The mini gastric bypass (MGB) was developed by Dr Rutledge in 1997, and has been gaining popularity ever since. It is a restrictive as well as a malabsorptive procedure. This means it reduces the size of the stomach, restricting the amount of food we eat. It also reduces absorption by bypassing about 6 feet of the small intestine. This is technically simpler, faster and safest weight loss surgery as compared to the traditional bypass surgery. The other advantages of this surgery include the facts that it can be revised according to the body mass index (BMI) of the patient and if necessary it can be reversed.
Patients usually lose about 79% of their excess body weight within eighteen months of the surgery. Obesity-related co-morbidities improve or resolve after bariatric surgery. Diabetes, hypertension, obstructive sleep apnoea, and abnormal cholesterol levels are improved or cured in more than 75% of patients undergoing MGB.
Patients are encouraged to walk from the day of the surgery itself. Most patients are comfortably up and about the next morning and can take a bath themselves.
They are on a liquid diet for one week after the surgery and then progress to soft diet for the next week. From thereafter, they are on a normal diet.
Though the capacity to eat is reduced, it is more than what people experience after a sleeve gastrectomy. People need to be on certain supplements like calcium, iron, and multi-vitamins.
There are certain risks that are common to any laparoscopic procedure such as bleeding, infection, injury to other organs, or the need to convert to an open procedure. There is also a small risk of an ulcer, leak, bleeding or bile reflux. These problems are rare and major complications occur less than 1% of the time.
