The annual volume of bariatric surgery is growing, giving rise to an increase in complications requiring complex management, including revision. Bariatric revision procedures are also becoming increasingly necessary for weight-loss recidivism and patients at the extreme of obesity. This chapter outlines clinical management pathways used to address secondary bariatric surgery. It summarizes reasons for, and outcomes with, revision of a laparoscopic gastric band, vertical banded gastroplasty, sleeve gastrectomy, or Roux-en-Y gastric bypass. Surgical techniques used to manage weight regain or failed weight loss after bariatric surgery are also discussed. Finally, surgical solutions for bariatric surgery-induced malnutrition are described, particularly in the setting of biliopancreatic diversion, duodenal switch, or jejunoileal bypass. Overall, the chapter concludes that standardization of revisional procedures can have a significant patient impact, and guidelines must be evidence-based in order to ensure patient safety and success.
