A Restrictive Procedure

The sleeve gastrectomy is an operation in which the left side of the stomach is surgically removed, leaving it roughly the size and shape of a banana.  The nerves to the stomach and the outlet valve remain intact to preserve the functions of the stomach while drastically reducing its volume.

By comparison, when a gastric bypass (Roux-en-Y) procedure is performed, the stomach is divided rather than removed and it can be reconnected (reversed) if necessary.  There is no intestinal bypass with sleeve gastrectomy procedures, only stomach reduction.

Advantages

  • Sleeve gastrectomy involves no malabsorption of nutrients, therefore avoiding anemia, osteoporosis, protein deficiency and vitamin deficiency
  • This is the only surgery that substantially removes the "hunger hormone," ghrelin.
  • No adjustments or fills are needed.
  • The chances of an ulcer occurring are minimized.

Risks

  • This procedure involves stomach stapling. Therefore, leaks and other complications related to stapling may occur.
  • Because the stomach is removed, it is not reversible. It can be converted to almost any other weight loss procedure.
  • The smaller, remaining portion of the stomach may stretch.
  • Foods that you eat now may cause discomfort, nausea or vomiting after your surgery.
  • Gastric surgery puts you at higher than normal risk of developing gallstones and gallbladder disease.
