Dueodenal Switch

I have a male friend who lives in Puerto Rico and weighs about 380. He has finally decided to look into having WLS. Because of his high BMI and a better excess weight loss expectation I suggested to him to have a Dueodenal Switch rather than a Distal RNY.

His insurance is Medicad and Medicare.

Can anyone give me the name or names of some surgeons in PR who perform the DS surgery?  If there are none who do the DS can you recommend any RNY surgeons in PR and also their location. He lives just outside of Aricebo and I believe would be OK with going to San Juan, however, it's more important that the surgeon be competent, skilled than in close proximity.

Thank you,
