Abdominoplasty @ 300lbs

I went to a my doctor today for a routine fill and he began feelin around my hips and upper thighs. He said, "I can feel your bone". He said that he thinks I'm ready for abdominoplasty. I was like (because I couldn't beleive what I was hearing) "how much more weight do you think I need to lose?". He said, I think you're ready now. At the most maybe another 20 lbs, but I really think you're ready now. I was shocked. I was banded a year ago (2/13/09) and have only lost just over 65lbs (I was hoping to have lost closer to 100). Does this sound right? A abdominoplasty at 300 lbs? Really? Has anyone ever heard of this? I would think it would look weird. I have another 100+ lbs to lose - would I need another then? My mother who is a nurse said she once observed an abdominoplasty of someone who was far hevier than I where they removed 60+ lbs of skin and fat from her stomach. The prospect is exciting but 'm confused. I thought I would need to be near or at my goal weight. Please let me know what you all think.
