| Pros | Cons |
| Does not require the implantation of a foreign body, such as a silastic ring used in gastric banding. | Potentially slower weight loss than Roux-en-Y Gastric Bypass or Duodenal Switch. |
| The procedure both mechanically decreases the size of the stomach and also decreases the secretion of the hormone, ghrelin, which is responsible for the feeling of satiety (fullness) (the procedure removes part of the stomach that produces this hormone). | Not as much clinical data available (when compared to gastric bypass and adjustable gastric banding). |
| There is no malabsorption. Less vitamin or mineral deficiencies deficiencies when compared to gastric bypass. | Potential for gastric leaks (due to stapled resection of the stomach). |
| There are no anastomoses or rerouting of the intestinal tract. | |
| Less long-term maintenance than gastric banding (no band fills needed). | |
| More weight loss than Adjustable Gastic Banding.1Can offer the benefit of initially decreasing body weight in the severely obese patient, to prepare him/her for another surgery at a later time. |
