Abstract:
The outcomes of bariatric surgery, while often impressive, are not universally satisfactory; they vary from patient to patient and from operation to operation. Between 20-30% of patients experience suboptimal weight loss or substantial weight regain early in their postoperative course. Confronted with this chronic disease, and given that failures are difficult to manage, it is essential to better characterize obesity preoperatively, considering other metrics beyond just the body mass index (BMI), to select the best candidates for surgery and optimize the benefit/risk ratio. Based on the data of the most recent studies on bariatric surgery, our objective is to identify the predictive factors of weight loss as well as the risk factors of failure. Our analysis indicates that the choice of the surgical technique, age, initial BMI, ethnic origin, the presence of eating disorders and metabolic factors all have an impact on weight-loss outcomes after bariatric surgery. Thus, it is of major importance to carefully select patients during a preoperative multidisciplinary discussion in order to optimize weight loss and metabolic outcomes.
