Abstract

Laparoscopic Roux-en-Y gastric bypass (LRYGB) has been performed for the treatment of obesity for several decades now, and is regarded as the gold-standard operation to which all the newer procedures should be compared. The reasons for the popularity and longevity of LRYGB include durable long-term weight loss and comorbidity resolution outcomes at an acceptable risk. In this chapter, we discuss the weight loss outcomes of LRYGB and the comparison of these with other commonly performed bariatric procedures, such as laparoscopic gastric banding, sleeve gastrectomy, one-anastomosis gastric bypass, and duodenal switch. The impact of technical and patient variables on weight loss outcomes is explored. Among the technical variables, pouch and stoma size, anastomotic technique, limb length, and the use of banded bypass are discussed. The possible reasons for unsatisfactory weight loss or weight regain are also discussed, along with revisional surgery options currently being explored for these patients.
