Stomach Bypass Surgery

Stomach Bypass Surgery

Unlike sleeve gastrectomy, the bariatric surgery method, which both restricts food intake and changes bowel functions and reduces nutrient absorption, is called “gastric bypass” or “Roux-en-Y”.

During the gastric bypass operation, a small pouch is first created in the stomach, and then the pouch created is connected directly to the small intestine. After gastric bypass surgery, which is completed in two stages, when patients eat, the food they swallow first goes to the small stomach in the form of a pouch and then proceeds directly to the small intestine.

Surgery Summary

Gastric bypass surgery, which can be performed successfully with both open and closed techniques and frequently performed with closed technique in recent years, consists of two stages. During the gastric bypass performed with special surgical instruments through the holes opened in the abdominal area, a new stomach is first created in the form of a small pocket. The small stomach formed and the large part of the stomach is separated and the majority of the stomach is deactivated before it is removed from the body. In the second stage of the operation, the small intestine is shortened.

The small intestine, shortened by an average of 50-75 cm, is attached to the new stomach formed adjacent to the esophagus. The cut part of the intestine is reunited with the intestine approximately 70 cm further. After Gastric Bypass surgery, which is completed in 1 – 2 hours, the food intake of the patients is restricted and nutrient absorption is reduced. Unlike sleeve gastrectomy, parts of the stomach and intestines that are cut during gastric bypass surgery are not removed from the body.

Advantages of Stomach Bypass Surgery

  • Thanks to gastric bypass surgery, the stomach is reduced and food intake is restricted and nutrient absorption (especially fat and sugar) is reduced because the small intestine is cut. Thus, the weight loss process is accelerated.
  • Since the stomach is reduced after gastric bypass, patients begin to feel full more quickly despite eating less.
  • The risk of joint disorders, sleep apnea, high blood pressure, high cholesterol, and heart diseases that may occur due to overweight, especially diabetes, is reduced.
  • Since the point where the new stomach is connected to the intestine during gastric bypass is narrower than normal, patients may experience a feeling of satiety for a longer period of time.
