“…This model explains 21 % of ≤50 % EWL, 1 year after bariatric surgery. Five of these variables, including gender, age, preoperative BMI, type of surgery, and type II diabetes, are in agreement with literature [7,8,11,12]. Although waist circumference was found to be a predictor in other studies, this variable gave no improvement to the multivariable model in present study.…”

“…Several articles reported a possible association between suboptimal weight loss and high preoperative body mass index (BMI), personality disorders, and diabetes mellitus [6,[9][10][11]. A previous published multivariable logistic regression analysis showed that young patients with a lower BMI and higher waist circumference achieved more %EWL after 1 year and the success percentage of more than 60 % EWL was higher [12].…”

Introduction:The Roux-en-Y Gastric Bypass (RYGB) has been one of the most popular surgeries in the USA for years. While many models have been made to investigate the factors that affect weight loss, these factors are still highly debated.Objective: To create a model that predict performance of RYGB patients.Methods: 110 out of 344 patients who received a RYGB at a single institution between Jan 2010 and April 2014 were included in this study. Data was collected retrospectively. Patients were included if they had greater than 1 year follow up with at least three follow up points and could be modeled with r 2 >0.95. All patients were one year beyond surgery, while 40 were completely lost to follow up, 104 at 1 month, 138 at 3 months, 188 at 6 months, and 225 at one year. 9 patients were not included because they did not meet the criteria of the study. Patients were divided into quartiles based on percentage excess weight loss (%EWL) at one year.Multivariate analysis was performed to determine the significant factors that influence patients being in the first quartile of weight loss (17-60% %EWL). Results:Only males with a Body Mass Index (BMI) above 44 and females with a BMI above 64 were found to be predictive of patients being in the first quartile. Our model has Positive and Negative predictor values of 66% and 80% respectively with sensitivity and specificity of 29% and 95% respectively. Conclusions:An model to predict %EWL was created, only gender and pre-operative BMI were found to be significant factors. In general females have better outcomes with higher BMI's than do males. This information should be discussed with patients when deciding a procedure. However, more studies are needed for validation of these results.

“…A meta-analysis has shown that patients who had undergone RYGB lost 61.5%, 69.7%, and 71.2% of their excess weight during 1-, 2-, and 3-year postoperation periods, respectively [19]. In addition to weight loss, LRYGB results in decreasing mortality rates of comorbidities such as coronary heart disease and diabetes by more than 50% and 90%, respectively [19][20][21].…”

Predictive Factors of Weight Loss 1 Year after Laparoscopic Gastric Bypass in Obese Patients

Abstract: Initial BMI appears to be a strong determinant of individual WL, but predictive factors differ when WL was expressed as %EWL or AWL. The treatment of diabetes rather than diabetes itself appears to affect WL.
