Mini gastric bypass

Mini gastric bypass is the official name for single-anastomosis gastric bypass, and is a type of bariatric surgery aimed fighting obesity. It appeared back in 1997, and 6 years later it began to be actively spread around the world.


Mini gastric bypass surgery is a modification of classical bariatric gastro-bypass surgery. At the same time, a high level of therapeutic effectiveness remains, and is also characterized by easier execution and fewer risks.

Comparative indications of mini gastro-bypass in relation to standard gastric bypass are:

  • poor tolerability of general anesthesia or the need to reduce its duration;
  • presence of pathologies related to the heart and vascular system;
  • high risk of complications after surgery;
  • insufficient ability to recover in patients with diabetes mellitus. It leaves fewer anastomoses and heal faster.

Absolute indications of the need for mini gastric bypass include:

  • body mass index equal to or exceeding 35 kg per sq m;
  • body mass index above 30 kg per square meter in the presence of burdened heredity in the family;
  • presence of obesity in the abdomen;
  • obesity accompanied by type 2 diabetes and heart disease;
  • Type 2 diabetes.

Mini bypass is classified according to the nature of anastomosis formation. Anastomosis - artificial connections between parts of the intestine. They come in two types:

  1. A special crosslinking device is used, which forms these connections between the guts. It is characterized by simple execution, but at the same time does not exclude risks and the occurrence of various kinds of complications.
  2. Performed manually by the surgeon. Eliminates negative consequences and has high efficiency.

One of the modifications of mini gastro-bypass is bariatric surgery on a short loop, in which only 20 cm of the small intestine is removed. It is used in patients whose weight by body mass index does not exceed 30-35 kg per square meter.

How is the surgery performed

Mini gastric bypass is carried out by laparoscopic technique, which involves the creation of microscopic incisions, the length of which does not exceed 5 mm. Subsequently, surgical instruments are inserted through these incisions into the inside, through which work with the stomach will be carried out. Further, the stomach is divided into 2 parts, the smaller of which is left and sutured with the small intestine. The "new" stomach resembles the shape of a tube, the length of which does not exceed 2 cm. At the end of the surgery, antiseptic dressings are applied to microscopic incisions on the skin. 

Mini gastro-shunting is carried out with the use of a general type of anesthesia using anesthetic drugs that provide easy awakening and do not have a sedative effect. The average duration is from 1.5 to 2.5 hours.

Recovery period

Complete recovery from bariatric surgery occurs after a couple of weeks. At the same time, discharge from the clinic is carried out on average in a week. During the recovery period, it is recommended to completely eliminate physical activity, giving preference only to hiking and exercise therapy, as well as carefully monitor nutrition. Immediately after the operation, food should enter the body only in liquid form. After several days, it is allowed to consume mashed potatoes and rougher food, but limiting its energy value and adhering to a fractional diet. The main thing is to exactly comply with all medical recommendations and visit the surgeon at the appointed time to monitor the healing process.

Benefits of life before and after

The results of mini gastric bypass appear in rapid weight loss, as well as noticeable relief or complete disappearance of pathological symptoms in the form of respiratory arrest in sleep, diabetes, high blood pressure and others. In 95% of patients suffering from severe diabetes mellitus, after the operation, they did not need therapeutic measures to combat it, since the symptoms disappeared.
