The Laparoscopic gastric bypass with Roux en Y limb over the past decade has become the "Gold Standard" surgical procedure in bariatric surgery.  Many surgeons will clearly identify this bariatric procedure as the bariatric procedure with the best ratio of weight loss versus long term side effects.

Since surgical teams in the United States have begun to perform this procedure via minimally invasive means or laparoscopy in the mid-nineties, it has dramatically grown in popularity. Patient undergoing this procedure in expert bariatric surgical services or Bariatric Center of Excellence will undergo this procedure via laparoscopy with negligible risks of being converted to an open procedure or a laparotomy. Thus, recovery after this procedure is prompt and only require an average of a one day hospital stay or a "23 hours stay".
