What is Mini-Gastric Bypass?

Mini-gastric bypass, or single anastomosis gastric bypass, is an effective and well-established procedure which combines some of the properties of a gastric sleeve and a standard gastric bypass. The upper part of the stomach is divided into a tube and then joined to a loop of intestine.

The mini-gastric bypass can be used as a primary weight loss procedure. It can also be used in patients who have had previous gastric banding or sleeve surgery but have been unsuccessful with weight loss, or who have had band-related complications and have decided on revision surgery.

How does the mini-gastric bypass help you to lose weight?

  • By reducing the feeling of hunger through the altered gut to brain signaling
  • By enabling an earlier feeling of satiety and fullness when eating a meal resulting in a healthy portion size
  • By decreasing the number of calories you absorb from your food as a result of bypassing 150 to 200cm of the upper part of the small intestine
  • Rerouting of the food stream produces changes in gut hormones that reverse one of the primary mechanisms by which obesity-induced type 2 diabetes occurs

How is the Mini-Gastric Bypass done?

The mini-gastric bypass procedure is performed laparoscopically (keyhole surgery) under general anesthesia. Five to six small incisions (between 5 and 12mm in length) are made for the insertion of the keyhole surgery instruments. Using these instruments, the top of the stomach is stapled to form a thin tube that becomes the new, smaller stomach and is completely separate from the rest of the stomach. This stomach is then sewn to a loop of the small intestine, bypassing the first part of the intestine called the duodenum and approximately 150–200cm of the bowel. The rest of the stomach and upper part of the small intestine remains in the body but is no longer used for food digestion. In skilled hands, the surgery takes approximately two hours.

What are the long-term effects of the mini-gastric bypass?

As with all medical procedures, individual results and experiences may vary.

Several studies have been carried out and published in the long term (over 5 years) effects of mini-gastric bypass surgery. Two years after the surgery, weight loss is 75-85% of excess body weight; five years after the surgery, the excess body weight loss is 70-75%.

Weight loss with mini-gastric bypass is as good, if not better than that achieved with standard gastric bypass surgery in people with a higher BMI.

Many diseases connected to being overweight like sleep apnoea, type 2 diabetes, joint diseases, high blood pressure or polycystic ovary syndrome (PCOS) improve or disappear as a result of the surgery

This procedure should be performed at tertiary care centers with a dedicated bariatric team of surgeons/anesthetists and strong ICU back up
