Gastric Sleeve Section (reduced stomach area)
Surgically removed stomach section
The gastric sleeve surgery, also known as the vertical sleeve gastrectomy is a restrictive weight loss surgery procedure. During surgery, about 85% of the existing stomach is removed leaving a portion of the stomach that is about the size and shape of a banana, or sleeve. The new capacity of the stomach ranges from about 60 to 150 cc, depending on the surgeon’s final estimation. The outlet valves and nerves to the stomach are left intact meaning that stomach function is not compromised despite the procedure.
The vertical sleeve gastrectomy does not offer as significant a weight loss as gastric bypass. Indeed there is a possibility of weight regain after surgery. Staple leakage is a very serious complication that could require hospitalization. As with any major surgery, additional risks can include post-operative bleeding, small bowel obstruction, pneumonia and even death.
Surgery for Extremely Obese Patients: For patients with extreme BMIs, the gastric sleeve surgery is a relatively easier procedure to perform. As a result, the sleeve can be performed as both a standalone procedure and the first of a two part process.
For obese patients with a relatively lower BMI, the vertical sleeve gastrectomy is preferred, especially when conditions such as anaemia or Crohn’s disease prevent other bariatric procedures from being performed.
Patients may prefer this surgery if they are concerned about the long-term effects of bypass surgery or if they do not want a foreign object in their body as in Lap Band surgery.
