Dr. Williams will be performing the following weight loss procedures at Parkwest Medical Center:

  • Biliary Pancreatic Diversion: With this procedure portions of the stomach are removed. The small pouch that remains is connected directly to the final segment of the small intestine, completely bypassing the upper part of the small intestines.  Weight loss occurs since most of the calories and nutrients are routed into the colon where they are not absorbed.
  • Laparoscopic Adjustable Gastric Banding (LAGB): This is a laparoscopic procedure with small incisions in the upper abdomen. The surgeon puts an adjustable band around the top part of the stomach. This creates a very small stomach pouch. The small stomach pouch means that you’ll feel full after eating less food. The band is adjustable.
  • Gastric sleeve (laparoscopic sleeve gastrectomy): this type of procedure permanently reduces the stomach to the size of and shape of a banana, which restricts the amount of food that can be eaten. Patients lose weight by eating fewer calories. This procedure also impacts the production of ghrelin.
  • Gastric bypass (laparoscopic Roux-en Y): considered the gold standard for weight loss surgery, this procedure reduces the stomach through stapling and “bypasses” the large intestines, which results in less calorie absorption and creates a sense of satisfaction with less food. The surgery results in less production of ghrelin, a hormone that may be partly responsible for making you feel hungry.
