Revisional Bariatric Surgery

Bstract Background: To elucidate percent excess body weight loss (%EBWL) gained from revisional surgery and to determine resolution of comorbid conditions given the obesity epidemic. Methods: All patients undergoing revisional bariatric surgery from 2002 to 2012 were analyzed. Main outcome measures were %EBWL, resolution of comorbid conditions and complications. Descriptive statistics and paired t-tests were computed. Results: 251 cases were performed. Initial mean body mass index was 48.1 kg/m2 (+/- 9.4). Hypertension (32%) and treatment failure (37.5%) were most commonly reported. Mean percentage difference between reoperation and last weight and original and reoperation weight was 27.9% (29.5%), p<0.001. Proportions of all comorbid conditions decreased, but none statistically. No deaths occurred, however 22% experienced at least one complication. Conclusions: Greater %EBWL occurs between revision surgery and last follow-up. No comorbid condition decreased. Further research is needed to determine the optimal timing for revisional surgery to optimize %EBWL and resolution of comorbid condition.
