Gastric Sleeve
During a Gastric Sleeve procedure, a large portion of the stomach (between 65 and 85 percent) is removed and the open edges attached together with surgical staples, leaving behind a narrow tube or sleeve-like stomach. Sleeve gastrectomy is not reversible. Unlike bypass or banding procedures, sleeve gastrectomy leaves the stomach nerves and outlet valve intact, which preserves the function of the stomach. As a result, patients who undergo sleeve gastrectomy typically have fewer dietary restrictions than those who undergo other weight loss surgeries; however, because the stomach capacity is reduced to just two to five ounces, the quantity of food consumed must be significantly limited.
The following are other potential advantages of sleeve gastrectomy:
-
Because so much of the stomach is removed, the hormones that stimulate hunger are significantly decreased or eliminated.
-
Because there is no bypass of the intestines, patients avoid the potential complications associated with bypass surgeries, such as intestinal obstructions, vitamin and protein deficiencies, anemia or osteoporosis.
-
The procedure does not require the implantation of a foreign object that could cause complications or negative reactions in the body.
-
Sleeve gastrectomy may be a more suitable option for people with anemia, Crohn's disease or other complex medical conditions.
-
In most cases, sleeve gastrectomy can be performed laparoscopically (i.e., as a minimally invasive surgery).
There are some disadvantages to the procedure that you should consider: Sleeve gastrectomy is not reversible; the stomach may eventually expand, which could require another procedure; weight loss may not be as extensive as you desire (results range from 30 to 60 percent loss of excess weight); you may have to pursue other surgical options to reach your desired weight.
Surgery Risks
As with any surgery, sleeve gastrectomy has potential risks, including postoperative bleeding, pneumonia or death, though these risks are very slight. Because the procedure requires the stomach to be stapled, there is a risk of leakage or other staple-related complications.
