  Gastric Banding Surgery

The Ohio State University Bariatric Surgery Program offers three types of bariatric procedures.

Roux-en-Y Gastric Bypass

Through this procedure, a one-half to one ounce pouch about the size of an egg is made from the stomach. The pouch is connected to the rest of the gastrointestinal tract, changing the pathway of the small intestine.

Benefits:

  • Results in greater weight loss – patients lose about 60-85 percent of excess weight in 12-18 months as compared to the gastric banding procedure
  • Better long-term success – patients typically regain less than 15 percent of their weight after five-10 years
  • Small incisions and faster recovery – this is a result of minimally invasive surgery techniques

Risks:

  • Leakage through staples or sutures that hold stomach and intestine together
  • Injury to the spleen during surgery
  • Ulcers can develop in the stomach or small intestine
  • Blockage of stomach opening
  • Possible swelling of esophagus, making it difficult to swallow foods and liquids
  • Possible dilation of esophagus, causing a reduced feeling of fullness after eating
  • Vitamin and iron deficiency

Gastric Banding

This surgical procedure places an adjustable band around the upper stomach. Once in place, the band is inflated with saline through a small port, creating a small stomach pouch that limits food consumption and creates a feeling of fullness.

Benefits:

  • Adjustable and reversible
  • Tailored to meet patient's specific needs
  • Small incisions and faster recovery as a result of minimally invasive surgery techniques
  • Loss of about 50 percent of excess weight over three-five years
  • Outpatient or overnight stay

Risks:

  • Infection at port where band adjustments are made
  • Band may slip out of place 
  • Band may wear at stomach tissue

Sleeve Gastrectomy

A sleeve gastrectomy is a restrictive surgical weight loss procedure that limits the amount of food you can eat and helps you feel full sooner. In this procedure, a thin, vertical sleeve of stomach is created and the rest of the stomach is removed. The sleeve is about the size of a banana.


Benefits:

  • No malabsorption (does not create the inability to absorb certain sugars, fats, proteins, or vitamins from food)
  • Patients lose about 60% of their excess weight by 18 months after surgery

Risks:

  • Leak in the suture line
  • Vitamin B12 deficiency
  • May require a second surgery
