Your diabetes has been treated, your sleep apnea has been treated, your blood pressure has returned to normal and you have stopped using medication. You can take long walks, bend over and tie your shoes. You can ride a bike. All these sentences contain things that are difficult for people with obesity to imagine. It is possible to beat obesity with Gastric Bypass surgery.

Koru Ankara Hospital offers obesity patients more advanced methods to change their lives. The most important of these is Da Vinci Robot-Assisted Gastric Bypass surgery. In a surgery performed with minimally invasive techniques, patients recover faster. In this way, hospitalisation times are shortened.


Gastric bypass surgery is a suitable solution for morbidly obese patients. These patients are people who have tried every way to lose their weight but failed. With the Da Vinci Robot-assisted gastric bypass surgery performed in Koru Ankara hospital, effective and sustainable weight loss success is achieved and morbid obesity is prevented. The severity of diseases caused by morbid obesity is also reduced. As a result, patients' quality of life improves.

For morbidly obese patients who have tried but failed all conservative methods and measures, including diet and exercise, to control their weight, gastric bypass surgery is a viable alternative. The more important the decision to have an operation to solve the weight problem, the more important is the type of surgery and the technique to be applied. For over 50 years, many types of surgeries have been found for the treatment of obesity and these surgeries have been performed with different techniques.

Gastric bypass surgery is an effective, safe and sustainable procedure and has been defined as a gold standard procedure by IFSO (International Federation for the Surgery of Obesity and Metabolic Diseases), ASMBS (American Society of Metabolic and Bariatric Surgery) and NIH (National Institutes of Health).

How does Gastric Bypass Surgery work?

The purpose of gastric bypass surgery means to limit the amount of food people eat and to reduce the absorption of some of the foods eaten. The part called the new stomach or pouch that is created surgically constitutes 3% of the old stomach volume. While the old stomach resembles the size of a soccer ball in volume, the newly created pouch is the size of a baseball. Thanks to this newly created pouch, the person can keep less food inside.

In the second stage, a portion of the intestine is removed. The small intestine of 150 cm on average only allows the passage of food from the stomach, and digestion and absorption do not occur in this intestinal part. Digestion and absorption of nutrients take place in the common small intestinal canal after the union of this 150 cm-long alimentary canal of the small intestine with the bilio-pancreatic duct, which carries bile and pancreatic fluid.

Then, mouthing is made between the 150 cm small intestine that is not absorbed and the stomach pouch. The process is completed with the union of the alimentary canal and the 70 cm bilio-pancreatic canal. Thanks to the restriction and less absorption of nutrients obtained with a small stomach pouch, gastric bypass surgery, which has malabsorption effects, stands out among bariatric surgeries as an effective and sustainable procedure.

How does Robotic Gastric Bypass Surgery work?

In Gastric Bypass surgery, there are two anastomosis mouthing are performed, one from stomach-to-intestines, and one from intestiones-to-intestines. The mouthing of the newly created stomach pouch to the small intestine is the most complex and difficult stage of gastric bypass surgery. The most common techniques used for this laparoscopy are automatic stapler or suturing techniques. Scientific studies have shown that sutured mouthing has the best results. Laparoscopic suturing is a very tiring procedure, even for surgeons with advanced laparoscopic experience.

The Da Vinci Robotic Surgery System, accompanied by a 3D high-resolution image in a narrow area, increases the surgeon's skill and sensitivity and enables easier suturing. Effective and sustainable weight loss success is achieved with da Vinci robot-assisted gastric bypass surgery. The severity of the diseases caused by obesity decreases or even disappears, as a result, the quality of life of the patients increases thanks to Da Vinci Robot-Assisted technology. For more than 50 years, we have sufficient scientific data on gastric bypass surgery in terms of efficacy, safety and sustainability. With gastric bypass surgery, we can achieve the following:

  • We can achieve effective weight loss in the patient.

  • In addition to weight loss, the patient also experiences improvements in morbid obesity-related diseases (hypertension, type 2 diabetes, apnea, etc.).

  • These effects continue in the long term.
