Thank you for posting your questions. My name is Dr.Javier Soto. So abdominal etching or high definition Liposuction is a technique developed in Colombia, and this is why it so common in our country. I believe there are some doctors in the US that have been here in Colombia for training and have gone back and started doing it, I always recommend you to assist to a consultation with a Board Certificate Surgeon even if you have to go out of the country, in Colombia you will be able to perform both of the surgerys at the same time, we will use your own fat to increase the size of your buttock and you will achieve an athletic abdominal six pack, Please keep giving us feedback of your process, and I hope my answer comes to help.
