Scar tissue

Esther • Ectopic at 9 weeks lost right tube. TTC baby #2
Hi ladies. I had a emergency extopic April last year. We have been ttc since then with no luck. Just saw an IVF doctor has suggest I go in for surgery to check scar tissue and any other problems. He has said due to the serveity of the ectopic he is 90% sure that there is scar tissue blocks something. 
Question has anyone had this type of surgery and did it work?
