Sleeve gastrectomy (or gastric sleeve) is a restrictive procedure where the stomach is reduced to about the size of a banana using a large number of staples, and the larger part of the stomach is removed. The smaller stomach restricts or limits the amount of food you can eat but allows for normal digestion and absorption of nutrients. Sleeve gastrectomy is permanent. The procedures was originally developed as a two part treatment where the patient first has sleeve gastrectomy and once their weight reached a certain level, a second treatment such as gastric bypass was performed. In these cases, sleeve gastrectomy was designed for patients with a Body Mass Index (BMI) of 60 or higher.
The Lap Band procedure, on the other hand, involves no cutting or stapling of the stomach or intestinal rerouting, it is adjustable and reversible and designed for sustained weight-loss. The Lap Band procedure is a restrictive procedure during which an adjustable gastric band is placed around the upper part of the stomach. This creates a smaller stomach pouch, which restricts the amount of food that can be consumed at one time and helps the patient to feel full sooner. As a result, patients achieve sustained weight-loss by limiting food intake and reducing appetite while allowing for the normal absorption of nutrients.15
Compared to Lap Band
The Lap Band is a restrictive device and requires no cutting, stapling, or removal of any part of your existing stomach. Instead, the Lap Band is placed around the stomach to limit the amount of food it can hold at one time.
Similar to gastric bypass, sleeve gastrectomy (or gastric sleeve) requires stomach cutting and stapling to create a small sleeve-shaped stomach, about the size of a banana — the larger part of the stomach is permanently removed.
The Lap Band can be quickly, easily and non-surgically adjusted to affect weight-loss results — during a brief doctor’s office visit. Since such a large part of the stomach is removed during the gastric sleeve procedure, there are not really any “adjustments” to be made.
While the Lap Band is a long-term weight-loss solution, if necessary, the procedure can be reversed — with the stomach returning to its original shape. Due to stomach cutting and removal, the gastric sleeve procedure is considered permanent and cannot be reversed. It is typically performed as part of a two-part procedure where the second treatment can be gastric bypass, which is also permanent.
Lap Band is the only gastric banding system with a nine-year safety history — FDA approved since 2001. There is currently no long-term safety data in the U.S. on sleeve gastrectomy.
The Lap Band procedure has been proven in studies to significantly reduce weight and body mass steadily and consistently with patients maintaining their weight-loss over time.1,16 Weight-loss with the Lap Band was shown in one study to resolve (76%) or improve (14%) gastroesophageal reflux (N=48).4 Results are expected to be similar to gastric bypass, which may result in some weight gain. Typically long-term weight-loss results are comparable to adjustable gastric banding.17
No risk of staple-line leakage, as there is no cutting or stapling of the stomach with the Lap Band procedure.
- Mortality rate: 0.05%19
- Total complications: 9%20
- Major complications: 0.2%20
Most common complications include:
- Standard risks associated with major surgery
- Nausea and vomiting21
- Lap Band slippage
- Stoma obstruction
- In clinical studies, there have been no reported risks for renal failure after the Lap Band procedure.
With sleeve gastrectomy, there is a risk of possible staple-line leakage, which may require additional surgery to resolve. There is also a risk of gastric reflux and esophagitis.18
- Mortality rate: <1%18
- Major complications: 2.9%18
- gastric remnant dilation
- suture line bleeding and leakage
- gastric strictures22
- There is a risk of renal failure after having the gastric sleeve procedure.20

The LAP BAND System was approved in the United States on the basis of a nonrandomized, single-arm study (N=299). Significant improvement in percent of excess weight-loss vs. baseline was achieved at 12 months (34.5%), 24 months (37.8%), and 36 months (36.2%).
