Mini Gastric Bypass (MGB)

Mini gastric bypass surgery (MGB) is a laparoscopic weight loss surgery that can be revised. It is very similar to the traditional RNY bypass but only has one connection (single anastomosis) to the small intestine. Compared to gastric sleeve surgery and RNY, the MGB procedure is less invasive and requires less time for surgery and recovery.

Instead of a small pouch like with the gastric bypass, the mini gastric bypass surgery procedure creates a narrow tube-like pouch that holds approximately 1-2 ounces, restricting the amount of food that can be taken in at one time. The small intestine is then attached or looped to the new pouch approximately six to seven feet from its starting point. This placement bypasses the part of the intestines that allows for less nutrients, calories, and fats to be absorbed by the body, causing weight loss.

MGB is a mal-absorptive and restrictive procedure. Because you will eat less and absorb fewer calories, you will lose weight. Following surgery, and for the remainder of your life, it is important to take a bariatric multivitamin, calcium, vitamin B12, and iron (for women of menstruating age). With MGB, patients who employ proper nutrition, diet, and exercise can expect to lose up to 70% of their excess weight. They are also more likely to experience an overall well being and reduction of many co-morbidities associated with a person suffering from obesity.

Because this is a laparoscopic procedure, and no large incision is needed to perform mini gastric bypass surgery, there is a lower risk of large surgical scars or hernia. This procedure has a shorter operating time and less post-op complications reported.

Recent studies have shown that patients can expect to lose similarly to the traditional bypass, up to 60 – 65% of their excess weight by the end of the first year, and slightly more by the third year post-op.
