What is Mini Gastric Bypass Surgery?

Obesity is an increasingly obese disease that is constantly becoming widespread today and becoming a necessity. Obesity, which cannot be prevented by diet and exercise and has reached advanced dimensions, must be treated with surgical methods. Mini-gastric bypass surgery is one of the surgical methods used in the world.

Mini gastric bypass surgery is one of the most commonly performed operations in obesity surgery. The reason for this can be said to be the easiest, shortest time, shortest and most economical gastric bypass operation. After mini gastric bypass operation, desired weight loss is experienced. In addition, diabetes (type 2 diabetes), which is triggered or caused by overweight, is a treatment for diseases such as high cholesterol and blood pressure.

The general objectives of all obesity surgeries are to reduce stomach volume and to provide a more comfortable feeling of satiety. Gasatric bypass surgery is performed within the same framework. The operations performed by laparoscopy (closed) are performed by opening small incisions and thus the wound area of the patient is closed very easily. This allows the patient to be discharged in a short time.

This method, also known as Loop Gastik ByPass, was created by the modification of classical methods. It is used as a first-line therapy for obese patients and is preferred as a complementary procedure for patients who have undergone tube gastric surgery more recently but have not achieved the desired weight.

Mini By Pass is one of the most effective methods of diabetes control and permanent weight loss. It is very important to pay attention to the intake of vitamins, minerals and especially protein due to the decrease in absorption.

How is Mini Gastric Bypass Surgery Performed?

The purpose of mini-gastric bypass surgery is to reduce the volume of the stomach and reduce the amount of food absorption through the intestine, so that the patient experiences weight loss. Mini gastric bypass surgery consists of 2 stages. In this laparoscopic (closed) operation, the patient is treated with 5 small incisions instead of a large incision. Each of these cuts is smaller than one centimeter. In the first stage, with the help of special devices, the holes are entered into the abdomen and a small tube is created at the entrance of the stomach, which we will call a new stomach. Because the holes are small, there is no organ that is pulled out and cut. Most of the stomach remains in the abdomen. In the second stage, the stomach and intestine are connected to each other. Two methods are used at this stage; either stapler connections are created or the suture method to connect the stomach and intestines are provided. The stitching application mentioned herein is more preferred by physicians. Because each tissue is handled by physicians one by one and the probability of leakage decreases to a much lower level. Thus, the patient may begin consuming fluid immediately after the operation.

How to achieve weight loss with Mini Gastric Bypass Surgery?

There are 3 stages of weight loss with mini-gastric bypass surgery.

Reduction of stomach size
With this surgery, the stomach volume is reduced. With the shrinking new stomach, the food portions are also reduced. This technique has similar effects with sleeve gastrectomy technique. However, a larger gastric tube is created during sleeve gastrectomy. Consequently, more volume restriction is achieved in mini gastric bypass surgery.

Restriction of Absorption
With the Mini Gastric Bypass method, food passage is stopped in the 200 cm section at the intestine entrance. The separated part is not completely disabled. It continues the transport of fluids that lead to absorption and digestion. Residual edible foods are transferred to the middle of the small intestine after passing through the small stomach through the inserted gastric tube. At this point they are provided with bile. In this way, absorption starts from the middle part of the intestine and excess calories in the body are excreted without being absorbed. As a result, excess calories in the body are excreted without being absorbed. This absorption limiting effect ensures that the amount of weight loss is high and the resulting weight loss is maintained for a long time.

Hormonal Regulation
After the Mini Gastric Bypass procedure, the excess stomach remains passively in the abdomen. Thanks to this operation, there is no food and beverage passage through the large stomach which has lost its function. . Therefore, this part is not stimulated by foods and gradually loses its effectiveness. . Fasting hormone secreted in the large stomach gradually decreases. This manifests itself as less hunger and longer satiety.

What are the Advantages?

  • Laparoscopic method is done. In this way, the wounds heal quickly and the patient can be discharged from the hospital in a very short time.
  • The operation time is short.
  • Effectively reduces food intake.
  • It is a very successful operation in reaching the desired weight.
  • Less intestinal obstruction is seen.
  • There is no foreign object in the body.
  • There are no cut or removed parts.
  • Easily reversible.
  • Reduces hunger and increases saturation.

What are the disadvantages?

Bile Reflux: Bile reflux occurs when the bile from the liver escapes into the stomach and the stomach is irritated. A pyloric muscle is given before surgery and this bile is prevented from escaping from the stomach. However, in Mini Gastric Bypass surgery, the pyloric muscle remains dysfunctional over the blind stomach. Therefore, the bile from the liver descends downward, without obstruction. Therefore, after Mini Gastric Bypass, patients are at risk of severe bile reflux and alkaline reflux gastritis.

Blind Stomach Problem: Mini Gastric Bypass surgery to create a new stomach, the old stomach remains closed as it is. Therefore, the chance of performing endoscopy is eliminated and early diagnosis or non-surgical treatment options are eliminated in case of possible problems.

Stomach Ejaculation Difficulty: When the stomach is divided into two parts, the neural stimulus of the old stomach is completely severed. These nerves are called “VAGUS NERVES”. In other words, in Mini Gastric Bypass operation, a voluntary ot vagotomy B is performed. It is well known that the Pyloric muscle, which controls gastric outlet after vagotomy, is able to close the outlet completely by contracting. For this reason, in the past, the patient underwent vagotomy for ulcer treatment and at the same time, a separate route was made from the pyloric muscle and the stomach was connected to the small intestine by another route. However, in the Mini Gastric Bypass operation, the only drainage channel of the remaining stomach is still through the Pyloric muscle, but the pyloric function is impaired due to vagotomy.
