Brief Summary
Literature data clearly demonstrate that treatment of obese patients is very expensive, long and achieve weight loss may not be permanent, and regardless of whether the treatment dominated diet therapy, physical activity, or pharmacotherapy. Experience of the last decade has shown that after surgical interventional treatment of obesity occurs not only long-term (10 years and over) weight loss of 35-40%, but also an important endocrine changes. In recent years, it was discovered a number of signaling molecules produced by adipose tissue, whose physiological significance beyond the general metabolic aspects organism. The fat is therefore currently understood as an endocrine organ whose hormones modulate the function of many systems, including the skeleton. These hormones include the adipokines that modulate metabolism skeleton as at tissue level (Leptin, Adiponectin) and indirectly - by activation of neurohumoral hypothalamic centers - Leptin. Studying endocrine interactions between adipose tissue and bone is a highly topical issue. This mutual communication is a homeostatic feedback system in which adipokines and molecules secreted by osteoblasts and osteoclasts are the connecting link active axes fat - bone tissue. However, the mechanisms of this axis remain largely unknown.

Outcome Measures
Primary Outcomes (5)
Changes in serum levels of adipose tissue hormones
To analyze the dynamics of changes in serum levels of adipose tissue hormones (Leptin, Adiponectin) in adults after bariatric treatment of malignant obesity (BMI\> 35). Points of measurements: before the planned intervention and then in intervals of 3, 6, 12, and 18 months after procedure.
18 months
Changes in serum levels of lipids
To analyze the dynamics of changes in serum levels of lipids in adults after bariatric treatment of malignant obesity (BMI\> 35). In the study, serum concentrations of the following lipids will be measured: tricylglycerols, total cholesterol, high-density lipoprotein, low-density lipoprotein cholesterol, Apo D and Apo E. The measurements will be performed before the planned intervention and then in intervals at 3, 6, 12, and 18 months after the procedure. The results will be presented in respective units (mmol/L, mg/dL, etc.).
18 months
Changes in serum levels of osteomarkers
To analyze the dynamics of changes in serum levels of usual panel of osteomarkers in adults after bariatric treatment of malignant obesity (BMI\> 35). The following serum levels markers of bone resorption and formation will be assessed: CTx, P1NP, ALP, RANKL, FGF 23, Osteocalcin, Osteopontin and vitamin D2 and D3. The measurements will be performed before the planned intervention and then in intervals at 3, 6, 12, and 18 months after the procedure. The results will be presented in respective units (mmol/L, mg/dL, etc.).
18 months
IWQOL Questionnaire evaluation
Evaluation of effects of different types of bariatric interventions on quality of life will be performed by using the IWQOL questionnaire. Improvement from baseline quality of life as measured by standardized IWQOL patient questionnaire (http://www.qualityoflifeconsulting.com/iwqol-lite.html) intended to measure the patient health status.
18 months
SF-36 Questionnaire evaluation
Evaluation of effects of different types of bariatric interventions on quality of life will be performed using the SF-36 questionnaire. Improvement from baseline quality of life as measured by standardized SF-36 patient questionnaire intended to measure the patient health status.
18 months

Study Arms (3)
Laparoscopic sleeve gastrectomy
ACTIVE COMPARATORPatients undergoing bariatric surgery procedure of laparoscopic sleeve gastrectomy.
Laparoscopic gastric plication
ACTIVE COMPARATORPatients undergoing bariatric surgery procedure of laparoscopic gastric plication.
Intragastric balloon
ACTIVE COMPARATORPatients undergoing bariatric surgery procedure with intragastric balloon implantation.
Interventions
Sleeve gastrectomy involves removing most of the stomach, limiting the amount of food the patient can eat.
Laparoscopic gastric plication involves sewing one or more large folds in the stomach. During the laparoscopic gastric plication, the stomach volume is reduced about 70%, which makes the stomach able to hold less and helps the patient eat less.
The introduction of the balloon is non-invasive as it is inserted endoscopically (down the oesophagus). The balloon is then filled inside the stomach with a dyed physiological solution, which reduces the volume of the stomach.
Intragastric balloons (End-Ball, Medsil) will be implanted in the patients with morbid obesity.
