Roux-en-Y Gastric Bypass Surgery

Gastric Bypass Surgery, Denver

Gastric bypass surgery involves creating a small pouch from your stomach. This pouch is attached to a small piece of intestine so food can come out of the pouch directly into a segment of the small intestine, allowing a part of the stomach and small intestine to be bypassed. Weight loss is induced because the pouch restricts the amount of food and then bypassing the stomach and duodenum restricts calorie absorption, while still allowing adequate nutrition. It is very important, however, for patients to change eating habits to include restricted portions of food and make food choices that optimize nutrition.

After gastric bypass surgery, all patients have obesity-related co-morbities improve or resolve completely. Weight loss is first dramatic-- average weight loss is 90 lbs at 6 months and 117 lbs at 1 year. If patients follow lifestyle and dietary changes, weight loss can continue for up to 18 months.

This procedure can now be done laparoscopically and is proven safe and effectivein morbidly obese patients.

The gastric Roux-en-Y is proven to be safe and effective in morbidly obese patients.  It allows patients to:

  • Lose significant weight and maintain weight loss long-term
  • Reverse many obesity-related health problems
  • Increase longevity and quality of life

About Gastric Bypass

Laparoscopic Roux-en-Y gastric bypass procedure combines restrictive and malabsorptive procedures.

  • Laparoscopy is a long tube with a small camera lens at one end. It is connected by fiber optics to a camera at the other end. Surgeons create several small incisions through which instruments are passed to perform the procedure.
  • When the upper portion of the stomach is freed, a row of staples is placed horizontally, just below the intersection of the esophagus and stomach.
  • The tiny pouch at the top of the stomach is about one to two ounces in size and is totally separated from the rest of the stomach.
  • The small bowel (jejunum) is  attached to the stomach pouch, which creates a food channel. The duodenum and first part of the jejunum are separated from this portion of the food channel.
  • The upper small bowel (the duodenum, bile, and pancreas) is attached to the side of the food channel forming a Y-shape.
  • A surgical connection/ anastamosis is performed to secure the stomach pouch.
  • The Gastric Bypass procedure restricts food intake because of the small size of the stomach, and also leads to poor absorption of food now that the bile and pancreatic secretions come into contact with food well beyond the stomach.
