Purpose: Thyroid hormone is an important hormone in maintaining metabolism and homeostasis in the body. There exists a common perception among patients that thyroid surgery will cause weight gain. Prevention of any undesired weight gain could be important for the maintenance of well-being in most patients. Our study compares changes in body mass index (BMI) and weight after total thyroidectomy or lobectomy in thyroid cancer patients. Methods: A total of 967 patients with differentiated thyroid carcinoma were enrolled in the study, from March 2011 to July 2016 at Chung-Ang University Hospital. Exclusion criteria were less than lobectomy, modified radical neck dissection, recurred operation, and combined operation for other causes. Primary endpoints were change in body weight and BMI at 2 years after surgery. A subgroup analysis was performed for patients with significant weight change. Results: There were no differences between both groups in BMI after 2 years of thyroid operation. Thyroid stimulating hormone (TSH) levels were not significantly different. Fifteen percent of patients showed significant change in body weight after 2 years of operation. The subgroup analysis of these patients showed no significant differences in gender, age, or extent of operation between those who had gained weight compared to those who had lost weight. There were also no differences in postoperative TSH levels, levothyroxine supplementation, or radioactive iodine treatment. Conclusion There was a minimal postoperative increase in mean BMI over the years in patients undergoing thyroidectomy for differentiated thyroid cancer. However, weight change did not differ in those undergoing thyroid lobectomy or total thyroidectomy.

PURPOSE: The purpose of this study was to determine the extent of safety of medial dissection of the thyroid gland along the trachea. Medial to lateral dissection of the thyroid gland along the trachea after early division of the isthmus has been known to be a useful technique in thyroid surgery, especially for difficult cases, but the risk of injury of the recurrent laryngeal nerve (RLN) has constrained thyroid surgeons from utilizing this technique to its full extent. METHODS: Distances of the laryngeal entry point (LEP) of 134 RLNs of 71 patients from the midline of the trachea, and some other anatomical distances, were measured intraoperatively. The relationships of the intraoperatively measured data with circumferences of the cartilaginous portion of the trachea (CCT) around LEP measured preoperatively by CT scan were evaluated. RESULTS: LEP was always located within 2 mm vertically from the horizontally extended line of the inferior border of the cricoid cartilage and was the closest point from the midline in the whole course of the RLN. The distance between LEP and the midline was very closely correlated with CCT measured on preoperative CT scan, and it can be accurately calculated with a regression equation; Distance between LEP and the midline = (0.42 × CCT) + (1.2 × sex) + 3.2 (mm) (sex: female=0, male=1; R2 = 0.85). CONCLUSION: Early division of the isthmus and dissecting the thyroid off the trachea to the calculated extent is a safe and effective procedure.

BACKGROUND/AIMS: Although cardiovascular (CV) risk factors are well established, some patients experience acute myocardial infarction (AMI) even without any risk factors. METHODS: We analyzed total 11,390 patients (63.6 ± 12.6 years old, 8,401 males) with AMI enrolled in Korea Acute Myocardial Infarction Registry-National Institute of Health from November, 2011 to December, 2015. Patients were divided into two groups according to the presence of any CV risk factors (group I, without risk factors, n = 1,420 [12.5%]; group II, with risk factors, n = 9,970 [87.5%]). In-hospital outcomes were defined as in-hospital mortality and complications. One-year clinical outcomes were defined as the composite of major adverse cardiac events (MACE). RESULTS: Group I was older (67.3 ± 11.6 years old vs. 63.0 ± 12.7 years old, p < 0.001) and had higher prevalence of female gender (36.2% vs. 24.8%, p < 0.001) than the group II. Group I experienced less previous history of angina pectoris (7.0% vs. 9.4%, p = 0.003) and the previous history of cerebrovascular accidents (3.4% vs. 6.9%, p < 0.001). In-hospital mortality (2.6% vs. 3.0%, p = 0.450) and complications (20.6% vs. 20.0%, p = 0.647) were no differences between the groups. And 1 year clinical outcomes (5.7% vs. 5.1%, p = 0.337) were no differences between the groups. In multivariate logistic regression analysis, serum creatinine level (hazard ratio, 1.35; 95% confidence interval, 1.05 to 1.75; p = 0.021) were independent predictors of 1 year MACE in patients without any CV risk factors. CONCLUSIONS Elderly female patients were prone to develop AMI even without any modifiable CV risk factors. We suggest that more intensive care is needed in AMI patients without any CV risk factors who have high serum creatinine levels.
