Biliopancreatic Diversion with Duodenal Switch Dallas (BPD/DS) Gastric Bypass
The Biliopancreatic Diversion with Duodenal Switch Dallas – abbreviated as BPD/DS – is a procedure with
two components. First, a smaller, tubular stomach pouch is created by removing
a portion of the stomach, very similar to the sleeve gastrectomy.
The Procedure
The
duodenum, or the first portion of the small intestine, is divided just past the
outlet of the stomach. Roughly three-fourths of the small intestine is bypassed
by the food stream.
Lastly,
the BPD/DS, similar to the gastric bypass and sleeve gastrectomy, affects guts
hormones in a manner that impacts hunger and satiety as well as blood sugar
control. The BPD/DS is considered to be the most effective surgery for the
treatment of diabetes among those that are described here.
Advantages
1.
Results in greater
weight loss than RYGB, LSG, or AGB, i.e. 60 – 70%
percent excess weight loss or greater, at 5 year follow up
2.
Allows patients to
eventually eat near “normal” meals
3.
Reduces the absorption
of fat by 70 percent or more
4.
Causes favorable
changes in gut hormones to reduce appetite and improve satiety
5.
Is the most effective
against diabetes compared to RYGB, LSG, and AGB
Disadvantages
1.
Has higher
complication rates and risk for mortality than the AGB, LSG, and RYGB
2.
Requires a longer
hospital stay than the AGB or LSG
3.
Has a greater
potential to cause protein deficiencies and long-term deficiencies in a number
of vitamin and minerals, i.e. iron, calcium, zinc, fat-soluble vitamins such as
vitamin D
4.
Compliance with
follow-up visits and care and strict adherence to dietary and vitamin
supplementation guidelines are critical to avoiding serious complications from
protein and certain vitamin deficiencies
