Biliopancreatic Diversion with Duodenal Switch
What’s Involved With Biliopancreatic Diversion/Duodenal Switch Surgery?
Biliopancreatic diversion with duodenal switch is a two-part surgical weight loss treatment that combines elements of both a sleeve gastrectomy and a gastric bypass. It involves the removal of approximately half (50 percent) of the stomach volume, and bypassing of approximately three-quarters of the small intestine (75 percent).
The first part of the small intestine (the duodenum) is disconnected then reattached to the end (distal) of the small intestine. As a result, when the patient eats food passes directly through the newly-created stomach into the last section of the small intestine. Following BPD-DS, patients experience significant changes in the capacity of their stomach and their metabolic functioning.
How Does Biliopancreatic Diversion/Duodenal Switch Promote Weight Loss?
Because this procedure dramatically reduces the capacity of the stomach, patients feel fuller on much less food than they did prior to the surgery, resulting in a significant reduction in caloric intake.
The anatomical changes resulting from a biliopancreatic diversion with duodenal switch also reduce dietary fat absorption by up to 70 percent. The hormones in the gut and blood sugar fluctuations that trigger feelings of hunger and fullness are impacted, which helps patients manage their food intake without feeling deprived.
Do I Qualify For Biliopancreatic Diversion Surgery?
Biliopancreatic diversion surgery is an invasive weight loss treatment for people who have a body mass index (BMI) of 50 or higher.
Biliopancreatic diversion with duodenal switch is considered to be a high-risk operation due in part to the fact that it is only performed on people who are classified as ‘super-obese’, and therefore tend to have comorbid conditions that can increase their chances of experiencing post-operative complications.
BPD-DS surgery leads to the greatest average weight loss among all the types of bariatric procedures currently offered; most patients who undergo a biliopancreatic diversion lose about 70 percent of their excess weight within 24 months of the procedure.
Researchers have recently discovered a positive link between biliopancreatic diversion surgery and a notable reduction in the symptoms of type-2 diabetes. Many BPD-DS patients have reported a complete remission of their type-2 diabetes within the first 5 years following their biliopancreatic diversion surgery.
Can A Biliopancreatic Diversion Be Reversed?
Due to the anatomical changes made during surgery, a biliopancreatic diversion cannot be reversed, however, it can be modified using laparoscopic surgical techniques.
When Is A Biliopancreatic Diversion Revision Needed?
While the vast majority of patients who have a biliopancreatic diversion will never need additional surgery, in some cases excessive side effects such as severe gastric distress or failure to lose sufficient weight need to be treated with a revision surgery.
