One Anastomosis Gastric Bypass (OAGB)

This surgical technique is used in obesity patients with diabetes mellitus and in revision and conversion procedures.

In this surgical technique, in the first phase, stomach is incised from incisura angularis, stomach capacity is reduced and tube-shape is given. In the 2nd phase, small intestine is specified between 150-200 cm on average (this length varies depending on body mass index, diabetes mellitus presence, total length of small intestine and metabolic rate of the patient). In 3rd phase, single anastomosis (connection) is applied between specified small intestine part and stomach, so that food entering the stomach passes with bypass through the that part of the small intestine.

 In this technique applied especially in type 2 diabetes patients, it is aimed to restrict the stomach and to accelerate food passing to the last part of small intestine, called ileum, to increase secretion of hormones and some substances in that area. So that, ß (beta) cells which are not functioning in pancreas will start to function and insulin resistance is reversed. In that way, patients will get rid of Type 2 diabetes mellitus.

After this operation, 85-90% of diabetes cases are regulated and patients quit the medication. With this surgical technique, capacity of the stomach can be adjusted. This procedure is applied for type 2 diabetes patients, where insulin cannot be controlled with operation and who have a normal c peptic level and whose body mass index is less or more than 30. In our clinic, we performed this operation for the patients whose body mass index is 30 and above, in particular.

⦁ Insulin resistance decreases with a decrease in Ghrelin, known as the hunger hormone,

⦁ Calorie is restricted with a smaller stomach.

⦁ As the foods reach ileum early, GLP-1 release increases.

⦁ GLP-1 stimulates the pancreas to increase insulin production and reduce insulin resistance.

Advantages of mini-gastric surgery

– Short surgery time

– Highly effective in losing weight

– It is a reversible operation.

Disadvantages of mini-gastric surgery

  • After the operation, patients have to use vitamin and some minerals lifelong.
  • It is hard to examine bile ducts with E.R.C.P after operation

Post-op period

Early-stage process after the operation is similar to sleeve gastrectomy. After this surgery, the patient starts walking at the 3rd hour. We make the patient drink water at the 8th hour, and we do a gastric leakage test the next day.  Patients discharged from the hospital in 1 day can return to their daily lives.

We offer hotel accommodation for 2 days to our patients coming from abroad and they return to their countries comfortably on the 3rd day.

Patients come for follow-up examinations on 10th day, in 1st, 2nd, 3rd, 6th month, 1st and 2nd year. In this process, it is very important for patients to apply the diet and to start the sports. Patients need to make a habit out of healthy diet and sport.

We have 7 golden rules.

1- drinking plenty of water

2- taking vitamins

3- eat a protein-heavy diet

4- exercising

5- eating small portions
