Roux-en Y gastric bypass surgery

What is Roux-en Y gastric bypass surgery?

The Roux-en-Y gastric bypass, commonly referred to as gastric bypass, is a well-known weight loss combination procedure that uses both restriction (limiting the size of the stomach) and malabsorption (limiting the amount of calories and nutrients absorbed). 

Why it’s done

Often described as the “gold standard” for weight loss surgery, gastric bypass is a minimally invasive operation performed to help you lose excess weight, and improve quality of life. Most importantly, it is intended to reduce the risk of developing potentially life-threatening obesity related health problems. These include type 2 diabetes, heart disease, high blood pressure, gastroesophageal reflux disease, obstructive sleep apnea, high cholesterol and infertility.

Benefits of bypass surgery:

  • Performed minimally invasively
  • Excellent sustained weight loss
  • Long track record of success

Success statistics

The gastric bypass is associated with excellent primary weight loss and good prolonged sustained weight reduction. As noted this weight loss is associated with improvement in and at times the resolution of the medical conditions previously mentioned.

Risk factors

There are various factors to consider when exploring weight loss surgery—all of which should be discussed with your bariatric surgeon. Complications associated with gastric bypass are different for everyone. Possible risks include:

  • Leaks from intestinal connections
  • Vitamin and mineral deficiencies, if daily prescribed supplements are not taken
  • Mechanical problems with intestines from scarring
  • Without appropriate follow up and adherence to dietary guidelines, patients can regain weight
  • Dumping syndrome – occurs when you don’t follow dietary guidelines. Symptoms may include, vomiting, diarrhea, sweating, flushing, dizziness, and abdominal cramping

Gastric bypass is not recommended for people with Crohn’s disease. Discuss all potentials risks with your doctor.

What to expect 

Roux-en-Y gastric bypass surgery is performed in an inpatient procedure and generally requires a 1 to 3 day hospital stay. This procedure is most often performed laparoscopically but can be done with robotic assistance, when appropriate. The method chosen for the procedure depends on each individual case. You will discuss with your doctor which approach is appropriate for you.

The result of the altered digestive tract is that most of the stomach and a portion of the small intestine are bypassed. “Roux-en-Y” refers to the Y-shaped appearance of the altered small intestine after the bypass is performed.

Recovery

After your surgery, follow-up visits and post-surgical testing at your doctor’s office is required. Patients should be followed by a physician that is qualified to manage post bariatric patients. These appointments are made so that your doctor can keep a close eye on your progress and assist in the overall success of your surgery. At Northwell Health, we consider you a life-long patient after bariatric surgery.

Results

If your initial weight-loss procedure is no longer working, revisional surgery may be an option for you to achieve continued weight loss and improved health. While revisional surgery is generally more complex than the original procedure, our collaborative team of weight loss specialists have the knowledge and expertise to perform these procedures successfully.

The approach chosen for the revisional procedure varies on the patient’s individual needs and is tailored to the goals you are trying to achieve. Speak with one of our experts to determine if you are a candidate for revisional surgery and the best option for you.
