Ethanol ablation of thyroid cysts in the young with a focus on efficacy and quality of life

Objective

Ultrasound-guided percutaneous ethanol injection therapy (US-PEIT) is used in patients with recurrent symptomatic thyroid cysts as a credible alternative to surgery. Young patients commonly do not wish to undergo surgery and prefer ethanol ablation, if available. The effect of this approach on quality of life is an essential factor in deciding on the treatment options, especially in the young with a long life expectancy and no comorbidity.

Methods

We performed US-PEIT in a cohort of young patients, 15-30 years, from 2015 to 2020. The patients' general quality of life (QoL), self-reported compression symptoms and neck appearance were evaluated.

Results

The cohort comprised 59 patients with 63 cysts, more women than men, with a mean age of 23.8 years. About 1.5 mL of injected alcohol were needed to reach a 90.7% mean cyst volume reduction ratio in 12 months. The method did not fail in any of the patients; a single US-PEIT session was undertaken in 46% of them. The procedure significantly improved each of the patients' symptoms with a significant total score difference (P < 0.001). The total symptom score correlated with the initial cyst volume (P = 0.002; r = 0.395). The mean QoL score by SF-36 6 months after the last US-PEIT was significantly different for physical component summary 56.5 (P < 0.001) but not different for mental component summary 47.7 (P = 0.125), compared to age-corresponding norms.

Conclusions

US-PEIT is a safe and effective method for the young, leading to improvements in cosmetic and subjective complaints, and should also be considered as first-line treatment in the young.

Effect of Laparoscopic Sleeve Gastrectomy on Serum Adipokine Levels

Bariatric procedures are considered to be the most effective treatment options for obesity. One of them is laparoscopic sleeve gastrectomy (LSG), which is nowadays very popular and widely used. LSG leads to weight loss and metabolic improvement and also changes adipokine levels, although it is just a restrictive operation. We describe changes in pro-inflammatory (leptin, resistin, visfatin and chemerin) and anti-inflammatory adipokines (adiponectin, omentin), with adiponectin and leptin being most studied. Their levels are markedly changed after LSG and this may partially explain the weight loss seen after LSG. Adipokines are closely connected to insulin resistance and chronic inflammation both being positively influenced after LSG. Leptin regulates amount of body fat, appetite, thermogenesis and metabolic rate and its levels are positively correlated with both weight and BMI changes after operation. Resistin influences insulin sensitivity, modulates body cholesterol trafficking and its changes after operation correlate with BMI, waist circumference, fat mass, LDL cholesterol and C-reactive protein. Chemerin, an important component of immune system, decreases after bariatric surgery and its levels correlate with BMI, triglyceride levels, and blood glucose. On the other hand, pro-inflammatory adipokine adiponectin, which influences fatty acid oxidation, browning of fat tissue and energy metabolism, is declining after LSG. This decline explains improvement of glucose status after bariatric surgery in patients with diabetes and is correlated with BMI loss, waist circumference and LDL cholesterol level. Effect of LSG goes beyond calory restriction and the changes of adipokines have a great impact on health status of the bariatric patients.
