Surgery Overview

Sleeve Gastrectomy Procedure GuideThe surgery begins with multiple half-inch long incisions in the area of the stomach. The instruments are inserted through these incisions, and the surgeon begins by removing up to 85% of the stomach. The sides of the stomach are then joined by staples, leaving the stomach smaller and tubular in shape, but retaining the sphincter muscles at the top and the bottom of the stomach.

Once the surgeon determines that the staples are holding the stomach closed and no areas are leaking, the instruments are withdrawn and the incisions are closed, typically absorbable sutures and sterile tape.

What to expect

After surgery, you may need pain medicine to help with the discomfort and soreness. You will be encouraged to move around to help your body heal. For the first 2 weeks, your stomach can only handle small amount of liquids while you are healing. It is common to notice that bowel movements will not be regular after surgery. Try to avoid constipation and straining with bowel movements.

Please call your doctor if you have:

  • Dizziness
  • Shortness of breath
  • Rapid pulse
  • Minimal or no urine production
  • Worsening abdominal pain
  • Fever
  • Vomiting
  • Pus or any type of abnormal discharge from wound
  • Red and warm with thickening of the skin in the incision areas
