Sleeve Gastrectomy - Banded And Conventional

What Is It?

The vertical sleeve gastrectomy, or sleeve gastrectomy, is a type of restrictive weight loss surgery. It causes weight loss by restricting the amount of food that a person can consume before feeling full.

How is it performed?

Conventional Sleeve Gastrectomy is a surgical procedure that can be performed by minimally invasive surgery (Laparoscopically or robotically). The procedure reduces the size of the stomach to about 10% of its original volume and results in a limited capacity of food intake. In sleeve gastrectomy, the left side of the stomach is surgically removed by cutting and stapling. This results in a new stomach which is roughly the size and shape of a banana.

Who can undergo this procedure?

The surgery is typically performed on patients who are too heavy to have other types of weight loss surgeries with the expectation that a second surgery will be performed once weight has been lost, or on individuals who do not suffer from severe co morbidities and are young.

Advantages

It does not require disconnecting or reconnecting the intestines

  • It is technically a simpler operation than gastric bypass
  • It may be used as the first stage of a 2-stage operation.
  • The operation eliminates the portion of stomach (fundus) that produces the hormone ghrelin which stimulates hunger.
  • Vitamin and mineral supplementation maybe needed for a shorter duration as compared to gastric bypass.

Disadvantages

  • Possibility of weight gain after a few years due to stretching of stomach muscles.
  • Possible late dilatation of stomach pouch
  • Leaks from the staple line of the newly formed stomach (1 in 1000 people)

What is a Banded Sleeve Gastrectomy?

A silastic (GaBP) ring of 7.5 cm diameter is wrapped around the upper part of the sleeve. Adding a silastic band to sleeve gastrectomy increases the success rate by preventing gastric tube dilatation. This allows in maintenance of weight loss in the long term.
