Mini Gastric Bypass vs Gastric Bypass: What’s The Difference?

Bariatric surgeries were introduced in the mid 20th century in order to solve a growing problem: obesity. The first bariatric surgery introduced was the jejuno-ileal gastric bypass, which revolutionized weight loss science and gave the most obese people a chance at a normal life. Over time, more and more procedures were created with slightly altered methods of preventing overheating and reducing the absorption of calories. One of these procedures was named the “mini gastric bypass”.

But what is the difference between the mini gastric bypass and the regular gastric bypass? In this article, we’ll be talking about the mini bypass vs. the bypass and the core differences between the two procedures.

Difference Between Mini Gastric Bypass and Gastric Bypass

The gastric bypass was introduced in the 1960s in order to deal with the growing rates of obesity seen at the time. The Roux-en-Y gastric bypass (RYGB) is a slightly altered version of the original jejuno-ileal gastric bypass which solved some problems that the original had. Now, the Roux-en-Y gastric bypass has a lower risk of causing vitamin deficiencies, staple leaks, and anemia.

The mini gastric bypass, also called the One Anastomosis Gastric Bypass (OAGB), was developed by Dr. Robert Rutledge in 1997 as a simplified form of a previous weight loss procedure. The main draw of this procedure is that it is a simpler, quicker procedure for surgeons to perform and has lower complication rates compared to the Roux-en-Y gastric bypass. This is because it creates only one anastomosis (or loop) to bypass the intestine instead of two like the Roux-en-Y.

These days, the procedures are slightly different than they originally were. One exciting change was the switch from open surgery to laparoscopic surgery. Laparoscopic surgery allows the surgeon to perform procedures by cutting small incisions and inserting a small camera called a laparoscope into the surgical site while the surgeon is performing the procedure. This reduces recovery time and risks of infections and complications. Many procedures that used to require open surgery can now be performed laparoscopically, and the regular and mini gastric bypass procedures are no exception.

Which Is Better: Mini Gastric Bypass or Gastric Bypass?

Although the mini gastric bypass is a simpler, easier procedure, it’s performed differently than the Roux-en-Y gastric bypass and many surgeons simply do not have the training necessary to perform it. And, with the introduction of the gastric sleeve as an easier and similarly effective alternative to both the mini and roux-en-Y gastric bypass procedures, mini gastric bypass no longer has the niche that it once had. As a result, mini gastric bypass is not covered by many insurance providers and it’s harder to find a surgeon that will recommend mini gastric bypass over the RYGB or the gastric sleeve.

Most surgeons still perform a laparoscopic Roux-en-Y gastric bypass. However, we believe that in order to choose the best procedure for you, you will need to consult directly with a surgeon who will explain what they are able to do for you based on your unique needs.
