Hear first-hand from a LAP-BAND® Surgery Patient 
 


The laparoscopic adjustable gastric banding surgery is an innovative, safe and effective surgical intervention for people who have failed more conservative weight reduction alternatives, such as supervised diet, drugs, exercise and behavior modification programs. 

Sentara offers two alternatives for gastric banding surgery: LAP-BAND® system and REALIZE® band. In both cases, a band is placed around the uppermost part of the stomach to divide the stomach into two portions: one small and one larger portion. Since the stomach is divided into smaller parts, most patients feel full faster. Food digestion happens through the normal digestion process when food gradually passes through the narrow channel to the lower stomach and into the intestine for digestion.

The band is adjustable by injecting or withdrawing fluid (saline) from an access port under the skin.  An adjustment is made if the band is too loose and patients are not losing adequate weight or if it is too tight causing vomiting. An adjustment can only be performed at a surgeon's office.

In gastric banding surgery, the band is normally left in place for the rest of the person's life. Removal requires another surgery and is only performed if there are severe side effects or complications. Weight gain is expected if the band is removed.

Advantages of the Laparoscopic Gastric Banding Surgery

Average best weight loss for laparoscopic adjustable gastric band is 55 percent to 65 percent.
Since there is no cutting, stapling or intestinal re-routing involved in laparoscopic adjustable gastric banding surgery, it is considered the safest and least traumatic compared to other weight loss surgeries.
The band is adjustable, removable and does not permanently alter the anatomy.
Significantly lower mortality risk than with other obesity surgeries. 
Low risk of nutritional deficiencies associated with gastric bypass.
Reduced risk of hair loss.
No dumping syndrome related to dietary intake restrictions. A condition known as dumping syndrome can occur from eating too much sugar or large amounts of food in gastric bypass patients.
Supports pregnancy by allowing stomach outlet size to be opened for increased nutritional needs.
Lower operative complication rate than gastric bypass.
Low malnutrition risk.

Risks and Disadvantages of the Laparoscopic Gastric Banding Surgery

The access port may leak or twist, which can require an operation to correct the problem.
Surgery may not provide the necessary feeling of satisfaction that one has had enough to eat.
Dumping syndrome, which may provide important warning signs, does not occur. 
Band may erode into the stomach wall.
Band may move or slip.
Weight loss is slower than that following Roux-en-Y gastric bypass surgery. Average best weight loss for patients undergoing laparoscopic gastric bypass is 75 percent versus 55 percent to 65 percent for laparoscopic adjustable gastric banding surgery.
A certain amount of risk exists with any operation, and the risk is increased with patients who have had previous surgery of the stomach.
Wound infections can occur, leaks of the new pouch or at the sites of the intestinal connection are unlikely, but can happen.
Blood clots to the lungs can happen as with any operation, but are very rare.
Peptic ulcerations can occur. 
The procedure could result in death.
