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.

Roux-en-Y胃旁路术仍然是治疗病态肥胖症的首选术式
