MGB
Mini Gastric Bypass

General information
General information
Mini Gastric Bypass (MGB) is a bariatric surgical procedure developed by Robert Rutlage. The procedure reduces food intake and diminishes the absorption of nutrients from the food. Absorption of nourishing ingredients is limited because part of the intestines is bypassed and not used. The volume of the stomach pouch after MGB is between 15 and 25 ml.

not possible
The Surgery
Technical description
Mini Gastric Bypass reduces the size of the stomach through surgical stapling. This type of weight loss surgery cuts the stomach and leaves a reservoir of approximately the size of a walnut. Afterwards the biliopancreatic limb is measured (about 200cm). The separated intestine is connected to the stomach pouch (Gastro-enteroanastomosis GEA) mostly with the round stapling method. This causes the food to be directed immediately from the stomach to the jejunum.

Weight loss differences
The EWL after Mini GB reached 70% after five years in the best series.
After the second or third postoperative year, the patient seems to adapt to the surgery and to suffer its side effects in lower intensity, which brings a tendency for a slight weight gain / of lost weight. The weight gain is slight compared to the conventional Gastric Bypass.
