Roux en Y

Phot of laparascopic gastric bypass surgery

What is the most common weight loss surgery performed in the U.S.?

According to the American Society for Bariatric Surgery and the National Institutes of Health, Roux-en-Y gastric bypass is the most frequently performed weight loss surgery in the United States and is the gold standard procedure for weight loss surgery.

What are the advantages of the Roux-en-Y gastric bypass?

Roux-en-Y offers the best balance between weight loss and risk of complications.

University of Maryland bariatric surgeon Mark Kligman, M.D., has a very impressive success rate with this procedure. On average, weight loss can average 80 percent of excess body weight one year after surgery.

Other advantages:

  • The average excess weight loss after the Roux-en-Y procedure is generally higher in a compliant patient than with restrictive procedures.

  • Studies show that after 10 to 14 years, patients on average have only gained back 10 to 13 percent of the lost weight.

  • A 2000 study of 500 patients showed that 96 percent of some associated health conditions studied (back pain, sleep apnea, high blood pressure, diabetes and depression) were improved or resolved.

How is the Roux-en-Y gastric bypass performed?

In Roux-en-Y, the stomach is divided, and a small pouch, which limits calories that can be taken in on a daily basis to less than 1,000, is formed as simultaneously the majority of the stomach is sealed off. A portion of the small intestine is then divided and sewn to the newly created small stomach pouch. This process limits the body's ability to absorb calories. This procedure can be performed as a standard open surgery, or as a laparoscopic surgery.

How is a laparoscopic procedure performed?

Laparoscopic (minimally invasive) surgery involves several very small incisions rather than open surgery, which uses one large incision. Once the patient, who has been given general anesthesia, is asleep, a harmless gas is introduced into the abdomen to move the organs so that the surgeon can work in increased space and can see more when a tiny camera (a laparoscope) is inserted into one incision through a narrow hollow tube (a trocar).

This technique allows the surgeon to view images of the surgery site on a video screen. Then through other trocars inserted into the remaining small incisions, the surgeons introduce and manipulate long narrow surgical instruments that allow performance of the same procedures that take place in traditional open surgeries.

What are the advantages of the laparoscopic approach?

At the University of Maryland Medical Center, we only use the laparoscopic approach for Roux-en-Y because of the many advantages, including quicker recovery and shorter hospital stays, as well as a significantly reduced risk of wound infection. Patients also report less pain and quicker return to normal activity.

Who is a good candidate for this procedure?

Someone approximately 75 pounds overweight with a major obesity-related health problem (like type 2 diabetes, heart disease or sleep apnea) or someone greater than 100 pounds overweight without any other complications may be a good candidate for this type of surgery.

Why come to the University of Maryland Medical Center?
