Mason Gastric Bypass: An 8-Year Study of 171 Patients

The document describes an 8-year study involving 171 patients who underwent the Mason gastric bypass for massive exogenous obesity. The study found that a smaller pouch, used in 145 patients, was more effective than a larger one, resulting in significant weight loss and a low postoperative complication rate of 5.5%. The average weight loss in this group was 42% of total body weight, or 121 pounds, and 72% of excess weight. Only 9 out of 145 patients failed to maintain a weight loss of over 25%. The study concluded that the Mason gastric bypass is a superior surgical option for weight loss, with fewer complications and the need for revisions than other procedures like the Alden gastric bypass and horizontal gastroplasties.
