Roux-en-Y


'gold standard' in
weight loss surgery

 

Today, most experts agree that for patients with morbid obesity who have repeatedly tried and failed to lose weight, the roux-en-Y gastric bypass is the safest surgical weight loss option.

The average gastric bypass patient loses 70 to 80 percent of their excess weight. About half of the weight loss occurs in the first six months after the surgery. After that, the weight loss is more gradual, and generally continues for the next 12 months.

Roux-en-Y comprises 85 percent of bariatric procedures. It has been refined over the last 20 years and these refinements, including improved post-operative care, have resulted in better outcomes.

Surgeons can perform the Roux-en-Y as an open procedure or laparoscopically, through tiny incisions. During the surgery, the stomach is made into a pouch that restricts food intake. A portion of the small intestine is bypassed and attached to the pouch. The bypass reduces the amount of calories and nutrients the body can absorb.

Most iron and calcium are absorbed in the duodenum, which is bypassed after the Roux-en-Y procedure. The decreased absorption of these minerals and of certain B vitamins can cause the onset of anemia, osteoporosis, and metabolic bone disease. Patients are required to take vitamin supplements to avoid these conditions.

Roux-en-Y Procedure

A portion of the stomach is made into a small pouch (ap proximately 30 ccs) in order to restrict food intake.
A section of the small intestine is attached to the pouch. Food bypasses the duodenum and the first portion of the jejunum.

The stoma connecting the stomach pouch to the small intestine is about 12 mm or 1/2 of an inch in diameter. This small outlet slows the rate at which food leaves the pouch, causing a feeling of fullness.
The lower stomach no longer receives food, but it does secrete gastric juices.
After the procedure, patients typically are able to consume only ½ to 1 cup of food at a time for the rest of their lives.
Eating too much sugar or excessive carbohydrates can cause “dumping syndrome,” when stomach contents move too rapidly through the small intestine. Nausea, weakness, perspiration, faintness, and diarrhea can result.

What is the referral process?

Every patient must attend a two-hour educational seminar hosted by Grand Traverse Surgery, PC before a referral can be made. Seminars are held monthly.
