Multivariate analysis of risk factors for death following gastric bypass for treatment of morbid obesity.

摘要: More than half of Americans are overweight, and more 1 in 5 obese.1 The prevalence obesity has tripled the last 30 years. This resulted significant costs to society both lost productivity increased health expenditures. It is estimated that 300,000 deaths a year related close $100 billion spent on obesity-related care costs.2 Diet exercise therapy frequently associated with weight loss failure.3 Currently, surgery offers only effective long-term for morbidly obese patients. Increased media attention United States as well newer option laparoscopic treatment led patients surgeons embrace surgical options unprecedented numbers, particularly Roux-en-Y gastric bypass (L-GBP). The reported incidence perioperative mortality varies between 0% 1.5% series open (O-GBP)4–6 L-GBP.7–10 With increasing popularity performance GBP, it clear operative this procedure will attract greater public scrutiny. No prior population-based study been able delineate independent predictors death. Two large have defined risk factors complications but were unable do same mortality.11,12 Livingston et al did show significantly higher older 55 years, he was age ultimately predictive mortality.11 It important define so can give potential better information, obtain accurate informed consent, possibly avoid unacceptably high-risk operations. Death after GBP infrequent, assessment requires We used prospective database 2000 procedures over 10-year experience, including O-GBP L-GBP, early death using multivariate logistic regression analysis. results should benefit surgeons, patients, general understanding operation.
