Roux-en Y Gastric Bypass

A gastric bypass limits the amount of food that you can eat and digest.  In a Roux-en-Y gastric bypass, the stomach is made smaller by creating a small pouch at the top of the stomach using surgical staples.  The resulting pouch can only hold approx. 1/4 cup of food. After the pouch has been created, most of the stomach and part of the intestines are bypassed by attaching (usually stapling) part of the intestine to the small stomach pouch. As a result, a gastric bypass patient cannot eat as much and absorbs fewer nutrients and calories.

This operation can be by open or laparoscopic surgery and allows for less time spent in the hospital and faster recovery and healing time.

Advantages of Gastric Bypass

  • Rapid initial weight loss
  • Approach is minimally invasive approach
  • Has been considered the Gold Standard in weight loss around the world for over two decades
  • Slightly higher total average weight loss reported than with purely restrictive procedures
  • Rapid improvement or resolution of type 2 diabetes and metabolic syndrome

Disadvantages of Gastric Bypass

  • Cutting and stapling of stomach and bowel are required
  • More potential operative complications
  • Portion of digestive tract is bypassed, reducing absorption of essential nutrients
  • Potential complications due to nutritional deficiencies
  • “Dumping syndrome” can occur from high sugar consumption
  • Procedure is not adjustable and difficult to reverse
  • Higher mortality rate

The most common complications include

  • Standard risks associated with major surgery
  • Nausea and vomiting
  • Separation of stapled areas (requires major revisional surgery)
  • Leaks from staple lines (requires major revisional surgery)
  • Nutritional deficiencies require daily supplement

Recovery Timeline

  • Hospital stay is usually 48 – 72 hours
  • Many patients return to normal activity within two and a half weeks
  • Full surgical recovery usually occurs within about three weeks
