Gastric Bypass

Roux-en-Y gastric bypass is the most frequently performed weight-loss surgical procedure. In use for more than 40 years, gastric bypass limits food intake and changes how the body absorbs food. This procedure results in an early sense of fullness and a sense of satisfaction that reduces the desire to eat.

At Floyd, this procedure is performed using laparoscopic technology to ensure our patients a fast recovery, less pain and a decrease in complication rates.

In this procedure, stapling creates a small stomach pouch. The remainder of the stomach is not removed, but is completely stapled shut and divided from the stomach pouch. The outlet from this newly formed pouch empties directly into the lower portion of the small intestine, thus bypassing calorie absorption. This is done by dividing the small intestine just beyond the duodenum for the purpose of bringing it up and constructing a connection with the newly formed stomach pouch. The other end is connected into the side of the Roux limb of the intestine creating the "Y" shape. The length of either segment of the intestine can be increased to produce lower or higher levels of malabsorption.

 Advantages

  • Weight Loss
    One year after surgery, weight loss averages 60 to 80 percent of patient's excess body weight.  The average excess weight loss after gastric bypass is slightly higher in a compliant patient than with purely restrictive procedures such as sleeve gastrectomy and adjustable gastric banding. Nearly 90 percent of patients maintain 50 to 60 percent excess body weight loss long term.
  • Obesity-Related Health Conditions
    Losing weight can resolve or improve conditions associated with obesity, including type 2 diabetes, high blood pressure, high blood triglycerides, back and joint pain, sleep apnea and even depression.
  • Quality of Life
    As patients lose weight they find routine daily tasks like walking and shopping easier. Engaging in leisure activities is less taxing, and weight-associated insecurities about travel and relationships improve.

Special Considerations and Risks

  • Leakage
    This procedure requires the removal of a portion of the stomach and stapling creates the smaller stomach pouch. Complications can arise if a leak forms at the staple line. This severe postoperative problem is treated with antibiotics. Many cases heal with time. However, the leak can be serious enough to require emergency surgery.
  • Narrowing of the opening between the stomach and small intestine
    This rare complication may require either an outpatient procedure, in which a tube is passed through your mouth to widen (dilate) the narrowed opening, or a corrective surgery.
  • Dumping syndrome
    This is a condition where stomach contents move too quickly through the small intestine causing nausea, vomiting, diarrhea, dizziness and sweating. It's experienced after eating excess sweets or high-fat foods. Patients that eat an appropriate diet should not experience dumping syndrome.
