Laparoscopic sleeve gastrectomy is a nonreversible weight-loss procedure that reduces stomach size by 85 percent, generating weight loss solely through reduced food intake.
Benefits
Studies have shown that patients who undergo laparoscopic sleeve gastrectomy lose 55 to 65 percent of excess weight within one year. The surgery can reduce cravings for sweets and improve your overall quality of life. Because it is a minimally invasive surgery, the procedure will require a shorter hospital stay and result in a faster recovery time.
Before Surgery
Your cardiovascular, pulmonary and endocrine systems must be evaluated before you undergo sleeve gastrectomy surgery. Also, a psychological evaluation is necessary to help determine your response to dramatic weight loss and a new body image. You will also speak with a care team member about dietary/nutritional issues related to your surgery.
During Surgery
During surgery, the stomach is divided vertically. The portion of the stomach that remains is shaped like a very slim banana or sleeve which measures from 1 to 5 ounces.
There is no intestinal bypass, only stomach reduction. The lack of an intestinal bypass reduces the risk of potential long-term complications such as marginal ulcers, vitamin deficiencies and intestinal obstructions.
After Surgery
Like with the traditional gastric bypass procedure, you will be able to limit the amount of food you eat at one time after laparoscopic sleeve gastrectomy because smaller portions will satisfy you. You will need to make other changes to your overall diet and eating habits, including drinking at least eight cups of water per day and chewing your food completely.
