Having your surgery performed in a country we do not live is generally called medical tourism. The appeal is that in some cases the procedures themselves can be less expensive because the standard of Medical Care may not be as strict outside of the United States.
The problem is that once you get home you do not have the benefit of your surgeons knowledge and expertise to treat you through the postoperative process and take care of any problems should they arise.
While in the short run it may save you money, if you do develop a complication or have a problem it can be far more expensive to take care of here in the United States.
If you do have a problem you certainly may be able to find a surgeon that will help you here in United States but the cost for treating a complication may vary.
I would strongly recommend you have your surgery performed by a Physician in your region who will be there for you if you have any postoperative concerns are issues. I think it just makes better common sense.
