Abstract

One anastomosis gastric bypass has grown rapidly in popularity. The operation has gained acceptance worldwide and not surprisingly may become the primary bariatric operation utilized in the surgical treatment of obesity in many countries. Increasing numbers of prospective and randomized studies demonstrate a consistently low complication and mortality rate. Many published series demonstrate favorable short-term and long-term outcomes including reliable and consistent weight loss, comorbidity resolution, and low incidence of malnutrition.
