Laparoscopic Mini Gastric Bypass (MGB) is one of the most commonly performed bariatric surgery and slowly getting popular all over world as obesity surgery. This video demonstrate step by step technique of performing mini gastric bypass surgery by Dr R K Mishra at World Laparoscopy Hospital for a female suffering from Morbid Obesity. Mini Gastric Bypass has Restrictive, Malabsorptive and Hormonal component. Restrictive: A small stomach pouch is created restricting the amount of food you can eat. Malabsorptive: A portion of the small intestine is bypassed. Since the small intestine is responsible for absorbing the calories from the food you eat, bypassing a portion of the small intestine results in fewer calories being absorbed, thus creating additional weight loss. Hormonal: The hormone ghrelin has been nicknamed the “Hunger Hormone” by researchers because of its significant effect on appetite. Gastric Bypass results in a fall in ghrelin levels resulting in a reduced appetite.
