The duodenum, or first portion of the small intestine, is divided just past the outlet of the stomach. During a duodenal switch, a segment of the distal (last portion) small intestine is brought up and connected to the outlet of the newly created stomach.
Now when the patient eats, food goes through a newly created tubular stomach pouch and empties directly into the last segment of the small intestine. Roughly three-fourths of the small intestine is bypassed by the food stream.
Why Get The Duodenal Switch?
This procedure is done to decrease the amount of acid produced by the remaining stomach. Gastrin, a hormone produced by G-cells in the antrum (cavity within a bone), is responsible for stimulating the upper stomach to produce acid. After entering the upper stomach, food passes through a newly created connection (anastomosis) into the small intestine (alimentary limb). The bile and pancreatic secretions pass through the bypassed biliopancreatic channel and connect with the alimentary channel (where food travels) approximately 20 to 40 inches (50to 100 cm) from the colon. Some of these secretions are reabsorbed in this channel before meeting the alimentary tract. The part of the intestines where bile and pancreatic fluids (from the biliopancreatic channel) and food (from the alimentary channel) mix is called the common channel. Surgeons use various formulas to determine the appropriate length of the alimentary and common channels.
