Laparoscopic Roux-en-Y Gastric bypass (with a silastic ring)

How We Do the Operation

The type of Gastric Bypass we generally perform has a silastic rubber band placed above the pouch to the smallbowel anastomosis (joinup). This means that there is more restriction and less risk of weight regain commonly seen with other types of gastric bypass patients. This will occur in 20% or more of these cases and patients risk losing restriction and fullness (satiety). This silastic ring is the key component of the Fobi Pouch Gastric Bypass which is well regarded as providing some of the best results of gastric bypass surgery. This is confirmed by our own data showing 91% excess weight lost at 3 years, (an average of 50.6 kgs lost).

When we do the Gastric Bypass, we want to make a very small pouch out of the upper stomach, to restrict the amount of food which can be eaten. That pouch is separated from the rest of the stomach, which is bypassed, by creating a new pathway into the intestines.

Laparoscopy is done through “ports”, which are tubes that we pass instruments through, to operate on the internal organs. We place several of these in the abdominal wall, through tiny incisions. Whether we do the operation through an incision, or laparoscopically, the basic methods, anatomy, and the results are similar, although the instruments differ.
