Gastric Bypass Surgery in Denver
At CBSI, 99% of our Roux-en-Ys are performed laparoscopically, allowing patients less pain and scarring, a reduced hospital stay, and faster recovery and mobility. And now, the majority of the gastric bypasses are being done robotically.
During gastric bypass surgery, a small pouch from your stomach is created. A piece of small intestine is attached to the pouch so food can come out of the pouch directly into a segment of small intestine, thereby causing a part of the stomach and small intestine to be bypassed. The mechanism of weight loss is two-fold: the small pouch restricts the amount of food, while the bypass of the stomach and duodenum restricts the body’s ability to absorb calories, while still providing adequate nutrition. As a result of the surgery, changes in eating habits are required. These included restricted portions of food, as well as food choices that optimize nutritional requirements.
Following gastric bypass surgery, all patients have obesity-related co-morbidities that improve or resolve completely. Weight loss is initially dramatic with an average weight loss of 90 lbs at 6 months and 117 lbs at 1 year, and weight loss can be anticipated for up to 18 months if patients are compliant with the lifestyle and dietary changes required.
The gastric Roux-en-Y is proven to be safe and effective in morbidly obese patients. The gastric bypass allows these patients to:
- Lose significant weight and maintain weight loss long-term
- Reverse many obesity-related health problems
- Favorably impact longevity and quality of life
Brief Description of the Gastric Bypass
The Roux-en-Y gastric bypass procedure is a combination of a restrictive and malabsorptive procedure.
- A laparoscopy is a long tube with a small camera lens at one end connected by fiber optics to a television camera at the other end. Several small incisions are made through which instruments are passed to conduct the procedure.
- The upper portion of the stomach is freed and a row of staples is placed horizontally (side to side) a few centimeters below the esophagus–stomach junction.
- A tiny pouch is created at the top of the stomach and is about 1-2 ounces in size. The pouch is totally separated from the rest of the stomach.
- The small bowel (jejunum) is brought up and attached to the stomach pouch, establishing a food channel. The duodenum and first part of the jejunum are separated from this portion of the food channel.
- The upper small bowel which contains the duodenum, bile, and pancreas is attached to the side of the food channel forming a Y-shaped arrangement of the bowel.
- A surgical anastamosis/connection is performed to precisely and accurately secure the stomach pouch.
The procedure results in restricted food intake because of the small size of the stomach pouch and poor absorption of food, because now the bile and pancreatic secretions come into contact with food well beyond the stomach.
