Tailoring Surgical Treatment for the Individual Patient

Bariatric surgery numbers have changed over time in the USA. Sleeve gastrectomy (SG) has gained popularity during the last years, leaving Roux-en-Y gastric bypass (RYGB) behind in terms of numbers. The objective of this chapter is to analyze the reason for this change, while evaluating outcomes related to type 2 diabetes, weight loss, complications, and gastroesophageal reflux disease (GERD). It seems that RYGB would be more beneficial for obese patients with type 2 diabetes, showing better weight loss, and resolution of GERD. Complication rates are higher for RYGB; nevertheless, complications after SG are sometimes difficult to deal with.
