What is Laparoscopic Roux-n-y Gastric Bypass(RnYGB)?
Laparoscopic RnY gastric bypass is a minimally invasive procedure in which a small pouch is created by stapling the stomach along its upper portion. Roux-en-Y gastric bypass is the most common gastric bypass surgery.
Obesity can negatively affect your life and health in a multitude of ways. It is associated with coronary artery disease, high blood pressure, arthritis, diabetes, cancer, depression, sleep apnea, infertility, and other conditions. Weight loss through bariatric surgery considerably reduces the risk of disease and improves obesity-related health conditions as well as other aspects of life.
Laparoscopic gastric bypass is performed under general anaesthesia. Your surgeon makes 4 to 6 small keyhole incisions. A laparoscope (tube with a light and a miniature camera) is inserted through one of the incisions. The camera is fixed to a monitor, which allows your surgeon to get a magnified view of the operating field. Surgical instruments are inserted through the other incisions. A small pouch is created by stapling the upper part of the stomach. The smaller portion of the stomach is then attached directly to the small intestine.
After the surgery, the pouch gets filled with small quantity of food at a time, and the food bypasses a large portion of the lower stomach and the upper portion of the small intestine. As a result, you consume and feel full with less food, and absorb fewer calories, have favorable bile, gut hormones or bacteria changes, thus helping you to lose weight.
Like all surgical procedures, laparoscopic gastric bypass may be associated with certain complications, which include bleeding, infection and blood clots.
The advantages of laparoscopic gastric bypass include:
- Quick initial weight loss and moderately increased total weight loss
- Reduced hospital stay
- Less post-operative pain
- Smaller incisions and less scarring
- Improvement in health conditions associated with obesity
