Gastric Bypass Operations for Bariatric Surgery: Everything You Need to Know
Gastric bypass is a type of bariatric surgery intended to cut down food intake. In gastric bypass operations, a small stomach pouch is created to limit food intake and bypasses are constructed on segments of the small intestine to decrease its ability to absorb nutrients from food. The operation usually takes up to four hours to complete and is performed under general anesthesia.
How is gastric bypass surgery performed? There are currently two techniques for gastric bypass, Roux-en-Y-gastric bypass and biliopancreatic diversion bypass.
Roux-en-Y gastric bypass or RGB
Roux-en Y gastric bypass or RGB is the most commonly employed procedure in the United States. It is less complicated and is least likely to result in nutritional difficulties. A small stomach pouch is created by stapling part of the stomach together and a Y-shaped section in the small intestine is then attached to the pouch. This limits food intake and reduces the ability to absorb calories and nutrients. The pouch is commonly referred to as stomach stapling.
There are two ways to do Roux-en-Y gastric bypass: traditional and laparoscopic. Traditional Roux-en-Y gastric bypass is performed by open surgery with one long incision. Laparoscopic Roux-en-Y gastric bypass uses a thin instrument called laparoscope so that the surgeon can view the inside of the abdomen on a TV monitor. Laparoscopic RGB produces less scarring and lets the patient recover faster.
Biliopancreatic diversion bypass
Biliopancreatic diversion bypass is more extensive than RGB.It is a complicated gastric bypass that aims for a smaller stomach. The procedure removes the lower portion of the stomach and a small pouch is left to connect to the final segment of the small intestine. This reduces the ability of the small intestine to absorb nutrients. Like to Roux-en-Y gastric bypass, biliopancreatic diversion bypass is employed through open surgery and with one long incision. It leaves a permanent scar. It is not as widely used as RGB because of the risk for nutritional deficiencies.
Benefits of Gastric Bypass Surgery
Those who undergo bariatric surgery or weight loss surgery can achieve significant weight loss in two years since a large section of the stomach is bypassed that severely restricts the amount of food that the person can consume. Patients must consume highly nutritious and protein-rich food to meet dietary requirements. Those who undergo the operation will most likely no longer able to tolerate sugars and carbohydrates which contribute to weight loss.
Gastric bypass also has positive effects on common weight-related health problems such as heart disease, hypertension and diabetes. Patients with Type 2 diabetes has been known to improve after the surgery.
