Mini Gastric Bypass
Mini gastric bypass is actually known as surgery that combines some features of sleeve gastrectomy. In this process, a long stomach pouch is formed, and then the operation is completed by combining it with the small intestine. Mini gastric bypass, one of the most common surgeries in obesity surgery, is performed on overweight individuals. Because type 2 diabetes patients have to lose weight to prevent high blood pressure and high cholesterol. On the other hand, this procedure can also be performed in patients who have had sleeve gastrectomy or gastric banding before but have not been successful.
Who Can Have Mini Gastric Bypass Surgery?
The suitability for this surgery is decided based on different criteria. Factors such as metabolic diseases, age, condition of the small intestine, reflux or unsuccessful revision surgeries are examined and the operation is decided.
Unsuccessful Operations: Patients who cannot be successful in sleeve gastrectomy can apply for this surgery. Studies have shown that patients who cannot obtain efficiency from restrictive surgeries achieve great results thanks to this procedure.
Small Intestine: The condition of the small intestine is examined before surgery. Small intestines must be free for this procedure. In other words, it is imperative that individuals who have had abdominal surgery before do not have a small intestinal adhesion problem.
Reflux: Mini gastric bypass surgery can be applied successfully in obese individuals with reflux disease.
Metabolic Diseases: The high metabolic efficiency is considered for this surgery, which provides successful results in patients with type 2 diabetes. So it is ideal for patients with obesity or metabolic syndrome.
Age Factor: It is known that mini gastric bypass gives excellent results in patients 13 years and older.

How is Mini Gastric Bypass Done?
This procedure, which reduces stomach volume and also restricts stomach absorption from some of the small intestines, is actually known as obesity surgery. There is no large incision in the closed method, mini gastric bypass procedure. Surgery can be performed with only a few incisions under 1 cm. In addition, a camera and surgical instruments are left into the abdomen through the small holes opened. After a small gastric tube is formed at the entrance of the stomach, it is separated in the other part of the stomach.
The reconstructed stomach is connected to the small intestine at this stage. In this way, foods will pass directly into the intestines. In this part, which is the second stage of the surgery, a small path is made to the stomach.
How are the Small Intestine and Stomach Connected?
In this process, an advanced device called circular stapler is used that connects the intestinal tissue to the stomach tissue. Stapler is a special tool for this process. While cutting the tissue on the one hand, on the other hand, it allows the tissues to join together without any leakage or bleeding by throwing staples around this incision line. These special staples, which are suitable for the closed method, are left in the stomach and intestine adjacent to each other and thus glued together. However, a special gap is created to ensure the transition between them. The name of the connection is also called ‘anastomosis’.
Lose Weight with Mini Gastric Bypass
With this surgery, weight loss can occur in 3 different ways. It is in the form of reducing the stomach volume, hormonal regulation and restriction of absorption.
Restriction of Absorption: During the operation, a part of 200 cm from the beginning of the small intestine is separated from the stomach. This part consists of fluids that provide absorption and digestion. Consequently, absorption is also restricted with the process.
Hormonal Regulation: Most of the stomach will go into passive state after this surgery. In other words, no food passage from the operated area is provided. As a result, the activity of the stomach, which is not stimulated by food, also ends.
Stomach Volume: Thanks to the surgery, the stomach volume will be reduced. The portions will now be reduced with the new stomach. However, the amount of meals consumed is increasing.
What Are The Risks Of Mini Gastric Bypass Surgery?
Mini gastric bypass surgery has some risks. However, these risks will be experienced due to the inadequate diet after the procedure.
These are:
- Nausea and vomiting
• Inability to lose weight
• Getting fat
- Obstruction in the gastrointestinal junction area
• the body being dehydrated
- Dumping syndroms
