Gastric bypass surgery – the Gold standard in bariatric surgery

Category : Surgery

One need not be a medical expert to understand various bariatric surgical procedures. With some understanding of the body system and some basic knowledge about biology, one can learn the basics about the various procedures that are commonly followed. Since obesity is directly linked to food intake, in all kinds of non surgical weight loss programs the focus is on dieting. How much it works is another thing, but that weight loss is related to food intake cannot be denied as this is also factored in the surgical procedures, though in a different way. While dieting is about controlling food intake, the surgical procedures revolve around the modifications of the stomach that slows down hunger and appetite. Each surgical procedure has different techniques of modifying the intestine the most common procedure has been discussed in this post.

Most common gastric surgery

Almost 80 percent bariatric operations in the U.S. are performed by this method which is known as Roux-en-Y gastric bypass surgery.  The name is derived from the fact that the procedure aims at re-routing the food in the stomach with the purpose that the rate of absorption of nutrients and calories is decelerated. As a result, possibilities of weight gain from food intake are completely eradicated. This gives the assurance of long term weight loss that can be sustained without any physical effort.

The procedure explained

The surgical procedure of gastric bypass has two parts.  The first is to create a small pouch and the second is to create a by-pass. The stomach is divided into two parts with the smaller part being used to create a small pouch. The pouch is of the size of a cup of food and is formed by the method of stapling that sews the small part of the stomach.

The second part of the surgery is done to create a by-pass.  The small pouch is detached from the main stomach along with the first part of the duodenum or the small intestine.  Then using the surgical technique named Roux-en-Y the detached parts are connected lower down the small intestine at the area known as the jejunum. Food from the stomach now travels to the jejunum directly bypassing the duodenum. This results in curbing the nutrients and calories that are absorbed by the stomach.

This surgical procedure can be performed by the laparoscopic method where a small hole is made on the body to reach the stomach.  This method is more popular as it ensures speedy recovery of the patient.

Recovery after surgery

People have to stay in hospital for only 2-3 days and the usual recovery tie is 2-3 weeks on an average. However, it depends on the individual as to how much time will actually be required for recovery. Post operative complications can affect about 10 percent patients who might experience digestive problems, bleeding, wound infections and ulcers which are well manageable.

Centers that perform more than a hundred gastric bypass surgeries a year have been found to be affected much less by the risks of complications.
