Sleeve gastrectomy

Sleeve gastrectomy (stomach reduction) is keyhole surgery in which about 60-85% of the stomach is removed to combat obesity. This creates a narrow gastric tube of about 100 to 150 cc.

So of the original stomach (size of a melon), a stomach remains with the size of a banana. A stomach reduction allows less food to be absorbed. It also removes the part of the stomach that triggers hunger (ghrelin). As a result, you feel less hungry.

• Volume eaters who do not have reflux or hiatal hernia
• Extremely obese patients, as a first surgical step to prepare for a gastric bypass. The advantage of sleeve gastrectomy over a gastric bypass is that it cannot cause dumping. Dumping is a side effect after gastric surgery when food passes too quickly from the stomach to the intestines. Dumping can lead to uncomfortable symptoms (nausea, abdominal cramps). A sleeve is not reversible.
  

The most important risks are:

• staple-line leaks
• abscess
• bleeding
• vitamin deficiencies (long-term)
• weight may go up again if you maintain an unhealthy lifestyle after surgery

After 12 months, an average weight loss of up to 30% is expected.
