Roux-En-Y Gastric Bypass

Introduction to Gastric Bypass

At Core Specialist Group, we’re able to offer Roux-En-Y gastric bypass (sometimes referred to by the abbreviation 'RYGB' or simply as a 'gastric bypass') at several locations throughout Queensland, including Lismore, Tugun, Southport and more. A gastric bypass involves altering the flow of food through the gastrointestinal tract by bypassing a section that includes the stomach and the upper section of the small intestine.

This has the effect of reducing the surface area of the gut where nutrients are absorbed into the body.

Most Roux-En-Y procedures are carried out using laparoscopic / minimally invasive surgical techniques, although where the patient has had abdominal surgery previously a laparoscopic approach may not be possible and so may be performed as conventional open surgery.

The Roux-En-Y gastric bypass has a number of advantages over other bariatric weight loss approaches. These are...

  • The procedure may be able to be reversed at a later date if required.
  • Much lower incidence of reflux than other approaches.
  • The resulting metabolic change helps in the treatment for resistant diabetes.
  • Most successful weight loss procedure in terms of long-term results (in fact is considered the 'benchmark' weight loss procedure).
  • Considered the safest revision procedure where laparoscopic gastric banding has not worked.

The Gastric Bypass Procedure

The top section of the stomach is formed into a small pouch with a volume of roughly 15ml (a normal stomach has a capacity of 1500ml or 1.5l). Then the middle section of the small intestine (the jejunum) is divided, and the upper end is attached to the pouch and the lower end is reconnected to the small intestine at a point approximately a metre away from the pouch.

Postoperative Instructions for a Gastric Bypass

As is the case with all surgical weight loss procedures, the long-term success of a Roux-En-Y gastric bypass hinges on the adoption of a new regime of diet and exercise. Where this does not happen, many patients regain weight. Where patients are completely committed to their new lifestyle, they can expect to lose on average 60% of their excess weight.

As well as the permanent changes to lifestyle in terms of diet and exercise, patients undergoing a Roux-En-Y gastric bypass will also need to take nutritional supplements every day on a permanent basis.
