Advantages: Roux-en-Y (RNY)

RNY is currently the most widely used and recognized gastric bypass surgeries available for the morbidly obese. This surgery involves creating a small (less than one ounce) vertically oriented stomach pouch, as well as a bypass of most of the stomach and a varying amount of small intestine. As a result, weight loss is accomplished both by restriction of food and by malabsorption of nutrients.

The advantages to performing the gastric bypass laparoscopically are that it yields cosmetically superior results and the recovery is faster. Some long-term problems, such as incisional hernias, may also occur less frequently.

Substantial weigh loss occurs in the great majority of patients after Roux-en-Y gastric bypass (RNY). The vast majority of patients are satisfied or very satisfied with the results of the surgery. Losing about 50% of one’s excess weight is considered a satisfactory weight loss, although weight loss after RNY frequently approximates 75% of excess weight.

After losing this amount of weight, patients usually feel physically and mentally better. Preoperative comorbidities such as diabetes, hypertension, stress incontinence, back pain, knee pain, heel spurs, sleep apnea and other complications of obesity are usually either improved or eliminated altogether.

With this procedure a portion of the stomach is sectioned off, creating a small pouch for reduced food intake. Because the pouch will usually hold about one ounce of food or less, a feeling of fullness after just a few bites is one way weight loss is achieved. In addition, the Roux-en Y procedure greatly controls food intake, a resulting dumping condition helps to control intake of sweets and the procedure is  reversible in an emergency - though this procedure should be thought of as a permanent

Multiple studies have documented that severe obesity is associated with very high risk of health problems, early death, and cancer.  In fact, the loss of as little as 10% of excess weight has been shown to reduce or eliminate medications for associated hypertension and diabetes.

In addition patients may resume exercise and become more active. The average excess weight loss after the Roux-en-Y procedure is generally higher in a compliant patient than with purely restrictive procedures. One year after surgery, weight loss can average 77% of excess body weight.

Additional studies show that after 10 to 14 years, 50-60% of excess body weight loss has been maintained by some patients.  Some reports have shown that over 90% of certain associated health conditions studied (back pain, sleep apnea, high blood pressure, diabetes and depression) were improved or resolved.

Overall improved self-esteem and establishing a new healthier lifestyle can be the end result.

One other great advantage of the Roux-en-y procedure is that it is available using laproscopic techniques. In these instances, the benefits of the laparoscopic approach include:

  • Shorter length of stay in the hospital (usually two nights)
  • Quicker recovery
  • Less time off work
  • Less pain post-operatively
  • Reduced risk of hernias and wound infections
  • Cosmetically more appealing scars
