BACKGROUND: During @entity356 ( @entity356 ), some surgeons elect to perform a vagotomy to reduce symptoms of @entity354 ( @entity354 ). Routine vagotomy during @entity356 may independently affect @entity353 and metabolic outcomes following bariatric surgery. We aimed to determine whether vagotomy augments percent excess @entity353 in @entity28 @entity1 after @entity356 . METHODS: We examined the effect of vagotomy in 1278 @entity1 undergoing @entity356 at our institution from 2003 to 2009. Weight and percent excess @entity353 (%EWL) were modelled at three months and annually up to five years using a longitudinal linear mixed model controlling for differences in age, gender, initial body mass index (BMI), ideal body weight, and presence of vagotomy. RESULTS: Vagotomy was performed on 40.3% of our cohort. Vagotomy @entity1 had significantly lower initial BMI (46.4  6.2 vs. 48.3  7.7kg/m(2), p<0.001), but there were no other significant differences at baseline. The strongest predictor of %EWL over time was initial BMI, with lower BMI @entity1 exhibiting greater %EWL (p<0.001). Age and gender effects were also significant, with younger @entity1 (p<0.04) and males (p<0.002) attaining greater %EWL. Vagotomy had no effect on %EWL in either simple or multiple regression models. CONCLUSION: Our series suggest that vagotomy does not augment %EWL when performed with @entity356 .
