Biliopancreatic diversion with duodenal switch

The biliopancreatic diversion with a duodenal switch (BPD-DS) is a less commonly performed but very effective bariatric procedure that has been in existence for more than 20 years. It is particularly effective for the resolution of diabetes and is associated with the highest weight loss among other bariatric operations. Typically, the BPD-DS is not associated with postgastrectomy symptoms, such as dumping and marginal ulceration. Because of its complexity, it has usually been performed by laparotomy in the past; but, more recently, minimally invasive techniques are being used with acceptable risk.
