Roux-En-Y Gastric Bypass – Banded And Conventional

What Is It?

This procedure has a restrictive as well as a malabsorptive effect. Physically, it restricts food intake; portions sizes after the RNYGB are much reduced with an early feeling of fullness. Over-eating may then cause abdominal discomfort and vomiting. While the majority of the reduction in a patient’s calorie intake is attributable to the restriction, initially there is also an element of malabsorption of fat.

RNYGB also reduces a patient’s appetite. The mechanism by which this occurs is not fully understood, but is related to a change in the normal gut hormonal patterns. Bypassing the first part of a patient’s small intestine affects the production of hormones that control appetite. After RNYGB most patients feel far less hungry, often forgetting to eat. Bypass surgery also affects the hormones that control blood sugar and consequently many diabetic patients become non-diabetic soon after surgery.

How is it performed?

Conventional Roux-en-Y Gastric Bypass (RYGB) is a surgical procedure that can be performed by a minimally invasive surgical method. The volume of the stomach pouch after RYGB is between 30 and 50 ml. The alimentary limb in RYGB is 150-200 cm long, the biliopancreatic limb consists of the 50 cm of small intestine.

Who can undergo this procedure?

  • This operation is ideally suited for patients with Diabetes Mellitus, Hypertension and other obesity – related diseases
  • Operation for sweet eaters
  • Operation for patients with heartburn (GERD/ acidity)

Advantages

  • It is a very successful operation for patients who failed restrictive procedures like balloon, banding and sleeve gastrectomies , causing 50-70 % excess weight loss.
  • It has been found to have a 90-100% remission rate for Diabetes Mellitus for upto 5-15 years after surgery.
  • It is a reversible procedure unlike the sleeve gastrectomy.

Disadvantages

  • Frequent passage of stools.
  • Life-time vitamin and mineral supplements needed after surgery.
  • Conventional upper gastroscopy of duodenum and remnant stomach is not possible.

What is a Banded Roux-en-Y Gastric Bypass?

In this procedure, a GaBP Ring Autolock™ is added above the joint between the stomach and intestine. Like the Banded Sleeve Gastrectomy, this helps in maintenance of weight loss in the long term.
