The duodenal switch also commonly known as biliopancreatic diversion with duodenal switch (BPD-DS). It is a type of weight loss surgery treatment that comprises of a restrictive and a malabsorptive aspect. The restrictive part of the surgery involves removing 70% of the stomach while the malabsorptive part involves rerouting a long part of the small intestine.
One of the major goals of this surgery is to reduce the size of the stomach thus making the patient feel full sooner after eating, causing patients to eat less. The rearranged intestines ensure that the body absorbs fewer calories and minerals.
Some strict diet procedures need to be followed by the patients before the surgery. The doctor will recommend a pre-surgery and post-surgery diet plans to the patients that have to be followed strictly.
A large portion of the stomach is reduced to create a banana-shaped pouch connecting the esophagus to the starting portion of the small intestine. Several feet length of the upper part of the small intestine is cut. This piece of the small intestine is then attached to the stomach so that the digestive juices can break down the food coming from the stomach.
After the surgery is performed, the patients are generally advised two to three days’ rest in the hospital. Full recovery time is three to four weeks. There might be slight complications after the surgery is done. Some patients may have trouble swallowing the food as the capacity of the intestines are reduced. About 1 in every 5 patients experience Gastroesophageal reflux disease (GERD) in the first 12 months. The good news is that the GERD rate drops to 3% after 3 years. Some other duodenal switch side effects may include gallstones, indigestion, intolerance due to certain foods, nausea, and vomiting.
