Wide propagation of new generation of electrosurgical devices such as bipolar vessel sealing systems (eg. Thermostapler® by EMED) enabled seamless closing of blood vessels with a diameter up to 7 mm while maintaining the necessary safety margin, as well as reducing the duration of the operation. We decided to verify these reports in our material. Aim of the study was comparison of thyroid surgery performed with the electrocautery tool – Thermostapler® by EMED with surgery using classic hemostasis technique to evaluate the operative time and complications in the form of bleeding, recurrent laryngeal nerve paralysis, symptoms of hypoparathyroidism, and wound infection. Material and methods. We retrospectively analyzed 256 patients operated in the Department of General and Proctological Surgery Solec Hospital in Warsaw due to inert thyroid goitre. All patients underwent total thyroidectomy. Patients were divided into two groups. The first group consisted of 126 patients operated in 2000, using classic techniques of hemostasis. While the second group consisted of 130 patients operated in 2007-2008 with Thermostapler®. We compared duration of surgery and the incidence of postoperative complications. Results. The operative time was significantly shorter (average 18 minutes) in the second group of patients. We also recorded a statistically significant decrease in the incidence of complications in the group operated with Thermostapler. conclusions. Use of bipolar vessel sealing system in a decisive manner shortens the duration of operation. Use of bipolar vessel sealing system also enables a radical reduction in the incidence of complications rate such as bleeding, recurrent laryngeal nerve paralysis, symptoms of hypoparathyroidism, and wound infection. In the future, similar studies should be performed to assess the real costs resulting from the use Thermostapler®

The aim of the study was to determine postoperative insulin-resistance in patients subject to total thyroidectomy, the prevalence of subjective feelings of hunger immediately before surgery, and the incidence of nausea/ vomiting after surgery in patients prepared for elective operations by means of oral glucose solutions. Material and methods. The study group comprised 115 patients, including 71 patients prepared for surgery by means of oral glucose solutions (12.5% glucose) administered 12 and 3 hours before the procedure, at a dose of 800 and 400 ml. The control group comprised 44 patients prepared for surgery by means of the traditional manner- the last meal was served before 2pm the day before the surgical procedure, while fluids before 10pm. Considering both groups, we evaluated glucose and insulin levels three times, as well as determined the insulin-resistance ratio (HOMA-IR) 24 before, and 12 hours and 7 days after surgery. The incidence of nausea and vomiting after surgery, and the subjective feeling of hunger before surgery were also evaluated. Results. Statistically significant differences considering insulin level and HOMA-IR values were observed during the II and III measurements. The glucose and insulin values, and the HOMA-IR insulinresistance ratio, showed no statistically significant differences during measurement I. No statistically significant glucose level differences were observed during measurements II and III. A significantly greater subjective feeling of hunger before surgery and nausea/vomiting afterwards were observed in the control group. Conclusions. The preparation of patients with oral glucose solutions decreases the incidence of postoperative (thyroidectomy) insulin-resistance, and occurrence of nausea/vomiting during the postoperative period.

was to evaluate the safety of one-day thyroid surgery based on the assessment of the incidence of early postoperative complications. Material and methods. The study comprised 726 patients who underwent total thyroidectomy during the period between January, 2012 and February, 2013. The study considered the three most common thyroidectomy complications. Results. In the group of 726 patients, recurrent laryngeal nerve paralysis was observed in 22 cases, accounting for 3.07% of all patients. Postoperative bleeding was observed in 12 cases (1.65%). In 8 cases, bleeding occurred during the first 8 hours after surgery, while in the remaining four cases- 9, 12, 18, and 26 hours after surgery. The study group was divided into three subgroups, in which the concentrations of calcium and parathyroid hormone, 6 hours and 20 hours after surgery, were determined. In the first group (223 patients), only the parathyroid hormone level was determined. The decreased PTH level was associated with the appearance of tetany symptoms in 15% of cases. Amongst patients in whom the parathyroid hormone level was normal, tetany symptoms were observed in 0.5% of cases. In the second group (256 patients), only the serum calcium level was determined. Amongst patients with normal serum calcium levels, 1% of cases presented with tetany symptoms. In patients where the serum calcium level was reduced, tetany symptoms appeared in 35% of cases. In the third group (247 patients), both serum calcium and parathyroid hormone levels were determined. In the group of patients with normal, both serum calcium and parathyroid hormone levels, tetany symptoms were not observed. Amongst patients with normal serum calcium levels and decreased PTH levels on the day of surgery, tetany symptoms were observed in 25% of cases, while during the first postoperative day-37% of cases. Conclusion. One-day thyroid surgery, due to the appearance of complications cannot be regarded as a completely safe procedure.

Hypocalcemia after thyroidectomy is the most common postoperative complication with reported incidence from 0.5% to even half of the operated patients. Hypoparathyroidism could be a result of careless or inadequate preparation during the surgical procedure. There is a variety of proposed options for prediction of the incidence of hypocalcemia. The most effective of them are the perioperative and intraoperative measurements of PTH level.The aim of the study was to assess the potential correlation between the iPTH levels after the operation and development of hypocalcaemia. The possible prediction value of postoperative iPTH levels was to be evaluated assessed.Material and methods. A prospective study was performed on 100 patients who underwent total thyroidectomy from January 2007 to June 2009. The total calcium level and intact human PTH (iPTH) levels were measured 24 hours before, 1 and 24 hours after the surgery.Results. We have presented a significant correlation between early iPTH measurement and risk of hypocalcaemia. Moreover a significant correlation between the iPTH level 1 hour after operation with the calcium level 24 hours after the operation was demonstrated.Conclusions. Early postoperative assessment of iPTH levels can be used to identify the group of patients at risk of hypocalcaemia after thyroidectomy. Pre-emptive calcium supplementation can lead to avoidance of complications causing prolonged hospital stay and most importantly to prevent severe hypocalcemia.

Objective: The aim of the study was to estimate usability of the piezoelectric knife in larynx surgery. Prove that the piezoelectric staff can be used to do any different shape incision within the larynx cartilages. Material and methods: 35 patients hospitalized in our Department in 2014–2016 were enrolled in our study. 24 patients went vertical partial laryngectomy and 1 patient went horizontal partial laryngectomy because of larynx cancer. 5 patients went partial laryngectomy because of low stage of piriformis recess cancer. Piezoelectric staff was used to do thyroidectomy and resection of thyroid cartilage suspected of carcinomatosis infiltration. The rest 4 patients had done widening of larynx lumen due to larynx stenosis or slenderness. The piezoelectric tool was used to do different incision or resection within the larynx cartilages in case of widening lumen of the larynx. Results: The larynx cartilages, especially thyroid cartilage could be cut in different shapes using piezoelectric tools. The usage of this equipment causes the minimal loss and small destruction of local healthy tissues. Conclusions: The Piezoelectric instrument is useful instrument suit to operate within larynx cartilages. Exchangeable tip available in different shapes enables different resections of cartilages. Using the piezoelectric staff we can remove pathological tissue with minimal local destruction. Our observation shows that larynx operation with a usage of the piezoelectric knife is safe and effective. Current English literature does not describe usage piezoelectric tools in larynx surgery. It is essential to do more observation about that type of operations.

Introduction: Thyroidectomy is a common surgery performed especially in treatment of multinodular goitre. The most common post-thyroidectomy complication is a postoperative hypocalcaemia, and the percentage of postoperative hypoparathyroidism could reach even 50%. Tested group and methods: A forward-looking, randomized testing was done on a group of 113 women being subject to multinodular goitre surgery. In this article, we wish to present an analysis of the results obtained in the control group, focusing on the predicative factors which determine the development of postoperative hypocalcaemia. Obtained results: The rate of postoperative biochemical hypocalcaemia development was significantly higher in the group of patients, where the preoperative calcium concentration was lower than 2,4 mmol/l. In that group, the development of biochemical hypocalcaemia was observed in 93,7% of cases (30 out of 32 patients), in comparison with 65,3% (17 out of 26) in the group of higher preoperative concentration of calcium. The highest risk of occurrence of postoperative hypocalcaemia was borne by the total thyroidectomy, while the lowest one by the subtotal thyroid lobectomy of one lobe only. Conclusions: A higher preoperative concentration of calcium in blood serum is related to the lower rate of occurrence of postoperative biochemical hypocalcaemia. However, no such correlation was revealed in the case of postoperative symptomatic hypocalcaemia. Lack of correlation was determined between the preoperative concentration of TSH and FT4 in blood serum and the rate of occurrence of postoperative hypocalcaemia, both symptomatic and asymptomatic. The performed statistics did not reveal a relation between the postoperative hypocalcaemia and the duration of the surgery, but a significant correlation was stated with the scope of the performed surgery. Revealing a relation between the rate of occurrence of postoperative hypocalcaemia and the experience of the surgeon performing the surgery was not successful.

The most common complications after thyroidectomy are postoperative neck hematoma, recurrent laryngeal nerve injury and hypoparathyroidism [1]. However, iatrogenic cervical esophageal perforation is a very rare repercussion of this procedure. In literature there are a few reported cases concerning this complication. We want to report a case of a patient with severe esophageal injury resulting from thyroidectomy.

Hypoparathyroidism is the most common complication of thyroid surgery. Accurate treatment of this condition requires early diagnosis of patients at risk of hypocalcemia.The aim of the study was to evaluate the predictive value of intraoperative parathyroid hormone assessment in identification of affected subjects.Material and methods. Sixty five subjects participated in the prospective study. They underwent bilateral neck exploration with subtotal or total thyroidectomy. Parathormone (PTH) and calcium levels were assessed prior to surgery, intraoperatively and at different time-points following the operation.Results. In respect of the results, patients were allocated into 3 groups: (A) subjects with asymptomatic course; (B) subjects with perioperative symptomatic hypocalcemia; (C) subjects with prolonged symptomatic hypocalcemia. No differences between these groups were observed in the intraoperative calcium levels. Intraoperative parathormone (ioPTH) level was significantly lower in group C and at value minor of the reference range identified group C subjects with sensitivity and specificity of 100 and 91.5%, respectively. Mean intraoperative PTH level decrease (ΔioPTH) of 22.5% was observed. ΔioPTH rate was significantly higher (81.4%) in group C. This parameter presented sensitivity of 66.7% and specificity of 93.2% in identification of group C patients.Conclusions. Single intraoperative PTH level assessment identifies subjects at risk of postoperative hypoparathyroidism. Intraoperative drop of PTH (ΔioPTH) proves less sensitive. Intraoperative calcium levels cannot be regarded as a predictor of this complication.

Increasing number of surgical subspecialities causes general surgeons have little experience with more complex procedures as total thyroidectomy. The aim of the study was to present the outcome of total thyroidectomy following its implementation in a district hospital where such procedure has not been performed previously. Material and methods. 293 patients were operated on for goiter between 01.10.2008 and 30.09.2011 in the District Hospital in Proszowice by one contracted endocrine surgeon. Hemithyroidectomy was performed in 75 (23.7%) patients and total thyroidectomy in 191 (76.3%) patients for multinodular goiter and only the latter group was subjected for further analysis. Results. There were no bilateral recurrent laryngeal nerve palsy. A unilateral transient recurrent laryngeal nerve palsy occured in 6 patients (3.1%; 1.5% per risk) and postoperative hypocalcemia in 29 (15.7%) patients. 2 (1%) patients required wound revision due to a postoperative bleeding. Postoperative pathology revealed in 12 (6.2%) patients differentiated thyroid cancer. Conclusions. 1. Total thyroidectomy in a district hospital is still a safe way to operate on thyroid for nonmalignant disorders with low number of complications. 2. Total thyroidectomy is a definite surgical treatment in patients diagnosed by postoperative pathology with differentiated thyroid cancer.

The aim of this work was to describe, interpret and highlight the impact of neuroanatomy in the region of the larynx on intraoperative neuromonitoring (IONM) during thyroidectomy. A rich network of anastomoses of the recurrent laryngeal nerve (RLN) and superior laryngeal nerve (SLN) may have impact on the results of thyroidectomy and partial laryngectomy. Intraoperative neuromonitoring is a useful tool in the armamentarium of a head and neck surgeon but it will never replace profound knowledge of surgical anatomy and good surgical technique.

Introduction: Postoperative hypocalcemia is a narrow but significant problem for patients undergoing thyroid and parathyroid surgery. It is the most common complication after thyroidectomy. It is associated with transient or permanent hypoparathyroidism. It could potentially be life-threatening for patients and increases the costs of hospitalization. The aim of the study was to evaluate the results of studies that routinely administrated calcium and/or vitamin D during the postoperative period. Materials and Methods: In this article, a literature review – 15 studies that used routine perioperative calcium (7 studies), vitamin D (2 studies) and calcium with vitamin D (11 studies) supplementation was performed. Supplementation effectiveness in prevention of postoperative hypocalcemia was compared to no prophylaxis in 10 studies. Five studies compared the effect of combined administration (calcium and vitamin D) to calcium alone. The number of papers dealing with this problem is not particularly high. Results: Supplementation significantly decreased the rate of laboratory and symptomatic hypocalcemia. It was also effective in reducing the severity of symptoms. The combination of calcium with vitamin D was the most effective strategy. No hypercalcemia or parathyroid hormone inhibition was observed in the supplemented groups. Routine supplementation was less expensive than performing laboratory tests in the course of treatment of hypocalcemia. Conclusions: The results of analyzed studies showed the clinical and economic advantage of routine perioperative prophylactic supplementation of vitamin D and/or calcium as compared to no prophylaxis. However, the majority of studies showed a significant range of variability in patients’ characteristics. Numerous studies did not evaluate the preoperative 25-hydroxycholecalciferol level – a risk factor for postoperative hypocalcemia. Discussion: The use of routine prophylactic supplementation of calcium and vitamin D in the perioperative period can be useful in everyday clinical practice. Further research is needed to draw clear guidelines regarding prophylactic calcium and vitamin D therapy for patients after thyroidectomy.

Introduction: Voice dysfunction is the most common complication of thyroid surgery. The use of intraoperative neuromonitoring (IONM) is to protect the recurrent laryngeal nerves, the damage of which causes voice dysfunction. Aim: The aim of the study was to evaluate voice quality in patients who underwent complete thyroidectomy operated on with the application of IONM as well as a group of patients operated on with only macroscopic nerve visualization. In the analysis, clinical voice assessment was performed with particular focus on voice efficiency using the Voice Handicap Index (VHI), Vocal Tract Discomfort (VTD) and GRBAS scale. Material and methods: The study group consisted of 205 patients operated on with IONM. The control group consisted of 162 patients subjected to surgery only with macroscopic visualization of recurrent laryngeal nerves, without IONM. During the follow-up period from 2 to 10 years after surgery, checkups were performed. Each patient who came for a checkup was subjected to perceptual voice evaluation with the use of the GRBAS scale, indirect laryngoscopy procedure and voice selfevaluation with two questionnaires (VHI and VTD). Results: The frequency of vocal fold palsy did not differ significantly statistically in the study group and the control group. Both in the study group and in the control group, patients with vocal fold paralysis had statistically significantly higher results in the VHI and VTD questionnaires as well as in the GRBAS study. Conclusion: Patients with recurrent laryngeal nerve injury show significant differences in the scope of voice handicap, both in the voice quality assessment with the use of the GRBAS scale, and self-evaluation questionnaires: VHI and VTD. All voice disorders evaluated with self-assessment are medium voice disability

The aim of the study was to present a retrospective analysis of the experience with completion thyroidectomy for benign thyroid disease in a referral centre.Material and methods. Between October 1999 and December 2007, 2353 thyroid operations were performed for benign diseases. Of these, 113 patients (12 men, 101 women; age: 25-77 years) underwent a reoperation for recurrent goitre (n=107) or recurrent Grave's disease (n=6). A bilateral resection was performed in 33 patients, a unilateral in 80 patients. The mean interval between the initial and the reoperative procedure was 14.5 years.Results. The mean operative time was 78 minutes (range: 20-210) with 68 minutes for unilateral and 96 minutes for bilateral operations. Postoperative complications consisted of transient hypoparathyroidism in 6 patients (5.3%); no patient experienced a permanent hypoparathyroidism. A transient recurrent laryngeal nerve (RLN) palsy occurred in 6 cases (4.1% of "nerves at risk") and a definitive bilateral RLN palsy was registered in a patient with a preoperative unilateral RLN palsy (0.9%). In 4 patients (3.5%) a postoperative bleeding required reoperation. No wound infection was observed. The mean postoperative hospital stay was 2.3 days. Final histology showed a thyroid cancer in 6 patients (5.3%).Conclusion. In experienced hands, reoperative thyroid surgery can be performed safely and with limited morbidity.

Wprowadzenie: Choroby tarczycy, zwłaszcza te, które wymagają leczenia operacyjnego są niezwykle silnym bodźcem emocjonalnym dla chorego. Wywołują one nie tylko dolegliwości lękowe, ale także w przypadku powikłań (zwłaszcza tych długotrwałych) mogą generować nawet zaburzenia depresyjne, bądź w znaczący sposób wpływać na samoocenę pacjenta, a tym samym jego funkcjonowanie na płaszczyźnie społecznej. Cel pracy: Celem pracy było zbadanie jakości życia pacjentów, którzy poddani byli zabiegowi strumektomii tak totalnej jak i subtotalnej. Materiał i metody: Badanie przeprowadzono w grupie 102 pacjentów poddanych operacji w Oddziale Chirurgii Ogólnej Szpitala im. Św. Łukasza w Tarnowie w okresie od grudnia 2018 roku do kwietnia 2019 roku, a także mieszkańców Małopolski, którzy mieli wykonaną tyreodektomię. W badaniach wykorzystano kwestionariusz ThyPROpl, skalę VAS, a także ankietę autorską. Wyniki: Najczęstszymi powikłaniami strumektomii były mrowienie i drętwienie wokół ust oraz kończynach (42,2%). Pacjenci, u których występowały objawy tężyczki posiadali obniżoną percepcję jakości życia i zdrowia, a także jakość życia we wszystkich jego dziedzinach. Ponadto ankietowani posiadali zdegradowaną obniżoną jakość życia w zakresie negatywnego wpływu choroby na życie (62,01) oraz zmęczenia (56,23). Im większe było natężenie bólu, tym niższa była jakość życia pacjentów po strumektomii. Wnioski: Istnieje związek pomiędzy jakością życia badanych po strumektomii a liczbą powikłań, stopniem nasilenia dolegliwości bólowych. Zależność ta jest wprost proporcjonalna.

Introduction: Thyroid diseases, especially those that require surgical treatment, are an extremely strong emotional stimulus for the patient. They evoke not only anxiety disorders, but also in the case of complications (especially those long-lasting) can even generate depressive disorders, or significantly affect the patient’s self-esteem, and thus its functioning at the social level. Aim of the study: The objective of the study was to examine the quality of life of patients who underwent surgical treatment of total and subtotal thyroidectomy. Material and methods: The study was conducted in a group of 102 patients undergoing surgery at the General Surgery Ward of the Hospital. St. Łukasz in Tarnów in the period from December 2018 to April 2019, as well as residents of Małopolska, who had performed thyroidectomy. In research have been used ThyPROpl, VAS Scale, and self-prepared questionnaires. Results: The most common complications of thyroidectomy were tingling and numbness around the mouth and limbs (42.2%). Patients who had symptoms of tetany had a reduced perception of quality of life and health, as well as the quality of life in all its areas. The respondents had a degraded, reduced quality of life in terms of the negative impact of the disease on life (62.01) and fatigue (56.23). The greater the intensity of pain, the lower the quality of life of patients after thyroidectomy. Conclusions: There is the relationship between the quality of life and the number of complications, as well as the severity of pain. This dependence is directly proportional.
