Morbid obesity has become a major public health problem. During the past 2 decades, bariatric surgery proved to be effective in the treatment of morbid obesity, and laparoscopic Roux-en-Y gastric bypass is currently the gold standard treatment because of its effectiveness and safety profile.
In an effort to simplify the operative technique, Rutledge described the laparoscopic mini-gastric bypass. A long and narrow gastric tube is created similar to the vertical part of a sleeve gastrectomy. Then the jejunum is mounted antecolically 200 cm from the ligament of Treitz, and an end-to-side anastomosis is created with the gastric tube.
The studies published to date are promising and show that the mini gastric bypass for treatment of morbidly obese patients is safe and effective in the long-term. Its promising quality of life results and high effectiveness in the treatment of life threatening co-morbidities such as type 2 diabetes and hypertension, support its use in the treatment of morbid obesity. Results should be confirmed by further studies.
