The International Federation for the Surgery of Obesity and Metabolic Disorders (IFSO) has played an integral role in educating both the metabolic surgical and the medical community at large about the role of innovative and new surgical and or endoscopic interventions in treating adiposity-based chronic diseases. The single anastomosis duodenal-ileal bypass with sleeve gastrectomy (SADI-S) is also called the one anastomosis duodenal switch (OADS). This is a relatively new procedure that has been proposed as an alternative to the currently accepted duodenal switch (DS) procedure. The IFSO commissioned a task force (Appendix 1) to determine if SADI-S/OADS is an effective and safe procedure and if it should be considered a surgical option for the treatment of adiposity and adiposity-based chronic diseases. The following position statement is issued by the IFSO SADI-S/OADS task force and approved by the IFSO Executive Board. This statement is based on current clinical knowledge, expert opinion and published peer-reviewed scientific evidence. It will be reviewed in 2 years.
