Five-year Outcomes of Sleeve Gastrectomy: A Prospective Multicenter study
AMERICAN SURGEON(2022)
摘要
Background 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. Methods 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. Results 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(2), respectively. Body mass index significantly decreased to 32.2 kg/m(2) at 5 years (P < .001). The mean %EWL was 63.6% at 5 years. A significant reduction in dyslipidemia (28.0%-18.2%), obstructive sleep apnea (OSAS) (34.6%-25.1%), and arterial hypertension (HTN) (30.4%-21.5%) was observed after 5 years, but not for diabetes and gastroesophageal reflux disease (GERD). At multivariate analysis, age >50 years old, BMI >50 kg/m(2), and previous laparoscopic adjustable gastric banding (LAGB) remained independent predictors of weight loss failure. Conclusions 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(2), and previous LAGB were independent predictors of weight loss failure.
