Background. The need to obtain successful surgical hemostasis had a significant impact on the development of electrosurgery. Innovative technical solutions necessitate the continuous training of surgeons in the use of more modern technologies. The diversity of solutions is also associated with the need to adapt the methods for obtaining hemostasis to the type of operation. Each time, the introduction of new technologies requires a critical evaluation of the results of surgical treatment. The most important measure of quality in thyroid surgery is the presence of chronic complications, such as the recurrent laryngeal nerve palsy and parathyroid insufficiency. Transient disorders also have a significant impact on the patient's comfort and quality of life. The report is preliminary in nature and it requires further investigation. Objectives. The aim of the study was to evaluate the effect of three methods for obtaining hemostasis on the occurrence of hypoparathyroidism, recurrent laryngeal nerve palsy, bleeding and the surgical site infection after thyroid surgery. Material and Methods. A retrospective analysis included patients who underwent thyroidectomy (n = 654). Three methods of hemostasis were used. The first group (n = 339) had blood vessels tied off. In the second (n = 192) bipolar electrocoagulation was used and in the third one (n = 123) bipolar electrocoagulation with integrated cutting mechanism. Results. The transient hypoparathyroidism was found in 1.4% patients in the first group, 8.3% in the second and 27.6% in the third one. Chronic hypoparathyroidism was found in 0.29% in the first group, 0% in the second group and 2.4% in the third group. Significantly statistical differences were found in the incidence of transient hypoparathyroidism. Conclusions. Significant statistical differences were found in incidences of transient hypoparthyroidism in the group where bipolar electrosurgery was used (Adv Clin Exp Med 2015, 24, 2, 275-278).
Effectiveness of hemostatic agents in thyroid surgery for the prevention of postoperative bleeding
Scientific Reports, 2020
Postoperative bleeding remains one of the most frequent, but rarely life-threatening complications in thyroid surgery. Although arterial bleeding is the main cause of postoperative hemorrhage, most often no actively bleeding vessel can be found during revision. Therefore, the coagulation technique for larger vessels may play a minor role, and hemostatic agents could be of higher importance. In this descriptive, retrospective study, data of 279 patients with thyroid surgery (total of 414 thyroid lobectomies) were collected. We reviewed the electronic medical record by analyzing the histological, operative, laboratory and discharge reports in regards to postoperative bleeding. Of the 414 operated thyroid lobes, 2.4% (n = 10) bled. 1.4% (n = 6) needed reoperation while the other 1.0% (n = 4) could be treated conservatively. Hemostatic patches were applied 286 (69.1%) times. Of the 128 (30.9%) patch-free operated sides, 4.7% (n = 6) suffered postoperative bleeding. Tachosil® alone was u...
Hemostatic agent use in thyroid surgery: a meta-analysis
Gland Surgery
Background: The use of hemostatic agents in thyroid surgery has been widely reported in the literature. The aim of this study is to assess the safety and efficacy of hemostatic agents in comparison to conventional techniques for hemostasis by meta-analysis of the current literature. Methods: Articles were identified from PubMed and EMBASE using the following keyword searches: "hemostatic agent and thyroid surgery" and "hemostatic agent and thyroidectomy". Outcomes included total operative time, estimated blood loss, length of hospital stay, and intraoperative and postoperative complications. Data were extracted following review of appropriate studies by two independent authors and outcome differences were calculated using analysis of variance and the Bonferroni method. Results: Thirty-four publications were identified and 10 studies met our inclusion criteria, totaling 941 patients, 519 (55.1%) of which received a hemostatic agent during thyroid surgery. Of these patients who had hemostatic agents, 369 (71%) received a hemostatic gel and 150 (29%) received an oxidized cellulose patch. Outcome measures in each of these groups were compared with the patients receiving only conventional methods of hemostasis. The risk of hematoma formation in the hemostatic gel group was comparable to conventional hemostatic methods (95% CI: 0.33, 2.59). This was also true when comparing conventional hemostasis to the patch (95% CI: 0.64, 15.24). No difference in the risk for seroma formation was found between the conventional and hemostatic gel groups (95% CI: 0.26, 3.95). Drain output was significantly less in the gel group 40.75±35.6 mL compared to 66.26±31.2 mL in the conventional group (95% CI: −23.422, −7.460). Patients who received hemostatic agents had shorter hospital stays when compared to the conventional group (95% CI: −1.057, −0.203). Conclusions: Our meta-analysis suggests that the use of a hemostatic agent in thyroid surgery yields minimal advantages for the management of perioperative bleeding risk.
Risk of Complications in Patients Undergoing Complete Thyroidectomy. A Retrospective Study
Introduction: The main aim of this study was to determine the influence of surgery on postoperative complications in patients undergoing total thyroidectomy. Methods: Patients diagnosed with goiter and undergoing total thyroidectomy for more than ten years were retrospectively enrolled, and the main study outcomes were postoperative complications. Statistical analysis was done by chi-square and t-test with a p-value <0.05 as significant. Results: A total of 116 patients with goiter were identified (mean age, 45.3 ± 8.75 years, with minimum and maximum age of 23 to 69). The most affected age with goiter resulted in 41-50 years old with 41.4% (95% CI, 37.4 to 45.8%). The majority of patients with goiter were women (85.3%), with a mean age of 47 years. After the thyroid surgery, male patients had significantly higher rates of hospital readmission than females with a risk ratio [RR] of 1.05; 95% CI [0.67–1.52], p-value = 0.02. Either hemorrhage/hematoma occurred in 4.7% and cardiopulmonary and thromboembolic events in 3.1% of the patients undergoing total thyroidectomy. In addition, either hypoparathyroidism was observed in 3.1% and temporary recurrent laryngeal nerve palsy (RLN) in 1.56%. Conclusion: The current study demonstrates that total thyroidectomy is associated with an increased rate of hemorrhagic complications. RLN palsies and hypoparathyroidism are less observed. Male patients undergoing thyroidectomy have higher rates of readmission and ICU admission. Furthermore, male patients revealed higher rates of hemorrhage and wound infection, while hypoparathyroidism or temporary recurrent laryngeal nerve palsy was more frequent among female patients.

BACKGROUND Postoperative hypocalcaemia is a common complication after total thyroidectomy but most often it is transient. Although these are mostly amenable to calcium and vitamin D supplementation, symptomatic patients sometimes need prolonged hospitalization following thyroid surgery, leading to increased healthcare costs. In the present study, we tried to find out factors which can predict the occurrence of post-operative hypocalcaemia & hypoparathyroidism in total thyroidectomy patients, facilitating their early detection and institution of definitive management in time, preventing emergency admissions & catastrophes. METHODS A prospective observational study was carried out in the Department of ENT & Head-Neck Surgery of a tertiary care govt. hospital in eastern India. Patients who underwent total thyroidectomy for multinodular goitre (MNG) and adenomatoid goitre (AG) or total/completion thyroidectomy for well differentiated thyroid carcinomas (WDTC), in the age group of 20-55 years were included in our study. We recorded the following parameters: Age, gender distribution of cases, type of operation, pre-operative Fine Needle Aspiration Cytology (FNAC) status, size of thyroid nodule operated (based on pre-operative ultrasonographic study), number of parathyroid glands preserved during operation, pre-operative vitamin D levels, post-operative serum calcium levels at 6 hours & 12 hours (positive i.e. increasing slope & non-positive i.e. decreasing/non-changing slope), early post-operative serum iPTH levels (at 6 hours), development of symptomatic hypocalcaemia-transient or permanent. RESULTS In the present study we measured serum calcium level 6 hours & 12 hours post-operatively. It has been found that patients with serum calcium levels on positive slope have lesser chances of occurrence of symptomatic hypocalcaemia & permanent hypocalcaemia than those on non-positive slope. We found that patients having serum iPTH level between 15-65 pg/ml showed lesser propensity to develop hypocalcaemia in comparison with those with serum iPTH level <15 pg/ml. In our study, it has been found that all the 3 cases who developed permanent hypocalcaemia were suffering from vitamin D deficiency; whereas, patients with normal vitamin D levels posed lesser risk of developing significant hypocalcaemia. In our observation, patients with only two parathyroid glands identified per-operatively have more chances of developing hypocalcaemia & those in whom all four parathyroid glands were preserved, very low risk of hypocalcaemia is associated. Furthermore, preservation of functional parathyroid gland with intact blood supply is found to be of immense importance than mere identification of the glands. In our series, it has been noted that with increase in the size of thyroid nodule, chances of hypocalcaemia increases. Patients undergoing complete thyroidectomy for histopathological report of WDTC in a previously benign (based on pre-operative FNAC) thyroid nodule, increased chances of development of post-operative hypocalcaemia. CONCLUSIONS Development of hypocalcaemia post thyroidectomy is multifactorial, some of which are predictable & some of which are correctable, either pre or post operatively, in order to reduce the chances of development of hypocalcaemia. Assessment of these factors helps in early identification of patients who are prone to develop significant hypocalcaemia in combination with the peroperative factors & ultimately helps in early institution of definitive replacement therapy, preventing unnecessary emergency readmission & helps in reducing the duration of hospital stay by facilitating early discharge, thus overall reducing burden on the healthcare system.
Prevention and management of bleeding in thyroid surgery
Gland surgery, 2017
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...
Risk factors for postoperative bleeding after thyroid surgery
British Journal of Surgery, 2012
Background Postoperative bleeding after thyroid surgery is a feared and life-threatening complication. The aim of the study was to identify risk factors for postoperative bleeding, with special emphasis on the impact of the individual surgeon and the time to diagnosis of the complication. Methods Data on consecutive thyroid operations were collected prospectively in a database over 30 years and analysed retrospectively for potential risk factors for postoperative bleeding. Results There were 30 142 operations and postoperative bleeding occurred in 519 patients (1·7 per cent). Risk factors identified were older age (odds ratio (OR) 1·03 per year), male sex (OR 1·64), extent of resection (OR up to 1·41), bilateral procedure (OR 1·99) and operation for recurrent disease (OR 1·54). The risk of complications among individual surgeons differed by up to sevenfold. Postoperative bleeding occurred in 336 (80·6 per cent) of 417 patients within the first 6 h after surgery. Postoperative bleedi...
