Laparoscopic Roux-en-Y gastric bypass

Laparoscopic Roux-en-Y gastric bypass (LRYGB), as a bariatric procedure, was first described by Alan Wittgrove in 1994 [1]. Over the ensuing decades, the technique of LRYGB as well as perioperative care of patients have been gradually improved and refined [2]. Consequently, the mortality rate associated with the RYGB has decreased from 2.6 percent at the turn of the century [3] to 0.12 percent in contemporary practices [4].

LRYGB has been established as the gold standard against which other bariatric procedures are measured. LRYGB induces more weight loss than adjustable gastric banding [5] and more durable weight loss than sleeve gastrectomy [6], causes lower morbidity and mortality than biliopancreatic diversion/duodenal switch [7], and has proven efficacy that is unparalleled by newer procedures such as mini-gastric bypass, single-anastomosis duodenal switch, intragastric balloon, and vagal stimulation [8-10].

The indications, preoperative workup, techniques, postoperative care, and outcomes of LRYGB are discussed here. Other bariatric procedures and perioperative management of bariatric patients in general are discussed in other topics, including:

(See "Bariatric operations for management of obesity: Indications and preoperative preparation".)
