Types of Bariatric Procedures We Offer

Sleeve Gastrectomy

Sleeve Gastrectomy is a laparoscopic surgical procedure in which the stomach is remodeled into a long tube about one-quarter the size of the original stomach. During the procedure, staples are placed across the stomach to create the new smaller reservoir, permanently dividing the stomach. A portion of the stomach is removed. Fewer calories are absorbed as your stomach is now restricted in size. The procedure permanently reduces the size of the stomach. This is not a reversible procedure.

Gastric Bypass

The gastric bypass incorporates both a restrictive and malabsorptive components of bariatric surgery. The Roux-en-Y bariatric procedure is restrictive as it involves reducing the size of the stomach, usually using staples, to create a small pouch which becomes completely separate from the remainder of the stomach.

Revisional Surgeries

The most common reason patients consider bariatric revisional procedures is weight related, either not enough weight was lost following surgery or too much was gained back. The stomach or the connection between the stomach pouch and the small intestine can slowly increase if there is weight gain after initial weight loss surgery. Some bariatric revisional procedures do not require large open incisions and can effectively reestablish the full benefits of their previous weight loss surgery.

Gastric Band

The laparoscopic adjustable gastric banding procedure is a procedure in which a small gastric pouch is created by placing an adjustable gastric band around the top of the stomach.

This band is inflatable via an access port that is imbedded under the skin. This allows the band to be adjusted to meet individual patient needs. As a result, the amount of food a patient can eat is limited, creating an earlier feeling of fullness.
