Perioperative outcomes of revisional laparoscopic gastric bypass after failed adjustable gastric banding and after vertical banded gastroplasty: experience with 107 cases and subgroup analysis.

Background: A growing number of revision procedures are to be expected in bariatric surgery after failed restrictive procedures such as failed adjustable gastric banding (AGB) or vertical banded gastroplasty (VBG). Conversion to revisional laparoscopic Roux-en-Y gastric bypass (ReLRYGBP) has been advocated as the procedure of choice.

Methods: The results of ReLRYGBP were reviewed in a retrospective chart review.
