Types of Weight Loss Surgical Procedures

Several proven bariatric surgery procedures for weight loss are available at Inova Fair Oaks Hospital. Our nationally recognized and highly experienced bariatric surgeons will expertly guide you as you evaluate the weight loss surgical treatment that suits your lifestyle and overall health.


Laparoscopic gastric banding

Gastric banding is a purely restrictive surgical procedure during which a silicone band is placed around the uppermost part of the stomach, separating the stomach into one small and one large portion. The band is adjustable and can be periodically tightened or loosened depending on the patient's needs.


Gastric bypass surgery (Roux-en-Y)

Roux-en-Y gastric bypass surgery is the most common and popular bariatric surgery in the United States. The surgery involves stapling and partitioning the stomach into a small pouch and connecting the small pouch directly to the small intestine. The smaller stomach pouch restricts the amount of food the patient can comfortably eat. The bypass decreases the amount of nutrients and calories absorbed by the body.

Inova Fair Oaks Hospital specializes in mini-incision and laparoscopic gastric bypass surgery. Both of these techniques are less invasive than traditional surgery and allow for a faster, more comfortable recovery.


Sleeve gastrectomy

The sleeve gastrectomy generates weight loss by restricting the amount of food (and therefore calories) that can be eaten by removing more than 70 percent of the stomach. A smaller stomach shaped like a "sleeve" is left behind. The surgery is purely restrictive and does not involve bypassing the small intestine.


Biliopancreatic diversion with duodenal switch (BPD/DS)

BPD/DS is a combined restrictive and malabsorptive procedure that reduces the size of the stomach by 70 percent. The pouch created is a bit larger than with other restrictive procedures. The pouch is connected to the lower part of the small intestine and greatly reduces the absorption of calories and nutrients.


Risks of surgery

Weight loss surgeries are major operations on patients who often have many risk factors. Complications range from minor to major and immediate to long term. Immediate complications include leaks (1 to 4 percent, some of which would require re-operation), pulmonary emboli (blood clot to the lung), and death (1-4/1,000 patients). These risks will be reviewed by our weight loss surgeons during the free informational seminars arrow
