Roux-en-Y Gastric Bypass Surgery at Presbyterian/St. Luke's Medical Center
At the Weight Loss Surgery Center of Excellence at Presbyterian/St. Luke's Medical Center in Denver, 99% of our Roux-en-Y gastric bypass surgeries are performed using a minimally invasive surgery technique called laparoscopy.
Benefits of a Laparoscopic Gastric Bypass
- Less pain and scarring
- A shorter hospital stay
- Faster recovery and mobility
Gastric Bypass Benefits
The gastric Roux-en-Y is proven to be safe and effective surgery for people who are considered morbidly obese. 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
Gastric Bypass Procedure
The laparoscopic 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.
After Gastric Bypass Surgery
Following gastric bypass surgery, all patients have obesity-related health problems such as high blood pressure or diabetes 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.
