What is Gastric Bypass Surgery?

Gastric bypass describes changes to the digestive system that aim to reduce a person's calorie intake. It has two purposes:

To restrict food intake
Reducing food absorption

If we look briefly at the history of bariatric surgery, we can better understand its logic.

American surgeons first experimented in the 1950s with short cuts in the intestines (bypasses) in overweight people so that food could not be absorbed, but they abandoned this method after cases of diarrhea, osteoporosis, liver failure and even death. In the 960s, they focused on the stomach. They inserted a silicone ring (gastric clamp) into the entrance to the stomach, but over the years it caused injuries to the stomach, so they abandoned that too. Then, when they observed that ulcer patients who had part of their stomach removed were losing weight, they focused on reducing the volume of the stomach and started to perform gastric bypass surgery. In other words, they both reduced the size of the stomach and created a shortcut in the intestine (gastric bypass). When the closed method, laparoscopy, was introduced in the 90s, they decided to divide the surgery into two stages because gastric bypass surgery took too long and complications increased in overweight patients. They told the patients to do only stomach reduction and come back after 1 year. But something unexpected happened! The patients did not come back for the bowel surgery (bypass) because they had all lost weight. In this way, by coincidence, the most common 'TUBE STOMACH SURGERY' was discovered!

We put gastric bypass surgery in the second stage, inspired by the American experience. Gastric sleeve gastrectomy is more than enough to lose weight and get rid of comorbidities. However, if there is weight gain again for different reasons, we revise the sleeve gastrectomy and turn it into gastric bypass.

Although there are multiple gastric bypass methods, rny gastric bypass is the most commonly used. It is followed by mini gastric bypass and duodenal switch.

Why weight gain after sleeve gastrectomy?

The most common cause of weight regain is the regrowth of the stomach volume or the fact that the sleeve gastrectomy was initially made larger than standard. Especially when the upper part of the stomach is not completely removed, it is easy to expand because it has thin walls. When this area expands, the amount of food taken at one time increases and weight gain occurs.

How much weight do I need to be to have sleeve gastrectomy?

For gastric sleeve surgery, you need to be at least 25 kilograms above your normal weight. Body mass index should be above 35. Diabetics between 30-35 can also undergo surgery.

Mr. Samet will meet you at the hospital and accompany you during your pre-operative tests. These tests take approximately 2 hours. You will settle into your hospital room while you wait for the test results. Approximately 30 minutes before your surgery, our teacher Koray will come and visit you in your room. You will be given a sedative before the surgery and taken to the operating room on your bed. Your surgery will be performed under general anesthesia, so your hour-long surgery will feel like 1 second. You will stay in the recovery room for 30 minutes after the surgery. When you go to your room, the nurse will give you painkillers and anti-nausea for any pain or nausea you may have. There will be no drain catheter in your body. You will be able to get up and walk on your own 2 hours after arriving in the room. 1 companion can stay with you in the hospital. There is no harm in being alone. The morning after your surgery, you will undergo an x-ray and a stomach x-ray will be taken. Here you will be given a drink mixed with cherry juice.
