Mini Gastric Bypass is technically simpler and the operation time is shorter than Gastric Bypass. Complications are less than traditional gastric bypass. It is an operation that restricts food intake and impairs food absorption. In this technique, a gastric tube is first created, similar to sleeve gastrectomy surgery, but smaller in size. Then, the first 150-200 cm of the small intestine is disabled and the small intestine is connected to the lower end of the newly formed tube stomach.
After mini gastric bypass, weight loss occurs in patients with 3 different mechanisms.
• Food intake is restricted by making a sleeve gastrectomy.
• Food absorption is reduced by disabling the first 150-200 cm of the small intestine.
• Hormonal changes (hunger hormone-ghrelin) level decreases.
The surgery is performed laparoscopically (closed) as in other procedures. It is made from 4-5 holes smaller than 1 cm opened on the abdomen. The postoperative period is the same as in the classical gastric bypass.
To Whom MGB Should Be Made ?
Mini gastric bypass method is preferred in the treatment of insulin-dependent morbidly obese patients. It is more effective in diabetic patients compared to sleeve gastrectomy and classical gastric bypass surgery. In addition, mini gastric bypass is recommended in patients who are extremely obese (BMI>50 – “super obese”) or patients with type 2 diabetes who are at the forefront of type 2 diabetes.
Mini gastric bypass is usually the preferred method for patients who have had sleeve gastrectomy / gastric reduction surgery and gain weight again after years and become morbidly obese. In these patients, the mini gastric bypass procedure is easy and has few complications. The first stage of the procedure (tube stomach) has already been done. A second phase will be added.
Post surgery!
Post operation hospital stay is 3-4 days. Patients are usually kept in intensive care units for the first 1.2 days.
• The patient is mobilized 1 day after the procedure.
• A catheter (tube) can be placed in the stomach for 2-3 days.
• It will not be possible to eat for the first 2 days. If there is no risk of leakage, watery food is started after the 3rd day and then continued with puree or soft foods.
• A tube can be placed from the nose to the stomach for 2-3 days to empty the stomach contents after the surgery.
• To help prevent the formation of blood clots, special socks are put on the feet and legs.
• Medication (heparin) is given to prevent blood clots from forming.
• Painkillers are given intravenously for pain
Possible complications are similar to Roux en Y Gastric Bypass surgery. Vitamin (B1, B6, B12, Folic acid, D) and electrolyte (Fe, Ca) deficiencies that occur due to absorption deficiency are similar to Roux en Y Gastric Bypass but occur more frequently. In the postoperative period, multivitamins (supradyn, pharmaton, etc.) are given to prevent vitamin and mineral deficiencies. In addition, patients are checked every three months and their vitamin and mineral values are measured. Additional supplements are made when a deficiency is observed.
What are the benefits of gastric bypass ?
Most people lose 10 to 15 pounds the first month after surgery. The rate of weight loss will decrease over time. The success rate of losing excess weight after mini gastric bypass is higher than sleeve gastrectomy. In both methods, food intake is limited. However, in addition to gastric bypass, food absorption is also reduced. Therefore, it is relatively superior to tube stomach in losing excess weight. It is also superior to sleeve gastrectomy surgery in the treatment of Type 2 diabetes.
75% of excess weight is lost within 1 year after surgery. Loss of excess weight reaches 80-90% in the second year. Along with the loss of excess weight, a significant improvement is observed in diseases accompanying obesity. Self-confidence comes back. In addition, with the significant decrease in the load on the knee and waist, most of the knee and low back pain will go away on its own.
Advantages
• It is recyclable
• Food absorption rate is lower.
• It is technically easier than the RNY Gastric Bypass operation.
• It creates a more permanent solution to Type 2 Diabetes and other co-morbid diseases.
• The complication rate is low.
• Less likely to regain weight.
