Comparison of Gastric Bypass and Sleeve Gastrectomy in Metabolic and Cardiovascular Indices

Not Applicable

Completed

• Conditions: Morbid Obesity
• Interventions: Procedure: Bariatric surgery

• Registration Number: NCT03851874
• Lead Sponsor: National and Kapodistrian University of Athens

Brief Summary

Morbidly obese patients undergoing either Roux en Y gastric bypass or sleeve gastrectomy were examined preoperatively, 3, 6, and 12 months after surgery. On each occasion, anthropometric data were collected, resting metabolic rate was measured, and the patients underwent a panel of cardiovascular examinations (heart rate variability, baroreflex sensitivity, heart ultrasound). Following that, they consumed a test meal and completed visual analog scales for the subjective assessment of hunger and fullness every 30 minutes for 3 hours. At the same time points, blood samples were collected for the consequent measurement of glucose, insulin, lipids, and gastrointestinal hormones.
