFA) is a non-surgical treatment for symptomatic, benign thyroid nodules. This treatment works by heating and destroying the nodule tissue, which results in reduction of its size and alleviation of the symptoms involved. RFA is indicated for nodules which are confirmed to be benign on two or more cytological or histological examinations, and which result in clinical symptoms requiring medical treatment. It is associated with good short-term outcomes on one-year follow-up; however, 20%-30% of the nodules regrow after more than three years. Therefore, on the basis of long-term follow-up, management of regrowth is key to patient care following RFA. Regrowth is more likely to occur in nodules that are large in size prior to RFA, and in those with high or increased vascularity. Recently, new techniques such as hydrodissection, artery-first ablation, and venous ablation have been introduced to inhibit regrowth. In addition, appropriate criteria for additional RFA should be applied to manage regrowth and prolong its therapeutic effects. RFA is essentially an alternative to surgery; therefore, the ultimate goal of this procedure is to avoid surgery permanently, rather than to achieve temporary effects.

Abstract
Background This study aimed to investigate the incidence and subtype of thyroid cancer in multinodular goitre (MNG) patients who underwent total thyroidectomy. Methodology A cross-sectional study was conducted at the Khyber Teaching Hospital, screening 207 MNG patients who received complete thyroidectomies between July and December 2022. The senior consultant diagnosed thyroid cancer based on a complete history, physical examination, and laboratory and radiological studies. Ultrasound-guided fine-needle aspiration cytology was performed by a senior consultant radiologist. Bethesda categories for all lesions were recorded. All patients underwent thyroidectomy, and the diagnosis of thyroid cancer was confirmed on histopathology. Results A total of 207 patients were included in the study, with a mean age of 45.55 ± 8.75 years. Out of 207 patients, 24 (11.59%) were diagnosed with thyroid cancer. Out of 62 male patients, 15 (7.25%) had thyroid cancer. Out of 145 female patients, only nine had cancer (p < 0.001). Nine patients with thyroid cancer had a body mass index (BMI) below 18, compared to only five patients with a BMI of more than 30 kg/m2. The difference in age distribution was not significant in our study (p = 0.102). Conclusion In conclusion, our study sheds light on the frequency and potential risk factors associated with thyroid cancer in patients with multinodular goiter. Our findings reveal that papillary thyroid carcinoma is the most commonly observed form of thyroid cancer in this patient population, with around 12 percent of patients diagnosed with thyroid cancer. Notably, our study highlights that male patients and those with a lower BMI may have a greater risk of developing thyroid cancer in the context of multinodular goiter. The findings of this study have important implications for the care and follow-up of MNG patients who receive total thyroidectomy. Further research is needed to investigate the type and prognosis of thyroid cancer in patients with MNG.

Abstract
A potential reduction of goiter volume (GV) of recombinant human thyrotropin (rhTSH) on multinodular goiters (MNG) was previously reported but controversial. Hence we conducted a meta-analysis to estimate the effect of rhTSH-stimulated radioiodine therapy in patients with MNG. PubMed, Cochrane, CNKI, VIP, and Wanfang databases were searched. Mean difference (MD) and odds ratios with 95% confidence intervals (95% CI) were derived by using an inverse variance random-effects model and fixed-effects model, respectively. Six studies (n=237) were involved in the analysis. For 12 months follow up, high dose (>0.1 mg) of rhTSH significantly reduced GV (MD=17.61; 95% CI=12.17 to 23.04; p<0.00001) compared with placebo. No effective pooled results of low dose of rhTSH (<0.1 mg) were applicable for only one study included. For 6 months follow up, the source of heterogeneity was determined by subgroup and sensitivity analysis. High dose group showed vast improvement in GV reduction (MD=16.62; 95% CI=1.34 to 31.90; p=0.03). The reduction of low dose group compared with placebo was inferior to high dose group. No available data were obtained to assess the influence of rhTSH after 36 months follow up for the only included study. Hypothyroidism incidence was higher for rhTSH group. No publication bias was seen. High dose of rhTSH treatment-stimulated radioactive 131I therapy after 6 months and 12 months follow up had a better effect in reducing GV, but with higher incidence of hypothyroidism. Owing to the limited methodological quality, more clinical researches are warranted in the future.

Abstract
PURPOSE The reported incidence of post surgical hypoparathyroidism (HypoPT) varies greatly. Previous research suggests that the definition of HypoPT is not consistent in the literature. We therefore conducted a systematic review to investigate how HypoPT is defined and whether this definition, as well as the selected threshold for hypocalcemia affects the incidence. METHODS Using a predefined search string we identified all articles in PubMed reporting on the incidence of postsurgical HypoPT from 1st January 2010 to January 2017. RESULTS We identified 89 articles that employed 20 different definition of HypoPT. The incidence of HypoPT varied from 0.0% to 20.2%. The definitions were not associated with incidence of HypoPT. Use of prophylactic post-operative calcium supplements, however decreased the risk of HypoPT (p = 0.03), and there was a trend towards a lower risk of HypoPT when using a definition of hypocalcemia below lower limit of the reference range (p = 0.09). CONCLUSION The large number of definitions of HypoPT, as well as the huge variation in incidence point to a problem suggests that the awareness of HypoPT should be raised. Use of prophylactic post-operative calcium supplements may decrease risk of HypoPT. This, however, may be due to reverse causality as awareness of the risk of HypoPT may promote the use of calcium supplementation.

Abstract
BACKGROUND the difference in the risk of thyroid malignancy for patients with multinodular goiter (MNG) and solitary nodular goiter (SNG) remains controversial. Although total thyroidectomy (TT) is the current preferred surgical option for MNG, permanent hypothyroidism in these patients may be a concern. Therefore, we discuss whether nontotal thyroidectomy is a reasonable alternative surgical option. METHODS A retrospective cohort study was performed for 1598 consecutive patients who underwent thyroid surgery for nodular goiter between January 2007 and December 2012. Numerous clinical parameters were collected and analyzed. RESULTS We reviewed 795 patients with MNG and 803 patients with SNG. The prevalence of malignancy on final pathology was significantly higher in the patients with MNG than in the patients with SNG (15.6% vs 10.1%, P = 0.001). However, a multivariate analysis revealed that this difference was insignificant (P = 0.50). Papillary carcinoma was the predominant type in both groups, but papillary microcarcinoma was more frequently found (41.1%) in the patients with MNG. The only multifocal cancers were of the papillary carcinoma histologic type, and the incidence of multifocal papillary carcinoma was significantly higher in the patients with MNG (23.4% vs 7.4%, P = 0.005). Reoperation was not required for the patients who underwent TT for goiter recurrence or incidental carcinoma. The overall rate of recurrence following nontotal thyroidectomy was 12.2%. Among the patients who underwent reoperation for goiter recurrence, 2 (20.0%) were complicated with permanent hypoparathyroidism. Among the patients who underwent a nontotal bilateral thyroidectomy, an average of 56.5% had permanent hypothyroidism. CONCLUSIONS Multinodularity does not increase the risk of thyroid malignancy. However, patients with MNG who develop papillary carcinoma are at an increased risk of cancer multifocality. If a patient can tolerate lifelong thyroid hormone replacement, TT is the preferred surgical option because it helps avoid reoperation and the associated complications. Nontotal bilateral thyroidectomy does not ensure the preservation of thyroid hormone function.

Abstract
BACKGROUND Benign multinodular goiter (BMNG) is the most common endocrine disease requiring surgery. During the last few years a more aggressive approach has become the trend for bilateral BMNG treatment. METHOD Randomized clinical trials of any size that compared bilateral subtotal resection, Dunhill procedure and total thyroidectomy for benign multinodular goiter, published between January 2000 and the end of March 2015, were reviewed. DISCUSSION Total thyroidectomy can be considered the most reliable approach in preventing recurrence. The Dunhill procedure is related to a higher rate of recurrence, but rarely recurrences after Dunhill procedure lead to reoperation. Total thyroidectomy avoid completion thyroidectomy for incidental carcinoma and its related risks. Recurrent laryngeal nerve (RLN) palsy becomes less common as surgical experience increases. Transient and permanent hypoparathyroidism is strictly related to the extent of neck dissection. In the risk-cost analysis we must consider the type of patient candidated to surgery and the impact of the surgical protocol we apply. When thyroid surgery is taken in consideration, specific complication rates of different procedures in each hospital must be analyzed accordingly to patient-specific risk factors and local expertise. CONCLUSION The Dunhill procedure seems to be a good compromise between radicality and prevention of complications, avoiding reoperation for recurrence or completion thyroidectomy for incidental thyroid carcinoma. More follow-up studies and prospective studies are necessary to better evaluate, definitively, whether to prefer total thyroidectomy or Dunhill procedure in case of benign goiter surgery.

Abstract
BACKGROUND About 100,000 thyroid operations are performed in Germany each year. There is a current trend toward more radical surgery for bilateral euthyroid nodular goiter. In recent years, thyroid specialists and specialty guidelines have recommended total thyroidectomy, because it ensures that nodules will not recur and already provides an adequately radical excision in case an incidental carcinoma is found postoperatively on histological study of the specimen. An alternative method is unilateral hemithyroidectomy with contralateral subtotal resection (the Dunhill procedure). METHOD Selective literature review. RESULTS Three randomized controlled trials (RCTs) have compared the longterm outcomes of different surgical methods. In addition, retrospective studies have been published, but their findings must be interpreted with caution because of limitations of method. When all of the data are considered, it appears that radical procedures are often not justified. According to the RCTs, nodules arose during long-term follow-up in 4.7-14% of patients who had undergone subtotal resection; yet, in the two more recent and methodologically more valid RCTs, surgery for recurrent goiter was needed in only 0-0.5% of patients treated with a Dunhill procedure and given adequate hormone supplementation. Most incidental carcinomas are papillary microcarcinomas; this entity is usually adequately treated with hemithyroidectomy. The reported complication rates of total thyroidectomy for permanent hypoparathyroidism in particular range from 0.5% (in specialized centers) to 10% (in a cross-sectional study) and thus seem higher than the corresponding rate for a Dunhill procedure (1-2%). CONCLUSION Total thyroidectomy has significant risks and should only be performed if the indication has been critically assessed. Alternative methods such as the Dunhill procedure are often radical enough with a much lower rate of postoperative hypoparathyroidism; they remain an important option in thyroid surgery. Further RCTs with sufficient long-term follow-up are needed so that the different surgical methods can be reliably compared in detail.

Abstract
PURPOSE OF REVIEW To highlight recent advances in our understanding of the incidence of multinodular goitre (MNG) risk of malignancy, evaluation of patients with MNG, rates and factors predictive of malignancy in MNG, and the choice of surgical procedure for patients with neoplastic MNG. RECENT FINDINGS The incidence of MNG when screened by ultrasound scanning (USS) is between 10 and 20% and when using high resolution USS can be up to 70%. The incidence of occult malignancy within MNG lies between 10 and 35% in surgical series. Younger patients and men have higher rates of malignancy, as do patients with a family history, prior irradiation and those with signs of compressive or invasive disease. Subtotal thyroidectomy has been rejected in favour of either total lobectomy or total thyroidectomy for most patients with MNG. SUMMARY An increasing number of patients with MNG will be encountered in surgical practice. Most patients can be cured with total lobectomy or total thyroidectomy, which minimizes recurrence rates and ensures an oncological approach to patients with incidentally discovered malignancy within MNG.

Abstract
OBJECTIVES The incidence of seroma after thyroidectomy has been reported between 1.3% and 7%. We hypothesised that a flapless thyroidectomy technique would reduce the incidence of seroma. DESIGN Observational case-control study with comparison between retrospective cohort of patients undergoing thyroidectomy with raising of conventional skin flaps and prospective cohort undergoing flapless surgery. SETTING Academic Teaching Hospital. PARTICIPANTS Hundred and seventy-five consecutive patients undergoing thyroidectomy performed by a single surgeon. After the first 85 cases, a change in practice took place, from raising of conventional skin flaps to performing flapless surgery wherever feasible. MAIN OUTCOME MEASURES Occurrence of postoperative seroma, defined as central neck swelling in postoperative period, confirmed by aspiration of serous fluid, and other complications. RESULTS Eight patients who underwent concomitant lateral (jugular) neck dissection were excluded. Among the remaining 167 patients, there were eight seromas (5%). Following the change in practice to flapless surgery, there was a significant reduction in the incidence of seroma (P = 0.025). There was no significant difference in other complications (haematoma; recurrent laryngeal nerve injury; and hypocalcaemia). Among the entire group, the association between seroma and flapless surgery tended towards significance (P = 0.07). Other variables studied, including use of drain and concomitant central compartment neck dissection, had no effect on seroma. CONCLUSION Flapless technique for thyroid surgery may reduce the incidence of postoperative seroma.

Abstract
PURPOSE The aim of this retrospective cohort study was to evaluate the rate of complications in relation to the extent of surgery and some of its consequences. METHODS Between 1972 and 2010, a total of 5,277 consecutive thyroid gland surgeries with 7,383 nerves at risk were performed at our teaching institution. Data of all patients undergoing thyroidectomy were collected prospectively. A total of 2,867 subtotal resections (first study period from 1972 to 1990) were compared with 2,410 extended thyroid resections involving at least a hemithyroidectomy (second period from 1991 to 2010). RESULTS The incidence of permanent recurrent laryngeal nerve palsy in primary operations was significantly higher in the first period compared to the second period (3.6 vs. 0.9 %; p < 0.001). Permanent hypoparathyroidism decreased from 3.2 % in the first period to 0.8 % in the second period (p < 0.001). The incidence of recurrent goiter surgery decreased from 11.1 % in the first period to 8.1 % in the second period (p < 0.001). No significant difference was found in permanent recurrent laryngeal nerve palsy in recurrent disease between the two periods. The socioeconomic benefits of an extended thyroid resection in our patient population are 360 preventable operations, 90 preventable permanent recurrent laryngeal nerve palsies, and 58 preventable cancers. Furthermore, 37 preventable radioiodine ablations and 15 preventable deaths were associated with more radical thyroid resection. CONCLUSION Improvements in surgical technique and change in surgical strategy significantly decreased the prevalence of recurrent laryngeal nerve palsy, hypoparathyroidism, and recurrent disease as well as reduced public health costs associated with recurrent goiter.

Abstract
The main causes of simple diffuse goiter (SDG) and multinodular goiter (MNG) are iodine deficiency, increase in serum thyroid-stimulating hormone (TSH) level, natural goitrogens, smoking, chronic malnutrition, and lack of selenium, iron, and zinc. Increasing evidence suggests that heredity is equally important. Treatment of SDG and MNG still focuses on L-thyroxine-suppressive therapy surgery. Radioiodine alone or preceded by recombinant human TSH stimulation is widely used in Europe and other countries. Each of these therapeutic options has advantages and disadvantages, with acute and long-term side effects.

Improvement in Value of the Process by a change in the management]. ACTA ACUST UNITED AC 2011; 27:161-8. [PMID: 22137200 DOI: 10.1016/j.cali.2011.09.010] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/29/2011] [Revised: 09/30/2011] [Accepted: 09/30/2011] [Indexed: 12/01/2022]
Abstract
OBJECTIVES 1) To present the postoperative morbidity of complete thyroidectomies and the results of their clinical management and costs obtained after surgery. 2) To compare the results obtained for the morbidity and costs in the complete thyroidectomy Process, after the management changes introduced by the Endocrine Surgical Unit (ESU). 3) To define whether these changes improve the Value (benefit/cost ratio) of the Process. MATERIAL AND METHODS Prospective study of cohorts conducted on 529 complete thyroidectomies performed between 1998 and 2011. We present their clinical-pathological characteristics and we compare the clinical and management results obtained after surgery in 2 time periods: 1998-2006 without ESU (group 1, 205 patients) and 2007-2011 with ESU (group 2, 324 patients). The clinical results and the possible benefits are assessed by studying the morbimortality (recurrent lesions, hypocalcaemia [<8 mg/dl], suffocative haematomas and bleeding), and those of management, for the evaluation of the use of operating room time, the average stay and the total cost of the Process. The statistical comparison study was made using Student t test, for the comparison of means and the Chi(2) to compare percentages, accepting P<.05 as significant. RESULTS The global percentage of transient recurrent dysfunctions (TRD) was 6%, and for definitive recurrent paralysis (DRP) it was 1.5%. Hypocalcaemia, at 24 hours was 54.6%, at one month 7%, at six months 6.2% and that of definitive hypoparathyroidism 1.3%. There were 2.8% of suffocative haematomas and 2% adverse effects. The mean surgical time was 98 minutes, and the average stay was 3.66 days. In the comparison of results of the groups, the ESU improved the TRD index by nearly 7 points (10.2 vs. 3.4%, P=.002), that of DRP by 1.5 (2.4 vs. 0.4%; P=.3) until reaching under 1%. The figures on bleeding at 24 hours (53 vs. 44 cc; P=.002) and 48 hours (23 to 17 cc; P<.001), the rate of haematomas by another 6 points (6.3 vs. 0.6%; P<.001), and that of hypocalcaemia at 24 hours (P=.01). The average stay also improved (4.79 vs. 2.94 days; P<.001), the use of operating room time (reduced by 20 minutes/operation; P<.001), the total cost of the Process, decreasing by more than € 2,000/Process (P<.001), and produced a total savings for the hospital in the period of study of € 665,820. CONCLUSIONS 1) The global results (post-operative morbidity) of our total thyroidectomies are within the quality standards. 2) The surgical specialisation and the changes introduced by the ESU improved the clinical results (greater benefit) and those of management, cutting down the average stay and the operating room usage time and decreasing costs. 3) The change in management increased the Value of the Process.
