Bariatric Surgery

When diet, exercise and non-surgical treatments are not enough, it may be time to consider bariatric surgery, also known as weight-loss surgery. Bariatric surgery aims to help people lose weight and reduce their risk of developing life-threatening health problems associated with excessive body fat.

Obesity is a disease that affects an estimated 93 million Americans. Environmental and genetic factors can cause unhealthy weight gain that dieting or exercising alone cannot control. Although some people can improve their lifestyle and lose weight by themselves, others may benefit more from weight-loss surgery.

Bariatric Surgical Procedures

Some of the advanced bariatric surgical procedures we perform at Foundation Surgical Hospital of San Antonio include:

Laparoscopic Roux-en-y Gastric Bypass

This procedure involves surgical stapling to reduce the stomach to the size of a small “pouch,” which restricts the amount of food required for a patient to feel full (satiety). This procedure is performed laparoscopically (minimally invasive) and generally requires a two-to-three-day hospital stay and a two-to-three-week recovery.

  • Restrictive and malabsorptive components to the procedure
  • Complex procedure affecting multiple areas of the abdomen
  • Lower stomach remains healthy and intact
  • Less tolerance for foods high in sugar and fat
  • Requires long-term vitamin and mineral supplementation
  • Does not require the implantation of a foreign device
  • Initial and sustained weight loss ranging from 60% to 75% of excess body weight
  • Not reversible

Sleeve Gastrectomy

In this procedure, a portion of the stomach is removed. The remaining stomach is the shape of a slender tube that greatly limits the amount of food that can be consumed. This procedure is also performed laparoscopically (minimally invasive) and generally requires a two-to-three-day hospital stay. Recovery may take two to three weeks.

  • Perioperative risk appears low, even in high-risk patients
  • Requires long-term vitamin and mineral supplementation
  • Does not require the implantation of a foreign device
  • Weight loss may range from 33% to 83% of excess body weight
  • Irreversible, but can be converted into a gastric bypass

Lap-Band Removal

Duodenal & SADI Switch Procedures

The SADI procedure combines sleeve gastrectomy with intestinal bypass to promote weight loss. It's performed by removing about 80% of the stomach to create a tube-shaped sleeve and separating the top part of the small intestine (duodenum) just below the stomach.
