Purpose: This study evaluates the knowledge of surgical residents in a tertiary hospital regarding the operational principles, potential complications, and mechanisms of energy devices used in surgery. Methods: A 16-question test was developed using educational materials in the “Fundamental Use of Surgical Energy (FUSE)” program, prepared by the Society of American Gastrointestinal and Endoscopic Surgeons (SAGES) for educational purposes, and from literature on energy devices. The test was shared online with surgical branch residents via Google Forms, and they were asked to complete it. Participants were given one week to complete the test and return the results online. Results: A total of 108 residents voluntarily participated in the study. The average number of correct answers was 6.5 out of 16. There was no significant difference between the correct answer rates for surgical branches. However, an increase in surgical seniority was associated with a higher number of correct answers (P < 0.001). Conclusion Theoretical education about energy devices in surgical training needs to be improved. Surgical residents reported insufficient knowledge regarding the devices’ operational principles and complication mechanisms.

PURPOSE: To evaluate the diagnostic accuracy of routine calcitonin measurement in patients with nodular thyroid disease. METHODS: Consecutive patients with nodular thyroid disease (n = 640) were studied. Serum calcitonin levels were measured under basal conditions, and when basal values were between 10–100 pg/mL, testing was repeated after pentagastrin (PG) stimulation. Patients with previously diagnosed or familial medullary thyroid cancer (MTC) were excluded. Patients were operated on when basal or stimulated calcitonin >100 pg/mL or when other surgical indications were present. RESULTS: Four cases of MTC were identified. MTC was diagnosed in 75% of patients with basal calcitonin >100 pg/mL. One out of 11 patients with basal calcitonin between 10–100 pg/mL was diagnosed with MTC. PG stimulation resulted in elevation in 4 cases, where 1 case was diagnosed with MTC. Positive predictive value for basal calcitonin levels in the preoperative diagnosis of MTC was 5% for values between 10–100 pg/mL and 100% for values >100 pg/mL. Possible reasons for false positivity were papillary thyroid cancer in 17%, renal insufficiency in 8.3%, Hashimoto thyroiditis in 17% and β-blocker use in 33%. Positive predictive value for the PG test (>100 pg/mL) was 25% in the entire series. The cost of adding calcitonin measurement (±PG stimulation) to the preoperative work-up, resulted in €912.68 per MTC patient to detect the disease. CONCLUSION: Basal calcitonin measurement together with PG stimulation in cases of basal calcitonin >10 pg/mL detects MTC in 0.62% of patients with nodular thyroid disease.

Purpose: Visible scars on the neck caused by thyroid surgery give rise to significant aesthetic, functional, and psychosocial problems. The objective of this study is to comparatively investigate the public perception of neck scar cosmesis in Turkish and South Korean populations. Methods: This survey was prepared to collect participants’ demographic and socioeconomic data and determine their perception of scar cosmesis on the neck and consisted of 15 questions. One thousand thirty-nine individuals who did not undergo thyroid surgery completed the survey. The P-values of <0.05 were deemed to indicate statistical significance. Results: There were 1,039 respondents, of whom 525 (50.5%) were Turkish and 514 (49.5%) were South Korean. South Korean respondents stated that they would be significantly more uncomfortable with the thought of having a scar due to thyroid surgery, compared to the Turkish respondents (P < 0.001). The South Korean respondents stated that they would be significantly more concerned about the scar’s length, thickness, and darkening color, compared to the Turkish respondents (P < 0.001 for all cases). Conclusion Patients’ expectations, which are affected by various sociodemographic factors and cultural characteristics, are as important as the medical condition when deciding on the type of thyroid surgery. The study findings clearly indicated that the South Korean population would be significantly more uncomfortable with having a scar on the neck, compared to the Turkish population. Therefore, in selected cases, a scarless thyroidectomy approach, such as transoral endoscopic thyroidectomy, vestibular approach may be preferable for societies like South Korea.
