Weight Loss Surgery Comparison

Weight Loss Surgery Comparison

The National Institutes of Health Consensus Development Panel established general guidelines and indications for bariatric surgery in 1991.1 Weight loss surgeries are well established and have been performed for more than 25 years. The most common forms of bariatric surgery are laparoscopic gastric band, laparoscopic gastric sleeve, and laparoscopic gastric bypass. All three of these procedures are offered at West Georgia Health. These procedures are performed using minimally invasive (laparoscopic) techniques. Minimally invasive means faster operations, less anesthesia, much smaller incisions and less scarring, all of which contribute to faster healing and recovery.

Weight Loss Surgery Comparison

When comparing the different types of weight loss surgery, one must weigh the benefits and risks to determine which procedure is best for you. The following is an assessment of various weight loss surgeries and their characteristics:

Gastric Bypass

Procedure:

A small stomach pouch is created and the small intestine is re-routed and attached directly to the pouch.

Goals & Outcomes:

70-80 percent of excess weight loss, 79% remission from hypertension, 66% remission from hyperlipidemia, and 66% remission from obstructive sleep apnea within the 1st year.2

Diet Changes:

Must avoid sugar and fats to prevent “dumping syndrome.” Has a more complex multi vitamin and mineral regimen due to malabsorption.

Potential Risks:

  • Anemia
  • Bowel obstruction
  • Dumping syndrome
  • Leaks
  • Ulcers
  • Osteoporosis
  • Vitamin/mineral deficiencies
  • Vomiting

Average Hospital Stay:

2 days.

Gastric Sleeve

Procedure:

A thin vertical sleeve of the stomach is created, which is approximately the size of a banana. The stomach is restricted by stapling and dividing it, removing approximately 80%.

Goals & Outcomes:

60-70 percent of excess weight loss, 68% remission from hypertension, 35% remission from hyperlipidemia, and 62% remission from obstructive sleep apnea within the 1st year.2

Diet Changes:

Allows for the most “normal” eating with few food intolerances. Relatively safe option for “ill” or older patients with pre-existing complications. Has a lower complication rate due to the simplicity of the surgery.

Potential Risks:

  • Nausea
  • Vomiting
  • Heartburn
  • Leaks

Average Hospital Stay:

Average Hospital Stay:

Gastric Band

Procedure:

A gastric band is placed on the upper portion of the stomach, creating a smaller upper pouch. The tightness of the band affects how
much food you can eat.

Goals & Outcomes:

40-50 percent of excess weight loss at one year. Gastric Band is reversible or can be altered to another bariatric surgery in the future, if desired.

Diet Changes:

Must avoid certain foods that can get “stuck” if eaten
including rice, bread, dense meats, nuts, and popcorn, as these can cause pain and vomiting. Can’t drink fluids during meals.

Potential Risks:

  • Slower weight loss
  • Band slippage
  • Band Erosion
  • Infection
  • Port problems
  • Device malfunction

Average Hospital Stay:

1 day.
