scar excision/revision surgery / ANYONE?

Major scar REMOVAL- 10 inch by 1.5 inch scar.....plastic surgeon is surgically removing scar

.... a little background history...... when I was 2yrs. old, a city dumpster fell on my, causing me to bleed internally,  having to have surgery. It left a scar, and as I grew, so did the scar -- it is now 10" by 1.5" across my abdomen, right below where my rib cage ends and seriously looks like a set of railroad tracks. My tummy looks like it is smiling. I have insant 'muffin top' because of this scar. Apparently the scar has adhered to muscles, tissue, and lord knows what else.

I am scheduled for surgery October 21st. The surgeon is going to cut out the entire scar, make sure that all the adhesions are 'gone' and then proceed to give me a new 'less visible' scar.

Anyone else have this kind of surgery?
What was your recovery time like?
What should I expect after surgery?
