Vertical gastrectomy / sleeve gastrectomy

The Vertical Gastrectomy is also known as the Sleeve Gastrectomy, Restrictive Vertical Gastroplasty, or Vertical Sleeve Gastrectomy. The Vertical Gastretomy is essentially a newer, better version of the vertical banded gastroplasty, a procedure that has been abandoned by virtually all weight loss surgeons, due to high failure rates and complications.

LAP-BAND® System, adjustable gastric band

The LAP-BAND adjustable band is placed laparoscopically around the upper part of the stomach. The silicone band divides the stomach into a small pouch above the band and larger pouch below the band. The smaller pouch limits the amount of food the patient can eat with the result of fullness after eating a small amount of food. The band is connected by a tube to a port that is placed underneath the skin and fat of the abdominal wall on top of the muscle. [Learn More about LAP-BAND®]

Roux-en-Y gastric bypass

Most common weight loss surgery performed in the U.S. and considered the gold standard of weight loss surgery. Dr. Feng creates a small, upper stomach pouch about 1 ounce in size, dividing it from the lower stomach. This significantly restricts the volume of food that can be eaten. He then divides the small intestine to create a Y-shaped section to attach to the stomach pouch. [Learn More Roux-en-Y Gastric Bypass ]

Duodenal Switch

This procedure offers the ability to eat larger portions foods than gastric bypass or adjustable gastric banding and has reliable and long lasting weight loss. You may experience more bowel movements and need to closely monitor your vitamin, protein and mineral levels. [Learn More Duodenal Switch weight loss surgery]
