ABSTRACT

Surgeons will argue the superiority of GBP versus VBG and vice versa. VBG does not produce as much excess weight loss as the GBR nor is it as durable. VBG does produce adequate weight loss improving the patient s obesity comorbidities. VBG is technically simpler to perform, offers less risk of micronutritional deficiencies, and maintains the continuity of the gastrointestinal tract. Furthermore, the VBG is considered a less morbid procedure, though some will argue to the contrary. The major disadvantage is that patients can regain the weight lost with the VBG by simple alterations in their diet. Foods that are high in fat and carbohydrates while low in volume are the main culprits. These same foods tend to cause a dumping syndrome in GBP patients and “protect” them from regaining unwanted weight. Overall, the choice between which procedure to perform depends on the surgeons experience and comfort with the procedure.
