Gastric Bypass is one of the most effective surgical methods used in the treatment of obesity. It is also used for revision of bariatric operations. This procedure, in which the stomach volume is reduced and fat absorption is reduced, prevents diseases such as obesity-related diabetes. Before gastric bypass, the patient's suitability for surgery should be planned in advance and the process should be well managed.
We perform gastric bypass operations meticulously with our doctors who are experts in the field of obesity. In the free preliminary examination, the most appropriate obesity treatment is determined for you and your doctor informs you about the process. You will benefit from our free dietitian support for three months after the surgery.
Preparation Before Gastric Bypass
Before surgery, patients are given a diet program. Thus, some weight is lost, reduction in liver size is achieved and the risks associated with surgery are minimized. If the patient uses alcohol and cigarettes, it may be necessary to minimize or even stop them completely for a while. This is important in terms of speeding up the healing process.
Before the operation, routine tests are performed to evaluate the patient's suitability for surgery. The patient who will undergo obesity surgery should be fasting for at least 10 hours and without water for 8 hours before the examinations. If no abnormality is observed as a result of the tests, gastric bypass surgery is started.
How is Gastric Bypass Applied?
•Gastric bypass is performed with the laparoscopic (closed) method.
•It is an obesity surgery performed under general anesthesia.
•By opening 4-6 holes with a diameter of 1 cm, the stomach and surrounding tissues are reached.
•While imaging and examination are performed with some of the surgical instruments, the operation is completed with the others.
•The stomach is divided into two parts so that 5% of the stomach remains at the junction with the esophagus.
•Both parts of the stomach remain inside. The newly formed stomach is connected to the small intestine.
What are the Different Applications of Gastric Bypass Surgery?
Gastric bypass, Roux-en-Y (proximal)
This variant is the most commonly used gastric bypass technique and is the most commonly performed bariatric procedure in the USA. It is the operation that causes the least nutritional problems. A gastric pouch of less than 30 mL is proximal to the stomach entrance. This new stomach pouch has a volume of less than about 1 tea cup. By creating a stomach pouch, the existing stomach is deactivated and the food is brought here. It is taken from the distal part of the small intestines (large intestine) and cut about 50-75 cm and connected to the newly formed stomach pouch. The end of the small intestine, which is left behind and from which bile and pancreatic fluid flows, approaches the intestine 70-80 cm ahead and is joined to the intestine again.
Gastric Bypass, Roux-en-Y (distal)
Normal small intestine is between 600-1000 cm. The end of the intestine coming from the bile is connected with the intestine from which the food comes from about 1 meter further. Combination of bile with food towards the end of the small intestine causes malabsorption (decreased absorption) of mainly fats and starches, but also various minerals and fat-soluble vitamins. Unabsorbed fats and starch pass into the large intestine. This can provide faster weight loss. However, more serious nutritional problems (such as severe vitamin deficiency) may occur. In addition, the bacterial activity here can cause the production of irritants and the formation of malodorous gas.
Loop Gastric Bypass (Mini Gastric Bypass)
Here, the intestine is directly joined to the stomach without dividing it into two. Although it is simpler to create, this method causes the bile and pancreatic enzymes to escape from the small intestine to the stomach and then to the esophagus, causing severe inflammation and ulceration in the esophagus. Although it is simpler to implement, it is not a preferred method.
Considerations After Gastric Bypass
After gastric bypass surgery, patients are hospitalized for 3-5 days. In this process, all medical care and controls are carried out. In this process, it is important to pay attention to the nutritional recommendations of your doctor. It is recommended to stay away from carbonated drinks and prepared foods. You need to consume the foods determined by your dietitian, who will prepare and follow-up a nutrition program for you for 3 months.
Who Can Have Gastric Bypass Surgery?
For Gastric Bypass surgery, being between the ages of 18-65, having a body index of 35 and being the first criteria. As a result of the patient's history and detailed examinations, as long as there are no diseases that prevent surgery, anyone who meets these criteria can have gastric bypass surgery. Your doctor will evaluate your situation and determine the most accurate obesity treatment.
