Roux-en-Y gastric bypass remains as the reference technique for morbid obesity

Overweight and obesity has more than doubled in the last 30 years, affecting people worldwide and bringing a high morbidity, mortality, and cost of treatment of obesity-related diseases[1-2]. Bariatric surgery has been the most effective way for morbidly obese patients, with a longstanding weight loss and improvement or resolution of comorbidities, which is clearly better in comparison with clinical management[3-6]. Over the last decades, there have been several technical options to treat morbid obesity surgically, and the Roux-en-Y gastric bypass (RYGB) has survived the time sieve and be considered as referral procedure.
