Excess body mass index loss at 3 months: A predictive factor of long-Term result after sleeve gastrectomy

Introduction. laparoscopic sleeve gastrectomy (sg) is considered as successful if the percentage of excess body mass index loss (% ebmil) remains constant over 50% with long-term follow-up. the aim of this study was to evaluate whether early % ebmil was predictive of success after sg. methods. this retrospective study included patients who had sg with two years of follow-up. patients had follow-up appointments at 3 (m3),6,12,and 24 months (m24). data as weight and body mass index (bmi) were collected systematically. we estimated the % ebmil necessary to establish a correlation between m3 and m24 compared to % ebmil speeds and calculated a limit value of % ebmil predictive of success. results. data at operative time,m3,and m24 were available for 128 patients. pearson test showed a correlation between % ebmil at m3 and that at m24 (r=0.74; p<0.0001). % ebmil speed between surgery and m3 (p=0.0011) was significant but not between m3 and m24. a linear regression analysis proved that % ebmil over 20.1% at m3 (p<0.0001) predicted a final % ebmil over 50%. conclusions. % ebmil at m3 after sg is correlated with % ebmil in the long term. % ebmil speed was significant in the first 3 months. % ebmil over 20.1% at m3 leads to the success of sg. © 2017 guillaume philouze et al.
