Introduction: Mini-Gastric Bypass (MGB) originated in 1997 as a simple, rapid and mainly malabsorptive bariatric operation; it is now increasing rapidly.

Methods: History, technique, variations and world literature are reviewed.

Results: Reports now find the MGB to be a superior operation with respect to safety, short learning curve, resolution of co-morbidities (especially diabetes), durable weight loss and ease of revision or reversal.

Conclusion: The authors regard MGB as a very favorable operation and present a review.

Mini-Gastric Bypass (MGB or Malabsorptive Gastric Bypass) was devised by Robert Rutledge in USA in 1997. As a trauma surgeon, he was faced with an abdominal gun-shot wound where a duodenal exclusion with a Billroth II anastomosis was an appropriate reconstruction. This was the inspiration that led Rutledge to the MGB on consenting bariatric patients, constructing a long lesser curvature channel which prevents reflux [1,2]. In the USA, there was some skepticism against the MGB.

In 2001, the first author (MD) spent 15 days as a guest in Dr. Rutledge’s O.R. and pre- and post-operative clinic, inspecting his substantial follow-up. The MGB has since increased throughout the world [3-14]. With the decrease in gastric banding, the MGB in 2015 became the third most common bariatric operation internationally [15].

Technique of MGB

The laparoscopic MGB (Figure 1) has two components: 1) a lessercurvature long gastric pouch, serving as a slightly restrictive conduit; 2) a 180-200 cm jejunal bypass with a wide antecolic Gastrojejunal (GJ) anastomosis, which leads to carbohydrate and especially fat malabsorption.
