Mini gastric bypass surgery is performed laparoscopically. A portion of 80 to 85% of the stomach is separated by accessing the stomach through incisions with a diameter of 0.5 to 1 cm that are made in the abdominal region.

A new gastrointestinal connection is formed with the remaining 10 to 15% of the stomach in the way that approximately 160 to 180 cm of the small intestine are left behind. 80 to 85% of part separated from stomach is not removed and continues to function in the digestive system. In contrast to Roux-en-Y gastric bypass surgery, a new gastrointestinal line is established in this surgical procedure without separating the intestine. Duration of this surgery is shorter since one operation is performed less compared to other obesity surgery techniques.

Individuals whose body mass index is 35 kg/m² or above and have co-morbid diseases such as hypertension, cholesterol, diabetes etc. secondary to obesity can undergo mini gastric bypass surgery.

How Should I Nourish After The Gastric Bypass Surgery?

Depending on the result of the leak test to be done within 48 hours after the surgery, the patient is fed only with liquid for the first 2 weeks. As of the 3rd week, the patient continues to consume mainly liquid and pureed food. As of the 12th week, on the other hand, patient follows a normal nutritional pattern. 

It is beneficial for the patient to take vitamin supplements after the surgery to prevent vitamin deficiency caused by poor nutrition and decreased intestinal absorption. The whole process should be carried out under the guidance of the dieticians with high bariatric experience.

What is Revision Surgery?

Obesity surgery is one of the most prevalent methods used in the field of combating obesity. Surgical procedures such as restrictive, disruptive absorption or restrictive + disruptive absorption are performed with this technique. These procedures are aimed to improve people’s live standards, reform their dietary habits, and encourage them to participate in physical activity. However, the expected goals sometimes cannot be met. It is at this point when revision surgery is considered.

Revision surgery is the requirement of a second operation as a result of being unable to achieve the desired aim with any kind of obesity surgery.
