The Laparoscopic Sleeve Gastrectomy – often called the sleeve gastrectomy – is performed by removing approximately 80 percent of the stomach. The remaining stomach is a tubular pouch that resembles a banana.
Some Advantages and Disadvantages:
- Restricts the amount of food the stomach can hold
- Induces rapid and significant weight loss that comparative studies find similar to that of the Roux-en-Y gastric bypass.
- Requires no foreign objects to be inserted in the process, and no bypass or re-routing of the food stream (RYGB)
- Involves a relatively short hospital stay of approximately 2 days
- Causes favorable changes in gut hormones that suppress hunger, reduce appetite and improve satiety
- Is a non-reversible procedure
- Has the potential for long-term vitamin deficiencies
- Has a higher early complication rate than the AGB
