Objective: With drastic variations in bariatric practices, consensus is lacking on an optimal approach for revisional bariatric surgeries. Materials and Methods: The authors reviewed and consolidated bariatric surgery literature to provide specific revision suggestions based on each index surgery, including adjustable gastric band (AGB), sleeve gastrectomy (SG), Roux-en-Y gastric bypass (RYGB), biliopancreatic diversion with duodenal switch (BPD-DS), single anastomosis duodenal-ileal bypass with sleeve (SADI-S), one anastomosis gastric bypass (OAGB), and vertical banded gastroplasty (VBG). Results: AGB has the highest weight recurrence rate and can be converted to RYGB, SG, and BPD-DS. After index SG, common surgical options include a resleeve or RYGB. The RYGB roux limb can be distalized and pouch resized in context of reflux, and the entire anatomy can be revised into BPD-DS. Data analyzing revisional surgery after a single anastomosis duodenal-ileal bypass with sleeve was limited. In patients with one anastomosis gastric bypass and vertical banded gastroplasty anatomy, most revisions were the conversion to RYGB. Conclusions: As revisional bariatric surgery becomes more common, the best approach depends on the patient’s indication for surgery and preexisting anatomy.
