What is a mini gastric bypass?


A method aimed at controlled weight loss and providing this at a high rate also prevents diseases that will occur due to weight. Mini Gastric bypass, which is one of the preferred methods because the recovery time is short, is an important treatment method for Type 2 diabetes. 

The aim of the method, also known as an alternative to Gastric sleeve surgery, is to reduce the volume of the stomach and give the feeling of being constantly full. In this way, the patient is able to control weight by consuming less nutrients. In addition to the tube created in the stomach with small tools in the operation, the intestinal working mechanism is directed, reducing the absorption rate of nutrients and eliminating them without absorption. 

Mini gastric bypass or as it is called, single anastomosis gastric bypass is a very effective operation and can combine some of the effects of standard gastric sleeve bypass operations. A tube in the upper part of the stomach, and this tube is joined below with the small intestine. Mini gastric bypass can be performed alone as a primary bariatric surgery operation. It can also be used as revision surgery in patients who have previously had surgery but have not been successful or have not been able to lose enough weight.

What is the difference between a gastric bypass and a mini bypass?

Just as in the case of an RNY Gastric Bypass operation, the stomach is divided into two parts. The difference between RNY and Gastric Bypass is that the intestine connects to the stomach without dividing. Thus, in the Mini Gastric Bypass operation, one connection is made less in total. If the absorption is reduced, a longer intestinal section is bypassed in the Mini Gastric Bypass operation than in the RNY Gastric Bypass operation. Due to the fact that the remaining stomach fluids and the passage of bile in its continuation are the ends of the reduced stomach, there is a possibility of bile reflux during a Mini Gastric Bypass operation. In none of the Gastric Bypass surgeries, the stomach is not removed, the stomach is reduced in itself. As a matter of fact, it is extremely advantageous in two operations. In both operations, it reduces the volume of the stomach and provides absorption. Thus, patients lose weight. He is successful at the stage of losing weight in two operations.

Mini Gastric Bypass is an obesity surgery that reduces the volume of the stomach and reduces the absorption of food from part of the small intestine. It is applied by completely closed method. In other words, large incisions are not made on the abdomen. All are applied by making 5-6 incisions under 1 cm. From these holes, a camera and surgical instruments necessary for surgery are placed in the abdomen. The camera and surgical instruments used are special instruments manufactured in a very small and thin structure so that they can pass through these holes. 

At the entrance to the stomach, a small gastric tube is formed and completely separated from the rest of the stomach. The main stomach that will be used after surgery is a new stomach particle that is turned into this small tube. No organ is cut and removed. Most of the remaining part of the stomach remains dormant in the abdomen and continues to produce its secretions.

Closed method (laparoscopic) under general anesthesia with 5 small incisions ranging from 5 to 12 mm and from here the operation is carried out with placed hand tools. A long 50 cc volume tube is formed in the upper part of the stomach. This the connection with the stomach outside the part is severed. This tube is then sewn with the first part of the small intestine, The Twelve-finger intestine.

The other part of the stomach and the first segments of the small intestine are not removed, but they do not function in the absorption of food. Mini gastric bypass surgery takes an average of 60-90 minutes.

Here are the most common risks of mini gastric bypass:

  • The necessity of using vitamins for life
  • The need for careful application in people with stomach cancer in their family
  • Dumping syndrome
  • Stomach runoff of saffron from the liver creates excessive irritation in the stomach. In the Normal case, this condition is prevented by a special muscular system that controls the outflow of the stomach Nov. In a Mini gastric Bypass operation, the pyloric muscle remains dysfunctional on the stomach, which remains blind. Bile from the liver continues down, emptying into the stomach without any obstacles in front of it. For this reason, after Mini Gastric Bypass, patients are at risk of severe bile reflux and alkaline reflux gastritis.
  • In Mini gastric Bypass surgery, the new stomach is created, while the old stomach remains closed inside as it is. Endoscopy cannot be performed after Mini Gastric Bypass surgery on this large part of the stomach, and in case of possible problems, the possibility of early diagnosis or non-surgical treatment is eliminated.
  • The stomach is divided into two parts, while the neural stimulation of the remaining stomach is completely severed. 
  • These nerves are called” VAGUS nerves”. In other words, in Mini gastric Bypass surgery, a “vagotomy” is performed voluntarily. After vagotomy, the pyloric muscle that controls the outflow of the stomach can completely contract and close the outflow, which is a very well-known condition due to ulcer operations performed for 50 years. For this reason, at the same time, the patient who used to have a vagotomy for the treatment of ulcers was made a separate way from the pyloric muscle and the stomach was connected to the small intestine by another way. However, in Mini gastric Bypass surgery, the only excretory canal of the stomach left blind is still through the pyloric muscle, but due to vagotomy, pyloric functions are impaired.

How is the recovery period after mini gastric bypass?


Mini Gastric Bypass is a method that is performed in the fastest, easiest way among the operations performed in obesity surgery and the healing process after the operation is quite comfortable. The hospital admission period after surgery is 3-4 days. Patients are usually kept in intensive care units for the first 1 – 2 days. After surgery, a tube can be placed from the nose to the stomach for 2-3 days to empty the contents of the stomach. In addition, patients are checked every three months and vitamin and mineral values are measured. Additional supplements are made when deficiency is seen.
