The sleeve gastrectomy (gastric sleeve) decreases hunger and meal size by reducing the size of the stomach. Originally used as the first stage of a gastric bypass procedure, it has become popular because a proportion of people maintain weight loss without needing to proceed to a gastric bypass—the smaller size of the stomach is often enough to assist with weight loss.

Because no band is required, there is no need for ongoing adjustments following a sleeve gastrectomy, although as with all bariatric surgery the results are more predictable when a regular follow-up program is in place. Because part of the stomach is removed, the sleeve gastrectomy is not reversible. It does, however, have a lower complication rate than gastric bypass surgery in most patients.

Sleeve Gastrectomy (also known as Gastric Sleeve surgery) is a relatively new approach to weight loss surgery. With Gastric Sleeve, using a small stapling device, around two thirds of the stomach is removed laparoscopically, via a small tube.

How does Gastric Banding compare to Gastric Sleeve (Sleeve Gastrectomy)?

Procedural Differences

GASTRIC BANDING

The adjustable Gastric Banding Procedure uses a restrictive device and requires no cutting, stapling or removal of any part of the stomach. Instead, a band is placed around the stomach to limit the amount of food it can hold.

SLEEVE GASTRECTOMY

Requires stomach cutting and stapling to create a small sleeve shaped stomach, about the size of a banana. The larger part of the stomach (around two-thirds) is permanently removed.

Is the procedure adjustable?

GASTRIC BANDING

Gastric Banding can be quickly, easily and non-surgically adjusted to affect weight loss results during a brief visit to the doctor’s office.

SLEEVE GASTRECTOMY

Adjustment is not possible.

Is the procedure reversible?

GASTRIC BANDING

Adjustable Gastric Banding can be reversed with the stomach returning to its original shape.

SLEEVE GASTRECTOMY

Due to stomach cutting and removal this procedure is considered permanent and cannot be reversed.

Are the results long term?

GASTRIC BANDING

Complications can include:

  • Acid reflux and vomiting
  • Band slippage
  • Stoma obstruction
Mortality rate: 0.05%
Total complications: 9%
Major complications: 0.2%

SLEEVE GASTRECTOMY

Complications can include:

  • Gastric remnant dilation
  • Risk of possible staple-line leakage
  • Suture line bleeding, leakage and gastric strictures
  • Risk of gastric reflux
Mortality rate: <1%
Major complications: 2.9%
