Some of the common types of Medicare bariatric surgeries include gastric bypass, lap band surgery and gastric sleeve surgery.
Gastric bypass surgery
This common malabsorptive weight loss surgery is also known as Roux-en-Y gastric bypass (RYGB). In this procedure, a small stomach pouch is created to restrict food intake. The rest of the stomach is bypassed via a Y-shaped segment of the small intestine, which reduces the amount of calories and nutrients the body absorbs.
LAP-BAND® surgery
This surgery is defined as “Laparoscopic adjustable gastric banding (LAGB) (i.e., LAP-BAND®).” This common weight loss procedure involves the placement of a hollow band around the upper end of the stomach, creating a small pouch and a narrow passage into the larger remainder of the stomach. The band is inflated with saline solution, which can be increased or decreased over time to alter the size of the passage.
Gastric sleeve surgery
This weight loss surgery is also commonly known as “vertical sleeve gastrectomy” or “sleeve gastrectomy” (open or laparoscopic). This procedure involves the removal of the greater curvature of the stomach and approximately 80% of the stomach volume. While pyloric sphincter and stomach functions are preserved, the remaining stomach resembles a slender curved tube.
