I had my surgery in Monterrey almost five years ago with Dr. Francisco Barrera Rodriguez. He is with the Monterrey Gastro & Bariatric Group. My experience with them was awesome. They provide all instructions ahead of time such as itinerary, preop and postop info. I had surgery on Thursday afternoon and was discharged on Saturday at noon. They answered all my questions even the stupid ones. They don't rush you through anything and they run all the preliminary testing in house (EKG, blood tests, nutritional eval). I am not sure if any of their process has changed, but that was my experience at that time. Oh and they assign a nutritionist and office personnel who are available throughout the process. One thing I did do was stay in Monterrey for a few days just in case I had any complications. The drive from Texas was about 6 hours so not too bad. If you have any specific questions I'll be happy to answer them.
