The Mini-gastric Bypass: 15 Years Later

R Rutledge, MD. Center for Laparoscopic Obesity Surgery



There is a growing body of evidence showing that the Mini-Gastric Bypass (MGB) is a safe and effective alternative to other bariatric surgical operations. This study reports on the results of a consecutive cohort of 6,000 patients undergoing the MGB.

A prospective database was used to continuously assess the results in 2,410 MGB patients treated from September 1997 to 2010.

The average operative time was 44 minutes, and the median length of stay was 1 day. The 30-day mortality and complication rates were 0.05% and 5.1% respectively. The leak rate was 0.96%. Average weight loss at 1 year was 64 kg (81% of excess body weight). The most frequent long-term complications remain as previously reported: dyspepsia and ulcers (5%) and iron deficiency anemia (5%.) Excessive weight loss with malnutrition occurred in 1.0%. Weight loss was well maintained over 15 years, with <7% patients regaining more than 10 kg.

As shown in previous studies, the MGB is very safe initially and in the long-term. It has reliable weight loss and complications similar to other forms of gastric bypass.
