Sleeve gastrectomy (SG) is the most frequently performed bariatric procedure in the world. Our purpose was to evaluate the percentage of excess weight loss (%EWL), resolution of obesity-related comorbidities after SG, and identify predictive factors of weight loss failure.
A prospective cohort study of adults who underwent SG during 2014 in 7 Belgian-French centers. Their demographic, preoperative, and postoperative data were prospectively collected and analyzed statistically.
Overall, 529 patients underwent SG, with a mean preoperative weight and body mass index BMI) of 118.9 ± 19.9 kg and 42.9 ± 5.5 kg/m, respectively. Body mass index significantly decreased to 32.2 kg/m at 5 years ( 50 years old, BMI >50 kg/m, and previous laparoscopic adjustable gastric banding (LAGB) remained independent predictors of weight loss failure.
Five years after SG, weight loss was satisfactory; the reduction of comorbidities was significant for dyslipidemia, OSAS, and HTN, but not diabetes and GERD. Age >50 years old, BMI >50 kg/m, and previous LAGB were independent predictors of weight loss failure.
