Gastric bypass surgery: How is it performed?

Gastric bypass surgery is performed under general anesthesia. It is performed in two parts.

  • In the first part, the surgeon makes a small pouch in the stomach. The stomach is divided into a large and small portion. This small portion is then stapled to make a small pouch which can hold some amount of food. With a small pouch, the patient feels full quickly and eat less. The is known as the restrictive strategy as the stomach size restricts the amount of food it can hold.
  • In the second part, the small stomach pouch is disconnected from the majority of the stomach and a part of the small intestine. The upper part of the small intestine is stapled by making an incision that divides the upper and lower part. The upper half of the small intestine remains attached to the unused stomach and no longer processes the food. Therefore, the food passes directly from the stomach to the lower half of the intestine, bypassing the upper portion. The surgeon makes sure that the staples do not leak and then the incisions are closed.

Usually, the surgeon conducts the process laparoscopically where a thin tube-like instrument is inserted with a camera on top to get the inside view of the internal organs. The laparoscopic surgery needs small incisions, unlike open surgery where the surgeon makes a large incision.
