Mini Gastric Bypass Surgery

How Does It Work?

Mini Gastric Bypass Surgery

Mini Gastric Bypass Surgery is a newer version of the RNY gastric bypass using only one malabsorption connection to the small intestine instead of two.

First, the stomach is separated into two sections, the new pouch and bypassed portion of the stomach. The new stomach pouch is created and connected to a bypassed portion of the small intestine.

The New "Mini RNY Pouch"

The new pouch is sleeve-shaped connected to the esophagus. It holds only 3 to 6 ounces of food. This procedure divides the stomach into two different parts; the pouch and the bypassed portion of the stomach.

By utilizing two components of weight loss, patients can expect to lose more weight than procedures like gastric sleeve surgery, gastric balloon, lap band, and gastric plication (which are all restrictive-based bariatric surgeries).

Weight Loss Results

The laparoscopic Mini RNY is not just easier to perform for surgeons, it is also safer in terms of success rate and complications than other procedures. As a simplified form of gastric bypass surgery, the mini gastric bypass is a tool that significantly helps patients lose weight and keep it off long-term.

With the mini gastric bypass surgery, patients lose an average of 70-80% excess weight loss in the first year after surgery. Compared to gastric bypass surgery, the mini RNY offers comparable weight loss with lower complication rates.

  • Significant weight loss
  • Lower complication rate because of being a single anastomosis procedure
  • Short operating time
  • Improves obesity-related health problems
  • Improves quality of life
The time spent recovering after mini gastric bypass surgery is similar to the recovery time with the standard gastric bypass surgery.
