Sleeve gastrectomy is a relatively new bariatric operation, and currently comprises 10-20 percent of bariatric operations performed in the US: This number is expected to rise in coming years. Sleeve gastrectomy is a safe and effective operation. Your surgeon will help you decide if this is the right operation for you.
How does it work?
Sleeve gastrectomy involves removal of the majority of the stomach, leaving a narrow "sleeve" of stomach that limits food intake much like a gastric pouch, but without the need to rearrange intestinal anatomy. Sleeve gastrectomy thus restricts the amount of food a person can eat and provides a feeling of fullness.
What are the risks?
Sleeve gastrectomy is a simpler operation than gastric bypass, but unlike banding, requires removal of a majoirty of the stomach and is thus irreversible. No intestines are cut, removed or bypassed. Because of this, vitamin or mineral deficiencies are rare after sleeve gastrectomy. Rare complications include bleeding and infection. Serious complications or death are rare, less than gastric bypass but greater than gastric banding.
Late complications (usually months or years after surgery) are expected to be rare after sleeve gastrectomy, in part because no rearrangement of the intestine is involved. These include hernias, development of heartburnand rarely, excessive narrowing of the sleeve due to scarring during healing.
What are the benefits?
Weight loss after sleeve gastrectomy ranges from 50-60 percent of excess weight in most patients, similar to gastric bypass. More than 80 percent of patients will experience marked improvement in related diseases such as diabetes, sleep apnea, high blood pressure, fatty liver disease, osteoarthritis, and other diseases.
