Revise 8years Gastric bypass
DS stands for Duodenal Switch. (The duodenum is the uppermost portion of your small intestine.) Have you tried posting this on the DS board here? You can also find a lot of good info on the DS, and a list of surgeons, at www.bariatricfacts.org. There are also several DS-specific FB groups you might want to check out.

Have you had your pouch looked at? What are the reasons you want a revision? Does your insurance cover revisions?
