Prognosis for Metabolic and Bariatric Surgery
In hospitals accredited by the American Society of Bariatric Surgery as centers of excellence (COE), in-hospital mortality was 0.08% ( Prognosis references ). However, some data indicate that lower rates of serious complications are predicted more accurately by the number of procedures done in the hospital and by the surgeon than by COE status. Risk of death associated with bariatric surgery is about 0.1%; overall risk of serious complications is about 4%. For most patients, the risk of obesity and its complications outweigh the immediate risk of surgery ( Factors that predict higher risk of mortality include a history of Deep Venous Thrombosis (DVT) or Average excess weight loss depends on the procedure. Forsleeve gastrectomy,loss of excess weight is 33 to 58% at 2 years 58 to 72% at 3 to 6 years ForRoux-en-Y gastric bypass,loss of excess weight is 50 to 65% after 2 years Weight loss after RYGB is maintained for up to 10 years. ForBPD-DS and SADI-S, patients lose 75 to 90% of excess body weight In people who have severe obesity (≥ 50 kg/m2), weight loss is greater after BPD-DS than after RYGB ( Prognosis references ). Comorbidities that tend to abate or resolve after metabolic and bariatric surgery include a large number of cardiovascular risk factors (eg, Dyslipidemia , hypertension, diabetes), cardiovascular disorders, diabetes, 1.Gebhart A, Young M, Phelan M, Nguyen NT: Impact of accreditation in bariatric surgery.Surg Obes Relat Dis10 (5):767–773, 2014. doi: 10.1016/j.soard.2014.03.009 Epub 2014 Mar 15. 2.American Society for Metabolic and Bariatric Surgery: Metabolic and Bariatric Surgery.
