Gastric Sleeve Vs Gastric Banding: Choose the Right Surgery

Both gastric sleeve surgery and gastric banding surgery use restrictive techniques to provide weight loss. Both are similar in terms of expected weight loss and complication rates, but they do have significant differences.

Notable Difference

The main difference between these bariatric surgeries is whether or not the surgery is reversible. Gastric sleeve is a permanent weight loss surgery, unlike gastric banding and requires no adjustments.

Gastric Sleeve versus Gastric Banding: Table Comparison

Name: Gastric Sleeve RNY Gastric Bypass
Method of Weight Loss Restrictive Reduces Stomach Size and Hunger Hormone Ghrelin Stomach size reduced Small stomach created via implant.
Stomach Alterations Stomach size reduced 70-85% of the stomach is removed. Stomach size reduced Small stomach created via implant.
Changes to No Change No Change
Operating Time 1 Hour 2 hours
Average Hospital Stay 1 Day 2 to 3 days
Time off Work 2 weeks One week
Recovery Time 3 weeks 4-6 weeks
Pros: No intestinal changes: Less complications and side effects including dumping syndrome Hunger depressed because of reduction in Ghrelin production Life-time Approach to Obesity. Simple procedure 4-6 weeksReversible Procedure Adjustable to facilitate weight loss.Simple procedure
Disadvantages Newer surgery with long-term results somewhat unknown. Stomach Could Enlarge. Requires More Nutritional Supplements and Vitamins - Not as much as gastric bypass Lowest Expected Weight Loss of all Bariatric Surgeries. Stomach Blockage Could Happen Requires Many Physician Visits
Surgery Description Long narrow vertical pouch (about 2-3 oz or 60-100cc). Same shape as the duodenal switch pouch but smaller. No intestinal bypass. The VG significantly restricts the volume of food that can be eaten. There is a no malabsorption of nutrients or dumping. The Lap-Band is an adjustable silicone ring that is placed around the top part of the stomach creating a small (1-2 ounce or 15-30cc) pouch. Gastric Banding moderately restricts the volume and type of foods the patient is able to consume. The Band delays emptying of the pouch and creates the sensation of satiety. There is no malabsorptive of nutrients.
Realistic Expectations Patients can expect to lose 50%-60% of excess weight in about 2 years. Long term results not available at this time. Easily converted to Gastric Bypass if needed. Patients can expect to lose 50% of their excess weight. This procedure requires the most effort of all the procedures in order to be successful. Patient must be committed to good eating habits and exercise.
Post Surgery Dietary Info: Patient must eat 3 meals a day containing 600-800 calories per day (recommended for the first 24 months) and about 1000-1200 thereafter. There is no dumping or diarrhea. Patients must eat 3 meals per day consisting of less than 1000 calories per day during weight loss. Patients will need to avoid certain foods that can become "stuck" such as bread, rice, nuts, dense meats that may cause vomiting. Patients must not drink fluids with meals.
Candidate Efficacy VSG is effective for high risk or very high BMI patients. Much lower complication rate than the RNY Gastric Bypass due to there being no intestinal bypass performed. Gastric banding is most effective for patients that are more disciplined in following a strict diet and will commit to an exercise program.

Gastric Sleeve Surgery

Gastric Sleeve Surgery is also known as vertical sleeve gastrectomy (VSG). Gastric sleeve surgery can be performed laparoscopically and provides a life-time approach to weight loss. Gastric sleeve patients commonly opt to revise the surgery to duodenal switch and rny gastric bypass.

Gastric Banding Surgery

Gastric Banding Surgery is also known under the brand names: Lap-Band and REALIZE band. Often performed laparoscopically, gastric banding is a very common procedure that requires a commitment to lose weight and many physician visits.
