Mini Gastric Bypass (MGB) surgery is an effective surgical method used in the treatment of obesity. It is based on the principle of both reducing the stomach volume and bypassing a portion of the small intestine to achieve weight loss. This surgery is a simpler procedure than the classic Roux-en-Y gastric bypass, but it provides similar results.

In mini gastric bypass surgery, a large portion of the stomach is bypassed and a small, tube-shaped stomach pouch is created. Then, a forward portion of the small intestine is connected to this stomach pouch and the digestive system is partially bypassed. As a result of this procedure, patients feel full with less food and the absorption of nutrients is reduced. Both fewer calories are consumed and some of the calories consumed are excreted without being absorbed by the body.

Since a simpler technique is used, the operation time is short and the risk of complications is lower than some other bariatric surgical methods. Mini gastric bypass surgery is also very effective in treating obesity-related diseases such as type 2 diabetes, hypertension and sleep apnea. However, since vitamin and mineral deficiencies may occur in the post-operative period, lifelong supplementation may be required.

Mini gastric bypass is surgically simpler because it requires less intestinal connection than classic gastric bypass, but lifestyle changes, regular nutrition and doctor follow-up are still of great importance in the post-operative period.

Mini gastric bypass surgery is an effective surgical method used in the treatment of obesity and is usually performed with laparoscopic (closed) surgery. Since this is an operation performed through small incisions in the abdominal area, the recovery period is faster than open surgery and the risk of complications is lower. The surgery is performed under general anesthesia and usually takes 1-2 hours. Here are the stages of mini gastric bypass surgery:

During the surgery, first a large part of the stomach is bypassed and the stomach is turned into a small tube-shaped pouch. This procedure significantly reduces the volume of the stomach, allowing the patient to feel full with much less food. The small stomach pouch created has a capacity of approximately 100-150 ml, which greatly restricts food intake.

In the second stage, a part of the small intestine is bypassed. In this procedure, the upper part of the small intestine is connected to the stomach pouch. Food normally passes from the stomach to the duodenum and from there to the small intestine, but with this surgery it is directed directly to a further section of the small intestine. This allows food to follow a shorter path in the digestive system, thus reducing calorie and nutrient absorption.

This two-stage procedure both restricts food intake and provides effective weight loss by reducing absorption. Since mini gastric bypass requires fewer intestinal connections than classic gastric bypass, it is a simpler and shorter surgical procedure. After the surgery, patients feel full by eating less, and the body eliminates some of the calories taken without absorbing them.

The post-operative period begins with a liquid diet and gradually transitions to solid foods. In addition, long-term vitamin and mineral supplements may be required, because nutrient absorption decreases because a part of the intestines is bypassed.
