Gastric Bypass

Roux en Y (RNY) or gastric bypass is a restrictive procedure that staples off an approximate 1/2 – 1 ounce stomach pouch at the upper portion of the stomach.

A section of small bowel is then attached to the pouch via a small opening, which is to simulate the pyloric valve. Narrowing and or blockages can take place at this small opening. Ulceration can also happen at the area where the small bowel and the stomach tissue are attached.

The pyloric valve is bypassed in this procedure. Because of the small pouch size vomiting can take place if food is not properly chewed or food is eaten too fast or too large a volume. Dumping syndrome is also takes place when consuming high sugar containing food.

History.

It’s an interesting sidebar to note that Dr. Mason is the only surgeon to devise two different and well-received procedures for the treatment of obesity. You’ll remember that he introduced the VBG as well, almost two decades after he invented the gastric bypass procedure. Considered the “Father of Bariatric Surgery,” he also founded the American Society for Bariatric Surgery (ASBS) in 1976.

An important step in the growth of gastric bypass surgery came in 1993, when private practitioners Dr. Alan Wittgrove and Dr. Wesley Clark of San Diego, California, co-developed a less-invasive, laparoscopic method of performing the procedure. Instead of making one large incision in the abdomen, they made several small incisions and operated remotely using long, slender instruments and a narrow-shafted camera to visualize the operative field. Patients experienced less pain and scarring, and the overall hospital stay and recovery time were shortened. Today, about half of all patients meet the criteria for the laparoscopic approach.
