What is Minigastrik Bypass ?

It is a relatively new procedure that provides satisfactory results in terms of weight loss over a long time.

The stomach is divided into two parts, one large and one small part. While the large part of the stomach is no longer in use, the small part acts like the patient's new stomach. The large part of the stomach remains "active" but is no longer used.

The bypass process: How much of the small intestine is bypassed depends on the patient. Normally it is between 90cm and 180cm. The intestine is transported to the small stomach, where it is bypassed and surgically joined to the stomach. In contrast to the Roux-Y gastric bypass, the small intestine is never completely severed, but connected to the new stomach.

How to lose weight with mini bypass?

  • The new little stomach created during mini gastric bypass reduces the amount you will eat.
  • By reducing the size of the stomach, the level of ghrelin hormones, which makes you feel hungry, decreases. As a result, you don't want to eat as much or as often as you did before.
  • With bypass surgery, foods can bypass the part of the small intestine that is responsible for absorbing high molecular weight such as carbohydrates and fat. Because a part of the small intestine is skipped, fewer calories are absorbed, which contributes to more weight loss.

How is the mini bypass surgery performed?

The operation is performed under general anesthesia using a laparoscopic (closed) technique. With the help of laparoscopic instruments, an incision of two centimeters is made in the abdomen, whereby a camera and instruments are placed and used. The stomach is separated by sewing and cutting at the same time with the help of tools like staplers and steel clamps.

The mini bypass surgery is ideal in those cases:

Patients with a body mass index (BMI) of 40 and higher,

If the BMI is between 35 and 39.9 and a serious health problem (type 2 diabetes, high blood pressure, severe sleep apnea, etc.) exists.

If your obesity has emerged from excessive alcohol consumption or sugary foods, we may recommend gastric bypass surgery.

How long does the surgery take?

Dr. Aynacı does not prefer to perform the surgery on the day the patient arrives. The surgery is performed the following day. After the patient is taken to the operating room, it takes 30 minutes that the patient falls asleep with the help of the general anesthesia and that the surgical materials and positioning are prepared. Dr. Aynacı can only start the surgery after 30 minutes. The surgery itself takes an average of 90 minutes. The patient takes about 15 minutes to wake up. The duration of the surgery takes 2.5 hours in total. When the surgery is over, the patient wakes up in a single room, where professional staff will take care of them in the best possible way.

What is the advantage of the mini gastric bypass compared to the Roux-Y gastric bypass?

The mini gastric bypass is a less invasive surgery compared to the Roux-Y gastric bypass. The gastric bypass is more destructive.

During the mini gastric bypass the intestine is not cut and gets only a connection between the new stomach and the intestine. During the Roux-Y gastric bypass, the intestine is severed and has connections between the stomach and the intestine itself. This makes it possible to perform the mini bypass in a shorter time and this also reduces the risks and complications of mini gastric bypass.

When it comes to weight loss and health benefits, both procedures have roughly the same benefits.

It should be said that the vitamin deficiencies seen in mini bypass patients are not as pronounced as in Roux-Y gastric bypass patients.

Again, MGB patients have a lower "dumping syndrome" than RYGB patients and a lower degree of severity.

If necessary, a mini gastric bypass can be set to a standard bypass. Roux-Y gastric bypass is not a reversible process. It's a permanent surgery. There is no chance of a second surgery.

Risks of the surgery

There are generally always risks involved in surgical interventions. However, obesity surgery itself is not particularly dangerous. Information about the techniques used, the materials used, and the general health of the patient will reduce the risk of surgery. Dr. Aynacı uses all tools and materials only once. The material used is from Medtronic (Covidien) and is made in America.

The risk of mini gastric bypass and Roux-Y gastric bypass is almost the same.

In rare cases, there may be bowel obstructions due to damage to important organs or vessels, bleeding, infections caused by internal or external wounds, peritonitis, leakage from anastomoses, stenoses, wound healing problems, dumping syndrome, thrombosis and embolism, gastrointestinal disorders, allergies, internal herniation.
