Mini gastric bypass surgery restricts food intake and prevents absorption. It has emerged as an alternative to gastric bypass surgery, and its popularity has increased, as it can be applied more easily.
Similar to sleeve gastrectomy surgery, mini gastric bypass surgery is recommended for individuals between the ages of 18-65, BMI >40 kg/m2, having at least 2 previous experiences in weight control.
Another group includes patients with a BMI between 35 and 39.9 kg/m2, having obesity-related comorbidities (especially diabetes, insulin resistance, sleep apnea, etc.), and unsuccessful weight loss experience.
Like all bariatric interventions, Mini Gastric Bypass surgery is laparoscopically performed. The surgery has two parts. First, a long and thin pouch is created in the part of the stomach that is connected to the esophagus. Unlike sleeve gastrectomy, the rest of the stomach is not removed. But food does not enter this section.
In the second part of the surgery, the small intestine is connected to the newly formed gastric sac without being separated.
Although the operation time varies according to the anatomical structure of the patient, it takes longer than sleeve gastrectomy surgery and shorter than RYGB. However, the time to return to the service bed, together with the pre-operative preparations and post-anesthetic recovery, is approximately three to four hours. Patients generally do not need intensive care after the standard procedure. However, if necessary, close follow-up in the intensive care unit for one night may be appropriate in patients with co-morbid health problems. The patient can get out of bed four to six hours after returning to the service bed and can meet their basic needs.
As in Gastric Bypass surgery, portion reduction is achieved with the small stomach pouch created in Mini Gastric Bypass surgery. With the gastro-intestinal connection made at the same time, the absorption of food is reduced due to the transportation of the food without using a part of the intestines. In this way, the patient gets rid of excess weight effectively by eating a regular and balanced diet.
The weight loss effect of Mini Gastric Bypass surgery is more effective than sleeve gastrectomy surgery. The rate of resolution of health problems accompanying obesity is higher.
It is easier to apply and has fewer complications than RYGB.
Long-term weight regain rates are less than sleeve gastrectomy.
Although it is difficult, it is possible to return the anatomy because no part of the body is removed.
Mini Gastric Bypass surgery has a more weight-loss and solving effect on health problems compared to sleeve gastrectomy surgery.
The difficulty and complexity rate of the surgery and the rate of complications are between sleeve gastrectomy and RYGB.
It takes more time than sleeve gastrectomy and requires longer hospitalization and close follow-up.
Since it is an operation that causes malabsorption, there is a need for lifelong use of vitamins and trace elements.
A part of the stomach remains that cannot be visualized by endoscopy.
After Mini Gastric Bypass surgery, as in every obesity attempt, problems such as bleeding, embolism, and leakage from the punching lines may occur. Conditions such as respiratory tract infection, wound infection, surgical site hernia are among the early period problems that may occur after each surgical intervention, and they might be seen in Mini Gastric Bypass.
In the long term, the most common problems that may occur in Mini Gastric Bypass surgery are less common than traditional gastric bypass surgery. The formation of gallstones, the development of ulcers in the stomach, dumping syndrome, ulcers, and obstruction in the intervened small intestine are among the possible risks.
Diet after Mini Gastric Bypass surgery is similar to RYGB. During the hospital stay after the operation, intravenous serum support is given. If everything is alright in the first 24 hours after the surgery, clear liquids such as water and apple juice and food intake are started. Unlike sleeve gastrectomy surgery, there is no liquid feeding period. However, in the first four weeks, pureed food is consumed. Food containing fat and high-calorie is avoided. A healthy and balanced diet must be followed after all obesity attempts. This process is shaped by dietitians according to the current state of the patient. Protein supplements are used for the first four weeks. During this period, water consumption has vital importance. It is essential to pay attention to portion restriction and solid-liquid separation.
Mobility is crucial in the earliest postoperative period. In-home walks are recommended for the first two weeks after surgery. After the third week, daily outdoor walks should be started on a flat and non-sloping area. In the fourth to six weeks, gradually increasing resistance exercises and weight training after the eighth week can be started. It should be kept in mind that regular exercise is essential for obtaining healthy and permanent results after surgery.
