Gastric Sleeve

What is Gastric Sleeve?

Sleeve Gastrectomy, also known as gastric sleeve, is a restrictive procedure surgery. Gastric Sleeve permanently reduces the size of the stomach. By creating a smaller stomach, the stomach will fill more quickly, and the patient will feel satisfied from eating much less food. This procedure can often be performed laparoscopically, using several small incisions.

Gastric Sleeve

During the procedure, the surgeon uses staples to divide the stomach vertically and remove 60-80% of it. The remaining stomach is roughly the size and shape of a banana. Because a large portion of the stomach is removed, gastric sleeve is not reversible. The nerves to the stomach and the outlet valve remain intact to preserve the functions of the stomach while drastically reducing its size. If weight loss is insufficient following a sleeve gastrectomy, another surgery can be performed, such as gastric bypass.

Originally, gastric sleeve surgery was designed to be followed up by a second bariatric procedure, such as gastric bypass, in patients who could not tolerate a combined weight loss surgery. Recently, gastric sleeve surgery is used as a stand-alone weight loss procedure. Because stomach function remains mostly intact, and because the intestine is not bypassed, this procedure has fewer side effects than gastric bypass. Patients are less likely to experience dumping syndrome or malnutrition.

Advantages/Disadvantages

Advantages:

  • It restricts the amount of food that you can eat
  • Digestion and absorption are normal – the digestive tract is not changed in any way
  • There are no needed “adjustments” after surgery
  • Resolution of some co-morbid conditions, such as: Type II diabetes, hypertension, hyperlipidemia and sleep apnea
  • Patients can lose between 60-75% of their excess body weight

Disadvantages:

  • Complication due to stomach stapling, including separation of tissue that was stapled and leaks form the staple line
  • This is a non-reversible procedure, since a large part of the stomach is removed
  • Nausea or the inability to eat certain foods
  • Vomiting may occur from eating more than your stomach can hold
  • Heartburn or “reflux”
