Gastric Bypass Surgery

Surgical Weight Loss

The goal of weight loss surgery is to reduce the body’s ability to absorb and store calories. This result is achieved by using either restrictive or malabsorptive bariatric procedures.

Restrictive procedures reduce the size of the stomach, limiting the volume of food that can be consumed at one time. Restrictive procedures include vertical banded gastroplasty (VBG), adjustable gastric banding (AGB) and Roux-en-Y gastric bypass (RYGB) – although gastric bypass is also malabsorptive as well.

Malabsorptive procedures reduce your body’s ability to store calories by diverting food away from the parts of your digestive system that absorb calories. Largely malabsorptive procedures include biliopancreatic diversion (BPD) and biliopancreatic diversion with duodenal switch (BPD-DS).

While vertical banded gastroplasty has largely fallen out of favor, other procedures have proven effective for achieving and maintaining healthier weight.¹ Each has also proven effective for reversing or minimizing weight-related health problems.¹

Gastric Bypass Surgery

Gastric bypass is the most common bariatric surgery performed in the United States.¹ It offers a combination of both restrictive and malabsorptive procedures, which appears to be a very effective recipe for weight loss. Moreover, it is considered the gold standard of surgical treatment.¹

While gastric bypass is becoming more common, this elective surgery has serious risks. Potential complications after gastric bypass include leakage of the digestive tract, which requires re-operation and can cause death. Surgeons must have excellent visualization, dexterity and control to complete this technically challenging operation successfully.

The most common approach to gastric bypass is through a large abdominal incision. This approach generally provides adequate visualization and access, but causes patients significant pain and trauma.
