Laparoscopic Gastric Bypass
Laparoscopic Roux-en-Y Gastric Bypass – As “gastric bypass” implies, this surgical procedure routes food past most of the stomach and the first part of the small intestine. The stomach is modified into a small upper pouch so that only a small amount of food can be eaten at one time. In addition to restricting food intake, a Roux-en-Y gastric bypass reduces nutrient absorption. Roux-en-Y Gastric Bypass, is considered to be one of the most popular and successful bariatric procedures. It has long been known as the ‘gold standard’ of all bariatric procedures. Weight loss is typically dramatic, and co-morbidities can be reduced by 80-90%. This procedure is performed laparoscopically.
Frequently Asked Questions
What is a laparoscopic gastric bypass?
A laparoscopic gastric bypass is a type of surgical procedure which helps patients to lose weight by changing how the stomach and small intestine accommodate food. A human stomach is usually about the size of a fist, but it can expand to accommodate large amounts of food. A gastric bypass reduces the space available in the stomach to the size of an egg and the limited capacity should signal to the patient that he or she is full much earlier. Laparoscopic means that the procedure is carried out inside the body using a laparoscope and special laparoscopic surgical instruments. This restriction keeps the body from absorbing all of the calories from the consumed food.
Why are gastric bypasses used?
Weight loss surgery is designed to help those who have not been able to lose weight even though they have taken traditional steps such as exercising and healthy eating. People with a higher body mass index, or BMI, usually around 40 and those who have a threatening or chronic disorder related to their weight, such as type 2 diabetes or high blood pressure, are good candidates for the procedure. Gastric bypass is meant to work in conjunction with healthy dieting and exercise. The patient must learn to control food portions and increase activity levels to truly benefit from the procedure.
What can I expect after the surgery?
Most patients can between 60-80% of their body weight, or 10 to 20 pounds per month for the first 12 months after the surgery and typically recover very well. Weight loss will slow down and then stop over time. Maintaining activity levels and sticking to a healthy diet are crucial to keeping the weight off long after the procedure. However, studies show that patients maintain 50% of their total weight loss for 20 years or more. Many medical issues can be alleviated by losing weight including: Asthma Gastroesophageal Reflux Disease High Cholesterol and Blood Pressure Obstructive Sleep Apnea Type 2 Diabetes As the excess weight comes off, patients will find it easier to be more active. Traditionally, after surgery, the doctor or a dietitian will create a meal plan or diet to assist the patient with the dietary changes necessary following the surgery as well as maintaining that loss in the future.

Difference between a Gastric Sleeve and a Gastric Bypass
The main differences between sleeve gastrectomy and a bypass gastrectomy are the reshaping of the stomach and the technical procedures to complete the surgery. During a gastric bypass, the doctor surgically reshapes the stomach into a smaller pouch shape and makes changes to the small intestine to connect to the smaller stomach section. The changes include bypassing a large portion of the stomach, the duodenum and a portion of the jejunum sections of the intestines, which reduces the area for calorie absorption. The sleeve is different because it reshapes your stomach but does not bypass any portion of your intestinal track. This allows for additional areas for nutritional absorption in the small intestines. Typically a bypass pouch will hold less food than the stomach area left by the sleeve procedure. Both procedures have similar weight loss results and long-term success at the 5-year mark. The sleeve is a newer innovation and studies are still being conducted. There are pros and cons to each and the surgical team can help answer those questions for you.
