8Calibee*, I had the surgical option both times with my missed miscarriages. I had no idea there were any risks of cervical and endometrial damage until after I'd had the second one. And that was because it took ages for my period to return and for a few months at period time I'd just have cramping and no blood. I worried that there was surgical damage,and there may have been, but fortunately it corrected itself and all is well now(in terms of having regular periods, there may still be damage which will prevent a successful pregnancy).
As for the stats about scar tissue, I have read 1% and 8% on but then read a higher % of 25%, but that seems a huge discrepancy.
My reasons for choosing the surgical option was that I was so distraught I couldn't get my head around having to pass the baby, and was afraid of pain and labouring and passing the baby at home with my children around.I was afraid of frightening them. I also worried that it might take weeks for the whole thing to finish,and just wanted to move on more quickly so I could ttc again. Of course after the second one it was ages til I could ttc again anyway, so it didn't really turn out as I'd hoped. Having a second ERPC put my chances of having scarring up to 32%, and for all I know I may have scarring which will cause further miscarriage(and I have had one more miscarriage since then). But I did what felt right at the time, and actually had no idea about the scarring.
I guess you have to weigh up each option and decide what is best for you. I found the anesthetic made me feel very tired for ages afterwards (at least that's what I put it down to), I think it was a couple of weeks of feeling really knackered, but grief will also do that.
Just try to rest and try not to worry.
