Background. many institutions mandate preoperative weight loss prior to bariatric surgery. this study examines the correlation between preoperative weight change and postoperative success following laparoscopic roux-en-y gastric bypass. methods. we retrospectively studied the correlation between change in bmi before surgery and change in bmi postoperatively,using linear regression analyses and one-way anova,in 256 consecutive gastric bypass patients with 1-year followup. results. of 256 patients,125 lost weight preoperatively (mean -1.7 % bmi),while 131 maintained or gained weight (mean +1.2% bmi). postoperatively,there was no significant difference in percent bmi loss between the two groups (34.6% and 34.5%). the percent change in bmi preoperatively did not predict postoperative bmi change after 1 year (p=n.s.). conclusions. our study did not show any correlation between preoperative weight change and postoperative weight loss after roux-en-y gastric bypass. therefore,we do not believe that potential patients should be denied bariatric surgery on the basis of their inability to lose weight preoperatively. © 2010 dan eisenberg et al.
