The Mini-Gastric Bypass: Experience with the First 1,274 Cases

Background: Results of the laparoscopic Mini-Gastric Bypass (MGB) are reported. Methods: 1,274 MGB patients are continuously monitored as part of an online computer tracking data-base system. Results: Mean preoperative weight (± Standard Deviation) was 132 ± 21 kg, BMI 47 ± 7. Mean excess weight loss was 51% at 6 months, 68% at 12 months and 77% at 2 years. The mean operating-time was 36.9 ± 33.5 minutes. The shortest time was 19 minutes. Hospital stay was 1.5 ± 1.6 days. The overall complication rate has been 5.2%.The overall rate of deep vein thrombosis and pulmonary embolism was 0.08% and 0.16% respectively. The leak rate was 1.6%. There was one hospital death, 0.08%. Associated medical illnesses were either completely reversed or markedly improved. Conclusions: The MGB is safe, results in major weight loss, has a short operating-time, and has a short hospital stay.The MGB appears to meet many of the criteria of an "ideal" weight loss operation.
