Roux-en-Y Bypass Weight Loss Surgery – Parham Doctors’ Hospital


Roux-en-Y gastric bypass is the operation that
we know the most about in our choices of operations. There’s lap band, there’s
sleeve gastrectomy, and Roux-en-Y gastric bypass. We were doin’ the Roux-en-Y gastric bypass in my training 30 years ago. The problem was, 30 years ago, everybody was doing it a little different. There was no standardization
to the bypass, and we didn’t know to teach patients how to use their tool. So we do the bypass,
send them on their way thinking they would do great, but a lot of ’em didn’t. A lot of ’em gained weight back, and a lot of ’em had problems. Fortunately, that’s not the case anymore. The gastric bypass now
is very standardized. We have centers of excellence that kind of watch over
us and watch our data to make sure we’re doing things well, and, in the gastric bypass, what we do is we go in laparoscopically with small instruments,
a camera, and a TV, we find the stomach, we create a small pouch of
the upper part of the stomach. It’s about the size of a hard boiled egg. It holds about four to six ounces of food. We then reroute the intestines so food comes into that small pouch, goes through the intestine bypassing the rest of the stomach, the pancreas, and the liver and the bile, and then we make a second
connection further down that reunites the food and the bile. So food goes one way, digestive
juices go another way, and it’s not until they get to that second connection and travel together that the food is absorbed. So the operation does two things
to help people lose weight. It restricts how much they can eat, about four to six ounces, and it also decreases the amount of that food that they
do eat that’s absorbed. So the patients will eat somewhere around 800 to 1000 calories a day, and they’ll lose about 75%
of their excess body weight. The key, though, is you have
to take care of your tool. So again, we’ve gotta
teach you how to use it. So that means measuring your food so you don’t eat more than
four to six ounces of food because that small stomach
will dilate over time. So if you’re constantly
overeating and stretching it, you lose that restriction
and that sense of fullness. You also dilate the connection between the small bowel and the stomach which, again, all of a sudden that sense of fullness is gone, and patients can regain their weight back. So the key is to take
care of your operation, measure, eat the right foods, and that bypass will take care of you for the rest of your life. Not only will you lose
the weight initially, but it’ll help maintain that weight loss for the rest of your life.
