Is It Healthy and Safe to Not Have Drains After Having Tumescent Liposuction? (photo)

I am looking for a good PS and have met with 4 in the Houston and surrounding areas. They have all been wonderful but one PS informed me that I would not have drains after the procedure. Yet, all the other doctors said I would. Are drains needed? What are the pros and cons to having them? No mess sounds too good to be true. I am 34 years old, 5'7, 190 lbs with most of it in the stomach and thighs. I have had two kids vaginal with the youngest 6 yrs old and no stretch marks.
